Elizabeth Bennet Essay Example | Topics and Well Written Essays - 500 words

Elizabeth Bennet - Essay Example (87) Elizabeth is intelligent, and has a quick and lively wit. This in particular distinguishes her from Lydia and Mrs Bennet, because Pride and Prejudice makes heavy use of dialog to characterize people and tell the story. Elizabeth thinks and speaks on a variety of subjects, whereas Lydia and Mrs Bennet are concerned only with parties, officers, and husbands. Elizabeth is sometimes deeply embarrassed by the behavior of her family, and recognizes that Lydia's behavior is out of control in part due to lack of discipline on her mother's part: "supported by [her] mother's indulgence, what chance could there be of improvement" (175) Both Elizabeth and Lydia are vivacious and lively, but while Elizabeth tempers these qualities with good manners and her understanding of and attention to social conventions, Lydia lacks any sort of good judgment. She is unable and unwilling to restrain her impulsive nature, and is never able to understand that her behavior reflects badly on herself and her family. Returning to Longbourne after marrying Wickham, Lydia is unrepentant, full of "ease and good spirits" (255) and thinks only of boasting about her marriage, and other "subjects which her sisters would not have alluded to for the world". (255) Elizabeth shares few, if any qualities with her mother

Dams, hydroelectricity, and the effect apon the ecosystems Term Paper

Dams, hydroelectricity, and the effect apon the ecosystems - Term Paper Example However, the idea of constructing more dams in various places has been welcomed with great opposition. Many economic and social arguments have been raised against the construction of dam, but the most profound fact that has overshadowed all other arguments is the major ecological effects that large dams have on the ecosystem. Considering hydroelectricity, hydropower is actually a renewable energy since it depends on the water cycle on earth for the generation of electricity. The cycle of water begins when the water evaporates to form clouds which in turn condenses and precipitates back to the earth and gets back to the water reservoirs. Despite the fact that hydropower pose no effects on the quality of air, the process of constructing and operating large hydropower dams can have significant impact on natural ecosystem such as river systems wildlife and aquatic life population. The assessment of how hydropower affects the environment can be effectively done by reviewing different case s. This paper aims at discussing the effects that hydroelectricity and dams have upon the ecosystem. Effects of Dams upon the Ecosystem Dams have significant effects on both the downstream and upstream ecosystems. Dams comprise hindrances on rivers longitudinal exchange and they alter numerous processes in the natural environment. Flooding of dams in the upstream brings about total damage to the terrestrial ecosystems via a process known as inundation. Flooding eliminates all terrestrial animals and plants inhabiting the affected areas. Water reservoirs inhibit some aquatic species from migrating by obstructing their pathways1. On the downstream, there are obvious changes in sediment transport, water quality and temperature, and flow regime. These particular changes occur gradually and they are not easy to predict. The very common effect of large dams downstream is the reduction of annual water discharge; this lead to an increase in low flows and a decrease in high flows. Flood peak s reduction decreases the period, degree and frequency of floodplain outpouring. A decrease in the channel-formation shrinks the chances of channel migration. Transportation of sediment in the reservoir brings about complex alterations in aggregation and deprivation on the dams surface. Regulation alters the chronological flooding prototype, an effect that desynchronizes temperature systems and yearly water flow. These particular alterations have a direct influence on some dynamic factors affecting the heterogeneity of habitats and the integrity of the river ecosystem ecology. Changes in water quality, water to land interface, and thermal regime have direct impact in primary production, which translates to long term effects on aquatic life and other members in the upper food chain. Dams may also bring about alterations in the ecosystem even at a distance far from the dam2. For instance, any alteration on the transportation of sediments may result in changes in floodplains, coastal d elta and river morphology numerous of miles from the dam site. The river ecosystem responds to dams in several, complex, and diverse ways. Subsequently, while endeavouring to establish the impacts of dams on the ecosystem there is need for large bank of information relating to: riparian vegetation and related fauna; quality of water; rivers hydraulic features; geomorphologic features; aquatic animals and their environment; importance of river’

Pursuing Criminal Syndicates Essay Example | Topics and Well Written Essays - 500 words

