Published: March 2020

Employer branding is an intriguing junction of marketing and human resource management, where the positive intangible perception of the employer makes the organization a valuable. It is antecedents and outcomes have been tried and tested. However, there is a need to empirically test how employer branding lures the employees to perform well and to remain loyal to the employer. This study aimed to find the mediating impact of employee engagement between the relationships of employer branding and performance of the employees and their intention to stay in the companies. By using the structural equation model (SEM), the results revealed the full mediation role of employee engagement in between employer branding and employee performance and their intention to stay. This study implies that the bank needs to induce employees to remain engaged, as, with this, the performance and talent retention will yield.JEL Classification: D23, M31How to Cite:Samo, A.

Published: March 2020

Abstract2020 is a worrying year for all countries, including Indonesia. This is due to the emergence of the Corona virus outbreak, which originated in Wuhan City of China, and spread throughout the world. Initially the government did not follow the method used by several other countries related to information provided about the corona covid-19 virus, namely by conducting a quick reaction of prevention socialization. The reason is so that the Indonesian people are not worried about issues that are worrying, other than to minimize the existence of Hoax news from a handful of irresponsible people. Finally the covid-19 outbreak also became a concern for the community, because many Indonesians were affected by the transmission of this virus. Therefore, the government took the initiative to take a lockdown policy for 14 days to anticipate the transmission of this corona outbreak. The study uses qualitative research methods with a literary and empirical approach. The data obtained comes from several regulations, such as the Governor of DKI Jakarta and several other regulations and policies, as well as phenomena that occur in the field. The results of the study stated that Indonesia had experienced a condition where the community's concern about Covid-19 was quite large, so that a government policy to lockdown was needed, as an effort to break the chain of the spread of the Corona Covid-19 virus.Keywords: Corona Virus, Lock Down, Government Policy AbstrakTahun 2020 merupakan tahun yang mengkhawatirkan seluruh negara, tanpa terkecuali negara Indonesia. Hal itu disebabkan munculkan wabah virus Corona, yang bermula dari Kota Wuhan China, dan menyebar ke seluruh penjuru dunia. Awalnya pemerintah tidak mengikuti cara yang digunakan oleh beberapa negara lainnya terkait informasi yang diberikan mengenai virus corona covid-19, yaitu dengan melakukan reaksi cepat sosialisasi pencegahan. Penyebabnya, agar masyarakat Indonesia  tidak khawatir dengan isu yang mengkhawatirkan, selain untuk meminimalisir adanya berita Hoax dari segelintir orang yang tidak bertanggung jawab. Akhirnya wabah covid-19 ini juga menjadi hal yang mengkhawatirkan bagi masyarakat, karena banyak warga Indonesia yang terkena dampak penularan virus ini. Oleh karenanya, pemerintah berinisiatif untuk mengambil kebijakan lockdown selama 14 hari guna mengantisipasi penularan wabah corona ini. Penelitian menggunakan metode penelitian kualitatif dengan pendekatan literatur dan empiris. Data yang didapat berasal dari beberapa Peraturan, seperti Peraturan Gubernur DKI Jakarta dan beberapa peraturan dan kebijakan lainnya, serta fenomena yang terjadi di lapangan. Hasil penelitian menyatakan bahwa Indonesia sudah mengalami kondisi dimana kekhawatiran masyarakat terhadap covid-19 cukup besar, sehingga diperlukan kebijakan pemerintah untuk melakukan Lockdown, sebagai upaya memutus mata rantai penyebaran virus corona Covid-19Kata kunci : Virus Corona, Lock Down, Kebijakan Pemerintah
On the solvability of a mixed problem for a fractional partial differential equation with delayed time argument and Laplace operators with nonlocal boundary conditions in Sobolev classes
Authors: Babayev Mahkambek M.
Published: March 2020

In this paper, we study a problem with initial functions and boundary conditions for partial differential equations of fractional order with Laplace operators. The boundary conditions of the problem are nonlocal, and the solution is supposed to belong to one of Sobolev classes. The solution of the initial boundary value problem is constructed as the sum of a series of multidimensional spectral problem’s eigenfunctions. The eigenvalues of the spectral problem are found and the corresponding system of eigenfunctions is constructed. It is shown that this system is complete and forms a Riesz basis in the subspaces of Sobolev spaces. Basing on the completeness of the eigenfunctions’ system, the uniqueness theorem for the solution of the problem is proved. The existence of a regular solution of the initial boundary value problem is proved in Sobolev subspaces.

