8 Reasons Why Chemical Reactions Are Important

8 Reasons Why Chemical Reactions Are Important Chemical reactions are the most important types of events in the universe. Its through chemical reactions that plants grow, produce fruit, and become compost for new plants. Its because of chemical reactions that human beings (and all other animals) reproduce, digest, grow, heal, and think. But what exactly are chemical reactions? Why are they so important? What Chemical Reactions Are Elements are the basic substances that make up  matter in the universe. Each element is a chemical. Elements that form bonds are called molecules. An oxygen molecule, for example, has two oxygen atoms. Chemical reactions occur when molecules interact and change. Bonds between atoms in molecules break and are reformed in new ways.   Chemical reactions are at the heart of literally every biological process in the universe. Stars form because of chemical reactions; our sun ignited because of chemical reactions in its core. Life developed on Earth as a result of chemical reactions. The circle of life is, at its heart, a series of chemical reactions. Even our ability to think and move is a result of chemical reactions that occur in our bodies. 8 Reasons Why Chemical Reactions Are Important Chemical reactions are the reason we exist on the Earth, and, of course, they are the reason we are able to ask questions. In addition: Chemical reactions are how new forms of matter are made. While nuclear reactions also may produce new matter, nearly all the substances you encounter in daily life are the result of chemical changes.Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties. These properties can be used to identify an unknown specimen or to predict how different types of matter might react with each other.By observing chemical reactions, we are able to understand and explain how the natural world works. Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more.Exciting and entertaining chemical reactions pique interest in science. These types of demonstrations encourage people to ask questions and may lead them into science-related careers.Chemical reactions help us to solve crimes and explain mysteries. B y analyzing blood and tissue samples, for example, police are able to identify the perpetrators of crimes. Chemical reactions are also the tools we use to date fossils, analyze ancient materials, and better understand how our ancestors lived. By observing chemical reactions in outer space, we are able to identify and describe other planets. We can even determine which planets and moons are likely to be able to sustain life.Fire, the most important discovery made by human beings, is simply a chemical reaction.Without chemical reactions, nothing would ever change. Atoms would stay atoms. New molecules wouldnt form. No organisms could live. If matter didnt react with other matter, the universe would be extremely boring!

A comparison of Cousin Kate by Christina Rossetti, and The Seduction by Eileen McCauley Essays