Pursuing Criminal Syndicates - Essay Example In case of a terror attack, the doctors’ lack of bioterrorism knowledge would cause worse situation (Frist, 2009). The other significant concern is the inability of the government to deliver medicines in case of a bioterrorism attack. This situation is worrying since the citizens would lack quick response from the government, to deal with an occurrence of bioterrorism. There is a lack of adequate response techniques and strategies because of the rapid spread of such outbreaks such as smallpox. The outbreak is also air-borne and has a potential for unimaginable large numbers of fatalities (Frist, 2009). The police plays a significant role in responding in resolving to event of bioterrorism. Firstly, they help controlling movement out and in the contaminated areas. This aims at stopping the spread of contamination (Frist, 2009). In conjunction with the medical personnel, they play a part in determining the extent of exposure. Secondly, they are critical in bringing in resources needed to characterize the contaminated areas in preparation for remediation. This includes feeding the workers, storage of supply and equipment as well as laboratory facilities (Frist, 2009). Thirdly, the police plays even a bigger role participating in investigating the attacks. This tries to find out the culprits and understand their motives. This also helps to prevent further attacks from the terrorists by when they arrest them (Frist, 2009). This entails a society, which resolves to violence or criminal activities for selfish benefits. There are various forms or categories of organized crimes. Firstly, there are providers of services termed illegal by law. This includes such activities as gambling, prostitution, and protection (Albanese, 2010). Secondly, there are individual in the supply of prohibited goods, comprising of drugs and pornography. Another form includes the money laundering

Why is the trafficking of naive lymphocytes important Outline the Essay

Why is the trafficking of naive lymphocytes important Outline the stages in the development of the specific immune respons - Essay Example Our bodies are both fragile and resilient at the same time; being so soft and easily broken, yet keeping us alive even during the worst of conditions, always adapting and always surviving. One of the important factors that keep us alive is our immune system and its ability to adapt to the environment and the pathogens it contains. According to Gene Mayer, PhD, there are two ways wherein the body can protect itself from infection: Innate or nonspecific immune system, and Adaptive or specific immune system. ‘The innate immune system is the first line of defense’ which provides immediate, but nonspecific responses to infection (e.g. skin, mucus, tears, sneezing, etc.). The adaptive immune system is slower and responds only to specific antigens with cells called lymphocytes. Once the adaptive immune system responds to a specific antigen, the body will remember it and will produce antibodies to combat the antigen more effectively every time it comes back.1 There are two main types of lymphocytes involved in adaptive immunity--B lymphocytes (B cells) and T lymphocytes (T cells). These cells are produced in the bone marrow. One of the differences between the two is that the T cells have to migrate to the thymus gland to mature. Stein and Nombela-Arrieta (2005, pp.1-12) state that these lymphocytes that have just matured and have yet to encounter an antigen, are called naive lymphocytes. From the bone marrow and the thymus, the lymphocytes are then trafficked through the bloodstream to the secondary lymphoid organs (SLO), which are the peripheral and mesenteric lymph nodes, spleen and gut-associated lymphoid tissues called the Peyer's patches. In the SLO, once the naive cells encounter antigens and become activated, they will undergo changes and will eventually leave to combat the infection.2 Kuby wrote that when a pathogen enters the body, it enters the bloodstream and is transported to the lymph nodes and lymphatic organs where antigen presenting cells ( APCs) break it down into antigen compounds to be bound to Major Histocompatibility Complex (MHC) molecules. The naive helper T cells become activated once they encounter the antigen bound to the MHC molecules. It then becomes an effector cell (Th) that produces cytokines which activate B cells, T cells, macrophages and other cells included in the specific immune response. Once the Th cells are released into the bloodstream, when they find the antigen, they secrete their cytokines. T cytotoxic cells (Tc) become another effector cell called the cytotoxic T lymphocyte (CTL). This kind of effector cell does not produce cytokines but is designed to destroy infected cells. Once the B cells encounter the antigen, they proliferate and differentiate into antibody-secreting plasma cells whose antibodies attach to the antigen, effectively neutralizing it. Other B cells turn into memory B cells that allow for a faster response to illness once the same pathogen enters the body again.3 Mayer and Nyland (2010) pointed out that ‘since there are relatively few T or B lymphocytes with a receptor for any particular antigen (1/10,000 – 1/100,000), the chances for a successful encounter between an antigen and the appropriate lymphocyte are slim.’4 The chances of encountering the right antigen with the right antibody are maximized with recirculation to the SLOs. The lymphocytes constantly circulate from the lymph organs to the blood via lymphatics if there is no antigen present. ‘It is estimated that 1-2% of lymphocytes recirculate every hour’ (Mayer & Nyland, 2010).5 If it does encounter an antigen, the cells differentiate into the effector cells (B, Th, or Tc) to combat the infection. After the infection, it can go back to the blood stream

