Current State and Conditions of Landscape Formation of Ilovlya River Floodplain (Middle Don)
Authors: Solodovnikov Denis , Shinkarenko Stanislav
Published: June 2020

The basis for the study is instrumental terrain profiling using level, geobotanical descriptions, GPR studies, soil sections and manual drilling with a soil sampler. The species composition of vegetation indicates very rare and short-term flooding in high water. Vegetation elements of the low floodplain are marked on the areas directly adjacent to the riverbed at altitudes up to 1.5 m above the inter-level level. Further, along the profile, there are no signs of flooding and standing water. In the soil section there are no iron oxide (II and III) and fading of salts in all horizons up to the depth of 150 sm. The borders between horizons are expressed unclear. This indicates sufficient surface moisture and thus washing of the upper horizons of the soil. The floodplain oak forest is in good condition, there are no dry-top trees. This also indicates that the soil and groundwater are not saline. Studies have shown that the location of the groundwater mirror is close to horizontal, and its level exactly corresponds to the water level in the river. This position of the ground water mirror is typical for river floodplains that occupy an intermediate position between the floodplains of humid and arid zones. The relief of the river floodplain was formed in more water years than observed in the late 20th – early 21st centuries. The first floodplain level (low floodplain) has an excess of no more than 1–1.5 meters above the inter-level of the river. In modern hydrological conditions, only this level is guaranteed to flood every spring.
Comparative Analysis of Oil Production in Russia and Abroad

Published: June 2020

The modern oil complex of the Russian Federation makes a significant contribution to the formation of a positive trade balance and tax revenues to budgets of all levels. This resource makes up more than 16 % of Russian GDP, a quarter of tax and customs revenues to budgets of all levels, and more than a third of the incoming foreign exchange revenue. The article presents the analysis of Russian companies which currently produce much less oil than west companies, except “Lukoil” company. The main reasons for the decline in production are considered to be the lack of financial resources for investment, the underdevelopment of the Russian export infrastructure, and low domestic demand for the products of the industry. At the same time, lower rates of developing existing reserves in Russia in comparison with the west can provide a much longer duration of their operation. One of the priorities for Russian companies is the availability of large oil reserves. At the same time, this advantage is largely lost due to high taxes and low prices for final products. The main disadvantages of Russian companies are considered to be a high degree of financial vulnerability and low efficiency of production activities in comparison with the leading companies of the west. However, the Russian Federation remains an undisputed world leader in oil production and export. The analytical review characterizes the Russian oil complex as a sector of fuel and energy potential and the contribution of oil production to the country’s economic development, the existing resource potential of both oil fields and their number, and recently discovered oil fields. The paper estimates the cost of oil from leading oil producers and the technological capabilities of extracting oil from hard-to-reach fields and describes the resource potential of OPEC countries, Russia, and the United States. The resulting analytical conclusion is the given options for improving the innovative sphere of Russia to increase the efficiency of oil production and development of hard-to-reach oil fields.
To Defeat Him by Quoting Lenin and Facts: Practices of the Political Cult in Discussions of the 1920s
Authors: Rakov Timofey
Published: June 2020

This article analyses practices related to the cult of Lenin in the confines of the Leningrad party organisation of the RCP(b) and its influence on innerparty discussions and political disagreements. The author aims to examine how appeal to the cult and Leninism helped shape the position of the Leningrad Bolsheviks led by G. E. Zinoviev. To achieve this goal, the author refers to a variety of sources, i. e. the works of the leaders of the Leningrad party organisation, such pamphlets by G. I. Safarov and G. E. Evdokimov, minutes of district party conferences, etc. The sources listed above suggest that the terms “testament,” “heritage,” and “task” used in party discourse symbolise a set of actions and principles, following and being faithful to which allowed party members to comply with the correct political line. For representatives of the Leningrad opposition, this meant relying on the poor and middle strata of the village. The category of practice mentioned in the title of this article means that attention was paid not so much to the function of quotations or clichéd phrases but rather to what party groups implied when quoting Lenin’s statements. The term “cult”, which historiography usually employs to describe the veneration of V. I. Lenin as the leader of the party, does not reflect the entirety of this process or take into account its productive component, namely, the fact that, because of its heterogeneity, Leninism allowed members of the Communist Party to pay attention to diverse aspects of Lenin’s heritage. In the course of the polemic surrounding issues facing the party (politics in the countryside, the possibility of building socialism in a single country, etc.), the Leningrad Bolsheviks turned to Leninism as a range of ideas legitimising their political position and as a tool for identifying the Bolsheviks who, in contrast to the Leningraders, “deviated” from the correct political line.
Use of fine aggregate matrix to analyze the rheological behavior of cold recycled materials
Authors: Graziani Andrea , Raschia Simone , Mignini Chiara , Carter Alan , Perraton Daniel
Published: June 2020