A comparison of Cousin Kate by Christina Rossetti, and The Seduction by Eileen McCauley Essays A comparison of Cousin Kate by Christina Rossetti, and The Seduction by Eileen McCauley Paper A comparison of Cousin Kate by Christina Rossetti, and The Seduction by Eileen McCauley Paper Essay Topic: Christina Rossetti Poems Literature The poem Cousin Kate by Christina Rossetti tells the story of a young maiden who is attracted to a lord who tempts her with his riches and then uses her. The lord is then attracted to another women Kate. He abandons the pregnant girl for Kate. But Kate refuses to have anything to do with the lord unless they are married and so the lord marries her. They then try for a child but are unsuccessful because Kate is infertile. By this time the maidens son has grown and so when she hears of the couples news she boasts of her son. The poem The Seduction by Eileen McCauley describes how a girl meets a boy at a party where they dance and talk all night. He then takes her to a riverbank where he takes advantage of her drunken state and sleeps with her. They do not speak with each other again after that night and three months later the girl discovers she is pregnant. She loses her friend sand is rejected by society as a result of her actions that night. Cousin Kate is set in the countryside where the maiden grew up and was hardened by the sun and air. She was contented with her cottage mates, which showed her youth and innocence. The scene then changes when the lord lures her to his palace home. Because she is plucked from her poor life to live in luxury this gives the story a fairy tale feel to it. Although the story has quite a sad theme the settings for this story reflect the fairytale ending. The Seduction is set in the city late at night to start with its silver stream of traffic, it then moves to Birkenhead docks and the Mersey, green as a septic wound. The descriptions of these places are not pleasant or nice to imagine which encourages people to expect a sad or at least unpleasant story. The settings are quite depressing to imagine and they help to emphasize the despair that the girl is feeling in her dilemma. The fact that everything appears to have gone wrong for the girl matches perfectly to the idea of a filthy city. Both the girls are young although we do not know exactly how old the cottage maiden is, we do know that the girl in The Seduction will miss the summer of her sixteenth year. The girls are so young because it encourages the audience to feel more sympathetic towards the girls and their dilemmas that have occurred. Cousin Kate is written in the first person, who gives the effect that, the maiden herself is telling the story, which makes the story feel more personal to the listener, they feel more involved. Because the poem is written in the first person it seems more like a story and so people will not necessarily take on board the message behind it. Where as The Seduction is written in the third person because the author hasnt personally experienced the event, but wants to relay the event to the audience. Because the poem is written in the third person it possibly encourages the audience to think about the issue described and how it may be affecting people around them. There are several similarities between the two girls, even though the poems were written 100 years apart. Both the girls recognized their loss of innocence after their experiences. The girl in The Seduction cried that she had missed all the innocence around her, which shows that she is full of regretful for the events that had happened. The maiden describes her self as an unclean thing that might have been a dove, doves were a symbol of purity so this shows that she realises the mistake she made, and that if she were to have waited a little while longer then the other villagers may have still viewed her as pure. They are both aware that they have been lied to and used but the maiden feels that the Lord has used her whereas the girl in The Seduction feels that she has been cheated by the promise of it all from the magazines. The people who live around them reject them both. They call the maiden an outcast thing and the girl is told she always looked the type. Both the girls are ashamed of what has happened to them and feel that they lived a shameful life and have fallen into a despicable feminine void. There are also several differences between the girls and the poems. The girl in the seduction does not feel jealous, neglected or superior and she does not have any mixed feelings, whereas the maiden has all of these. She is jealous of her cousin and feels neglected when he chose her and cast the maiden by, and she feels superior to her cousin when she has her fair- haired son (her gift). In The Seduction the poem has 15 stanzas, there are 4 lines to every stanza but the 9th is 8 lines. This is because it is the most important stanza, and should have the greatest effect on the audience. In Cousin Kate there are 6 stanzas each with 8 lines, this is to keep the rhythm of the poem flowing. The most important part of poem is the ending and so it can still have a dramatic effect without having its structure changed. Both the lord and the boy are simply after the girls bodies. You can tell this because the boy is not seen again after the incident and the Lord changes his women often which shows that he does not get emotionally involved in them. They go about getting the girls in very different manners. The lord flattered and praised the maidens flaxen hair. He also tried to buy the maiden with his land and offered to lift her from mean estate to sit with him on high in his palace home. He is not a faithful or honest man and changed his women like a glove; he liked to have a woman on his arm to show off like a silken knot, the maiden feels that the lord fooled her. The boy does not seem to be very well educated eating me dinner and he does not appear to have a high position in society. You are given this impression because a man with a high status would not taste of nicotine or have a bag filled with shimmering sweet paint thinner. He does not have lands or great amounts of money to entice girls with, and so must use another method to attract the girls. The boy flatters the girl by dancing with her all night. He also bought her drinks until the girl was so drunk on vodka that she wouldnt refuse anything. The treatment of the maiden by the lord is often compared to that of old or discarded clothing; he changed her like a glove shows that the lord did not actually care for her. The maiden is compared to a toy, a plaything, which shows how the lord treated her, she distracted him for a little while before he saw her cousin and was then attracted to her instead. She is also compared to a dove, which is supposed to symbolise purity and virginity and so the use of this imagery demonstrates how she would have been without the lord. Christina Rossetti also says that Kate had the stronger wing to show that the maiden feels that Kate stole the lord from her, she won the fight. McAuley makes several comparisons to a wedding because a wedding is a happy and romantic occasion, which is what the girl wanted, but what the actually happened to the girl was very different to how she had first imagined. She then describes the Mersey, green as a septic wound, which gives the impression that this story is not going to be a happy one. The maiden repeats closer to emphasize how proud she is of her son. She asks, Why did a great lord find me out? twice, which shows that she did not realise that she was attractive and shows that she was innocent. The girl in The Seduction was truly, truly frightened which calls attention to how afraid she really was. She also repeats herself again saying stupid, stupid promises which shows how foolish and naive she feels she has been by believing the boy and all the teen-age magazines. She repeats herself one last time repeating, turn away, move away, fade away which shows how desperately she does not want to be in this situation. Wide blue eyes are mentioned twice, which would have been used to show the innocence of the girl before the seduction took place, after the incident blue eyes are not mentioned at all, which shows her loss of innocence. In Cousin Kate the main contrast is the treatment of the two women by the same man. The lord treats the maiden despicably but treats Kate with far more respect and care. This is most likely to be because Kate made him marry her first before having anything to do with him, which shows that she is more mature and is willing to offer a far greater commitment to the lord than the maiden did. Because the maiden was willing to simply be his girlfriend he believed that it was acceptable to treat her in such a manner. In the Seduction the main contrast is state of the girl before and after the incident, and also between how her future should have been and how it now will be. The girl was happy and enjoying life before the incident she met him at a party and hed danced with her all night. And she had been looking forward to her sixteenth year with day trips to Blackpool and more. But now she is unable to do any of that. The girl is almost suicidal by the end of the poem Better to starve yourself like a sick precocious child. Showing how badly she feels about her situation. The cottage maiden was treated horrifically by the lord, and it was very cruel of her cousin to agree to marry the lord, when she new how her cousin felt towards the lord. But the maiden did have a son, and she is extremely proud of her son and appears to be happy now that she has her son with her, so her fate was not awful. The boy took advantage of the girl in The Seduction. She was then completely rejected by society. She was not given the consolation of having a son to encourage her; at the time she had lost everything that was dear to her. Because of this I felt more sorry for the girl in The Seduction than for the maiden in Cousin Kate because at least the maiden had her son, the girl had nothing. Also it is easier to understand a persons situation in a time closer to your own than it is to understand a person from over 100 years ago. It was easier for me to sympathise with the girl in The Seduction because one of my friends has been in a similar situation, so I had a better understanding of the situation. In conclusion I found both the poems interesting to read and discuss and both the poems had an effect on me, as I felt extremely sorry for both the girls, as I believe that it is wrong for anyone to be treated in such a manner. Both the poems were easy to follow and to understand although they did prove to be difficult to analyse because it is hard to describe what is meant by all the metaphors and the like. Overall I enjoyed this piece of work as it was both interesting and challenging.

