Features of the Formation of the Evolutionary Trajectory of Agricultural Land Use System
Authors: Mykhaylov A.M. , Makarova V.V.
Published: March 2021

The article deals with the analysis of scientific developments in the structuring of systems, in particular land use systems. Based on the results of foreign and domestic scientists studied the position of ecological and economic structuring of the agricultural land use system in the trajectories of energy and information transformations that occur during a certain historical time within the specified space. Many factors that have the greatest influence on the organization of order in the system were considered, the list of which includes not only material objects, but also such objects of intangible nature as information, knowledge, limitations, relationships, etc. It is determined that the trajectory of the system means the line of its life history as a direction, phenomenon, sequence of any development of the system in space and time with any changes in the external environment. Further development of the trajectory of the land use system involves the transformation of environmental knowledge into economic (preserved land and natural potential). It is substantiated that the order in the land use system is possible only with the appropriate state support. Modern land use is characterized by undesirable economic and environmental transformations. In the conditions of degradation of the fertile soil layer, reduction of investments, wear and tear of technical equipment and lack of effective environmental policy, land users do not have motivational levers to carry out economic activities within the established environmental standards. The strategy of systemic behavior of the subjects of land relations should change more actively than there are negative changes in the subsystems and individual elements of the integrated system of land use. From the above positions, the structuring of the agricultural land use system should contribute to the processes of preservation and restoration of quality properties of agricultural lands and reproduction of productive potential of lands.

The objective of the study: to determine the place and effectiveness of video-assisted thoracoscopic lung resection (VATS resections) in the differential diagnostic procedure for examination of patients with chest diseases.

Subjects and methods. In 2017-2019, 1,190 patients with suspected respiratory tuberculosis were examined in the differential diagnostic department of TB Dispensary, the Ministry of Health of the Kabardino-Balkarian Republic; 106 (8.9%) needed VATS since it was impossible to verify their diagnosis despite various biopsies. The age of 106 patients varied from 18 to 80 years old, there were 66 men (62.0%), and 40 women (38.0%). The preoperative diagnosis was as follows: single or multiple lung lesions – 83 (76.9%) cases, disseminated lung disease of unknown etiology or interstitial lung disease of unspecified etiology – 25 (23.1%) cases.

In all cases, the surgical specimens were sent for comprehensive tests, including histological tests, microbiological tests (fluorescent microscopy with Ziehl-Nielsen staining, culture for Mycobacterium tuberculosis (MTB) by Bactec, and culture for secondary flora and fungi), and molecular genetic tests to detect MTB DNA.

Results. The diagnostic efficiency when using VATS resections, histological and microbiological testing of surgical specimens made 98.1% (95% CI 93.38-99.48; Wilson's method). Among the diagnosed diseases, pulmonary tuberculosis was confirmed in 47/106 (44.3%) patients, cancer – 37/106 (34.9%), the rest of patients were diagnosed with some other disorders including orphan diseases.

Authors: Żądło Tomasz
Published: March 2021

The problem of the estimation of the design-variance and the design-MSE of different estimators and predictors is considered. Bootstrap algorithms applicable to complex sampling designs are used. A generalisation of the bootstrap procedure studied by Quatember (2014) is proposed. In most of the cases considered in our simulation study it leads to more accurate estimates (or to very similar ones in remaining cases) of the design-MSE and the design-variance compared with the original algorithm and its other counteparts.
Representations of Maghrebians' Immigrant Life in France in Two Literary Generations: A Multilevel Cognitive Stylistic Reading of Driss Chraibi’s Les boucs and Azouz Begag’s Le gone du Chaaba
Authors: Majhad Khalid
Published: March 2021

