Human Behavior Essay
Human behavior can negatively or positively affect the environment. Environmental settings such as pollution, crowding, heat, or noise may be a source of that can negatively impact the environmental quality, conditions. The environment can be positively impacted by structures, green areas or health facilities. There are simple solutions that can help in getting started with these efforts. Explain how environmental cues shape behavior and provide at least one example Environmental cues are the normal elements that the general public does not control. For this reason, individuals are required to obey the rules with regard to the environmental cues. Examples would be the environmental cues such as sustenance accessibility and high temperature fluctuations commonly upset the nourishing routines of wildlife. A grocery store, as another example can has been sensibly designed to give the experience to take full advantage of the amount of money you will spend by the time you walk out. This i ncludes fundamentals like inserting necessities such as milk and eggs on the furthest side from the entry so you have to walk through additional lanes to get there, placing foods with kid appeal on lower shelves so they can see and request it, as well as placing impulse objects by the cash registers to get your attention while waiting in line. Even the smell drifting from the bakery has been intended to increase the amount of items in your shopping cart. The human mind typically takes part in certain actions centered on the familiar environmental cues and patterns. If people gather in an environment where the use of drugs is rampant, this means that majority of the population will take on to this behavior without bearing in mind the harmful effects that their acts could have in the long run. This means that human beings have a part of planting something in the environment that can generate change and reduce the negative effects that are currently experienced. A good model would beà implementation of a practice to make use of decomposable bags for grocery shopping as a replacement for the disposable plastics. This is because the plastics ordinarily have harmful effects on the environment in several ways. People typically do not dispose of the correctly and they have the potential of being a health risk to animals if they happen to swallow them while eating. The implementation of this method will influence the environment positively in the long run because the behaviors of people will change accordingly. Evaluate how behavior can be modified to support sustainability and how this can limit a negative impact on the environment Behavior can be modified for example in our daily activities. Most people wake up in the more and brush their teeth as well as shower. Both of these activities require using water. Instead of letting the water run constantly while engaging in these activities a person can turn the water off while brushing and only use as needed or when showering rinse with the water to get wet then turn off while lathering up and back onto rinse off. This will all lessen the time the water is being used for less waste. When grocery shopping a person can elect to use either paper or their own environmentally safe bags for shopping. Sometimes a person tends to utilize their car out of habit and convenience. Instead of driving to the corner store a person may elect to walk or ride a bicycle. This in turn will reduce the amount of pollutants released in the air, also affording exercise for the individual. Describe how social norms influence behavior and beliefs about the environment Social norms affect t he method in which people conduct themselves, depending on the communal experiences and what the society expects of them. With the current generation nonetheless, these social norms have been washed away in many communities and this has had a very negative impact on the environment as well as the society at large. For instance, smoking was strictly prohibited for students and other younger generations. This is currently not the case as campus students are leading in smoking. This on the other hand has impacted the environment in a negative manner. Smoking on campus is still a problem and imposes a health risk for students and negative environmental impacts. There is a need to protect students, faculty and staff from exposure to second hand smoke on college campuses and create anticipation that this living and working environment be smoke free.à The argument that a person who smokes in the campus exposes the other nonsmokers to second hand smoke, something which can have negative effects to both their health. There are policies that can be implemented in campus to lessening the rate of smoking and chan ge the current attitudes of students towards this act. This is actually proven from the findings that students who study in areas where smoking is prohibited do not smoke at all in their entire lives. Smoking on campus has become widespread in spite of the health and environmental effects that are connected with this act. This is something that is raising voices of many advocates and particularly because of the negative effects that are connected with it. The worst part is that the people who do not smoke are also affected from the discharged smoke. It is consequently significant to come up with guidelines that will help in removing this act. This is the only way in which the environment will be kept and the health effects connected with smoking with diminish considerably. Identify at least two possible solutions that could successfully change behavior and habits in order to lessen negative environmental impact There are several possible solutions to possibly change the behaviors and habits that negatively affect the environment. The option of utilizing public transportation in turns reduces the fact of at least one extra vehicle being on the road that will cause pollution. Once people get rid of the negative associations that come with using public transportation. Another method would be to use energy efficient appliances. An individual can start off by replacing all the light bulbs in the house with energy efficient ones. Also replacing appliances to conserve the environment over a period of time. There are many things that individuals can do on a daily basis to positively impact the environment. It may be easier to start out in small steps maybe within the individual household, then work towards others on the outside. Any step or effort made is a positive step in the right direction. Changing the behavior and effects on the environment takes the work of all individuals that share this Earth. One person can only make so much of a difference. References Festinger, L. (2009).

