Assessment 2 (6 assignment into 1) - Essay Example The formula for computing surface area of pyramids shall be provided, with the teacher demonstrating how to substitute values in the formula. The students will be given exercises to practice computing for surface area of pyramids which will be checked as a class at the end of the lesson. the concept of solid shapes and their surface areas. They should be aware that there are formulae to be followed in computing for the surface areas of various shapes and know how to substitute values and finding missing values using the formula. The Lateral Area is surprisingly simple. Just multiply the perimeter by the side length and divide by 2. This is because the sides are always triangles and the triangle formula is base times height divided by 2 Using the formula: 1/2 Ãâ€" Perimeter Ãâ€" [Side Length] + [Base Area]. The teacher illustrates to the class how to use the formula and substitute the necessary values on the blackboard, then does a few exercises with some students she may call on. Later on, students are grouped according to their abilities, given various number problems to solve for the surface areas of various pyramids. Kozioff, et al (2000) contends that the teacher can more easily monitor the progress of the students when they work in smaller groups with more or less the same guidance needs. Killen (2003) emphasized the need to practice students’ newfound skills and in this particular case, it is the computation of the surface area of a pyramid following a prescribed formula. At the end of the session, everyone comes together to compare their answers. It will be necessary to call on students to demonstrate on the blackboard how they came up with their answers to check if they followed the correct proced ure in using the formula. Should there be errors, the teacher throws the question to the class as to where it went wrong, but if students cannot figure it out, then she shows

Art in the Age of Revolution - Essay Example lieving in this idea, the Realists recorded in often resolute aspects of the current day survival of modest people that paralleled with the associated movements in the naturalist literature of Emile Zola, Honore de Balzac, and Gustave Flaubert. The assessment of the working class into the area of high art and literature overlapped with the socialist philosophies of Pierre Proudhon and Karl Marx’s Communist Manifesto, which were published in the year 1848 and led to an urge of manual revolution (Nineteenth-Century French Realism, 2012). Gustave Courbet was a great French painter and he developed the term Realism in art to sum up a fashion of painting that emerged in France after the 1848 Revolution. The painters and sculptors who followed Realism wanted to express neither magnificence nor attractiveness. Rather it was all ordinariness that they were focused into. Artists of the time completely surveyed the limits of this artistic concept. Popular artists like Auguste Rodin succ eeded in initiating this heroicism in their works. The mid nineteenth century school of French Realism was an introduction for numerous other movements of the modern art related to Realism that appeared later in the twentieth century. Social Realism was also included in these movements (Artists of the Realism School (c. 1840-1900), n.d.). Socialist Realism in Modern Art: In the field of modern art, the concept of Social Realism is conventionally linked with interwar American art. It provided remarks on social, economic, and political conditions that existed during an era of Depression. There were two movements of modern art that could be associated with a left-wing character. These were the American Social Realism and Soviet-inspired Socialist Realism. There had been significant events that... From the above study, it can be very well concluded that during the mid nineteenth century, French artists had significantly given rise to the revolution involving Realism in their art and avoided Romanticism. The main purpose of this plan was to bring out the lives of the common people of their times in the representations and portrayals of the arts and paintings as well as literature. This can be considered to have an association with the social aspect of lives as well since the depictions would communicate some message or the other in regard to the human lives and their society. This author talks that Realism is a form of presenting the work of art in which different issues are portrayed in as simple a way as feasible, exclusive of romanticizing them and without any rules of formal artistic theory being followed. This paper makes a conclusion that the label of Socialist was not much obtained in the movement and Realism was considered more suitable to the movement and the acts of the artists as represented through their works. Thus, as far as the movement is concerned it can be said that the French Art in the mid nineteenth century had taken significant measures towards their society trying to focus and represent their conditions through their paintings and creations but the label of socialist might not been involved or attached to realism to great extents in this regard, although their works did have socialist message for the world.

