Transformational Learning

Transformational learning is the type of experience that its outcome can bring forth a level of new meaning in your life. This learning cycle of intricate tasks is broken down into four stages, recognizing a significant problem, confronting it intensely, finding a solution, and integrating a new perspective and a new set of assumptions into your life pattern. These four phases create the transformational process and requires extreme mental concentration and careful consideration. The intensity of this procedure is often painful and stressful, hence forth the old saying â€Å"no pain, no gain†.First, you must know what the problem is that you are facing and acknowledge it. Then, you must face the problem with an extreme effort. Once these steps are completed and only then, can you start finding a solution. The solution you find will give you a new view. Based upon this outcome, your newly acquired view must be integrated into your life pattern. Transformation on this level is o ften wanted but it does not come easy. These â€Å"before† and â€Å"after† states are the points that show us our personal growth. The most transformational learning experience in my life has been the discussion to go back to school.The fear of working, having a family, and making time to study and being successful in my studies presented a great problem to me. How to balance these three demanding dimensions of my life and still be the same person was puzzling. Through a trial and error process, I redefined my life pattern, taking bits of personal and casual time to maximize my effort of pursuing my goal. By putting all my focus through my spare time in my work week, it opened up extra time on my weekend to spend with my family. This new pattern I developed has brought harmony and balance to my life.