The Host Chapter 57: Completed
It was a small tribunal this time, not like the trial for Kyle's life. Ian brought only Jeb, Doc, and Jared. He knew without having to be told that Jamie must not be allowed anywhere near these proceedings. Melanie would have to give that goodbye for me. I couldn't face that, not with Jamie. I didn't care if it was cowardly of me. I wouldn't do it. Just one blue lamp, one dim circle of light on the stone floor. We sat on the edge of the ring of light; I was alone, the four men facing me. Jeb had even brought his gun-as if it were a gavel and would make this more official. The smell of sulfur brought back the painful days of my mourning; there were some memories that I would not regret losing when I was gone. ââ¬Å"How is she?â⬠I asked Doc urgently as they settled in, before they could get started. This tribunal was a waste of my small store of time. I was worried about more important things. ââ¬Å"Which one?â⬠he responded in a weary voice. I stared at him for a few seconds, and then my eyes grew wide. ââ¬Å"Sunny's gone? Already?â⬠ââ¬Å"Kyle thought it was cruel to make her suffer longer. She wasâ⬠¦ unhappy.â⬠ââ¬Å"I wish I could have said goodbye,â⬠I murmured to myself. ââ¬Å"And good luck. How is Jodi?â⬠ââ¬Å"No response yet.â⬠ââ¬Å"The Healer's body?â⬠ââ¬Å"Trudy took her away. I think they went to get her something to eat. They're working on finding a temporary name she likes, so we can call her something besides the body.â⬠He smiled wryly. ââ¬Å"She'll be fine. I'm sure she will,â⬠I said, trying to believe the words. ââ¬Å"And Jodi, too. It will all work out.â⬠No one called me on my lies. They knew I was saying this for myself. Doc sighed. ââ¬Å"I don't want to be away from Jodi long. She might need something.â⬠ââ¬Å"Right,â⬠I agreed. ââ¬Å"Let's get this over with.â⬠The quicker the better. Because it didn't matter what was said here; Doc had agreed to my terms. And yet there was some stupid part of me that hopedâ⬠¦ hoped that there was a solution that would make everything perfect and let me stay with Ian and Mel with Jared in a way that absolutely no one would suffer for. Best to crush that impossible hope quickly. ââ¬Å"Okay,â⬠Jeb said. ââ¬Å"Wanda, what's your side?â⬠ââ¬Å"I'm giving Melanie back.â⬠Firm, short-no reasons to argue against. ââ¬Å"Ian, what's yours?â⬠ââ¬Å"We need Wanda here.â⬠Firm, short-he was copying me. Jeb nodded to himself. ââ¬Å"That's a tricky one. Wanda, why should I agree with you?â⬠ââ¬Å"If it were you, you'd want your body back. You can't deny Melanie that.â⬠ââ¬Å"Ian?â⬠Jeb asked. ââ¬Å"We have to look at the greater good, Jeb. Wanda's already brought us more health and security than we've ever had. She's vital to the survival of our community-of the entire human race. One person can't stand in the way of that.â⬠He's right. Nobody asked you. Jared spoke up. ââ¬Å"Wanda, what does Mel say?â⬠Ha, Mel said. I stared into Jared's eyes, and the strangest thing happened. All the melting and melding I had just been through was shoved aside, into the smallest part of my body, the little corner that I took up physically. The rest of me yearned toward Jared with the same desperate, half-crazed hunger I'd felt since the first time I'd seen him here. This body barely belonged to me or to Melanie-it belonged to him. There really wasn't room enough for the two of us in here. ââ¬Å"Melanie wants her body back. She wants her life back.â⬠Liar. Tell them the truth. No. ââ¬Å"Liar,â⬠Ian said. ââ¬Å"I can see you arguing with her. I'll bet she agrees with me. She's a good person. She knows how much we need you.â⬠ââ¬Å"Mel knows everything I know. She'll be able to help you. And the Healer's host. She knows more than I ever did. You'll be fine. You were fine before I was here. You'll survive, just like before.â⬠Jeb blew out a puff of air, frowning. ââ¬Å"I don't know, Wanda. Ian's got a point.â⬠I glared at the old man and saw that Jared was doing the same. I looked away from that standoff to level a grim glance at Doc. Doc met my eyes, and his face clenched with pain. He understood the reminder I was giving him. He'd promised. This tribunal didn't overrule that. Ian was watching Jared-he didn't see our silent exchange. ââ¬Å"Jeb,â⬠Jared protested. ââ¬Å"There's only one decision here. You know that.â⬠ââ¬Å"Is there, kid? Seems to me there's a whole barrel of 'em.â⬠ââ¬Å"That's Melanie's body!â⬠ââ¬Å"And Wanda's, too.â⬠Jared choked on his response and had to start over. ââ¬Å"You can't leave Mel trapped in there-it's like murder, Jeb.â⬠Ian leaned forward into the light, his face suddenly furious again. ââ¬Å"And what is it that you're doing to Wanda, Jared? And the rest of us, if you take her away?â⬠ââ¬Å"You don't care about the rest of anybody! You just want to keep Wanda at Melanie's expense-nothing else matters to you.â⬠ââ¬Å"And you want to have Melanie at Wanda's expense-nothing else matters to you! So, with those things being equal, it comes down to what's best for everyone else.â⬠ââ¬Å"No! It comes down to what Melanie wants! That's her body!â⬠They were both crouched halfway between sitting and standing now, their fists clenched and their faces twisted with rage. ââ¬Å"Cool it, boys! Cool it right now,â⬠Jeb ordered. ââ¬Å"This is a tribunal, and we're going to stay calm and keep our heads. We've got to think about every side.â⬠ââ¬Å"Jeb -â⬠Jared began. ââ¬Å"Shut up.â⬠Jeb chewed on his lip for a while. ââ¬Å"Okay, here's how I see it. Wanda's right -ââ¬Å" Ian lurched to his feet. ââ¬Å"Hold it! Sit yourself back down. Let me finish.â⬠Jeb waited until Ian, the tendons standing out in his taut neck, stiffly returned to a seated position. ââ¬Å"Wanda is right,â⬠Jeb said. ââ¬Å"Mel needs her body back. But,â⬠he added quickly when Ian tensed again, ââ¬Å"but I don't agree with the rest, Wanda. I think we need you pretty bad, kid. We got Seekers out there lookin' for us, and you can talk right to 'em. The rest of us can't do that. You save lives. I got to think about the welfare of my household.â⬠Jared spoke through his teeth. ââ¬Å"So we get her another body. Obviously.â⬠Doc's crumpled face lifted. Jeb's white caterpillar eyebrows touched his hairline. Ian's eyes widened and his lips pursed. He stared at me, consideringâ⬠¦ ââ¬Å"No! No!â⬠I shook my head frantically. ââ¬Å"Why not, Wanda?â⬠Jeb asked. ââ¬Å"Don't sound like a half-bad idea to me.â⬠I swallowed and took a deep breath so my voice wouldn't turn hysterical. ââ¬Å"Jeb. Listen to me carefully, Jeb. I am tired of being a parasite. Can you understand that? Do you think I want to go into another body and have this start all over again? Do I have to feel guilty forever for taking someone's life away from them? Do I have to have someone else hate me? I'm barely a soul anymore-I love you brutish humans too much. It's wrong for me to be here, and I hate feeling that.â⬠I took another breath and spoke through the tears that were falling now. ââ¬Å"And what if things change? What if you put me in some-one else, steal another life, and it goes wrong? What if that body pulls me after some other love, back to the souls? What if you can't trust me anymore? What if I betray you next time? I don't want to hurt you!