Актуальність обраної теми обумовлена демократизацією суспільства, становлення громадянського суспільства та держави соціальної злагоди неможливі без вивчення та врахування гендерної проблематики, адже розвинуте громадянське суспільство – це перш за все суспільство з рівними можливостями для самовизначення та самореалізації як чоловіків, так і жінок. Гендерна демократія є системою волевиявлення двох статей – жінок і чоловіків – у громадянському суспільстві як рівних у правах і можливостях, що законодавчо закріплені й реально проявляються в усвідомленні політико-правових принципів, у діях, розбудові громадських і державних структур з урахуванням гендерних інтересів і потреб. Гендерна рівність – це один з індикаторів рівня демократизації суспільства, його цивілізованості. Суть проблеми полягає не в тому, щоб надати однакові права особам різної статі створити такі умови суспільного життя, щоб жінка і чоловік були спроможні реалізувати себе повноцінно в особистому, громадському, професійному житті, адже гендерна рівність це перш за все рівність можливостей та рівність…

Increasing heat recovery in industry and household is the key point for reduced energy consumption. It can largely be achieved by improved efficiency of both process plants and equipment units. The optimal determination of the network structure with the processing equipment is the task of process network synthesis, which includes the integration of the process design with optimal heat integration. Since the selection of a process network during synthesis has major influence on the cost, the reliability, and the level of heat integration, these three items must be considered simultaneously in process synthesis, implementing more efficient heat transfer systems with enhanced design. To achieve it, a general approach and modeling tool that simultaneously covers the cost, reliability, and level of heat integration targets is highly demanded for optimal process network design. The present paper discusses the optimal selection of heat exchange equipment of plate type for process network synthesis using P-graph approach.

Autoimmune polyendocrine syndrome type 1 (APS1) is a monogenic disease, defined by the presence of two of the three major components: hypoparathyroidism, primary adrenocortical insufficiency and chronic mucocutaneous candidiasis. In total, more than 30 manifestations of APS1 are described, while the patient can have up to 20 autoimmune diseases. Therefore, the management of patients with APS1 requires a multidisciplinary approach. The article presents a literature review on the treatment of one of APS1 classic endocrinopathy — hypoparathyroidism. Standard therapy of hypoparathyroidism is oral calcium and active vitamin D supplementation.Biological effects and metabolism of parathyroid hormone, vitamin D, calcium and magnesium are closely linked. Calcitriol doesn’t produce all the functions of the parathyroid hormone. Conventional treatment has several disadvantages: kidney damage; hyperphosphatemia that contributes to calcification in tissues; impaired bone remodeling. Patients with coexisting hypoparathyroidism and malabsorption syndrome are less responsive to conventional therapy,…

The air cooler can be used for the cooling of gas turbines and it presents certain difficulties for the calculation model generation. The reason is that the cooling system graph of the-state-of-the-art turbine can consist of 1000 and even more channels. Such large systems are successfully simulated using THA (Thermal & Hydraulic Analysis) Software Package. The method realized by THA for cooling systems can also be used for the air cooler design. However, the inclusion of the heat exchanger into the general diagram considerably complicates the design diagram. In this connection it was recommended to represent the heat exchanger as one channel whose properties totally suit for different types of heat exchangers. To substantiate this approach we analyzed the operation of the tubular heat exchanger with such heat carriers as air-air, air-water and water-water using the THA software package. It was established that the heat exchanger efficiency depends mainly on the relationship of the flow-rate heating power of heat carriers. A slight scatter in the heat exchanger efficiency data is…

There were significant differences in the performance of…

The endogenous intoxication syndrome (EIS) is one of the leading syndromes of many pathological processes. EIS is a result of the accumulation of harmful substances. This accumulation depends on formation and excretion of bile, and gallbladder (GB) condition, because intrahepatic and intraductal bile stasis, provoked by cholelithiasis, strictures and deformations of bile ducts, cellular and enzymatic dysfunctions, worsens the detoxifying function of bile system. Together with this, persistent inflammation increases the amount of proinflammatory mediators.The objective: was to estimate EIS activity according to hematological indexes in patients with coronary heart disease (CHD), namely, non-stable angina pectoris, with various GB condition.Material and methods. We analyzed the data of 116 patients, which were divided into groups according to GB condition: intact GB; sludge, cholesterosis and GB polyps; GB body deformations; GB neck deformations and cholecystitis in anamnesis; cholelithiasis; cholecystectomy in anamnesis. According to blood analysis, we counted the cellular indexes of…

The article presents the experience of acute respiratory infections (ARI), influenza in 2009–2019, infectious complications of ARI / flu, objective studies and indications for hospitalization. The conclusion is made about the need for early administration of direct antiviral drugs (SPP). In all cases of detection of viral bacterial pneumonia (PFS), hospitalization is indicated due to the high risk of rapid formation of acute lung injury (ARP), acute respiratory distress syndrome (ARDS), especially in individuals with obesity, diabetes mellitus and late circulation. The main treatment tactic is the use of PPP and antibiotics. Respiratory support for PFS using non-invasive and invasive ventilation (NIVL, IVL) is presented. The choice of antibiotics depends on the severity and type of infectious complication, the risk of strains resistant to methicillin.

To study seismic resistance of the box for the metering unit of gas flow-rate required to ignite the flare system we used the calculation methods developed on the basis of the method of finite elements and the software designed to define the mode of deformation and the dynamics of structures for the three-dimensional statement. To construct the simulation model, we took into account all the elements that affect the strength and the efficiency of the real structure during possible earthquakes. Structure elements were simulated using the sets of arbitrary oriented rods and lumped masses with inertia moments and those rods were connected absolutely rigidly with each other and using also elastically damped elements. The rod elements with distributed parameters took into consideration all the types of deformations that occur during the vibrations. The plate components of the structure were simulated using the grids made of the rods taking into consideration the ductility and inertia properties of its elements. Lumped masses in the rod connections were used to take into account the masses…