While political analysts, economists, cultural studies scholars have all been offering insightful analyses of the different matters relating to immigrant life in different parts of the world, this article reaches for a first-hand testimony in two autobiographical novels by two internationally recognized Maghrebian novelists who respectively represent the first and second generations of Maghrebian immigrants in France. In a rather innovative manner, the portrayal of immigrant life in the two novels is analyzed from a cognitive stylistic perspective, and informed by the author’s multiple research viewpoints, those of a Maghrebian literature critic, a francophone postcolonial studies researcher and a frequent visitor to France carrying the concerns of an extended family based there. The interest in style during our close reading of these largely autobiographical narratives is based on the assumption that an author's style is a reflection of their attitude and worldview. Chraibi’s novel Les Boucs (1955) is as timely now as it was in the day of its first appearance for its balanced and largely objective analysis of the sociological, psychological and economic conditions of North African immigrants. Stylistically, Les boucs features a close correlation between its form and content in that the chaotic nature of immigrant life is formally embodied in Chraibi's non-linear mode of writing. In contrast to the bleak picture presented throughout Chraibi's text, Begag's convivial approach oozes hope for his readers who come to realize the futility of continuing to curse the state of deprivation and inequity while there can always be ways setbacks can be turned into opportunities. The study uses a qualitative method of stylistic analysis and applies the two necessary principles of 'contextualization' and 'comprehensiveness' to ensure a high degree of analytical and interpretive validity.

Authors: Skryabin K.G. , Kamionskaya A.M.
Published: March 2021

This study analyzes the current regulatory system for genetic engineering in Russia in terms of expected amendments related to genome editing technology, given that its products - genome-edited crops - have already appeared on the international market. A list of corresponding concepts that require legal rethinking and definition has been compiled. Changes in the model of state regulation of genetic technologies in Russia are proposed: the transition from a process-oriented regulation system to a risk-based system. To assess the risk of public rejection of the products of genetic technology and new biotechnologies, 931 participants of the opinion poll have been selected who underwent an online sociological survey using purposive sample techniques. The obtained results revealed the innovation potential of the Russian society and experts in the novel genetic and digital technologies in agriculture, their attitude to the threat of global hunger and the application of biodegradable materials and biofuels in relation to the circular economy.

The review examines various parties of oxygen-dependent human adaptation to microgravity belonging to different levels of the integral system organization. Particular emphasis has been placed on the cellular sensing systems of immediate and chronic reactions to altered O2 delivery. The authors expound the key oxygen sensors and heterogeneity of the sensing mechanisms. They also concern themselves with the role of O2 active forms and O2-sensing elements developing in the spaceflight environment. The first post-flight evidence of an increase in frequency of oxidation post-translational modifications in proteins suggests a hypothesis about the direction and systemic mechanisms of oxygen-dependent adaptation of the human organism to in microgravity.

Protection of personnel health is part and parcel of the corporate social policy adopted by oil producing companies with the divisional structure. The medical care system using outsourcing needs a proficient control of its functioning. Since it incorporates dozens of objects, the control is workable only provided digital technologies are applied. We made choice of the infographic matrix to build up two matrices, i.e. one for health risk management and the other, for resources and processes management. Besides, we developed systems for quantitative risk evaluation, and to score key resources, processes, and medical personnel efficiency on 5-point scales. Weight coefficient was accepted for each factor. The technique has been implemented for health analysis and healthcare evaluation at 49 enterprises. Scrupulous attention was given to the enterprises within the orange zone (51-75 on the scale). Out of 9 to 10 enterprises that traveled in the zone over 3 years of monitoring, 4 were present in both matrices. Analysis of the reports provided guides to develop response measures suitable for specific enterprises. Health risk matrices can find application in a large number of enterprises for online information acquisition, problem identification and solving.

Exploring Spike Protein as Potential Target of Novel Coronavirus and to Inhibit the Viability Utilizing Natural Agents
Authors: Nandi Sisir , Roy Harekrishna , Gummadi Asha , Saxena Anil K.
Published: March 2021

Background:

By the end of 2019, the sudden outbreak of the novel coronavirus disease
(COVID-19) has become a global threat. It is called COVID-19 because it was caused by the novel
coronavirus (SARS-COV-2) in 2019. A total of 1.9 M deaths and 87.9 M cases have been reported
all over the world, where 49M cases have recovered so far. Scientists are working hard to find chemotherapeutics
and vaccines for COVID-19. Mutations in SARS-CoV-2 have been observed in a
combination of several hazardous stresses, making them more resistant and beneficial. So to break
down the viral system, the disease targets are examined.

