Published: March 2021

Most applications in engineering use a data acquisition device hooked up to a personal computer for data processing. Finding less costly, easily accessible and reliable devices will make personal computer (PC) based data acquisition systems less difficult. A soundcard may be used as such a device for it is standard in almost every PC. It can also process any voltage signal within its limits. This paper proposes a way to enable the PC to be used as an oscilloscope. A voltage signal is acquired via the soundcard LINE IN port. The maximum and minimum input signal amplitude requirements for the soundcard are established to be +1 V and –1 V respectively. Based on these findings, hardware circuitry is designed to clip any high amplitude input signals to the range of ±1 V while allowing low amplitude signals to go through to the soundcard unclipped. MATLAB is then employed to acquire, process and display the signal. The final output from MATLAB is compared with the original signal to determine accuracy of the designed oscilloscope. Analysis of the results obtained shows that the final oscilloscope designed enables the soundcard to process input signals with a high level of accuracy. The final design yields a hardware cost at a fraction of an iPod while providing an elegant user interface. This makes it suitable for college students, basement hackers and even professional engineers.

The article covers the topic Parvovirus infection in pregnant women caused the development of immunopathological reactions. 129 in fected pregnant women and 16 women with physiological pregnancy in the 1st, 2nd and 3rd trimesters were examined. In infected pregnant women, activation of the cellular level of immunity was observed, a significant increase in the number of natural killers in the peripheral blood and an increase in the immunoregulatory index were detected, with greater deviations from the control indicators found in the 1st trimester. In pregnant women, in which clinical complications were noted, the population composition of lymphocytes was characterized by an increased number of NK cells, low infection with the number of cytotoxic CD8+-lymphocytes and a shift in the ratio of CD4+/CD8+totheside, which indicates an increase in helper mechanisms. Increasing the number of T-lymphocytes, T-helpercells, NK/Т cellsandactivated CD25+-lymphocytes in pregnant women with out clinical complications at different periods of pregnancy can contribute to effective elimination of the virus and to prevent severe fetal lesions. Violation of the humoral link of the immune system in the infection of pregnant parvovirus infection was shown in an increase in the serum IgM content in different periods of pregnancy (by 79.1%, 54.2% and 38.5%), and a decrease in IgA levels in the 1st and 2nd trimesters (p>0.05), to a greater extent such changes were found in women with clinical complications of pregnancy and especially in the first trimester. Key words: pregnancy, parvovirusinfection, cellular and humoral immunity.

Published: March 2021

Maternal near miss and maternal death audit has become an esssential process in the context of obstetric care in both developed and developing countries. The objective: of the present study was to assess the quality of medical services provided within the multilevel regionalized Perinatal Health System in the Republic of Moldova, by identifying the inconsistencies with existing standards of medical care, in cases of severe obstetric complications and maternal deaths. Materials and methods. All cases of maternal near miss cases and maternal deaths recorded in the Secondary and Tertiary Perinatal Centers of the Republic of Moldova during the period 2009–2014 were analyzed retrospectively. To assess the quality of obstetric care, the following indices have been calculated: maternal near miss/ maternal deaths ratio; the mortality index for each obstetric condition/ complication. Results. During a period of 6 years, in 11 Secondary and Tertiary Perinatal Centers of the Republic of Moldova there were registered 154 651 births, 2881 cases of maternal near miss and 21 maternal deaths. The General Mortality index was 0.72%, and the Mortality Index by direct obstetric morbidity was 0.48%. 92.86% of maternal deaths through direct obstetric causes were avoidable, and the proportion of near miss cases with substandard care was 81.85%. The most frequent gaps (82.48%) were caused by human factors, such as insufficient team work, communication deficiency, lack of knowledge and clinical skills necessary to properly recognize and treat critical obstetric patients, delay and errors in diagnosis and treatment, non-compliance with clinical protocols. Conclusions. The excessively high proportion of avoidable factors highlighted in the study is alarming and implies the need for more extensive activities and the development of strategies focused on ensuring the presence of qualified medical workers in medical institutions, which will allow the provision of qualitative care and safety for patients in the Republic of Moldova, reducing maternal morbidity and mortality.

