SEPARATION OF RADIUM – 228 FROM THORIUM-232 USING MnO2 - MN202 SORBENT

The work is devoted to the study of the sorption of radium-228 on the microporous ad-sorbent MN202, on the surface of which a layer of manganese dioxide is deposited. As a result of the study, a solution of radium-228 was obtained, purified from radium-224 and its decay products

4D FLOW МРТ в оценке диастолического кровотока в левом желудочке у пациентов с гипертрофической кардиомиопатией

Objective. To assess phase-contrast MRI in the evaluation of left ventricular hemodynamics changes in various forms of hypertrophic cardiomyopathy.Materials and methods. 11 patients were examined: without pathology of the cardiovascular system (n = 3), with apical (n = 3), diffuse-septal (n = 2) and focal-basal (n = 3) types of hypertrophic cardiomyopathy. All patients underwent MRI of the heart with an additional phase-contrast sequence of the left ventricular area. Postprocessing carried out in the 4D FLOW application (Siemens).Results. Data were obtained on the geometry and dynamics of vortex diastolic flows in the left ventricular of all patients. In patients with hypertrophic cardiomyopathy, an increase in the distance to the center of the vortex and a decrease in the normalized area and peak velocity of the vortex is determined. The diffuse-septal type is characterized by a minimal vortex peak velocity; apical type - by the maximum vortex sphericity index. For patients with a focalbasal type of hypertrophic cardiomyopathy the maximum changes in blood flow are determined in late diastole (absence of vortexes).Conclusion. 4D FLOW Phase-contrast MRI allows identifying and assessing LV vortical flow. Quantitative analysis can be used to characterize the remodeling of LV blood flow of various types of hypertrophic cardiomyopathy.Цель исследования: оценить изменения гемодинамики левого желудочка с помощью фазово-контрастной МРТ у пациентов с различными формами гипертрофической кардиомиопатии.Материал и методы. Обследовано 11 пациентов: без патологии сердечно-сосудистой системы (n = 3), с апикальной (n = 3), диффузно-септальной (n = 2) и фокально-базальной (n = 3) формами гипертрофической кардиомиопатии. Всем пациентам выполнено МРТ-исследование сердца с дополнительной фазовоконтрастной последовательностью области левого желудочка. Постпроцессорная обработка проведена в приложении 4D FLOW (Siemens).Результаты. Получены данные о геометрии и динамике вихревых диастолических потоков в левом желудочке у всех пациентов. У пациентов определяется апикальное смещение вортекса, уменьшение нормализованной площади и пиковой скорости вортекса. Диффузно-септальная форма характеризуется минимальной скоростью вихревого потока, апикальная форма – максимальным индексом сферичности вортекса. Для пациентов с фокально-базальной формой максимальные изменения кровотока определяются в позднюю диастолу (отсутствие вортексов)Заключение. Метод 4D FLOW фазово-контрастной МРТ позволяет выявить и оценивать изменения диастолических вихревых потоков в левом желудочке. Количественный анализ данных можно использовать для характеристики ремоделирования кровотока в левом желудочке при различных типах гипертрофической кардиомиопатии

Methods of calculating the belt foundation on the elastic ground base of winkler type

Strip foundations on an elastic soil foundation and on a Winkler-Type elastic foundation were used in the construction of buildings and structures from the most common types of shallow foundations. The article presents the results of studies related to the analysis of the features of the formation of structural solutions of strip foundations. It was found that various aspects associated with the development of multifactor mathematical models that determine the design parameters and modern regulatory requirements, provide conditions for not exceeding the limiting conditions of structures and soil base. It improves the functional quality indicators of strip foundations. Based on the results of the study, the need to study the possibilities of using strip foundations (beams on an elastic base) was identified, and the main provisions of the model of a Winkler-Type soil base (with one, two and three bed coefficients) were considered. An algorithm is developed for determining the initial parameters and numerical solution of boundary value problems. The prospects of a shallow foundation model with a variable cross section or a beam of finite length with variable stiffness, which is accepted as one of the options for modifying a typical structural solution of a strip foundation, are shown