Politic papers - Essay Example Wars have raged in these regions for several years and the devastation brought about these wars has been tremendous. To be specific, the Iraq War had cost so much destruction of lives and properties. For the next five years, the destruction of lives and properties will most likely continue. On the other hand, the aftermath of the war could take a great toll on the economy and stability of the area for the next 20 years. The implications of the war in Iraq on the lives of the people and the security of the area are so great that the United States should address this problem more fully. I fully understand the position of the United States on the issue of terrorism but the point is that there are other ways of address terrorism other than counter-violence. We all know that violence begets violence and if the United States does not take concrete moves to end the violence in the area once and for all, this situation will not be resolved in the next several years. I believe that a solution of the problem would be a shift in foreign policies in Iraq. Instead of focusing on counter-terrorism and supporting the armed conflict in the area, the United States government should focus its attention more on the rehabilitation and rebuilding of Iraq through education, economic development and political participation by the people. We must understand that as long as the people in the area feel oppressed and deprived, they will be more prone to violence. Due to the presence of oil in this region, most of us are lead to believe that the economy in these parts of world is doing well. Unfortunately, that is not the case. Although some of the oil rich countries in these areas are dong really well, many of them are struggling to against poverty and deprivation. According to the report of the World Bank in 2006, about one in every five persons in the Middle East and North Africa Region can be

World Hunger Essay Example for Free

World Hunger Essay Hunger and starvation is an issue that plagues countries all over the world, regardless of how developed that country may be. From the United States to villages in Uganda, there are people who go days without eating, resulting in malnutrition and even death. Many charities and programs such as the United Nations World Food Program are currently working to save lives, but there are still millions of people in need of help and assistance. The UN World Food Program addresses hunger everywhere, including countries that are typically not associated with starvation. In Kabul, Afghanistan not all families can always afford enough food on a daily basis to feed their children. With the region being labeled more as a war-torn area, people often overlook the economic impact of political situations and how the natives are affected. Many adults have to work a minimum of ten to twelve hours every single day of the year, just so they can provide for their families; and if such work is not available, there is no guarantee that they will eat. Africa, in particular, is renowned for its third-world status and the widespread hunger that the entire continent has faced for years. Not only do poverty and a lack of resources add to the high levels of starvation, but the HIV/AIDS epidemic has also contributed to the problem. In Zambia, for example, the UN works with several mothers who are HIV-positive, yet they have several children that they need to raise. In the entire country, 14 percent of the people now have HIV and 16 percent of the entire female population is infected. Many of these women are also working mothers who struggle to find the energy to work long hours due to their illness. They also tend to forgo eating so that their children will have more food each day—a cycle that leads to further deterioration of their own health and increasing weakness, so they are unable to keep up with their work schedules. Fortunately for some of these families, the UN has intervened by providing nutritious food and medicine to treat some of the HIV symptoms. This has enabled many mothers—the UN’s target population in Zambia—to continue working while also building back up their own physical strength. Another example of the UN’s work is Congo, where malnutrition has recently been a rising concern. UN workers have been effective in teaching the natives of Congo to farm and plant their own food, as well as the importance of a nutritious diet. One of the countries most closely associated with hunger and starvation, of course, is Haiti. The UN World Food Program has had an increasing population on the island ever since the major earthquake back in January of this year. Working together to rebuild the country, the UN has made deals with many of the survivors—they provide the people with cash and food rations periodically in exchange for labor, which includes clearing the debris, paving roads, and reconstructing houses and other important buildings. Not only has the World Food Program helped with Haiti’s hunger issues, but they have essentially provided earthquake survivors with a sort of job market. Without the program, the country would clearly have no standing economy, and therefore there would be no available work. Since the labor that the people provide in exchange for food and money all goes towards reconstructing their own country, this process implemented by the UN completely benefits Haiti and its people, especially in the long-run. Perhaps the greatest feature of the United Nations World Food Program is that it addresses hunger from all sides. They do not simply enter a country, distribute food, and then leave. Instead, they work closely with the people there and provide them with the proper skills and knowledge so that they are able to feed themselves and their families forever—not just when the UN is there. Still, due to the fact that there are far more starving people than there are those who can help them, a great portion of the world still needs assistance and there is an enormous amount of work that has yet to be done.