Objective:

In today's review, a comprehensive study of spike protein explains the main purpose of
the novel coronavirus and how to prevent the spread of the disease virus cross-transmission from infected
to a healthy person.

Methods:

Covid-19 has already been declared a pandemic by the World Health Organization
(WHO) due to its result in causing death and severe illness globally. SARS-CoV-2 is highly contagious;
however, the intermediate host of the novel coronavirus is not clear. To explore the mechanisms
of disease, one of the viral targets, such as the spike protein that binds to human cells and
causes the disease by altering its genetic structure which is considered along with potential inhibitors.

Results:

It has been shown that the interaction of receptor-binding domain (RBD) protein of
SARS- CoV-2 spike and the angiotensin-converting enzyme 2 (ACE2) host receptor and further replication
of coronavirus spike protein causes its invasion in the host cell. The human Lymphocyte
antigen 6 complex, Locus E (LY6E), inhibits the entry of CoV into host cells by interfering with
the human gene, inducing spike protein-mediated membrane fusion. Some natural formulations
have also been shown to prevent spike protein from binding to the host cell.

Conclusion:

With the development of the LY6E gene activator that can inhibit spike protein-
ACE2-mediated membrane fusion, new opportunities for SARS-CoV-2 treatment may
emerge. Existing antiviral fusion inhibitors and natural compounds targeting spike resistance can
serve as a template for further SARS-CoV-2 drug formulation.

Published: March 2021

Objective:

Synthesis of magnetic nano Iron oxide (Fe3O4) ferrofluid nanoparticles using chemical methods and its characterization studies

Method:

Iron oxide (Fe3O4) ferrofluid nanoparticles is synthesized by using the chemical co-precipitation technique, ferric and ferrous salts in the alkaline medium, which is known as Reimer’s procedure.

Results:

Nano iron oxide (Fe3O4) particles have different magnetic properties and different magnetic moments, differentiating macroscopic iron oxide in suspended particles. The ratio of surface to volume increases along with the decrease in atomic size so that the surface properties are essential for using any nano-material. Prepared Fe3O4 nanoparticles were coated with oleic acid (C18H34O2) and polyvinyl butyral((C8H14O2)n), further characterized by Materials characterization techniques (SEM, XRD and FTIR). Magneto-rheological (MR) fluid has been one of the interesting studies the shear stress of PVB coated nano iron with microsphere has approximately the same as of PVB coated nano iron but shows very high shear stress withstanding capacity at 650 s-1 shear rates.

Conclusion:

The permanence of the magnetic colloidal depends on the thermal contribution and the balance between attractive and repulsive interactions.
Significance of Color Spaces and Their Selection for Image Processing:
A Survey
Authors: Ansari Mohd. Aquib , Singh Dushyant Kumar
Published: March 2021

:

The human visual system is encompassed with three components that help to produce a color sensation. The color display devices use this concept and create their full range of colors by incorporating all three primary color components. Any displayable color can be created with the help of these primaries. This paper comprises the concept of color space, which helps to understand a particular device’s color proficiencies. Since colors are a more robust descriptor, color spaces are considered to play a significant role in representing an image appropriately. The performance of many algorithms depends on the selection of an appropriate color space. There are many kinds of color spaces that can be used in real-time applications. These are RGB, nRGB, HSV, TSL, YCbCr, YUV, YES, CIE-XYZ, CMYK, etc. In this paper, color spaces and their vast classification are described in brief. Apart from these, the characteristics, applicability, limitations, mathematical conversion, and other essential factors are also explained for each color space.
New Perspectives for SARS-CoV-2 Rapid Detection
Authors: Khattabi Latifa , Bouhenna Mustapha Mounir , Sellam Feriel
Published: March 2021

:

