Fascinating Flesh: Revealing the Catholic Foucault
Authors: Bernauer James
Published: April 2021

The Catholic dimension in Foucault’s examination of the Church Fathers is featured because neglect of it may misrepresent the very notions of virginity and of flesh in Confessions of the Flesh. Failure to appreciate the tension between a seditious flesh and an incarnational flesh implicitly confines the Patristic vision to the limited modern field of “sexuality.” The fourth volume might be best interpreted against the background of the investigations that prompted Foucault to immerse himself in religious texts and spiritual experiences: his early writings on literature; the later interest of his lectures in pastoral technologies; and his witnessing of the political-spiritual movements both in Islam (the Iranian revolution) and in Catholicism (the anti-military protests in South America and the anti-Communism denunciations of Pope John Paul II).
What Is a Desiring Man?
Authors: Colombo Agustín
Published: April 2021

This article investigates Foucault’s account of desiring man by drawing upon History of Sexuality vol. 4, Confessions of the Flesh. In order to do so, the article focuses on Foucault’s diagnosis of the Christian elaboration of “the analytic of the subject of concupiscence” that closes Confessions of the Flesh. As the article shows, “the analytic of the subject of concupiscence” inspires Foucault’s account of desiring man. However, Foucault’s diagnosis of the Christian elaboration of “the analytic of concupiscence” proves to be debatable as it relies on a problematic interplay between Cassian’s and Saint Augustine’s account of concupiscence. The article exposes the problems that such interplay supposes by addressing the contrast between Cassian’s and Augustine’s perspective on both concupiscence and the human condition. Despite this problematic aspect of Foucault’s investigation of Christianity, the article argues that the publication of Confessions of the Flesh is central to understanding Foucault’s History of Sexuality. By providing new elements of analysis, the book reopens Foucault’s genealogical diagnosis of the formation of the medical account of sexuality and allows us to problematise new avenues for developing Foucault’s investigation in depth.
The Contribution of Profit-sharing Characteristics to the Performance of Islamic Banks
Authors: Hanafi Syafiq Mahmadah
Published: April 2021

Islamic commercial banks are highly identic with the profit-sharing as a sharia banking basic operational system. The profit-sharing becomes a specific characteristic of sharia banks as well as a distinction from conventional banks. Hence, this study aims to examine if the profit-sharing characteristic contributes to the performances of Islamic commercial banks in Indonesia. This study employed time series data derived from the Financial Service Authority (OJK) using regression-mixed test and auto-regressive heteroscedasticity (ARCH). The results pointed out that the profit-sharing system for the lending of Musharaka had an impact on the performance of sharia banks; while the profit-sharing for the funding of Mudaraba did not support the hypothesis with negative coefficient. The results suggest that the profit-sharing characteristic provides contribution to the performance of Islamic commercial banks through the lending of Musharaka. These results further indicate that the profit-sharing characteristic performed by Islamic commercial banks is proven to be effective in improving their performances. This study’s results have an implication for Islamic commercial banks to strengthen their profit-sharing characteristics and improve the public trust toward sharia banking system.

Comparison of the N-Terminal pro-Brain Natriuretic Peptide Levels, Neutrophil-to-Lymphocyte, Lymphocyte-to-Monocyte and Platelet-to-Lymphocyte Ratios Between the Patients with COVID-19 and Healthy Subjects; Are the Patients with COVID-19 Under the Risk of Cardiovascular Events?
Authors: Altınbaş Özgür , Ertaş İbrahim Halil , Mete Ayşe Özlem , Demiryürek Şeniz , Hafız Erhan , Saracaloğlu Ahmet , Demiryürek Abdullah Tuncay
Published: April 2021

