Tendencias económicas y sociales recientes en la agricultura pampeana. Una crítica al enfoque de producción en red
Authors: García Bernado Rolando , Vértiz Patricio
Published: May 2022

Durante los últimos años han emergido en el ámbito de los estudios agrarios considerables críticas a uno de los enfoques que marcó las últimas dos décadas de investigación: el de las “empresas-red”. Estas críticas abonan a comprender de qué manera se han exagerado los aspectos “reticulares” del modelo productivo agro pampeano y, como contrapartida, se han subestimado otro tipo de transformaciones que reconfiguraron las relaciones productivas agrarias de manera significativa. En este sentido, argumentamos que para visualizar estos últimos aspectos se debe adoptar un enfoque centrado en las relaciones asimétricas entre sectores con base en la dinámica de la acumulación capitalista. Desde esta perspectiva analizamos las principales tendencias transformadoras de las relaciones sociales de producción en el agro pampeano durante el período 1990-2020.

Differentiated integration in MERCOSUR: Risks and opportunities for the association with the European Union
Authors:   Senior Research Fellow, CIDOB, Ayuso Pozo Anna
Published: May 2022

Asymmetries within MERCOSUR member states and vulnerability to financial crises forced the adoption of measures to facilitate flexibility. Differentiated integration was designed to handle centrifugal forces while preserving sovereignty and avoiding the paralysis that can result from a decisionmaking process that requires the consensus of all member states. The asymmetries not only affect the internal dynamics, but should also be taken into account in external relations and were a key issue in the negotiation of the association agreement signed with the EU in 2019.

Study on the crushing mechanism and parameters of the two-flow crusher
Authors: Huang-Yi Wu , Luo-Jian Yu
Published: May 2022

Based on a Chinese enterprise's single-mouth crusher, the ‘waterfall flow’ inlet crusher is developed from a foreign two-flow crusher. The two-inlet crushing mode has advantages of continuous particle feeding, controlled particle flow and low wear of housing. By analysing the working principle of the equipment, the three-dimensional model of the crusher is established. Based on the discrete element method, the simulation data are obtained by EDEM simulation software. The crushing energy, the wear of the housing and the counter boards are analysed to obtain the optimal parameters. The crushing efficiency is significantly improved and the wear of the housing is controlled to some extent. The overall performance of the crusher is improved and the cost is reduced.

Recently, the high cost of aquafeed affected fish farming feasibility in some countries, including Egypt. The imported soybean meal and corn ingredients consume a large amount of the hard currency, thereby increasing feed prices. Thus, the current study investigated the different sources of soybean and corn on the performances of Nile tilapia. Fish fed with the diet I (based on Egyptian soybean meal cultivar and cornmeal cultivar) or diet II (based on imported soybean meal cultivar and cornmeal cultivar) in a 90-day feeding trial. The results showed no marked effects on the growth performance, protein efficacy ratio, and FCR in the case of fish-fed diet I or diet II. No histological alterations were observed in the skeletal muscle, hepatopancreas, spleen, and intestines, while the diet I-fed group showed normal architecture of the above-listed organs. The expression of liver and muscle IGF-1 showed no changes in fish-fed diet I or diet II. No diet-related variations were observed in IL-1β expression in the spleen but increased regulation in the liver of the diet II group compared to the diet I group. Furthermore, significant upregulation of SOD and HSP70 genes was seen in the spleen and liver of the diet II-fed group. We conclude that the inclusion of the Egyptian soybean meal cultivar and cornmeal cultivar (diet I) did not reduce the growth performance and immune-related genes compared with the imported soybean meal cultivar and cornmeal cultivar (diet II).
Parvovirus B19 infection during pregnancy
Authors: Pietruszka Katarzyna , Sliwinska Magdalena , Sikora Agnieszka
Published: May 2022