Nowadays, one of the main challenges to a wider application of cold recycling techniques is the lack of reliable information on the mechanical behavior of cold recycled materials (CRM). In this context, measurement and modelling of the complex modulus of CRM mixtures may give an important contribution to the design and analysis of pavements including cold recycled layers. In this study, we analyzed the rheological behavior of CRM mixtures produced using bitumen emulsion and cement through the study of their fine aggregate matrix (FAM). Starting from a fixed CRM mixture composition, we compared different FAM mortars, focusing on the effect of water and air content. Then, we selected a composition as representative of the FAM in the mixture and investigated the evolution of both materials during a fixed curing period. Next, we measured the complex modulus of the CRM mixture and FAM at two curing stages and applied a rheological model to simulate and compare their behavior. Results showed that the properties of CRM mixtures are comparable to those of FAM mortars produced using all the binding agents (bitumen emulsion and cement) and a fraction of the voids contained in the mixture. Despite the huge difference in volumetric compositions, the FAM mortar controlled the curing and the thermo-rheological behavior of the CRM mixture, while the coarse reclaimed asphalt aggregate fraction and the voids mainly affected the asymptotic properties (equilibrium and glassy moduli) and the non-viscous dissipation component.
Contrast of concrete dynamic constitutive models and simulation of vessel–bridge collision
Authors: Zhou Mi , Wu Jiang , Song Jianwei , Zhu Guoqiang , Wang Chao , Lee George C.
Published: June 2020

Long-span bridges are constructed to cross oceans or rivers. With the rapid growth of waterway transportation, vessel–bridge collision incidents now occur in large numbers. In order to provide better understanding of the actual responses of bridge structures under impact load, vessel–bridge collisions were simulated using the non-linear finite-element method. Four commonly used dynamic constitutive models of concrete are described in this paper. Two impact tests (a rigid ball striking a target concrete wall and a hammer striking a reinforced concrete (RC) beam) were simulated using LS-Dyna. It was found that the RC damage model was more suitable for simulating the inelastic responses of cracks than the other three models. Based on the RC damage model, a typical bridge substructure subjected to a 1000 dead-weight-tonnage vessel collision was numerically simulated. An empirical formula for estimating the maximum impact force was then developed. This formula, which considers the reinforcement ratio and the vessel collision velocity, is suggested for practical vessel–bridge design. The proposed empirical formula and the equations recommended in codes from different countries were compared and it was found that the assessment of vessel collision force using the new formula is significantly improved.
Antifungal activity of useful microorganisms against a phytopathogenic fungus on maize
Authors: Arici Serife Evrim , Tuncel Ziynet Nurcin
Published: June 2020

Fusarium stalk rot (FSR) caused by Fusarium verticillioides (=moniliforme) significantly affects the productivity of maize (Zea mays L.). The aim of this study was to determine the effect of Trichoderma harzianum, mycorrhizal fungi (Glomus spp.), Aspergillus niger and Bacillus subtilis for biocontrol potential of FSR using dual-culture bioassays and greenhouse bioassays on maize. As a result, T. harzianum, mycorrhizal fungi (Glomus spp.), A. niger and B. subtilis showed inhibitory or reducing activities against mycelial growth of F. verticillioides in dual culture. A. niger and T. harzianum were the most effective suppressants of F. verticillioides, and B. subtilis was the least effective. Application of B. subtilis significantly reduced FSR symptoms in greenhouse-grown maize. At the end of the experiment, the spore density of biological control preparations were increased in soil/root samples. Treatments of mycorrhizal fungi (Glomus spp.), T. harzianum, A. niger and B. subtilis suppressed the development of F. verticillioides in soil. In addition, mycorrhizal fungi (Glomus spp.), T. harzianum, A. niger and B. subtilis also significantly improved the plant growth parameters. It is concluded that mycorrhizal fungi (Glomus spp.), T. harzianum, A. niger and B. subtilis have potential against FSR and these should suppress occurrence of FSR in maize-growing regions.
Evolution of particle morphology and mode of fracture during the oedometric compression of sand
Authors: Seo Dawa , Sohn Changbum , Cil Mehmet B. , Buscarnera Giuseppe
Published: June 2020

