Authors: Скачков Владимир Михайлович , Пасечник Лилия Александровна , Яценко Сергей Павлович
Published: December 2020

В статье обсуждается возможность регулирования свойств диффузионнотвердеющего припоя (ДТП) на основе легкоплавкого сплава галлий-олово и твердой компоненты состоящей из порошка сплава медь-олово посредством введения инертного порошка металлического молибдена и термической обработки. Оценена микротвердость и термическая устойчивость композиционных диффузионнотвердеющих припоев. Показано, что повторная термическая обработка при высоких температурах способствует переходу припоя в равновесное состояние, при этом происходит резкое увеличение твердости, почти на порядок. Подтверждено, что инертные наполнители снижают механическую прочность относительно начального диффузионно-твердеющего припоя, даже те, которые хорошо смачиваются галлием, однако существует некий диапазон, содержащий определенное количество инертного компонента, у порошка молибдена это 15 %, при котором микротвердость композиционного припоя выходит на максимум.

The article discusses the possibility of regulating the properties of a diffusion-hardening solder based on a low-melting gallium-tin alloy and a solid component consisting of a copper-tin alloy powder by introducing an inert metal molybdenum powder and heat treatment. The microhardness and thermal stability of composite diffusion-hardening solders were evaluated. It is shown that repeated heat treatment at high temperatures contributes to the transition of the solder to an equilibrium state, with a sharp increase in hardness, almost by an order of magnitude. It is confirmed that inert fillers reduce the mechanical strength relative to the initial diffusion-hardening solder, even those that are well wetted with gallium, but there is a certain range containing a certain amount of the inert component, for molybdenum powder it is 15 %, at which the microhardness of the composite solder reaches the maximum.

Authors: Хуболов Борис Магометович
Published: December 2020

Химическим анализом установлено, что при электрохимическом восстановлении в расплавах MWO -WO (M - Li, Na, K, Cs,Tl) образуются оксидные вольфрамовые бронзы различного состава и структуры. Изучена зависимость изменения равновесных потенциалов катодных продуктов от температуры и состава расплава. Установлено, что с увеличением содержания щелочного металла в вольфраматных расплавах число зародышей кристаллов уменьшается. Снижение температуры расплава и увеличение катодной плотности тока также приводит к уменьшению размеров зерен катодных осадков, что позволяет получать порошки оксидных вольфрамовых бронз контролируемой дисперсности. Методами рентгеноэлектронной спектроскопии и каналирования были исследованы структура конденсированных в среднем вакууме тонких пленок, а также монокристаллы натрийвольфрамовых бронз электрохимически циклированных в анодном и катодном режимах для получения информации о толщине окрашивающего слоя.

Chemical analysis established that during electrochemical reduction in MWO - WO (M - Li, Na, K, Cs,Tl) melts, tungsten oxide bronzes of various compositions and structures are formed. The dependence of the change in the equilibrium potentials of cathode products on the temperature and composition of the melt has been studied. It was found that with an increase in the content of alkali metal in tungsten melts, the number of crystal nuclei decreases. A decrease in the melt temperature and an increase in the cathode current density also lead to a decrease in the grain size of the cathode deposits, which makes it possible to obtain powders of tungsten oxide bronzes of controlled dispersion.

Данная работа посвящена исследованию влияния типа полимерной матрицы сверхсшитого полистирола на активность и стабильность палладиевых катализаторов кросс-сочетания Сузуки. Показано, что применение сверхсшитого полистирола, функционализированного третичными аминогруппами, может быть перспективным с точки зрения обеспечения стабильности катализатора при рециклах, однако для достижения 100 % конверсии арилгалогенида (4 - броманизола) требуется применение сильного избытка фенилбороновой кислоты и основания. Катализатор на основе нефункционализированного сверхсшитого полистирола обладает более высокой активностью и позволяет, используя полуторакратный избыток фенилбороновой кислоты, достичь полной конверсии 4 - броманизола за 60 мин реакции в мягких условиях (70 °С, растворитель - смесь этанола и воды в соотношении 5:1). Недостатком такой системы является сильная адсорбция продукта кросс-сочетания в гидрофобной полимерной матрице.

