Published: April 2020

A metasurface is a layer of subwavelength-scale nanostructures that can be used to design functional devices in ultrathin form. Various metasurface-based optical devices – coined as flat optics devices – have been realized with distinction performances in research laboratories using electron beam lithography. To make such devices mass producible at low cost, metasurfaces over a large area have also been defined with lithography steppers and scanners, which are commonly used in semiconductor foundries. This work reviews the metasurface process platforms and functional devices fabricated using complementary metal-oxide-semiconductor-compatible mass manufacturing technologies. Taking both fine critical dimension and mass production into account, the platforms developed at the Institute of Microelectronics (IME), A*STAR using advanced 12-inch immersion lithography have been presented with details, including process flow and demonstrated optical functionalities. These developed platforms aim to drive the flat optics from lab to fab.

Authors: Gonzalez Adam M. , Church David D. , Townsend Jeremy R. , Bagheri Reza
Published: April 2020

Several dietary supplements have been proposed as a means of improving muscle strength and hypertrophy when combined with resistance training. However, few have received sufficient attention from sports scientists to produce robust evidence for being well recommended. A growing body of literature has emerged for several dietary ingredients with the potential to promote muscular adaptations. Therefore, the aim of this review is to provide an evidence-based review of the efficacy of emerging nutritional supplements to allow athletes, coaches, and practitioners to make an informed decision when considering their use as a means of improving muscle strength and hypertrophy.

Authors: Herlinah Herlinah
Published: April 2020

The purpose of this study is to describe the characteristics of Bedayan Retna Dumilah dance motions created by S. Ngaliman Condropangrawit. This research uses descriptive qualitative method. The research subjects are three figures who are familiar with the Bedayan Retna Dumilah dance. Data collection techniques used the method of observation, in-depth interviews, and documentation study. Data analysis techniques were conducted through the stages of data reduction, data description, and conclusion drawing. Data validation was conducted through the triangulation of sources. The results show that the Bedayan Retna Dumilah dance is a Surakarta style traditional dance that combines the feeling of classical dance motions of the Surakarta Kasunanan Palace with the sense of motion of Kemlayan village artists. The main idea of the Bedayan Retna Dumilah dance was inspired by Bedaya Bedhah Madiun. The Bedayan Retna Dumilah dance range of motions was taken from the Srimpi Sangupati, the Srimpi Gondokusuma, and the Srimpi Anglirmendung dances range of motions. The characteristics of the range of motions found in the Bedayan Retna Dumilah dance are: 1) Sekaran Lara Retna Dumilah which is a development of the sekaran laras sawit; 2) the standing style sekaran lenggut which is a development of the lenggut on sembahan trapsila and sembahan jengkeng. The two characteristics of the range of motion are not found in the other dances.

Multiple endocrine neoplasia type 1 (MEN1), an autosomal dominant disorder caused by MEN1 germline mutations, is characterised by parathyroid, pancreatic and pituitary tumours. MEN1 mutations also cause familial isolated primary hyperparathyroidism (FIHP), a milder condition causing hyperparathyroidism only. Identical mutations can cause either MEN1 or FIHP in different families, thereby implicating a role for genetic modifiers in altering phenotypic expression of tumours. We therefore investigated the effects of genetic background and potential for genetic modifiers on tumour development in adult Men1+/- mice, which develop tumours of the parathyroids, pancreatic islets, anterior pituitary, adrenal cortex and gonads, that had been backcrossed to generate C57BL/6 and 129S6/SvEv congenic strains. A total of 275 Men1+/- mice, aged 5–26 months were macroscopically studied, and this revealed that genetic background significantly influenced the development of pituitary, adrenal and ovarian tumours, which occurred in mice over 12 months of age and more frequently in C57BL/6 females, 129S6/SvEv males and 129S6/SvEv females, respectively. Moreover, pituitary and adrenal tumours developed earlier, in C57BL/6 males and 129S6/SvEv females, respectively, and pancreatic and testicular tumours developed earlier in 129S6/SvEv males. Furthermore, glucagon-positive staining pancreatic tumours occurred more frequently in 129S6/SvEv Men1+/- mice. Whole genome sequence analysis of 129S6/SvEv and C57BL/6 Men1+/- mice revealed >54,000 different variants in >300 genes. These included, Coq7, Dmpk, Ccne2, Kras, Wnt2b, Il3ra and Tnfrsf10a, and qRT-PCR analysis revealed that Kras was significantly higher in pituitaries of male 129S6/SvEv mice. Thus, our results demonstrate that Kras and other genes could represent possible genetic modifiers of Men1.
El trampantojo francés de la accesibilidad: la vivienda evolutiva
Authors: Boto Álvarez Alejandra
Published: April 2020

