Sliding Mode-Based Traction Control for An Autonomous Martian Rover
Authors: Bowne Julian , Scacchioli Annalisa
Published: June 2021

A traction control system was developed for an autonomous Martian rover using a sliding mode controller. The main inspiration for this project was NASA’s Mars rover, Curiosity, which suffered severe wheel damage due to the lack of an effective traction control system. A control system was sought out to effectively prevent wheel damage, slippage, and soil failure for a Martian rover. It was initially hypothe-sized that a sliding mode controller would be most effective to control the vehicle’s traction. A Simulink model was created with a deformable soil-rigid tire mathematical model in order to simulate the traction control system. The sliding mode controller was tested to be more robust and stable compared to a proportional-integral-derivative (PID) controller for the rover. The results elaborate the possible applica-tions for this project, which spans across commercial and military rovers, rescue robots, and planetary rov-ers in the private and global space industry.
Gamma irradiation-mediated inactivation of enveloped viruses with conservation of genome integrity: Potential application for SARS-CoV-2 inactivated vaccine development
Authors: Abolaban Fouad A. , Djouider Fathi M.
Published: June 2021

Radiation inactivation of enveloped viruses occurs as the result of damages at the molecular level of their genome. The rapidly emerging and ongoing coronavirus disease 2019 (COVID-19) pneumonia pandemic prompted by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now a global health crisis and an economic devastation. The readiness of an active and safe vaccine against the COVID-19 has become a race against time in this unqualified global panic caused by this pandemic. In this review, which we hope will be helpful in the current situation of COVID-19, we analyze the potential use of γ-irradiation to inactivate this virus by damaging at the molecular level its genetic material. This inactivation is a vital step towards the design and development of an urgently needed, effective vaccine against this disease.

Published: June 2021

We carried out a full-coverage survey of the Yautepec Valley in the 1990s to reconstruct demography and settlements and their changes through time. We investigated the extent to which well-documented developments in the adjacent Basin of Mexico were paralleled in Yautepec, as well as the impact of regional empires and economies on local society. Our analyses focused on Teotihuacan relations in the Classic period and relations with the Aztec empire and the Mesoamerican world system in the Middle and Late Postclassic periods. In addition to locating, mapping, and describing sites and taking grab-bag artifact collections, we also made a series of systematic intensive surface collections (5 × 5 m) and test excavations at samples of Classic and Postclassic sites. In this paper, we describe the survey and changing settlement patterns in the Yautepec Valley. We also present several analyses of changing patterns of urbanization through the Prehispanic era. We conclude with a synthesis of changing social and cultural dynamics in this region.
Investigations of the characteristics and performance of modified polyethersulfones (PES) as membrane oxygenator
Authors: Mostafavi Amir Hossein , Hosseini Seyed Saeid
Published: June 2021

The modification of membrane oxygenators to minimize protein adsorption onto the surface is often accompanied by the loss of membrane performance. This study aims to explore polyethersulfone (PES) as a new material for membrane oxygenator applications and to assess its potentials. Accordingly, different modification techniques are applied to improve surface properties of PES membranes. To achieve this goal, two separate modification methods including incorporation of TiO2into the membrane matrix as well as grafting polyethylene glycol (PEG) through oxygen plasma treatment are developed and the effects are examined. The results reveal that protein adsorption to the nanocomposite membrane containing 0.50 wt. % TiO2and the grafted membrane decreased by 47 and 31%, respectively. In terms of performance, permeability and oxygen transfer rate of all modified membranes exceeded 808 GPU and 2.7 × 10−4 mol·m−2·s−1, respectively. Contact angle analysis revealed signs of hydrophilicity enhancement of membranes after modifications. The findings suggest that upon proper modifications, membranes based on PES could be considered as promising candidates for membrane oxygenator applications and deserves further investigations.
Russland und der Westen: Von „strategischer Partnerschaft“ zur strategischen Gegnerschaft
Authors: Adomeit Hannes
Published: June 2021