â⬠The first part was the pure and unadorned truth, but I was lying wildly through the second. I hoped they wouldn't hear that. It would help that the words were barely coherent, my tears turned to sobs. I would never hurt them. What had happened to me here was permanent, a part of the very atoms that made up my small body. But maybe, if I gave them a reason to fear me, they would more easily accept what had to be. And my lies worked, for once. I caught the worried glance Jared and Jeb exchanged. They hadn't thought of that-of my becoming untrustworthy, becoming a danger. Ian was already moving to put his arms around me. He dried my tears against his chest. ââ¬Å"It's okay, honey. You don't have to be anyone else. Nothing's going to change.â⬠ââ¬Å"Hold on, Wanda,â⬠Jeb said, his shrewd eyes suddenly sharper. ââ¬Å"How does going to one of those other planets help you? You'll still be a parasite, kid.â⬠Ian flinched around me at the harsh word. And I flinched also, because Jeb was too insightful, as always. They waited for my answer, all but Doc, who knew what the real answer was. The one I wouldn't give. I tried to say only true things. ââ¬Å"It's different on other planets, Jeb. There isn't any resistance. And the hosts themselves are different. They aren't as individualized as humans, their emotions are so much milder. It doesn't feel like stealing a life. Not like it feels here. No one will hate me. And I'd be too far away to hurt you. You'd be saferâ⬠¦Ã¢â¬ The last part sounded too much like the lie it was, so I let my voice trail off. Jeb stared at me through narrowed eyes, and I looked away. I tried not to look at Doc, but I couldn't help one brief glance, to make sure he understood. His eyes locked on mine, clearly miserable, and I knew that he did. As I quickly lowered my gaze, I caught Jared staring at Doc. Had he seen the silent communication? Jeb sighed. ââ¬Å"This isâ⬠¦ a pickle.â⬠His face turned into a grimace as he concentrated on the dilemma. ââ¬Å"Jeb -â⬠Ian and Jared said together. They both stopped and scowled at each other. This was all just a waste of time, and I had only hours. Just a few more hours, I knew that for certain now. ââ¬Å"Jeb,â⬠I said softly, my voice barely audible over the spring's gushing murmur, and everyone turned to me. ââ¬Å"You don't have to decide right now. Doc needs to check on Jodi, and I'd like to see her, too. Plus, I haven't eaten all day. Why don't you sleep on it? We can talk again tomorrow. We've got plenty of time to think about this.â⬠Lies. Could they tell? ââ¬Å"That's a good idea, Wanda. I think everyone here could use a breather. Go get some food, and we'll all sleep on it.â⬠I was very careful not to look at Doc now, even when I spoke to him. ââ¬Å"I'll be along to help with Jodi after I eat, Doc. See you later.â⬠ââ¬Å"Okay,â⬠Doc said warily. Why couldn't he keep his tone casual? He was a human-he should have been a good liar. ââ¬Å"Hungry?â⬠Ian murmured, and I nodded. I let him help me up. He latched on to my hand, and I knew he would be keeping a tight hold on me now. That didn't worry me. He slept deeply, like Jamie. As we walked from the dark room, I could feel eyes on my back, but I wasn't sure whose. Just a few more things to do. Three, to be precise. Three last deeds to be completed. First, I ate. It wouldn't be nice to leave Mel with her body uncomfortable from hunger. Besides, the food was better since I'd been raiding. Something to look forward to rather than endure. I made Ian get the food and bring it to me while I hid in the field where half-grown sprouts of wheat replaced the corn. I told Ian the truth so that he would help me: I was avoiding Jamie. I didn't want Jamie frightened by this decision. It would be harder for him than for Jared or Ian-they each took one side. Jamie loved us both; he would be more evenly torn. Ian did not argue with me. We ate in silence, his arm tight around my waist. Second, I went to see Sunny and Jodi. I expected to see three glowing cryotanks on top of Doc's desk, and I was surprised that there were still just the two Healers, set in the center. Doc and Kyle hovered over the cot where Jodi lay inert. I walked quickly to them, about to demand to know where Sunny was, but when I got closer, I saw that Kyle had an occupied cryotank cradled in one arm. ââ¬Å"You'll want to be gentle with that,â⬠I murmured. Doc was touching Jodi's wrist, counting to himself. His lips pressed into a thin line when he heard my voice, and he had to begin over again. ââ¬Å"Yeah, Doc told me that,â⬠Kyle said, his gaze never leaving Jodi's face. A dark, matched set of bruises was forming under his eyes. Was his nose broken again? ââ¬Å"I'm being careful. I justâ⬠¦ didn't want to leave her alone over there. She was so sad and soâ⬠¦ sweet.â⬠ââ¬Å"I'm sure she'd appreciate it, if she knew.â⬠He nodded, still staring at Jodi. ââ¬Å"Is there something I'm supposed to be doing here? Is there some way to help?â⬠ââ¬Å"Talk to her, say her name, talk about things she'll remember. Talk about Sunny, even. That helped with the Healer's host.â⬠ââ¬Å"Mandy,â⬠Doc corrected. ââ¬Å"She says it's not exactly right, but it's close.â⬠ââ¬Å"Mandy,â⬠I repeated. Not that I would need to remember. ââ¬Å"Where is she?â⬠ââ¬Å"With Trudy-that was a good call there. Trudy's exactly the right person. I think she's gotten her to sleep.â⬠ââ¬Å"That's good. Mandy will be okay.â⬠ââ¬Å"I hope so.â⬠Doc smiled, but it didn't affect his gloomy expression much. ââ¬Å"I've got lots of questions for her.â⬠I looked at the small woman-it was still impossible to believe that she was older than the body I wore. Her face was slack and vacant. It frightened me a little-she'd been so vibrantly alive when Sunny was inside. Would Melâ⬠¦? I'm still here. I know. You'll be fine. Like Lacey. She winced, and so did I. Never like Lacey. I touched Jodi's arm softly. She was much like Lacey in some ways. Olive skinned and black haired and tiny. They could almost be sisters, except that Jodi's sweet, wan face could never look so repellent. Kyle was tongue-tied, holding her hand. ââ¬Å"Like this, Kyle,â⬠I said. I brushed her arm again. ââ¬Å"Jodi? Jodi, can you hear me? Kyle's waiting for you, Jodi. He got himself in a lot of trouble getting you here-everybody who knows him wants to beat him senseless.â⬠I grinned wryly at the big man, and his lips curled up at the corners, though he didn't look up to see my smile. ââ¬Å"Not that you're surprised to hear that,â⬠Ian said beside me. ââ¬Å"When hasn't that been the case, eh, Jodi? It's good to see you again, sweetheart. Though I wonder if you feel the same way. Must have been a nice break to get rid of this idiot for so long.â⬠Kyle hadn't noticed his brother was there, attached like a vise to my hand, until Ian spoke. ââ¬Å"You remember Ian, of course. Never has managed to catch up to me in anything, but he keeps trying. Hey, Ian,â⬠Kyle added, never moving his eyes, ââ¬Å"you got anything you want to say to me?â⬠ââ¬Å"Not really.â⬠ââ¬Å"I'm waiting for an apology.