La acción pública francesa en materia de vivienda ha sido una constante legislativa en los últimos tiempos, y su último episodio es la llamada Ley ELAN.Lo que aquí se pretende analizar es la génesis, alcance y contenido de la primera parte de su artículo 64, que dispone, con el fin de reducir los costes de construcción, que sólo el 20 % de los inmuebles de viviendas tendrán que ser accesibles para personas con discapacidad. El resto bastará con que sean alojamientos “evolutivos”, que permitan en su caso alcanzar la accesibilidad a través de obras sencillas. La medida parece claramente regresiva y plantea para su aplicación toda una serie de interrogantes de interés que se tratarán de presentar.Se abordará de forma crítica el impacto de este precepto, analizando su tramitación parlamentaria, particularmente agitada, y su posterior validación por el Consejo Constitucional.

Published: April 2020

El Museo de Belas Artes de A Coruña incorpora en sus fondos, por una donación particular en el año 1948, una talla de madera policromada y estofada de inicios del siglo XVIII. En el año 2016, debido al estado de deterioro de la pieza, se inició su proceso de restauración. Este proceso no solo consistió en revertir la pieza a su apariencia estética inicial sino que se complementó con un estudio iconográfico y con una caracterización completa de la madera y del recubrimiento dorado a través de la Tomografía Computerizada (TC) y la Microscopía Electrónica de Barrido (SEM-EDX). La utilización de estas técnicas analíticas ha permitido visualizar el interior y el exterior de la pieza, generar un registro virtual 3D con información estructural, evaluar el estado de conservación de la madera e identificar el tipo de recubrimiento dorado (pan de oro y purpurinas procedentes de antiguas restauraciones). El estudio dendrocronológico, aunque no ha sido concluyente para datar la madera debido al bajo número de anillos presentes en el tronco (representados tan solo 27 años), ha servido sin embargo para evaluar los límites y la potencialidad del uso de la dendrocronología basada en exámenes tomográficos no destructivos en tallas de madera. El proceso de restauración y el estudio iconográfico realizado también se describen en este trabajo. Ambos han ayudado a poner en valor expositivo la pieza y a identificar la identidad del Santo representado que en un origen, fue catalogado como San Gregorio, con dudas sobre su identidad como San Benito y que finalmente es asignado como San Bernardo.
Insulin-Like Signalling Influences the Coordination of Larval Hemocyte Number with Body Size inDrosophila melanogaster
Authors: Bakopoulos Daniel , Beadle Lauren Forbes , Esposito Katherine M , Mirth Christen K , Warr Coral G , Johnson Travis K
Published: April 2020

Blood cells, known as hemocytes in invertebrates, play important and conserved roles in immunity, wound healing and tissue remodelling. The control of hemocyte number is therefore critical to ensure these functions are not compromised, and studies using Drosophila melanogaster are proving useful for understanding how this occurs. Recently, the embryonic patterning gene, torso-like (tsl), was identified as being required both for normal hemocyte development and for providing immunity against certain pathogens. Here, we report that Tsl is required specifically during the larval phase of hematopoiesis, and that tsl mutant larvae likely have reduced hemocyte numbers due to a reduced larval growth rate and compromised insulin signaling. Consistent with this, we find that impairing insulin-mediated growth, either by nutrient deprivation or genetically, results in fewer hemocytes. This is likely the result of impaired insulin-like signaling in the hemocytes themselves, since modulation of Insulin-like Receptor (InR) activity specifically in hemocytes causes concomitant changes to their population size in developing larvae. Taken together, our work reveals the strong relationship that exists between body size and hemocyte number, and suggests that insulin-like signaling contributes to, but is not solely responsible for, keeping these tightly aligned during larval development.
Texto, imagem e visualidade na literatura contemporânea brasileira
Authors: Martoni Alex
Published: April 2020