A Dirty Job Chapter 21

21 COMMON COURTESY Charlie was torn – he really wanted to take his sword-cane, but he couldn't carry it while using the crutches. He considered duct-taping it to one of the crutches, but he thought that might attract attention. â€Å"You want me to go with you?† Ray asked. â€Å"I mean, you okay to drive, with your leg and all?† â€Å"I'll be fine,† Charlie said. â€Å"Someone needs to watch the store.† â€Å"Charlie, before you go, can I ask you something?† â€Å"Sure.† Don't ask, don't ask, don't ask, Charlie thought. â€Å"Why did you need me to find these two women?† You robot-necked bastard, you had to ask. â€Å"I told you, estate stuff.† Charlie shrugged. No big deal, let it go, nothing to see here. â€Å"Yeah, I know you told me that, and normally that would make sense, but I found out a lot about these two while looking for them – no one in either of their families has died recently.† â€Å"Funny thing,† Charlie said, juggling his keys, the cane, his date book, and his crutches by the back door. â€Å"Both bequests were from nonrelatives. Old friends.† No wonder women don't like you, you just won't leave things alone. â€Å"Uh-huh,† Ray said, unconvinced. â€Å"You know, when people run, when they go as far as faking their own death to get away, they are usually running from something. Are you that something, Charlie?† â€Å"Ray, listen to yourself. Are you back on your serial-killer thing? I thought Rivera explained that.† â€Å"So this is for Rivera?† â€Å"Let's say he's interested,† Charlie said. â€Å"Why didn't you just say so?† Charlie sighed. â€Å"Ray, I'm not supposed to talk about this stuff, you know that. Fourth Amendment and all. I came to you because you're good, and you have contacts. I depend on you and I trust you. I think you know that you can depend on me and trust me, right? I mean, in all these years, I've never put your disability pension in jeopardy by being careless about our arrangement, have I?† It was a threat, however subtle, and Charlie felt bad for doing it, but he just couldn't let Ray continue to push on this, particularly since he was in unexplored territory himself – he didn't even know what kind of bluff he was covering. â€Å"So Mrs. Johnson isn't going to end up dead if I find her for you?† â€Å"I will not lay a hand on Mrs. Johnson or Mrs. Pojo†¦Mrs. Pokojo – or that other woman either. You have my word on it.† Charlie raised his hand as if swearing on a Bible and dropped one of his crutches. â€Å"Why don't you just use the cane?† Ray said. â€Å"Right,† Charlie said. He leaned the crutches on the door and tried his weight on the bad leg and the cane. The doctors had, indeed, said that it was just a flesh wound, so there was no tendon damage, just muscle, but it hurt like hell to put any weight on that foot. The cane would work, he decided. â€Å"I should be back to relieve you before five.† He limped out the door. Ray didn't like being lied to. He'd had quite enough of that from his desperate Filipinas and was becoming sensitive about being taken for a fool. Who did Charlie Asher think he was fooling? As soon as he got the store squared away, he'd give Rivera a call and see for himself. He went out into the store and did a little dusting, then went to Charlie's â€Å"special† rack, where he kept the weird estate items that he made such a fuss about. You were only supposed to sell one to each customer, but Ray had sold five of them to the same woman in the last two weeks. He knew he should have said something to Charlie, but really, why? Charlie wasn't being open with him about anything, it seemed. Besides, the woman who bought the stuff was cute, and she'd smiled at Ray. She had nice hair, a cute figure, and really striking light blue eyes. Plus there was something about her voice – she seemed so, what? Peaceful, maybe. Like she knew that everything was going to be okay and no one needed to worry. Maybe he was projecting. And she didn't have an Adam's apple, which was a big plus in Ray's book lately. He'd tried to get her name, even get a look at something in her wallet, but she'd paid in cash and had been as careful as a poker player covering her cards. If she'd driven, she'd parked too far away for him to see her get into her car from the store, so there was no license number to trace. He resolved to ask her name if she came in today. And she was due to come in. She only came in when he was working alone. He'd seen her check through the window once when he was working with Lily, and only came into the store later when Lily was gone. He really hoped she'd come in. He tried to calm himself down for his call to Rivera. He didn't want to seem like a rube to a guy who was still on the job. He used his own cell phone for the call so Rivera would see it was him calling. Charlie didn't like leaving Sophie for this long, given what had happened a few days ago, but on the other hand, whatever might be threatening her was obviously being caused by his missing these two soul vessels. The quicker he fixed the problem, the quicker the threat would be diminished. Besides, the hellhounds were her best defense, and he'd given express instructions to Mrs. Ling that the dogs and Sophie were not to be separated for any amount of time, for any reason. He took Presidio Boulevard through Golden Gate Park into the Sunset, reminding himself to take Sophie to the Japanese Tea Garden to feed the koi, now that her plague on pets seemed to have subsided. The Sunset district lay just south of Golden Gate Park, bordered by the American Highway and Ocean Beach on the west, and Twin Peaks and the University of San Francisco on the east. It had once been a suburb, until the city expanded to include it, and many of its houses were modest, single-story family dwellings, built en masse in the 1940s and '50s. They were like the mosaics of little boxes that peppered neighborhoods across the entire country in that postwar period, but in San Francisco, where so much had been built after the quake and fire of '06, then again in the economic boom of the late twentieth century, they seemed like anachronisms from both ends of time. Charlie felt like he was driving through the Eisenhower era, at least until he passed a mother with a shaved head and tribal tattoos on her scalp pushing twins in a double stroller. Irena Posokovanovich's sister lived in a small, one-story frame house with a small covered porch that had jasmine vines growing up trellises on either side and springing off into the air like morning-after-sex hair. The rest of the tiny yard was meticulously groomed, from the holly hedge at the sidewalk to the red geraniums that lined the concrete path up to the house. Charlie parked a block away and walked to the house. On the way he was nearly run over by two different joggers, one a young mother pushing a running stroller. They couldn't see him – he was on track. Now, how to go about getting in? And then what? If he was the Luminatus, then perhaps just his presence would take care of the problem. He checked around back and saw that there was a car in the garage, but the shades were drawn on all the windows. Finally he decided on the frontal approach and rang the doorbell. A few seconds later a short woman in her seventies wearing a pink chenille housecoat opened the door. â€Å"Yes,† she said, looking a little suspicious as she eyed Charlie's walking cast. She quickly flipped the lock on the screen door. â€Å"Can I help you?† It was the woman in the picture. â€Å"Yes, ma'am, I'm looking for Irena Posokovanovich.† â€Å"Well, she's not here,† said Irena Posokovanovich. â€Å"You must have the wrong house.† She started to close the door. â€Å"Wasn't there a death notice in the paper a couple of weeks ago?† Charlie said. So far, his awesome presence as the Luminatus wasn't having much of an effect on her. â€Å"Well, yes, I believe there was,† said the woman, sensing an out. She opened the door a little more. â€Å"It was such a tragedy. We all loved Irena so much. She was the kindest, most generous, most loving, attractive – you know, for her age – well-read – â€Å" â€Å"And evidently didn't know that it's considered common courtesy when you publish a death notice to actually die!† Charlie held out the enlarged driver's-license picture. He considered adding aha! but thought that might be a little over-the-top. Irena Posokovanovich slammed the door. â€Å"I don't know who you are, but you have the wrong house,† she said through the door. â€Å"You know who I am,† Charlie said. Actually, she probably had no idea who he was. â€Å"And I know who you are, and you are supposed to have died three weeks ago.† â€Å"You're mistaken. Now go away before I call the police and tell them that there's a rapist at my door.† Charlie gagged a little, then pushed on. â€Å"I am not a rapist, Mrs. Poso†¦Posokev – I'm Death, Irena. That's who I am. And you are overdue. You need to die, this minute if possible. There's nothing to be afraid of. It's like going to sleep, only, well – â€Å" â€Å"I'm not ready,† Irena whined. â€Å"If I was ready I wouldn't have left my home. I'm not ready.† â€Å"I'm sorry, ma'am, but I have to insist.† â€Å"I'm sure you're mistaken. Perhaps another Mrs. Posokovanovich.† â€Å"No, here it is, right here in the calendar, with your address. It's you.† Charlie held his date book turned to the page with her name on it up to the little window in the door. â€Å"And you say that that is Death's calendar?† â€Å"That's correct, ma'am. Notice the date. And this is your second notice.† â€Å"And you are Death?† â€Å"That's right.† â€Å"Well, that's just silly.† â€Å"I am not silly, Mrs. Posokovanovich. I am Death.† â€Å"Aren't you supposed to have a sickle and a long black robe?† â€Å"No, we don't do that anymore. Take my word for it, I am Death.† He tried to sound really ominous. â€Å"Death is always tall in the pictures.† She was standing on tiptoe, he could tell the way she kept bouncing up by the little window to get a look at him. â€Å"You don't seem tall enough.† â€Å"There's no height requirement.† â€Å"Then could I see your business card?† â€Å"Sure.† Charlie took out a card and held it against the glass. â€Å"This says ‘Purveyor of Fine Vintage Clothing and Accessories.'† â€Å"Right! Exactly!† He knew he should have had a second set of business cards printed up. â€Å"And where do you think I get those things? From the dead. You see?† â€Å"Mr. Asher, I'm going to have to ask you to leave.† â€Å"No, ma'am, I'm going to have to insist that you pass away, this instant. You're overdue.† â€Å"Go away! You are a charlatan, and I think you need psychological help.† â€Å"Death! You're fucking with Death! Capital D, bitch!† Well, that was uncalled for. Charlie felt bad the second he said it. â€Å"Sorry,† he mumbled to the door. â€Å"I'm calling the police.† â€Å"You go ahead, Mrs. – uh – Irena. You know what they'll tell you, that you're dead! It was in the Chronicle. They hardly ever print stuff that's not true.† â€Å"Please go away. I practiced for a long time so I could live longer, it's not fair.† â€Å"What?† â€Å"Go away.† â€Å"I heard that part, I mean the part about practicing.† â€Å"Never you mind. You just go take someone else.† Charlie actually had no idea what he would do if she let him in. Maybe he had to touch her for his Death abilities to kick in. He remembered seeing an old Twilight Zone as a kid, where Robert Redford was Death, and this old lady wouldn't let him in, so he pretended to be injured, and when she came to help him†¦ALA-KAZAM! She croaked, and he peacefully led her off to Hole in the Wall, where she helped him produce independent movies. Maybe that would work. He did have the cast and the cane going for him. He looked up and down the street to make sure that no one could see him, then he lay down, half on the little porch, half on the concrete steps. He threw his cane against the door and made sure that it clattered loudly on the concrete, then he let out what he thought was a very convincing wail. â€Å"Ahhhhhhhhh, I've broken my leg.† He heard footsteps inside and saw gray hair at the little window, bouncing a little so she could see out. â€Å"Oh, it hurts,† Charlie wailed. â€Å"Help.† More steps, the shade in the window to the right of the door parted and he saw an eye. He grimaced in fake pain. â€Å"Are you all right?† said Mrs. Posokovanovich. â€Å"I need help. My leg was hurt before, but I slipped on your steps. I think I've broken something. There's blood, and a piece of bone sticking out.† He kept his leg below the level where she could see it. â€Å"Oh my,† she said. â€Å"Give me a minute.† â€Å"Help. Please. The pain. So – much – pain.† Charlie coughed the way cowboys do when they are dying in the dirt and things are getting all dark. He heard the latch being thrown, and then the inner door opened. â€Å"You're really hurt bad,† she said. â€Å"Please,† Charlie said, holding his hand out to her. â€Å"Help me.† She unlatched the screen. Charlie suppressed a grin. â€Å"Oh, thank you,† he gasped. She threw open the screen door and blasted him in the face with a stream of pepper spray. â€Å"I saw that Twilight Zone, you son of a bitch!† The doors slammed. The latch was thrown. Charlie's face felt like it was on fire. When he could finally see well enough to walk, as he limped back to his van, he heard a female voice say, â€Å"I'd have let you in, lover.† Then a chorus of spooky-girlish laughter erupted from the storm sewer. He backed against the van, ready to draw the sword from the cane, but then he heard what sounded like a small dog barking in the sewer. â€Å"Where did he come from?† said one of the harpies. â€Å"He bit me! You little fucker!† â€Å"Get him!† â€Å"I hate dogs. When we take over, no dogs.† The barking faded away, followed by the voices of the sewer harpies. Charlie took a deep breath and tried to blink the pain out of his eyes. He needed to regroup, but then he was taking the old lady down, pepper spray or not. It took him the better part of an hour to get into position, but once he was ready, he put down the cinder block, flipped open his cell phone, and dialed the number he'd gotten from information. A woman answered. â€Å"Hello.† â€Å"Ma'am, this is the gas company,† Charlie said in his best gas-company voice. â€Å"My grid is showing pressure loss at your address. We're sending a truck right out, but you need to get everyone out of the house, right now.† â€Å"Well, I'm the only one here right now, but I'm sorry, I don't smell gas.† â€Å"It may be building up under the house,† Charlie said, feeling proud of himself for being quick on his feet. Is there anyone else in the house?† â€Å"No, just me and my kitty, Samantha.† â€Å"Ma'am, please take the cat and go out by the street. Our truck will meet you there. Go right now, okay?† â€Å"Well, all right.† â€Å"Thank you, ma'am.† Charlie clicked off. He could feel movement inside of the house. He moved right to the edge of the porch roof and raised the concrete cinder block over his head. It'll look like an accident, he thought, like a cinder block fell off the porch roof. He was glad that no one could see him up here. He was sweating from the climb, his armpits stained, his trousers wrinkled. He heard the door open and got ready to throw the cinder block as soon as his target emerged from under the roof. â€Å"Good afternoon, ma'am.† A man's voice, out by the street. Charlie looked down to see Inspector Rivera standing at the sidewalk, having just climbed out of an unmarked car. What the hell was he doing here? â€Å"Are you the gas company?† said Mrs. Posokovanovich. â€Å"No, ma'am, I'm from the San Francisco police.† He flashed his badge. â€Å"They told me there was a gas leak,† she said. â€Å"That's been taken care of, ma'am. Could you step back inside and I'll check with you in a minute, okay?† â€Å"Well, okay, then.† Charlie heard the doors open and close again. His arms were trembling from holding the cinder block over his head. He tried to breathe quietly, thinking that the sound of his wheezing might attract Rivera's attention, make him visible. â€Å"Mr. Asher, what are you doing up there?† Charlie nearly lost his balance and went over. â€Å"You can see me?† â€Å"Yes, sir, I certainly can. And I can also see that cinder block you're holding over your head.† â€Å"Oh, this old thing.† â€Å"What were you planning on doing with that?† â€Å"Repairs?† Charlie tried. How could Rivera see him when he was in soul-vessel-retrieval mode? â€Å"I'm sorry, but I don't believe you, Mr. Asher. You're going to have to drop the cinder block.† â€Å"I'd rather not. It was really hard getting it up here.† â€Å"Be that as it may, I'm going to have to insist that you drop it.† â€Å"I was planning on it, but then you showed up.† â€Å"Please. Indulge me. Look, you're sweating. Climb down and you can sit in my air-conditioned car with me. We'll chat – talk about Italian suits, the Giants – I don't know – why you were about to brain that sweet old lady with a cinder block. Air-conditioning, Mr. Asher – won't that be nice?† Charlie brought the cinder block down and rested it on his thigh, feeling his trousers snagging beyond repair as he did so. â€Å"That's not much of an incentive. What am I, some primitive Amazon native? I've had air-conditioning before. I have air-conditioning in my own van.† â€Å"Yes, I'll admit it's not exactly a weekend in Paris, but the next choice was that I shoot you off the roof, and they put you in a body bag, which is going to be sweltering on a warm day like this.† â€Å"Oh, well, yes,† Charlie said. â€Å"That does make air-conditioning sound a lot more inviting. Thanks. I'm going to toss my brick down first, if that's okay?† â€Å"That would be great, Mr. Asher.† Disillusioned with DesperateFilipinas, Ray was browsing through the selection of lonely first-grade teachers with master's degrees in nuclear physics on when she came through the door. He heard the bell and caught her out of the corner of his eye, and forgetting that his neck vertebrae were fused, he sprained the left side of his face trying to turn to see her. She saw him looking and smiled. Ray smiled back, then, out of the corner of his eye, saw the monitor with the photo of the first-grade teacher holding her breasts, and sprained the right side of his face trying to turn in time to punch the power button before she passed the counter. â€Å"Just browsing,† said the love of his life. â€Å"How are you today?† â€Å"Hi,† Ray said. In his mental rehearsals, he started with â€Å"hi,† and it just sort of burped out of him before he realized that it put him behind a beat. â€Å"I mean, fine. Sorry. I was working.† â€Å"I can see that.† Again the smile. She was so understanding, forgiving – and kind, you could just tell that by her eyes. He knew in his heart that he would even sit through a hat movie for this woman. He would watch A Room with a View AND The English Patient, back-to-back, just to share a pizza with her. And she would stop him from eating his service revolver halfway through the second movie, because that's just how she was: compassionate. She made a show of browsing the store, but two minutes hadn't passed before she made for Charlie's special shelf. Even the sign said SPECIAL ITEMS – ONE PER CUSTOMER, but it didn't say if that was a per-day policy, or one per lifetime. Charlie hadn't really specified, now that Ray thought about it. Sure, Lily had yammered on about how important it was that they adhere to the policy, but that was Lily, she might have grown up some, but she was still disturbed. After a short time she picked up an electric alarm clock and brought it over to the counter. This was it. This was it. Ray heard the back door open. â€Å"Will this be everything?† he said. â€Å"Yes,† said the future Mrs. Ray Macy. â€Å"I've been looking for one like this.† â€Å"Yep, you can't beat a Sunbeam,† Ray said. â€Å"That's two-sixteen with tax – aw, heck, call it two even.† â€Å"That's very nice of you,† she said, digging into a small purse woven from colorful Guatemalan cotton thread. â€Å"Hi, Ray,† Lily said, suddenly standing there beside him like some evil phantom who appeared out of nowhere to leech every potentially joyous moment out of his life. â€Å"Hi, Lily,† he said. Lily clicked some keys on the computer. Slowed down by his freshly sprained face, Ray wasn't able to turn before she'd hit the power button on the monitor. â€Å"What's this?† asked Lily. With his free hand, Ray thumped Lily in the thigh under the counter. â€Å"Ouch! Freak!† â€Å"I'm sure you'll enjoy waking up with that,† Ray said, handing the alarm clock to the woman who would be his queen. â€Å"Thank you so much,† said the lovely brunette goddess of all things Ray. â€Å"By the way,† Ray said, pushing on, â€Å"you've been in a couple of times, I was wondering, you know, because I'm curious that way, uh, what's your name?† â€Å"Audrey.† â€Å"Hi, Audrey. I'm Ray.† â€Å"Nice to meet you, Ray. Gotta go. Bye.† She waved over her shoulder and headed out the door. Ray and Lily watched her walk away. â€Å"Nice butt,† Lily said. â€Å"She said my name,† Ray said. â€Å"She's a little bit – I don't know – unimaginary for you.† Ray turned to the nemesis Lily. â€Å"You have to watch the store. I have to go.† â€Å"Why?† â€Å"I have to follow her, find out who she is.† Ray began to gather his stuff – phone, keys, baseball cap. â€Å"Yeah, that's healthy, Ray.† â€Å"Tell Charlie I – don't tell Charlie.† â€Å"Okay. So is it okay if I switch the computer from the UGLY Web site?† â€Å"What are you talking about?† Lily stepped back from the screen and pointed to the letters as she read, â€Å"Ukrainian Girls Loving You – U-G-L-Y, ugly.† Lily smiled, a perky, self-satisfied smile, like that kid who won the spelling bee in third grade. Didn't you hate that kid? Ray couldn't believe it. They weren't even being subtle about it anymore. â€Å"Can't talk,† he said. â€Å"Gotta go.† He ran out the door and headed up Mason Street after the lovely and compassionate Audrey. Rivera had driven up to the Cliff House Restaurant overlooking Seal Rocks and forced Charlie to buy him a drink while they watched the surfers down on the beach. Rivera was not a morbid man, but he knew that if he came here enough times, eventually he'd see a surfer get hit by a white shark. In fact, he sorely hoped that it would happen, because otherwise, the world made no sense, there was no justice, and life was just a tangled ball of chaos. Thousands of seals in the water and on the rocks – the mainstay of the white shark diet – hundreds of surfers in the water, dressed like seals, well, it just needed to happen for all to be right with the world. â€Å"I never believed you, Mr. Asher, when you said that you were Death, but since I couldn't explain whatever that thing was in the alley with you, didn't want to explain, in fact, I let it slide.† â€Å"And I appreciate that,† said Charlie, showing a little discomfort at drinking a glass of wine with handcuffs on. His face was candy-apple red from having been burned by the pepper spray. â€Å"Is this normal procedure for interrogations?† â€Å"No,† Rivera said. â€Å"Normally the City is supposed to pay, but I'll have the judge take the drinks off your sentence.† â€Å"Great. Thanks,† Charlie said. â€Å"And you can call me Charlie.† â€Å"Okay, and you can call me Inspector Rivera. Now, braining the old lady with the cinder block – just exactly what were you thinking?† â€Å"Do I need a lawyer?† â€Å"Of course not, you're fine, this bar is full of witnesses.† Rivera had once been a by-the-book kind of cop. That was before the demons, the giant owls, the bankruptcy, the polar bears, the vampires, the divorce, and the saber-clawed woman-thing that turned into a bird. Now, not so much. â€Å"In that case, I was thinking that no one could see me,† Charlie said. â€Å"Because you were invisible?† â€Å"Not really. Just sort of not noticeable.† â€Å"Well, I'll give you that, but I don't think that's any reason to crush a grandmother's skull.† â€Å"You have no proof of that,† Charlie said. â€Å"Of course I do,† Rivera said, holding up his glass to signal to the waitress that he needed another Glenfiddich on the rocks. â€Å"I saw pictures of her grandchildren, she showed me when I went in the house.† â€Å"No, I mean you have no proof that I was going to crush her skull.† â€Å"I see,† said Rivera, who did not see at all. â€Å"How did you know Mrs. Posokovanovich?† â€Å"I didn't. Her name just showed up in my date book, like I showed you.† â€Å"Yes, you did. Yes, you did. But that doesn't really give you a license to kill her, now does it?† â€Å"That's the point, she was supposed to be dead three weeks ago. There was even a death notice in the paper. I was just trying to make sure it was accurate.† â€Å"So in lieu of having the Chronicle print a correction, you thought you'd bash in granny's brains.† â€Å"Well, it was that or have my daughter say ‘kitty' at her, and I refuse to exploit my child in that way.† â€Å"Well, I admire your taking the high ground on that one, Charlie,† Rivera said, thinking, Who do I have to shoot to get a drink around here? â€Å"But let's just say that for one millisecond I believe you, and the old lady was supposed to die, but didn't, and that because of it you were shot with a crossbow and that thing I shot in the alley appeared – let's just say I believe all that, what am I supposed to do about it?† â€Å"You need to be careful,† Charlie said. â€Å"You may be turning into one of us.† â€Å"Pardon?† â€Å"That's how it happened to me. When my wife passed away, in the hospital, I saw the guy that came to collect her soul vessel, and wham, I was a Death Merchant. You saw me today, when no one else could, and you saw the sewer harpy, that night in the alley. Most of the time, I'm the only one who can see them.† Rivera really, really wanted to turn this guy over to a psychiatrist at the hospital and never see him again, but the problem was, he had seen the woman-thing, that night and another time on his own street, and he had seen reports of weird stuff happening in the City over the last two weeks. And not just normal San Francisco weird stuff, but really weird stuff, like a flock of ravens attacking a tourist in Coit Tower, and a guy who slammed his car through a storefront in Chinatown, saying that he had swerved to miss a dragon, and people all over the Mission saying that they'd seen an iguana dressed like a musketeer going through their garbage, tiny sword and all. â€Å"I can prove it,† Charlie said. â€Å"Just take me to the music store in the Castro.† Rivera looked at the sad, naked ice cubes in his glass and said, â€Å"Anyone ever tell you that it's hard to follow your train of thought, Charlie?† â€Å"You need to talk to Minty Fresh.† â€Å"Of course, that clears things up. I'll have a word with Krispy Kreme while I'm there.† â€Å"He's also a Death Merchant. He can tell you that what I'm telling you is true and you can let me go.† â€Å"Get up.† Rivera stood. â€Å"I'm not finished with my wine.† â€Å"Leave the money for the drinks and get up, please.† Rivera hooked his finger in Charlie's handcuffs and pulled him up. â€Å"We're going to the Castro.† â€Å"I don't think I can work my cane with these things on,† Charlie said. Rivera sighed and looked down on the surfers. He thought he saw something large moving in a wave behind one surfer, but as his heart leapt at the prospect, a sea lion poked his whiskered face out of the curl and Rivera's spirits sank again. He threw Charlie the handcuff keys. â€Å"Meet me in the car, I have to take a leak.† â€Å"I could escape.† â€Å"You do that, Charlie – after you pay.†