Kurzfassung

Gegen Ende der Jelzin-Ära erhoben Deutschland und die EU Russland zu ihrem „strategischen Partner“. Diese Charakterisierung der Beziehungen wurde von den beiden Akteuren nicht als Teil einer entfernten Vision, sondern als vollendete Tatsache betrachtet. Entsprechend sollten die mit Putins Russland vereinbarten „Modernisierungspartnerschaften“ lediglich als Ausfüllung der „strategischen“ Partnerschaften dienen. Derartige Vorstellungen waren schon zum Zeitpunkt ihrer Verkündung realitätsfremd. Die Beziehungen zwischen Russland und dem Westen führten von der Illusion einer strategischen Partnerschaft zur Wirklichkeit einer strategischen Gegnerschaft. Diese Entwicklung ist nicht als zusammenhanglose Anhäufung von Konflikten, geschweige denn Missverständnissen und Fehlwahrnehmungen zu verstehen, sondern als eine prinzipielle, nachhaltige und innenpolitisch in der Machtstruktur des Systems Putin verankerte und von der Moskauer Machtelite bewusst herbeigeführte Orientierung. Dies stellt eine strategische Realität dar, die eine entsprechende Antwort der westlichen Staatengemeinschaft verlangt.
Identification of Multiple Noise Sources Improves Estimation of Neural Responses across Stimulus Conditions
Authors: Weber Alison I. , Shea-Brown Eric , Rieke Fred
Published: June 2021

Most models of neural responses are constructed to reproduce the average response to inputs but lack the flexibility to capture observed variability in responses. The origins and structure of this variability have significant implications for how information is encoded and processed in the nervous system, both by limiting information that can be conveyed and by determining processing strategies that are favorable for minimizing its negative effects. Here, we present a new modeling framework that incorporates multiple sources of noise to better capture observed features of neural response variability across stimulus conditions. We apply this model to retinal ganglion cells at two different ambient light levels and demonstrate that it captures the full distribution of responses. Further, the model reveals light level-dependent changes that could not be seen with previous models, showing both large changes in rectification of nonlinear circuit elements and systematic differences in the contributions of different noise sources under different conditions.
Insider Activists and Secondhand Smoke Countermeasures in Japan
Authors: Arrington Celeste L.
Published: June 2021

Long considered a smoker’s paradise, Japan passed its strictest regulations yet on indoor smoking in 2018 with revisions to the Health Promotion Law and a new ordinance in Tokyo. Timed for the Tokyo Olympics, both reforms made smoking regulations stronger and more legalistic despite reflecting distinctive policy paradigms in their particulars. The national regulations curtailed smoking in many public spaces but accommodated smoking in small restaurants and bars. Tokyo’s stronger restrictions emphasized public health protection by exempting only eateries with no employees. I argue that fully understanding these contemporaneous reforms requires analyzing insider activists: state actors who participated in the tobacco control movement or had sustained interaction with it during earlier reform waves. Case studies drawing on interviews and movement and government documents illustrate the mechanisms insider activists can access because they straddle multiple fields. This article contributes to scholarship about ideas, policy entrepreneurship, and the blurry line between insiders and outsiders in policymaking.
Lombok’s Tsunami and Stock Abnormal Returns
Authors: Suryani Ani Wilujeng , Pertiwi Karina Dian
Published: June 2021

Natural disaster often brings damage to the economy, including the decrease of stock’s market value. For this reason, this study aims to determine the effect of the tsunami earthquakes in Lombok in 2018 on abnormal returns and cumulative abnormal returns of insurance companies. This study used the event study approach, with three days window period after the three tsunami earthquakes from July to August 2018. The sample of this study is the stock price of 14 insurance companies listed on the Indonesia Stock Exchange. To test whether abnormal return exists, a one-sample t-test was used on the average abnormal and cumulative returns. The results show that the tsunami earthquake disasters in Lombok in 2018 have a significant effect on cumulative abnormal returns of insurance companies stocks, and this effect even bigger on the third tsunami. This finding shows that the market reacts to continuous disaster by considering the earthquake as negative information and thus decrease the stock price. This study implies that investors may buy the stocks after the disaster to get a cheaper price or hold the stocks to avoid loss.

Evaluation of the compression strength performance of fiber-reinforced polymer (FRP) and steel-reinforced laminated timber composed of small-diameter timber
Authors: Lee In-Hwan , Song Yo-Jin , Hong Soon-Il
Published: June 2021

Laminated timber composed of small-diameter timbers reinforced with a steel bar and fiber-reinforced polymer (FRP) were fabricated to satisfy the seismic design performance level of wooden columns, and their compression strength performance was evaluated. The experimental results showed that the average compression strength of the specimen reinforced with a CFRP (Carbon FRP) bar increased by approximately 7% compared to that of the control. The average compression strengths of the specimens reinforced with a GFRP (Glass FRP) bar and a steel bar increased by 38 and 37% compared to that of the control, respectively. The unreinforced control column specimens showed a diagonal failure tendency due to the fiber slope angle, and the wood part of the reinforced specimens showed a failure mode with suppressed diagonal fracture. The average strength of the column reinforced with a CFRP plate increased by approximately 6%, but the average strength of the column reinforced with a GFRP plate decreased by approximately 5%. A comparison of the measured and predicted compression strengths of the specimens showed that the strength differences of all the specimens except the specimen reinforced with a GFRP plate were good (2 to 10.4%).