O aumento significativo, nas últimas décadas, da produção de obras literárias fortemente marcadas pela inclusão de fotografias, pela apropriação e colagem de documentos, e por manipulações gráficas e tipográficas, dentre outras operações realizadas nos níveis textual, paratextual e perigráfico, tem exigido um reexame do modo como nos aproximamos analiticamente das mesmas. Se pensar na relação literatura e imagem significava, predominantemente, refletir sobre a produção de imagens poéticas por meio de tropos linguísticos, os processos crescentes de fixação de imagens e outras formas de visualidade na página impressa exige hoje, do leitor, a consideração da literatura como um objeto  complexo, marcado pelo trânsito de linguagens e por modos técnicos de articulação do sentido. É dentro dessa perspectiva que este artigo buscará mapear as condições de emergência desse fenômeno no âmbito da literatura contemporânea brasileira e propor algumas formas de articulação analítica entre literatura, imagem e visualidade hoje.

THE IMPACT OF ENVIRONMENTAL CHANGES ON BLACK MARLIN, Makaira indica (Cuvier, 1832) ABUNDANCES IN THE EASTERN INDIAN OCEAN
Authors: Setyadji Bram , Fahmi Zulkarnaen
Published: April 2020

Black marlin (Makaira indica) is commonly caught as frozen by-catch from Indonesian tuna longline fleets. Its contribution estimated 18% (~2,500 tons) from total catch in Indian Ocean. Relative abundance indices as calculated based on commercial catches are the input data for several to run stock assessment analyses that provide models to gather information useful information for decision making and fishery management, however, little are known about the influence of environmental factors to its abundance. In this paper, the abundance was represented as standardized index in order to eliminate any bias on other factors which might influence it. Data were collected from August 2005 to December 2017 through scientific observer program (2005-2017) and national observer program (2016-2017). Most of the vessels monitored were based in Benoa Port, Bali. Overall, time trends of abundance was fluctuated, although, there was increasing trend since 2010 then dropped significantly into relatively similar figure in 2005. Even though, Sea Surface Temperature (SST) and Sea Surface Height (SSH) were statistically significant when incorporating into the models, but it allegedly wasn’t the main driver in determining the abundance of black marlin. Instead, it was more likely driven by spatio-temporal factors (year and area) effect rather than environmental changes.
Non-daily current affairs information in prime time: formats and programming strategies in Spanish generalist television (1990-2016)
Authors: Latorre-Lázaro Teresa , Doménech-Fabregat Hugo
Published: April 2020

This paper investigates the evolution of non-daily current affairs formats –other than the news– in the prime time of Spanish generalist television between 1990 and 2016. Analysing the programming content of six channels (TVE, La2, Antena 3, Telecinco, Cuatro and La Sexta), we have studied the presence, typology and strategies of the programmers to incorporate them into the offer of prime time. The longitudinal sample allows us to detect the tendencies that have influenced the audiovisual treatment of the non-daily current affairs information in the most competitive television time slot. The result of the analysis shows that the most important topics on current affairs such as politics, or the economy, have been integrated into the prime time. In addition, there has been a recovery of analytical genres such as the television reportage to explain topics of current interest. This new informative offer, much more innovative in the treatment, has enabled new programming strategies to be applied to the non-daily current affairs formats in order to improve their profitability.
Tradición y transmisión de la fe. El caso de la «religiosidad popular» en el Chile actual
Authors: Aguirre-Romero Federico
Published: April 2020

Desde la segunda mitad del siglo XX, la «religiosidad popular» aparece como un factor determinante en los procesos socioculturales de Latinoamérica. Así, este tópico ha sido ampliamente tratado en el magisterio y las teologías latinoamericanas a partir de los años 60, reconociéndose su progresiva valoración como medio de transmisión de la fe. En lo que sigue, partiendo de una crítica de los términos «religiosidad» y «piedad popular», se propone una perspectiva de análisis teológico-fundamental de este fenómeno, destacando su rol crucial en los procesos de transmisión de la fe y los lenguajes propios a través de los que se expresa.
Jacques Maritain and the Political Theology of Contemporary Democracy
Authors: Molina-Cano Jerónimo
Published: April 2020