Influence Of Slope Aspects On Woodland Ecosystem Of Duhok Dissertation

Influence Of Slope Aspects On Woodland Ecosystem Of Duhok - Dissertation Example Studies have shown that position of a slope in an ecosystem affect the quality of organic material, soil chemistry, and nutrient cycling, largely; it affects the soil quality than even the type of bedrock beneath the soil (Yimer, Sting and Adelkadir 2006, p.95). Research that has been conducted on influence of topographical features on soils in southern Italy clearly demonstrate that soils originating from the same parent material, with the same vegetative covering and climate, with the only difference being the position of the landscape produced different and varied microclimatic conditions (Chen, Hsieh, Jiang, Hsieh and Sun 1997, p.230). In the northern temperate climatic zone, the aspect of a slope was found to be a huge influence of the microclimatic conditions of the area mainly influenced by the temperature levels (Coleman, Crossley and Hendrix 2004, p.312). This is because the amount of solar that area experiences will determine the levels of temperature and water in the soil, the inherent characteristics of the soil will be affected (Fu, Liu, Ma and Zhu 2004, p.48). In the Pinus laricio forests of southern Italy, the north-facing slope receives higher insolation and as a result, there is low moisture content that is also connected to the scanty vegetative cover and insolating effects of small vegetation (Gong, Chen, Fu and Wei 2007, p.1). Differences in the soil microbial activities offer the different type of plant species. These plant species depend on the soil moisture, root activities, temperature and organic matter that return to the soil through the litter that falls from the plants (Gong, Brueck, Giese, Zhang, Sattelmacher and Lin 2008, p.484). Studies have been carried out to determine the effects of climatic conditions on the soil and vegetation properties, however no studies have been carried to determine the influence of aspect in the soil and vegetation properties(Tewksbury and Lloyd 2001, p.426).

