Application for Chemical Engineering at Princetone University

My life is all about problem solving: managing to live a difficult life in America after turning thirteen, finding â€Å"out of the box† to achieve my goals in debate, art, and HOSA, helping other teenagers with problems they struggle with... Designing a seemingly impossible pathway for me and others to succeed is my way of life, and a chemical engineer takes that to the next level. Everything around us -- from a bar of soup to a bucket of paint -- involves chemical engineering. The profession is not only about my favorite subjects, chemistry and math, but also about creating ideas, innovation, and new technology. This is what chemical engineers do, solving problems not just for one person, but for everyone. And being part of that amazing†¦show more content†¦I have also competed at many local academic competitions in chemistry, math and biology, placing 1st at the Chadron Scholastic Chemistry Contest, 1st (twice) at the 2011 and 2012 West River Mathematics Contest, and 3rd at the West River Biology Contest. Nevertheless, my current living situation offers me limited opportunities to explore the world of chemical engineering. Attending XXX University would mean the world to me -- giving me a chance to pursue my dreams with renowned professors such as XXX in an advanced laboratory and with people who share the same interests. At Princeton University, I can further explore the world of chemical engineering through Freshmen seminars, once again working with my peers. I am especially interested in the fall seminar Materials World at Mathey College, learning the technical processing and applications of materials around us. In addition, the spring seminar Emerging Micro and Nano-Engineered Technologies at Rockefeller College can also give me the opportunity to deepen my understanding of engineering. On top of everything, Princeton offers me amazing research opportunities I cannot find anywhere else. I intend to arrange summer employment at Princeton doing research with faculty members.

Racial Discrimination - 858 Words

Research topic: Does racial discrimination cause poverty among black people in America? The scene of ghettosThe with poor living conditions of the ghettos in whichwhere black people live is not uncommon., Iit actually manifests a larger picture of racial discrimination which is closely related to poverty. Racial discrimination is about the pre-conceived notion that black people are inferior; they are more prone to violence and totally relianty on social welfare to survive. As a result of these stereotypical images, black people receive low quality education and they will have less job opportunities, not to mention the limited access to the welfare system. In this essay, we shall discuss whether racial discrimination causes poverty among†¦show more content†¦This clearly illustrates how such kind of policpoliciesy aggravates existing disparities in the education system. Uneven distribution of wealth is also a major problem, causing poverty among black people. It is suggested that due to racial segregation and a controlled political environment by white people, black people usually find it difficult to assimilate themselves into the labor force and civil society (Ducan, 1999). In the U.S., per capita income of the whites is almost five times more than that of the blacks, which clearly illustrates the serious problem of a widening wealth gap between these twodifferent racial groups. The findings from Mean Racial Wealth Gap across 181 U.S. Metropolitan Statistical Areas shows that the standard deviation of wage between the blacks and the whites is the highest in among comparison toof different racial groups such as Latinos and white people and Asians and white people., Iit clearly points out that the most severe wealth gap exists between black and white people. However, upward mobility is restricted for the black blacks as they face racial discrimination in the process of hiring and firing. Only about half of working-age black men are employed, compared to two-thirds of white men, but even if black menpeople are employed, they are usually engaged in low-paid jobs so that they can barely affordsupport their daily expenses.

