Mathematics Competition At An Early Age - 1089 Words

With a strong desire to challenge myself and a thirst for innovation, I started participating in Olympic Mathematics Competition at an early age -- an area full of new ideas, challenging problems. Mathematics is said to be a male-dominated area, nevertheless, I wanted to show that it is wrong. From elementary school to high school, I enjoyed my summers with intensive training on nationally renowned mathematical competitions. While the medals I earned in mathematic competitions have opened up doors for me in middle school, high school, and then college, the knowledge and experiences gained from years of unremitting dedication to the craft of problem solving has proven to be the most rewarding result. I became eager to explore my potential, and have no fear for failure. My talents and persistent effort enabled me to get full score in National Middle School Mathematics Olympiad and be the only junior high student in my school to win the first prize in National High School Olympiad. In t he summer of 2011, I was selected to represent my province to take part in the Chinese Girl’s Mathematical Olympiad (CGMO). The days being with girls from all around the world revolutionized my way of thinking. I was impressed by the elegant solutions provided by those girls from other countries and their enthusiasm towards perfection. This motivated me go abroad to study with those talented minds.

Essay on Journal Entries on the Kite Runner - 1306 Words

QHSS Vikas Peddu Journal entry #1 In the first ten chapters of The Kite Runner Khaled Hosseini focuses on the theme â€Å"Friendships take years to build, but only moments to destroy†. For example, Amir and Hassan have been friends since they were born, they built their friendship until the day of the kit fighting tournament. When Hassan ran the runner ups kite he ran into Assef, who was seeking revenge for being insulted by Hassan earlier in the year. Assef deemed that rape would be a proper punishment for the insult. Unbeknownst to Assef as well as Hassan Amir was watching everything. If he wanted to, he could have intervened and stopped his revenge but chose to watch instead, ruining his friendship instantly. Ali and†¦show more content†¦When Hassan got raped Amir did not do anything, most likely out of the fear that Assef would do something equally as bad (or worse) to him also. Ever since that day Amir has been seeking redemption from Hassan in many different ways, such as making Hassan pelt him with fruit. That did not work though because Hassan respected Amir so much that he could not throw fruit at him. The main conflict in chapters 11-23 is Amir feeling guilty for not helping Hassan when he should have. The story takes a turn when Amir and Baba leave Afghanistan to go to Fremont, California. While they are there Amir finds a woman named Soraya who he quickly falls in love with. Their engagement and marriage are rushed because of Baba’s lung cancer. Shortly after they get married Baba passes away, and Soraya and Amir learn that they cannot have children. Rahim Khan then calls Amir and asks him to visit since he does not have much longer to live. Rahim Kahn knows about what happened to Hassan, he also knows that Amir knows, and that Amir needs to redeem himself so he sends him on a quest for fulfillment. He also tells Amir that Hassan was actually his brother. Rahim tells Amir that Hassan and his wife were killed a few years ago. Hassan’s son, Sohrab, was taken to an orphanage in Kabul.

