Abstract: The objective of this experiment was to synthesize aspirin from salicylic acid and acetic anhydride. The general theory behind this experiment was to study the synthesis of a drug from organic materials. During the experiment, esterification had occurred between reactants salicylic acid and acetic anhydride. Then, phosphoric acid would catalyze the reaction and water would be added to decompose the remaining acetic anhydride. Through the process of filtration, aspirin crystals were…
The outcome of simulation result is tabulated in Table 7.2. Here it is observed that results in terms of cost, standard deviation and also the CPU time get improved with respect to SFSA technique. Comparison of results of SFSA and ISFSA is presented in Table 7.3 and convergence characteristics is shown in Fig-7.1. Table 7.2 Selection of Scale Factor Scale Factor(F) Min Cost…
All five articles evidenced significant deviations in cognitive development, academic success, behavior and IQ in LBW children. The LBW consequences could significantly lower quality of life of the children and disrupt their normal growth and prevent them to catch up with the normal weight children…
personality disorder is. Which currently, a personality disorder is defined as a pervasive pattern of "inner experience and behavior" that is deviant from a person's cultural norms. These may lead to deviations in thoughts, emotionality, interpersonal relatedness, and even impulse control. Deviations in any of the above aspects would need to be pervasive, stable, present at least since adolescence, but hopefully not due to substances or another mental disorder. These ways of feeling, thinking,…
originality, but simply that the success of the Parthenon in Athens could be brought to Edinburgh. There were many who did not care what the purpose of the Parthenon replica would be, but rather that the appearance would be “purely Grecian” with no deviation from the original (Fehlmann). However, many arguments did arise against copying existing architecture, and suggestions that the monument must be based on…
equation with the R2 value, which represented the relationship between log mass and log MRMS. In Microsoft Excel, the mean O2 consumption per mass and standard deviation for how different-sized mice were affected by different temperatures, shown as MRMS values, were represented by a bar graph, with error bars representing the standard deviation for each temperature acclimation. Two slope t-tests were performed to determine a significance between the known slopes, of -0.25 and -0.33, and the…
Sarcastically and dramatically, John Updike contrasts the protagonist’s veneration of three women in swimsuits at a supermarket on a hot summer day with the crowd’s fear of the women’s deviation from accepted conduct for females. Although taken aback by near-nudity, the narrator scrutinizes the public’s judgment of the girls. Dramatizing his descriptions of the three girls, he says that the girls were wearing “nothing but bathing suits,” and “didn’t even have clothes on.” By including “didn’t…
The pertinent information for the x-variable are as follows (the data will be to two decimal spaces): the mean 80.52, the median 20, the mode , the range 40, and the standard deviation 135.14. The scatter plot does not depict a concrete linear at all. It does show that there are a few outliers. The histogram produces the best results clearly showing a shape. The shape the histogram takes is that the collected data from the x-variable…
are performing the specified trial functions set forth in the Protocol. Continued non-compliance could present a major risk to the well-being and safety of a trial subject. • Source Documentation • eCRF • Protocol • Protocol Deviation Log – reviewed by PI • Protocol Deviation Log – reviewed by PI As a CRA, protecting subjects’ safety will always be a priority. This sentiment is acted upon throughout various tasks carried out by a CRA including those reviewed in Table 1. However, whilst a CRA…
free from any deviation of attention through an aesthetic excess. Compatible with the minimalist proposal of shape, the piece has as a subtle detail, a milling cutter that holds for extra comfort in the seat, a trademark in the designer's works. In its manufacture Paulo Alves excels by quality and sustainability allied with the characteristics of traditional carpentry.…