This work is devoted to the study of the influence of the type of polymeric matrix of hyper-crosslinked polystyrene on activity and stability of palladium catalysts of Suzuki cross-coupling. The use of the hyper-crosslinked polystyrene functionalized with tertiary amino groups was shown to be promising in terms of ensuring of the catalyst stability during recycles, but in order to achieve 100 % conversion of aryl halide (4 - bromanisole) the use of strong excess of phenylboronic acid and of a base is required. The catalyst based on non-functionalized hyper-crosslinked polystyrene had higher activity and allowed achieving complete conversion of 4 - bromanisole during the reaction under mild conditions (70 °C, ethanol and water mixture is in the ratio of 5 : 1 as a solvent) while using 1,5 - fold excess of phenylboronic acid. However, strong adsorption of the cross-coupling product in a hydrophobic polymeric matrix was found to be a disadvantage of such a system.

Published: December 2020

Ионная имплантация ионами отдачи или ионное перемешивание, основанное на внедрении требуемой примеси из поверхностных слоев при передаче им кинетической энергии первичного пучка, имеют большие перспективы для получения структур и соединений с заданными свойствами. В процессе масштабирования сверхбольших интегральных схем паразитное сопротивление межсодинений и неомический характер контактов являются ограничивающими факторами. Перспективными материалами для использования в системах металлизации являются силициды тугоплавких металлов. В работе проведено исследование по внедрению ионов фосфора в систему молибден-кремний. Полученные результаты демонстрируют возможность формирования силицида молибдена при пониженной температуре, применением имплантации ионов, вызывающих ионное перемешивание. Разработанная технология позволяет достичь однородной границы раздела силицида с кремнием, и необходимые электрофизические характеристики метализации и омических контактов. Из-за заглубления границы раздела в объем полупроводника снижается влияние состояния поверхности кремния на параметры омических контактов, в результате обеспечивается их необходимая стабильность и воспроизводимость.

Ion implantation with recoil ions or ion mixing based on the introduction of the required impurity from the surface layers during the transfer of the kinetic energy of the primary beam to them have great prospects for obtaining structures and compounds with desired properties. In the process of ranging of very large scale integrated circuits, the parasitic resistance of interconnections and the nonohmic nature of contacts are the limiting factors. Refractory metal silicides are promising materials for use in metallization systems. In this work a study was carried out on the introduction of phosphorus ions into molybdenum-silicon systems. The results obtained demonstrate the possibility of the molybdenum silicide formation at a low temperature using implantation of ions that cause ionic mixing. The developed technology makes it possible to achieve a homogeneous interface between the silicide and silicon with the necessary electrophysical characteristics of metalization and ohmic contacts. Due to the deepening of the interface into the bulk of the semiconductor, the effect of the silicon surface state on parameters of ohmic contacts decreases. As a result their necessary stability and reproducibility are ensured.

Published: December 2020

Violence behaviour is a maladaptive form of anger response that is dangerous and can hurt yourself, others and the environment. Therefore it is a concern for health workers to apply an effective and appropriate therapy to overcome these problems. This study was aimed to compare the differences in Cognitive Behavior Therapy (CBT) and Assertive Training (AT) in controlling violent behavior in schizophrenic patients.This study was used a quasi experimental pre-post test control group design.The number of samples was 30 respondents and taken by purposive sampling technique based on inclusion criteria. Samples of this study were schizophrenic patients with violent behavior totaling 30 people consisting of 10 people in the treatment group I who were given a standard of nursing care and CBT,10 people in the treatment group II who were given a standard of nursing care and AT and 10 people in the control group who only got the standard nursing behavior violent behavior.The results showed that there were differences in the patient's violent behavior between the treatment groups given CBT, AT and the control group before and after the intervention was given with CBT p=0.021 and ATp =0.032.There was a significant difference between CBT and AT in controlling violent behavior with a value of p=0.015. Based on the mean difference values, CBT have been better than AT in controlling violent behavior. CBT can improve patient's ability to control violent behavior. We recommend that CBT can be applied in health and community services.