Mental Health Nursing Practice Affiliationâ€Myassignmenthelp.Com

Question: Discuss About The Mental Health Nursing Practice Affiliation? Answer: Introduction Mental disorders are known to affect the brain Accounting and cause the unusual behavior of an individual towards the people around them. In case study two, Susan experiences a disorder that affects her way of interacting with people and how she manages her own life. She is diagnosed with a Bipolar disorder which affects her mood and energy in her day to day life. The paper seeks to find the main causes of this disease according to research and refer the same information in Susans case. It is also important to identify some of the nursing plans that a patient with this condition should receive from their medical personnels. There are also some ethical considerations that can be derived from the case study regarding the medical ways of dealing with the patients on their journey to discovery. A condition that affects the mental activity of an individual requires special medical care to help the patient over come or reduce its impact on their lives. Biopsychosocial Factors Bipolar disorder is a mental condition that causes sudden shifts in an individuals mood, energy and their way of conducting their daily activities. The disorder is said to affect certain parts of the brain and usually occurs due to malfunctioning of individual body cells(Consortium, 2009). In most cases, the condition is often triggered by genetic, environmental and personal factors. The following are the leading causes of Bipolar disorder: Genetic factors Bipolar disorder usually comes as a result of an individuals genes and family ties depending on the biological line they follow. Most cases of the disease occur to people whose a member of their family was once suffering from it or some form of depression. In the case of Susan, her brother had past cases of depression whereby he committed suicide after being diagnosed with Bipolar disorder. Such like an occurrence puts Susan and other family members at a 40-70% chance of getting the same mental condition. An experiment conducted in 2001, indicated that identical twins are at a significant risk if one of them has Bipolar and the other one might also be a victim(Kato, 2007). The stronger the genetic composition, the more likely it is for individuals to have a similar mental condition. If a parent is suffering from this condition, then their children stand a greater risk of getting the same as compared to their nephews or grandchildren. Another study of adopted twins shows that the chil d linked to the family bloodline can suffer a genetic disorder while the adopted one is untouched (Lichtenstein, 2009). All this research indicates that Bipolar disorder travels through ancestral roots and that is also represented by Susans case. Environmental and Personal Factors These are factors that individuals can control with the way they conduct themselves and also through relating to others. Most peoples lives follow a particular routine, and when it changes, they can end up stressed(Truog, 2008)). One of the issues that cause Bipolar disorder is depression and stress due to personal issues. An individuals brain function suddenly shifts and is overworked for some time which now might cause the malfunctioning of certain cells. Personal issues like loss of family members loss of a job, divorce or overworking might lead to excessive thinking which is in one way or the other the greatest contributor to mental problems(Bora, (2009). Changing of the daily routine is also a contributing factor as the brain is already used to taking commands in a particular manner. When one turns their sleeping, eating or working patterns, then they might be at a significant risk of suffering Bipolar disorder. Environmental changes are also stated to make a major impact on peoples minds especially those with mental issues or the elderly. As one is already used to staying in a particular house or external environment, when it changes then they get confused. The daily confusion is therefore associated with some modifications in their moods which in the long run might cause the Bipolar disorder. Neurochemical factors In the development of any mental or general body condition, there are objective factors which only medical professionals can understand, linked to the condition. For Bipolar disorder, there are some chemical reactions in the human brain which occur at given times, and their frequency develops the mental condition(Torres, 2007). The brain cells transmit chemicals, and when they malfunction, these chemicals might be dangerous to their mental health. Since it is a biological issue, it might lie dormant for some time and get triggered by external forces like stress and depression. These factors are hard to control, but people are advised as much as possible to avoid sudden changes that might affect them emotionally and mentally. Nursing Interventions Bipolar disorder is a long life condition that affects an individual but can be reduced and maintained through proper medical attention. Specified registered nurses and doctors are qualified to care for a patient with these disorders and help them maintain a normal life like the rest of the population. Although the condition might escalate at some point, these professionals responsibility is to reduce its impact through the right medication, counseling and physical activity or rest (Suppes, 2009) A nurse is expected to provide individual activities to the patient in such a structured manner to provide them with focus and security. A