The present paper elucidates the conceivable application of two key molecules in
SARS-CoV-2 detection of suspected infected persons. These molecules were selected on the basis
of the strong interaction between ACE-2 and S protein that allows virus attachment to its host
cells; on the other hand, specific immunocompetant effectors are generated by the human immune
system during the infection. Several testing procedures are already being used to diagnose SARSCoV-
2 infection, particularly the RT-PCR technique. ELISA and LFIA are possible assays for the
employment of shACE-2/ hAc-anti-S (the molecules of interest) as the main agents of the test that
confer dual principal functions (capture and detection). The future diagnostic kits involving
shACE-2 and hAc-anti-S will possibly be highly sensitive with rapid detection in addition to their
advantage of relatively easy conception. They could be largely considered as technically advanced
kits in regards to the current SARS-CoV-2 diagnostic immunoassays.
Effects of coconut oil on Alzheimer disease
Authors:   Department of Anatomy, College of Medicine, King Saud University, Riyadh, Saudi Arabia, Al-Matrafi Tahani Ahmad
Published: March 2021

Dementia is a general term for loss of memory, language, problem-solving, and other thinking abilities that are severe enough to interfere with daily life. Alzheimer's disease (AD) is the most common cause of dementia. Risk factors as age, genetics, environment, lifestyle, and metabolic disease. The etiology of AD remains not fully explained, but both genetic and environmental risk factors have been proposed to be involved. Microscopically, intraneuronal neurofibrillary tangles (NFTs) and extracellular senile plaques characterize the AD. The amyloid cascade hypothesis (ACH) suggests that the imbalance between the Amyloid-β generation and its clearance causes dysfunction and consequently cell death. Coconut oil may represent a cheap and natural treatment for AD. This is because coconut oil contains medium-chain triglycerides (MCTs), which are digested to ketones in the liver that are linked to mitochondrial function enhancement and oxidation-reduction. Recent studies have investigated the possibility of using trans-zeatin and phytoestrogen and other sex hormones like substances present in coconut water and a young coconut juice (YCJ) in reducing the chance of AD. Coconut is known as a 'functional food' that is extremely nutritious. Virgin coconut oil (VCO) differs from ordinary coconut oil as the former contains a lot more biologically active components. Phenolic compounds and hormones contained in coconut can help prevent amyloid b peptide aggregation, potentially inhibiting a key step in the pathogenesis of AD. Coconut can be useful in the treatment of obesity, dyslipidemia, elevated low-density lipoproteins, insulin resistance, and hypertension-these are the risk factors for chronic venous disease and type II diabetes, as well as for AD.
Managing Patients with Failing Kidney Allograft
Authors: Davis Scott , Mohan Sumit
Published: March 2021

Patients who receive a kidney transplant commonly experience failure of their allograft. Transplant failure often comes with complex management decisions, such as when and how to wean immunosuppression and start the transition to a second transplant or to dialysis. These decisions are made in the context of important concerns about competing risks, including sensitization and infection. Unfortunately, the management of the failed allograft is, at present, guided by relatively poor-quality data and, as a result, practice patterns are variable and suboptimal given that patients with failed allografts experience excess morbidity and mortality compared with their transplant-naive counterparts. In this review, we summarize the management strategies through the often-precarious transition from transplant to dialysis, highlighting the paucity of data and the critical gaps in our knowledge that are necessary to inform the optimal care of the patient with a failing kidney transplant.

Published: March 2021

Cultural understanding is important in peacekeeping operations since it emphasizes on cooperation of various parties including the cooperation of the local community. Without cultural tolerance from both sides, this operation are difficult to run smoothly and effectively and in fact, this can also lead to a worsen situation, such as the armed conflict between the peacekeeping forces and the local community. Therefore, this study is carried out by using semi-structured interview of 25 officers who have been assigned under United Nations peacekeeping operations and it is centered on three parameters namely pre-deployment training, high level of tolerance and impartiality in discharging their duties. Most officers agree that these parameters are the most significant attributes that could reduce cultural based conflict in the assigned areas.
New Stage in the Geopolitical Struggle around the Caspian Sea after 1991
Authors: Pritchin Stanislav Aleksandrovich
Published: March 2021

