Nuclear Polarization of Molecular Hydrogen Recombined on a Non-metallic Surface

The nuclear polarization of $\mathrm{H}_2$ molecules formed by recombination of nuclear polarized H atoms on the surface of a storage cell initially coated with a silicon-based polymer has been measured by using the longitudinal double-spin asymmetry in deep-inelastic positron-proton scattering. The molecules are found to have a substantial nuclear polarization, which is evidence that initially polarized atoms retain their nuclear polarization when absorbed on this type of surfac

Полинейромиопатия критических состояний (обзор литературы)

Neuromuscular disorders are extremely common in critically ill patients; they significantly affect the recovery time and limit the quality of subsequent  life. Until now, it is difficult to assess the presence of such disorders in intensive care units. The presented literature analysis of the current state of  the issues of epidemiology, pathogenesis and pathophysiology of critical illness polyneuromyopathy (CIPNM) determines the current directions  in the diagnosis and treatment of this pathology Нервно-мышечные расстройства чрезвычайно распространены у больных в критическом состоянии, они значительно влияют на сроки  выздоровления и ограничивают качество последующей жизни. До сих пор оценка наличия таких нарушений в отделениях реанимации  и интенсивной терапии представляет трудности. Представленный анализ литературы современного состояния вопросов эпидемиологии,  патогенеза и патофизиологии полинейромиопатии критических состояний (ПНМКС) определяет актуальные направления диагностики  и лечения этой патологии

The HERMES Polarized Hydrogen and Deuterium Gas Target in the HERA Electron Storage Ring

The HERMES hydrogen and deuterium nuclear-polarized gas targets have been in use since 1996 with the polarized electron beam of HERA at DESY to study the spin structure of the nucleon. Polarized atoms from a Stern-Gerlach Atomic Beam Source are injected into a storage cell internal to the HERA electron ring. Atoms diffusing from the center of the storage cell into a side tube are analyzed to determine the atomic fraction and the atomic polarizations. The atoms have a nuclear polarization, the axis of which is defined by an external magnetic holding field. The holding field was longitudinal during 1996-2000, and was changed to transverse in 2001. The design of the target is described, the method for analyzing the target polarization is outlined, and the performance of the target in the various running periods is presented

Substantiation of the Expediency to Use Iodine-enriched Soya Flour in the Production of Bread for Special Dietary Consumption

We have studied the possibility of using iodine-enriched soy flour in the process of making bread for people suffering from iodine deficiency, diabetes and celiac disease. The organoleptic, physical-and-chemical, and microbiological indicators have been investigated, as well as the content of toxic elements and iodine content in the developed soy flour. The rationally permissible formulation ratios have been proven experimentally. The quality indicators confirmed the possibility of using enriched soy flour in the process of making bread for special dietary consumption.The conducted complex of studies provides recommendations for technologists for production of bread with special dietary properties. That will make it possible to expand a range and to fill the market with products, which are in short supply now. A lack of the mentioned products is about 15 % of the total production of bakery products. We established that the iodine content is 50 μg per 100 g in the developed soy flour. The developed flour complies with the regulatory and technical documentation for food soy flour in terms of quality and safety. The rational dosage of the developed soy flour to green buckwheat flour is 10 % in new bread formulations. It will be rational to replace 15 % of buckwheat flour with 10 % of the developed soy flour and 5 % of carrot or beet powder in products with vegetable powders.The bread developed according to new formulations complies with DSTU 4588 for "Bakery products for special dietary consumption" in terms of organoleptic and physical-and-chemical parameters. The content of organically bound iodine is 48.9; 49.4; 50.0 mcg per 100 g 72 hours after baking in the bread made by the new formulations.Our study has made it possible to state that bread that is made according to the new formulations satisfies 1/3 % of the daily need for iodin

Analysis of long-term prognosis indicators of dispersion mapping in patients with cardiac pathology

Purpose: to evaluate the use of indicators of dispersion mapping for the long-term prediction of adverse cardiovascular events in patients with cardiovascular diseases (CVD). The study included data of 217 people with using short recordings in dynamics throughout the year (winter, spring, summer and autumn). The 1 st group consists of 64 patients with hypertension, the 2 nd group - 44 patients with coronary heart disease, the 3rd - 30 patients with cardiomyopathy and in the 4 th group of 28 patients with coronary artery disease and diabetes mellitus. The control group consisted of 51 healthy individuals (18 men and 33 women) ranging in age from 29 to 53 years. Cardiac output was higher in the group of survivors (54,6 ± 0,5%) compared with the group with unfavorable outcome (33,8 ± 2,2%). The average values of all the indicators of dispersion mapping were higher in the group of death with the exception of heart rate index/IMM, indicating more severe violations. Noteworthy increase in 2 times the rate of alterative T wave at tT1 (Tbig) and T2 (Tmax) points. The sensitivity and specificity of the prediction of fatal outcome during 3 years of observation for record IMM > 25% was 54% and 61%