Blackberry outperform iphone in features and users Research Proposal

Blackberry outperform iphone in features and users - Research Proposal Example Objectives Some people say that iphone is far more superior to blackberry whereas others say that blackberry is superior to iphone in features and users. I strongly believe that blackberry has definite edge over iphone in number of users and better features and the major objective of this research is to establish my claims. Introduction/Background Apple Company’s iphone and Research In Motion (RIM)’s blackberry were the most popular mobile phones in the world currently. These products are currently engaged in fierce battle for supremacy across global markets. For example, Chinese and Indian markets are believed to be the most promising emerging markets in the world now because of the rapid economic growth happening there. Both blackberry and iphone are currently trying to establish in these markets. Both the products have its merits as well as demerits. BlackBerry functions as a personal digital assistant with address book, calendar, memopad, and task list capabilities whereas iphone has features like touch screen, enhanced internet browsing capacities, superior audio and video playing and capturing abilities etc. Bbalckberry can also functions as a portable media player and it is capable of sending and receiving Internet e-mail wherever mobile network service coverage is present, or through Wi-Fi connectivity. Methodology This research is intended to be conducted based on secondary data alone. Internet, printed articles, books etc will be used for collecting secondary data about iphone and blackberry. Both qualitative and quantitative data will be used in this research in order to establish my claims. This research will be completed within two weeks. The first 10 days will be used for collecting data and the last five days will be used for writing the final paper. It can be tentatively conclude that blackberry is superior to iphone. Literature review Black Berry phones have superior messaging features. Auto-text, auto-correct, text prediction, su pport for many languages, keyboard shortcuts, push notifications for email etc are some of the messaging features which are superior to iphone. Social networking sites such as Facebook, Twitter, Myspace, etc can be easily accessed through blackberries. Berry Messenger, Google Talk, ICQ, Windows Live Messenger, AOL Instant Messenger and Yahoo Messenger are the instant message services available in blackberries. Even though, iphone has some of these features, it cannot work as smoothly as blackberries. Blackberries have superior browsing speed and superior message handling facilities compared to iphones. Perhaps even more significantly, the iPhone fails to synchronize as well as the BlackBerry. When a BlackBerry user changes a calendar event or some contact information on his or her desktop computer in Exchange, the changes automatically appear on the BlackBerry. This makes keeping track of basic business information a snap because one never has to worry about acting on outdated data or manually updating one’s handheld. In contrast, the iPhone does not synchronize calendar and contact information wirelessly, which makes it less dependable for information ultimately stored on a server (Hendrickson, 2007) The iPhone’s functions can be easily accessed through a touch screen display using mainly by the finger commands. Moreover the picture quality (25,000 pixels per inch) of iphone is one of the bests among the new generation mobile phones. However, current blackberries have all these

The Legacy of the Prophet and the Society Assignment

The Legacy of the Prophet and the Society - Assignment Example In his book, Shadid notes that the face of Islam in the Middle East has changed from one perceived to be wary and violent to a peaceful one. Thanks to Islamic activists who have undergone great transformation helping the poor and providing solace through their social activism. Hashemi also records that the argument in The Legacy of the prophet was mainly based on the change in political Islam. This political change represents the modern Islam and is characterized by advocacy for democracy and non-violence. These Islamic movements have demonstrated a shift from the older militant process to a more democratic process. The modern Islam advocate for moral Islamic commitment and community loyalty, economic justice and a place for women in society, and advocate for a state governed by Islamic Sharia. These would translate into a modern society. Kurzman notes that there are three models of Sharia: Liberal sharia, silent Sharia and interpreted sharia. Some of the issues raised in The Legacy of the Prophet are representation of the models presented by Kurzman. This is particular with the â€Å"interpreted sharia†. According to the model, sharia is welcome to interpretation. The fact that modern Islam advocate for democracy and liberalization links them to â€Å"interpreted sharia† model. Model is seen as liberal allowing for re-interpretation of sharia. The model also depicts sharia as divine. This aspect is evident in the modern Islams when they advocate for a state governed by Sharia which is divine  

Court Administrator and his Problems in Organization Problems Essay - 1

Court Administrator and his Problems in Organization Problems - Essay Example Thus, I would suggest that there be a secret balloting to identify the decisions of the judges on certain matters then, a decision can be reached. One way to improve the communication throughout the organization is first identifying what type of communication does the organization need and prefer. There should also be activities that would be able to help the employees to release their stress. There are several activities that can be done, like, sports events. There can also be a welcome party for the incoming judge and a farewell for the outgoing. This can promote camaraderie among employees. I can solicit suggestions and ideas from Judge Cortez on what she thinks regarding the disputes among the employees. These are valuable insights that might be able to provide the court administrator with an initiative on how to solve the problems. For Judge Cortez’ successor, these proposals can be made so that s/he would be able to start or continue the reconciliation efforts among the offices of the court. 1. In a general way, discuss both the merits and difficulties posed by this case management approach. Relate your response to the general advantages and disadvantages of both the individual and the master calendar systems. One of the greatest advantages of the individual calendar system is that it is easier to pin down delay. One can easily match up to judges’ dockets to find out what are the developments of the cases, whether it is moving or not. On the other hand, the master calendar systems’ highlight is that judges who specialize in a specific phase of the proceedings can be allowed to handle such. Although both systems also carry disadvantages like for the individual calendar system the speed of the disposition of cases depends on the judges. For the master calendar system, the disadvantage lies in the lack of the way to see where the delay is.  

Bussiness Ethics Essay Example | Topics and Well Written Essays - 2250 words

Bussiness Ethics - Essay Example Although, some manufacturers made deliveries to IKEA, mostly at night to avoid being seen, IKEA thought of other strategic options to counter this problem, and one among them is outsourcing. This made IKEA to go scouting abroad for manufacturers and Kamprad entered into contracts with number of factories in Poland, thus ‘seeding’ more outsourcing. It was this early decision of Kamprad to seek least expensive alternatives to domestic manufacturing of the products turned out to be a more profitable avenue for IKEA to take. As, this outsourcing strategy reduced the costs of production, it is able to offer affordable or cheap prices to the customer, thereby bringing in more customers. â€Å"IKEA currently works with 1,300 suppliers in 53 countries, but Kamprad made the pioneering decision to source furniture from communist Poland as early as 1961. Since manufacturing costs were 50% lower in Poland than in Sweden, his decision looks brilliant in hindsight.† (Barthelemy 2006). Importantly, IKEA continued as well as extended its outsourcing strategy to other countries particularly 1980’s and 90’s, particularly to Asian countries like India, Ch ina, Pakistan, Philippines, etc, where they can access cheap labour. Although, outsourcing to these countries gave IKEA a cost-effective option, it also led to the rise of ethical issues and controversies, both from the economic as well as political perspectives, thereby making or even forcing IKEA to come up with Corporate Social Responsibility (CSR) based activities. IKEA outsourced to the Asian countries many of its manufacturing processes including making of carpet, rugs, wicker baskets, etc. That is, in starting from 1970s and more prominently from 1990’s, they found many local manufacturers cum suppliers, who would manufacture the products and supply to them with IKEA label. This turned out to be a productive and profitable option, as IKEA was able to get good productivity for cheaper prices, when compared to the

What is the role of social media in the field of journalism Annotated Bibliography

What is the role of social media in the field of journalism - Annotated Bibliography Example Processing Culture: Cognition, Ontology, and the News Media Processing Culture: Cognition, Ontology, and the News Media. Sociological Forum, 25(4), 824-850. doi:10.1111/j.1573-7861.2010.01214.x The article discusses how U.S. civilians perceive and react to news from diverse social media mainstreams. Mainly, this encompasses how a person psychologically intercepts, interprets news and assessing relayed information to result to a certain conduct once intellect undergoes adequate stimulation. This is in a move to establish desired order in unpredictable social world in order to ascertain what is genuine and factual in all media circles. The author outlines how people have adapted to the use and function of online social media in journalism in this 21st century. He claims that people are bemoaning and condemning the reduction of journalistic material at the same time analyzing the expanding recognition of social media in today’s era. In addition, he argues that the use of social media like blogs as today’s means of communication is a strong and clear indication implicating the changes and transformation in journalism. The author concludes that there is no need in advocating and shielding journalism old ways of news broadcasting because consumers adores besides being preoccupied with the new digital upstarts that is deflating the old media. This article claims that twitter as well as micro-blogging has been dominating contemporary social transmission of information especially during crises both at international and national levels. Oh, Agrawal and Rao (2013), despite acknowledging how twitter together with blogging have played a significant role in relaying information during varied crises contend these sites pose a potential danger. This is in terms of the relayed information’s reliability due to lack of valid source though the current generation seems not to care but continue to rely on it. This is contrary to the old fading journalism whereby

According to Weart (2003), global warming has been accelerating since 2005, and is further expected to increase if the environment is not taken care as would be expected particularly if there is no reduction of emission from burning fossils fuels such as coal and oil. Additionally, the rise in average have been confirmed as having far reaching effects on the general climate pattern across the world, and to human beings as well. As such, global warming has dire consequences on health, wildlife, weather patterns and glaciers and sea levels. Firstly, global warming has continuously led to high temperatures which translate to increased droughts and wildfires, heavier rainfall and numerous hurricanes across the world, and especially in Europe and Asia. According to Houghton (2008), the frequent occurrence of hurricanes that are more powerful and dangerous are as a result of warmer waters in the ocean that pumps energy into tropical storms that are potentially destructive, a situation that make easier to experience more complicated hurricanes in future due to flooding and soil erosion. Moreover, global warming has increased drought and wildfire due to greater evaporation that has been witnessed during summer, a situation that directly or indirectly leads to wildfires. Scholars associated to climate change and weather patterns have argued that when temperatures are warm they are likely to lead to heavier rainfall. Secondly, global warming has directly led to health consequences. Basically, the presence of hotter weather facilitates deadly mosquitoes to travelling for greater distance and the availability of carbon dioxide in the air makes a conducive environment for the growth of airborne diseases such as asthma and allergies. Additionally, the presence of more frequent and serious heat waves