Published: June 2021

The reliability of the measurement method in determining the mass concentration of wood dust relates to the sampling time for the detection of wood particles in the ambient air of woodworking places. The aim of this study was to calculate the mass limit of detection (LOD), limit of quantification (LOQ), and the minimal sampling time (tLOD and tLOQ) for determination and quantification of samples, based on the hardwood dust mass concentration at various woodworking places in the sawmills, floor production factories, and carpentries. Determination of the mass concentration of respirable, inhalable, and total hardwood dust from ambient air was performed using personal sampling pumps and three types of filter holders: respirable dust cyclone, Institute of Occupational Medicine IOM inhalable dust sampler, and total dust open-faced filter holder. The average limit of detection amounts to 0.052, 0.083, and 0.167 mg for respirable, inhalable, and total hardwood dust, respectively. The minimal detection sampling time for collecting all observed types of dust fractions ranged between 1.12 h and 1.72 h. The minimal quantification time for all collected hardwood dust samples ranged from 3.75 h to 5.51 h. Pearson’s correlation test showed that the reliability of the measurements was affected more by the dustiness of the workspace than the real sampling time.

Authors: Krzosek Slawomir , Burawska-Kupniewska Izabela , Mankowski Piotr
Published: June 2021

This paper presents research conducted on pine timber sawn from logs obtained from three different forestry regions in western Poland. Forestry regions were characterized in terms of i.e. annual mean temperature and rainfall distribution, soil, growing stock, and technical quality and type of forest. The timber logs were classified in three different quality classes, A, B, and C as per PN-D 95017 (1992). The coefficients of correlation were calculated for pairs of the studied properties (density, modulus of elasticity (MOE), and static bending strength (MOR)) considering the forestry region of origin of the different quality logs. The statistical analysis revealed that there is a strict correlation between quality class of logs, geographical origin in terms of technical quality of forest, and physical and mechanical parameters of sawn timber.
The effects of drying method on the wood permeability, wettability, treatability, and gluability of southern pine from Australia

Published: June 2021

Drying has a major impact on the viability of sawn timber production, particularly through its influence on productivity, energy usage, and product quality. Traditionally, plantation-grown southern pine structural grade timber from Australia has been dried using high temperature (≥ 180 °C) conventional batch kilns. However, the Australian industry is showing increasing interest in continuous drying kilns because of reported cost savings and potential improvements in product quality. This study investigated the differences between continuous drying and conventional drying schedules on the radial permeability, wettability, gluability, and treatability of southern pine timber from Queensland plantations. The high temperature drying resulted in significantly lower liquid permeability compared to low temperature drying; however, there were no significant differences between drying schedules for gas permeability. For combined wood surface and core data, there were no significant differences in liquid permeability between low temperature drying and continuous drying or between continuous drying and high temperature drying schedules. For earlywood after surface machining, continuous drying resulted in the greatest wettability (based on K-values), whereas for latewood after surface machining, low temperature drying produced the greatest wettability. Earlywood had greater wettability compared to latewood. Continuous drying resulted in better gluability and treatability compared to conventional drying schedules.

In order to stand out from the competition, the quality of a product as subjectively perceived by the customer is becoming increasingly important. If one wants to meet the comprehensive customer requirements, it is no longer sufficient today to develop a product that focuses only on the functional aspects, but it must also fulfil the sensory requirements at the same time. In this paper, a systematic approach is described that first describes the objectification of customer language for describing the textile haptics of automotive interior materials (11 headliners and 15 seat materials). For this purpose, ten textile-specific descriptors were developed in an expert panel. The descriptors used and the measurement of the human-haptic system are summarized in 4 main groups: 1. warmth/cold sensation, 2. friction properties, 3. deformation, 4. surface/topography. Furthermore, the human-tactile parameters (pressure, speed) that humans exert when touching textile surfaces were determined. The human-sensory product evaluation of the textiles was carried out with 116 test persons. Comparative statistical analyses of the technical parameters (e.g. roughness, friction coefficient, wetting index, deformation) and the human characteristics made it possible to create a prognosis model for determining the quality perception of textile car interior materials.