Parvovirus B19 (B19V) is a widespread pathogen causing infection that occurs mostly in children. Even though infection of B19V is mainly asymptomatic, it can bring about a few conditions that may require medical intervention, including erythema infectiosum (fifth disease), slapped cheek syndrome, papular-purpuric gloves and socks syndrome (PPGSS), as well as other disorders related to the hematological system. Despite the fact that the most common route of transmission is through the respiratory system, B19V can be also transmitted transplacentally from mother to foetus. Vertical transmission may lead to myocarditis, thrombocytopenia, neural manifestations, and foetal hydrops, which may be life-threatening conditions to both mother and foetus. Detection of B19V infection is based mostly on molecular and serological screening and it is performed after suspected exposure to pathogen or exhibition of symptoms. Currently, there is no specific medication against B19V infection, therefore, treatment is based on the elimination of symptoms. New therapies are, however, under development.
Emerging role of macrophages in diabetic nephropathy
Authors: Lan Hui-Yao
Published: May 2022

Increasing evidence shows that diabetic nephropathy is associated with immune disorder. Macrophages are a key immune cell infiltrating the kidney in both patients and experimental animal models of diabetes, and correlate with progressive renal injury under diabetic conditions. Blockade of renal macrophage infiltration by either genetic deletion or pharmacological inhibition has been shown to improve diabetic renal injury, revealing a pathogenic role of macrophages in diabetic nephropathy. Further, studies identify that M1 macrophages are a key player responsible for diabetic renal injury by triggering renal inflammation, while M2 macrophages are highly heterogenous, and may play diverse roles in either initiating the renal repairing process if renal inflammation is resolved, or promoting progressive renal fibrosis via a macrophage-to-myofibroblast transition (MMT) process if renal inflammation is ongoing. Macrophages may also interact with intrinsic kidney cells to mediate renal inflammation or fibrosis directly or indirectly by producing a variety of proinflammatory cytokines/chemokines and growth factors, or by macrophage-derived exosomes. In summary, macrophages are immunologically important in the pathogenesis of diabetic kidney disease and may play a driving role in the progression of diabetic nephropathy. Targeting macrophages may thus be considered as a novel therapy for combatting diabetic nephropathy.
Load Spectrum Analysis with Open Source Software – An Application Example
Authors: Łukasiewicz Marek S.
Published: May 2022

Processing of digital experimental data has become a key part of virtually every research project. As sensors get both more diverse and cheaper, the amount of information to be handled greatly increases as well. Especially fatigue failure modelling requires by its nature large numbers of samples to be processed, and visualised. The presented paper is based on analysis of load data gathered in flight on an unmanned aircraft. A few versions of an analysis program were developed and considered for the use case. Each implementation included ingesting the data files, creating transfer arrays and the “rain flow counting” algorithm. For the sake of the ease of use and functionality, the version based on Python programming language was selected for presentation. Short development iteration time of this approach allowed gaining new insights by tweaking parameters to better represent actual acquired data. Both the results and the software itself can be easily viewed in a web browser and run with modifications without the need to install any software locally. The developed software is meant as a demonstration of capabilities of open source computation tools dedicated to aerospace and mechanical engineering research, where they remain relatively unpopular.
The preparation of CNT/PMMA composite film on SiO2 substrates
Authors: Li Jian
Published: May 2022

Microelectromechanical system (MEMS) has been highly valued since the size of the MEMS structure is miniaturized, the spacing between the components is in the nanometer range, and the behaviors of friction and adhesion greatly affect the reliability of MEMS. An atomic force microscope (AFM) was used to observe the surface morphology of carbon nanotube (CNT)/polymethyl methacrylate (PMMA) film, and X-ray photoelectron spectroscopy (XPS) was used to analyze the chemical state of typical elements on the surface of the film. The friction and wear properties of composite nano-films under macroscopic conditions were systematically studied. The research results show that the composite nano-film has excellent anti-friction and anti-wear properties.
The dose accumulation and the impact of deformable image registration on dose reporting parameters in a moving patient undergoing proton radiotherapy
Authors: Razdevsek Gasper , Simoncic Urban , Snoj Luka , Studen Andrej
Published: May 2022

Introduction

Potential changes in patient anatomy during proton radiotherapy may lead to a deviation of the delivered dose. A dose estimate can be computed through a deformable image registration (DIR) driven dose accumulation. The present study evaluates the accumulated dose uncertainties in a patient subject to an inadvertent breathing associated motion.