Published: December 2020

O artigo analisa alguns aspectos sobre a história dos cursos normais regionais de formação de professores primários rurais pelo estado do Maranhão, Brasil. Com a sistematização de dados estatísticos produzidos pelo INEP/MEC entre 1949 e 1960, foi possível verificar a implantação de Escolas Normais Regionais/Rurais no Maranhão a partir da segunda metade dos anos 1950. Constatou-se, porém, que a lenta difusão de escolas com curso normal regional ficou restrita ao setor privado, nas regiões noroeste e centro-sul do estado. A Igreja Católica, por meio de congregações religiosas, ofertou a formação do magistério primário rural maranhense, com contrapartidas legais e financeiras do poder público.

Published: December 2020

El presente estudio analiza las condiciones y posibilidades de permanencia del programa “Salud al Paso” de la Secretaría Metropolitana de Salud del Municipio de Quito, Ecuador, como ejemplo para iniciativas similares, en el contexto de los cambios efectuados por la nueva administración en mayo del 2019. El análisis de esta implementación enfocada en la prevención de enfermedades no transmisibles se centró en la base de datos de usuarios del programa, la información recabada desde las perspectivas del personal operativo, el conocimiento del programa y el posicionamiento de líderes locales y de opinión del Distrito Metropolitano de Quito, así como información oficial. Con base en estos datos, el estudio identificó factores que podrían haber facilitado u obstaculizado su permanencia y documentó la fundamentación de las nuevas autoridades para suspender las actividades de libre demanda propias del programa y limitar la atención a las poblaciones bajo responsabilidad municipal (guarderías, escuelas y colegios, mercados, programas de atención a la tercera edad y empleados) y de pacientes con riesgo cardiometabólico identificado. La institucionalización insuficiente del programa, concebido más como proyecto y con una también insuficiente visión de permanencia en el tiempo, fue mencionada como un posible obstáculo por líderes y personal operativo. La prevalencia creciente de enfermedades no transmisibles demanda iniciativas para su prevención, que deben institucionalizarse para asegurar su continuidad y superar eventuales cambios de gobierno. Además, intervenciones futuras semejantes a Salud al Paso deberán establecer una mejor articulación sectorial, en especial con el Ministerio de Salud Pública y otras redes de servicios.

Published: December 2020

Fraser (1988; 1996; 1999) which are classified EDMs functions as ‘contrastive, ‘elaborative, and ‘inferential. This study designated the use of English discourse markers by University EFL students in writing production. To answer the research question on how do they disclose EDMs in producing writing, the writers employed a qualitative research approach. The object was the documentation of students’ writing result mediated on the writing class. The participants were 38 students of semester III in the academic year 2018/2019. The findings are the contrastive markers are; but 63/instead of 2/whereas 2/however 16/although 2/in the other hand /side 6. The elaborative markers are; and 597/also 105/or 69/for example 27/besides 7/moreover 3/in addition, 24/then 6/likewise 1. The inferential markers are; because 97/so 51/as a result 9/therefore 11/in conclusion 3/then 1. The most functions of discourse markers use by students are; the marker ‘but’ has a meaning ‘on the contrary. The marker ‘and’ has a meaning as ‘in addition’. Students used the marker ‘because’ to indicate ‘for the reason’. The implication of this study is that students need to understand in employing properly English discourse markers to make their writing being cohesive and coherent in texts.