Authors: Achitaev Andrey A. , Barkhatov Konstantin A. , Udalov, Sergey N.
Published: March 2021

Currently, the use of wind power plants with magnetic speed reduction is beginning to develop in the world literature. Features of the application of these systems in combination with a wind power plant allows you to solve the issue of its interface with the electric power system. The controlled flexible connection between the turbine and the generator makes it possible to coordinate the control of the load angle of the synchronous generator. In this paper, we consider a developed controller that provides integrated control of a wind turbine with a magnetic variator with a variable pitch of the blade angle and a variable speed of rotation of the wind turbine. A promising direction for the construction of wind power systems is currently the use of electromagnetic variators as part of wind power plants. This work is devoted to the study of electric power systems that include wind turbines with electromagnetic variators. The variator is built between the wind turbine and the generator, instead of a mechanical gearbox. The high-speed change in the torque of the electromagnetic variator allows you to keep the speed of the generator. Due to the inherent non-linearity of the wind turbine and CVT, a set of operational and emergency modes was defined and then the controller was designed for each operating point. In addition, the aerodynamic torque and effective wind speed are estimated online and a planned variable schedule for the controller implementation is obtained. Was tested by simulating with MATLAB/Simulink
Percutaneous Laser Disc Decompression: In Low Back Pain or in Radicular Pain
Authors: SEÇİNTİ Kutsal Devrim
Published: March 2021

Objective: The efficacy of percutaneous laser disc decompression is still controversial due to inconsistencies between the studies. However, the reason for this discrepancy may be due to having different success levels in low back pain and leg pain. In this study, the response of both pain modalities to percutaneous laser disc decompression was examined separately.
Material and Methods: Results of 49 patients who underwent percutaneous laser disc decompression only for low back pain and 36 patients who underwent percutaneous laser disc decompression only for radicular pain were analyzed retrospectively. It was investigated on which pain type that percutaneous laser disc decompression was more effective. In addition, by examining the magnetic resonance images of the patients, it was determined whether there was a change in the size of the disc herniation.
Reults: Although statistically percutaneous laser disc decompression was effective in both types of pain, this effect was much more pronounced in the low back pain group. It was determined that percutaneous laser disc decompression did not reduce the size of the disc herniation, but still provided some reduction in radicular pain. It was determined that it was much more effective in low back without reducing the size of the disc herniation.
Conclusion: percutaneous laser disc decompression is more effective in low back pain. However, a reduction in the size of the disc herniation should not be expected.

Authors:   Sevastopol State University, P.S. Nakhimov Black Sea Higher Naval School, Sevastopol Russia, Mikhailova Alla G.
Published: March 2021

Introduction: Self-determination theory plays a crucial role in self-awareness forming. It suggests that people are motivated to grow and change as well as to be able to become self-determined by three universal psychological needs: for fulfillment of competence, connection, and autonomy. The article examines the main criteria and indicators of self-determination. Socio-pedagogical conditions are pro-posed which provide the effectiveness of the process of forming social self-determination among students. Materials and methods: the methodological basis is the ideas of personal and pro-fessional development as the basis the foundation of achieving a professional “acme” in the works of such scientists as A.S. Anisimov, A.A. Bodalev, A.A. Derkach, V.G. Zazykin, A.K. Markova, N.V. Kuzmina and others. Scientists focused on interdiscipli-nary connections and integration approaches in the study of the problems of personality self-determination. Results: recommendations are given for the design of activating methods of self-determination. The research hypothesis is based on the assumption that the for-mation of self-determination in the educational process of the university will be effective if proposed conditions are realized: providing the interconnection of formation processes and person’s self-development; inclusion of students in a variety of activities in order to acquire social experience and a system of social roles for further self-development; trainings for motivational growth and classes aimed at developing skills of self-organization and self-regulation in stressful situations. Discussion and Conclusions: according to these conclusions, a set of recommenda-tions were developed: external and internal factors of social self-determination should be considered in the system, with its inherent connection with the environ-ment, since changes in the social environment entail changes in the system of factors; in order to study personal properties, develop mutual understanding and determine ways of development and correction, one should use high-quality psychodiagnostic techniques, trainings for motivational growth, aimed at developing skills of self-organization and self-regulation in stressful situations; it is necessary to ensure the activity of students in a variety of activities.
Transformation of the institute of tourism in the consumer society in the background of the COVID-19 2020.
Authors:   Volga State University of Technology, Yoshkar-Ola, Russia, Efremova D.V.
Published: March 2021