This work uses synchrotron X-ray tomography to quantify the role of the particle shape on the interaction between collective comminution and individual grain fracture. Two sands (subrounded Ottawa and subangular Q-ROK#2) were compressed beyond their comminution pressure and imaged at the microscale. An algorithm was developed to track the sequence of breakage events stemming from compression, as well as the evolving morphology of the resulting fragments. The results show that the degree of grain shape evolution depends on the initial morphology of the particles, with subrounded particles exhibiting the most severe shape alterations. However, it was found that at high compressive stress all morphological indices approach similar values. Such a tendency is achieved when crushing involves primarily the finer grain fractions – that is, when cushioning hinders the rupture of larger particles. A quantitative assessment of the mode of particle failure also revealed that in both sands comminution (i.e. the pervasive fragmentation of individual particles) was not achieved abruptly, but was rather attained by way of successive stages of splitting and chipping. These findings suggest that in crushable granular solids the initial grain shape plays a key role during the first stages of compression leading to yielding, but its influence tends to vanish at higher pressures, when cushioning mitigates the impact of initial morphological differences and hinders further major breakage.
Los contratos de consumo en Colombia
Authors: Rico Charry Hermes Fernando
Published: June 2020

Objetivo: el objetivo general del presente artículo fue realizar un análisis sobre el contrato en general y el contrato de consumo en particular, a través de una investigación propositiva que se basó en una metodología dogmática y en un análisis doctrinal, jurisprudencial y legislativo.

Metodología: a partir del análisis propuesto, se expondrá el estudio de diferentes conceptos y posiciones sobre los contratos y sus elementos de formación: la oferta, la aceptación y el perfeccionamiento del contrato, para después abordar el contrato de consumo, sus características como contrato asimétrico y su relación con el contrato de adhesión, finalizando con una conceptualizacion del contrato de consumo como un contrato normado.

Conclusiones: el perfeccionamiento del contrato requiere cumplir con las condiciones de la promesa y con las formalidades que ha estipulado la ley para cada caso de contrato. Los contratos de consumo son asimétricos, porque el poder económico y la información son detentados por los productores o comerciantes frente a los consumidores. A su vez, el contrato de consumo es un contrato normado, con un nivel de protección especial debido a que no existe igualdad alguna entre los contratantes, pero esta protección es insuficiente, dada la dinámica de las formas de ofrecer y comprar bienes de consumo, que evoluciona hasta el punto de que la legislación al respecto, generalmente, está atrasada para generar el desequilibrio entre productores y/o comercializadores y consumidores.
From modernization to deterritorialization: dynamics and dilemmas of agricultural work in the Cerrado of Piauí, Brazil
Authors: Silva Antonio Joaquim da , Monteiro Maria Do Socorro Lira , Barbosa Eriosvaldo Lima
Published: June 2020