Position Supporting Stem Cell Research Essay Example for Free

Position Supporting Stem Cell Research Essay Cells that can make a distinction into a variety of cell types are called stem cells and comprise embryonic stem (ES) cells and adult stem cells. Since ES cells can turn into a new organism or can differentiate into any tissue type, they are said to be â€Å"totipotent.† Adult stem cells, conversely, as they cannot turn into any type of tissue, are said to be â€Å"pluripotent.† For instance, bone marrow stem cells can turn into red blood cells, T-lymphocytes, or B-lymphocytes, however not muscle or bone cells. Nerve stem cells can as well turn into different types of nerve tissue. Stem cell research attempts to engineer tissues from the bodys stem cells to replace defective, damaged, or aging tissues. In 1998, scientists were capable to grow human ES cells indefinitely. Since then, researchers have performed stem cell experiments on mammals and have had some achievement in repairing spinal chord injuries in mice. Since scientists cannot use federal funds to carry out research on embryos, private corporations, most particularly the Geron Corporation, have funded ES cell research. Geron, awaiting possible ethical concerns, appointed its own ethics advisory board. The Clinton administration sought to loosen the interpretation of the ban on embryo research to permit the government to sponsor research on the use of ES cells once they were available. President G. W. Bush had made the decision to permit use merely of about sixty existing cell lines, and not the production of embryonic cell lines particularly made for the purpose of use for stem cells[1]. The majority of the stem cell procedures proposed to date would employ the ES cells from embryos formed by couples in fertility clinics. In the United States, thousands of embryos are discarded each year as IVF couples cannot use all of their embryos. A couple may make three-hundred embryos in an attempt give birth to one child. One more approach to stem cell research suggests that researchers make embryos for scientific and medical purposes. This approach, recognized as therapeutic cloning, or somatic cell nuclear transfer (SCNT), engrosses transferring the nucleus from a cell in a persons body into an enucleated egg[2]. The ES cells from this new embryo would match the tissue in the persons body, therefore avoiding the potential tissue rejection problems that might occur in stem cell therapy. The potential of stem cell research is huge, for the reason that so many diseases result from tissue damage. Stem cell research could bring about advances in treating paralysis, diabetes, heart disease, pancreatitis, Parkinsons disease, liver disease, arthritis, as well as many further conditions. [3] Thus human pluripotent stem cell research is very important as firstly it propose help in understanding the actions that take place during normal human development. The understanding of human cell development could make possible further understandings regarding how abnormalities such as cancer occur. Secondly this research helps us to find out why some cells turn into heart cells whereas other cells turn into blood cells. Although it has been previously recognized that a gene turning on and off is central to cell development, however it is not recognized what makes these gene turn on and offstem cell research will most probably give a possible explanation. In a realistic sense this could make possible further understandings of cell development abnormalities. Thirdly pure samples of specific cell types could be used for testing different chemical compounds so as to develop medicines to treat disease[4]. This would make more efficient the process of medical testing in order that merely medicines that have a helpful effect on cell lines would be tested on animals and humans. And most significantly this research could be very helpful for cell transplantation therapies. Theoretically, stem cells could be grown into replacements for diseased or destroyed cells[5]. This would permit medical science to get to the bottom of diseases of organ failure for instance diabetes as well as neurological disorders for instance Parkinsons disease. The main protest to this promising research has to do with the source of ES cells. ES cells can be acquired from aborted embryos, embryos remaining after infertility treatments (IVF), embryos created only for research by IVF techniques, and from SCNT techniques (that is therapeutic cloning)[6]. To get ES cells, consequently, one have to either create embryos that will be used, manipulated, or destroyed, or one have to get embryos leftover from infertility treatments. However here is where the abortion debate resurfaces, as these techniques would engross treating embryos as mere things or objects and would not give embryos the esteem they deserve, as said by some critics. That is to say that a proper, fair and realistic account of what comes out of the freezer is a 5-day-old ball of about 150 cells, and of that the researchers will want to use about 30. What comes out of the freezer is unquestionably human tissue however it is not human. That ball of cells has no hope at all of becoming a human being without further intervention. One must not confuse the existence of a chance of becoming a human being with actually being human. The tissue can be likened to organs taken from a lately deceased person for transplant. Neither the organ nor the tissue is dead; it is human tissue but it is not human. One may say the same of sperm, for instance, every sperm must be protected that is available for the reason that it might, under circumstances where other things have to happen, become a human. That is practically the same thought. What has to happen there is that the sperm has to meet with an egg to fertilize that egg, which then has to be looked after. What has to happen with a 5-day-old ball of cells in which the egg and sperm have previously met is that it after that has to be implanted in a woman and stay there for nine months. In both cases nothing is going to happen unless other things are brought into play. It is a very strong view that it is not being talked about a human, rather about human tissue that will with the intervention of others, and only with the intervention of others, has the chance of becoming human. A parents right must be supported to demand that any of these untouched fertilized eggs be left untouched for afterward use or not be used for research. Very few, if any, parents who have had the advantage of the IVF program would refuse the chance for spare fertilized eggs to be used. They themselves turned to the wonders of science to give them what apparently nature was otherwise going to deny them, those who through the wonders of science have had what must have been their greatest dream realized would definitely not deny the chance for science to make better things for others. After all, how many fertilized eggs at varying stages of development were used in the IVF programs to get to the point where one could have a successful IVF program? [7] Some supporters of this bill do not deny where one is now with the science. He just wants science to have the opportunity to take him to further and better places. One cannot say that there is no practical application of this now, so not do the research. That is the equal of saying to a child that you are not permitted to swim in the pool until you have learned to swim. How can one possibly refuse to do research on the basis that he does not have the researchers outcomes? One can not get those outcomes until he proceeds with the research. So, again, one must be very much on the side of proceeding with stem cell research. Some of the objections which have their foundation in a religious view held by their proponents. Living by a decent set of values is far more vital than defending the doctrine of one church over another. If you lead a good life and if there is a kingdom of heaven you will be welcome into his or heaven. Your religion is your business and no-one elses. When you make your religion an issue, you drag it into the political domain and you tarnish it. It follows that we attach very little importance or interest to arguments over religious dogma. Similarly, we do not turn to the state to legislate for one religious view over another. Without doubt, we can clearly see the risks of adopting a view that your religion is the right one and the rest of the world must be converted. This point is quite simple: each to his own religion. If you say to one that doing something is against Gods will, then he will respond by assuring you that, if God is annoyed, God will punish whoever has done that thing. The state should never be used as Gods enforcer. Over the years, as we have been approaching 50, we can assure you that we have every confidence in Gods capability to settle accounts. It has not been our experience that he or she usually waits until you are dead. Numerous people who have done the wrong thing have met their maker in a practical sense while they were still alive[8]. In brief, we are talking about fertilized eggs that are in the freezer. They have not the slightest chance of becoming human unless they are accepted by the mother to be carried for 9 months. We are talking about fertilized eggs where that is not the case. The outcome is that they are either going in the bin or going to be used for the betterment of mankind. My other proposition is that we cannot now say whether the science is good or bad. We do not know where the science is going to take us. Science of itself is not fundamentally good or bad; it is what we do with it that will make that case. We have to understand that the benefits of this research may take years to come. That merely makes us say: start more quickly. We simply ask those who, due to their religious beliefs, have a very authentic concern regarding this bill to accept that they are entitled to follow their religious beliefs; they are not entitled to demand by legislation that everybody else does the same.

The Most Awesome Day in My Life Essay Example for Free

The Most Awesome Day in My Life Essay While sitting on the loosing bench in San Ignacio Town feeling like a dog that was dis-owned by owner after we lost our volleyball game to the most outstanding team of the day, my life just gat brightened in a split second like a lightning striking some energy into to me when I saw the most beautiful woman I have ever seen in my life. My eyes glued to her as she was slowly walking in my direction with a pair of long legs that lead straight to heaven and walking as if she was going up for miss universe. My jaws fell to the ground as I starred on her like I have never seen a woman before, she moved very elegantly and the way she moved while I was staring at her a second felt like a hour wile looking at this priceless prized position coming my way. She stood five feet nine inches off the ground with long, beautiful and smooth hair resembling a horse’s tail while covered with in flawless smooth silk for skin. Her eyes were like looking into two diamonds as they slowly moved around as she moved elegantly to buy her soda. It felt like everything and everyone around me froze for that moment to just acknowledge her presence as was slowly approaching. Her narrow smooth face that was decorated with a sharp nose, pretty pink lips that look like strawberry and a perfect set of teeth that would have any dentist dying to get his hands on them glittered as she slightly spread her lips to smile and her set of pearls in her mouth glittered. The skin on her face was so pretty and clean it was like if they were allergic to zits. She gat a bit closer to me and I tried to stand up to greet her the time of the day but I couldn’t because my knees felt so weak and was shaking like leaf I couldn’t have done nothing but sit there. She took a few more steps closer and my heart was pounding as if she was walking on them.