Authors: Gorskaya Victoriya A. , Polotovskiy Grigory M.
Published: March 2020

In the first part of the 16th Hilbert problem the question about the topology of nonsingular projective algebraic curves and surfaces was formulated. The problem on topology of algebraic manifolds with singularities belong to this subject too. The particular case of this problem is the study of curves that are decompozable into the product of curves in a general position. This paper deals with the problem of topological classification of mutual positions of a nonsingular curve of degree three and two nonsingular curves of degree two in the real projective plane. Additiolal conditions for this problem include general position of the curves and its maximality; in particular, the number of common points for each pair of curves-factors reaches its maximum. It is proved that the classification contains no more than six specific types of positions of the species under study. Four position types are built, and the question of realizability of the two remaining ones is open.
Crisis of the Economic and Social Model of the Nordic Countries: The Experience of Denmark, Norway, Finland and Sweden
Authors: Demina Ekaterina A.
Published: March 2020

Introduction. The Nordic countries are the most economically developed and stable ones in terms of the political and social context. However, the processes of globalization, social and demographic change, business development, increased competition and commercial interests modify the functioning of the economic and social model of the Nordic countries, which experienced a number of crisis phenomena at various stages of its development. The objective of this piece of research is to analyze the prospects for the development of the Nordic model of the social state based on the study of its structure and historical development.

Materials and Methods. The economic situation in the Nordic countries is the object of this study. To achieve the goals and objectives set, the research employed concrete structural analysis (to describe the theoretical aspect of the model) as well as concrete historical analysis (to study the processes of formation and development of the model).

Results. The analysis of the Nordic economic and social model has been carried out; the theoretical aspect of the social and economic model as well as the historical context and the process of its development have been studied. The crisis phenomena and methods used to overcome the crisis of the social and economic model have been analyzed. A range of potential challenges have been identified and the prospects for the development of the region have been presented.

Discussion and Conclusion. The model studied is capable of structural changes provoked by external factors and challenges. The economic experience of the Nordic countries is of interest to us not only in terms of the success of this model, but also in terms of overcoming the crisis. The results of the study can be used when developing new models that can be applied in other countries, taking into account their economic characteristics.

Despite treatment advances, the prognosis of patients with both primary and secondary pulmonary hypertension (PH) remains unfavorable. The increased activity of the sympathetic nervous system is one of the universal mechanisms involved in the PH pathogenesis. Pulmonary artery denervation is a novel minimally invasive pathogenetic method of PH treatment. The denervation procedure is mainly implemented by using radiofrequency ablation of the pulmonary trunk, where most sympathetic nerve fibers are located. In this article we present an overview and analysis of the present state, results of various experimental and clinical studies, as well as clinical experience. The results of studies demonstrated the safety of endovascular surgery and its beneficial effect on both hemodynamic and clinical parameters.
Novel score for mortality risk prediction 6 months after acute coronary syndrome
Authors: Erlikh A. D.
Published: March 2020

Aim.To create a prediction score for assessing the mortality risk 6 months after hospitalization with acute coronary syndrome (ACS).

Material and methods.Based on the results of ACS RECORD-3 register (Russia), we determined independent mortality predictors 6 months after ACS by performing multivariate regression analysis in patients discharged alive from the hospital with known outcomes.

