Published: December 2021

Background: Egypt has a shortage of physicians despite thousands of medical students graduating annually. Aims: This study aimed to explore the reasons for Egyptian medical students and young physicians wanting to emigrate. Methods: This cross-sectional study, conducted from February to April 2019, included 711 fifth- and sixth-year medical students and 174 residents from two medical faculties in Egypt, Tanta and Kafrelshiekh. A questionnaire was used to collect data on sociodemographic factors, desire to emigrate and motives for wanting to emigrate. Results: Most participant (89.4%) wanted to emigrate, and thought their salary was not compatible with their working hours or risks. About half the participants (52.8%) worked part-time in private hospitals. Only 4.9% of participants felt appreciated by the country. Most participants (75.9%) were not satisfied with their relationship with patients and 40.2% were not satisfied with their relationship with colleagues. Verbal abuse was reported by 55.5% of participants and physical assaults by 35.4%. Most participants who wanted to emigrate (85.1%) said they would change their minds if improvements were made in the health sector. Residents generally had less negative attitudes to workplace and professional factors than students. Conclusion: Physicians emigrate to seek better work and financial incentives. A retention policy needs to be developed to prevent Egyptian physicians from emigrating

Published: December 2021

Background: Little is known about the role of occupational-related physical activity and risk factors for cardiovascular disease. Aims: This study aimed to assess the association between different types of physical activity (work-related, transport-related, home-time and leisure-time) and risk factors for cardiovascular disease in a sample of Iranian workers. Methods: This cross-sectional study was conducted from February to November 2018 among 415 workers of a rubber factory in Tehran province. Physical activity levels of the participants were measured using the International Physical Activity Questionnaire. Blood sample were analysed for cardiovascular disease risk factors (fasting blood sugar ≥ 100 mg/dL, triglycerides ≥ 150 mg/dL, total cholesterol ≥ 200 mg/dL, systolic blood pressure ≥ 130 mmHg, diastolic blood pressure ≥ 85 mmHg and waist circumference ≥ 102 cm). Alanine aminotransferase and aspartate aminotransferase were also measured, as was body mass index (BMI). Results: Risk factors for cardiovascular disease differed significantly according to type of physical activity. Fasting blood sugar ≥ 100 mg/dL and BMI ≥ 25 kg/m2 had a significant negative association with overall physical activity level (P < 0.001). In a logistic regression analysis, leisure-time physical activity had a significant negative correlation with all risk factors for cardiovascular disease after adjusting for age and smoking. Conclusion: Leisure-time physical activity has a more important role in reducing cardiovascular disease risk factors than other types of activity, including work-related physical activity.

Numerous studies have proved the necessity of egg yolk in synthetic media to dilute semen before its cryopreservation. However, at the same time, it has been demonstrated that its use can adversely affect the quality of frozen-thawed sperm. The present study compares the main quality parameters of ram sperm frozen using TRIS-based diluent with egg yolk and two egg yolk-free diluents (OvixCell® and AndroMed®). A slower deterioration in the kinematic performance of sperm cryopreserved in TRIS diluent with native egg yolk confirmed higher cryoprotective performance compared to commercial extenders containing no egg yolk. Significantly higher total and progressive motility was observed in TRIS-based medium with egg yolk (P< 0.05). This advantage was maintained after four hours of incubation and became more significant at the end of cultivation (after six hours) (P< 0.01). Thus, ram sperm frozen in egg yolk medium retained better motility than in egg yolk-free extenders, which allows predicting its higher bioavailability. Assessment of some semen parameters using CASA showed that there were no significant differences in motility between the three extenders immediately after thawing the straws. When assessed two hours after thawing, a diluent containing egg yolk (TRIS-based) was found to have higher results for some of the examined traits than phospholipid diluents.
Daily variations in tomato stem diameter as a criterion for irrigation management