Published: June 2021

The composition of blood proteins depends on the functional state of animals, as well as on various pathologies. The goal of the work was to establish the effect of cysticercosis invasion on the protein metabolism and cellular immunity of rabbits. Rabbits were divided into two groups after visual identification of the larval cysts presence: healthy (control) and diseased (experimental). Biochemical blood tests were performed using reagent sets produced by “Filisit-Diagnostika” (Ukraine). Spontaneous cysticercosis invasion of male rabbits caused changes in protein metabolism. The content of total protein in infected animals was higher by 8.79% (P<0.05) than in control. The increase in the total protein content was due to the globulin fraction, which was 1.50 times (P<0.05) higher in affected animals than in healthy rabbits. This rise occurred as a result of a high content of γ-globulins, both in absolute value by 1.69 times (P<0.05), and in percentage by 1.51 times (P<0.05). The albumins, which are completely synthesized by liver, were lower by 10.08% (P<0.05) in rabbits with cysticercosis. The protein coefficient of experimental animals was lower by 43.89% (P<0.05) compared with the control. The concentration of uric acid in diseased rabbits was lower by 34.09% (P<0.05) than in healthy ones. We have observed a high number of T-, B-lymphocytes and T-helper cells, especially the last two indicators, which increased respectively 1.54 times (P<0.01) and 1.36 times (P<0.05) against the background of a low number of T-suppressors and O-lymphocytes — almost 5 times (P<0.001) in affected animals than in healthy rabbits. In our opinion, such changes in the proteinogram and cellular immunity indicate the intensification of immune reactions in the body of rabbits infected with the Cysticercus pisiformis as a result of inflammatory processes that occur in the liver under the action of a mechanical, toxic effect of the helminths.

Published: June 2021

This study aims to explore the ameliorative effects of L-glutamic acid (L-Glu) against carbon tetrachloride (CCl4) toxicity in male rats. Changes in the activities of alanine and aspartate aminotransferases (ALAT, ASAT) were studied in the tissues and blood of rats. Concentrations of creatinine, triacylglycerol and cholesterol were also determined in the blood of experimental animals. Intraperitoneal administration of CCl4 to rats led to changes in the blood of animals of the studied parameters — an increase of the activities of aminotransferases, triacylglycerol and cholesterol levels. At the same time, a decrease of ALAT activity was observed in the tissues of the myocardium and spleen of intoxicated animals, ASAT in their brain, and in the tissues of the lungs there was an increase in the activity of ALAT and the growth of ASAT in the tissues of the spleen In turn, with additional administration to animals intoxicated with tetrachloromethane L-Glu mitigation or no change in most of the studied indicators was observed, namely, in the blood the activity of ASAT fluctuated within the control values, and the concentrations of triacylglycerol and cholesterol did not change compared to the control. Also under the action of the studied aminoacid, no changes were detected in the activities of ALAT in lung tissue and ASAT in spleen tissue. The obtained results indicate a corrective effect of L-Glu on the physiological and biochemical parameters of rats in their intoxication with carbon tetrachloride.

The quality and safety of pork is influenced by many factors before and after slaughter. Complex of biochemical and physicochemical processes take place in the maturation of the meat. One of the key factors that affect the quality of meat from slaughtered animals is the level of cortisol in the blood, because glucocorticoid hormone is the trigger for the development of a chain of stress biochemical reactions. This paper contains results of examination of the blood concentration of cortisol and lactate and meat pH. Samples were taken in two animal groups. The first one constituted of industrially reared and slaughtered animals, and the other group consisted of animals grown and slaughtered on small farms. In the blood of industrially reared pigs in comparison with domestic animals, the concentration of cortisol is significantly higher by 39.9% (P˂0.05), as well as the level of lactate — 2.3-fold (P˂0.01). The main reason is due to the stress experienced by animals during transportation and pre-slaughter handling. There is a marked difference between the maximum and the minimum plasma level of cortisol in pigs within one group. Under stress the breakdown of glucose and glycogen in the liver and muscles took place in anaerobic condition with formation of lactate. At 1, 24 and 48 hours of pork meat maturation in case of industrial rearing and slaughtering, compared to domestic, the pH of meat was lower. Obtained results gives the possibility to suggest the lower quality of the industrially reared and slaughtered pork compared with domestic.