Published: December 2020

Teacher observation is an important but underutilized assessment technique. It is sometimes argued that teachers are unable to make appropriate and dependable assessment judgments from observations of students in natural settings. Handled carefully, teacher observations can provide important evidence for assessment judgments. In some cases, they provide the only way of obtaining evidence about particular learning outcomes, especially those involving practical techniques, performance activities, ‘real life’ projects and group work.
GEORGI PIRINSKI SR. AND THE AMERICAN SLAV CONGRESS
Authors:   Russian State University for the Humanities, Zaitsev Aleksandr V.
Published: December 2020

Georgi Pirinski Jr. is a prominent Bulgarian politician. He was Minister of Foreign Affairs and Chairman of the National Assembly. This article regards his father, Georgi Pirinski Sr., who was the Executive Secretary of the American Slav Congress (1944–1951) and Chairman of the Bulgarian Committee for Peace (1969–1972). An émigré from Bulgaria, he took a pseudonym in memory of his native land – the Pirin Macedonia. Rather soon, Pirinski became a prominent trade union leader. His influence on the situation in the world was the greatest, when he was actually the leader of the largest all-Slavic organization in America – the American Slav Congress (the ASC). As an executive secretary of the ASC, Pirinski Sr. determined the American and foreign policy of the organization; in particular, he spoke on behalf of the ASC from the rostrum of the US Congress. Being an illegal member of the Communist Party of the USA, he pursued a pro-Soviet policy inside the ASC which contributed to the schism and abolishment of the ASC; he himself after several arrests had to return to Bulgaria. At the end of his life he felt regret for his fanaticism. Looking at the career of his son, one would say that Georgi Pirinski Jr. learnt from his father’s mistakes and became so successful as a politician that he had to be stopped by semi-legal means.
HISTORICAL AND DOCUMENTARY HERITAGE OF THE GREAT PATRIOTIC WAR. TOWARDS THE HISTORY OF THE DOCUMENTS COLLECTING
Authors:   Russian State University for the Humanities, Khorkhordina Tatyana I.
Published: December 2020

Basing on the archival sources of the GARF and RGAE, the article analyses the stages of collection and usage of the documentary heritage of the Great Patriotic War. It was at the very beginning of the Great Patriotic War that the decision was made to collect the war-time records. It is noted that various institutions and organizations were involved in the process of accumulating such documentary heritage including the Commission on History of the Great Patriotic War at the Academy of Sciences of the USSR which developed into the methodological centre coordinating the work of local commissions. Under war-time conditions, the state archives acquisition techniques and methods made it necessary to introduce significant changes into the collecting procedures of the State Archival Fund. The paper discusses the initiatives and measures taken by the State Archives Administration for the acquisition of archives with the war-time documents. The article analyses the reports and speeches of the delegates of the All-Russia Conference of Historians and Archivists, held in June 1943, at which the issue of collecting various types and kinds of the documentary evidence of the Great Patriotic War was raised, and among that evidence – the documents of personal origin: the letters, diaries, memoirs of ordinary participants in the events. Proposals were put forward and the resolution was adopted concerning the foundation of the Central State Archives of the Great Patriotic War, what, however, was not implemented. The idea of establishing a special Archives, promoted by the Conference, was revived in the 1970s by Konstantin Simonov, the writer, whose actions still did not result in the creation of the institution. Using archival sources, the article considers the work of the staff members of the state archives and museums, and also of the academic staff and the students of the Moscow Institute for History and Archives referring to their activities such as the collection and preservation of the documentary heritage of the Great Patriotic War.