Backround: The ongoing pandemic of Coronavirus Disease 2019 (COVID-19)
infection has declared as a global emergency. Although the most people
had mild illness due to the infection, some patients were seriously
affected associated with complications especially including respiratory
and cardiovascular systems. In despite of the respiratory system
involvement is in the foreground, cardiovascular complications result in
worse clinical outcomes. The purpose of this study is to compare the
levels of the N-terminal pro-brain natriuretic peptide,
neutrophil-to-lymphocyte, lymphocyte-to-monocyte and
platelet-to-lymphocyte ratios -which are accepted as a marker of
negative outcomes in cardiovascular diseases- of the patients with
COVID-19 and healthy subjects and reveal the increased risk of
cardiovascular disease in patients with COVID-19. Methods: This
prospective study was designed in a single center and included 33
patients with COVID-19 (Group 1) and 33 healthy subjects consisted of
health care professionals (Group 2). N-terminal pro-brain natriuretic
peptide levels, neutrophil-to-lymphocyte, lymphocyte-to-monocyte and
platelet-to-lymphocyte ratios were compared between the groups. Results:
N-terminal pro-brain natriuretic peptide levels,
neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios were
statistically significantly higher in the patients with COVID-19
(p<0,0001) and lymphocyte-to-monocyte ratio was statistically
significantly lower in the same group (p<0,0001). Conclusion:
Cardiovascular manifestations result in worse outcomes in patients with
COVID-19 although the disease primarily affects the respiratory system.
Early detection of this clinical situation and taking precautions have
vital importance in the progress of the disease. NT-proBNP levels,
neutrophil-to-lymphocyte, lymphocyte-to-monocyte and
platelet-to-lymphocyte ratios are inexpensive, easy, fast and
reproducible parameters that can be used in determination of probabl
cardiovascular events that may develop during COVID-19 and enables early
optimal treatment strategies for patients.
The radical and requisite openness of viable systems - implications for healthcare strategy and practice
Authors: Borghmans Felice
Published: April 2021

This paper begs an ontological question about the nature of health and
challenges some underpinning assumptions in western healthcare. In its
analysis, the structure of health, in its various statuses, is framed as
a complex adaptive system made up of dynamically interacting subsystems
that include the physiological, psychological, spiritual, social,
cultural, and more, realms. Furthermore, openness in complex systems
such as health, is necessary for the exchange of energy, information,
and resources. Yet, within healthcare much effort is invested in
constraining systems’ behaviours, whether they be systems of knowledge,
states of health, models of care, and more. This paper draws on the
complexity sciences and Levinasian philosophy to explicate the essential
role of system openness in individual and population health, and the
viability of healthcare systems. It highlights holism to be ‘not
whole-ism’, and system openness to be, not just a reality, but a
critical feature of viability. Hence requisite openness is advocated as
essential to efficacious and ethical healthcare practice and strategy,
and vital for good quality health.
Outcomes to measure the effects of pharmacological interventions for pain management for women during labour and birth: A review of systematic reviews and randomised trials
Authors: Tan Annie , Wilson Alyce N , Eghrari Donya , Clark Hannah , Tse Wai Chung , Bohren Meghan , Homer Caroline , Vogel Joshua P
Published: April 2021

Background: Pharmacological pain management options can relieve women’s
pain during labour and birth. Trials of these interventions have used a
wide variety of outcomes, complicating meaningful comparisons of their
effects. Consensus about key outcomes would facilitate the development
of a core outcome set to assess the effectiveness of labour pain
management. Objective: To identify all outcomes used in studies of
pharmacological pain management interventions during labour and birth.
Design: A review of systematic reviews and their included randomised
controlled trials was undertaken. Search Strategy: Cochrane CENTRAL was
searched to identify all Cochrane systematic reviews describing
pharmacological pain management options for labour and birth. Search
terms included “pain management”, “labour” and variants, with no
limits on year of publication or language. Selection Criteria: Cochrane
reviews and randomised controlled trials contained within these reviews
were included, provided they compared a pharmacological intervention
with other pain management options, placebo or no treatment. Data
Collection and Analysis: All outcomes reported by reviews or trials were
extracted and tabulated, with frequencies of individual outcomes
reported. Main Results: Nine Cochrane reviews and 227 unique trials were
included. In total, 148 unique outcomes were identified and categorised
into maternal, fetal, neonatal, child, health service, provider’s
perspective, or economic outcome domains. Conclusions: Outcomes of
pharmacological pain management interventions during labour and birth
vary widely between trials. The standardisation of trial outcomes would
permit more meaningful comparison between studies. Funding: No external
funding was provided. Keywords: Labour and birth; pain management;
pharmacological interventions; systematic review
TRENDS OF COMMUNITY-BASED INTERVENTIONS ON SUSTAINABLE WATERSHED DEVELOPMENT IN THE ETHIOPIAN HIGHLANDS, THE GUMARA WATERSHED
Authors: Addissie Meseret , Molla Gashaw
Published: April 2021