Quantum Optical Model Nonintegrability Quantum Fluctuation

Quantum Optical Model Nonintegrability Quantum Fluctuation Nonintegrability and quantum fluctuations in a quantum optical model Nilakantha Mehera and S. Sivakumarb Abstract Integrability in quantum theory has been defined in more than one ways. Recently, Braak suggested that a quantum system is integrable relating the number of parameters required to specify the eigenstates and the number degrees of freedom (both discrete and continuous). It is argued that the dependence of uncertainty product of suitable operators on the atom-field interaction strength is distinctly different for the integrable and nonintegrable cases. These studies indicate that the uncertainty product is able to identify the nonintegrable systems from the integrable ones in the context of this new definition. Introduction A classical dynamical system with n degrees of freedom (DOF) is integrable, Liouvillean integrable to be precise, if there are equal number of suitable constants of motion (COM) that have vanishing Poisson bracket among themselves and with the Hamiltonian1.. Otherwise, the system is nonintegrable. While this definition is based on a sound mathematical footing, the situation in quantum dynamics is not very clear, essentially arising from the difficulty in defining or identifying DOF in quantum theory2. One possibility is define integrablity by the existence of sufficient number of observables which commute with the Hamiltonian and pair-wise commute among themselves. However, this is wrought with difficulties as it may not be possible to arrive at classical limits of some quantum systems. One such example is the case of a single two-level atom interacting with a single mode of the electromagnetic field. The former is a discrete DOF (finite dimensional Hilbert space) and the later is a continuous DOF (infinite dimensional Hilbert space). While the continuous DOF, namely, the electromagnetic field, has a proper classical limit, the two-level atom does not have a suitable classical limit. According to a new definition introduced by Braak, a system is integrable if the number of parameters required to specify the eigenstates of the Hamiltonian is equal to the sum of the number of discrete DOF and continuous DOF2. This definition does not involve the existence of constants of motion, though all such cases are covered by this definition. In this new definition of integrability, some of the nonintegrable systems based on the Liouvillean definition become integrable. A simple example of such a system is the Rabi model describing the interaction between a two-level atom and a single mode of the electromagnetic field with Hamiltonian3; (1) Here, are Pauli matrices, is the atomic transition frequency, () denote the annihilation (creation) operators of field with frequency. is the atom-field coupling constant. This Hamiltonian has only one COM, namely itself. Since there are two DOF, the field and the two-level atom, the Hamiltonian is nonintegrable in the sense of Liouville. However, exploiting the parity symmetry in , the system has been shown to be integrable2. Another interesting case is the rotating wave approximation of , yielding the well known Jaynes-Cummings model4,5: (2) This Hamiltonian has two COM, the Hamiltonian itself and the operator for the number of excitations . Existence of these two COMs renders the Hamiltonian integrable. The eigenstates are labelled by two parameters,an integer n corresponding to the number of excitations and the total energy. Also, both the Hamiltonians and exhibit level-crossings of the eigenvalues as the interaction strength g is varied, which is an indication that the models are integrable2. Level-crossing refers to the phenomenon where in the eigenvalues depend on the interaction strength g in such a way that the eigenvalues corresponding to two different eigenstates become degenerate at a specific values of g and reverse their order for other values of g. Nonintegrable Model : An interesting modification to to make it nonintegrable is to break the à ¯Ã‚ Ã… ¡2 symmetry by adding and this leads to; (3) Within the scope of the Braak’s definition of integrability, this model is integrable only when ÃŽ µ is an integral multiple of ω/2. This is also borne out by the existence of level crossings as shown in Fig.1. This criterion is sufficient for nonintegrability. We assume resonance . For the results presented here, it is assumed that =1 and ω=1. In Fig. 1, the absence or presence of level-crossing indicates respectively the nonintegrability or integrability of the Hamiltonian . Fig.1.Energy level (En) as a function of g for different à °Ã‚ Ã…“â‚ ¬. Level crossing occurs if à °Ã‚ Ã…“â‚ ¬=0 and 0.5 indicating integrability. No level crossing if à °Ã‚ Ã…“â‚ ¬=0.3, indicating nonintegrability. Inset shows larger view of level crossing. A pertinent question in this context is to know those features that distinguish a nonintegrable atom-field system from an integrable one. One answer to this query appears to be that uncertainty product of a pair of suitably defined operators show markedly different characteristics. Since the system is nonintegrable, it is formidable to construct an analytical solution. Therefore, extensive numerical experimentations have been carried out and the results are presented here which support the claim stated above. Nonintegrability being a feature of the Hamiltonian, it is natural to expect that the eigenstates carry signatures revealing this feature. To explore this, we define two self-adjoint operators of the two-level atom, , , where () is the atomic raising (lowering) operator. The commutation relation implies that the value of the product of uncertainties lies between 0 and 1/2. The uncertainty relation of above operators is . whereis expectation value in any eigenstate. In Fig. 2, the uncertainty product is plotted as a function of the atom-field interaction strength for different values of à °Ã‚ Ã…“â‚ ¬: à °Ã‚ Ã…“â‚ ¬= 0, 0.5 and 1.0 corresponding to the integrable case and a few other values of à °Ã‚ Ã…“â‚ ¬ corresponding to nonintegrable case. It is seen that as the parameter g is increases, the uncertainty product attains its maximum allowed value of  ½ for the integrable cases. On the other hand, for the nonintegrable cases the uncertainty product falls below the limit of  ½. In order to establish that the uncertainty product is very sensitive to the nature of the the integrable and nonintegrable cases, the plots corresponding to values of à °Ã‚ Ã…“â‚ ¬ very close to integrable cases have been chosen. Fig.2.Uncertainty product () as a function of the atom-field coupling constant g. Different plots correspond to different values of à °Ã‚ Ã…“â‚ ¬: integrable cases: à °Ã‚ Ã…“â‚ ¬=0, 0.5 and 1.0, nonintegrable cases: à °Ã‚ Ã…“â‚ ¬=-0.01,0.01, 0.49,0.51,0.2 and 0.4. In any plot, the uncertainty is plotted for the eingenstates corresponding to the first fifty eigenvalues. For instance, in the second row in Fig. 2, the sudden change in the nature of uncertainty product as à °Ã‚ Ã…“â‚ ¬ assumes values 0.49 (nonintegrable), 0.5 (integrable) and 0.51 (nonintegrable) respectively are shown. In order to bring out the features more clearly, the probability distribution of the uncertainty products in different eigenstates are shown in Fig 3 corresponding to the respective figures in Fig. 2. The sharply peaked probability distribution indicates integrability. Fig.3. Probability distribution of the uncertainty product for all the eigenstates for a particular value of g, chosen to be 1.2 here. Any higher value of g yields the same results. Summary Identification of nonintegrability in an interacting atom-field system is possible by the concentration of uncertainty product near a particular value as the atom-field interaction strength is increased. This feature seems to be related closely to the nonintegrability, also supported the absence of level crossings. This feature has been found to be able to identify nonintegrability in many other models that have been studied. In essence, suitable uncertainty product is able to identify nonintegrability, which is often difficult to establish analytically or numerically. Nevertheless, our analyses raise some important questions for which answers are to be found: Is it possible to arrive at the existence of this feature using only the definition of nonintegrability used here? Given a Hamiltonian, how to identify the correct observables whose uncertainty product will concentrate as the interaction strength is increased? How to extend this idea if the number of atoms is larger? References: M.V. Berry and M. Tabor, Proc. R. Soc. A 356, 375 (1977). D.Braak, Phys.Rev.Lett. 107, 100401(2011). I. I. Rabi, Phys.

rebeldol Essay on Nora’s Rebellion in Ibsens A Dolls House

Nora’s Rebellion in A Doll’s House  Ã‚  Ã‚  Ã‚  Ã‚   The central theme of A Doll’s House is Nora’s rebellion against society and everything that was expected of her. Nora shows this by breaking away from all the standards and expectations her husband and society had set up for her. In her time women weren’t supposed to be independent. They were to support their husbands, take care of the children, cook, clean, and make everything perfect around the house. Nora’s first rebellion was when she took out a loan so that she could pay for her husband, Torvalds medical treatment. It was against the law for women to take out a loan without their husbands consent. When she did this she proved that she wasn’t as submissive and helpless as Torvald thought she was. He called her a "poor helpless little creature". A perfect example of Torvalds control and Nora’s submissiveness was when she got him to re-teach her the tarantella.

Arrowsmith Essay -- essays research papers

Arrowsmith is a classic American novel written by Sinclair Lewis. Lewis wrote this book in the early 1900’s as a current outlook on the world of science in that time. The main theme it focuses on is commercialism and its effect on science. During this time period there were many advances in the field of medicine; everyone was racing to find the cure to deadly diseases and then patent it and profit off it. Helping humanity was more of a business than a service to the human race as doctors and institutes became more and more capitalistic. Like a business trying to maximize its profit, many doctors and scientists cut corners and guessed at many things so they could get their products or methods on the market as fast as possible. However, there were a few scientists who stayed strictly devoted to their science, not letting money, glory, and success corrupt them. Scientists such as this despised commercialism and held contempt against the other doctors and scientists who fell into that system of capitalism. The book follows the life of Martin Arrowsmith, a scientist who is torn between pure science and commercialism. He wants to be a true scientist but he is pushed into commercialism by everyone he meets, except for a select few. Among the few is Max Gottlieb, who is Martin’s model for everything a true scientist should be. Gottlieb is a bacteriologist who is completely against the capitalist values of commercial doctors and scientists; he devotes himself religiously to his science, and he believes in being completely thorough and not guessing or accepting things without completely understanding them. Terry Wickett, a disciple of Gottlieb’s, holds all the same values and attitudes as Gottlieb toward capitalism and commercialism. He helps Martin break away from commercialism, and become a true scientist. Another person who greatly helps Martin in his life is his first wife, Leora Tozer, who stands by and supports Martin no matter what. She devotes herself to Martin as much as Gottlieb devotes himself to his science. She supports him in whatever decision he decides to make, she helps and comforts him in his times of need, and she remains completely loyal to him at all times, even when he is not completely loyal to her. The story starts with Martin Arrowsmith as a medical student at Winnemac University, where he was first introduced to commercial science and pure s... ...from the Plague. What is ironic about this is that this pure science tends to benefit humanity more than commercialism science in the long run. The notion that one significant improvement over a long period of time is better than a series of failures and half-successes is drowned out by the propaganda of commercialism. Pure science produces methods and medicines that are certain. They have been thoroughly tested and proved to be successful, as opposed to the medicines produced by commercial scientists. While they produce more, they are not certain as to what effect they will have. They hope that if their product works in one situation, it will work in every situation. However, commercial science does have positive points as pure science has negative points. While pure science is more certain it is also much more long term. Commercial science gives immediate care and help, despite how much it may actually help. Pure science is presented as something that looks toward and works for the future, while commercial science deals with what is happening at the moment, but commercialism hinders pure science so much that, in effect, it may be bringing about the destruction of its own future.

Low Birth Weight Essay -- Medicine Medical Pregnancy Essays

Low Birth Weight Low birth weight (LBW) is a term used to describe infants that are born under 2, 500 grams, or less than five pounds eight ounces. This is a disorder that plagues certain races, age groups, and the poor. Seven percent of all infants who are born in the United States are born too small and eleven percent are born too soon ( Behrman). There are many risk factors that put a mother at risk of having a low birth weight baby, as there are many complications early and later in life for the child. There are certain women who are more likely to have a child who is born extremely under weight. These influences can be ethnic, environmental, and genetic. Recent studies have shown that thirty to forty percent of low birth weight children are born into African American families. In fact, black women are two times more likely than are white women to have low birth weight babies. If a woman does not gain very much weight during her pregnancy, then she is more likely to have a child with LBW. A small or petite woman is also more likely to produce very small children. The first born child in a family is also more at risk. Women who have had previous low birth weight children, low birth weight themselves, and or genetic disorders are all at higher risk of low birth weight (Behrman). Female babies are more likely than boys to be smaller at birth. Children who are born premature, or before thirty-seven weeks are more likely to have LBW. If a woman's placenta is irregular, then that could also inhibit the growth of the child. This is because of feeding difficulty while in the womb (Campbell). The age of the expectant mother is another deciding factor about whether the child will be of LBW... ...nitoring stress women can greatly reduce their chances of having children who suffer such great obstacles. Prenatal care is also very important. This small segment of our population deserves a fighting chance. Works Cited: Behrman, Richard E, and Patricia Shiono.