Ethical Issues - Essay Example Computers and information systems have become part of human lives and, as a result, have created an opportunity for abuse and misuse hence raising the issue of ethics (Haag & Cummings, 2013). There is an ethical issue relating to the privacy of personal information and increasing concern about storage and access to personal details (Haag & Cummings, 2013). The risk of losing individual privacy affects information system because some people are unwilling to transact online for fear of exposing personal details to unintended persons. On the other organizations are incurring a lot of expenses to protect clients details from unauthorized users. Although organizations cannot fully prevent unauthorized access clients information, they can limit the accessibility by installing security details such as data encryption and use of passwords (Haag & Cummings, 2013). In conclusion, the use of information technology and systems has both positive and negative implications in the society. Although it has improved interactions of persons across the globe, it has caused ethical issues such as loss of privacy through unauthorized access to personal details. Organizations should improve protection of personal information. However, organizations should provide their clients with training on what information they should share and how to protect their privacy against unintended

The Australian Automobile Market Essay Example | Topics and Well Written Essays - 2000 words

The Australian Automobile Market - Essay Example Videos of new launches and product features should be hosted on YouTube which would draw an attractive viewership. Traditional mass media advertising has to be maintained through TV, radio, Billboard advertising and outdoor advertising. Distribution channels should be both direct and indirect. The direct channel should be through the internet which would allow the customers to place orders, make suggestions, see the presentations, and customize their own vehicles. The indirect channel through the dealers is necessary as many would first like to physically see the product before ordering it. Thus a change in the marketing mix can help the company to face the challenge of the downturn. The car sales in Australia have been steadily decreasing throughout 2008. Recorded sales of the automobile industry in November 2008 were lowest for five and half years.

