4-d]thiazoles and antimicrobial activity. INTRODUCTION Benzothiazoles are heterocyclic compounds with multiple application and although they have been known from long ago to be biologically active.1-3 Recently, Racane et al4 have described the synthesis of bis-subsituted amidinobenzothiazoles as potential anti-HIV agents. The condensation of dithio-oxamide with aromatic aldehyde was described by Ephraim.5 More recently, Johnson and Ketcham6 studied the reaction and established the structure of
Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20,000Hz. As the cycles per second increases, the smaller the wavelengths become, therefore there is a higher frequency which will cause
to controlling an outcome. A dialectical (Divided) method of argument by 19th Century German philosopher, G.W.F. Hegel. It is a method Comprised of Thesis, antithesis, and synthesis. The Hegelian Dialectic. A process where the contradiction between the Thesis and Antithesis resolves to a higher level of truth, the synthesis. Also knows as the Problem, Reaction, Solution. Its getting to the truth by exchange of logical arguments. When manipulating this method a person or group of people are swayed
Sarai Michel APL&C, Period 1 Mrs. Galvan September 23, 2015 Synthesis Process Essay To whom may be concerned: It has recently been brought to my attention that our school is looking to adopt a sustainable menu into our meal program and I would like to give my viewpoint on the matter. As one many students here at Oxford Academy this change will affect me directly. Although people may at first oppose this conversion I think if we are able to overcome the first obstacles, this change would bring a
Synthesis of Articles I currently work for a university that built an entire Adult Program based on the premise that their market would be the mid-level manager that already had a job. Most of the employers paid for the students to attend college in order to earn a degree. They were not going to earn a promotion, they already had the promotion and needed the degree to solidify their current position. As the job market has changed, the university had to change also and so has the enrollment of the
Results: Limiting Reactant: Eq 1 Limiting reactant = Benzoin Theoretical yield of Benzil: Eq 2 Theoretical Yield Benzil | 0.296 g | Mass of Crude Benzil | 0.188 g | Mass of Final Benzil | 0.127 g | % Yield | 43% | % Recovery | 66% | Table 1: Mass of crude/final Benzil, % yield, and % recovery Percent Yield: % Yield = (Final product/Theoretical product) x 100 Eq 3 = (0.127 g/0.296 g) x 100 = 43% yield Percent Recovery
The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th, 2011 Purpose: The purpose of this lab was to synthesize aspirin, determine the theoretical yield, compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron (III) chloride to the product. Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin)
Protein Synthesis Protein Synthesis is the process whereby DNA (deoxyribonucleic acid) codes for the production of essential proteins, such as enzymes and hormones. Proteins are long chains of molecules called amino acids. Different proteins are made by using different sequences and varying numbers of amino acids. The smallest protein consists of fifty amino acids and the largest is about three thousand amino acids long. Protein synthesis occurs on ribosomes in the
For nearly half a century, a movement has been underway to establish a high-quality, comprehensive set of international accounting standards, with the goal of facilitating international trade and investment. In the global capital market, differences in the rules of accounting for the purposes of recognition, measurement, and reporting of financial results have impaired the smooth transfer of information across borders. Given that it accounts for nearly a third of the global market, there is considerable
The purpose of this essay is to discuss the Islamization of Persia in relation to the Samanid and Buyid Dynasties. The synthesis of Persian culture and Islam was not an immediate result of the Arab expansion into Iran and there is certainly a lack of research on the subject. However, in this essay, I will attempt to explain the contributions of the Samanid and Buyid dynasties to this synthesis with a focus on the attempts of the Samanid Dynasty at centralization and a unified identity through religion