O agronegócio tem se manifestado como um dos principais mecanismos de desterritorialização da identidade cultural do agricultor familiar do cerrado piauiense, haja vista que a recente ocupação empresarial do município de Uruçuí, conformada na modernização, nos princípios da agronomia científica e nos procedimentos de gestão administrativa, visando à produção em larga escala, sobretudo, soja, e a conquista de mercados, tem interferido na paisagem, no trabalho, no uso da terra, nos costumes, nos hábitos e nas práticas socioculturais, atingindo o ecossistema e gerando conflitos sociais, como a concentração fundiária, configurando uma grave crise socioambiental. Assim, faz-se necessário questionar o contexto de ocupação do cerrado uruçuiense pelo agronegócio e suas repercussões sobre a continuidade da agricultura familiar. Nesse sentido, salienta-se que este artigo pretende analisar a desterritorialização provocada pelo agronegócio granífero na agricultura familiar de Uruçuí. Este estudo descritivo/explicativo se embasou nos métodos dialético e etnogeográfico, os quais foram subsidiados por pesquisas bibliográfica, documental e levantamento, como também por formulários semiestruturados aplicados entre 254 agricultores familiares de Uruçuí. Concluiu-se que o processo de desterritorialização em Uruçuí, ocasionado pela difusão do agronegócio granífero, confirmou-se, mormente, na subordinação da mão de obra familiar ao trabalho temporário nas grandes propriedades agrícolas, pois a mesma era desvalorizada, apresentando baixo nível de especialização e reduzida remuneração salarial; na diminuição das relações de ajuda mútua entre as comunidades rurais; em mudanças nos modos de vida; e na eminente dependência dos agricultores familiares à aplicação idílica de insumos químicos nas lavouras.
Análise de competitividade em clusters de negócio: uma consolidação de parâmetros
Authors: Azevedo Ana Cláudia , Pereira Cristina Espinheira Costa , Cunha Mascena Keysa Manuela
Published: June 2020

Compreender a competitividade dos clusters requer uma análise para além da concentração geográfica, contemplando outros fatores determinantes desta competitividade. No entanto, não existe consenso em relação a estes fatores e, consequentemente, não há uma consolidação das métricas para operacionalizá-los, constituindo um entrave para realização de estudos aplicados a esses objetos. Diante disso, o objetivo deste estudo foi identificar, comparar e consolidar modelos empregados na análise da competitividade de clusters a partir de estudos nacionais. Para tanto, realizou-se uma revisão sistemática em artigos da base SPELL publicados entre 2000 e 2016. Identificou-se a utilização de dezessete modelos, contemplando vinte fatores de competitividade e, para cada fator, consolidou-se uma métrica e seu referencial de avaliação. Os fatores de competitividade mais relevantes foram a cooperação, e, abrangência de negócios viáveis e relevantes. A contribuição desta pesquisa é predominantemente metodológica fundamentada no fornecimento de parâmetros consolidados para análise da competitividade de clusters de negócios.
La ciudad y la región: imágenes y realidades revisitadas
Authors: Preiss Osvaldo , Schroeder Romina Valeria
Published: June 2020

Na construção de um referencial teórico que possibilite abordar a relação entre cidade e região, é pertinente analisar se a teoria e a metodologia, que se posicionam como ortodoxia vigente, se mostraram adequadas para o estudo do desenvolvimento das regiões, ou se trajetórias urbanas e regionais devem ser abordadas, incorporando elementos ausentes que nos permitam visualizar sua dinâmica. Para nosso conhecimento, pretender entender a cidade descontextualizada de sua inserção em regiões e territórios específicos representa uma abstração incompleta, que não apenas fragmenta a análise do urbano, mas também os processos de reprodução do espaço como um todo. Propõe-se rever a relação entre cidade e região nos fundamentos das teorias predominantes na literatura, que constituem a corrente principal do pensamento urbano e regional desde a década de 1980, e em visões alternativas, que destacam a heterogeneidade do trajetórias dos territórios, especialmente referentes às contribuições de autores latino-americanos.

The Entanglement of Class, Marriage and Real Estate: The Visual Culture of Egypt’s Urbanisation
Authors: Hendawy Mennatullah , Stollmann Jörg
Published: June 2020