â⬠ââ¬Å"Keep waiting.â⬠ââ¬Å"Can you believe he kicked me in the face, Jodes? For no reason at all.â⬠ââ¬Å"Who needs an excuse, eh, Jodi?â⬠It was oddly pleasant, the banter between the brothers. Jodi's presence kept it light and teasing. Gentle and funny. I would have woken up for this. If I were her, I would have been smiling already. ââ¬Å"Keep it up, Kyle,â⬠I murmured. ââ¬Å"That's just right. She'll come around.â⬠I wished I would get to meet her, to see what she was like. I could only picture Sunny's expressions. What would it be like for everyone here, meeting Melanie for the first time? Would it seem the same to them, as if there were no difference? Would they really grasp that I was gone, or would Melanie simply fill the role I had? Maybe they would find her entirely different. Maybe they would have to adjust to her all over again. Maybe she would fit in the way I never had. I pictured her, which was picturing me, the center of a crowd of friendly faces. Pictured us with Freedom in our arms and all the humans who had never trusted me smiling with welcome. Why did that bring tears to my eyes? Was I really so petty? No, Mel assured me. And they'll miss you-of course they will. All the best people here will feel your loss. She seemed to finally accept my decision. Not accept, she disagreed. I just can't see any way to stop you. And I can feel how close it is. I'm scared, too. Isn't that funny? I'm absolutely terrified. That makes two of us. ââ¬Å"Wanda?â⬠Kyle said. ââ¬Å"Yes?â⬠ââ¬Å"I'm sorry.â⬠ââ¬Å"Umâ⬠¦ why?â⬠ââ¬Å"For trying to kill you,â⬠he said casually. ââ¬Å"Guess I was wrong.â⬠Ian gasped. ââ¬Å"Please tell me you have some kind of recording device available, Doc.â⬠ââ¬Å"Nope. Sorry, Ian.â⬠Ian shook his head. ââ¬Å"This moment should be preserved. I never thought I'd live to see the day that Kyle O'Shea would admit to being wrong. C'mon, Jodi. That ought to shock you awake.â⬠ââ¬Å"Jodi, baby, don't you want to defend me? Tell Ian I never have been wrong before.â⬠He chuckled. That was nice. It was nice to know that I'd earned Kyle's acceptance before I left. I hadn't expected that much. There was no more I could do here. There was no point in lingering. Jodi would either come back or she would not, but neither outcome would change my path now. So I proceeded to my third and final deed: I lied. I stepped away from the cot, took a deep breath, and stretched my arms. ââ¬Å"I'm tired, Ian,â⬠I said. Was it really a lie? It didn't sound so false. It had been a long, long day, this, my last day. I'd been up all night, I realized. I hadn't slept since that last raid; I must have been exhausted. Ian nodded. ââ¬Å"I'll bet you are. Did you stay up with the Heal-with Mandy all night?â⬠ââ¬Å"Yeah.â⬠I yawned. ââ¬Å"Have a nice night, Doc,â⬠Ian said, pulling me toward the exit. ââ¬Å"Good luck, Kyle. We'll be back in the morning.â⬠ââ¬Å"Night, Kyle,â⬠I murmured. ââ¬Å"See you, Doc.â⬠Doc glowered at me, but Ian's back was to him, and Kyle was staring at Jodi. I returned Doc's glare with a steady gaze. Ian walked with me through the black tunnel, saying nothing. I was glad he wasn't in the mood for conversation. I wouldn't have been able to concentrate on it. My stomach was twisting and turning, wringing itself into strange contortions. I was done, all my tasks accomplished. I only had to wait a bit now and not fall asleep. Tired as I was, I didn't think that would be a problem. My heart was pounding like a fist hitting my ribs from the inside. No more stalling. It had to be tonight, and Mel knew that, too. What had happened today with Ian had shown me that. The longer I stayed, the more tears and arguments and fights I would cause. The better the chance that I or someone else would slip up and Jamie would find out the truth. Let Mel explain it after the fact. It would be better that way. Thanks so much, Mel thought; her words flowed fast, in a burst, her fear marring her sarcasm. Sorry. You don't mind too much? She sighed. How can I mind? I'd do anything you asked me to, Wanda. Take care of them for me. I would have done that anyway. Ian, too. If he'll let me. I've got a feeling he might not like me so much. Even if he won't let you. I'll do whatever I can for him, Wanda. I promise. Ian paused in the hall outside the red and gray doors to his room. He raised his eyebrows, and I nodded. Let him think I was still hiding from Jamie. That was true, too. Ian slid the red door aside, and I went straight to the mattress on the right. I balled up there, knotting my shaking hands in front of my hammering heart, trying to hide them behind my knees. Ian curled around me, holding me close to his chest. This would have been fine-I knew that he would end up sprawled out in all directions when he was really asleep-except that he could feel my trembling. ââ¬Å"It's going to be fine, Wanda. I know we'll find a solution.â⬠ââ¬Å"I truly love you, Ian.â⬠It was the only way I could tell him goodbye. The only way he would accept. I knew he would remember later and understand. ââ¬Å"With my whole soul, I love you.â⬠ââ¬Å"I truly love you, too, my Wanderer.â⬠He nuzzled his face against mine until he found my lips, then he kissed me, slow and gentle, the flow of molten rock swelling languidly in the dark at the center of the earth, until my shaking slowed. ââ¬Å"Sleep, Wanda. Save it for tomorrow. It will keep for the night.â⬠I nodded, moving my face against his, and sighed. Ian was tired, too. I didn't have to wait long. I stared at the ceiling-the stars had moved above the cracks here. I could see three of them now, where before there had been only two. I watched them wink and pulse across the blackness of space. They did not call to me. I had no desire to join them. One at a time, Ian's arms fell away from me. He flopped onto his back, muttering in his sleep. I didn't dare wait any longer; I wanted too badly to stay, to fall asleep with him and steal one more day. I moved cautiously, but he was in no danger of waking. His breathing was heavy and even. He wouldn't open his eyes till morning. I brushed his smooth forehead with my lips, then rose and slid out the door. It was not late, and the caves were not empty. I could hear voices bouncing around, strange echoes that might have been coming from anywhere. I didn't see anyone until I was in the big cave. Geoffrey, Heath, and Lily were on their way back from the kitchen. I kept my eyes down, though I was very glad to see Lily. In the brief glimpse I allowed myself, I could see that she was at least standing upright, her shoulders straight. Lily was tough. Like Mel. She'd make it, too. I hurried to the southern corridor, relieved when I was safe in the blackness there. Relieved and horrified. It was really over now. I'm so afraid, I whimpered. Before Mel could respond, a heavy hand dropped on my shoulder from the darkness. ââ¬Å"Going somewhere?ââ¬

Earthquakes on the Chamman and Chiltan Fault Lines in Quetta Pakistan Research Paper
Earthquakes on the Chamman and Chiltan Fault Lines in Quetta Pakistan Specifically in 1935 - Research Paper Example Although there are still several catalogs of earthquakes that exist, the early events were in particular due to some errors, location biasness and incompleteness. Using original sources, it has been confirmed that more than a thousand earthquakes were macro-seismic locations and have assigned the MS magnitudes to the earthquakes since 1892. There have been 34 important earthquakes recorded in this reason of which one of the most significant one took place on 31st May 1935 (Erduranââ¬Å½ et al., 2012). This earthquake took place at 3am in the middle of the night. It was known as the deadliest earthquake in South Asia. This was the most seismic region of Pakistan at the top of the Chamman and Chiltan fault lines. The earthquake lasted for three minutes but had several immense aftershocks. The tremors of the earthquake were felt a long distance away and the destruction was caused in all the towns near Quetta, the main city, including the city itself. The earthquake had killed 30,000 to 60,000 people in the region. The aftershocks, however, did not cause much damage in Quetta but in the surrounding regions. The scientists have found out the main causes of the earthquakes in Baluchistan from 1892 to 2001 and have analyzed the issues as a wide topic. Most of the research was based on the 1935 earthquake as it is marked as a few of the deadliest ones in the 20th century. The significance of this topic in the lives of the Pakistanis and Asians can be seen through various consequences and analyses made by the scientists. To develop the topic and introduce the issues, it is important to see what type of an earthquake it was actually. The earthquake was, as recorded in the new instruments, 7.7 MW while the previous instruments had recorded 8.1 MW which was a wrongly calculated amount. The epicenter of the earthquake was recorded to be 4.0 km from Ali Jaan, a town in Quetta. The focal depth of the earthquake was 17kms ?(Ambraseys & Bilham, 2003). ? According to the scientists these earthquakes took place in Baluchistan because of the fault lines in the region. It happened due to the two blocks of earth suddenly colliding past one another. The earthquake of 1935 is recorded to have no foreshocks which are the movements felt before the earthquake happened. Records show that there were no such claims. However, it is true that scientists cannot tell whether it is a foreshock before the main earthquake happens, but after the earthquake occurred in 1935, it was held that there were no foreshocks experienced. Even though there were no foreshocks, the earthquake had some unusual events recorded prior to the earthquake. It is true that scientists have not yet found a way in which the earthquakes can be predicted, yet they can analyze how and when they are most likely to occur in future. Quetta is said to be hit by the 1935 quake again in the near future however, the time can never be accurately told. The unusual events that scientists recorded before the earthquake were unusual bright lights, flashes of lights in the mountains, landslides, dust clouds and rock falls. Unusual event s seem to be unjustified even after many years of research as the scientists say that earthquakes have very less to do with the weather changes. They cannot be predicted by any machines or instruments. They shake the earthââ¬â¢s surface because of the collision of faults. The Quetta earthquake was also a sudden event where hundreds of people were buried under the rubble because it was 3am in the morning and most of them were not awake to assess the emergency. The significance and further details of the earthquake are discussed later. However, this earthquake holds immense significance as it

Effect on British Business for Joining Euro Zone Essay
Effect on British Business for Joining Euro Zone - Essay Example Labour Productivity: The output per worker is the ratio of total output and total employment and the unit labour cost is total labour costs-to-output. The output per worker has remained unchanged in the last two quarters but unit labour costs have increased by 0.3% in the last two quarters (ONS, 2011, p.8). Labour Disputes: These are associated with the strikes with respect to the terms and conditions related to employment. During the last 12 months before October 2011, there were 417,000 lost working days from 135 strikes (ONS, 2011, p.9). Unemployment: This measures the unemployed people who are actively seeking work and ready to join work immediately. The unemployment rate was up 40 basis points from previous year leading to 8.3% unemployment rate. The unemployed youth formed 22% of economically active population. As per the international guidelines, people in full-time education are unemployed if they are looking for jobs since last four weeks (ONS, 2011, p.11). It can be seen th at the public sector cutting of jobs has worsened the employment situation in Britain. The Conservative Party seeks to bring down the deficit to maintain the record low interest rates and avoid situations faced by Greece, Spain and Portugal (Politics.co.uk, 2011). Some people view the reasons for unemployment especially youth unemployment is because of too much reliance on unemployment benefits provided by the government and unwillingness to accept the jobs offered whereas the corporate sector believes the burden of red tape, taxes and minimum wages have tied up their businesses and prevented them from hiring more people (Palmer, 2011). Measures for Reducing the Unemployment There are three types of... Based on this research, the British economy has been affected at first due to joining the Euro Zone as the government has to cop up with the new policies of the regulatory body which make the laws for the Euro Zone. The British government has to incur certain costs for adopting with the new policies, for educate the people so that they can cop up with the new currency and new policies. Though the government had to face some initial costs but the economy are benefited from a long term view. The businessman of UK would get the new opportunity for enhance their business in the other Euro Zone countries. As the currency of 17 countries is same the transaction cost of the business has got lower. The interest rates of the countryââ¬â¢s central banks getting lower, the mortgage also get down. Along with this the credibility of the Euro currency is improving as the same currency is used by 17 countries. The currency is not fluctuating as the previous so the investor doesnââ¬â¢t have to hedge their investment. The opportunity for the business owners is that they have access for a larger base of customers as well as they can utilize the larger workforce available to them. The British small and medium companies will have the opportunity to get the foreign funds as the transaction costs are not as high in the Euro Zone as there is the same currency operating in every country. The UK business owners can also have the ideas and the technologies which can enhance the revenue and subsequently profit of the company and thus the gross domestic product of the country can be improved.

The Effects of Antidepressant Treatment in Prenatally Stressed Rats Literature review
The Effects of Antidepressant Treatment in Prenatally Stressed Rats - Literature review Example Prior studies suggest that abnormalities in the transmission of hippocampal glutamate play a vital role in the pathophysiology of mood and anxiety ailments. Apparently, many of the studies borrowed greatly from prior studies on the same line, but other studies present actual studies to provide empirical evidence on the same (Marrocco et al., 2014). Alternatively, there is empirical evidence in regards to a model of depression and anxiety, which is central to the hypo-function hippocampus, and many of the studies utilize female rats because of their high incidence of major depression in women (Van et al., 2011). Exposure to chronic stress in adulthood leads to the improvement of production of glutamate in the hippocampus. In this regard, there are other treatments for anxiety noted from the cited articles. The evidence asserts that a portion of the hippocampus, which specifically encodes memories of stress, emotions, and anxiety, is in line with the postulated hypothesis of stress-rel ated disorders (Marrocco et al., 2014). In addition, chronic stress can result in long-term physiological and behavioral disorders such as low birth weight, infant morbidity, anxiety, and lack of sleep and cognition retardation (Maccari et al., 2003). Other scholars have aimed to establish a link between PRS exposure, and alcohol consumption (Richardson et al., 2008). In this perspective, there is a variance between male and female consumption of alcohol, and research suggests that males show reduced activation of acute alcohol administration (Richardson et al., 2008). Recently, evidence has come up showing that PRS has can prevent the reduction in the consumption of alcohol-induced by chronic stress in adult alcohol-preferring female rats (Darnaudery et al., 2007). Many of the scholars have utilized rats, as subjects, in their studies, to show how mood disorders can be stable throughout the life of a human being (Vallee et al., 1999). This is because it is possible to notice the ai lments early and later as they develop (Henry et al., 994).The methods utilized by many of the studies follow an evidence-based approach, whereby the aim was to test the evidence (Darnaudery et. al., 2007). In scientific research, the objective is to achieve empirical evidence and because most of the studies identified followed experimental approaches (Nestle and Hyman, 2010). This approach is effective, and it utilizes randomized trials, including a control group and experimental group. The two groups help investigators to compare results, or findings appropriately (Richardson et al., 2008). In other cases, the investigators further, classify the control and experimental groups in terms of sex, age to find out the variations in the provided context. The most important advantage of this approach is to increase internal validity (Henry et al., 994). This means that in the event of subsequent studies on the same subject will amount to similar findings (Morley-Fletcher et al., 2003). C hronic treatment of the PRS rats using antidepressants had a positive outcome, in that it resulted in normal levels of synaptic vesicle-associated proteins in rats (Maccari et al., 2003). In this context, the use of anxiolytics and tranquilizers escalate the rigidity in the animal models of depression (Moley-Fletcher et al., 2003). Alternatively, depolarization-evoked the production of glutamate was in high PRS rats.

Assignment Example fixed and the damping is reduced to zero, the wave oscillates with gradually increasing amplitude above the natural frequency of the generating medium. When set on the loose end, with the initial default conditions kept constant, the wave gradually decays in an exponential manner and when the damping is offset the wave oscillates with almost equal amplitude. However setting no end on, with zero damping a wave with crests of equal amplitude is generated and a smooth wave flow is observed. Additionally, when the damping is set at zero and at loose end, the amplitude of the wave increases gradually and the wave interferes destructively and starts over and over again. A similar condition is experienced when it is set at the fixed end with zero amplitude, in which case, the reflected part of the wave interferes destructively constantly. The natural phenomena like tides in oceans, earthquakes and waves on a string are examples The term standing wave is used to denote the resonant mode of the vibrating string or the simulation used in this experiment. The resonance in this simulation is created by constructive interference of two waves which travel in opposite directions in the same medium creating a simple harmonic oscillator. Diagrams 1 through 4 in the inserted pictures above show how the wave transits from one stage to another and eventually returns to the initial position showing a simple harmonic

Early and late industrialization Essay Example | Topics and Well Written Essays - 2000 words
Early and late industrialization - Essay Example These late industrialized nations assumed the role of learner ââ¬Ëinstead of the inventor & innovatorââ¬â¢ as their economic and industrial development resulted through ââ¬Å"borrowing and improving technologies which has already [been] developed by experiencing firm in more advanced nationsâ⬠(Do the theories of ââ¬Ëlate industrializationââ¬â¢ explain national differences in the institutional and organisational characteristic of contemporary business? How do these ideas help to explain variations in economic performance?). However, one can notice that the economic growth of the late industrialist nations have been more rapid as they heavily depended on the successful models of institutional and organizational foundations tested by their forerunners. It was the American economist Abramowitz who coined the terms ââ¬Ëforging aheadââ¬â¢, and ââ¬Ëcatching upââ¬â¢ to refer to the industrial and economic progress achieved by early and late industrial nations. Even though Britain forged ahead in the late 19th century with the new industrial revolution, USA, Germany and Japan caught up and even surpassed Great Britainââ¬â¢s achievements in many respects. According to Shin (1996), ââ¬Å"the existence of forerunners has both complementary and competitive aspects to late comersââ¬â¢ developmentâ⬠: the late comers can benefit heavily from the successful models of the forerunners, but ââ¬Å"they have to develop facing formidable competition from existing forerunnersâ⬠(p. 2). The author is of the opinion that there have been only two instances of forging ahead in the modern industrial history-one by Britain in the late eighteenth century and the other by USA during the first half of the 20th century; he believes that the process of ââ¬Ëcatching up had a much greater impact than forging aheadââ¬â¢ in the growth of the world economy (Shin, 1996, p. 2). There is a close link between the nature of corporate governance and the industrial or economic development of a nation.

The Capital Budgeting Method Term Paper Example | Topics and Well Written Essays - 1500 words
The Capital Budgeting Method - Term Paper Example It should be noted that in the assessment of the profitability of an investment, it is also important to consider the timing of cash inflows. The rationale behind this is expressed in the concept of the time value of money which is widely recognized as one of the single most important concepts in financial analysis. This tells us that a dollar to be paid today has a higher value than any dollar to be paid tomorrow. Holding a dollar has an opportunity cost in terms of interest.à Thus, a dollar invested today can be turned into $1.10 next year when lent at 10% interest. In the same way, a dollar collected today will be used by a company to be invested in its profitable undertakings which can yield more dollars in the future. Thus, it can be deduced that investments which generate more cash earlier in their lives are more profitable. This might sound consistent with the payback period. However, it should be noted that NPV takes into account the total cash flow generated by the invest ment and does not stop when the total investment is recouped. à à à NPV, unlike the payback period, recognizes the importance of a companyââ¬â¢s present return on investment. It should be noted that when the company calculates the return on investment using NPV, it measures the cash flow based on the cost of capital. The payback period, on the other hand, only looks at the earliest possible time the investment is recouped and not at the investments meeting the standard of the company.à à à à à A typical business organization extends credit to the customer for various reasons. It is often uncommon to find a company which collects the totality of payment for its products and services in cash.à It should be noted that extending credit exposes a business entity to risks of default. Unlike cash which ensures the full and ready payment of the companyââ¬â¢s goods and services, credit only gives the customer an obligation. With credit, customers have the right to default for any reason. This leaves companies with receivables which be accounted for as bad debts and can be readily written off.

Language as a badge of identity Essay Example for Free
Language as a badge of identity Essay Language is used every day to communicate with one another but beneath that conversation lies another message. The speakerââ¬â¢s use of language gives listeners insight as to who they are, like a badge of identity on their chest. Australian Englishââ¬â¢s unique phonology and lexicon is recognised globally and distinguishes it from other accents, giving the speaker a clear national identity. Ethno-lects are spoken by a specific group of people who have the same cultural background. These ââ¬Å"ethno-lectsâ⬠not only help express an individualââ¬â¢s identity and separate themselves from the rest, but also assist in bringing together speakers from similar backgrounds; much like a football jersey. Text speak is constantly evolving as lexemes are taking on new changes. Many teenagers and younger children have begun to adopt this in an attempt to identify with others and fit in. Through language, we can get a glimpse of a personââ¬â¢s identity but they can use the same medium to change that identity as well. Australian English is unlike other Englishes in many different aspects, especially phonetically morphologically and semantically. Phonology plays a great role in national identity as it is what creates different accents. The broad, ocker Australian accent with its trademark nasal, flattened vowels is one of the key elements of Australian linguistics that sets it apart from the rest of the world. Diphthongs in lexemes like ââ¬Å"highâ⬠are more rounded, resulting in /hoà ª/. Phonetic features such as these are easily identified as Australian. Slang is another feature of Australian English that sets it apart from others. Replacing suffixes with vowels is a good example of this. ââ¬Å"Afternoonâ⬠becomes ââ¬Å"arvoâ⬠, names like ââ¬Å"Barryâ⬠becomes ââ¬Å"Bazzaâ⬠and by replacing the last element with an ââ¬Ë-oââ¬â¢, the adjective ââ¬Å"povoâ⬠has undergone a word class shift from the noun ââ¬Å"povertyâ⬠. Popular culture has also influe nced Australian English, with ABC television series Jââ¬â¢amie, Private School girl introducing a semantic and word class shift of ââ¬Ëquicheââ¬â¢ (a noun meaning a savoury open-faced pastry) to an adjective to describe an attractive individual. Australiaââ¬â¢s linguistic innovation displays individuality and opposes claims that slang is borrowed from America.à Australian English shows both national pride and identity. Teenagers are at the age when they are starting to establish their identity. Neologisms are created by teenagers to claim a different identity from that of children or adults. As adults become more familiar with these lexemes and their use, teenagers abandon them or alter the semantics and use to maintain a linguistic barrier. A good example of this is the well-known acronym ââ¬Å"lolâ⬠which stands for Laugh Out Loud. As more adults become aware of this lexical item and start to include it in their daily texts, teenagers have brought it into speech as an exclamatory and discourse particle. The case of the letters now also alters the semantics; when typed in lower-case, ââ¬Å"lolâ⬠is sarcastic whilst ââ¬Å"LOLâ⬠in capital letters shows true amusement. It is evident that this constant changing of terms by teenagers is a sign of rebellion and an effort to keep a linguistic barrier between themselves and adults, thus maintaining a separate identity. The malleability of the lexicon is taken advantage of by teenagers to form a linguistic barrier between themselves and unwanted people such as adults and other teenagers who donââ¬â¢t belong in their group. Thus, a unique identity is maintained. While teenagers are constantly seeking to separate themselves from children and adults, they are also pressured to conform to the teenage group. Acronyms such as ââ¬Å"idekâ⬠(I donââ¬â¢t even know) and ââ¬Å"tbhâ⬠(to be honest) are now frequently used lexicon in a teenagerââ¬â¢s text vocabulary due to connotations of ââ¬Å"coolâ⬠and ââ¬Å"modernâ⬠being associated with them. Similarly, whatever was once popular amongst a teenagerââ¬â¢s discourse. In time, it was shortened to ââ¬Å"whatevsâ⬠and this trend spread quickly amongst them as a result of peer pressure and the need to be fashionable. Professor Steven Pinker suggests the reason for this is because ââ¬Å"the coolest kids decide to talk that way and it spreads like wildfireâ⬠. Individuals who wish to associate with others who sit higher on the ââ¬Å"social pyramidâ⬠will pick up their speech habits and wear it as a new badge of identity. Having their own exclusive vocabulary allows teenagers to relate to each other and share the same identity, giving them a sense of belonging to a group. Language can be worn as a badge of identity, giving speakers national,à interpersonal and intrapersonal identity. The phonology of Australian English gives the speaker a distinct accent and, paired along with its unique slang, makes it identifiable across the globe. In order to separate themselves from adults and children, teenagers build a linguistic barrier by creating neologisms and maintaining that barrier by constantly altering lexicon to avoid adults becoming too familiar with them. On the other hand, inside the teenage group is a drive to conform and use similar language in an attempt to fit in with peers and to have a sense of belonging. Language is used as a badge of identity regardless of what that identity is. Bibliography Das, S, 2005. Struth! Someones nicked me Strine. The Age, 29 January. 34. Seaton, M, 2001. Word Up.

Effect of Water Velocity on Erosion Corrosion Behavior
Effect of Water Velocity on Erosion Corrosion Behavior Effect of water velocity on erosionà corrosion behavior of materials usedà in marine conditions Corrosion, among others, is one of the main and considerable causes which is liable for the failure of the equipment and the material used in marine applications. Up to now, the majority of the materials that have been developed for marine applications are carbon steel, copper-base alloys, nickel-base alloys, titanium and apparently stainless steel and its variations such as super austenitic, duplex and super duplex stainless steel. (Meng, 2009) Last decade, the use of composites in maritime industry has also increased. (Jones Summerscales, 2016) One parameter, which influences the extent of corrosion on these materials is the water flow velocity, as a result of mass transfer and other incidents, such as erosion corrosion. (Scheers, 1992) For that reason, they are required to withstand to a wide range of velocities. Water can be either static during shutdown periods or have movement. At low movement speed, the cathode reactants affect the rate of the erosion corrosion process. This most usually brings about higher rates of deterioration, but there are some cases in the case of passive alloys, that this results in decreased rates. Furthermore, the provision of oxygen on the external surface of the corroding metal is extremely dependent on the water velocity. (Chandler, 1985) Oxygen can fuel the cathodic reaction in seawater which can also lead to higher corrosion rates. In conditions where the water velocity is increased, apart from the corrosion arising from the electrochemical process of corrosion, there is also mechanical action with much worse consequences. In other words, high velocity results in enhanced erosion corrosion of the components and the installation parts. The concentration gradients in the bulk of the fluid are destroyed by the turbulent conditions. The action which affects neg atively the phenomenon of erosion corrosion appears in a very thin layer of the fluid which is bordering to the pipe wall. (Scheers, 1992) In addition to, there is also the impingement attack and cavitation corrosion which are more extreme forms of erosion corrosion. Conditions offering high water velocity can be found in tubes, pipes and rotating machinery. Figure 1:Schematic of turbulent eddy mechanism for downstream undercutting of erosion-corrosion pits On this dissertation, the effects of water velocity on erosion corrosion behavior of the materials that are used in marine conditions will be examined. Furthermore, the second part of this project will include the impingement of the water from different angles while the amount of the material loss during the impingement and electrochemical corrosion varies between different angles. Cathodic can be also applied, in order to investigate the effects on the erosion corrosion during the changes in flow velocity. It is very important and crucial to know exactly the effects of velocity because the combination of the electrochemical reactions with the synergy of the mechanical reactions due to the impingement in aqueous environments can cause horrible failures of the metallic components used in industry (Meng, 2009) . In addition there is also great need to know the difference in the number and in the size of the pits while velocity is increased (Wing, et al., 2016), as long as materials have suffered and caused serious accidents before in the marine environment and in the hole marine society. Moreover, pipes are used everywhere in ships and offshore structures, so after the study engineers will construct them with bigger safety and reliability (Jin, et al., 2016). The dissertation I about the experimental investigation of the consequences on erosion corrosion behavior in materials, as long as the impact of the impingement from different angles. Afterwards, an anode will be placed on the specimen to investigate with accuracy the changes on erosion corrosion. The major aim of this project is the accurate plot of the corrosion rates, in comparison with the different flow velocities. What is more, one of the aims of this research is the determination of the difference on corrosion behavior between materials and compare the deterioration process and extent of erosion to them. In other words, erosion corrosion, might not be the same in all marine materials, therefore engineers will have a better indication of the effect on each on of them, because in conditions where high velocity occurs, as the dissolved oxygen controls the rate of corrosion in sea water (Larson King, 1954) . It is still very difficult to choose the most optimum material for a specific job in the current working environment, selecting a more erosion corrosion resistant material. (Meng, 2009) The ongoing protocols for design and selection are extremely basic and are based on empirical service data (Neville Hu, 2001). Moreover, another aim is to compare the degree of electrochemical and mechanical reactions in changing angles. The durability of steels and cast iron and other materials will be further interpreted. Lastly, the removal of the protective oxide film in stainless steels might accelerate corrosion (Bonner, 2016) Many water characteristics influence the rate of corrosion process, like Ph, dissolved gases, temperature, dissolved salts, but the one under consideration is the flow velocity. The effect of velocity on corrosion is also Ph dependent. Seawater is alkaline and it is more at the base side 7.9-9.0 and carbonate ion concentrations increase as ph increases (Sabrowski Silva, 2010). Therefore, in basic or alkaline water, the higher velocities have as a consequence enhanced supply of the cathodic reactant, oxygen. For that reason, the cathodic reaction is stimulated and higher corrosion rates take place, causing erosive damage to the metal surface (Hodgkiess, 2013). According to (Meng, 2009), an increase on velocity has as a result the acceleration of corrosion on behalf of the motion of the fluid, as well as (Neville, et al., 1995) state that the reason of the increased rate of corrosion is the enhanced turbulence and the mixing of water on account of the supply of oxygen. Furthermore, as Giourntas stats in his study (Giourntas, et al., 2015), stainless steels have the ability to abide high flow rates. However, in the presence of solids I seawater the persistence is decreased. It also states the application of cathodic protection as a very important feature. As reported by (Neville, et al., 1999), with or without the absence of solids, the E corr drifts to more positive values, during the impingement. As stated by (Neville Hu, 2001), in places with high velocity and sudden changes in direction because of pimps, elbows in pipeworks etc. higher rates occur. Moreover, as Weber reports in (Webber, 1992) the effects are divided in three categories at low flow velocity, medium and high velocity. In the first category, natural convention is responsible, while at the second corrosion increases but without any significant mechanical effect of flow. During high velocities, the damage mechanisms becomes very complex. In keeping with (Li, et al., 1994), erosion corrosion problems enlarge catastrophically but the outflow of water. In agreement with Lin and Shao, with increasing impingement angles and velocities, the erosion is developing also. The rate of 1020 steel is lower than pure aluminums. During erosion conditions, many mechanisms act but only one or two of them is the principal mechanism. (Lin Shao, 1990) Concerning (Scheers, 1992), the simultaneous effects of velocity and ph have been investigated and turn out that in mild steel, there is an increase in corrosion rate with the velocity of flow, according to the ph value. Not to mention that, L. Wang notices that erosion corrosion increases rapidly with the development of the flow velocity at 14 m/s at 80% HR (Wang, et al., 2016). The dissertation of the effects of water velocity on erosion corrosion behavior of materials is mostly experimental. First of all, all available sources, papers and books will be investigated concerning erosion corrosion on materials that are used in marine condition. Furthermore, the effects of velocity and impingement angle will be searched. Relating the experiment, specimens have to be chosen. Possibly, only the major materials of maritime industry will be selected. These will have a cylindrical shape. Furthermore, those specimens will be placed in a recirculating rig as shown in the figure below. Afterwards, saline water will pass through a pump and therefore accelerate. Water will flow through pipes, where at the end of the piping system, a nozzle is installed, in order for the flow to take the exact preferable velocity. Nozzles will be changed. Directly vertical from the direction of the flow is the stagnation point. In the figure besides is a representation of the region where the liquid jet impinges to the solid material (Neville, 1995). The velocity depends on the diameter of the nozzle. Thence, water will impinge to the specimen causing erosive and corrosive damage. With the use of an equipment, the vertical impingement will change and erosive damage from different angles will be investigated. Afterwards, the exact amount of the material that has been degragated will be investigated through scale and metallography. References Bonner, R., 2016.