person is rather restless and wants to be so much involved in the activities around them when the condition is at the peak. There is, therefore, the need for an encouraged resting period which the RN can take a step to facilitate and help prevent exhaustion for the patient(Torres, 2007). The medical professionals and family members should also ensure that the victim takes lots of high-calorie drinks like milk and fruit shakes to increase hydration which is necessary for recovery. Bipolar patients experience a lot of anxiety and might seem derived from their environment(Arts, 2008). The best way to reduce this stress is to stimulate their surroundings by regulating the aspects of noise, light, and ventilation in the patients residence. In the cases of acute mania, the nurse is allowed to use seclusion and phenothiazines to reduce physical harm. Som e of the things that cause exhaustion and death include constant physical action, dehydration and lack of sleep, if they can be reduced, then the patients health improves. Their social lives should also be monitored to ensure that they can live comfortably in all the sectors (Pyle, 2007). Most victims become too generous and extravagant which leads them into spending a lot of money for no good reason. It is therefore good for the involved party to ensure that there is someone to control their finances and property. In Susans case, her sisters are in charge of her funds as she is insensitive of excessive spending. Some of them are violent, and as a medical professional, you should work to redirect that energy into other activities. Physical activity and exercise is a good strategy for redirecting an individuals energy as well as maintaining focus. Ethical implications Bipolar or any other type of mental disorder changes peoples behaviors and might make them vulnerable to mistakes and misjudgments. That is why there are ethical guidelines to ensure that the victims receive the best treatment to provide for their recovery and positive response. Ethics at work Some of the individuals who suffer Bipolar disorder are on a regular working basis under strict guidelines and procedures. The condition makes them change their energy towards their daily activities which might negatively affect their working conditions. In return, their employers and colleagues start to treat them negatively and discriminatively(Watson, 2007). They are worried that they might maketing mistakes in their duties and lead to organizations failure. A mental condition always puts an individual at a risk of diverting focus, and if working in a sensitive position, they might be a danger to their clients and the organization at large(Becker, (2010, February). ). If for example, an individual is an engineer, then Bipolar disorder makes them neglect their important roles leading to high losses. It is however good for victims to report their case to the Americans with Disabilities Act (ADA) as they protect workers with medical conditions(Vieta, 2008). It is ethical for people a round the patients environment to treat them positively to make them think in the same direction. If they are holding sensitive positions, then it would be happy to relieve them of those duties and assign simpler and less risky tasks. Treatment Preferences Treatment for any mental condition is structured in such a way that it benefits the patient. This is where the medical professionals come in and are expected to give the best services as per the law. It is important to understand that despite the mental situation of an individual, their consent is required to conduct any treatment. However a medical professional involved in psychiatric care should be in a position to determine the situation of the patient and ensure they are mentally stable (Goodwin, (2007)). Since Bipolar patients change moods and energies frequently, the doctor is expected to observe their clients and calm them down to obtain their consent when they are on their best behavior. Informed consent is also crucial in this case, and the doctor should be able to advise the victims and their families on the best way of approaching the situation and let them decide. It is only ethical that the doctor takes instructions from the patients or their families as the contrary mig ht get them into trouble in a court of law(Weisler, 2011) Issues with the law The factors of consent come down to the law and how to deal with cases connected to the treatment of the Bipolar disorder. If a certain procedure conducted with or without the consent of the affected parties result in an adverse impact, then complaints might arise(Smith, 2007). The law states clearly that the medical professional is responsible for the outcomes if they were things they could control in the first instance. It is therefore advised that the doctors and nurses take all necessary precautions before administering any medical treatment for mental disorders. Conclusion Bipolar disorder affects the mental as well as the physical being of an individual which states its severe impact on a person. The main causes are genetic roots, environmental and physical issues of a person as well as Neurochemical factors. A Proper nursing intervention like seclusions and medication are required to ensure that the patient keeps getting better by the day. There are also ethical implications that come with a Bipolar disorder like in the treatment, at work and the law which ought to be considered. Mental disorders are of high impact to an individuals life and should, therefore, be maintained to help the victim with healing. References Arts, B. J. (2008).

