The research aimed to study the changes in the microstructure and hardness of the Ni-Ti shape memory alloy with a porous structure when the Ni and Ti metal powders are preliminarily subjected to ultrasound activation for different periods. The microstructure of the alloy surfaces was studied with using a Hitachi scanning electron microscope (SEM), and the hardness was measured with a Brinell electronic hardness tester. The results of the experiments showed that the porosity and hardness of the Ni-Ti alloy enlarged with an increase in the time of ultrasound activation of the components. The innovative aspect of this study is that prior to the synthesis of powder elements with a purity of Ni 99.9% and Ti 99.9% with an average particle size of 40 μm, they were previously subjected separately to ultrasound activation at different periods.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86403176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These issues create prerequisites for the improvement of the state health policy and, first, the drug supply system, which is an integral part of the treatment process. The financing of healthcare in Armenia is mainly formed from budget allocations and out of pocket expenditures of the population. Reducing the financial burden on the state and ensuring the rational use of drugs contributes to improving the health of the population.

The amounts of emissions are affected by the number of vehicles in traffic, vehicle technology, geometric and traffic conditions of highways and intersections, and environmental factors. Traffic flow is mostly interrupted at Intersections in local traffic, especially in city centers. Emissions of these points, where traffic behavior is changed and vehicles stop and go, are higher as compared to uninterrupted flows. In this study, current state emissions at 120 Intersection were determined by SIDRA INTERSECTION software. Then, new emissions are determined by the same software after improvement in signalization. As a result of the study, fuel consumption and pollutant emissions were calculated before and after improvement. As a result of observations at the intersection, current state fuel consumption was calculated as 1718.2, l/hour, and CO2, CO, HC, and NOX emissions were 40464.7, 3.821, 0.482, and 5.060 kg/hour respectively for the morning. After that current state fuel consumption was calculated as 1492.1, l/hour, and CO2, CO, HC, and NOX emissions were 3522, 3.116, 0.406, and 3.246 kg/hour respectively for the evening. It has been determined that there were significant differences between the current state and after improvement. Improvements in geometric conditions or signalization at intersections may result in a decrease in vehicle emissions and improve the air quality in cities.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89333546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The frequency of morbidity will increase by about 2.5 times (1). Namely, the unfavorable epidemiological picture of atrial fibrillation makes the project relevant. There are numerous studies, although intracardiac hemodynamics and hemorheologycal parameters and their role in the course of atrial fibrillation have not been studied; We have studied the hemorheological profile in patients with atrial fibrillation. Changes of rheological parameters and hemodynamics were assessed against the background of rhythm disturbances. We examined 50 patients (women-22, men - 28, the average age of 65±10) and 20 healthy volunteers. We have studied the Index of the Erythrocytes aggregability, which is the area of aggregated erythrocytes divided by the full area of the erythrocytes. These new innovative methods “Georgian Technique” is created by Georgian scientists and they are famous in the world as direct, numeral and exact [G. Mchedlishvili, 2004; N. Maeda, 2010; M. Mantskava M., 2011]. Also, all patients the studies: ECG, ECHOcardioscopy was performed. After statistical processing of the material, it was found that erythrocytes aggregability is highly impaired in patients with permanent and persistent forms of atrial fibrillation. Mean value of EAI is 41.7 ± 10.4 compared to the control group, where the average EAI value is within 25.6 ± 1.2. The Index of erythrocytes aggregability (EAI) are significantly increased in inverse proportion to the decrease of the left ventricular ejection fraction. A negative correlation was revealed between the Index of erythrocytes aggregation and the left ventricular ejection fraction (R=0.4); According to the obtained data, changes of rheological parameters deepen in the wake of disruption of intracardiac hemodynamics; This confirms the notion that a small blood vessel is the \"target\" in the case of atrial fibrillation. From hemodynamic mechanisms rheology plays an important role. They are determinants of hemodynamic processes in the body (2).","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83015294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantages of using solar devices for drying agricultural products compared with natural drying in the open air are shown. Products dried in a solar dryer have high consumer properties, the vitamin composition is preserved as much as possible in dried products, enzymes and microorganisms are inactivated, and they are also stored longer than products dried by natural drying in the open air. The high air temperature in the solar dryer significantly reduces the drying time of raw materials by 2.5-4.5 times compared to traditional drying in the sun. Solar dryers are located on any site oriented to the south in order to maximize the radiant flow of solar energy. Convective and sheet solar dryers are easy and convenient for transportation, during the day they can be moved and rotated to the sun. A large-sized helio drying device is offered mainly for small peasant farms. The proposed dryers are simple to manufacture and can be used on farms and private farms.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77250888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