Results.The following predictors were obtained during the analysis: non-prescription of aspirin at discharge (odds ratio (OR) 5,8; 95% confidence interval (CI) 2,315,0; p<0,0001), newly diagnosed heart failure, pulmonary edema or shock in a hospital (OR 5,7; 95% CI 2,6-12,7; p<0,0001), age ≥75 years (OR 5,3; 95% CI 2,710,6; p<0,0001), non-prescription of beta-blockers at discharge (OR 5,0; 95% CI 2,3-10,8; p<0,0001), in-hospital management without  immediate percutaneous coronary intervention (PCI) (primary PCI during ST-segment elevation ACS or PCI during the first 72 hours with non-ST-segment elevation ACS) (OR 3,9; 95% CI 1,69,8; p=0,004), the initial serum creatinine ≥100 µmol/L (OR 3,1; 95% CI 1,6-6,1; p=0,001), body mass index <30 kg/m2 (OR 2,8; 1,2-6,3; p=0,014). Each of them was evaluated at one point and was a component of the RECORD-6 score. Prediction sensitivity and specificity for the new score were 73,3% (95% CI 60,1-83,5) and 71,4% (95% CI 68,9-73,7), respectively; prediction accuracy, estimated as the area under the ROC curve was 0,931 (95% CI 0,897-0,964). The cut-off point was considered 3 points, which had the best ratio of prediction sensitivity and specificity. The mortality after 6 months with a value of <3 points was 1,6%, and with a value of ≥3 points — 10,1% (relative risk (RR) 0,16; 95% CI 0,09-0,28; p<0,0001), and the mortality after 12 months was 7,8% and 22,5%, respectively (RR 0,35; 95% CI 0,25-0,49; p<0,0001). Relative to the GRACE risk score for 6-month mortality showed that the prediction value of the RECORD-6 score was at least no worse.

Conclusion.The novel RECORD-6 risk score is an accurate and simple prediction tool for assessing the mortality risk 6 months after discharge from the hospital. The prediction accuracy of the RECORD-6 risk score is not lower the GRACE risk score.

Published: March 2020

Aim. To study the cardiac remodeling in heart failure (HF) patients with atrial fibrillation (AF) and chronic obstructive pulmonary disease (COPD).

Material and methods. The study included 120 patients who were divided into 4 groups: the experimental group — patients with HF, AF and COPD (n=29), group 1 — patients with COPD, without cardiovascular disease (n=28), group 2 — patients with HF and COPD, without AF (n=30), group 3 — patients with HF and AF, without COPD (n=33). All patients underwent echocardiography using the MyLab70 Ultrasound System (Esaote, Italy).

Results. In comparison with patients of group 3, patients of the experimental group had lower left and right atrial volumes (p=0,001 and p=0,004, respectively), higher right ventricular (RV) wall thickness (p<0,001), lower RV end-diastolic area index (p=0,007) and fractional area change (FAC) (p=0б011), which indicates the effect of chronic airway obstruction on cardiac remodeling in patients with combination of these pathologies. In comparison with patients of group 2, patients of the experimental group had significantly larger RV dimension (p=0,012) and higher RV endsystolic area index (p<0,001), as well as lower systolic RV function (ejection fraction (p=0,002), FAC (p<0,001), tricuspid annular plane systolic excursion (p=0,012)) and higher pressure in the pulmonary circulation (p=0,001). This is due to high hemodynamic load on the RV related to AF and chronic airway obstruction.

Conclusion. The results of the study revealed features of cardiac remodeling pathogenesis in HF patients with AF and COPD. Comparative analysis of the results made it possible to indicate different mechanisms underlying AF, to assess the effects of both AF and chronic airway obstruction on the cardiac structure and function in patients with HF and combination of these pathologies.

Published: March 2020

Aim. To assess five-year changes of somatic risk factors and comorbidities in patients with angina of effort.

Material and methods. The study included 320 patients (143 men and 177 women aged 40-69 years) with coronary artery disease (CAD), class I-III angina of effort. Patients underwent examinations in 2012 in three medical centers of the Republic of Ingushetia (Russia), and in 2017 they were invited for a second complex examination with questionnaires, biochemical analysis, and instrumentation.