Soil erosion is the driver of food insecurity and environmental
degradation affecting the lives of smallholder farmers. To tackle soil
and water degradation government-led large-scale soil and water
management programs have been introduced at a watershed scale. The
long-term viability of those practices in the Gumara watershed remains a
major challenge. The objective of the study was to better understand the
general approaches used to implement and design watershed management
practices so that soil and nutrient transport to downstream water bodies
could be managed. Sub watersheds from the large Gumara watershed were
identified for detailed study based on erosion hotspots using the SWAT
model. These sub-watersheds represent communities organized for
conservation works in the absence of food assistance programs. The data
were collected from four focus groups of fifty participants each, field
observation, and desk-level meetings with experts. A structured
questionnaire was used to get relevant information to the participating
farmers. According to the findings, each of the selected watersheds used
similar approaches to implement conservation activities. The community
withdrew from conservation efforts, even on their farm fields, since the
success rate was below the expectation. At this spot realizing the
long-term benefits of watershed development activities stayed
challenging. The smallholder farmer, on the other hand, clearly relies
on rain-fed agriculture and hopes to see immediate results to feed his
family. In conclusion, government-led development programs have not been
evaluated, technically supported, lack trusted in the community and
hence development efforts were put in jeopardy.

Assessing Changes in Clusters of Wildlife Road Mortalities after the Construction Wildlife Mitigation Structures
Authors: Yamashita Thomas , Livinigston Trinity , Ryer Kevin , Young John , Kline Richard
Published: April 2021

Collisions with vehicles are a major threat to wildlife populations and
often occur in identifiable patterns. To reduce wildlife road
mortalities, mitigation structures including exclusionary fencing and
wildlife crossings are constructed. Openings in fencing at road
intersections may lead to concentration of road mortality hot spots at
openings leading to a belief that these gaps concentrate road
mortalities. However, it is also possible that hot spots existed at
these locations before construction indicating that road mortality
patterns have not changed with mitigation structure construction.
Therefore, to assess mitigation structure effectiveness, it is important
to examine both road mortality numbers and road mortality spatial
distribution. Wildlife road mortality data was collected on a 15-km
section of rural highway in Texas, USA before, during, and after the
construction of wildlife mitigation structures. We expected that the
number of road mortalities would decrease after construction compared to
before construction and that road mortalities would become more
concentrated around openings in the fence. We used ANOVA to compare
numbers of road mortalities and emerging hot spot analysis and
generalized linear modelling to assess changes in road mortality spatial
distribution. Road mortalities were not significantly different in the
before and after construction periods (p = 0.092). While there were no
significant changes in road mortality patterns with construction,
cluster intensity was greater when nearer to fence openings in all three
time periods. Emerging hot spot analysis provides an effective and easy
way to visualize road mortality patterns through time, however, due to
low numbers of mortalities in many road mortality studies, including
this one, the power of this analysis to detect significant changes in
road mortality may be limited. This technique can provide both
ecologists and transportation planners an effective tool for identifying
patterns that may warrant further investigation using traditional
statistical techniques.
Study of postvaccinal immunity to whooping cough in children with connective tissue dyslasia syndrome
Authors: Bezrodnova S. M. , Demurcheva I. V. , Kravchenko O. O.
Published: April 2021

Purpose: to evaluate the effectiveness of post-vaccination immunity against whooping cough in children aged 1 to 17 years with connective tissue dysplasia syndrome in Stavropol.