This article analyzes the democratic thought of the philosopher Jacques Maritain. A methodical reading of the integrity of his political work published since the 20s demonstrates a great continuity in the defense of a univocal concept of democratic governance, called social democracy, new Christianity, integral democracy or organic democracy in order to accommodate his thought to the political circumstances. Starting from the principle of superiority of spiritual power, Maritain has redefined the notion of democracy in an anti-rousseaunian sense. Maritain postulates a community and pluralist regime under a presidential government and non partitocratic political system. Maritainian democracy and the secular faith that must animate it, based on human rights, is conceived as an antidote against liberal neutralism and against the totalitarian temptation of a democracy understood as a political religion.

Authors: Skliar V. , Krusir G. , Zakharchuk V.
Published: April 2020

Ukraine has a developed agricultural sector, in particular crop production, which is a source of large quantities of production residues and waste. One of the most promising areas for solving environmental problems in the production of grain products is the processing of industrial waste by enzymes and the use of processing products in other industries. The current needs of sustainable environmental practices have increased the use of enzymatic technologies in production processes. Lipases be used in the processing of waste from oil and fat enterprises, namely, waste from the stage of demetallization of hydrogenated fat from vegetable oils by enzymatic hydrolysis.The work is devoted to the study of conditions of enzyme Rhizopus japonicus lipase immobilization and its physical and chemical characteristics. Factors for obtaining immobilized biocatalysts, methods and conditions for determining the activity and stability of immobilized enzymes are highlighted. Lipolytic activity of the enzyme immobilized under these conditions remains more than 30% compared to native, which is a high indicator of activity retention. It has been shown that immobilization promotes the expansion of the pH- and thermo-optimum of the lipase. It was determined that for the Rhizopus japonicus immobilized lipase, the pH optimum increased with a shift from 7.0 to 6.5, and there was an increase in pH stability during prolonged incubation of the immobilized enzyme for alkaline and acidic pH values. It has been established that lipase immobilization leads to expansion of the thermo-optimum, as well as stabilization of the enzyme during prolonged incubation at 40 ° C and at higher temperatures (+60-80 ° C), which are possible when drying the final product. The high activity and stability of the immobilized lipase make it possible to recommend it for biotechnological processing ofoil-fat waste.

Published: April 2020

The article presents the results of studies of hygroscopic properties of chia seeds, which is a relatively new culturefor the Ukrainian industry. Chia seeds are a product with a high nutrient content and rich in trace elements, vitamins andminerals that can be of great benefit to human health. Therefore, the main task of post-harvest technology is to bring it to a state that will ensure long-term storage of chia seeds without loss in weight and poor quality. An important influence on the condition of the grain mass during storage and, in particular, during the initial treatment has its hygroscopicity, ie the ability to sorption and desorption of water vapor. Knowledge about the hygroscopic properties of grain are of practical importance for the scientific substantiation of the choice of rational modes of active ventilation, drying. The main characteristic of hygroscopic properties of grain materials is equilibrium moisture, so its determination is an important step for maintaining the quality of grain. The equilibrium moisture of chia seeds has been determined for the first time. The studies were carried out by the generally accepted tensimetric method in the range of air temperatures in the range of 5... 25 °C and iota relative humidity of 33...70 %, which model the conditions of storage of seeds and corresponding to the long-term average data, correspond to the warm and cold seasons in Odessa region. The influence of relative humidity, air temperature and grain moisture on the equilibrium moisture of chia was investigated, numerical values of equilibrium moisture of chia seeds were determined according to environmental parameters: temperature 5, 15, 25 °C and relative humidity 33, 45 and 70 %.The nature of the change in the equilibrium moisture of chia seeds was determined depending on the temperature and relative humidity. With increasing relative humidity and decreasing ambient temperature, the equilibrium moisture of chia seeds increases. The empirical coefficients and the equation that describes the dependence of the equilibrium moisture of chia seeds on the parameters of ambient air - temperature and relative humidity at which its change can be predicted.The data obtained can be used to select drying and active ventilation modes, as well as storage conditions for chia.