A majority of scholars consider Egypt’s urban development a product of the neo-liberal political economy facilitated by the country’s central government. In this article, we want to shift our attention towards the public and its demand for housing. We describe the urban everyday experiences of a population within a country in which a visual culture established via public media creates an urban imagination that does not reflect the lived social, spatial, and economic reality of the majority of the population. Exploration of the general public’s attitudes towards media narratives that focus their advertisement campaigns on high class residential projects launched this investigation. The argument that follows is based on empirical studies within the Greater Cairo Region (GCR). In this setting, a puzzling trend from our collected data guides our central research question: Why aren’t ads for luxury housing—a market segment clearly beyond the reach of most Egyptians—condemned by those who cannot afford it? To tackle this phenomenon, we shed light on how the pre—and post-marital demand for housing among young couples and their families influence the market, and particularly, the market for upscale and luxury housing in Cairo. The research consists of four phases, including (1) field interviews with Uber and Careem drivers, (2) an online survey targeting inhabitants across varying urban and social segments of the GCR, (3) the first author’s personal story, which posits that marriage culture acts as a key driver for real estate narratives, and (4) a visual analysis of a real estate advertisement. To conclude, the article discusses how far a hegemonic visual culture that caters to socio-economic links between class, marriage, and real estate engages the support of a large part of the population, which in turn, co-produces a spatially unjust urban development scheme that works against their own interests.
Balance de agua y sedimentos durante el vaciado del embalse de Sant Llorenç de Montgai (Río Segre)
Authors: Béjar María , Vericat Damià , Palau Antoni , Batalla Ramón J.
Published: June 2020

Los embalses se colmatan progresivamente debido a la captura de una parte o la totalidad de sedimentos que los ríos transportan. La colmatación produce una serie de efectos tanto hidráulicos como ecológicos y socioeconómicos, como por ejemplo la pérdida de capacidad de almacenamiento de agua y de regulación de avenidas, el deterioro de los órganos de regulación de las presas (desagües de fondo, compuertas,…), la limitación del uso recreativo, y una mayor propensión a la eutrofia de la masa de agua, así como un déficit de sedimentos aguas abajo. Una solución a estos problemas es el vaciado total o parcial de embalses. Los vaciados de embalses planificados para la revisión del estado de conservación de las presas se muestran como una herramienta de gestión eficaz frente al problema de colmatación, aunque no libre de generar impactos sobre el sistema fluvial aguas abajo. Este trabajo analiza el balance de aguas y sedimentos en el río Segre durante el vaciado parcial del embalse de Sant Llorenç de Montgai a lo largo de 40 km aguas abajo de la presa. Para ello se realizó el monitoreo del caudal y del transporte de sedimentos en cuatro puntos de muestreo del río con el objetivo de estudiar la dinámica hidrosedimentaria durante el vaciado y estimar el balance de masas. Los caudales registrados durante el vaciado fueron similares a los registrados en crecidas ordinarias. Los resultados indican que la mayoría de los sedimentos movilizados y evacuados quedaron retenidos en azudes situados a distintas distancias aguas abajo de la presa. La carga sedimentaria registrada por debajo de estos azudes estuvo condicionada, en gran medida, por los sedimentos disponibles en el propio lecho del río Segre. Los resultados obtenidos subrayan la importancia de las diferentes infraestructuras (diques y azudes) ubicadas aguas abajo de la presa, con capacidad para modificar el transporte de sedimentos durante los vaciados y contribuir con ello a minimizar su impacto ambiental en el ecosistema fluvial. Estas infraestructuras, además, aumentan la disponibilidad de sedimentos para episodios de avenida posteriores con capacidad suficiente para re-suspender los sedimentos retenidos. Los resultados indican que una gestión más coordinada de las infraestructuras podría facilitar y optimizar el transporte de sedimentos en futuras actuaciones de vaciado del embalse.

ResumenEl artículo presenta un estudio cualitativo con nueve mujeres solteras profesionistas residentes de la zona metropolitana del Estado de México, sobre el significado que le otorgan al trabajo productivo y uso del ingreso económico y su expresión como transformación identitaria. Los resultados de las entrevistas y análisis de contenido revelan la transgresión a la pauta cultural tradicional de destinar el ingreso “para los otros”. Se discute que los significados otorgados al trabajo y uso del ingreso permiten generar autonomía en la toma de decisiones e incorpora el desarrollo personal y profesional. Se concluye sobre la necesidad de mostrar cambios en otros espacios para identificar permanencias y transformaciones en sus vidas.AbstractThe article presents a qualitative study with nine single professional women residents of the metropolitan area of the State of Mexico, on the meaning they give to productive work and use of their economic income and its expression as identity transformation.