The principal component analysis was used to optimize the interpretation of immunograms in connective tissue dysplasia syndromedepending on protective titers for whooping cough. Analysis by the method of principal components showed that the links of cellular immunity predominate in children with connective tissue dysplasia syndrome with low titers of antibodies to whooping cough.The general variant of the response of the immune system was observed in children with protective titers of antibodies to whooping cough (1: 160—1: 320). In children with connective tissue dysplasia with titres of 1: 640or more antibodies to whooping cough, humoral and cellular immunities are closely interrelated, it is the presence of humoral and cellular immunity that makesit possible to develop a stable immunity to preventable infections.

Thus, the method of main components effectively provides accessible information on key immune processes and is promising.

Authors: Kiselevich O. K. , Zubova E. D. , Takhtokhodzhaeva G. R. , Yusubova A. N.
Published: April 2021

The variety of clinical manifestations and the absence of strictly specific features make tuberculosis and toxocariasis difficult to diagnose and treat. Doctors of various specialties are engaged in the diagnosis of toxocariasis, depending on which organ system is affected in a person and with whatsymptoms he turned to a medical institution.

Purpose: to describe the case of detecting toxocariasis in a child who was treated in a tuberculosis hospital from a bacillary family contact with pronounced indicators of immunological tests and revealed changes during CT scan of the chest organs.

A complex differential diagnostic path and constant medical supervision made it possible to establish a rather rare disease - toxocariasis in a child from family contact with a patient with tuberculosis.

Conclusion. In the differential diagnostic series in patients withtuberculosis, the presence of parasitic diseases with a similar clinical and radiological picture cannot be excluded.

This analysis will unfold in the definition of environmental responsibility in the Brazilian law and forms of civil damages the environment. It will be observed that the environmental compensation has the distinct nature of civil damages, each institute applied due to pipelining by facts that have no connection. Through deductive methodology with theoretical and documentary research, verify that the rules of substantive law adequately serve the purpose of civil remedies and do not have the same purpose of environmental compensation. However, it is still addressed the deficiency of judicial protection due to the lack of specific procedures and consistent to environmental protection, especially in relation to the liquidation of environmental damage.
As presidências portuguesas do Conselho da União Europeia: promovendo a "Europa global" em busca de relevância internacional
Authors:   Universidade do Minho, Ferreira-Pereira Laura C.
Published: April 2021

This article examines the legacy of the three Portuguese Presidencies of the Council of the European Union (1992, 2000 and 2007) in the framework of the Common Foreign and Security Policy (CFSP) and European Security and Defence Policy (ESDP). It places particular emphasis on the efforts undertaken by the national authorities to promote the EU’s global actorness as part of a strategy aimed at enhancing the country’s European credentials and international relevance. The study confirms the incremental prioritization of the CFSP/ESDP-related issues in the Portuguese EU presidencies’ agendas while concluding that, as a result of such tendency, one has witnessed the growing projection of Portugal’s vision of the European foreign policy.
Portugal como Estado-Pivô ecuménico da União Europeia: O caso das cimeiras internacionais nas presidências portuguesas
Authors:   IPRI-NOVA, Mendes Pedro Emanuel
Published: April 2021

This article develops an analysis of the impact of the historical ecumenical pattern of portuguese foreign policy on the European Union’s external relations. Its main objective is to identify Portugal’s influence on developing the European Union’s (eu) external relations, namely the holding of international summits in the framework of the portuguese eu presidencies. The article is structured in two main parts. First, the article theorises Portugal’s role as a Pivot State in the eu’s external relations, underlining Portugal’s current foreign policy’s identity and normative characteristics. Secondly, the article presents an analysis of Portugal’s role in the organisation of international summits. Its central argument concerns the explanation of Portugal’s contribution to the eu in terms of European foreign policy, namely in the sophistication of the eu’s external relations and its international image.
How Peculiar Are South Korean OFDI to Russia?
Authors: Sutyrin S. F. , Korgun I. A.
Published: April 2021

This paper investigates nature of the Korean OFDI in the middle-income countries during the period 20122019. The goal is to identify any common features or differences with the observed structure of the Korean OFDI in Russia. The study is based on an assumption that a country’s investment strategies are determined by businesses. In general, business makes investment decisions based on the priorities for resource optimization and profit maximization on a global scale. Under this approach, investments to Russia would be a part of a more global strategy of Korean firms. Also, authors discuss prospects for the Russia-Korea investment cooperation under the US sanctions and how ongoing structural changes in the global economy can influence investment decisions of Korean companies.