Authors: Makarynska A. , Turpurova T.
Published: April 2020

The article is devoted to the issues of solid biofuel production. The classification of biomass used in the production of solid biofuels by origin is given. The main types of grain waste in the southern region for the production of solid biofuels are identified.The article analyzes the soybean market in the world and Ukraine, shows the trend of growing soybean production, which is caused by the growing demand for food and feed purposes. Soybean yield indicators in Ukraine are analyzed and it is found that Kherson region is one of the leaders of soybean yields for 2019. It is shown that in soybean cultivation in Ukraine a considerable amount of secondary resource is obtained - straw, as a by-product of crop production. It is established that the average yield of rice of Kherson region prevails in Ukraine, a large amount of rice husk is formed during processing of raw rice. Physico-mechanical properties of rice husk and soybean straw have been determined. The possibility of production of fuel briquettes from the waste was considered, technological scheme of production of fuel briquettes from waste, which are formed at the enterprises of processing industry and by-products of crop production is given. The technology of production of fuel briquettes from soy straw and rice husk was introduced at the enterprise of Kherson region, which is engaged in cultivation and processing of soybeans and rice. Quality indicators of fuel briquettes were determined: humidity, ash, sulfur, carbon content, volatile matter yield and specific combustion heat. It is established that the quality of fuel pellets is significantly influenced by humidity, degree of grinding and physical and chemical properties of raw materials. When the moisture content of raw materials more than 14% decreases the density of the granules and, due to the evaporation of moisture, cracks appear in the granules, which reduce their strength. With the reduction of the average particle size of the biomass to 2 mm, the quality of the fuel products increases, but the fine fraction of the biomass of the matrix is erased. The heat of combustion of the obtained solid briquettes exceeds the normative values of European standards at a level not lower than 18 MJ / kg. Ash content (0.5 %), normalized by European standards, is practically unavailable for Ukrainian producers, fuel briquettes made from soy straw and husks have higher normalized ash values in accordance with 7.0 and 14.0 %, which reduces their quality indicators.

Published: April 2020

Abstract Objective: To evaluate the accuracy of chest computed tomography (CT) in patients with suspected severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) infection at a cancer center. Materials and Methods: This retrospective single-center study selected 91 patients who had chest CT and real-time polymerase chain reaction (RT-PCR) test collected at the same day. CT results were classified in negative, typical, indeterminate or atypical findings. Diagnostic accuracy, sensitivity and specificity were calculated for two different scenarios: in the first, only typical findings on CT were considered positive; in the second, both typical and indeterminate findings were considered positive. Results: Mean patients’ age was 58.2 years, most were male (60.4%) and had prior diagnosis of cancer (85.7%). CT showed typical findings in 28.6%, indeterminate findings in 24.2% and atypical findings in 26.4%. RT-PCR results were positive for SARS-CoV-2 in 27.5%. The sensitivity, specificity and accuracy in the first and second scenarios were respectively 64.0%, 84.8% and 79.1%, and 92.0%, 62.1% and 70.3%. Conclusion: CT has a high accuracy for the diagnosis of SARS-CoV-2 infection. Different interpretation criteria can provide either high sensitivity or high specificity. CT should be integrated as a triage test in resource-constrained environments during the pandemic to assist in the optimization of PCR-tests, isolation beds and intensive care units.

