for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
In this work, the possibility of using reactions electrogenerated titrants with phenolic compounds was studied and a method for their coulometric determination in medicaments by galvanostatic coulometry developed. The research objects were: rutin, salicylic acid drugs containing such as «Ascorutin», «Salicylic Paste» Ointment» Russian manufacture. Electrogenerated halogens (Cl2, Br2 I2) hexacya...
The fact that oxidation, as one of the main routes of phase I metabolism of drugs, follows by conjugation reactions, and also formation of nitrenium ion as one of the clozapine oxidation products, directed us to investigate the oxidation of clozapine (CLZ) in the presence of nucleophile. The oxidation of clozapine (CLZ) has been studied on a glassy carbon electrode in the absence and presence o...
Experiments were performed to test the hypothesis that a reduction in the space constant contributes to slow conduction in the infarcted myocardium of dogs 5-8 days after coronary artery occlusion and reperfusion. Standard microelectrode techniques were used to measure action potential characteristics and conduction velocity parallel to fiber orientation in normal and infarcted ventricular epic...