Molecular Fluorescence Analysis of Proteins Lab Report

Molecular Fluorescence Analysis of Proteins - Lab Report Example As the electron returns from the lowest triplet state to the singlet ground state, a photon is released. The high sensitivity and specificity of fluorescence techniques facilitates the study of individual protein molecules. Therefore, this experiment sought to determine the source of fluorescence in serum albumin by first establishing the fluorescence of two key amino acids that make up serum albumin. Such a study would enable a detailed study of serum albumin as a protein. The experiment also aimed at establishing the concentration of riboflavin using the absorption of known concentrations of riboflavin. Solutions of 10 Â µM tyrosine and tryptophan were made to volumes of 100Â µL each by first preparing 100 mL of 1mM solutions and diluting them to 10 Â µM. The applications software of the fluorescent instrument was loaded after which the condition parameters were set. An emission scan range of between 290 and 380 nm was set alongside slits of 5nm. The emission wavelength was set to 280 nm, and the emission tab was clicked to obtain the emission spectrum of the buffer solution. The spectrum was saved after which the same procedure was repeated for tryptophan. Thereafter, an excitation spectrum for tryptophan was prepared by choosing the optimal emission wavelength according to the results of the emission spectrum. A tyrosine spectrum was obtained using similar conditions as those of the buffer. The tyrosine band was then obtained by subtracting the buffer spectrum from the tyrosine spectrum. All these steps were repeated for serum albumin making sure to save all the spectra. 1.0 mL of 10 ppm riboflavin solution was measured into a 100 mL volumetric flask and diluted using the buffer to make a 100 ppb stock solution. Standard solutions were then prepared using clean volumetric pipettes rinsed with HPLC water. The final concentrations of the standard solutions were

Global Warming Essay Example | Topics and Well Written Essays - 750 words - 2

Global Warming - Essay Example Each of these shareholders has something to gain or to lose based upon their own interpretation and as such this topic has been a particularly messy one to understand and to define. Accordingly, this brief essay will attempt to briefly analyze this monolithic problem through the lens of one particular article that promotes the understanding that global warming is in fact something of a hoax. The article, entitled â€Å"The Global Warming Conundrum† discusses the fact that something of a a middle path to this ongoing debate that has been raging and consuming valuable time in the process should be engaged. Furthermore, this author will seek to make a determination with regards to the question of whether human action or natural causes best explains the climate fluctuations that planet earth has recently been chronicling. Lastly, as a function of the previous points of discussion and analysis, the author will attempt to proscribe a reasonable and performable set of steps and solut ions which both the scientific community and the world at large could and should seek to employ as a function of ameliorating the stress on planet earth and the issues at hand. Furthermore, as a means of bringing such an understanding about, the analysis will also rely upon relevant scientific publications on the topic as well as verifiable statistics and charts concerning overall levels of climate change and corresponding increases in CO2 emissions by humans over the past several decades. However, noting the global climate change is an issue is not, in and of itself sufficient. As such, the analysis will also consider the rapidly increasing demand that fossil fuels have been projected to assume over the next several decades and posit a potential alternative to further environmental degradation (Fowler 43). Firstly, the author of the article presents contrary point of view that strongly believes that the swings in climate change are the direct result of the presence of high amounts of human CO2 in the atmosphere that is causing a greenhouse effect on the planet and thereby causing world temperatures to rise. Prima fascia of this argument is the belief that human CO2 emissions are responsible for the changes to the global climate. It follows therefore that those which ascribe to this point of view are the most vehement that drastic and immediate changes to the manner in which human beings interact with planet earth and seek to use her resources in order to achieve a high standard of living be re-assessed as a function of whether such practices are best for the future health and longevity of the planet. However, the biggest drawback to this particular line of reasoning is the fact that the overall extent to which human CO2 factors into the percentage of total CO2 generated by planet earth on a yearly basis is so miniscule as to be laughable. Indeed, numerous studies have convincingly noted that human CO2 emissions only account for around 4% of total earth CO2 re lease in any given calendar year. Although this by no means relieves humans of their responsibility towards the planet, it does however help put into perspective the precise scope of this problem and the means by which it should be sought to be rectified. The problem with this point of view, as the article indicates, is of course the fact that the main causal factors for global climate change with respect to the recent changes in temperature patterns have not been considered. For instance, there is a preponderance of evidence that the size and heat the sun generates is of course non-uniform and varies depending on the level of solar flares and solar storm activity. As such, scientists have noted that beyond CO2