Obtained results suggest that during the period under investigation, structure of the Korean investment in Russia was similar to the structure observed in other middle-income countries. There are clear signs that investments were motivated by gaining access to the market (in other words, they were market-seeking by nature). In the near-term increase in Korean investments to Russia is unlikely due to global recession triggered by Covid-19 pandemic and risks of harder US sanctions.
The Split in Boko Haram and Its Impact for the Lake Chad Basin Region
Authors: Denisova T. S. , Kostelyanets S. V.
Published: April 2021

The Islamist group Boko Haram (BH) was founded in the early 2000s and in less than two decades has transformed from a “Nigerian” movement into a regional one. Tactical, strategic and ideological differences between the leaders of BH have repeatedly led to its splits into separate factions; the most serious occurred in 2016, when the group split into the Islamic State in West Africa Province and Jamaatu Ahl-is-Sunna Lidda’Awati Wal-Jihad, the latter being still referred to as “Boko Haram” for convenience.

The present paper examines the reasons for the splits in BH, the goals and military tactics of the two factions, and the prospects for the development of the security situation in the region of the Lake Chad basin (LCB), where armed conflict is fueled by large-scale poverty, socio-economic and political marginalization, and ineffectiveness of local authorities against the background of intertribal tensions and massive migration.

The LCB has now become a huge human reservoir for jihadist recruitment. The situation in the region is further complicated by the fact that a significant portion of the population supports the Islamists, while the majority of locals are targeted by them and seek to leave their homes.

The authors note that the division of BH into separate factions has made it more difficult for the LCB armed forces to conduct anti-terrorist operations, and for the LCB governments to negotiate cease fires or retrieve hostages, although, simultaneously, the split has led to a certain decline in the level of violence and to the weakening of the influence of the Islamists on the socio-economic development in the region.
Image Transformation of Frederick Chiluba, Ex-President of Zambia (Attitude to Former Presidents in African Countries)
Authors: Prokopenko L. Ya.
Published: April 2021

The article analyzes the transformation of the political image of Frederick Chiluba, President of the Republic of Zambia in 1991-2001. As a representative of a new formation of African leaders in the era of the continent’s transition from authoritarianism to political pluralism, he was an ambiguous figure. His role in the return of the multi-party system in the country and in the liberalization of the national economy is discussed. It is stressed that within the framework of the existing political culture this politician was not immune to inevitable mistakes. However, the style and methods of Chilubas leadership (persecution of his predecessor, manipulation using the ethnic factor in order to retain power, ignoring criticism of the opposition and allies) periodically led to tension in the internal situation in the country and negatively affected his political image and the image of the government in general.

In 1990-2000s the negative impact of tensions between Zambian politicians who held the presidency at different times on the stability of the country was clearly manifested. The persecution of ex-President Chiluba charged with corruption demonstrated the authorities’ policy to combat this social evil, but it was ambiguously perceived and interpreted by the society and by analysts. It is noted that for all the mistakes and shortcomings of Chilubas ten-year rule, it is necessary to recognize his merits in creating the economic base of Zambia and in proclaiming it a Christian country, which was practically forgotten after his death.