Self Reflection on Developing Confidence

Self Reflection on Developing Confidence Competence is difficult to measure and define because it is a complex concept (FitzGerald et al., 2001). As many people wrongly think, competence is not simply the satisfactory performance of a set chores; competence is much wider than that. Australian Nursing and Midwifery Council (2011) defines competence more extensively as the putting of skills, knowledge ,attitudes, values and power to perform that base productive and or better accomplishment in a professional area. Competence is one of the five main constructs of caring behaviours. To be able to demonstrate caring attitude as a well-trained professional nurse, one must first be a competent practitioner of the nursing profession. For a nurse to be fully competent there is the need to have a sound knowledge based on my area of specialty in other to function independently with confidence. Smith Straham (2004) identifies that the ability to teach requires considerable amount of confidence in ones professional career. A nurse who lacks confidence as a tutor is not probable to give up control of the ward or classroom to students. High self-efficacy is also really needed from me as tutor. One most significant aspect about teaching is that it also helps you develop your knowledge. Feeling unsure and uncertain as a nurse is not a good quality, I need to gain confidence as well as I have gained experience. As a staff nurse teaching student nurses is an important part of my duty, student will always turn to me for assistance and guidance in clinical care. Normally student nurses find it easier to approach newly registered nurses to ask for support and counselling. RELATING MY SKILL TO SECTION With latest exclusion of stimulated experience, traditional methods to clinical education in nursing have not been changed substantially for years. In this olden model, faculty instructors give instructions and evaluate learning for a group of 8 to 10 students and work as clinical experts and supervisors for them. Patient assignments are always received in advance and clinical experiences are planned for by reviewing procedures, pathology, drugs and nursing interventions. When teaching I interact with the student through the patient assigned to them but I lack confidence which is unprofessional. My priority though is my patient care first and the learning student a secondary concern. Their primary relationship normally is with faculty members. My duty also as a tutor in the ward is to work simultaneously with the students each day. Sometimes the presence of students in the ward can be seen as burdensome and interferes with my ability to provide patient care. Raines (2006, Pp. 8) stressed that nurses make a huge difference in also helping students have clinical competence and skills. When student nurses are allocated to staff nurses they begin to appreciate the full range of professional nursing roles and responsibilities but in a case where the staff nurse assigned to a student nurse lacks confidence what would the student feel? Clinical practice competence and skill competence both relies on role competence (ORourke, 2006). COMPETENCE AND NMC (NURSING AND MIDWIFERY COUNCIL) The National Council of State Board of Nursing (2005) defines competence as the power to act and apply Knowledge, interpersonal, directing and psychomotor skills to nursing practice role.Tiley (2008) noted that there is no definite and welcomed definition of competence in nursing education and practice. Notwithstanding competence is defined in unlike ways, there is a common goal: to guarantee nurses have the information, skills and power to perform duties expected and required for their practical settings. The word competence is acquired from Latin and it means having important qualities and abilities to function in a distinguishing ways. Nagelsmith (1995) explains the basis of professional competence as a set of vital and appropriate knowledge, skills and attitudes. There are different essential features needed to achieve competence: Perseverance of Knowledge, skills and abilities needed for graduates of nursing education programs, based on principles and legal necessity; Pertinence to current practice; Registration and licensing examinations by board of nursing; Board of nursing persistent education requirements for licensing; Employer watching carefully of required staff development modules, finishing of courses, demonstrations and examinations; Guidelines and accreditation for nursing practice. In addition, competences are required in practice as a profession because it is needed to always exercise ones professional responsibility and practice. Nursing and Midwifery council (NMC) included competence as a constituent in professional practice because as a professional you must keep your skills and knowledge current throughout your working life. Specifically you should take part as a matter of usual practice in learning activities that grows your competence and accomplishment. To practice capably in learning activities that develops your competence and performance. To practice capably one must have the knowledge, skills and abilities needed for lawful, safe and productive practice without direct supervision. One must recognise the extent of his or her professional competence and only attempt practice and accept responsibilities. It was also stated that if an area of practice is beyond ones level of competence or outside your area of specialization, you must get help and supervision. One also has a responsibility to assist the progress of students of nursing, midwifery and health visiting and others to cultivate their competence. Having accountability to deliver care based on current proof, best practice and where appropriate, validated research when available. RATIONALE WHY I NEED TO DEVELOP COMPETENCE IN THE CHOSEN AREAS Safe nursing practice in my chosen area, mental health at this level is typified by the use of nursing process to treat people with truly existing or potential mental health problems or psychiatric disorders to: advance and promote health and safety I should be able to evaluate dysfunction: help persons to get back or improve their coping abilities, increase strengths and stop further disability. In contributing to safe practice to the people in the society i have to develop my competence in a wide sphere of interventions ,including health promotion and health maintained plan of action, intake screening and assessment and triage, case management, milieu therapy, promotion of self care actions, psychobiologic interventions, health teaching, giving advice, critical situations care and psychiatric restoration. The nurse maintains accountability for maintaining competence in this area of mental health nursing practice through life long learning. Competence is an essential component in my professional responsibilities. Professional responsibilities also need me to recognise limitations and put myself in settings and duties that allows me to function safely. Minimum vital competence for safe practice is also essential for me they include essential features such as basic principles of nursing, critical thinking, interpersonal relations and areas of ethics. There is a lot of risk involved working as a mental health nurse; preventing suicide depends on the nurses ability to know about a persons suicidal risk status. In most cases mental health nurses are the most competent to attempt a full risk assessment of a suicidal patient. The general health professional is frequently placed in place of activity where potential patient suicide risk is sure through direct account from the patient, noting of behaviour or from patient history examination. In this clinical place of activity, the general nurse or allied health professional responsibility is to carry out a brief risk assessment and then refer to the suitable mental health professional for an inclusive psychiatric assessment (Department of Health, 2004). SELF ASSESSING AND MAINTAINING COMPETENCE IN THE CHOSEN SKILL In the field of nursing competence is required for nurses to make safe clinical decisions. Other methods for evaluating competence include self-assessment and the development of professional portfolios. The usefulness of self-assessment has helped me to maintain and improve competence in the aspect of teaching student nurses who wants to learn more in the area of mental health nursing. My individual competence has improved as I become more experience and the knowledgeable. In complying with my duties as a mental health nurse in supporting other skills development i will participate in team meetings where equal opportunities are given to share knowledge and ideas with colleagues. I will also engage in a teaching programme either as an instructor or a study under a preceptor. In addition improve my clinical practice by with self or others.