Results. Over the five-year follow-up, there was an increase of men with class III effort angina up to 45%; a similar trend was observed in women. Both men and women experienced a three-fold increase in the incidence of type 2 diabetes. Initially and during the follow-up, chronic obstructive pulmonary disease was diagnosed 2 times more often in men than in women, which may be associated with smoking. A small increase in the total cholesterol level was recorded in the cohort; among women, these changes were significant. Target levels reach no more than 20% of patients. A significant increase of blood glucose levels over the 5-year period was observed in a cohort of men and women with effort angina.

Conclusion. Over the 5-year follow-up, there was a clinical deterioration of the effort angina, which is associated with an increase in the incidence of some somatic diseases and the severity of the main behavioral and biological risk factors.

Published: March 2020

Aim. To study the prospects of using parameters of right ventricle (RV) longitudinal strain (LS) during systole for the differential diagnosis of RV myocardial infarction (RVMI) and pulmonary embolism (PE).

Material and methods. The study included 83 patients who were hospitalized with RVMI or PE in the period from December 2017 to May 2019. The study of RV LS using the two-dimensional speckle-tracking echocardiography was carried out in 30 patients with RVMI (group 1), 15 patients with high-risk PE (group 2), and 38 patients with intermediate-risk PE (group 3).

Results. The mean values of RV global LS in patients of groups 1 and 2 did not differ (12,8±2,69 and 12,0±2,56%, respectively) and were significantly lower than in patients of group 3 (15,9±3,03%). The ratio of the interventricular septum (IVS) LS to the RV free wall (FW) LS in the group 1 (1,04±0,43) was significantly lower than in the groups 2 (1,61±0,52) and 3 (1,29±0,38). The ratio of the LS of the RVFW basal segment to the apical segment in group 1 (0,60±0,37) was also significantly lower than in groups 2 (1,69±1,57) and 3 (1,67±1,33).

Conclusion. In patients with RVMI, there is a comparable decrease in the LS of the RVFW and IVS, and the LS of the basal segment decreases to a greater extent than the apical one. In patients with PE, the decrease in the LS of the RVFW is more pronounced than in IVS, and the LS of the apical segment decreases to a greater extent than the basal one. These differences can be used for the differential diagnosis of RVMI and PE.

Published: March 2020

Resumo: O Kanban é um arranjo tecnológico de organização do cuidado hospitalar orientado para a gestão de leitos e da clínica, que visa à qualidade e integralidade da assistência, maior rotatividade dos leitos, com consequente redução do tempo de internação e custos hospitalares. O constante e atualizado acompanhamento do paciente, compartilhado pela equipe profissional em reuniões sistemáticas é seu elemento mais marcante e inovador. O objetivo foi caracterizar os prováveis impactos da adoção de tal arranjo no poder profissional (autonomia e autoridade) dos médicos. Estudo qualitativo em hospital de urgência-emergência municipal com uso das seguintes técnicas de produção de dados: etnografia do cotidiano do hospital, com observação e registro em diários de campo, e realização de seminários compartilhados entre pesquisadores e equipes. Os médicos valorizam o trabalho multiprofissional como um qualificador de sua prática, em uma linha auxiliar e complementar. Acresce que o Kanban tende a ser controlado por “híbridos” (médicos que acumulam funções gerenciais e clínicas) que traduzem sinergias entre “gestão clínica” e “gestão de leitos”. Assim, interferências no trabalho dos médicos não são exercidas de fora, e as suas decisões clínicas continuam a condicionar o trabalho dos demais grupos profissionais. Os médicos não percebem sua autoridade e autonomia ameaçadas pelo Kanban, dada a articulação entre a autoridade administrativa e a autoridade profissional. Contudo, aspectos relacionados à hibridização e estratificação interna da profissão médica precisam ser mais convocados para o debate do poder profissional em saúde.

