Abstract:
Despite the development of innovative technologies, chorioamnionitis remains a pressing problem in modern obstetrics. The aim of our study was to determine the frequency of obstetric and perinatal complications in pregnant women with chorioamnionitis. The objective of our study was to determine the frequency of obstetrics and perinatal complications in pregnant women with chorioamnionitis. Study groups were formed: Group I (main) - 100 pregnant women with chorioamnionitis, Group II (control) - 100 women with physiological pregnancy. The condition of the mother-placenta-fetus system and the functional fetal condition were assessed by Doppler ultrasound and cardiotocography. The analysis of perinatal consequences in pregnant women with chorioamnionitis was performed, in particular, a retrospective study of perinatal mortality. In the main group of patients were observed the structural changes in placenta 3.9 times more than in group II, oligohydramnios and polyhydramnios 6.9 and 5.6 times more, respectively, intrauterine growth retardation stage I was observed in 11.0% of studied in the main group, intrauterine growth retardation stage II and III were found only in pregnant women of group I (54.0% and 6.0%), respectively. In the hemodynamic disorders structure is dominated by stage II, the degree ofdisorders is 62.0%, only in women with chorioamnionitis were observed disorders in the system "mother-placenta-fetus" stage III - 9.0%.Cardiotocography analysis defined signs of fetal cardiac reactivity in 85.0% of patients. The pathological course of childbirth significantly prevailed in the studied of the main group. Intrauterine infection was diagnosed in 21.0% of cases. Early neonatal sepsis was observed in 9 (42.9%) cases, necrotizing enterocolitis in 5 (23.8%) newborns, congenital pneumonia - 7 (33.3%) cases. In the structure of antenatal fetal death, chorioamnionitis in pregnant women was diagnosed in 63.6% of patients, in the structure of early neonatal mortality - 58.3% of cases. The results of the study indicate that intraamniotic infection is a risk factor for the development of pathological pregnancy and labor with relevant perinatal complications.

Abstract:
Possibilities and prospects of correcting women's health disorders associated with hypoestrogenic conditions of various etiologies or hormonal imbalances are considered. The causes of estrogen deficiency and features of complaints in women of different ages with an emphasis on peri- and menopause are systematized. An alternative to menopausal hormone therapy (MHT) with the use of phytovitamin preparations is considered. The relationship of hormonal metabolism with vitamin and mineral status, feasibility and benefits of complex phyto-, vitamin- and mineral preparations is shown. The therapeutic efficacy of medicinal plants that are part of the complex phytopreparation "Forevia Maxi" ("Organosyn LTD") in accordance with the symptoms of premenstrual syndrome (PMS): vasomotor (shortness of breath, hot flushes, night sweats, blood pressure fluctuations), genitals and atrophy of the vagina, itching, burning, cystalgia, urinary incontinence, dyspareunia) complications, memory and cognitive impairment, decreased sexuality, libido, sleep disorders, mood swings, anxiety, depression, aggravating psycho-emotional state, osteoporotic changes. Data from clinical trials of phytoextracts are shown, which demonstrate that the effect of the components of Forevia Maxi significantly exceeds the effect of placebo, and sometimes not less than with the use of MHT. The obvious benefits of this tool and as an adjunct to the basic therapy of PMS and hypoestrogenic conditions, characterized by ease of use, good safety profile, allows you to individualize the approach to patients, which is important in cases of medical contraindications for hormone therapy. Forevia Maxi is also the most appropriate for use with MHT, as an additional component of the correction of hypothalamic-pituitary disorders and saturation of the body with essential minerals and vitamins.

Abstract:
The work is devoted to solving the scientific and technical problem of ensuring the tribotechnical properties of car parts through the use of wearresistant coatings. 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.

Abstract:
We performed an experiment to determine the resistance impact on the engine performance resulted from the engine fuel system. 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.

Abstract:
One of the spread first level methods of optimum search is learned by the steepest descent method in conditions when there are mistakes in the experiment. The steepest descent method is investigated and is successfully applied in situations, when, there are no mistakes of experiment. However, in real situations the used means of measurement always have determined errors owing to what the appropriate meanings of the response receives with mistakes. The model of the steepest descent algorithm in created, when the length of the step does not depend on the meaning of the purpose functioning. Stepping process realization algorithm and program provision in MathCAD, computer mathematic, system is designed. The realization outcome mistakes for different meaning are presented, the step movement of the optimum dot direction is shown according to function meaning and argument meaning as well. The amount needed for the tactics necessary to approach the minimum is established, the quake amplitude in the surrounding of different level experiment mistakes at the optimum search efficiency in different step conditions.

Abstract:
The aim of the research was to study and analyze peculiarities and prospects for the use of zeolite containing Geomin Forte in the treatment of covid-19 and post covid-19 condition. 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.

Abstract:
Recurrent vulvovaginal candidiasis (RVVC) is a widespread problem for today. 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. In publication described diagnosis of RVVK, the species composition of the pathogen, risk factors, impact of hormones and genetic predisposition.
