Study of the oxidation of 3,5-di-tert-butylcatechol with molecular oxygen catalyzed by of 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II). M. Hassanein, S. El-Khalafy*, S. Shendy Tanta University, Faculty of Science, Department of Chemistry, Tanta 31527, Egypt. Abstract 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II) showed good catalytic activity towards oxidation of 3,5-di-tert-butylcatechol to 3,5-di-tert-butyl-benzoquinone by dioxygen in dimethylformamide. The oxidation reaction was followed
Bryan Montgomery SOC 105 A Professor Angelo James Sirigotis ID# 1413360 Cessation of Democracy An analysis of the mechanics of the recent elections held in the United States illuminates the overall theme portrayed in Weber’s essay on Bureaucracy and demonstrates a spot-on representation of his ideals in Charismatic Authority. In Bureaucracy, Weber describes the bureaucratic structure as a nearly unbreakable and regenerative entity. He argues that, “Once fully established, bureaucracy is among those

The purpose of action research is not only collect data but to aim for useful data that can be used to change the lives around us. According to Esterberg, “action researchers see knowledge as power” (pg. 137) thus meaning if individuals can see the inequality around them and are educated on it then they can use the “power” to change society and promote equality. 2. Describe the three varieties of action research. The three varieties of action research include participatory action research (PAR)
Studies on chemically deposited Pb(S,Se) thin films J. D. Chaudhari *, R.D. Chaudhari * *, Dr. R. H. Bari + Department of Physics, G. D. M. Arts, K. R. N. Commerce & M. D. Science College, Jamner.Pin – 424 206 Abstract : Thin films of Pb(S,Se) [lead sulfoselenide] have been prepared on glass substrate at 50°C by simple chemical bath deposition technique. The starting materials used for deposition were lead acetate, tri-sodium citrate, sodium sulphite and elemental selenium

Brain disorders are major concern of modern world in terms of economic liability and human suffering with the increased number of aged population as a result of the long life expectancy. The main challenge in the treatment of many of the neurodegenerative diseases is the presence of a polarized layer of endothelial cells that comprises the blood–brain barrier (BBB) which precludes access of systemically administered medicines to brain tissue. Currently more than 98% of all small molecules
Objectives: The aim of this study is to find out the prevalence of neurological manifestations of falciparum malaria and the outcome of falciparum malaria in general and of neurological involvement of falciparum malaria in particular. Materials and Methods: A prospective cross-sectional hospital-based study of 125 adult falciparum malaria patients using simple, direct, standardized questionnaire including history, lab investigations and neurological examination from January to December 2014. Results:
