the monitoring and reporting of adverse drug reactions (adrs) in hospitals aims to identify and quantify the risks associated with the use of drugs. the present study was performed to characterize the rate and the pattern of adrs, due to cardiovascular drugs and anticoagulants, in a tertiary care teaching hospital. for this purpose, all the patients treated with cardiovascular drugs and anticoa...

B4C–Al2O3 composite powder was produced by aluminothermic reduction in Al/B2O3/C system. In this research, microwave heating technique was used to synthesize desired composite. The ball milling of powder mixtures was performed in order to study the effect of mechanical activation on the synthesis process. The synthesis mechanism in this system was investigated by examining the correspondi...

Reaction 1 occurring with reaction 2 involves carbon dioxide fixation. Koepsell & Johnson (1942) obtained a cell-free extract from Clo8tridium butylicum which converts pyruvic acid into acetic acid, carbon dioxide and hydrogen, and requires phosphate for the reaction. Later Koepsell, Johnson & Meek (1944) found that inorganic phosphate is taken up and labile phosphate appears. The overall react...

Each mole of oxyhemoglobin iron converted to methemoglobin causes the oxidation of 1.5 mol of nitrite to nitrate and consumes 1 mol of protons. No oxygen is liberated. The overall reaction has two simultaneously occurring parts. In the beginning the rate-limiting reaction converting O2Hb to metHb is directly proportional to H+ and NO2- concentrations and is independent of metHb. The second port...

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Strides in information technology and improvements in networking technology have set the pace for rapid growth in new applications of electronic commerce in a variety of settings. Business to business (B2B), business to customer (B2C), customer to business (C2B), and customer to customer (C2C) have become prevalent business channels and have reshaped the ways that business transactions are cond...