For almost three centuries, starting with the campaign of Peter the Great in 1721-1722, Russia has traditionally played a key role in the Caspian Sea. The situation changed dramatically with the collapse of the USSR in 1991 and the emergence of three new regional players-Azerbaijan, Kazakhstan and Turkmenistan. For Russia, this meant a significant reduction in influence in the region and the loss of control over most of the water area and the sea and its resources. In the historiography devoted to the region, the emphasis is placed on assessing the new round of geopolitical struggle, the position and interests of Western and regional powers. The author of this article provides a critical analysis of changes in Russian policy towards the Caspian Sea over the past 30 years and assesses the effectiveness of these changes. The difficult transition from the role of a dominant player in a region closed to external competitors to an open geopolitical confrontation over resources, their transportation routes, and political influence at the first stage was not in favor of Russia. Russia could not defend the principle of a condominium for joint development of hydrocarbon resources of the sea. With the active assistance of Western competitors, Russia lost its status as a monopoly transit country for oil and gas from the region. At the same time, thanks to diplomatic efforts and increased political dialogue with its neighbors in the region, Russia managed to resolve all territorial issues at sea by 2003, maintain the closed status of the sea for the military forces of third countries, and by 2018 complete work on the Convention on the international legal status of the sea, which established the principles of cooperation in the region that are important for the Russian Federation. Thus, official Moscow managed to achieve the strategic goals adapted after the collapse of the USSR by using the traditional strengths of its foreign policy and consolidate its status as the most influential player in the region.

The authors of this contribution analyze the circumstances and the history of a popular play that was staged in the Soviet Union in 1927-1928. Titled Jumah Masjid, this play was devoted to the anti-colonial movement in India. A manuscript of the play, not indicating its title and the name of its author, was found in the St. Petersburg Branch of the Archive of the Russian Academy of Sciences among the papers related to A.M. and L.A. Meerwarth, members of the First Russian Expedition to Ceylon and India (1914-1918). Later on, two copies of this play under the title The Jumah Masjid were found in the Russian Archive of Literature and Art and in the Museum of the Tovstonogov Grand Drama Theatre. The authors of this article use archival and published sources to analyze the reasons for writing and staging the play. They consider the image of India as portrayed by a Soviet playwright in conjunction with Indologists that served as consultants, and as seen by theater critics and by the audience (according to what the press reflected). Arguably, the celebration of the 10th anniversary of the October Revolution in Russia in 1927 and the VI Congress of the Communist International (Comintern) in 1928 encouraged writing and staging the play. The detailed picture of the anti-colonial struggle in India that the play offered suggests that professional Indologists were consulted. At the same time the play is critical of the non-violent opposition encouraged by Mahatma Gandhi as well as the Indian National Congress and its political wing known as the Swaraj Party. The research demonstrates that the author of the play was G.S. Venetsianov, and his Indologist consultants were Alexander and Liudmila Meerwarth.

Authors: Makhmutov Zufar A.
Published: March 2021

This article is devoted to the study of the functions by the Institute of Tatar mullahs in Kazakhstan at different historical periods. The author examines the activities of clergymen in the region, analyzes the internal policy of the Russian and later Soviet state, which regulated their activities by legislative acts, creating certain political contexts. Research interest is also caused by the internal policy of the state, which regulated Tatar mullahs activities by legislative acts and it created certain political contexts. The sources for writing the work were materials of personal origin and office work, legislative and regulatory documents stored in the archives of Kazakhstan and Russia. In the initial period of the Kazakhstan's colonization the institute of Tatar mullahs was integrated into the management system of the newly-joined territory. In these conditions, the Tatar clergy had rather large powers in the Kazakh steppe. They conducted civil proceedings, document management, taught the Kazakhs literacy and agriculture, participated in government decisions, and carried out diplomatic missions. Their work gave legitimacy to the actions of the empire for the Kazakhs and promoted loyalty to the new government. In the middle of the 19th century, the attitude of the tsarist officials towards the mullahs changed dramatically. Activity of Tatar clergy was significantly limited by the Temporary Provision of 1868. Despite the prohibitions being undertaken, the political and religious influence of the ulama on the Kazakhs remained quite strong. In Soviet times, a significant part of the Tatar clergy was destroyed and completely removed from the legal field. However, although they were in an illegal situation, they continued to perform religious functions. After some religious relaxation during the Great Patriotic War, they made a significant contribution to the formation of Kazakhstani Kaziyat. The author considers that Tatar mullahs were the elite of the mobilized diaspora оn the basis of the analyzed material. Tatar ulemahs conspicuous influence was until the middle of the 19th century and occurred outside the religious sphere as well.