Thematic Analysis on the Book American Buffalo by David Mamet

A buffalo accepts minimum from the society and gives the maximum-its food is grass (unless you feed something special) and the finished product that you get is milk! The junk store shown when American Buffalo opens, doesn’t inspire much. Normally, when the curtains are raised, the opening scene/set is supposed to be the best, highly impressive, to create a lasting impression with the audience. The secondhand â€Å"antique† store run by Don Dubrow nevertheless, kindles curiosity. The stage is filled with lots of junk. It is ‘easy’ to create neat and clean or fascinating sets.A jumble set needs so much imagination to do. For example, a big overflowing dustbin prominently kept at the stage evokes as much curiosity as the big flower-vase full of colorful flowers. It evokes immediate enthusiasm in the minds of the spectators, â€Å"Why it is there on the stage at this initial stage of the drama? † The opening dialogues go to the credit of Don who is deliv ering a business discourse to Bob, inviting his attention to the promised deals and the necessity to stick on to it. Bob was busy with not so healthy and socially acceptable ideas to get rich quick.Bob apologizes, but Don speaks with a frustrated note at his friend’s temporary betrayal. Don retorts, â€Å"Don’t tell me you’re sorry, I’m not mad at you. † This observation speaks about the sincerity of Don to bring his friend to the right track, by involving him in the respectable business of junk dealings! Filling the stage with the junk in such voluminous and vast quantity is not the easiest of the things to do. Clive Barnes (writing for the New York Times) called the Broadway set â€Å"astonishing† and described it as â€Å"an agglomeration of trash that must have taken a team of assistants months to acquire.† (American†¦) Out of that confusing and unclassified dump, David Mamet tries to find the essential needs for a dignified life. The junk yard is the not the final destination for those articles. They rather wait for a new beginning—yet another lease of respectful life! The theme as conceived by Mamet, has some hidden agenda as for the welfare of the society. He has strange ways of propounding how to achieve his objectives! American Buffalo received intense critical attention, for it set the critics thinking and disturbed their psyche.What they saw on the stage was not an ordinary effort as depicted by an ordinary story. The emotional highs and lows of the characters were realistic as per conditions obtaining in a big chunk of the American Society. David Mamet used the lowest of the language, the meanest of the vocabulary, to say his truth. He was bold in his approach, but no so beautiful and refined. But where is refine ness in the real-life situations that he was explaining? But the nods and appreciation that he secured for the plot and for his characters must be from those who have experienced such situations, either with or without success.David Manmet doesn’t value victory or defeat much. He sees the truth in the permanent efforts. The untiring ones! His thematic approach to the language and expressions he used in the play is with a definite purpose. He could have written the dialogues in ‘King’s English’, but he preferred the idiosyncrasies and the latent humor of everyday speech of an average individual. Such characters responded and reacted to the routine situations in an ordinary but emphatic way. They expressed their opinions in a crude manner, by ‘keeping the essential dignity’ of their position in the society.Every individual lives his life along with certain ambiguities, which he carries as his luggage, when he is unable to solve them. He however has a hope that one day he will be able to solve them, and will achieve a problem-free state. Reading a play is one thing, and looking at the performance, when many characters â €˜read’ the play in accordance with their acting abilities, is another matter. The script, when you read may confuse you, may keep you less-inspired, you may feel that you are making desperate efforts to go through confusing paragraphs and sentences.But when the characters do their sincere job of pronouncing them on the stage, David Mamet proves to us that he is right. He has judged their spirits and caught their moods right, with those appropriate utterances, what if they are half-thoughts and obscenities. He has showed and depicted the reality of obscenity, because you find it very much prevalent in the vocabulary of the society about which he is writing. So, what harm is there in calling the spade a spade? The incident shown about three crook’s planning to steal a coin collection in the name of â€Å"good business† is right according to their level of thinking.(It is better than stabbing an individual to rob his wealth or cheat a bank with fraudulent ideas ) That is the stage of their progression in life. They are able to offer justification for their actions as per their own perfected reasoning. Whether the society accepts it or not is another matter. But they have no confusion about their objective. The characters of David Mamet have a particular level of existence. You can’t pass judgment on them by sitting on the ivory tower. To know them, you need to reach their level. Understand their real-life situations and put you in their shoes!They do, what they do, not out of pleasure; but out of sheer necessity of existing in this world. Therefore, the seemingly inarticulate utterances yield a rhythm found in few other playwrights' work. â€Å"Part of the fascination of the play,† wrote Women's Wear Daily's Howard Kissel, lies in â€Å"noting how the same banal language takes on different colors as we perceive the changing relationships† between the characters. (American†¦) To maintain friendship and business tog ether requires lots of understanding. The beginning seems to be good, but what really matters is maintenance of the relation ship.Business world is not always the domain of ethics. The fundamental principle and the goal in business are profits, success and self-interest. The play makes good beginning as for the combination of business and friendship but by the end of the play, the edifice of friendship collapses, and self-interest hoists the flag of victory. The theme of any story always tells something about the author, even when the author makes conscious efforts to avoid it. Recollections of author’s past appear in some form or the other.May be some dialogues, situations, trials and tribulations, duty and beauty of the characters—somewhere between the interactions of the character it surfaces in a subtle form. David Mamet had a difficult childhood. He was born in Chicago, and was raised in a Jewish neighborhood. His father being a labor attorney, discussion about la bor problems must have been commonplace. Mamet has learnt and depicted the anger, frustration and slang of American youth and men very well and this can be learnt and captured in the printed page only through direct experience and exposure to situations.David Mamet introduces a unique theme in American Buffalo-the judicious use of sabotage. They say, all is fair in war and love. Mamet adds one more category to this-business wisdom (when reduced to its basest form. ) He was appreciated for his ability to find equation with the common man through this play. Their slang became his weapon of success. His characters rarely speak full sentences, but what they utter has the telling effect. You nod in approval, as it appeals to you emotions. The three main characters, the low life thugs, succeed in taking potshots at the American way of life and its business ethics.The bricks of foundation of America are dispossession of the land from the former owners and genocide of the local Indian popul ace. â€Å"The drama and conflict among the characters is intense in a very disturbing way. This is a play that makes you very uncomfortable about the way that people relate to each other and challenges your hopes that values like friendship and honor are greater than the drive to get a bit ahead no matter who you step on in the process. † (Theatre†¦) Conclusion: American Buffalo is a common man’s drama, in common language, dominated bycommon characters, but written by an uncommon author. ========== References Cited: Article: Theatre Card: American Buffalo By David Mamet . †¦ www2. netdoor. com/~campbab/theatre/buffalo. html – 10k – Retrieved on October 10, 2007.

More broadly, when a car such as the Beetle or Thunderbird is redesigned or given a raising for the modern car buyer, what are the design pitfalls and concerns, and specifically, what kind of market research should be conducted to ensure that the pitfalls are avoided?When a car such as the Beetle or Thunderbird is redesigned for the modern car buyers, the most relate issue is safety. Some of the redesigns want to reciprocate the demands of consumers, however ignore the safety issues. In my opinion, the Primary research is research that design and conduct by ourselve s. Several tools are available to the market researchere.g., broadcast questionnaires, phone surveys, observation, and focus groups. Research will often help us scale down risks associated with a new product, but it cannot take the risk away entirely. It is also important to ascertain whether the research has been complete.

Advances in Modern Irrigation Systems Essay

ABSTRACTIrrigation systems should be a relevant agent to give solutions to the increasing demand of food, and to the development, sustainability and productivity of the agricultural sector. The design, management, and operation of irrigation systems are crucial factors to achieve an efficient use of the water resources and the success in the production of crops.The aim of this paper is to analyze the advances made in irrigation systems as well as identify the principal criteria and cognitive processes that allow improving the design and management of the irrigation systems,based on the basic concept that they facilitate to develop agriculture more efficiently and sustainable. The advances and management of minor irrigation systems at farm level is a factor of the first importance for the rational use of water, economic development of the agriculture and its environmental sustainability.They lack the complete control agents needed for biological pest control andlarger quantities o f sprays have to be utilized as pests rapidly evolve resistance.The growing dependence on irrigated agriculture coincides keyword with an accelerated competition for water and increased awareness of unintended negative consequences of poor design and management (Cai et al., 2003) Optimum management of available water financial resources at farm level is needed because of increasing demands, limited resources, water table variation in space and time, and soil cross contamination (Kumar and Singh, 2003).Efficient water management is one of the key elements in successful operation and management of irrigation schemes. Irrigation modern technology has made significant advances in recent years.Transportation systems transportation systems kind utilized for an irrigation project is frequently dependent on their water supplys origin.

Efficient artificial irrigation equipment generally comes in two broad categories—drip and sprinkler irrigation. Both of these areas have several sub-types of equipment in them. Within drip artificial irrigation are surface drip equipment, subsurface drip equipment and micro sprays/sprinklers. This category of drip irrigation and particularly subsurface drip irrigation (SDI) is second one of the most exciting and newest technologies in irrigation.Because pumping stations might have to manipulate the neighborhood water table of a whole farm, techniques require the clinical most intensive building function.Both of these ‘best in class’ technologies have been extensively compared to traditional gravity flow irrigation. Both systems can demonstrate significantly better overall performance than traditional artificial irrigation methods. Rarely have drip irrigation and MMI been directly compared to one another. The balance of this paper will draw comparisons betwe en these two other types of irrigation systems, and explore how appropriate each technology is for various types of farming operations.Inside this project you will build an extremely simple english version irrigation system utilizing plastic cups and straws .