Materials and methods

A virtual lung tumour was inserted into a pair of single participant landmark annotated computed tomography images depicting opposite breathing phases, with the deep inspiration breath-hold the planning reference and the exhale the off-reference geometry. A novel Monte Carlo N-Particle, Version 6 (MCNP6) dose engine was developed, validated and used in treatment plan optimization. Three DIR methods were compared and used to transfer the exhale simulated dose to the reference geometry. Dose conformity and homogeneity measures from International Committee on Radioactivity Units and Measurements (ICRU) reports 78 and 83 were evaluated on simulated dose distributions registered with different DIR algorithms.

Results

The MCNP6 dose engine handled patient-like geometries in reasonable dose calculation times. All registration methods were able to align image associated landmarks to distances, comparable to voxel sizes. A moderate deterioration of ICRU measures was encountered in comparing doses in on and off-reference anatomy. There were statistically significant DIR driven differences in ICRU measures, particularly a 10% difference in the relative D98% for planning tumour volume and in the 3 mm/3% gamma passing rate.

Conclusions

T he dose accumulation over two anatomies resulted in a DIR driven uncertainty, important in reporting the associated ICRU measures for quality assurance.
Avoiding Food Wastage: The Net Impact of Maisto Bankas Activities. A Carbon Footprint Approach
Authors: Meloni Giuditta , Rocchi Lucia
Published: May 2022

Food wastage is a complex global issue. Its solution requires a multi-pronged effort and the use of diversified strategies. Since the impacts are on an environmental, social and economic level, solutions can take shape in one of these areas, knowing that there are often trade-offs between one and the other. This paper aims to evaluate the net environmental effects in terms of Carbon footprint of the activities of the Lithuanian Food Bank (Maisto Bankas). Food banks are charities that work to reduce the negative social effects associated with food waste and food insecurity. They work on the food recovery, avoiding the transformation of food surplus in food waste. The present paper assessed the positive impact generated by the Lithuanian Food Bank thanks to its activities as the non-impact of recovered food and the non-disposal of food in landfills. At the same time, also the negative impact in term of emission due to the management of all its activities has been estimated. The net impact has been derived by the comparison of the two flows. The results of the study proved that, behind the social benefit, the Food Banks, as Maisto Bankas, produce also a net positive environmental impact.
Reconsidering Resistance: Ainu Cultural Revival as Protest
Authors: Powell Courtney
Published: May 2022

This article aims to explore how different Ainu groups have resisted continual control and assimilation by the Japanese government in the late twentieth century. First, it provides a brief analysis of early resistance strategies of ethnic groups to colonial power, contrasting it with contemporary methods of protest in the post-war era. This is to show the different modes of resistance and to analyse why and how they changed over time. The article highlights the period between the 1970s and 1990s, during which violent resistance committed by Japanese progressive activists in the name of Ainu liberation was gradually succeeded by peaceful protest enacted by Ainu themselves, resulting in a movement using artwork in pursuing their political goals. The article argues that this latter kind of resistance represents the core of Ainu activism. I will analyse cultural resistance efforts such as literary publications, commemorative monuments, and educational programmes since the 1970s. Special attention will be given to three children’s books produced by prominent Ainu activist Kayano Shigeru to discuss how the author’s cultural activism during this period shaped Ainu methods of contesting authority through cultural pride and maintenance.
COVID-19 and Mobile Payment Diffusion: Lessons for Future Mass Diffusion and Continual Usage
Authors: Coffie Cephas Paa Kwasi , Tetteh Emmanuel Dortey , Emuron Abraham , Darkwah Joseph Asante
Published: May 2022