ABSTRACT The objective of this study was to identify the best regions for allocation of a forestry outgrower scheme, and the most efficient transportation system, using a mathematical programming model to minimize the wood supply costs in three Brazilian states. The forest outgrower scheme is a partnership between producers and forest companies, without land acquisition by the companies. Forest producers are recognized as an important source of growth for forest production. In order to achieve successful partnerships, the company needs to plan its hiring. In this study, the partnerships are made through formal contracts and the model does not allow breach of contract. Six scenarios were modeled and evaluated based on the total cost of the objective function, average wood cost (USD/m3), average transport distance (km) and processing time. The mathematical model showed its efficiency, effectiveness, and flexibility in generating scenarios to support company managers in the decision-making and to avoid breach of contract. Hiring planning benefits both sides as it ensures the company’s production and provides financial security to forest producers. In addition, the model suggests alternatives such as the differential pricing of wood according to the location of the regions and the formation of homogeneous blocks of contracting/renewal of outgrower schemes around the pulp mill.

Published: March 2020

Resumo Os investimentos em sistemas de tratamento de resíduos de suínos (STRS) buscam muito mais contemplar questões de segurança, sanidade e de atendimento a requisitos da legislação ambiental do que investigar possibilidades de explorar economicamente os resíduos devidamente tratados. Este estudo analisou o retorno de investimentos de diferentes STRS sendo realizado entre os meses de outubro de 2013 a maio de 2014. Para a coleta de dados, foi elaborado um questionário eletrônico aplicado por meio de entrevistas em 37 granjas do estado de São Paulo escolhidas aleatoriamente. Para análise de viabilidade econômica dos diferentes STRS, utilizou-se a técnica de orçamento de capital (PAYBACK e TIR). As granjas foram divididas em quatro categorias: GEEBC - Geração de energia elétrica, biofertilizante e créditos de carbono; GEEBI - Geração de energia elétrica e biofertilizante; GEEEL - Geração de energia elétrica; SGPVA - Sem geração de produtos de valor agregado. O melhor resultado econômico foi observado na categoria GEEBC com tempo médio de retorno financeiro de nove anos. Observou-se que 73% dos pesquisados não exploravam o valor econômico dos resíduos tratados, mantendo seus investimentos com intuito de contemplar a legislação ambiental vigente.

Published: March 2020

Abstract The effects of supplement doses (0, 1, 2 and 3 kg ha-1 day-1) and grazing periods (1, 28, 59, 89 and 103 days) on the B. decumbens cv. Basilisk structure and cattle production in deferred pastures were evaluated. The design was a randomised complete block design with two replications. The sward height and the total forage and stem masses decreased with grazing period. The crude protein (8.12%) and in vitro organic matter digestibility (52.74%) were not affected by grazing period. The fibre content in neutral and acid detergent increased linearly with the grazing period. The average daily gain of cattle ranged from 0.419 to 1.019 kg animal-1 day-1; the stocking rate ranged from 2.7 to 3.9 animal unit ha-1; and the average gain per area ranged from 2.7 to 7.9 kg ha-1 day-1, with the maximum values obtained with the highest dose of concentrate. Concentrate supplementation increases cattle production in deferred pastures. During the use of deferred pasture in winter there are decreases in the quantity and quality of forage, as well as limitations in its structure.

Resumo Dois experimentos foram realizados para verificar a viabilidade de diluentes para sêmen equino refrigerado. O objetivo do primeiro experimento foi verificar a eficiência do leite UHT integral e semidesnatado, comparado ao leite desnatado. Amostras foram analisadas a fresco e posteriormente diluídas em leite UHT integral, semidesnatado e desnatado. Foram realizados exames de motilidade espermática e vigor, CFDA/PI e HOST pós-diluição (0h), e no sêmen refrigerado a 5 ºC após 24 e 48 horas. Não houve diferença entre os três diluentes, quanto à motilidade espermática (p=0,9880), vigor (p=0,7249), CFDA/PI (p=0,3382) e HOST (p > 0,01). Houve uma diminuição na qualidade do sêmen, no decorrer do tempo (p < 0,01), independente do diluente utilizado. Pode-se afirmar que, na falta de leite UHT desnatado, o semidesnatado e o integral podem ser usados, uma vez que eles não provocam prejuízo na qualidade do sêmen refrigerado armazenado por até 48 horas. No segundo experimento, o objetivo foi verificar a eficácia do leite desnatado em comparação com diluentes comerciais (Botusemen® (BS) e Botusemen Special® (BSS)). Logo após a coleta do sêmen, as amostras foram diluídas com leite UHT desnatado (LD), Botusemen® (BS) e Botusemen Special®(BSS). A análise de sêmen seguiu o mesmo protocolo do primeiro experimento. As amostras de sêmen refrigeradas com BSS apresentaram HOST e CFDA/PI (p< 0,001) maiores nas 24h e 48 h o que indica que o diluente BSS promove aumento da longevidade dos espermatozoides em comparação com os outros analisados.