The article shows the gradual rehabilitation of Chilubas memory, in which all living ex-presidents and the current Head of State take part. The experience of Zambia shows that under African realities, former presidents enjoy honors and certain privileges, provided they do not participate actively in politics and do not enter into open conflicts with their successors.
Direct Investment Exports and Emigration: The Experience of Modern India
Authors: Volodin A. G.
Published: April 2021

The article uses the example of independent India to study the correlation of investment and migration flows to foreign countries. It is shown that Indian investment flows, whose origins date back to the first half of the 1960s, were particularly active outside, mainly in industrialized countries, after the economic reform of 1991. The main interests and activities of Indian TNCs and their methods of work abroad are demonstrated. The possibilities of foreign activities of Indian investors in the new conditions of the coronavirus pandemic were evaluated. The central directions of investment flows and Indian foreign migration (USA, England, West Asia, etc.) are fundamentally the same. Adaptation of Indian immigrants is more successful in the countries where the English language is spoken. The problem of possible Indian migration to Russia is highlighted as a separate topic. Its potential positive and negative consequences for the economy and politics of the Russian Federation are outlined.

Three-dimensional integral dry friction model for the motion of a rectangular body
Authors: Salimov M. S. , Merkuriev I. V.
Published: April 2021

Introduction. A three-dimensional dry friction model in the interaction of a rectangular body and a horizontal rough surface is considered. It is assumed that there is no separation of the body from the horizontal surface. The body motion occurs under the conditions of combined dynamics when, in addition to the longitudinal movement, the body participates in twisting.

Materials and Methods. Linear fractional Pade approximations are proposed, which replaced the cumbersome analytical expressions that most accurately describe the motion of bodies on rough surfaces. New mathematical models describing sliding and twisting of bodies with a rectangular base are proposed.

Results. Analytical expressions of the principal vector and moment of friction for rectangular contact areas are developed and scientifically established. A friction model that takes into account the relationship between sliding and twisting speeds, which provides finding solutions for Pade dependences, is developed. After numerical solution to the equations of motion, the dependences of the sliding speed and angular velocity on time were obtained and constructed. Graphs of the dependences of the friction forces and their moment on two parameters (angular velocity and slip velocity) were constructed, which enabled to compare the integral and normalized models of friction. The comparison results showed good agreement of the integral model and the model based on Pade approximations.

Discussion and Conclusions. The results obtained provide considering the dynamic coupling of components, which determines the force interaction of a rectangular body and a horizontal surface. These results can be used in mobile robotics. The analyzed motion of the body occurs through the motion control of a material point inside the body. Such mobile robots can be used when solving a wide class of problems: when creating autonomous robots for the exploration of outer space and planets; in the diagnosis and treatment in case of passing through complex structures of veins and arteries; in research under water, in places of large differential temperature; in underground operations.
Consumable electrode – additional filler wire arc interaction control under surfacing (DE-GMAW)
Authors: Poloskov S. S. , Erofeev V. A. , Sholokhov M. A.
Published: April 2021

Introduction. Arc surfacing through feeding an additional filler wire heated by an additional arc burning between the filler wire and the electrode wire is considered. Under the conditions of such surfacing, the minimization of the input of the remelted substrate metal into the weld metal is studied. The research objectives are to examine the conditions providing self-regulation of this advanced arc surfacing process, and to evaluate control capabilities of the heat impact power on the metal and on the weld metal flow.

Materials and Methods. In solving a wide range of welding and surfacing tasks, it is advisable to use engineering analysis methods based on physicomathematical modeling of processes and phenomena. These include:

self-regulation of the arc process under joint melting of the electrode and the filler wires;
assessment of the possibilities to control the heat impact power on the metal and on the weld metal flow during the formation of the weld The features of the arc surfacing of anticorrosive chromium-nickel steels on low-alloy steel are considered in the paper.
Results. New mathematical dependences are proposed that describe physical phenomena under surfacing with an arc interaction between the electrode and filler wire. A physicomathematical model of the joint melting of the electrode and filler wire is developed. It provides determining the values of the control parameters. In addition, you can find out how much heat affects the substrate from:

heat release in the main arc,
droplet flows of the weld electrode and filler metal,
arc plasma
Discussion and Conclusions. It is established how the current and the lengths of the main and additional arcs are affected by the supply voltages. The feed rate of the electrode and filler wire with a diameter of 1.6 mm and 1.2 mm made of Inconel 625 alloy is determined. It is shown what thermal effect the substrate undergoes in this case. It is noted that due to the larger value of the main arc current, the diameter of the electrode wire should be larger than that of the filler wire. The heat flow in the substrate is created mainly by the flow of the weld metal droplets.
On the modification of bit-flipping decoder of LDPC-codes
Authors: Gurskiy S. S. , Mogilevskaya N. S.
Published: April 2021