Covid-19 transformed mobile payment services (MPS) diffusion pattern globally. Consequently, the need to examine factors contributing to the diffusion rate of MPS in this era is substantiated. Thus, this study employs Structural Equation Model (SEM) with social media administered survey data to estimate the nexus between MPS diffusion and technological factors, non-technological factors, and environmental factors. Results suggest that although MPS diffusion increased globally, mobile payment services have the highest diffusion rate. This is because of convenience, availability, and cost. Further, technological, non-technological, and environmental factors all contribute positively to the high rate of diffusion. Environmental factors like an escalation in the Covid-19 cases, recommendations from the center for disease control positively mediates the relationship between MPS diffusion and non-technological factors. Thus, to encourage mass diffusion and continual usage of MPS during and after the pandemic, cost of usage, convenience, accessibility, and mobile-based applications should be bundled for optimized user experience.

Authors: Lebedeva A. A. , Kulikov A. N. , Kovalchuk I. P. , Kadinskaya M. I. , Ginzburg A. M. , Vlasov T. D.
Published: May 2022

Introduction. The novel coronavirus infection COVID-19 (NCI COVID-19) caused by the COVID-19 virus, which occurs in the most severe forms, is accompanied not only by the development of respiratory failure and acute respiratory distress syndrome, but also by other equally dangerous complications such as covid-associated coagulopathy.

The objective was to study the clinical and laboratory features of the development of endothelial dysfunction as the main component of covid-associated coagulopathy in the context of its most common manifestation – thrombotic events.

Methods and materials. The medical records of 947 patients with confirmed novel coronavirus infection COVID-19 hospitalized at the Center for the Treatment of Patients with NCI COVID-19 of Pavlov University of the Ministry of Health of the Russian Federation during the so-called «2nd wave» of the pandemic from November 2020 to March 2021.

Results. All thrombotic complications were detected only in patients with severe coronavirus infection (561 patients). Predisposing factors for the development of thrombosis in our patients were: advanced age, duration of hospitalization for more than 1 week, comorbidity in the form of coronary artery disease. Standard screening tests of the hemostasis system (platelet microscopy, coagulogram screening) do not reveal any significant features in the presence of thrombotic events, which requires the development of new studies to assess prothrombotic potential in patients with severe NCI COVID-19.

Conclusion. The development of thrombotic events is one of the most formidable complications in the severe course of NCI COVID-19, which in turn leads to an increase in respiratory failure due to increased tissue hypoxia, and subsequently to death. The same patients have an increased risk of hemorrhagic events as a possible side effect of the therapy.

Adaptation potential of medical students in distance learning
Authors: Toussova O. V. , Pavlova O. V.
Published: May 2022

Introduction. The coronavirus pandemic provoked a sharp transition from the classical form of education to distance learning, which has become widespread over the past year and a half. Both students and professors are forced to adapt to the changing conditions of learning and life in general. The current situation of uncertainty caused stress reactions and actualized the adaptive potential of the psyche. There are practically no studies on this topic, which explains the novelty and relevance of this work.

Methods and materials. The article is devoted to the study of adaptive features of medical students in distance learning. To study adaptive features, a multilevel personality questionnaire (MLPQ) «Adaptability» was used (A. G. Maklakov, S. V. Chermyanin, 1993). To study the causes of educational stress in students and strategies for coping with stress, the Lazarus coping test and the test for educational stress (Yu. V. Shcherbatykh) were used. To study the attitude of students to full-time and distance learning, a specially designed questionnaire was used. Statistical processing was carried out using SPSS Statistics 21.