The COVID-19 pandemic of 2019–2020 has the potential to transform the tourism industry as well as the context in which it operates. This global crisis in which travel, tourism, hospitality and events have been shut down in many parts of the world, provides an opportunity to uncover the possibilities in this historic transformative mo-ment. A critical tourism analysis of these events briefly uncovers the ways in which tourism has supported neoliberal injustices and exploitation. The COVID-19 pandemic crisis may offer a rare and invaluable opportunity to rethink and reset tourism toward a better pathway for the future. ‘Responsible’ approaches to tourism alone, however, will not offer sufficient capacity to enable such a reset. Instead, such a vision requires a community-centred tourism framework that redefines and reorients tourism based on the rights and interests of local communities and local peoples. Theoretically, such an approach includes a way tourism could be ‘socialised’ by being recentred on the public good. This is essential for tourism to be made accountable to social and ecological limits of the planet.

Published: March 2021

The Islamic revival naturally actualized the issue of Muslim education in the post-Soviet space. Moreover, its activation was facilitated by complex and contradictory processes in the religious sphere, in this context, among the followers of the Islamic faith. The growth and strengthening of the ideology of radical Islamism in the public consciousness, especially of the younger generation, the designation of the dominant following of religious precepts in everyday life as opposed to secular laws, destructive actions under the slogans of protecting the "purity" of faith made it necessary to spread religious knowledge that would not threaten the secular foundations of the Russian state. Therefore, the process of developing religious Muslim education in the territories of the historical spread of Islam has acquired special significance, because it was intended to give those who want to receive religious education such knowledge that would not preach inter-religious tolerance, and would not spread radical ideas in Russian society. Empirical data show that the surveyed population positively assesses the quality of education in a school at the mosque, with the argument that they get a good knowledge of the basics of Islam, have the opportunity to learn how to read the Holy text, as well as certain ritual actions that are quite significant for respondents in their daily lives. As well as secular education, religious education also has drawbacks and to improve the state of Islamic education, according to the interviewed expert community, it is necessary to hold Republican conferences, round tables, which will discuss the issues of improving the skills of teachers, organize training courses for teachers of maktabs, provide schools at the mosques with unified educational and methodological literature.

Published: March 2021

The article deals with the manifestation of the religious identity of the urban population of Dagestan. The obtained empirical data show the dominance of the Republican type of social identity with a large preponderance in the mass consciousness of the respondents. The author's hypothesis about the importance of religious identity for respondents was not confirmed by the results of the study, because the designation of unity with co-religionists by respondents prevails only in a subgroup of convinced believers. In addition, the awareness of community with representatives of their ethnic community is of great importance for citizens. At the same time, the study revealed contradictory behavior of citizens: for example, the study of the religious identity of the urban population indicates the prevalence of the importance of religious affiliation. In addition, empirical data shows the existence in the attitudes of citizens of the consideration of religion as an integral part of ethno-culture, which is quite natural in the observed synthesis of ethnic and religious factors in the form of ethno-confessional identity. The level of trust in various social spheres, in particular religious institutions, contributes to the formation of a positive religious identity to a certain extent. The survey data indicates a weak level of trust in co-religionists, while at the same time its high manifestation to the near radius.