Evidence-based medicine is an approach to medical practice in which the decision on the appointment of therapeutic, diagnostic or preventive measures is based on the evidence of their effectiveness and safety. The objective: assessment of the effectiveness and safety of the use of NSAIDs in the treatment of chronic pelvic pain in women of reproductive age. Materials and methods. Under our supervision, there were 101 women of reproductive age with chronic pelvic pain syndrome (CPPS) on the background of chronic inflammatory processes of the pelvic organs. Patients, depending on the received treatment, were randomly divided into two groups: Group I (n=54) – complex antibiotic (AB) therapy was conducted in combination with antiplatelet agents, antihypoxants, analgesics; Group II (n=47) – complex antibiotic (AB) therapy was performed in combination with antiplatelet agents, antihypoxants and NSAIDs (DICLOSAFE, diclofenac sodium 100 mg). The exclusion criterion was the presence of an endometriosis in a patient. When patients were included in the study and 6 months after the completion of the treatment, a questionnaire was conducted to determine the severity of the pain syndrome, psychological status and quality of life. Results. Positive dynamics of quantitative and qualitative characteristics of the pain syndrome, as well as dynamics of its intensity as a result of conservative treatment for 6 months in group ІІ, was noted. Also, in group ІІ, statistically significant data on the reduction of depression and personal anxiety are noted, in contrast to the indicators of group I. The results of the questionnaire of patients in group II after treatment indicated improvement of all components of physical health. Statistically significant differences with the indicators of Group I were obtained on the scale of the effect of pain on daily activity (BP). In addition, after treatment in the II group, the patients showed statistically significant changes in mental health and all its components: vital activity (VT), social activity (SF), limitation of daily activity due to emotional problems (RE) and mental health I (MH). Conclusion. Pathogenetically grounded use of NSAIDs (DICLOSAFE suppositories) in the complex treatment of patients with CPPS allows to achieve a significant improvement in quality of life indicators due to the correction of pain syndrome. Key words: chronic pelvic pain syndrome, treatment, nonsteroidal anti-inflammatory drugs.

The objective: to find out the level of verification of endometrial hyperplastic processes (GPE) in women with uterine infertility based on the comparison of ultrasound and pathomorphological studies. Materials and methods. 64 patients of reproductive age was performed ultrasonographic study and diagnostic endometrial biopsy. Results. Three groups of GPE have been identified: polyps – 33 cases, hyperplasia –15, combination of glandular hyperplasia with endometrial polyp – 16. The endometrial polyps included: glandular – seven cases, glandular-fibrous with an advantage of the glandular component – 13, and glandular-fibrous with the advantage of the stromal component – 13. The accuracy of the verification of glandular polyps was 82%. Glandular-fibrotic polyps with an advantage of the glandular component were diagnosed in 82%. Glandular-fibrous endometrial polyps with the advantage of the stromal component were the most difficult for ultrasonic verification. The accuracy of their diagnosis was 50%. Such characteristics as nodular form, intramural position, increased echogenicity and absence of inclusions were the basis for erroneous diagnosis of uterine fibromyomas. Endometrial hyperplasia was verified at 97%. The remaining 3% were histologically diagnosed with endometrial polyposis, which were not established by ultrasound, and were considered as hyperplasia of the endometrium. Ultrasound diagnosis of the combination of endometrial hyperplasia and polyps reached 77%. The polyps on the background of endometrial hyperplasia appeared as fibromyomatous nodes. The determining role in correct diagnosis was played by hysteroscopy. Conclusion. The comparison of ultrasound data and morphological evidence suggests high accuracy of GPE detection and morphological verification. However, in some cases GPE ultrasound does not precisely determine the nature of pathological changes. Therefore, the study of the pathomorphological features of remodeling of the endometrium in the GPE remains open and requires new promising approaches. One of them, based on certain pathomorphological changes in GPE, is the use of blood flow research, in particular transvaginal color doppler, which may allow to improve the accuracy of the diagnosis of GPE. Key words: endometrial hyperplasia, endometrial polyp, endometrial hyperplasia, ultrasound diagnosis, pathomorphology, reproductive age.