Nitric oxide therapy Free Essays

There is not much use for the lungs during the fetal life. At such stage, the function of the lungs is carried out by the placenta through the umbilical cord. Fetal life is characterized by a high pulmonary vascular resistance (PVR) with pulmonary blood flow being restricted to a less than 10% lung-directed cardiac output. We will write a custom essay sample on Nitric oxide therapy or any similar topic only for you Order Now Blood vessels that connect the heart and the lungs are constricted, sending the circulating blood back to the heart through the ductus arteriosus, a blood vessel that functions only in fetuses. In other words, the lungs in the fetal stage are bypassed. At birth, when the lungs finally assume the function of gas exchange, the PVR decreases, allowing for an increase in pulmonary blood flow. The blood vessel that is previously constricted, favoring blood flow to the ductus arteriosus is now relaxed, simultaneously with the permanent closure of the ductus arteriosus. This happens as the lungs become ventilated and the alveolar oxygen tension is increased. Persistent Pulmonary Hypertansion occurs when at birth, the lung circulation fails to achieve the normal drop in PVR, preventing the transition from fetal to newborn circulation. This failure results in the continuous functioning of the ductus arteriosus which impairs the flow of blood from the heart to the lungs and limits the amount of oxygen that can be picked up by the blood to be delivered to the different parts of the body. The blood that flows back to the heart remains in an unoxygenated state which could lead to the development of refractory hypoxemia, respiratory distress and acidosis. It is only in 1987 when nitric oxide (NO) was recognized as a key endothelial-derived vasodilator molecule. From then, research has been expanded to establish the role of NO throughout the body, and to discover its therapeutic potential.   To appreciate the effects of NO in alleviating pulmonary hypertension, it is important to gain understanding of its chemistry and mechanism of action. Nitric Oxide is a gaseous compound that rapidly diffuses across membranes and has a single unpaired electron. This explains its high reactivity, especially to Hemoglobin (Hb) in the blood. This nature of the compound accounts for its noted biological significance. It has been discovered to function as stimulant in the release of hormones; as neurotransmitter; a significant participant in the magnification of synaptic actions and learning processes; and an inhibitor in platelet aggregation, which makes it a marvel in the field of cardiology. In the field of pulmonology, nitric oxide is valued for its vasodilatory effect in the blood vessels. This effect can be explained by the mechanism involving the compound’s diffusion from the vascular endothelial cells to the subjacent smooth muscles of the pulmonary vessels. From here, NO activates the enzyme guanylate cyclase to change conformation to promote smooth muscle relaxation by converting GTP to cGMP.   This vasodilatory effect signals the mechanism to modulate blood flow and vascular tone. Given the mechanism of action, it is easy to surmise how NO can be utilized as a therapeutic agent in the management of blood-vessel-related diseases such as those related to the heart (hypertension), the reproductive system(erectile dysfunction) and in this case, the lungs (Persistent Pulmonary Hypertension in infants (PPHN)). Before NO, treatments used in infant PPHN are hyperventilation, continuous infusion of alkali, tube vasodilation and vasodilator drugs. A study on the effects of these various treatments was done by Ellington, Jr., et. al., (2001) showing no specific therapy clearly associated with the reduction in mortality in infants. In determining whether therapies were equivalent, the study showed that hyperventilation reduced the risk of extracorporeal membrane oxygenation (ECMO) with no oxygen increase at 28 days, while alkali infusion increased the use of ECMO as well as an increase in the use of oxygen at 28 days (Ellington, Jr., et. al., 2001). ECMO is a highly invasive procedure that requires major surgery, performed in serious cases of PPHN when patients fail to respond to treatments. It is only after post-lab studies were able to identify the role of NO-cGMP signaling in the regulation of lung circulation that NO therapy was developed for PPHN (Channick, R., et. al., 1994). Like previous treatment methods, NO therapy improves oxygenation as well as reduces the risk of ECMO in infants with PPHN (Oliveira, et. al., 2000). But because nitric oxide is capable of acting on its own upon inhalation to relax the blood vessels and improve circulation, it is considered as a less invasive procedure in the management of infants with PPHN compared to the previous treatments mentioned in the preceding paragraphs. The efficiency of the treatment procedure can be determined by observing its effect on the patient’s ventilation and blood flow, which is a determinant of the efficiency of transpulmonary oxygenation and partial pressure of oxygen in the systemic arterial blood (Ichinose, et. al., 2004). NO therapy enhances the mechanism by which blood flow is redistributed toward regions in the lungs with better ventilation and higher intra-alveolar partial pressure of oxygen (Ichinose, et. al., 2004). Other treatments used in the management of PPHN such as tube ventilation, alkalosis and intravenous vasodilators were shown to be effective in ameliorating pulmonary hypertension in some infants, but in many instances, it does not, as ECMO almost always becomes a necessity in saving the life of the infants (Ichinose, et. al., 2004). A type of hyperventilation has been proven not to increase the risk of ECMO, but unlike NO-therapy (Ellington, Jr., et. al., 2001), it is invasive as to require a tube inserted inside the infant’s trachea. In patients with moderate PPHN, there is an improvement in arterial p a O 2, reduced necessity of ventilator support and low risk of progression to severe PPHN (Sadiq, et. al., 2003) and this, without the risk of increasing the incidence of adverse outcomes when the age of 1 year is reached (Clark, et. al. 2003). Inhaled NO is able to rapidly increase the arterial oxygen tension and increase the blood flow in the lungs without causing systemic hypotension (Roberts, 1992; Kinsella, 1992). No apparent increase in morbidity has been shown after one year of treatment with NO (Aparna and Hoskote, 2008). For high-risk infants with PPHN, inhaled NO has been found to lessen the risk of pulmonary hypertensive crisis (PHTC) after congenital heart surgery (Miller, et. al. 2000). Studies on the role of NO in the management of PPHM show that while it is therapeutic, it also prevents the occurrence of chronic lung disease which affects morbidity. Vascular cell proliferation and pulmonary vascular disease have been shown to decrease with NO in the newborn (Roberts, et. al., 1995). In addition, while NO treatment can be more costly, it is the most cost-effective among other methods because of the reduced need for ECMO (Angus, et. al. 2003). For these reasons, it is understandable why NO therapy seems to have taken over in the area of PPHN treatment. References Angus DC, Clermont G, Watson RS, et al. (2003).

