We have shown for the first time, connecting QM methods with QTAIM analysis and using the methodology of the sweeps of the energetical, electron-topological and geometrical parameters, that the tautomerisation of the wobble guanine·thymine (wG·T) DNA base mispair into the wG(*)·T(*) base mispair induced by the double proton transfer (DPT), which undergoes a concerted asynchronous pathway, is no...

We develop an arithrretic of complete permutations of sy-ilmetric, integral bases; this arithmetic is comparable to that of perfect systems of difference sets with which there are several interrelations. Super-position of permutations provides the addition of this arithmetic. Addition if facilitated by complete permutations with a certain “rplitting” property, allowing them to be pulled apart a...

Discourse markers, a group of pragmatic elements, are used widely in our daily communication. Among these markers, well is found to be the most frequently used one in conversation. Although much research has been carried out on its theoretical bases such as its definition, functions and categorizations, few studies have taken a multimodal approach in analyzing this marker. The aim of the presen...

The acidosis that occurs during clinical anaesthesia was formerly thought to be metabolic in origin because of inefficient carbohydrate breakdown in the unconscious state (Van Slyke, Austin, and Cullen, 1922). More recent authors (Taylor and Roos, 1950; Beecher and Murphy, 1950) have suggested that the acidosis is respiratory, due to defective ventilation, and the present work was undertaken to...

objective: diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. the objective of this project is to check out the polymorphism at the exon 8 region of dgat1 gene using pcr-sscp technique in iranian water buffaloes (bubalus bubalis). recent activities have shown that a significant association between lysine at amino acid position 232 wi...

We developed an original base plate to support both the patient's head and a Leksell stereotactic skull frame during frame placement in the supine position. The base plate is made of transparent acrylic board with holes at the posterior posts for injection of local anesthetics and maneuver of fixation screws through them. A stable and comfortable position of the patient's head in a supine posit...