Resumo Avaliou-se o potencial de reprodutibilidade e repetibilidade de um sistema semiautomático de mensuração radiográfica. Para isto foram mensurados, por intermédio de um software o vertebral heart score (VHS) e a área cardíaca normalizada (ACN) em imagens radiográficas de cães da raça poodle clinicamente normais e portadores de insuficiência valvar mitral. Dada a subjetividade da análise da silhueta cardíaca por diferentes observadores, acredita-se que mesmo com um sistema semiautomático essa avaliação poderia ser afetada pela experiência prévia do observador em radiodiagnóstico. Foram analisadas cinquenta e sete imagens radiográficas torácicas de cães atendidos em um hospital veterinário. As imagens foram analisadas por dois grupos de observadores com diferentes níveis de experiência em radiologia: (A) sem experiência (n = 2) e (B) com experiência (n = 2). Demonstrou-se boa repetibilidade e reprodutibilidade para o VHS independente da experiência em radiodiagnóstico, e para a ACN em observadores experientes e com familiaridade com o software.

Resumo O presente estudo avaliou a presença de Salmonella spp. em 89 amostras de produtos cárneos comercializados na região sul do Rio Grande do Sul e, a partir dos isolados obtidos, foi verificada a capacidade de resistência a agentes antimicrobianos e de formação de biofilme em superfícies de poliestireno. Foi constatada a presença de Salmonella spp. em 19,1% das amostras avaliadas e, dos isolados obtidos, 40% mostraram resistência a pelo menos um dos agentes antimicrobianos testados e 33,3% manifestaram-se multirresistentes. Apenas o antimicrobiano amicacina (30 µg) foi eficaz na inibição de todos os isolados testados. Nenhum isolado mostrou-se capaz de formar biofilmes em superfícies de poliestireno.

Abstract The objective of this research was to measure the ingestive behavior of steers finished exclusively with concentrate containing soybean hulls (ground) and/or white oat grain.We used 32 steers with Charolais or Nellore predominance.The animals were randomly distributed in the treatments, blocked according to genetic predominance, and allocated in individual pens. Diets were isonitrogenous, being the treatments: Soybean hulls; White oat grain or the Mixture (equal parts), plus limestone and protein nucleus. Steers that received the diet based on soybean hulls remained more time in idle compared to the ones that received the mixture, and these remained more time in idle than the steers that received the diet based on white oat grain. Steers that received the diet based on soybean hulls ruminated less time than the steers fed the mixture, and these less time than those fed white oat grain. Exclusively concentrate diets based on soybean hulls although presenting high soluble fiber content in neutral detergent, are not sufficient to promote an appropriate ingestive behavior of steers of Charolais or Nelore racial predominance.
Fruto-oligossacarídeos: aspectos nutricionais, tecnológicos e sensoriais
Authors: Macedo Leandro Levate , Vimercati Wallaf Costa , Araújo Cintia da Silva
Published: March 2020