Lucid Dreams and PTSD Essay Example For Students

Lucid Dreams and PTSD Essay The Stigma Surrounding Lucid Dream Therapy In PTSD In our society, dreams are often thought of as meaningless biology (LaBerge 1). The stigma that has accompanied dreams into our century can be thought of as quite unfortunate. This stigma accompanies all types of dreams, including lucid dreams, the conscious awareness in a dream. In the small body of research that indicates the possible therapeutic uses of lucid dreaming, one can see how hard it would be for society to accept this kind of therapy if viewing the key element, dreaming, as meaningless biology (LaBerge 1). Society needs to change the attitudes around dreaming due to the possible benefits that dream therapy could have on problems such as Post-Traumatic Stress Disorder (PTSD). The benefits that lucid dream therapy could have for these treatments show why society needs to embrace all types of dreaming as important and useful human resources. As defined by Stephen LaBerge, Lucidity, allowing as it does flexibility and creative response, presents a means of resolving dream conflicts and hence fosters a return to effective self-regulation. This is the basis of approach to healing through lucid dreaming: to facilitate the persons self-healing mechanisms by means of intentional imagery on the mental level (Healing through Lucid Dreaming 1). Those who have had a lucid dream but are unfamiliar with the terminology could easily recognize their dream as lucid. Almost all dream researchers agree to these two basic principles of lucid dreams and lucid dreamers: a) that lucid dreamers will frequently awaken from REM sleep once dream consciousness is achieved and b) that lucidity will be easiest to induce at times in the night when the body is likely to be changing from REM to waking. This makes lucid dreaming sound quite disruptive to sleep. It is perhaps a relief that lucid dreaming is normally rare unless one has trained him/herself for lucidity. Proposing that lucid dreaming has a connection to the treatment of PTSD, an outline is needed. Appendix A and B outline various aspects of PTSD. The first is taken from Warning Signs of Trauma Related Stress (taken from Tanenbaum, DeWolfe and Albano) and the other from DSM-III-R (PTSD 1). There is mention of nightmares being a symptom of PTSD. This obviously means that dreams of the trauma and that these dreams are of a disturbing nature. LaBerge defines nightmare as the result of unhealthy reactions (Healing Through Lucid Dreaming 1). Even though disturbing dreams are said to be a symptom of PTSD, the treatment is non-dream oriented. This is logical because physical problems can be treated in non-physical ways and vice-versa. What is illogical is that dream oriented treatment is not considered. This could be simply an oversight, but could also be an indicator of the aforementioned stigma surrounding dreams. Dream therapy is not a new phenomenon, but it seems unfortunate that it is popular only within select circles or therapists. Lucid dreams could be an important tool for the recovery of PTSD victims and it is unfortunate that this stigma could be the preventing factor surrounding this type of therapy. In an article by George Howe Colt, he discusses the advantages of lucid dreams: Instead of being eaten by a dream monster, lucid dreamers may be able to eat the monster themselves. Instead of showing up for an important exam dressed only in his underwear, a lucid dreamer can race home and put on clothes or, knowing its only a dream, throw caution to the winds and find out what happens when he walks into an exam undressed. The value of lucid dreams is you can have any imaginable experience without consequences, says LaBerge, himself a lucid dreamer (Life Special/Cover 5). The first of these advantages, the dream monster, involves being less afraid of the threatening situation (Colt 5). If a person suffering from PTSD has a distressing dream about their trauma, it could be very beneficial to re-experience the trauma while having more control and less fear. .u82d7cd79fa8ef5d1838b10d40e8d05ee , .u82d7cd79fa8ef5d1838b10d40e8d05ee .postImageUrl , .u82d7cd79fa8ef5d1838b10d40e8d05ee .centered-text-area { min-height: 80px; position: relative; } .u82d7cd79fa8ef5d1838b10d40e8d05ee , .u82d7cd79fa8ef5d1838b10d40e8d05ee:hover , .u82d7cd79fa8ef5d1838b10d40e8d05ee:visited , .u82d7cd79fa8ef5d1838b10d40e8d05ee:active { border:0!important; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .clearfix:after { content: ""; display: table; clear: both; } .u82d7cd79fa8ef5d1838b10d40e8d05ee { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u82d7cd79fa8ef5d1838b10d40e8d05ee:active , .u82d7cd79fa8ef5d1838b10d40e8d05ee:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .centered-text-area { width: 100%; position: relative ; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u82d7cd79fa8ef5d1838b10d40e8d05ee:hover .ctaButton { background-color: #34495E!important; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u82d7cd79fa8ef5d1838b10d40e8d05ee .u82d7cd79fa8ef5d1838b10d40e8d05ee-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u82d7cd79fa8ef5d1838b10d40e8d05ee:after { content: ""; display: block; clear: both; } READ: Synthesis - Preserving Artifacts Essay This gives the opportunity for exploration of other possible outcomes (as seen in attending the exam to view the reactions while only half dressed) or the exploration of feelings in general.
