Abstract:

Based on IR and PMR spectra there are identified cyclic derived ketosulfides 1,3-dioxolanes, which in addition to self-interest may be active reagents. Opening of a cycle 1,3-dioxole new system is implemented by organomagnesium compounds. Functional and unsaturated derivatives of cyclic ketals are characterized by physico-mechanical properties and spectroscopic methods.

Abstract:

A method to evaluate the octane number of automobile gasoline by proton magnetic resonance (PMR) spectrometry has been studied. Twelve samples of marketed winter gasoline, whose octane numbers and compositions were identified according to the ASTM standards, and high-olefin gasoline were used to supplement the insufficient coverage of a previous report with additional data. Then, a linear regression equation regarding the relationship between the octane number and PMR data was prepared from the PMR spectra of the 21 samples used for the previous report, whose octane numbers were known, and the

BackgroundGiant cell arteritis (GCA) is the most common form of systemic vasculitis in the elderly. The disease is characterized by a remarkable heterogeneity in terms of clinical picture, histologic pattern of the affected vessels, pathogenetic mechanisms and treatment selection strategies. Approximately half of GCA patients present with polymyalgia rheumatica (PMR), while 20% of PMR patients will develop GCA during follow-up. Organ or life-threatening complications of GCA, include vision loss, strokes, aneurysm formation and accelerated atherosclerosis. The clinical heterogeneity along with

Abstract:

AbstractProton magnetic resonance (PMR) spectra and terahertz IR spectra of Vectra A950 fibers and granules and Armos fibers before and after heat treatment were obtained and analyzed in order to understand the molecular mobility mechanisms that ensure the self-organization and restructurization of these rigid-chain liquid-crystal polymers, as well as their similarity and difference. It is shown that large-scale thermal (quasi-segmental) mobility in such LC polymers is due to the reptation of macromolecules with respect to each other and the conformational transitions necessary for the motion