Results. The study was conducted in the spring of 2021. 100 first-year students of Pavlov University participated in it. The average age of the sample was (18.32±1.5); among them: 29 men and 71 women. The leading causes of educational stress were: a large study load (7.32), a large amount of educational material to memorize (7.20), difficulty in understanding the material (6.99) and the presence of working off (6.82), which were introduced to eliminate debt. The leading coping strategies in distance learning were «self-control» (13.29), «problem solving planning» (13.21) and «positive reassessment» (12.99). The most common ways to cope with stress were sleep (17 %), delicious food (15 %), socializing with friends (14 %), outdoor activities (13 %), and support or advice from parents (12 %). Distance learning students had an average level of adaptive potential. Students with a higher adaptive potential in dealing with stress significantly more often (p≤0.01) use the strategies of problem solving planning and positive reassessment, while students with a lower adaptive potential significantly more often (p≤0.05) in a stress situation use «accepting responsibility» and «escape-avoidance» copings.

Conclusions. The conducted study allowed to identify the causes of students’ educational stress, strategies of behavior and coping with stressful situations, which should be taken into account in the organization of the learning process and in the work of a psychological service to increase the acquisition of knowledge and academic success of students. The obtained results made it possible to identify the advantages and disadvantages of full-time and distance learning, which allows us to make an assumption about the optimal combination of both forms in the further educational process.

The objective was to improve the efficiency and safety of surgical treatment in elderly patients with morbid obesity.

Methods and materials. The study included 20 patients with morbid obesity aged 60 to 69 years. The following scores and indices were used to assess the comorbidity of patients and the risk of complications from surgery: OS-MRS, Charlson comorbidity index, Caprini score, HAS-BLED score.

Results. The course of the postoperative period in elderly patients with morbid obesity was smooth in 17 (85 %) people and did not differ from that in middle-aged patients, subject to careful preoperative examination and preparation. The factors of the initial comorbid background and the duration of the operation had the greatest influence on the result of bariatric surgery.

Conclusion. Bariatric surgery in elderly patients with morbid obesity should be carried out taking into account careful selection, examination and assessment of the risk of adverse outcome in a specialized surgical center of a multidisciplinary hospital.
Understanding the pathogenic and nonpathogenic mutations and implications of α-galactosidase variant D313Y in Fabry disease
Authors: Ezzat Aly , Bagoury Marwan , Roushdy Sherif , Aktham Yahia
Published: May 2022

Fabry disease (FD) is a rare, progressive, inherited disorder resulting from a markedly deficient enzyme activity of α-galactosidase A (AGAL), which is caused by mutations in the X-linked α-galactosidase A (GLA) gene. FD is perceived as a multidomain or a heterogeneous disease phenotype associated with complex pathophysiological manifestations and cascading pathways. The AGAL activity accurately predicts the severity of FD. It is vital to study the variants related to FD in the Gulf region because the existing population is mixed, and a founder gene, if predominant in any generation, leads to greater birth rates of autosomal recessive disorders. Identifying the pathogenicity of GLA mutations plays a crucial role in diagnosing and treating FD. We conducted an extensive review of the literature. We pooled data from randomized controlled trials, retrospective observational trials, systematic reviews, and case reports on p.D313Y variant pathogenicity versus nonpathogenicity and clinical significance for establishing genotype-phenotype correlations in patients with suspected FD. Overall, in our review analysis, we included 25 studies. Data on study participants, type of mutation, clinical manifestations, and clinical relevance were collected. Interestingly, we found strong evidence reporting nonpathogenicity of the D313Y variant and categorized it as benign or a variant of uncertain significance. These results will facilitate the clinicians to decide on the correct diagnosis and treatment of FD. Further research is warranted, which would help clarify a possible relationship between the variant and clinical manifestations.