Resumo Este trabalho objetivou apresentar os fundamentos sobre fruto-oligossacarídeos (FOS), seus métodos de obtenção, estabilidade em alimentos processados e aspectos nutricionais. Os FOS são carboidratos naturais presentes em diversas espécies de plantas, compostos por 2 a 10 monômeros de sacarídeos. Além da obtenção natural, que ocorre através da extração em fontes vegetais, esses carboidratos podem ser obtidos pela hidrólise enzimática da inulina, realizada pelas inulinases, ou ainda sintetizados a partir de resíduos de sacarose. Os FOS são estáveis perante a maioria dos processos realizados nos alimentos, sofrendo maiores degradações em processos térmicos envolvendo alta temperatura e/ou pH extremo. Tal característica favorece a industrialização de produtos ricos em FOS e a adição desses compostos como ingredientes. Esse grupo de carboidratos tem ganhado cada vez mais destaque nos últimos anos perante a capacidade de exercerem diversas funções benéficas ao organismo, pois são considerados como prebióticos e fibras solúveis. A ingestão de FOS está associada à redução do risco de câncer de cólon, diabetes, obesidade, doenças cardiovasculares e ao aumento da absorção de alguns minerais. Além disso, são caracterizados pela boa aceitação sensorial, solubilidade e capacidade de retenção de água. Entretanto, o consumo deve ser moderado, pois, em grandes porções, pode causar alguns desconfortos ao indivíduo, tais como flatulência.

Published: March 2020

Abstract Eggs, often used in pastry products, are one of the major transmission vehicles of Salmonella. The main purpose of this study was to evaluate Salmonella Typhimurium thermal resistance, by D and z values determination, in a traditional Portuguese egg-based pastry and its microbial and physical-chemical characterization. Salmonella Typhimurium ATCC 14028 (OXOID C6000L) (Ca. 1.33×108 cfu g-1) was inoculated in a liquid batter consisting of 8 whole eggs, 7 egg yolks, 280 g of wheat flour and 250 g of sugar. D and z values determinations were performed after applying a water bath to vacuum-packed samples of liquid batter (5 g), following thermal treatments: 52 °C (45, 90, 135, 180 and 225 min); 55 °C (15, 30, 45, 60, 70 and 80 min); 58 °C (5, 10, 15, 20, 25 and 30 min) and 61 °C (1, 2, 3, 4 and 5 min). Physico-chemical (aw, pH, moisture, sugar, ashes, protein and free fat) and microbiological determinations (mesophilic microorganisms, psychrotrophic, molds and yeasts, Enterobacteriacea, E. coli; Salmonella spp., Bacillus cereus, Listeria monocytogenes and Staphylococcus aureus) were also conducted in raw liquid batter. It was possible to investigate different combinations of time and temperature for Salmonella Typhimurium inactivation, compared to other studies on egg-based batter, often used to make pastry products. Liquid batter aw before inoculation was 0.94 and pH 7.26. The D values were obtained 53.19 min, 20.45 min, 6.95 min and 1.60 min, at 52 °C, 55 °C, 58 °C e 61 °C, respectively. From the calculated D values, the corresponding z value was 5.96 °C.
Algoritmos racistas: a hiper-ritualização da solidão da mulher negra em bancos de imagens digitais
Authors: Carrera Fernanda , Carvalho Denise
Published: March 2020

Resumo Reconhecendo a importância das discussões a respeito dos algoritmos em mecanismos de busca e seus vieses possivelmente discriminatórios e racistas, este trabalho analisa três bancos de imagens digitais e seus resultados para as palavras-chave “family”, “black family” e “white family”. Com base no conceito de “hiper-ritualização” de gênero de Erving Goffman (1979), estuda-se aqui se a perspectiva imagética de família (mulher, homem, filho e filha) se aplica para o contexto negro ou, ao contrário, corrobora para a “solidão da mulher negra”. Analisando comparativamente mais de 2.500 imagens, percebeu-se que as mulheres negras são mais representadas sozinhas com seus filhos do que as mulheres brancas; a palavra-chave “family” resulta em maioria expressiva de famílias brancas; e a pesquisa por “white family” apresenta mais resultados “infiltrados” de famílias negras como indício de racialização da pesquisa para o algoritmo de busca, que considera a branquitude como normativa e neutralidade.
Pensar Contra os Dualismos: resenha de filosofia ciborgue
Authors: Sousa Adriano Carvalho Araujo e
Published: March 2020

Resumo Na experiência contemporânea, a multiplicação de próteses, interfaces e máquinas convoca imediatamente a pensar ciborgue como o que problematiza relações entre natureza e artifício. Ciborgue comporta diversidade, pode se constituir a partir de uma intervenção cirúrgica ou como um Organorg. Thierry Hoquet observa exemplos no cotidiano e nas artes, propõe cartografar o lugar ocupado por esse corpo tecnológico no pós-humano e por um novo feminismo pensado a partir dessas categorias.