Published: April 2020

Resumo A temperatura do ar influencia o desenvolvimento vegetativo e a duração da fase de muda de espécies florestais, uma vez que regula as reações fotoquímicas e bioquímicas da fotossíntese, e por isso é considerada a principal variável meteorológica. O objetivo deste trabalho foi estimar as temperaturas cardinais (basal inferior, ótima e basal superior), que determinam os limiares em que ocorrem desenvolvimento vegetativo, e estimar o filocrono de duas espécies florestais na fase de muda. Para isso, foi instalado um experimento a campo, sob delineamento inteiramente casualizado, em esquema fatorial (2 x 12), sendo duas espécies florestais nativas (pau-ferro - Caesalpinia ferrea Mart. ex. Tul. Var. leiostachya Benth e angico-vermelho - Anadenanthera macrocarpa (Benth) Brenan) e doze épocas de semeadura, com cinco repetições por tratamento. Os valores das temperaturas cardinais para o pau pau-ferro foram: 12,8 °C, 20,7 °C e 46,3 °C e para o angico-vermelho foram: 10,3 °C, 23 °C e 45,5 °C. Já o filocrono médio estimado para o pau-ferro foi de 56,9 °C dia folha-1 e de 163,8 °C dia folha-1 para o angico-vermelho, mostrando que o angico-vermelho necessita de mais energia para promover o desenvolvimento vegetativo quando comparado ao pau-ferro.

Abstract Data from field experiments conducted in vineyards table grape variety of Festival in Petrolina-PE, from October/2009 to November/2010, were used to evaluate the influence of the plastic cover on productivity and economic profitability of the viticulture in the São Francisco River Valley. Three treatments were studied: uncovered canopy (UC), plastic cover placed at 50 cm above the canopy (PC50), and a plastic cover placed at 100 cm above the canopy (PC100). The results indicated that the increased supply of radiative fluxes at the height of the berries in the treatment PC100 contributed to higher productivity, while treatment PC50 had the lowest offer of irradiative fluxes at the height of berries and much lower productivity. The yield obtained in the treatment PC100 exceeded 11 t ha-1 and 12.3 t ha-1 to those of treatments at UC and PC50, respectively. Treatment PC100 also had the lowest amounts of defects of berries, which contributed to higher total revenue. By contrast, treatment PC50 had markedly lower productivity, which represented considerable economic losses.

Published: April 2020

Resumo No presente trabalho, a comparação de três dos principais métodos de estimativa da radiação solar foi realizada: modelos empíricos, Redes Neurais Artificiais (RNA) e Máquina de Vetores de Suporte (SVM). Quatro modelos empíricos considerados clássicos foram calibrados e validados para a estimativa da radiação solar UV horária em Botucatu, Estado de São Paulo, Brasil. Mantendo os modelos empíricos como referências em relação a precisão e variáveis de entrada utilizadas, os desempenhos da RNA e da SVM foram avaliados. Por meio dos parâmetros estatísticos Erro Médio Padrão (MBE) e Erro Médio Absoluto (MAE) foi confirmada a superioridade da SVM em relação à RNA e aos modelos empíricos. Comparada à RNA, a SVM foi capaz de gerar melhores resultados utilizando um número menor de variáveis de entrada. Dentre todos os métodos de estimativa testados, a SVM utilizando o conjunto de variáveis de entrada {UV0, KT} é considerada a melhor alternativa devido ao pequeno número de variáveis de entrada utilizadas e pela relativa acurácia.

Published: April 2020

Resumo O feijão-caupi é uma leguminosa bastante cultivada no Norte e Nordeste do Brasil, mas no Pará, a cultura apresenta baixa produtividade, devido à baixa fertilidade dos solos e especialmente à deficiência hídrica. O trabalho teve como objetivo avaliar o efeito de distintos níveis de deficiência hídrica acumulada durante a fase reprodutiva nas trocas gasosas do feijão-caupi. O experimento foi conduzido em Castanhal-Pa, em 2015 e 2016, em um delineamento de blocos ao acaso, com seis repetições e quatro tratamentos correspondentes à reposição de 100% da água perdida pela evapotranspiração da cultura (T1), a 50% de reposição (T2), a 25% de reposição (T3) e sem irrigação (T4). As trocas gasosas foram medidas no estádio fenológico R9, correspondente aos 64 dias após a semeadura (28 dias após o inicio dos tratamentos). A deficiência hídrica foi calculada pelo balanço hídrico diário considerando a capacidade de água disponível (CAD) e a profundidade efetiva do sistema radicular observada em campo. Não houve diferença significativa entre os anos experimentais além do próprio efeito dos tratamentos. O feijão-caupi mostrou-se sensível ao aumento da deficiência hídrica acumulada, diminuindo sua condutância estomática e taxa de fotossíntese, as quais diferiram significativamente entre os 4 tratamentos. Para o potencial hídrico foliar e carbono interno houve diferença significativa apenas entre os tratamentos extremos. Tal comportamento sugere que o feijão-caupi consegue preservar o potencial hídrico foliar mesmo em condições cumulativas de deficiência hídrica agindo como uma espécie conservadora ao priorizar a manutenção de seu status hídrico ao invés da sua atividade fotossintética. As menores produtividades ocorreram em função do déficit hídrico imposto pelos tratamentos com menores lâminas de irrigação.