Aims: Q-LAMP aims to identify risk factors and resilience factors for symptoms of psychiatric illness during the pandemic. Study strengths include the 1-year longitudinal design and the use of standardized instruments already available in English and Arabic. The results will increase understanding of the impact of the pandemic on mental health for better support of the population during the pandemic and in future epidemics. Until an effective vaccine is available or herd immunity is achieved, countries are likely to encounter repeated ‘waves’ of infection. The identification of at-risk groups for mental illness will inform the planning and delivery of individualized treatment including primary prevention. Methodology: Longitudinal online survey; SMS-based recruitment and social media platforms advertisements e.g. Facebook, Instagram; Online consent; Completion time for questionnaires: approx. 20 to 30 minute; Baseline questionnaire with follow up at 3, 6, 9 and 12 months; Study completion date: Sept. 2021. Inclusion criteria: Currently living in Qatar; Qatari residents: citizens and expatriates; Age 18 years; read Arabic or English (questionnaire and consent form available in both languages). Instruments: Sociodemographic questionnaire including personal and family experience of COVID-19 infection; Standard instruments to assess psychiatric morbidity including depression, anxiety and PTSD; research team-designed instruments to assess social impact of pandemic; standard questionnaires to assess resilience, personality, loneliness, religious beliefs and social networks. Results: The analysis was based on 181 observations. Approximately, 3.5% of the sample was from the sms-recruitment method. The sample of completed surveys consisted of 65.0% females and 35.0% males. Qatari respondents comprised 27.0% of the total sample, while 52% of the sample were married, 25% had Grade 12 or lower level of educational attainment, and 46.0% were unemployed. Covid-19 appears to have affected different aspects of people’s lives from personal health to living arrangements, employment, and health of family and friends. Approximately, 41% to 55% of those who responded to the survey perceived changes in their stress levels, mental health, and loneliness to be worse than before the pandemic. Additionally, the wide availability of information about the pandemic on the internet and social media was perceived as source of pandemic-related worries among members of the public. Conclusion: The continued provision of mental health service and educational campaigns about effective stress and mental health management is warranted.

Authors: Fatima Tahniyath , Elbanna Saïd
Published: December 2020

Performance management research in the hospitality industry remains stagnant despite prevalence of multi-dimensional performance metrics. This study, thus, contributes to the hospitality industry and sustainability literature through developing a semi-hierarchical sustainability balanced scorecard scale considering the COVID-19 impact on the hospitality industry. As the Indian travel and tourism industry ranks in the bottom 20%-40% on health and hygiene and environment sustainability, this research study’s setting, India, holds particular importance. Upon analyzing 200 questionnaires and five in-depth interviews from 4- and 5- star hotels in India through three-stage multi-method design of scale development, we proposed a scale of 21 indicators factored into six perspectives. A post hoc analysis added a new health and safety perspective to consider the impact of COVID-19 pandemic on the hospitality industry and its endeavor to explore a road to recovery by stressing employee and tourist health and well-being. Implications from the study findings are also discussed

Due to the current COVID situation, there’s a huge need for crowd control as well as efficient social distancing. Security cameras are everywhere but personnel to monitor it are few. In this project, we use crowd counting and detection along with social distancing monitoring which would enable efficient social distancing and control of the crowd intelligently. The lightening of the cumbersome task of the security professionals to monitor and analyze the crowd is done here making smart decisions on their behalf. In addition, masks are essential instruments to prevent a Corona infection; they are essentials for every individual in a crowd. In this project non-facemask wearing people can be detected at public places and an alert send for that particular individual which further helps control COVID infections. Intelligent system achieved by these two tasks will enable informed decision-making, efficient remote monitoring of crowd, proper social distancing and thus achieving safety at essential infrastructures like transport stations, schools, malls, airports, playground, hospitals etc. where tracking multiple cameras at the same time would be a hassle for security professionals. In this project, we propose a deep learning approach to accurately detect crowd above a certain restriction and make sure the individuals abide by wearing masks and social distancing effectively.