Marxist Humanism in the USSR: the Creative Development of Marxism-Leninism or reaction?
Authors: Emel'yanov Andrei Sergeevich
Published: May 2022

The article analyzes the features of the formation of Marxist humanism in the Soviet Marxist-Leninist philosophy of the 50s and 60s. The prerequisites for the emergence of Marxist humanism in the USSR, in addition to the material of the "Manuscripts of 1844", should include the widespread spread of social democratic revisionism among representatives of Soviet social science thought. The article pays special attention to the influence of foreign tradition on the content and problems of domestic Marxist humanism (in particular, the French Communist Party and such theorists as R. Garodi and L. Sav). In addition, the study analyzes the conceptual positions of Soviet philosophers regarding the nature of humanism during the period of socialist construction (M. Petrosyan, P. Fedoseeva, G. Smirnova, I. Frolova). In particular, the issues of the correlation of socialist and bourgeois humanism, the correlation of personal and social under the socialist system, the concept of "comprehensive personality development" under communism, discussions about Marxist anthropology are considered. В  At the same time, it is emphasized that the solution of these (and some other) issues proposed within the framework of domestic Marxist humanism was idealistic and divorced from the real practice of socialist construction. In conclusion, the article concludes that Marxist humanism in the Soviet Union was not a creative development of the provisions of Marxist-Leninist philosophy, but was, for the most part, a reworked social-democratic and neo-Marxist revisionism. In our opinion, this conceptual and categorical "sabotage" led to the theoretical and ideological substitution of Marx's provisions instead of their development, which became one of the reasons for the "decomposition" of the party and its loss of the status of the "leading force of the proletariat" in the USSR.
Language reforms in France of the XVII century and the formation of gallant aesthetics.
Authors: Zaуtseva Nataliya Vladimirovna
Published: May 2022

The study of language as a carrier of a new aesthetic ideal in the first half of the XVII century in France and language reforms as a consequence of the emergence of a new ethos are at the intersection of sociolinguistics, history and cultural studies. For almost three centuries, French has been not only the language of international communication, like Latin. He carried a new aesthetic, introduced new literature, gave an opportunity to join a new manner of behavior and lifestyle in general. French became not so much the language of educated people, like Latin, as the language of secular educated people, it expressed the ideals of gallantry, good manners and upbringing, which foreigners came to Paris to study. To explain the phenomenon of the spread of the French language and the influence of French culture not only on Russia, but also on other European countries, it is necessary to return to the language reforms of the XVII century, when the language becomes a reflection of a new aesthetic. This study aims to show why the discussion around language flows into a discussion about style, and it, in turn, about the superiority of the new aesthetics. The reforms of the French language, on the one hand, were the result of the establishment of new aesthetic principles in the consciousness, on the other hand, they influenced the aesthetic principles of their time. Simplicity, naturalness and purity of style, clarity of expressions that convey exactly the thoughts come to French literature and later transferred to art as a whole. The successes of linguistic and literary reforms for contemporaries are associated with the political successes of France, because "the greatness of the empire and the elegance of the language always go hand in hand."

Authors: Mikheeva Vitalina Vladimirovna
Published: May 2022

The object of the study is the system of non-state higher education in Russia. The subject is the analysis of historical research devoted to the difficult process of formation and development of a private higher school in Russia in various periods of national history. The methodological basis is the dialectical principles of the relationship between the process and the result, individual, special and general. In addition, there is a systematic approach that helps to identify the state of knowledge of the stated problem. A comparative historical method has also been used to explain the historiographical facts of the history of private education in connection with the historical situation, a retrospective method that contributes to complementing the picture of the development of historical and pedagogical events in our country. Relevance of the research topic. Democratic reforms in Russia in the 90s of the XX century contributed to the creation of conditions for the emergence of a non-state higher school. The State Higher School was unable to respond promptly and on a large scale to the changing situation in the country, the growing interest in education, the emergence of new professions and specialties, the provision of additional earnings to the teaching staff of state universities, etc. In these conditions, the non-state sector of higher education has experienced its rebirth, which is waiting for its reflection. The scientific novelty and theoretical significance of the conducted research are as follows: the trends in the development of the Russian system of private higher education from the moment of its birth to the present are outlined; the definition of the term "private higher school" is given; conclusions were drawn in the article about the state of domestic knowledge on the history of private higher school.