ResumenEl objetivo de la presente investigación es identificar el efecto de la vestimenta de una mujer y el nivel de sexismo ambivalente que presenta el observador sobre la culpabilización de una víctima de violación sexual. Participaron 550 estudiantes de universidades privadas de México entre los 18 a 27 años. Se aplicó un cuadernillo con una fotografía de vestimenta (neutra, sexy, transgresora sexy y masculina), un escenario de violación sexual, preguntas para evaluar el efecto de la manipulación, el cuestionario de culpabilización (Romero-Sánchez, Megías y Krahé, 2012) y el ASI: Inventario de Sexismo Ambivalente (Glick y Fiske, 1996). El estudio muestra que la vestimenta aumenta o disminuye la culpabilización hacia la víctima por su relación con su nivel de sexismo.AbstractThe objective of the present investigation is to identify the effect of a woman's clothing and the level of ambivalent sexism presented by the observer on the blaming of a rape victim. Five hundred students from private universities in Mexico between the ages of 18 and 27 filled out a brief questionnaire. A booklet with a clothing photograph was applied (neutral, sexy, transgressor sexy and masculine), a rape scenario, questions to assess the effect of manipulation, the guilt questionnaire (Romero-Sánchez, Megías and Krahé, 2012) and the ASI: Inventory of Ambivalent Sexism (Glick and Fiske, 1996).  The study shows that attire increases or decreases the blame towards the victim for its relationship with their level of sexism.

El progresivo empoderamiento de la mulier frente a la violencia de género y las desigualdades=The progressive empowerment of the mulier against gender violence and inequalities
Authors: Catalán Elisa Muñoz
Published: June 2020

ResumenCon la realización del presente trabajo, pretendemos ofrecer un análisis jurídico de la legislación estatal vigente en materia de igualdad de género y no discriminación, las últimas reformas en Comunidades Autónomas como Andalucía, y los posibles retos, por tratarse de un derecho humano y fundamental. Se ha reparado en aquellos ámbitos donde se manifiestan las desigualdades entre hombre y mujer, y en los problemas que subyacen a los supuestos de violencia de género. Así como se ha profundizado en el papel que tradicionalmente ha desempeñado la mujer en la Historia, especialmente la mujer romana -mulier, uxor o materfamilias-, y su progresivo empoderamiento. Por tanto, abordar la necesaria igualdad de género puede resultar un punto de partida para futuros planes y políticas activas que ayuden a superar las trabas que aún existen.AbstractWith the completion of this work, we intend to offer a legal analysis of current state legislation on gender equality and non-discrimination, the latest reforms in Autonomous Communities such as Andalusia and possible challenges, as it is a human and fundamental right. Especially observed are those areas where inequalities between men and women are manifested, and in the problems underlying the assumptions of gender violence. As well as the role that women have traditionally played in History, especially Roman women -mulier, uxor or materfamilias-, and their progressive empowerment have been deepened. Therefore, addressing the necessary gender equality can be a starting point for future plans and active policies that help to overcome the obstacles that still exist.

AbstractDespite publishing houses recognizing the importance of ensuring equal representation of all people in curricular materials and scholars also noting their importance in teaching children gendered behaviours, it is still common to find stereotypically gendered non-coeducational curriculum materials in the international market. The aim of this study is to determine the representation of female and male characters in the illustrations of six colouring books published in the United Kingdom entitled “Books for Girls” and “Books for Boys”. A quantitative content analysis, and a supporting qualitative discourse analysis were carried out. This paper examines the effect of constructing gender difference in children’s colouring books. Gender bias in early childhood education poses the risk of perpetuating a manifestation of inequality.ResumenA pesar de que las editoriales reconocen la importancia de asegurar la representación igualitaria de todas las personas en los materiales curriculares y los académicos también señalan su importancia en la enseñanza de comportamientos de género a los niños, todavía es común encontrar en el mercado internacional materiales curriculares no coeducativos con estereotipos de género. El objetivo de este estudio es determinar la representación de los personajes femeninos y masculinos en las ilustraciones de seis libros para colorear publicados en el Reino Unido titulados “Books for Girls” y “Books for Boys”. Se llevó a cabo un análisis cuantitativo de contenido y de apoyo un análisis cualitativo del discurso. En el presente documento se examina el efecto de la construcción de la diferencia de género en los libros para colorear para la infancia. El sesgo de género en la educación infantil plantea el riesgo de perpetuar una manifestación de desigualdad.