Introduction. In all types of digital communication, error control coding techniques are used. Many digital communication standards, such as Wi-Fi and 5G, use low density parity check (LDPC) codes. These codes are popular because they provide building encoders and decoders with low computational complexity. This work objective is to increase the error correcting capability of the well-known bit-flipping decoder (BF) of LDPC-codes. For this purpose, a modification of the decoder is built, which enables to dynamically control one of its main parameters whose choice affects significantly the quality of decoding.

Materials and Methods. The well-known bit-flipping decoder of binary LDPC-codes is considered. This decoder has several parameters that are not rigidly bound with the code parameters. The dependence of the decoding quality on the selection of the output parameters of the bit-flipping decoder was investigated through simulation modeling. It is shown that the decoding results in this case are significantly affected by the input parameter of the decoder — threshold T. A modification of the BF-decoder of binary LDPC-codes has been developed, in which it is proposed to set the threshold dynamically during the execution of the algorithm depending on the error rate. A comparative analysis of the error- correcting capability of decoders is carried out by the simulation modeling method.

Results. A lemma on the maximum value of the decoder threshold T is formulated and proved. Upper bounds for the number of operations are found for the original and modified decoders. A simulation model that implements a digital noise-immune communication channel has been built. In the model, the initial data is encoded with a given LDPC-code, then it is made noisy by additive uniformly distributed errors, and thereafter, it is decoded in turn by the bit-flipping algorithm with different threshold T parameters, as well as by a modified decoder. Based on the input and output data, the correction capacity of the decoders used is estimated. Experiments have shown that the error-correcting capability of the modified decoder in the range of the real error rate is higher than that of the original decoder, regardless of the selection of its parameters.

Discussion and Conclusions. The lemma, proved in the paper, sets the upper bound on the threshold value in the original decoder, which simplifies its adjustment. The developed modification of the decoder has a better error- correcting capability compared to the original decoder. Nevertheless, the complexity of the modification is slightly increased compared to the original algorithm. It has been pointed out that the decoding quality of a modified decoder develops with a decrease in the number of cycles in the Tanner graph and an increase in the length of the code.

The work is devoted to clarifying the equilibrium state of the V-belt element in the grooves of pulleys. Refined formulas for determining the axial forces in the grooves of pulleys are obtained. Experimental studies were carried out using special load cells that allowed for the axial forces to count the normal pressure N(α) on the working faces of the pulley grooves. In parallel with the determination of axial forces, sliding curves for various belt sizes are obtained. Regularities of the distribution of axial forces along the arc of the girth of the corresponding pulley are established. Conclusions are obtained that determine the performance of V-belt transmissions.

Published: April 2021

This article is devoted to the most important issue of ensuring an innovative breakthrough in socio-economic development in the conditions of information and economic confrontation. Today, humanity is entering an era of a fundamentally different system of social relations, values and meanings. The emergence of a multipolar world model increases the competition of developed countries, on the one hand, and weakens the role of the state in society, on the other. Economic sanctions significantly hinder innovative development, so the state, as one of the main social institutions, still needs qualitatively new, more productive, innovative solutions, the emergence and implementation of which is impossible without appropriate personnel: researchers, analysts, developers, managers and workers.

An increase in the incidence and mortality of the population from pathologies associated with the formation of the pathobiome as a stable community of microorganisms occurs simultaneously with an increase in the proportion of antibiotic-resistant microorganisms in these communities. The formation of a pathobiome inevitably leads to the development of an immunodeficiency state and an increase in sensitivity to viral infections. The paper describes the stages of pathobiome formation and its main characteristics. Approaches have been formulated to prevent its pathobiome formation or reduce its stability, ensuring the effectiveness of correction. Experimental studies of pathobiome formation are described.