Chapter 25 of The Grapes of Wrath by John Steinbeck Essay -- Grapes Wr

Chapter 25 of The Grapes of Wrath by John Steinbeck In the twenty-fifth chapter of his novel The Grapes of Wrath, John Steinbeck presents the reader with a series of vivid images, accompanied by a series of powerful indictments. Steinbeck effectively uses both the potent imagery and clear statements of what he perceives as fact to convey his message. This short chapter offers a succinct portrayal of one of the major themes of the larger work. Namely, the potential bounty of nature corrupted and left to rot by a profit-driven system, a system that ultimately fails. Steinbeck begins the chapter with the simple statement, "The spring is beautiful in California" (p. 346). The proceeding explanation of California’s springtime beauty evokes images of Eden and Paradise. Steinbeck describes the full green hills, fragrant valleys of fruit blossoms, the swelling tendrils of grapes, and mile-long rows of lettuce, cauliflower, and artichoke. The fertility of the land is explicitly conveyed by the sentence, "The full green hills are round and soft as breasts" (p. 346). "Round and soft" breasts bring to mind both the voluptuous figure of a fertility goddess, and the comfort and safety of a mother’s embrace. The images that Steinbeck puts down here portray California as an abundant Eden. Capable of providing for all of her children, just as a mother would. California’s bounty is graphically depicted when Steinbeck says, "The fruit grows heavy, and the limbs bend gradually under the fruit so that little crutches must be placed under them to support the weight" (p. 346). Imagine a hungry man reading those lines! Fruit so large and full that the branches bend and must be supported by crutches. It is as though Steinbeck has just describe... ...he yield of the harvest. Yet there is a failure that Steinbeck perceives. He sees the hungry and starving people. How is it that despite the achievements of the best and brightest of humanity there still exist starving children? The answer that Steinbeck implies in the course of the chapter is that it is the system that is to blame. Any system of commerce that utilizes the best of human knowledge and pools the resources of humanity in its drive to make a profit, but is unable to prevent a child from starving to death, is a failure. It is a great and despicable failure in Steinbeck’s eyes. "There is a sorrow here that weeping cannot symbolize" (p. 349). Works Cited Ovid, Metamorphoses. ("The Ages of the World.")