The purpose of this study was to evaluate the dietary habits (DH) and eating behaviors (EB) among adults during COVID-19-induced confinement. For this purpose, an online survey designed to assess the change in DH and EB during April and May of 2020 was distributed using various social media platforms. A total of 1844 participants aged 18-72 years completed the survey. The results outlined an increase (42.5-61.8%) in most of the DH and EB examined in the current study in the majority of the participants. Among these changes, increased (p<0.05) prevalence of fruit and vegetable, immune boosters, water, and hot beverage consumption as well as decreased (p<0.05) eating in restaurants and fatty food consumption, suggest a positive change. Conversely, a greater (p<0.05) percentage of the participants reported an increase in high-calorie food consumption and late night eating indicating a risky behavior for obesity and subsequent chronic complications. Additionally, age, gender, obesity, education, income, and job type seem to contribute (p<0.05) to the changes in DH and EB. Overall, COVID-19-induced confinement seems to compel adults to adopt a specific DH and EB. Though most of these changes were positive, some were negative. The study provides crucial information to design subpopulation recommendations and developmental programs for adults under such conditions.

Published: December 2020

Penelitian ini bertujuan untuk mengetahui pola komunikasi keluarga cerai dalam membina perilaku anak. Jenis penelitian yang digunakan menggunakan pendekatan kualitatif dengan metode deskriptif. Data yang dibutuhkan dalam penelitian ini merupakan data kualitatif sebagai data primer berupa gambar, katakata dan bukan angka-angka dalam sebuah wacana mengenai pola komunikasi keluarga cerai dalam membina perilaku anak. Berdasarkan hasil penelitian diperoleh hasil bahwa pola komunikasi yang berada di keluarga cerai cenderung tidak efektif. Pasca-cerai interaksi antara orangtua dan anak tidak akan seintents saat keluarga utuh karena kurang dibangunnya komunikasi anatara anak dan orangtua. Tetapi hal ini dapat diubah dengan membentuk pola komunikasi empatik significant others dari single mother atau single father untuk memberikan pemahaman positif bagi anak. Tujuan pola komunikasi tersebut untuk membangun kembali konstruksi konsep positif diri pada anak. Sehingga permbinaan perilaku pada anak dapat lebih mudah untuk dilakukan.

Dress ethics is an important factor that is accounted for by an individual in a community. Someone will judge us by our appearance including our dress code. In the library there are regulations regarding the prohibition of using sandals, T-shirts and must be neatly dressed which raises the arena of social class and identity. By using the Ethnographic approach we can understand a social and cultural life in a society scientifically. In this case, we consider the views of the people as the most important thing. The results of this discussion criticize things that should not be taken for granted and open the knowledge of librarians to think critically in managing a library as a source of information
Penggunaan Literatur dalam Penulisan Karya Ilmiah Mahasiswa Agroteknologi Instiper Yogyakarta (Studi Bibliometrika pada Jurnal Agromast Tahun 2018-2019)

Published: December 2020

This study aims to determine the dominance of reference sources, types of references, the most cited authors, the availability of collections in the Stiper Institute of Agriculture (Instiper) library and the reference year used by students in preparing scientific papers. This study uses a quantitative descriptive approach and bibliometric studies with citation analysis and literary life half-life. The object of analysis in this research is 166 scientific articles published in the journal Agromast published in 2018-2019. The results showed that: 1) types of reference sources or information materials used as references for students in writing scientific papers were dominated by types of references in the form of books (74.90%) and scientific articles (16.10%). 2) The half-life age of the literature cited in the journal Argomast as a whole from 2018 to 2019 is 8 years. 75.59% of the literature that is considered up-to-date or obsolete, while the literature that is considered current is 28.15%. Thus, the literature used as a reference in the Agromast journal 2018-2019 tends to use less up-to-date literature.
Influence of Land Use and Rainfall on Carbon Stock Dynamics for Oil Palm and Rubber