In this article, data on the analysis of literature on the perinatal and maternal aspects of the domestic labor and delivery in maternity wards are conducted. For most women in developed countries, the choice of place of birth is maternity cultural norm. However, to give birth in a maternity room is a relatively recent phenomenon. In many countries, the change in birthplace has changed during the twentieth century. For example, in the UK, 80% of women were born in the 1920s, and in 2011, only 2.3%. The United States had a similar shift from 50% of births at home in 1938, to 1% in 1955. In developed countries such as Great Britain, Germany, the Netherlands, France, Italy, Israel, Canada, New Zealand, Australia, and in our geographical neighbors Latvia, Hungary and Poland have long been working on a three-step system of providing maternity care. This system includes: 1) Maternity Hospital – for women of high and moderate risk; 2) maternity centers in or near the hospitals, in which only the midwives receive births, and, if necessary, the woman and the child are quickly delivered to the hospital, where they will be in urgent assistance within a few minutes; 3) home births – for women from a low-risk group, accompanied by experienced certified midwives. The creation of a new obstetric link in Ukraine, the maternity center, is a promising direction for the development of all obstetrics. On the basis of Kyiv City Maternity Hospital № 5 a separate maternity center was created, which is an autonomous maternity ward office. The department has separate medical staff and maternity rooms as close as possible to home conditions. Emergency care for a mother and child takes several minutes. Key words: home birth, maternity center, perinatal aspects, maternal aspects.

The objective: of this study was to assess the type of temperament and stress load in women with premenstrual syndrome (PMS). Materials and methods. The research included 200 women with diagnosis of PMS who formed basic group. The control group consisted of 50 women without PMS. The type of temperament was determined by Eysenck’s Personality Inventory test. Level of psychoemotional stress was assessed by L. Reeder’s scale. Results. Sanguines predominated among healthy individuals. While among patients with PMS more than a third part was melancholic (χ2=10.01; p=0.002) and choleric persons (χ2=4.19; p=0.04) both, number of sanguines was in 3.20 times less compared to healthy persons (χ2=29.44; p<0.001). The score of neuroticism in women in basic group was significantly higher on 17.03% compared to controls (p=0.002). The highest rate was found in patients with the severe course of the disease – on 27.50% (p<0.001). The average score of psychoemotional stress in women in control group was on 10.81% higher (p=0.01) than in patients in basic one. That is mean the greater level of stress in individuals with PMS. Conclusion. The following types of temperament as melancholic and choleric predominate among women with PMS (p<0.05). The level of neuroticism is significantly increased in patients with PMS (p=0.002). High level of psycho-emotional stress, which correlated with the severity of the disease is typical for this pathology (p<0.05). The greatest indicators of stress factor were found in patients with neuropsychical, cephalic and crisis forms of PMS. Key words: premenstrual syndrome, temperament, stress level.

The objective: to present scientific justification of need of use of psychological platform when carrying out various programs the auxiliary reproductive technologies. Materials and methods. 227 women with sterility by which auxiliary reproductive technologies were shown were surveyed. To all of them psychopathologic examination by criteria of the international classification of illnesses of the 10th revision is conducted. It was thus taped that 100 women suffered boundary alienations – the main group. The control group was made by 50 fertilny mentally healthy women. To all patients full clinical-laboratory examination according to the scheme accepted in clinics of reproductive was conducted. For clarification of the reason of emergence of boundary alienations the algorithm of inspection included clinical-psychopathologic interviewing and the standard psychological tests. Results. Development of boundary alienations is promoted by combination of several factors, such as not adaptive behavior which promoted intensifying of an internal strain, dysfunction of vegetative nervous system that was shown in vegetative disturbances. Long internally the strain led to development of high level of alarm, emission corticosteriodes and further to an immunoscarce state that promoted an exacerbation of chronic somatopathies. A srategiya «flight in illness» led the koping to development of the psychosomatic diseases which main goal there was treatment avoidance. Conclusion. The above is convincing scientific justification allocation of psychological platform of auxiliary reproductive technologies – as an independent scientific problem on which quality of the decision efficiency of treatment of sterility depends. Key words: auxiliary reproductive technologies, psychological platform, scientific justification.