Frequency Response of Electrode Materials in EIS Measurement

Frequency Response of Electrode Materials in EIS Measurement Furthermore, complementary information about the frequency response of electrode materials is provided by EIS measurements and one can estimate the capacitance changes with the operating frequency.64-65 It is well know that the complex form of capacitance is dependent on frequency, which is defined as follow:66-67 (6) where C(ω) is the real part of the complex capacitance and C(ω) is the imaginary part of the complex capacitance C(ω) and they are expressed as formulas (7) and (8):66-67 (7) (8) where Z(ω) and Z(ω) are the respective real and imaginary part of the complex impedance Z(ω). ω is the angular frequency and it is given by ω =2Ï€f. At low frequency, C(ω) corresponds to the capacitance of the electrode material and C(ω) is ascribed to the energy dissipation by an irreversible process that leads to a hysteresis.66-67 Fig. 15 shows the real and imaginary part capacitance as a function of frequency for Li-POAP/ERG/GC, POAP/ERG/GC and ERG/GC electrodes. It can be clearly observed that C(ω) gradually decrease with the increase of scan rates for each electrode as shown in Fig. 12F, however, the Li-POAP/ERG/GC electrode exhibits slow deterioration of capacitance due to fast ion diffusion and transport (Fig. 15A). In addition, the C(ω) of the Li-POAP/ERG/GC electrode approaches saturation at a frequency below ~ 0.01 Hz whereas the C(ω) of POAP/ERG/GC electrode does not show any sign of saturation as low as 0.01 Hz, indicating slow diffusion of electrolyte ions (Figs. 15A and B). Importantly, the relaxation time constant (Ï„0), which is also known as the dielectric relaxation time of the supercapacitor,66, 68 is a figure of merit of a supercapacitor. This parameter represents one of its discharge characteristics. It has been studied for each electrode based on the analysis of complex capacitance. The relaxation time constant, Ï„0 (=1/2Ï€f0) can be calculated from the plots of C(ω) and C(ω) vs. frequency. From the frequency corresponding to the half of the maximum value of C(ω), the relaxation time constant (Ï„0) can be determined. The change in the imaginary part of the complex capacitance C(ω) with frequency goes through a maximum at a frequency, f0, from which the value of Ï„0 can be calculated. From Figs. 15A and B, it can be noted that the Li-POAP/ERG/GC electrode shows a clear peak formation while the POAP/ERG/GC electrode has not reached the maximum even at the lowest frequ ency used in this study. The f0 value of Li-POAP/ERG nanocomposite is 3.98Ãâ€"10-2 Hz, corresponding to the characteristic relaxation time constant Ï„0 = 3998 ms, which is much lower than that of POAP/ERG nanocomposite, revealing fast accessibility of the electrolyte ions for the former nanocomposite. The smaller Ï„0 of the nanocomposite correlates with the better capacitance retention at high scan rates in the CV measurements. Therefore, lithium intercalated POAP/ERG nanocomposite is a potential promising electrode material for delivering high power and energy. In addition, investigation of the complex capacitance form of the ERG/GC electrode reveals that the C'(ω) of this electrode approaches saturation at a frequency below 15.8 Hz, which means that equilibrium ion adsorption can be achieved in 63.3 ms, suggesting most of the electrolyte ions reach the adsorption sites (Fig. 15C). In comparison to Li-POAP/ERG/GC electrode, the smaller value of relaxation time constant ( Ï„0 = 2.5 ms) correlates with very ultra-fast accessibility of the electrolyte ions for the ERG/GC electrode and the better capacitance retention at high scan rates in the CV measurements which is in good agreement with results obtained from cyclic voltammetric measurements (Fig. 12F, green line). In order to investigate the effects of different types of anions on the specific capacitance of POAP/ERG nanocomposite, the modification of the ERG/GC electrodes has been carried out in different acidic solutions containing HNO3, HClO4 and HCl and corresponding lithium salts as supporting electrolyte and subsequently, have been evaluated in the corresponding monomer free solutions. The cyclic voltammograms of the modified electrodes in presence of different anions are shown in Fig. 16A. Qualitative analysis of total charges associated with the voltammograms recorded in the presence of different anions reveals that the specific capacitance for anions decreases in the direction of K+. In addition, the values of specific capacitance derived from the cyclic voltammetric (Fig. 16D) and impedance spectroscopic measurements (Figs. 16E and F) do indeed coincide as tabulated in Table 3. Although one can expect the smaller size of Li+ ion to provide facile insertion/expulsion to/from the elec troactive film, the greater specific capacitance has been obtained in the presence of Na+. As for studied anions, it has been noted that the trends in direction of ionic mobility and ionic radius are going the same way.69-70 Possessing the greatest mobility and the smallest radius have led to estimation of the greater specific capacitance would be obtained as a consequence of more being intercalated into the POAP/ERG nanocomposite, which is in good agreement with experimental results. On the contrary, the trends in ionic mobility 69 and ionic radius 71 contrast with those in hydration enthalpy 70 and hydration number 71 for the studied cations. These inconsistencies have hindered prediction of which cation would be incorporated into the POAP/ERG nanocomposite easily. The obtained specific capacitance values (Table 3) decrease in the order of Na+ > Li+ > K+ which confirms the facile incorporation of Na+ into the POAP/ERG is more than likely. Along the lines of evaluating of effects of different types of cations and anions on the POAP/ERG nanocomposite, we have examined the extent to which the incorporation of different cations and anions has affected each of components of the POAP/ERG nanocomposite. In this case, ERG/GC electrodes have been investigated in different solutions containing different cations and anions. The capacitive behavior of ERG/GC electrodes in the presence of different cations and anions have been evaluated at 50 mV s-1 as shown in Figs. 17A and B, respectively. The electrodes have presented negligible difference in their current response while have shown typical rectangular shape indicating an excellent capacitive behavior. Therefore, it can be concluded that graphene sheets in the POAP/ERG nanocomposite act as numerous ion-buffering reservoirs and provide for ions shortened diffusion path into the composite which results in the superior electrochemical performance of the nanocomposite.

