Therefore we designed a tool for creating artificial resistance in the fuel pipe for determining resistance contamination in the fuel system. The artificial resistance between high pressure pump pipe and engine fuel filter was created in the field and laboratory then the diagnostic program EEM3 was used in the experiment. We tested the resistance by the pipe and decreased the pipe diameter of the fuel flow resistance from 8.5mm to 2.3 mm with 18 versions. As a result of the test, the basic indicators of the engine were changed when pipe diameter reached 6.5mm from 8.2 mm. The certain change on cyclic fuel supply occurred when the fuel flow increased and pipe diameter dropped. Moreover, the basic indicators of fuel consumption, torque and engine power were changed. It influences to the basic indicators due to the fuel filter contamination and regression of permeability proficiency then the engine will lose out the fuel.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81057455","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 synthesis of the main types of wear of car parts and ways to improve their tribotechnical properties was carried out, which allowed to substantiate the feasibility of using wear-resistant coatings to restore and strengthen them.An urgent problem is the reasonable search and development of highly efficient, easy-to-use technologies for the restoration of parts to improve the performance of cars. Solving this problem requires the introduction into practice of strengthening and restoring car parts wear-resistant coatings. Summarizing the results of research on the main types of wear of car parts allowed us to conclude that they work in conditions where operating loads (pressure, temperature, environmental action, etc.) perceive mainly their surface layers, and therefore it is enough to restore not all parts but only worn surfaces by applying wear-resistant coatings.It has been proven that to improve the performance of car parts, it is important to choose the right simple and affordable ways to apply coatings that will increase their service life. It is substantiated that among the methods of applying wear-resistant coatings are the most common, cheapest and simplest methods of gas-thermal spraying, namely gas-flame spraying and electric arc spraying. Restoration and strengthening of car parts by applying wear-resistant coatings has solved the problem of providing their resource, which is not inferior to the resource of new parts.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81789910","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}

Symptoms of the disease significantly reduce women life quality. It is common reason for medical help. Clinical sings of vaginal candidiasis are nonspecific. The most common method of diagnosis - microscopy of vaginal discharge, does not always provide enough information. Among the causative agents of candidiasis, Candida albicans and Candida nonalbicans have different prevalence in different regions of the world.Resistance to antifungal drugs is increasing due to it widespread applying.Risk factors for RVVK are: antibiotic therapy, immunodeficiency conditions, diseases of the gastrointestinal tract, contraceptives, corticosteroids, hormonal disorders of women, allergic diseases. Recent studies indicate the multifactorial cause of candidiasis, especially the imbalanced composition of the vaginal microflora and genetic predisposition. Resistance to antifungal drugs is increasing, especially to Fluconazole, that is most often applied in clinical practice.The role of immunoregulatory mechanisms is reflected in the reduced activity of immunity in the vagina. Changes in Tol-like receptor (TLR) genes have been reported in women with RVVC. Also, interlexins can lead to a prolonged inflammatory process in the vagina. Currently, polymorphism of the mannose-binding lectin gene in women with RVVK relevant topic for research. That changes may be a reasone of recurrence.Determination of mannose-binding lectin for diagnostic and therapeutic purposes is promising research area. There is increasing scientific interest in the study of this pathology.

Antioxidants are substances that the human body constantly needs in order to maintain it in a normal state, which means maintaining the necessary balance between free oxidative radicals and antioxidant forces, the role of which is played by antioxidants.Vitamin E increases the body's nonspecific resistance, and by activating the synthesis of cytokines, tocopherol stimulates its own anti-inflammatory activity. The effect of vitamin E is to stimulate the reproduction of immune cells, systems that need to quickly multiply when they meet the source of a possible disease. In the body, this process is called mitogenesis.The pharmacodynamic effects of tocopherol are synergistic when combined with vitamins C and A. Retinol provides formation of immune (protective) cells, lining respiratory tract and gastrointestinal tract, serving as a natural barrier to infection. Medicine will enhance possibilities of adaptation of the organism to the changed environment, because, in many cases, it is very difficult to protect the population from the impact of the negative factor (including ionizing radiation, natural disasters, etc.) According the study results “Geomin Forte” can be used during intoxications (used as the best sorbent for food, infectious, occupational intoxications, chronic metals and chronic exposure to radiation). As well as when the functional state of the immune system is impaired and fatigue and as an adjunct for allergic diseases. The mineral zeolite (clinoptilolite), the 500 mg activated clinoptilolite \"Geomin Forte\" developed by us is characterized by antioxidant action. Unlike the conventional antioxidants, it stimulates the body's endogenous antioxidant system and is a direct-acting oxidoreductive agent. Its activated natural mineral zeolite (clinoptilolite) acts directly on the cell membrane as a surface-active donor of electrons.With its oxidizing effect, \"Geomin Forte\" is 200 times more than vitamins C and E. Used in combination with antioxidant therapy in the context of standard treatment for the following diseases: Diabetes mellitus, accelerated aging process; alzheimer's disease; parkinson's disease; endocrine pathologies; atherosclerosis and ischemic heart disease, hypertensive disease, stroke, rheumatism.","PeriodicalId":19855,"journal":{"name":"Pharmacy World & Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74085623","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}