Analysis of Generic IGBEM for Lifting Hydrofoils
Authors: Grm Aleksander
Published: March 2021

Today the most crucial aspect in the preliminary vessel design stage is to make it as green/blue as possible. One of the exciting goals is the minimisation of vessel resistance. The use of hydrofoils to reduce the vessel draught and consequently, reduction in the vessel resistance is today one of the hottest design topics, especially for catamaran passenger vessels. In the present work, we discuss the issues related to the implementation of Isogeometric Analysis (IGA) Boundary Element Method (BEM) for the calculation of the hydrodynamic properties of lifting hydrofoils. The use of IGBEM allows numerical calculation of foil hydrodynamic properties without the traditional step of mesh generation using the CAD geometry directly. The analysis relies on the NURBS basis function with the generic Galerkin approach allowing identical solutions procedures for 2D or 3D problems. Method accuracy and computational times for a different number of Degrees of Freedom (DOF) in 2D are investigated.

Published: March 2021

Diversely performing propellers as a consequence of design variability are nowadays a commonplace. Fundamental geometric particularities, including size, stipulate performance characteristics, which are usually the only required parameters when deciding on a propeller for specific purpose. With the main focus on the performance, accompanying phenomena, e.g. cavitation, tend to be overlooked. In this paper, propeller configurations in cavitating flow are investigated, with emphasis on real-world performance differences caused by cavitation. Recommended CFD approach is presented with respect to configuration specifics. Available experimental data is used as a baseline for a single propeller, which is then analysed in ducted and tandem configurations with resulting cavitation extents and shape evaluated in the context of current designs.

Published: March 2021

This work confers to the preparation of Lanthanum Hexa Aluminate (LHA) nanoparticles by chemical precipitation and filtration technique followed by characterization studies conducted through X-ray peak profile analysis (XPPA) and Field Emission Scanning Electron Microscopy (FESEM) supported by Energy Dispersive Spectroscopy (EDS). From the X-ray diffraction (XRD) analysis, it has been observed that the prepared powder has hexagonal crystal structure. Further, Scherrer Method (S-M), modified Williamson–Hall (W-H), and Size–Strain Plot (SSP) methods have been implemented to all LHA reflection peaks for the comprehensive crystalline analysis. The influence of crystallite size, stress, strain, and energy density values on the peak broadening of LHA nanoparticles has been critically examined and discussed in the current work. In addition to regular mathematical models this paper also provides an insight into the calculation of Youngs modulus without tedious experimental procedure. The predicted crystallite size estimated from Scherrer’s formula, and W-H models are correlated to scanning electron microscopy results and observed that the average grain size of LHA nano particles estimated from SEM analysis, and models have less deviation in the present study.

BACKGROUND Managing pain and stress during and after any surgical procedure is a real challenge and a matter of concern for both surgeons and anaesthesiologists. Various analgesics like tramadol and nalbuphine have been used as adjuncts to anaesthetic agents with different efficacy. We wanted to do a comparative assessment of efficacy between intravenous (IV) administration of tramadol and nalbuphine in managing perioperative pain and stress. METHODS This was a single blinded randomised control trial, which included 60 female adult patients in the age group of 30 - 50 years who were posted for surgical procedures like elective vaginal hysterectomy under spinal block. Patients with comorbidities like diabetes, obesity, hypertension, impaired pulmonary function, recent history of medication with selective serotonin reuptake inhibitors were excluded from the study. Study participants were divided into two groups - group tramadol (TR) and group nalbuphine (NA) with 30 patients in each group. Group TR was given tramadol 0.5 - 0.7 mg / Kg whereas group NA was given nalbuphine 0.1 - 0.2 mg / Kg after an hour of spinal block. Both drugs were administered intravenously. Midazolam 0.01 - 0.05 mg / Kg was administered intravenously within first hour of surgery for sedation. Pain, stress and sedation score, requirement of rescue analgesics and occurrence of adverse drug reactions (ADRs) over 12 hours postoperatively were compared. RESULTS Significant lowering of pain and stress scores and higher sedation score was observed in group NA in comparison to group TR. The requirement of rescue analgesic and occurrence of side effects like nausea and vomiting were less in group NA. CONCLUSIONS Intravenous administration of nalbuphine was found to be more effective in perioperative control of pain and stress and can be a better choice than intravenous tramadol.