ABSTRACT: The objective of this study was to evaluate the effect of digestible methionine and cystine (Met + Cys) levels on the hematological and serum biochemical parameters of broiler chickens during the initial and growth stages. For this, 1,800 male chicks of the Coob 500 strain were used, with 900 chicks in the initial phase (1 to 21 days old) and 900 chicks in the growth phase (22 to 42 days old), distributed in a completely randomized design of five treatments with six replicates of 30 birds. The treatments consisted of 0.545, 0.616, 0.711, 0.782, and 0.853%; and 0.514, 0.571, 0.647, 0.704, and 0.761% digestible Met + Cys for “1 to 21” and “22 to 42” days of breeding, respectively. Results showed that digestible Met + Cys levels in broiler feed altered some hematological parameters (erythrocyte, hematocrit hemoglobin, total leukocytes, heterophile: lymphocyte) and serum biochemistry (uric acid, PST, total LDL, and TG). The digestible Met + Cys levels in the diet of broilers affected the hematological parameters and serum biochemistry, especially at higher levels. From the inclusion level 0.761 of Met + Cist in the broiler diet, red blood cells, hemoglobin and hematocrit changes begin to appear.

ABSTRACT: This study contributes to the extant literature on the nexus among rice, maize and wheat production with agriculture gross domestic product (AGDP) of Pakistan. We use time series data from 1970 to 2017 and employ the Non-linear Autoregressive Distributed Lag (NARDL) model. Short run and long run shocks between the selected variables and result’s is checked through the co-integration and nonlinear error correction model.Autoregressive distributed lag bound testing approach for co-integration and to find the relationship between variables Granger causality test is applied.Our results confirm co-integration, positive shocks results show that rice, maize and wheat production have significantly influence on AGDP. The asymmetrically positive shocks of three crops have neutral effect on AGDP. While in symmetric results show the unidirectional effect between rice, maize production with AGDP and wheat production do not have ganger causality with AGDP. Finally, results depict that wheat, maize and rice production significantly contributes to agricultural GDP in the case of Pakistan.

ABSTRACT: The sensory quality of wines is affected by the compounds produced by the action of the yeasts used in alcoholic fermentation. This work aimed at assessing the physicochemical, aromatic and sensory properties of the ‘Riesling Italico’ white wines produced by using the Saccharomyces and non-Saccharomyces yeasts. The yeasts S. cerevisiae, S. cerevisiae cerevisiae, S. bayanus, Torulaspora delbrueckii and Metschnikowia pulcherrima were inoculated individually into the must. For 10 days, the alcohol was left to ferment in 7 L carboys in triplicate, at 15º C temperature. The standard physicochemical analyses were done and the quality of the wines was determined. The volatile compounds were identified and quantitative descriptive sensory analyses were performed. All the yeasts produced wines with the characteristic alcohol, volatile acidity and residual sugar content as stipulated by the Brazilian legislation. The T. delbrueckii yeast produced high-content phenylethyl acetate, isoamyl acetate and ethyl decanoate wines, of superior olfactory quality and sensory rating.
(Nec) Plus Ultra: as epopeias antes e após as grandes navegações
Authors: Felipe Cleber Vinicius do Amaral
Published: April 2020

RESUMO Até o século XVIII, os gêneros retóricos e poéticos foram regulados pela noção de imitação, ou seja, os poetas emulavam as autoridades (auctoritas) antigas para produzir seus escritos. