Principle Events in the Evolution of Earths Atmosphere essays

Principle Events in the Evolution of Earth's Atmosphere essays The literal translation of the word atmosphere is "sphere of vapors." The Earth's atmosphere is a protective sphere of vapors or air that surrounds the Earth and provides it with a layer of insulation from the harmful rays of the sun. It is a vital part of the Earth and has changed dramatically since the beginning of time. The earth's atmosphere had gradually changed since the Earth's birth approximately 4.6 million years ago. In the beginning, Earth's composition was very different than how it exists today. A long time ago the Earth's atmosphere was very similar to today's Venus and Mar's atmosphere. It had about 95% carbon dioxide, 2-3% nitrogen, and very little, less than 1% oxygen. Today the Earth contains 79% nitrogen, 21% oxygen, and 3% water vapor. It is evident that many events happened over billions of years that have contributed to this change in the Earth's atmosphere. Earth had developed so drastically because of the large amounts of dust and gas cloud within the Milky Way galaxy. The Earth grew larger as huge meteorites hit it, and the surface was covered with dust. Volcanoes began to form and emitted lava, ash, and most importantly gases. Carbon dioxide, water vapor, and nitrogen were released into the atmosphere from the volcanoes. This process is called outgassing and took place within the first million years or so of the Earth's formation. Then, about 4 billion years ago, the planet cool ed, and the outgassed water vapors condensed into clouds. It rained and produced the oceans, and even enough to cover 95% of the Earth. Also, because it rained, there was less carbon dioxide in the atmosphere. The carbon dioxide was lost over billions of years, as the ocean formed there was a chemical reaction in which carbon dioxide and water formed carbonic acid. It is shown in the equation CO2 + H2O = H2CO3. The carbonic acid dissolved oceanic rock into sand, silt, and mud. It is evident because of this geochemical process occurre...

Evaporator Mass and Energy Balance, and Mechanical Design Essay

Evaporator Mass and Energy Balance, and Mechanical Design - Essay Example As the discussion outlines that evaporation is a plant operation used to concentrate a solution or a liquid of a nonvolatile solute and a volatile solvent, which many at times we use water. A portion of the solvent is vaporized to produce three products i.e. concentrated solution, slurry or thick and viscous liquid. Evaporation can be confused with drying but it differs from drying in that the residue is a flowing liquid instead of a sticky solid material. Evaporation on the other hand is different from distillation in that there is no deliberate attempt to separate the vapors into individual components.This essay highlights that evaporation is one of the most energy consuming processes within most industries including dairy, food and chemical industries, it is most essential that evaporation be approached in regard to economical energy utilization and effectiveness of the process. In addition, evaporator should be safe to operate and offer no negative environmental impact. It is pos sible to achieve the above when equipment manufacturer is able to offer a full selection of evaporation technology and systems developed to accommodate various product characteristics, the percent of concentration required, and regional energy costs.  Achieving control of most chemical/industrial evaporator systems is quite simple. However, with hygienic evaporators the control is somewhat more complicated due to the need to start up, operate, shut down and then clean at quite frequent intervals.... per P&ID Piping and Instrumentation Diagram PHA Preliminary Hazard Analysis PLC Programmable Logic Controller MP Main Product PNCB P-Nitro Chloro Benzene DFC Direct fixed cost Table of figures Figure 1: Multiple effect evaporation with thermo-compression Figure 2: Simplified flow diagram of Evaporator of pharmaceutical plant Figure 3: Relationship between evaporation ratio (e) and concentrations of Feed (Products) and concentrate (GEA 2012).

What Page are James Carnells Essay in Real Reading and Writing?

What Page are James Carnell's Essay in Real Reading and Writing?JAMES CARNELL'S ESSENTIAL ON WAR was a topic that this year's Dialectical Liberal Forum has focused on. While just another speech delivered to the same audience, the same students, they found it to be so incredibly focused on its subject that it actually motivated them to truly think about war and its effect on our lives.This year the 'What Page is James Carnell's Essay in Real Reading and Writing' in which Carnell addresses the subject of history, politics, morals, and ethics. And I am not just talking about historical or political topics as the course was very much about moral questions.The discussions were led by four students, Ralph Della Riva, Colin Wilson, and Sabrina Thompson. They each had their own contribution. The presentation was very well done and included a few points of interest but there were some points of interest that was lacking.For example, the pace and the focus of the 'What Page is James Carnell's Essay in Real Reading and Writing' fell on 'Civil War and American Culture.' The talk veered between the civil war and American society and the way these two things have a relationship to each other. The main points that Carnell made were that the Americans were coming from the culture of the South, the Christian denomination and the Bible; that the soldiers they were fighting against were Protestant, white, and very religious and did not show any concern for the rights of the Catholics or the non-Christians.So what I think this is missing is that there was not a whole lot of actual research or even quoting of primary sources. He discussed the psychological and mental psychological effects that we would have of war but did not touch on that particular issue as far as inbreeding, alcoholism, or food for the people in the United States.He does touch on how the war in Iraq and Afghanistan has a very different perspective on history and how these questions need to be addressed. We need to look at our history and how it is affecting us and it seems that Carnell fails to address the historical and cultural perspective that is vital in these discussions.I know that the course was less than interesting to me and there was a lot of discussion that was uninteresting, but the real point here is that the students should do more in their course and their lectures. While the lectures were brief, they were very well written and captured the discussion at the right pace.

Personal Statement for the University Example | Topics and Well Written Essays - 1250 words

For the University - Personal Statement Example Studying an undergraduate degree on Accounting and Finance in University of Exeter gave me greater insights into how the subject and the function of accounting within business help to define the process. During my first year compulsory modules, Business Law for Accountants, I understood and demonstrated knowledge of the legal systems in the UK and the principle features of business law. The Hong Kong legal systems are based on the UK system and so although this module was UK-based.Knowledge of the law can help me in dealing with unexpected difficulties. During my holiday in 2011, I have travelled to a new villa in the Maldives for vacation with my friends. During this 1 week holiday, my friends and I were promised by a travel agency that there was a bar and English speakers on premise. However, when we arrived, they spoke very poor English and the bar only opened once during the week. As such, we are very disappointed with the journey. When I came back to Hong Kong, I filed suit agai nst the travel contract by applying the case "Jarvis v Swan Tours (1973)" which I had learned in my business law module. Finally, I held to be entitled to damages for my disappointment. As a result, I received 1/3 of the cost of my holiday as well as receiving â€Å"disappointment damages† for the holiday. Due to the fact that I was able to apply the case law I was familiar with in order to positively affect my own life as well as the life of my friends, I have become greatly more interested in better understanding the nuances of the law.

Solving Communication Problems: Reflective Essay

Solving Communication Problems: Reflective Essay PROBLEM SOLVING AMITA KHOWAJA JODY STONE Problems are at the center of which every day many people deal at their work. I got a chance to deal with a problematic event when I was on my shift, I was assigned with the client who was living with his family. My core responsibilities are to assist client in bath and in her daily living activities but the client want me to do house work and she want to take help from her daughter for the bath. The problem with this scenario is as per my job expectation I must assist client in all of her activities in order to make sure that the care she is receiving is safe and comfortable but my client is expecting from me to do more of the house work like vacuum, dust and wash the floor so that she will not feel like a burden on her son. The area for which she asked me to do housekeeping is mostly used by other family members. When I contact my supervisor, she advises me that my agency does not have a strict definition of light housekeeping but if I took any additional time to complete the work she cannot give me any extra wages for the additional time spend on the shift. So, I decided to solve this problem through problem solving process and I identify that the situation I am going through will affects me and my client because if I say no to my client it makes her upset and might be noncooperative with me which in future become a barrier in my communication level with the client as well as hinders in developing a therapeutic relationship with the client. If I say yes, then might be I will have required additional time and energy for it. Moreover, I will not be getting any extra wages for extra time. The situation will definitely make me concerned firstly, because the client want to take help from her daughter for her bath and I am not sure about the daughter willingness to give her bath furthermore, I am not sure if the daughter knows the skills, knowledge and techniques to give a safe and comfortable bath to the client. The time of the client bath may be a good time to do lot more observation and encouragement to make client independent as much as possible. The health care personals are well trained in performing that observations and encouragement. Client assessment starts from the scalp and proceed to the feet for any kind of abnormal skin condition, any lesions, swelling or any sign of altered circulation and then based upon that assessment appropriate interventions were planned. There is a lot more chances that the client daughter fail to do significant observations during the bath and missed any changes which risk the client health. My second concern is about client though ts that she doesnt want to feel like burden on her son so need to rule out the reasons behind it. The third concern is if I say yes to client for doing housekeeping then it will affect one of my social determinant of health that is employment and working condition. Intense working conditions and excessive hour of work cause me bodily pain, increase chances of injury and other physiological and psychological symptoms which ultimately affects my personal relationships. My client rather than asking her family members to do their home housekeeping she is asking me to do for her give me the impression that my client health determinant of social environment is also affected. Because of all these reasons I feel that the situation requires immediate attention to resolve the issue. I analyze the scenario and identify that the situation highlights the unknown, need to be identified problem where interventions are required to resolve the problem. The situation also highlights the affective problem where person emotions are significantly involved so my decision of saying no for housework to the client will greatly affect her emotions. According to Chaudhuri, A. (2014). A person job should be such that he/she can maintained a balance between important aspects of life. A person work should not increase stress level and he/she able to spend quality of time with family after job hours. On my end the scenario also highlights the work-related problem because my decision of saying yes hinders me in balancing my work and my family life.