The hydrogen peroxide Essay Example

The hydrogen peroxide Paper The substances that I am going to use in this investigation are Manganese Dioxide and Hydrogen Peroxide. The Manganese Dioxide is a chemical catalyst and will be used to speed up the breaking down of Hydrogen Peroxide. I am using a chemical catalyst because it would give a more accurate result compared to organic or biological catalysts. This because organic and biological catalysts are enzymes, which require a certain temperature and will need to be kept constant as they work best between that temperatures. For example, 37 degrees centigrade to 40 degrees centigrade are temperatures when enzymes work best. This is because enzymes are found in the human body and are used for digestion. Also the human body has a body temperature of 37 degrees centigrade, which is why the enzymes work best at that temperature. Enzymes such amylase is found in the mouth breaks down starch in to maltose. In the stomach pepsin is used to break down protein in to polypeptides. In the small intestines using the enzyme peptidase produces amino acids when polypeptides are broken down. Also this is where the maltose is broken down into glucose using the enzyme called maltase. Hydrogen Peroxide with a chemical equation of H2O2 looks very similar to the equation for water H2O however having an extra Oxygen atom compared to water but this changes the properties of Hydrogen Peroxide. Hydrogen peroxide is a very reactive compound that can be used for a variety of reactions including bleaching and disinfecting minor wounds. Hydrogen peroxide H2O2 is made up of two hydrogen atoms and two oxygen atoms. We will write a custom essay sample on The hydrogen peroxide specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on The hydrogen peroxide specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on The hydrogen peroxide specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Hydrogen Peroxide H2O2 looks like water H2O, but that extra oxygen molecule makes this natural water additive one of the most powerful oxidizers. Hydrogen Peroxide H2O2 has many uses and is used to bleach textiles and paper products. Other industrial uses consist of Oil refining, Food processing, Landfills, etc. The Hydrogen Peroxide is constantly being broken down but at a slow rate. With the help of the catalyst, Manganese Dioxide this will speed up the decomposition of the Hydrogen Peroxide. Hydrogen peroxide typically decomposes to form water and oxygen at the rate of 10% per year. Here is the word equation for the reaction that I have just described: HYDROGEN PEROXIDE WATER + OXYGEN MANGANESE DIOXIDE Another way of describing this equation is in a balanced chemical equation: 2H2O 2H2O + O2 MnO2 Variables There are many things involved in this investigation, which could affect the speed the speed of this investigation. These called the variables. These variables consist of the surface area, the concentration, and the use of a catalyst, the amount of the catalyst and also the temperature. Heat, light, or a catalyst can accelerate the reaction. Surface area If the Manganese Dioxide has a large surface area increases the speed of the reaction because there will be more space covered by the Manganese Dioxide resulting in more of the Manganese Dioxide reacting with the Hydrogen peroxide hence increasing the speed of the reaction. And a smaller surface area will have a slower reaction rate compared to a larger surface area. Concentration of the Hydrogen Peroxide A high concentration of Hydrogen Peroxide would speed up the rate of decomposition. This because the concentration has an affect on how strong the Hydrogen Peroxide is. The higher the concentration the stronger the Hydrogen Peroxide is likely to be. So if the Hydrogen Peroxide has a stronger concentration that will mean that it is very reactive. Therefore being reactive means it will react faster and speed up the reaction.   The use of a catalyst There are two types of catalysts. They are biological catalysts and chemical catalysts. An example of a chemical catalyst is manganese Dioxide. A few examples of biological catalysts are carrots, potatoes and Liver. Catalysts are used to speed up reactions. Biological catalysts contain enzymes that break down certain substances in to other, easier to break down substances. The enzyme amylase, found in the saliva, breaks down starch into maltose. A disadvantage of using biological catalysts is that they rely on certain temperatures to ensure that they work best. Enzymes in your body work best at 37 degrees centigrade, which is your actual body temperature. When Manganese Dioxide is added to Hydrogen Peroxide, the Hydrogen Peroxide is begins to break down in to two substances. Hydrogen Peroxide breaks down in to Oxygen and water. To collect data I cannot measure the amount of water produced. This is because it will be very difficult to separate the water produced as it has been dissolved with the hydrogen peroxide. Instead I am going to measure the volume of Oxygen in centimetres cube, as the Oxygen bubbles will not easily dissolve in water. I am going to measure the oxygen by collecting the gas in a measuring cylinder, which is full of water. The theory is that when the gas goes in to the cylinder by a delivery tube, the oxygen gas pushes out the water. This process is called the downward displacement of water. I have chosen to investigate how the concentration of Hydrogen Peroxide affects its decomposition. Prediction I think that if I increased the concentration of the Hydrogen Peroxide the speed of the reaction will increase. I also think that as I increase the concentration of the Hydrogen Peroxide, more Oxygen will be produced. This will happen because the higher the concentration the more easy it is for the Manganese Dioxide to react with the Hydrogen Peroxide. This because the concentration has an affect on how strong the Hydrogen Peroxide is.

Population vs Populace

Population vs Populace Population vs Populace Population vs Populace By Maeve Maddox Lately I have begun to notice speakers and writers using the word populace where I would expect to see the word population. For example: With a young and skilled workforce – 65% of Turkey’s 74 million populace is under the age of 34 – producing 500,000 graduates a year, Turkey is now classified as a fast developing economy. Meanwhile, 3.7 percent of the 2012 populace – or roughly 23,436 people – held doctorates. Both words, population and populace, derive ultimately from a Latin word for people, but the words entered English with distinctive meanings. From the beginning, population referred to the collective inhabitants of a place, whereas populace had the meaning â€Å"ordinary people† as opposed to the titled, wealthy, or privileged classes. In Frances Hodgson Burnett’s The Little Princess (1905), the protagonist has been taught by her middleclass father to be kind to â€Å"the populace.† Thrust suddenly from a comfortable life into poverty, Sara learns what it is to be hungry. On the way to buy some buns, she notices a ragged little girl with â€Å"hungry eyes†: Sara knew they were hungry eyes the moment she saw them, and she felt a sudden sympathy. â€Å"This,† she said to herself, with a little sigh, â€Å"is one of the populace- and she is hungrier than I am.† Not only did the word populace refer to the less privileged part of the population, it was also used as a pejorative term for â€Å"the mob, the rabble, the unthinking masses.† Populace is increasingly used as a mere synonym for population, but its other connotations linger: The upper-middle class wants to lead an aroused populace against the true enemy, but the populace isn’t listening.- The American Interest, Vol. 6, No. 3, January 11, 2011.