Based on an analysis of archival documents and periodical press materials, the present paper studies the impact of the liberal reforms of Alexander II on the policies of the imperial authorities for the nomadic peoples of the steppe of Ciscaucasia: the Kalmyks, Nogais and Turkmens. The liberal reforms of the 1860s and 1870s had a direct impact on the formation of the national intelligentsia, which during the revolutionary events of the early 20th century led to the rise of the national movement in the empires peripheries and to the struggle for self-determination of the non-Russian populations during the Russian Revolution of 1917. The article reconstructs individual facts and events from the life of the nomadic population under specific socio-economic and political-legal conditions. Using the historical-genetic method, the influence of liberal reforms on the vital activity of the nomadic peoples of the Stavropol province is revealed. The authors focus on the activities of regional authorities during the period under review, which were liberal in nature and carried out in the context of the reforms of Alexander II. The authors conclude that the pre-Caucasus steppe, the territory of the nomadic Kalmyks, Nogais and Turkmens, being the national edge of the Russian Empire and falling under a special system of governance related to the ethnic and religious characteristics of the populations, was not drawn into the orbit of liberal reforms. Meanwhile, a number of measures were approved by the regional executive authorities on the ground, of course, first of all, aimed at satisfying the needs of the imperial policy for incorporating the region into the common imperial space, but at the same time improving the lives of the nomadic peoples of the Stavropol province, in particular in the field of education and legal procedures.

Recently, Europe is witnessing a transformation in the political system, concerning right-wing populist movements, around the claim that a massive influx of migrants within its territorial borders undermines the sovereignty of the nation-state. This transformation has led to issues of economic inequalities, loss of cultural identity, and influence in voting patterns. Considering the unfolding situations, we ask: What is the effect of educational migration on economic growth and social development before, during, and after the Covid-19 pandemic? How will the current political transformation processes affect educational migrants in the post-Covid-19 pandemic in Europe? Using the systematic review methodology, the authors sort to perform a comprehensive literature search; complete a critical appraisal of the individual studies gathered; and combine the valid studies using appropriate statistical techniques. The research affirmed a case that Education could not ignore politics. We perceive it will shape populist motives on educational migrants in post-pandemic Europe. The authors expectation of future research pays attention to the political transformation process and how anti-immigration discourse will exercise control over educational institutions.

The presented article is a study dealing with the role and characteristics of youth political online activism in modern Russia. The relevance, main aspects and criteria of the effectiveness of youth policy in the field of communication are considered. There are following basic steps suggested: to improve the effectiveness of such communication associated with a clear articulation of the needs of various groups of people through competent socio-political monitoring with independent quantitative and qualitative research. Building a constructive dialogue to promote positive, constructive and conventional activation of the political behavior of youth groups; work to overcome the apolitical and absentee tendencies of young people, as well as the expansion of the political and managerial concept of Electronic state not only formally, but also substantively, are among these steps. Further, the study analyzes the structure of protest behavior, distinguishes several levels of protest consideration, each of which has its own specifics and features for the analysis. This is the level of deep reasons and specific motive for the emergence of a public protest; the level of the dominant style of public manifestation of any protest moods, which has its basis in the predominantly psycho-emotional sphere; and, finally, the level of peculiarities of political behavior with very specific tactics and strategies of protest behavior. It draws attention to the fact that youth as a social group is heterogeneous and it seems appropriate to divide its age structure into three stages (from 14 to 20, years old, from 21 to 24 years old, and from 25 to 30 years old). The final part of the article deals with the models of virtual protest behavior. The model of a complete unstructured protest is highlighted; activity-target co-optation; proactive-loyalist; adaptation and frustration; politicized civil and local models. The results obtained to date make it possible to record the essential features of online mobilization, both based on the features of the functioning of the virtual space, and from the point of view of the main object of research: youth and the specifics of its identity and algorithms of political behavior. All this allows us to speak about the relevance of the constructed classification models for various mobilization mechanisms, which determines the practical significance of the study.