Authors: FRANCO DANILO , GOES ANTONIO DE , PEREIRA FERNANDA DIAS
Published: March 2020

ABSTRACT Citrus black spot (CBS) is a severe disease for citriculture in the São Paulo State, Brazil. Part of its management is focused on chemical control using cupric fungicides and strobilurins. The objective of the present work was to evaluate the efficacy of three sources and three concentrations of cupric fungicides (copper hydroxide, copper oxychloride and cuprous oxide). Orange fruits of the Pera cultivar were bagged in the plants and the treatment with cupric fungicide was applied. The fruits were inoculated (by spray) with Phyllosticta citricarpa (1×104 conidia mL-1) after 0, 7, 14, 21, and 28 days, and bagged again. The evaluation of incidence and severity was did at the harvest time of fruits. A second experiment was conducted under natural infection with the same treatments, consisting of application of fungicides at the stages F1 (petal fall) and F2 (fruits with diameter of 1 cm), using mechanized sprayer with mean flow of 7.35 L solution plant-1. Subsequently, all treatments received four applications of azoxystrobin (30 g ha-1), plus mineral oil at 0.25%. Four monthly evaluations were done to determine the CBS incidence and severity. The initial applications with cupric fungicides are essential for the control of CBS; the fungicide copper hydroxide showed the best control of CBS with the lowest rate of metallic copper (43.7 g of Cu++ 100 L-1) in both experiments, regardless of the conduction conditions.

ABSTRACT The cover crop straw may cause changes in the microbial activity and population, with repercussions on environmental changes and on the C and N dynamics, providing important information for the planning of adequate land use in the Cerrado. The objective of this study was to evaluate the effect of straw of cover crops on the soil microbial attributes and quality of organic matter. Experimental units consisted of 100 g of sieved soil placed in small plastic cups mixed with straw from cover plants. Treatments were distributed in a CRD, in a factorial scheme of 7 x 7 + 1, with seven types of straw, evaluated at 7, 14, 21, 28, 42, 63 and 105 days after incubation, and control without straw, with three replicates. The qCO2 ranged from 0.1 (Crotalaria spectabilis at 14 days) to 5.1% (Cajanus cajan ‘IAPAR 43’ at 42 days). The organic carbon and nitrogen reservoir are differently affected by straw of legumes and grasses on the dates. The incorporation of Brachiaria brizantha and Mucuna aterrima had a positive impact on the microbial attributes until the 21st incubation (qCO2, Cmic and Nmic), with little loss of carbon dioxide and growth of the microbial population. All the evaluated species presented a potential to be used in crop rotation systems, enabling no-tillage systems in the Cerrado of Piauí. However, it is recommended to select species according to specific purposes. Thus, the use of cover crops is an important tool for increasing the biological quality of Brazilian northeastern cerrado soils.

ABSTRACT During the chemical control of pests, diseases and weeds, great importance is given to the phytosanitary product and little attention to the application technology. The control of soybean pests did not escape the general rule and, therefore, some pests known as secondary, and even nonexistent, became responsible for great damage to the soybean crop. The objective of this work was to test the application of insecticide at different speeds (5 and 16 km h-1) by varying the rates of application in 108 to 110 and 199 to 216 L ha-1 to quantify the difference in the coverage percentage of the applied insecticide in the canopy of soybean plants, and to verify the interaction of these factors with efficacy parameters for the control of caterpillars (Helicoverpa armigera and Chrysodeixis includens). In general, the highest leaf coverage by the insecticide was observed in the upper part of the canopy, regardless of the rate and speed of application, resulting in lower leaf damage. For the middle and lower thirds of the plant, the decrease in speed influenced more the decrease in leaf damage by the caterpillars than the increase in the spray volume.