Published: December 2020

The expansion of agricultural commodities including oil palm plantations potentially causes an increase of greenhouse gas emissions by amplifying carbon dioxide (CO2) in the atmosphere. In the long term, this amplification will alter climate change. However, oil palm also has the potency to reduce greenhouse gas emissions by absorbing CO2 through photosynthesis. This study aims to determine the carbon stock that can be absorbed by oil palm and rubber plants, and to determine the relationship of rainfall with carbon stock in oil palm plants. The study used satellite image data based on Landsat and combined with rainfall data from near Perbaungan District, North Sumatra.  Three Landsat data (acquisition date: (i) 12 February 2000, (ii) 8 March 2009, and (iii) 11 August 2019) were processed to estimate carbon stock. The procedure for estimating carbon stock was as follows: determining the sample and digitizing the sampling points, converting the digital value of the numbers into the spectral spectrum, calculating the albedo values, calculating the long-wave and short-wave radiations, computing biomass, and the absorbed carbon stock. The results showed that the carbon stock in oil palm was greater than that of rubber plants as oil palm has a greater biomass. The greater the plant biomass, the bigger the carbon stock absorbed. Further, the findings revealed that rainfall in dry season has a contribution to carbon stock in oil palm and rubber. The higher the total rainfall during dry season will increase the absorbed carbon stocks.

Papa Francisco: um sinal de contradição?

Published: December 2020

A aproximação e melhor acolhida eclesial à comunidade LGBT, materializadas nas palavras e, sobretudo, nos gestos do Bispo de Roma, é o foco deste artigo. Seu principal objetivo é analisar os grupos LGBT a partir dos ensinamentos/posturas pastorais do Papa Francisco e a oposição explícita que ele tem enfrentado por parte de seguimentos tradicionalistas da Igreja. Pretende-se evidenciar a presença e a força atuais da comunidade LGBT como um fato histórico, social e político, que interpela a Igreja e que deve ser lido numa perspectiva teológica. Por meio da pesquisa bibliográfica e a partir das categorias “sinais dos tempos”, “sinal de contradição” e “periferias existenciais” busca-se ponderar sobre alguns dos maiores desafios e oportunidades que tal conjuntura oferece para uma efetiva escuta, reconhecimento e acolhida das pessoas LGBT no seio eclesial. Trata-se, portanto, de um texto de teologia elaborado em diálogo com outras ciências que auxiliam na decodificação do objeto, servindo-se de fontes do Magistério e de estudos atuais sobre os sujeitos LGBT.
O corpo cristão como corpo feminino

Published: December 2020

Através da análise da terceira carta de Heloísa a Abelardo, inserida no contexto maior da discussão da correspondência pessoal e na discussão filosófica/teológica que perpassa a obra do palatino, percebese que há uma tríplice possibilidade de leitura: a primeira, relacionada diretamente com o conteúdo da carta, critica o ambiente monástico feminino do século XII; a segunda, inserindo-se no contexto da correspondência pessoal, permite a descoberta de um fio condutor na discussão de todas as cartas de Heloísa, apesar da aparente ruptura temática entre a segunda e a terceira carta; a terceira, insere o corpo feminino como o ponto de partida da experiência pessoal cristã de Heloísa, e por isso serve de contestação ao modelo de corpo como algo “desprezível e rejeitado”, conforme a proposição inicial de Pedro Abelardo.

Published: December 2020

This article presents the results for flow past a square cylinder and two square cylinders of the same and different sizes with corner modifications by varying the spacing ratio. Here, experimental work is conducted in a recirculatory channel filled with water. A set of aluminum discs made to rotate to create the flow in the test section. The motor is used to vary the speed of the water. Fine aluminum powder is used as a tracer medium. It is observed that vortex shedding frequency decreases by placing the second cylinder in the downstream of the first cylinder. For similar size cylinders, the width of the eddy in the middle of the cylinders increases with an increase in spacing ratio. With the increase of spacing ratio to 6, the flow past each cylinder behaves like a single square cylinder. If the upstream square cylinder size is smaller than the downstream square cylinder, the eddy size is reduced in between the cylinder compared to the downstream of the second cylinder. If the upstream square cylinder size is bigger than the downstream square cylinder, the eddy size is larger in between the cylinder compared to the downstream of the second cylinder.