The purpose is to show its main lines regarding how science and its production are understood, at a time when it seems clear that it is necessary to expand the subjects involved in the production of knowledge, as well as the importance of criticism as a tool for the improvement of scientific progress. For this purpose, the gender perspective and the voices that traditionally have not been part of this sphere of science, become essential to show gender biases in science.

ResumenEl objetivo del presente trabajo es revisitar la historiografía sobre género y ciencia, para pensar algunas claves desde dónde se mira el campo científico en clave de género en Argentina. Para ello, en primer lugar, se propone reconstruir en trazos generales las diferentes líneas de historia de la ciencia desde una perspectiva de género y las indagaciones realizadas en el campo. En segundo lugar, abordar los aportes que los estudios de género han realizado a la historiografía y, en especial, a la historia de la ciencia en Argentina. Por último, indagar algunas corrientes actuales que vinculan los estudios de la historia y de género, para proponer algunas líneas de análisis o puentes posibles del campo de estudio que expanda sus fronteras.  AbstractThe aim of the present work is to revisit the historiography on gender and science, to think about some keys from where the scientific field is looked at in terms of gender in Argentina.

“Saberes de Mujeres”: género, cambios generacionales y la construcción social de la salud=“Women’s wisdom”: Gender, generational changes and the social construction of health
Authors: Rosado Cárdenas Vivian Paulina , Pena Castro María Jesús
Published: June 2020

ResumenEn este artículo analizamos los principales discursos sobre los modelos de feminidad que son operativos en las comunidades u̩wotjü̩ja̩-piaroa (en la Amazonía guayanesa), colocando el acento en el peso simbólico de la menarquia en la construcción social de la salud, a partir de las narrativas de las mujeres contemporáneas. Indagamos en las múltiples interpretaciones del concepto isaju kju̩wo̩ju̩ (saberes de mujeres) para comprender los cambios generacionales y la diversidad constitutiva de la categoría genérica de “mujeres”. Para esto, damos cuenta de lo que representa “ser” hombres y mujeres en la actualidad de las aldeas, los requisitos necesarios de acceso a la adultez y el papel de la ontología en la construcción contemporánea de las escalas de valor social.AbstractIn this paper we analyze the main discourses on the models of femininity that are operative in u̩wotjü̩ja̩-piaroa communities (in the Guyanese Amazon area), emphasizing the symbolic weight of menarche in the social construction of health, based on the narratives of contemporary women. We focus on the concept isaju kju̩wo̩ju̩ (women's wisdom) and its multiple interpretations to understand the generational changes and the great diversity that constitutes the category "women". For this purpose, we describe what to "be" men and women means in the villages today; the necessary requirements for access to adulthood; and the ontology relevance in the contemporary construction of social value scales.
The inhibitors of the apical sodium-dependent bile acid transporter (ASBT) as promising drugs

Inhibition of the apical sodium-dependent bile acid transporter (ASBT, also known as IBAT — ileal bile acid transporter, SLC10A2) leads to disruption of the enterohepatic circulation of bile acids and their excretion with fecal masses. This is accompanied by cholesterol utilization for synthesis of new bile acids. ASBT inhibitors are promising drugs for the treatment of such diseases as non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, type 2 diabetes mellitus, necrotic enterocolitis, chronic constipation, atherosclerosis. To date the most known chemically synthesized inhibitors are: A3309, SHP626, A4250, 264W94, GSK2330672, SC-435. All of them are at different stages of clinical trials, which confirm the high efficacy and good tolerance of these inhibitors. Current trends in this field also include directed chemical synthesis of ASBT inhibitors, as well as their search among substances of plant origin.
Molecular mechanisms of action and physiological effects of the proinsulin C-peptide (a systematic review)
Authors: Poteryaeva O.N. , Usynin I.F.
Published: June 2020