Effective Use of the First Person in First Confession Essay -- First C

Effective Use of the First Person in First Confession "I decided that, between one thing and another, I must have broken the whole ten commandments, all on account of that old woman, and so far as I could see, so long as she remained in the house I had no hope of ever doing anything else," (page 189). This quote from the text of "First Confession" by Frank O'Connor exquisitely shows which point of view O'Connor selected for his story. Frank O'Connor chose the first-person point of view to tell his tale. One can determine this by three factors: the use of the word "I", the use of grammatical voice and the use of conveying the story through the characters. These three techniques are shown vividly throughout O'Connor's novella. The use of the word "I" in O'Connor's short story is in the text continuously with an unquestionable presence. A prime example of the usage of "I" in O'Connor's tale is first seen in the second paragraph as Jackie talks about his grandmother favoring Nora, his older sister, over him: "Nora, my sister, just sucked up to the old womanÖI was too honest, that was my trouble; and when I was playing around with Bill ConnellÖand saw my grandmother steering up the path with the jug of porter I was mortified. I made excuses not to let him into the house, because I could never be sure what she would be up to when we went in," (page 188). The application of the word "I" is an obvious and well-known method of the first-person point of view, as well as using another compatible method such as grammatical voice. Grammatical voice is a conventional technique of guiding the reader through the story using a first-person point of view. This is a... ...s. The reader is also shown that Jackie's mother dislikes her mother-in-law's mannerisms. This use of conveying the story through the characters is another method that is primarily used in first-person point of view, conventionally for its simplicity and advantage of giving several details in a short amount of time. O'Connor shows first-person point of view unremittingly in the short story "First Confession." By his usage of the word "I," O'Connor announces to the reader that he is writing in first-person, by using the method of grammatical voice O'Connor shows another technique of writing in first-person and, intertwined with grammatical voice, his conveyance of the story through the characters is his last usage of writing in the first-person point of view. These three applications of writing give the reader a sure perception of O'Connor's point of view.