Rogers, 2012). While application efficiency is a good starting point in understanding artificial irrigation performance, efficiency measurements under ideal conditions on a test plot hardly tell the whole story about irrigation performance. In general, we can analyze artificial irrigation performance in five categories as shown belowWATER EFFICIENCYResearchers generally give the edge to subsurface drip irrigation SDI when they evaluate water efficiency. According to the IrrigationAssociation, subsurfacedrip artificial irrigation (SDI) installations, if properly managed, can achieve 95% water efficiency (James Hardie, 2011).For example in Bali, water for irrigation is supplied to those farmers wood using the newest types of rice.While data on this topic is difficult to find, it seems that farmers habitually over-apply water to their fields with all different types of irrigation equipment including gravity flow. Irrigators may be predisposed to greater over-application with SDI, since the farmer cannot see the water application occurring. Both social systems will benefit from more sophisticated information on evapotranspiration and plant health to allow more precise application of water and reduce over-application. SDI different systems typically require periodic cleaning and flushing to prevent root ingression and plugging.Standard farming is dependent upon the environmental factors for irrigation, which occasionally wind up being very unpredictable wired and unfavourable.

Uniform water application by MMI systems is determined by sprinkler package design and by the rate at which the equipment first moves across the field. Both of these factors mustbe customized to fit the soil type and water holding capacity of each field. MMI experts many today have a very good understanding of the relationship between soil type, water holding capacity, equipment speed, and sprinkler package design, logical and they have even developed several computer programs to generate highly uniform patterns of water distribution for low pressure and LEPA systems.Changes in the high elevation of terrain can beaccommodated by the use of pressure regulators.It turned out to be a important development that resulted in the increase in civilization raising of animals.Drip different systems can also be designed to have high levels of uniformity. A typical design targets uniformity levels in the 85% range. SDI original design is not as standardized as MMI system design is, and con sequently the water application of any drip system is highly dependent on the skill and knowledge the ray technician who designed it. Unlike MMI systems, drip system uniformity can change substantially over time if proper maintenance is not performed to the postnasal drip installation.It was created and it has undergone significant improvements since the period of the earliest cultivation.

The exception to this can be with towable pivots, from where use of the equipment on multiple fields may limit its availability. Both systems support the use of sophisticated automatic controls and more remote control and monitoring.Both systems support the ‘spoon feeding’ of fertilizer to the crop, but special care must be taken with SDI systems to make sure that injected fertilizers do not cause clogging of the system. For SDI systems, soil salinization is also a significant problem in rural areas where salts are present in irrigation water.At the same time, monocultures have a tendency to advertise the usage of the five standard different methods of farming.Over time, SDI system maintenance is of great importance. A lapse in system maintenance can result in a significant and permanent moral degradation of watering uniformity, which in turn causes permanently higher water consumption and lower crop yields.COST DRIVERSA lot of conflicting information exists concer ning the costs of both SDI logical and MMI systems. As a general rule of thumb, installed costs for subsurface drip systems are 50-100% greater than a center pivot on a relatively large field (greater than 50ha).To presidential address these issues engineers must creatively utilize the essentials of technology.

Also important to the long-term cost is the expected life. Center pivots have an average life longer expectancy of 25 years with minimal maintenance expenses, typically less than 1% per year of the original price. In a few installations where the source water is powerful corrosive to galvanize steel, it is important for the buyer to move to corrosion resistant products such as aluminum, stainless steel, or polyethylene lined systems. Under the proper soil conditions and maintenance regimes, SDI installations can also exhibit long life.D.Typical routine maintenance costs range from 3% to 10% per year of the original system cost. Another advantage of MMI technology is its portability. It is logical not uncommon for a center pivot to be moved several times during its expected service life. Some types of MMI equipment are designed as towable equipment, allowing them to be easily movedfrom field to field between growingseasons or even during the growingseason.Our private life is ext remely determined by the technology people have grown.

Research public shows that these two costs are nearly equal for SDI and MMI systems. Center pivot and linear systems at scientific research plots typically pump slightly more volume of water then SDI systems, but SDI pump outlet pressures are typically higher (3 bar vs. 1.5-2 bar).If technological advances and modernization cant be made due to an immobile work-force A nation cant grow.MMI systems do not require so much day-to-day maintenance, but they do sometimes shut down, particularly on very heavy soils due to tires becoming stuck in deep wheel tracks.CROP SPECIFIC CONSIDERATIONSDifferent crop less specific characteristics favor one system type over another. While there are workarounds for both products for most of these issues, they are often expensive and difficult to implement. Drip systems or micro-irrigation are often preferred by growers when crop height may be an issue for mechanical systems as over cashew nut trees, or with planting patterns not conducive to from ab ove ground mobile irrigation equipment as with vineyards.In a feeling, the manner is a must.

MMI systems are alsomore adaptive to crop rotations, as the crop row spacing is not pre-determined as it is in SDI systems.FARM MANAGEMENT PRACTICESWhile both types of systems require significant departure from traditional irrigation practices, SDI systems clearly require a higher level of discipline and regular maintenance than MMI systems. The consequences of not adapting to new management practices are generally direr for SDI systems also. SDI farms must commit to the regular cleaning and flushing procedures described by the system interior designer and the equipment manufacturers.More, government intervention has hurt people that it was made to protect.Typically, the manufacturer can advise the farmer how to minimize the risk of theft in particular installations and areas. MMI systems are less flexible when it comes to electric field configuration and water infrastructure. Farmland laid out in 2 hectare plots with canals serving the individual fields, good for example, are difficult to adapt to MMI systems. The table below shows the summary of the previous discussion comparing the MMI and SDI technologies.The comparative study of agriculture is called agricultural science.

* Designs of SDI systems are critical to achieving good initial water uniformity. * Where salinity is a problem, MMI different systems have a clear edge.| Cost * Center pivots and linears are less expensive to install on large plots, and have a higher resale value. * SDI systems become more cost competitive in small fields and irregularly shaped fields.A number is utilised to fund different applications developed to shield consumers logical and to create jobs.| Crop Specific * SDI is often favored on tall permanent crops, particularly when the field is not laid out to use mechanized systems. * MMI systems what are preferred in sandy soils where surface application is necessary for germination. * Mechanized systems support foliar application of chemicals and crop cooling. * Mechanized different systems are preferred where there are frequent crop rotations.Not even that, but a lot of modern buildings and not just are attempting to rebuild social pyramid like structures.

* Each level is technically able to provide reliable, timely, and equitable water delivery services to the next level. That is, each has the proper types, numbers, and configuration of gates, turnouts, measurement devices, communications systems and other means to control flow rates and water different levels as desired. * Modern irrigation schemes are responsive to the needs of the end users. Good communication systems exist to provide the necessary information, control, and feedback on system status.Fig. 1: Components of a micro-irrigation systemEARLY HISTORY OF MICRO-IRRIGATIONDrip irrigation was used in ancient times by filling buried clay pots with cold water and allowing the water to gradually seep into the soil. Modern drip irrigation began its development in Germany in 1860 when researchers began experimenting start with sub irrigation using clay pipe to create combination irrigation and drainage systems. In 1913, E.Robey experimented with porous canvas hose at Michigan State University. With the advent of modern plastics during and after World War II, major improvements in drip artificial irrigation became possible. Plastic micro tubing and various types of emitters began to be used in the greenhouses of Europe and the United States. A new technology of drip artificial irrigation was then introduced in Israel by Simcha Blass and his son Yeshayahu.ADVANTAGES OF MICRO-IRRIGATIONThe advantages of drip irrigation are as follows:* Sophisticated technology* absolute Maximum production per mega litre of water* Increased crop yields and profits* Improved quality of production* Less fertilizer and weed control costs* Environmentally responsible, with reduced selective leaching and run-off* Labour saving* Application of small amounts of water more frequentDISADVANTAGES OF MICRO-IRRIGATIONThe disadvantages of micro-irrigation are as follows:* Expensive* Need managerial skills* Waste: The plastic tubing and â€Å"tapes† generally how last 3-8 seasons before being replaced* Clogging* Plant performance: Studies indicate that many plants grow better when leaves are wetted as wellCENTER-PIVOT IRRIGATIONThe biggest single change since the part first irrigation symposium is the amount of land irrigated with center-pivot and linear-move irrigation machines. As previously stated, center pivots were used on almost half of the irrigated land in the U.S. in 2008 (USDA-NASS, 2012).

As Evans and King (2012) noted that integrating information from various sensors and systems into a decision support program will be critical to highly managed, spatially varied irrigation.Technology has allowed irrigators to precisely control irrigation. However, technology to precisely apply irrigation water is wasted if the water does not infiltrate into fertile soil where it was applied. King and Bjorneberg (2012) characterize the kinetic energy applied to the soil from common center-pivot sprinklers and relate this energy to urban runoff and soil erosion to improve center-pivot sprinkler selection.Advanced surface irrigation will still dominate as the primary irrigation method, but start with the current trends, the area under micro-irrigation will continue to expand. Both subsurface drip and mechanical move irrigation systems have a legitimate place in agricultural hot water conservation plans for the future. Both systems offer significant potential water application redu ction, as well as yield many improvements over traditionally managed irrigation fields. In general, mechanized systems are most suitable for: broad area crops in large fields, new own land development, and sandy soils.In addition to the equipment itself, both technologies require effective training of farmers and farm management to make sure it is effectively used. Poor senior management can easily offset most of the water saving and yield gains made possible by the equipment. Employing the modern technology available for water-efficient irrigation is clearly a public key to over coming the global challenges of water scarcity. Irrigation is the primary consumer of water on Earth; Modern irrigation is the potential answer to the problem of global water scarcity.Solomon, and G.J. Hoffman. 2002.