Published: December 2021

The process of daily variation in tomato stem diameter is examined in order to justify the use of this parameter to control drip irrigation. Changes in the size of individual plant parts depend on the provision of water, light, heat and nutrients to the production process. Therefore, such plant parameters as leaf temperature, xylem ﬂow rate, fruit and stem diameter can be indicators of availability of necessary resources. The research was carried out in Novosibirsk region in June - September 2020. The value of the range of daily variations in stem diameter, which has a close relationship to relative soil moisture, was used as an indicator of plant water stress. The source of the information is the results of measurements of soil moisture and stem diameter growth of tomato. Experiments to assess the eﬀect of water deﬁcit on stem parameters were carried out on a plant set out in the open ground separately from the rest. Artiﬁcial water stress conditions were created by watering once a week. Data were collected using a PM-11z phytomonitor, soil moisture and stem diameter growth sensors. The results of measurements were processed in Microsoft Oﬃce Excel program. It was found that the range of daily ﬂuctuations of stem diameter growth depends on moisture availability. When soil moisture is below 30%, the plant experiences water stress and the range of stem diameter ﬂuctuations increases. The maximum growth in stem diameter was observed at 7-10 a.m. and the minimum at 13-15 p.m. local time. The diﬀerence between the maximum and minimum of the daily stem diameter increase characterizes the range of the daily stem diameter diﬀerence, which correlates closely with soil moisture. The correlation coeﬃcient between them is 0.72. The limit for the daily stem diameter diﬀerence is 0.025 mm at 30% soil moisture. If the actual value of this parameter exceeds the limit value, the irrigation system can be activated. The implementation of this approach makes it possible to automate the irrigation process and to take into account the indicator that signals water stress of the plant.
Design and study of immunogenicity of virus vaccine against viral pneumoenteritis of calves
Authors: Krasochko P. A. , Ponaskov M. A.
Published: December 2021

The immunogenicity of a virus vaccine against viral pneumoenteritis in young cattle was studied in laboratory animals. The results of the selection of optimal vaccine strains to study the eﬀects of diﬀerent inactivants on infectious rhinotracheitis virus, viral diarrhea, parainﬂuenza-3, respiratory syncytial virus, rotavirus and coronavirus are presented. The accumulation of avirulent vaccine virus strains was carried out using established virological methods on transplanted cell cultures of MDBC (calf kidney cells) and SPEV (fetal pig kidney cells). Theotropine and formalin were used as inactivating agents to develop inactivation regimes for vaccine strains - components of the experimental vaccine. The antigenic activity of attenuated strains of infectious rhinotracheitis virus, viral diarrhea, parainﬂuenza-3, respiratory syncytial virus, rotavirus and coronavirus on white mice and calves and the level of speciﬁc antibodies in the sera of guinea pigs immunized with vaccines using diﬀerent adjuvants were studied. Avirulent strains of viruses were used in the design of a new virus vaccine against viral pneumoenteritis: infectious rhinotracheitis (IBR-VBF-VHAVM No. 404); diarrhea (VDVBF-VHAVM No. 406); parainﬂuenza-3 (PG-VBF-VHAVM No. 403); respiratory syncytial virus (RSV-VBF-VHAVM No. 405); rotavirus (RTV-VBF-VHAVM No. 401) and coronavirus (CV-VBFVHAVM No. 407). The selected vaccine strains are non-reactive and induce active production of antiviral antibodies in suﬃciently high titres in both laboratory animals (white mice) and farm animals (cattle). The most eﬀective inactivating agents are 0.1% theotropine and 0.2% formalin. Two types of oil-based adjuvants, ISA 15 and ISA 25, were used to select the optimal adjuvants for the design of the virus vaccine. Adjuvant ISA 15 was used at 15% of the antigen quantity, ISA 25 at 25%. The adjuvant IZA 15 at a concentration of 15% is the optimum adjuvant for the preparation of an experimental virus vaccine against viral pneumoenteritis in young cattle.
Humanizar a educação em química?
Authors: Oliveira Roberto Dalmo Varallo Lima de , Fary Bruna Adriane , Polizel Alexandre Luiz
Published: December 2021