BACKGROUND The breast tissue consists of both specialised epithelial cells and stroma. It is a site of a broad array of pathological alterations. Both benign and malignant lesions can occur in the breast. Breast cancer is the most commonly diagnosed female cancer accounting for 20 % of female malignancies globally. METHODS The study was carried out to evaluate the histopathological patterns of 589 breast lesions whose biopsied breast tissues were presented at the Pathology department of Tezpur Medical College and Hospital, Tezpur, Assam, for a period of three (03) years from January 01, 2017 to December 31, 2019. RESULTS Out of 589 cases of breast lesions, 418 were benign breast lesions (70.97 %) and 171 were malignant (29.03 %) with a benign and malignant ratio of 2.44:1. Fibroadenoma breast was the most common benign breast disease were 264 out of 418 (63.15 %) and infiltrating duct carcinoma was the commonest malignant breast lesions, in this study there were 123 out of 171 (71.93 %). Among 123 cases of infiltrating duct carcinoma, 93 (75.61 %) were grade III ;27 (21.95 %) were grade II and 03 (2.44 %) were grade I as per Nottingham histologic score system in the study group. Metastatic lymph nodes were 89 (52.05 %) were seen in the malignant cases. Early presentation (stage 0, I and II) constituted 77 (45.45 %) while late presentation (stage III and VI) accounted for 94 (54.97 %) in the breast malignancy in the study. CONCLUSIONS Histopathological study plays very important role in the diagnosis, treatment and prognosis of breast lesions. This study highlighted the distinct incidences and pathological characteristics of wide range of breast diseases and affirmed that breast cancers in developing countries like India are characterised by late presentation.

Çalışmanın amacı borsa ve makroekonomik değişkenler arasındaki ilişkinin Türkiye özelinde incelenmesidir. Çalışma gerek kullanılan yöntem gerekse veri seti anlamında benzerlerinin bazılarından ayrışmaktadır. Çalışmada bu amaç doğrultusunda makroekonomik faktör olarak kabul edilen GSYH, döviz kuru (Dolar/TL), faiz oranı ve enflasyon ile BIST100 İndeksinin getirisi arasındaki ilişki ampirik olarak analiz edilmiştir. Çalışmada kullanılan çeyreklik veri seti 2003:Ç1 ve 2018:Ç3 arasını kapsamaktadır. Yapılan analizlerde değişkenler arasındaki ilişkinin varlığının tespiti amacıyla eşbütünleşme testinin yanı sıra, bu ilişkinin yönünün belirlenmesi amacıyla nedensellik ve değişkenlerde meydana gelen şokların nereden kaynaklandığının tespiti amacıyla da varyans ayrıştırma testleri kullanılmıştır. Analizler sonucunda, BIST100 ile makroekonomik faktörler arasında trende kırılma modeline göre uzun dönemli eşbütünleşik ilişkiye ulaşılmıştır. Nedensellik analizine göre, BIST100 ile faiz oranı arasında çift yönlü ve anlamlı; BIST100’den GSYH’ye ve yanı sıra, BIST100, GSYH ve faiz oranından enflasyona, faiz oranından döviz kuruna, tek yönlü ve anlamlı nedensellik ilişkisi bulunmaktadır. Son olarak yapılan varyans ayrıştırma analizi sonuçlarına göre, çalışma kapsamında elde edilen sonuçların beklentilerle ve literatürle uyumlu olduğu görülmektedir. Buna göre, BIST100 ile faiz oranı ve döviz kurunun en güçlü uzun dönemli açıklayıcı ilişkilere sahip olduğu görülmektedir. Ulaşılan bulgular ışığında gerek yatırımcılar gerekse politika yapıcılar açısından önemli çıkarımların olduğu söylenebilir.Anahtar Kelimeler: BIST100, Makroekonomik faktörler, nedensellik, varyans ayrıştırmaJEL Sınıflandırması: C32, E44, G23