The problem of postpartum pyo-inflammatory diseases requires the introduction of new approaches to its solution and optimization of diagnostic and therapeutic developments. The objective: was to determine the optimal time for manual vacuum aspiration of the uterus in postpartum endometritis, correction of therapeutic tactics and control of patients in the framework of the method of fluorescence spectroscopy. Materials and methods. The main group – 170 women with postpartum pyo-inflammatory diseases, control group – 40 women with uncomplicated course of the postpartum period. Their blood serum was examined using the method of fluorescence spectroscopy, in particular after manual vacuum aspiration of the uterus. Results. Fluorescence spectra were studied for 40 women of control group and 170 women of the main group, among them in 44 (25.8%) – in the dynamics during the treatment after manual vacuum aspiration of the uterine cavity. In 93.2% of the patients in the main group after it an increase in fluorescence intensity and max displacement in the short-wave region were recorded, which was a reliable sign of improving the condition of the patients. Conclusion. The use of the method of fluorescence spectroscopy in postpartum endometritis after manual vacuum aspiration of the uterus significantly helps to improve the monitoring of the process of treatment and, if necessary, to correct it in order to recover the patients in time. Key words: endometritis, manual vacuum aspiration of the uterus, the method of fluorescence spectroscopy.

Published: June 2021

The objective: was to determine the features of the course of labor in women with a history of perinatal lesions. Materials and methods. A prospective, concurrent, controlled, randomized study was conducted involving 68 women aged 26.8 ±0.5 years, with a gestation period of 28.1 ±0.56 weeks, 41 of whom had perinatal history lesions (main group) and comparable for anthropodemographic indicators and terms of gestation of 27 women with a repeat pregnancy without abortion or unsuccessful childbirth (child death) in the history (comparison group). Results. In the anamnestic aspect, the characteristics of pregnant women with a history of perinatal losses are a relatively shorter interval between repeated pregnancies, a more frequent development of extragenital pathology - the respiratory, nervous, endocrine, cardiovascular and orthopedic disorders, and a higher incidence of gynecological anamnesis. In the context of complications of delivery, women with perinatal losses are characterized by premature birth, anomalies of labor, early discharge of amniotic fluid, ruptures of soft tissues. Conclusion. It is necessary to make a comparative analysis of the course of pregnancy, childbirth and the state of health of newborns in women with a history of obstetrical anamnesis in connection with violations of neurovegetative regulation. Key words: perinatal losses, anamnesis, childbirth, current.

The objective: to develop technique of forecasting of placental dysfunction at women with varicose illness of the bottom extremities. Materials and methods. For determination of the prognostic importance of separate indicators are analysed case histories of 155 women. The main group was made by 110 patients for whom diagnosed placental dysfunction; group of comparison – 45 patients without obstetric pathology, with the normal course of pregnancy and lack of clinical picture of placental dysfunction. We studied indicators of possible individual risk factors of development of this pathology. Were estimated 36 indicators grouped in such directions: social characteristics, reproductive anamnesis, genital and extragenital pathology. Results. Proceeding from the importance of risk factors of development of placental dysfunction it is possible to draw a conclusion about their the burdened influence on a combination to varicose illness of the bottom extremities. It is also possible to claim that existence of varicose illness of the bottom extremities at women serves as the reliable burdening factor, capable to make a systemic adverse influence on condition of hemodynamic in system vessels a mother-placenta-fetus. Conclusion. Use of an offered technique of forecasting allows to change in due time tactics of treatment-and-prophylactic actions and to reduce the frequency of obstetric and perinatal complications. Key words: placental dysfunction, varicose illness of the bottom extremities, forecasting.

Heat shock proteins are structurally highly conserved and abundantly expressed by prokaryotic and eukaryotic cells under stressful conditions. HSPs are immunodominant antigens for many microbes. They are overexpressed at sites of acute and chronic inflammation and involved in the patogenesis of various diseases. Clinical studies and results of own investigations provided evidence that HSPs and anti-HSPs antibodies can be biomarkers for the diagnosis and prognosis of reproductive disorders in women. The involvement of HSPs and anti-HSPs antibodies in pathogenesis of tubal infertility, ovarian failure, pregnancy loss is discussed. Key words: heat shock proteins, antibodies against heat shock proteins, infertility, pregnancy loss, in vitro fertilisation.

Separated spectra and operator inequalities
Authors: SABABHEH Mohammad , MORADI Hamid Reza
Published: June 2021

The main goal of this article is to show that many inequalities that are not valid in operator theory become true if we add a separation condition on the spectra. The applications include showing how monotone functions behave like operator monotone functions and how the Choi-Davis inequality becomes valid for convex functions under this separation condition.