Este manuscrito busca responder ao questionamento: quais significados de humanidade emergem a partir das reflexões de licenciandos de Química? Para tal, a partir das interações que surgiram em uma aula da disciplina de Filosofia da Ciência para Química, realizamos uma pesquisa que envolveu a confecção de cartas. À luz da análise do discurso, de inspiração em Michel Foucault, estabelecemos quatro eixos de análises para as cartas: 1) “o humano como produção das Ciências”, 2) “a humanização como processo de sensibilização”, 3) “A humanidade como algo deste mundo”; 4) “O humano como ser distinto por composição”. Por meio de um quadro teórico que envolveu Isabelle Stengers, Michel Foucault, Bruno Latour, Ailton Krenak, Eduardo Viveiros de Castro, Adela Cortina, entre outros, discutimos esses eixos. As reflexões nos proporcionaram pensar, também, sobre qual é o papel da Educação em Química - principalmente no que tange à formação de educadores(as) - na construção desses significados.

Published: December 2021

Este artigo apresenta um recorte de uma tese de doutoramento que pesquisou sobre os modos de organização de cursos de formação de professores de Química no Estado de Minas Gerais, tomando como base dimensões formativas necessárias ao desenvolvimento profissional e ao trabalho docente. No presente texto, enfocamos a ‘dimensão conceitual básica e disciplinar’ e a ’dimensão instrumental, técnica e prática’ a fim de delinear o perfil dos cursos de Licenciatura em Química estudados e fazer inferências sobre as possibilidades e necessidades formativas que abarcam a construção da identidade profissional docente. Para tanto, analisamos os projetos pedagógicos do curso de Licenciatura em Química de três universidades públicas federais do referido Estado, no que tange a organização de suas propostas pedagógicas e de suas matrizes curriculares. Identificamos que um dos cursos apresenta a tendência de ofertar uma formação de professores com características bacharelizantes, reverberando em restrições à construção da identidade docente. Já os outros dois cursos, apesar da necessidade de alguns ajustes em suas propostas pedagógicas, propiciam a constituição da identidade profissional dos professores de Química.

O lugar do rei no comércio de escravos: Portugal, Daomé e Porto Novo em 1810
Authors: De Carvalho Soares Mariza
Published: December 2021

Desde os primeiros tempos da expansão portuguesa no Atlântico, ainda no século XV, Portugal mantinha relações diplomáticas com diferentes “reinos” africanos. Em 1810 dois reinos da Costa da Mina enviaram embaixadas à corte portuguesa, então instalada no Rio de Janeiro, para negociar com dom João, então regente de Portugal, novos acordos para o comércio de escravos. Uma embaixada foi enviada por dadá Adandozan que foi “rei” do Daomé entre 1797 e 1818/20; e a outra por dè Ajohan, “rei” de Ardra entre ca.1807 e ca.1816. Ao longo do texto uso os termos “rei” e “reino” para as formações políticas africanas, assim como “embaixadas” e “embaixadores”, porque serem termos que aparecem na documentação portuguesa da época. Essa terminologia indica o reconhecimento desses governantes como autoridade legítima sobre um determinado povo e como interlocutores de relações diplomáticas e comerciais com Portugal.

Isto foi possível através dos avulsos do Arquivo Histórico Ultramarino, da obra do cronista Elias Alexandre da Silva Corrêa e de bibliografia complementar.

Las exportaciones de materias primas en los países latinoamericanos constituyen una fuente fundamental de ingresos para atender sus presupuestos. El banano y plátano son parte de los productos que el Ecuador más exporta a nivel mundial, razón por la cual, la variación de los ingresos por este rubro afecta de manera directa al ingreso de divisas en la economía nacional. El objetivo de la presente investigación consiste en la determinación de los factores que inciden en esta variación, a través del análisis y la descomposición econométrica de la serie temporal de exportación de banano y plátano ecuatoriano en el período 2013 -2017. Como resultado de la descomposición se ha obtenido e identificado los picos negativos y positivos del componente irregular y estos, a su vez, han sido categorizados de acuerdo a un análisis de entorno empresarial, con lo que, finalmente, se ha logrado definir los factores claves que influyen en la variación de los ingresos FOB por exportación de banano y plátano ecuatoriano. Los resultados obtenidos son relevantes, ya que se convierten en un insumo para que las instituciones responsables de la generación de políticas públicas protejan y mejoren la competitividad de estos productos en los mercados internacionales.