Maize is among the top three grain crops in the world. In Africa, especially Southern Africa,maize is the basic ingredient in fermented soft porridge known as Mahewu. Mahewu is a refreshing drink, produced at the household level using various practices and ingredients as a fermentation enhancer. The underprivileged consume Mahewuas the main meal of the day and hence, Mahewuisasource of dietary nutrients for many populations in Africa and South Africa. The ingredient and practices of making Mahewudiffer from one ethnic group to another. However, some of the indigenous practices are not well reported. These practices are fading away, hence, there is limited information on some indigenous practices. This paper reports some traditional practices of making MahewuinZulu-based households in Ntambanana, a rural municipality in KwaZulu-Natal, South Africa. An ethnographic research approach was adopted for the study to gain insight into the traditional practices of making Mahewu. Probing of key informants, interviews, and observations were complemented by four focus group discussions, within the range of 10-12 regular consumers of Mahewu. Four focus group discussions were conducted in Buchanana and LuwambainNtambanana; findings consistently reveal that Mahewuis popularly known as “umdokwe” and is consumed by all age groups beginning from four months to the aged. Irish potatoes (Solanum tuberosum), imbiliso, inserting a saucer, or a spoon deep down into the Mahewucontainer were mentioned and identified as fermentation enhancers which are lacking in other studies. Therefore, indigenous practices are diminishing while some practices are being lost between generations. Inadequatetransfer of these practices might make the drink, to soon be accessible only commercially. To prevent this dilemma, the retention of traditional techniques of making Mahewu with sweet potatoes could promote food and nutrition security while retaining the indigenous practices. This study reports the preparation, storage, and utilization of Mahewu, a non-alcoholic maize meal beverage in Ntambanana, South Africa. It is recommended that campaigns promoting indigenous food consumption should form part of health, social development, as well as welfare, hence, food and nutrition interventions should be implementedin rural communities.

The impacts of climate change risks, risk management mechanisms, and the physical environment under which farm households operate play significant roles in poverty and hidden hunger dynamics in developing countries. Extreme weather events are most often triggers of changes in risk management, which also affect the capacity of households to absorb the resultant shocks. This paper based on primary data collected as part of a PhD dissertation in the Department of Agricultural Economics, University of Nigeria, Nsukka, presents an analysis of farm households’ levels of vulnerability to extreme weather events in South-eastern Nigeria. A multistage sampling procedure was used in the selection of 120male-and 120 female-headed farm households that constituted the sample for the study. Both structured interview schedule and focus group discussion guide were used to gather data from the respondents, which were analyzed using UNDP vulnerability index. Using household adaptive capacity approach, data were collected on human, economic and institutional capacity of farmers in coping with extreme weather events. Female-headed households were more vulnerable than their male-headed counterparts to the effect of extreme weather events with respect to some of the indicators such as farming income, years of formal education, farm size, land ownership status, number of extension contacts, access to weather information, access to remittance, membership of cooperative and assistance from National Emergency Management Agency in the area. Overall, using household adaptive capacity approach, the results of the gender-based vulnerability analysis showed male-headed farming households with a vulnerability index of 0.38 while the female-headed farming households, on the other hand, had vulnerability index of 0.68. Although female-headed farm households were more vulnerable than their male counterparts, the farmers were all generally highly vulnerable to the incidence of natural disasters because of low adaptive capacity. The study recommends that government and development partners with the responsibility of protecting the environment should be gender-sensitive and redirect more effort in mitigating the negative agricultural effects caused by extreme weather events, especially among female-headed farm households who are more vulnerable.