ÂÂ   Moreover, I also feel that there is an interpersonal communication gap between people involved in the scenario that are my client and her family members so, further digging is required in order to rule out the root causes of the p roblem. I will start handling the problem on my end by maintaining all the behavioral characteristics of communication and use the assertive style to reply my client. I will reply I can see that this is important to you, and it is also important to me as well. I am assigned here to deliver you as much as support but there are certain things which I cannot do such as vacuum, dusting of most of the area use by other family members. I understand that this will make you upset but we can talk more respectfully to each other to make the situation better for both of us. I appreciate if you discuss with me about what bothers you for not asking your family members to do the housekeeping of the house this will help me to resolve your problem. In this way, both of us maintained the respect and there is fewer chances of emotional outburst. I will further analyze the problem by asking questions from client about her family members to understand her family dynamics. I will ask the client about the education of her daughter to identify her literacy level, this will help me in understanding what level of teaching and information I need to deliver the daughter so that she can maintain safety of client during bath. I will ask the routine of her daughter to rule out her availability and willingness to give bath to the client. Moreover, I will ask client what kind of relationship other family members are having with my client and with each other, how frequently they sit together and spend time with each other, if my client want to share anything who is the most reliable person in the family with my client feel to share her problems and feelings this will help me understanding the social environment of the house. Additionally, I will ask client their source of income to identify the economic status of the family which will help me in sharing the option of hiring a housekeeper for few hours to do house work. I will develop an action plan to solve the problem by identifying several client needs for example as I was newly assigned staff with the client so she will be feeling anxious and worry working with me. In addition to it she is also facing difficulty communicating her true feelings and concerns with her other family members. There is also a need of division of household task among family members or need to hire any part time housekeeper for vacuum, dust and washing the floor. Besides, my clients daughter also need teaching about proper techniques of giving safe bath to the client. According to me the first priority is to reduce my client anxiety and apprehensions by properly orienting myself and my role, remain be calm and answer questions about the information which my client needed. This will create a positive significance and help in reassuring client that I am here to help her. In this way, my client move from negative emotional level to positive level and she feel comfortable and ready to work with health care member. My second priority is my client should get safe bath. My client want to take bath from her daughter so I will respect her decision and to complete this priority I will ask my client daughter if she is willing to give bath or not, if she is willing then I will have taught her all the safe techniques to be followed, and observation made about the client body for any kind of health-related issues during the bath. After teaching I, will supervise the daughter giving bath to my client to observe whether she is following the right techniques and p rovide feedback upon it. This will positively help in preventing my client from any health-related complications. My third priority will be to enhance communication among the family members. I will achieve this priority by focusing on my client by asking her questions about her children and other aspects of their personal lives, this give her message that I am interested in her as a people rather than as a client. Furthermore, encourage my client and her family members to be open to discuss issues, problems, thoughts and feelings with respect, love and trust. Spend quality time together so family relations become stronger and good communication will be enhanced among family members. They should equally and properly divide house work among each family members so burden will not be upon one member of the family. The positive consequence of good communication among family will help to efficiently cope with life challenges. I have chosen the above action plan because by doing proper assessment and observation during bath will help in early identification of health-related conditions and early consultation to the physicians, in this way my client physical health will be enhanced. By developing therapeutic relationship with client help client to adjust with change that is working with a new staff will enhance her emotional health. Additionally, good communication among family will also enhance emotional and social health by allowing self to cope with stress, help in learning, managing conditions and live in harmony. Mine occupational health will also be improved as I will get manageable work load. I will be evaluating my action plan by monitoring and discussing feedback with my client about the effectiveness of strategies that are discussed with the client and family members and their satisfaction level upon it. I will do conclusion by evaluating myself that what I have accomplished at the end and how this experience of solving problem develop me professionally. After resolving the scenario, I will report back to my supervisor about all the efforts that I have made to resolve the issues so that she can guide me about what I have done good and which aspects will be done differently in future. I will use my communication skills of pumping the negatives and owning to ask more about negative feedback which will give me more opportunity in order to modify my behaviors in future.