The C-peptide is a fragment of proinsulin, the cleavage of which forms active insulin. In recent years, new information has appeared on the physiological effects of the C-peptide, indicating its positive effect on many organs and tissues, including the kidneys, nervous system, heart, vascular endothelium and blood microcirculation. Studies on experimental models of diabetes mellitus in animals, as well as clinical trials in patients with diabetes, have shown that the C-peptide has an important regulatory effect on the early stages of functional and structural disorders caused by this disease. The C-peptide exhibits its effects through binding to a specific receptor on the cell membrane and activation of downstream signaling pathways. Intracellular signaling involves G-proteins and Ca2+-dependent pathways, resulting in activation and increased expression of endothelial nitric oxide synthase, Na+/K+-ATPase and important transcription factors involved in apoptosis, anti-inflammatory and other intracellular defense mechanisms. This review gives an idea of the C-peptide as a bioactive endogenous peptide that has its own biological activity and therapeutic potential.
Telomerase activity, mTert gene expression and the telomere length in mouse mesenchymal stem cells in the late period after γ- and γ,n-irradiation and in the tumors developed from these cells

In proliferating normal and tumor cells, the telomere length (TL) is maintained by high telomerase activity (TA). In the absence of TA the TL maintenance involves a mechanism of alternative lengthening of telomeres (ALT). The aim of this study was to investigate the level of TA, the mTert expression and TL in cultured normal and transformed by γ- and γ,n-irradiation mesenchymal stem cells (MSCs) from mouse bone marrow, in sarcomas that developed after the transplantation of these cells into syngeneic mice, and in fibrosarcoma cell lines obtained from these tumors to find out the role of AT or ALT in maintaining TL in these cells. During prolonged cultivation of normal and transformed under the influence of γ- (1 Gy and 6 Gy) and γ,n-irradiation (0.05 Gy, 0.5 Gy, and 2 Gy) MSCs from mouse bone marrow, a decrease in TA was detected in irradiated cells. Even deeper decrease in TA was found in sarcomas developed after administration of transformed MSCs to syngeneic mice and in fibrosarcoma cell lines isolated from these tumors in which TA was either absent or was found to be at a very low level. TL in three of the four lines obtained was halved compared to the initial MSCs. With absent or low TA and reduced TL, the cells of all the obtained fibrosarcoma lines successfully proliferated without signs of a change in survival. The mechanism of telomere maintainance in fibrosarcoma cell lines in the absence of TA needs further investigation and it can be assumed that it is associated with the use of the ALT. The detected decrease or absence of TA in transformed under the action of irradiation MSCs with the preservation or even an increase in the telomerase gene expression may be associated with the formation of inactive splicing variants, and requires further study. The obtained lines of transformed MSCs and fibrosarcomas with TA and without the activity of this enzyme can be a useful model for studying the efficacy of TA and ALT inhibitors in vitro and in vivo.
A prospective study of acceptability, safety and demographic profile for post placental intrauterine contraceptive device
Authors: Jain Neha , Choudhari Hemangi K.
Published: June 2020

Background: The objective of this study was to study the acceptance rate, safety, demographic profile and complication of post placental intrauterine contraceptive device (PPIUCD).Methods: Study was prospective, interventional study, held in department of Obstetrics and Gynaecology at authors tertiary care centre.  Number of participants was 280. Counselling about family planning was done in antenatal OPD and indoor ward. Total duration of study was 18 months. Selection of participants done based on selection criteria. Participants who accepted postplacental   intrauterine contraceptive device as method of contraception followed up to 6 weeks postnatal for complication related to PPIUCD.Results: Authors noted that acceptance rate of PPIUCD was 13.6% and main reason for acceptance was its long acting reversible nature and main reason for denial was ‘do not want contraception immediately’. In present study there was statistically significant association between parity and birth order. However, literacy, urban locality and employment had positive influence over acceptance.  If good technique of insertion will be used than expulsion rate will also reduce as seen in present study i.e. expulsion rate only 2.6 %.Conclusions: Post placental intrauterine contraceptive device is one of the best long acting reversible contraceptive methods. It does not affect breast milk production. Woman does not need extra visit to clinic for contraception and she is ensured that she has adequate contraception before getting discharge from hospital. PPIUCD provide adequate birth spacing between two children which reduces maternal and child morbidity.