La brecha social como factor que incide en la educación a distancia ante la nueva normalidad en México
Authors: Cavazos Guajardo Solís Marcela
Published: December 2021

En el mes de marzo del año 2020, la Organización Mundial de la Salud otorgó el nivel de pandemia al COVID-19,  dados  los niveles de propagación y gravedad; y en México la Secretaría de Salud anunció la implementación de la Jornada Nacional de Sana Distancia, como medida preventiva. De esta manera, se suspendieron las actividades no esenciales y las actividades educativas presenciales en todos los planteles de educación básica, media superior y superior a nivel nacional y, se inició con una nueva modalidad de educación a distancia. La educación a distancia ha representado una gran dificultad en la nueva normalidad, acentuando la brecha social existente y generando una crisis educativa generalizada. 
En el presente artículo se muestra la manera en la que incide la brecha social presente en México, en la nueva normalidad educativa con el modelo a distancia.  Finalmente se concluye que este paso forzado a implementar las clases en línea, puede representar una gran oportunidad para que se cuente con un modelo educativo innovador y equitativo en el país, que permita hacer frente a cualquier eventualidad que pueda presentarse.

The literacy movement by arousing the spirit of ta'awun in ecology is a community service that aims to build a good understanding of ecology, ecological culture, and ecological awareness in Gampingan village. The community service method is carried out by conducting ecological literacy training, counseling, mentoring, and facilitation. Several activities were carried out together (all partners), starting from strengthening the understanding of ecological literacy theory through literacy training and book references. Also, counseling is to increase legal awareness and environmental awareness in the community (ecological awareness). Increasing the understanding of ecological literacy is also carried out by building the "Padepokan Literasi Iqro" as a place to read, write, discuss, and a space to solve ecological problems in Kampung Gampingan.
As controvérsias de Morrissey e a cultura do cancelamento
Authors: Alberto Thiago Pereira , Pereira de Sá Simone
Published: December 2021

O artigo aborda um fenômeno da cultura pop que ganhou visibilidade no contexto das redes sociotécnicas: a prática de “cancelamento” de artistas por fãs. Partindo da premissa de que essa prática se estabelece como uma arma de destaque nas guerras culturais contemporâneas, abordamos o caso do cancelamento do cantor e compositor Morrisey, da banda The Smiths, por parte de seu fandom, na ocasião em que ele se apresentou na televisão americana usando um broche do partido de extrema direita For Britain, buscando contribuir com uma metodologia de análise do fenômeno. Na primeira parte do artigo desenvolvemos o argumento de que a reação ao cantor se dá no horizonte de expectativas (Koselleck,2006) construído a partir da experiência que os fãs tiveram com seu ídolo ao longo da carreira, na qual se destaca a  “performance nostálgica” de Morrisey (Alberto 2021).  A seguir, na segunda parte, utilizamos a noção de coerência expressiva (Pereira de Sá; Polivanov, 2012; Goffman,2009), como chave de análise a fim de rastrear as partes constitutivas desse processo e seguir algumas das suas implicações e tensões.

"Não sou eu quem está falando"
Authors: Cesar Monastier Kleina Nilton , Cardoso Sampaio Rafael
Published: December 2021

Resumo: O artigo realiza uma análise do uso da estratégia argumentativa de autoridade em vlogs publicados no YouTube por produtores de conteúdo conservadores do Brasil. A partir do contexto pré-vacinação contra a COVID-19 no país, entre os meses de outubro de 2020 e janeiro de 2021, identificou-se a partir dos preceitos da Retórica a utilização tanto de argumentos de autoridade para reforçar um posicionamento quanto os de desvalorização de opositor — os ad hominen — em 26 vídeos de 13 canais diferentes. Para obtenção de dados sistematizados, foi realizada uma Análise de Conteúdo. Os resultados indicam que a chamada Nova Direita traz algumas características em comum, como a necessidade de identificar e desqualificar um adversário e a alta valorização da autoridade autoatribuída, ou seja, conferida ao próprio youtuber. Por outro lado, o corpus revela-se difuso no formato de colocação de ideias e na organização de seus argumentos, inclusive com discursos contrários às ações do Governo Federal.
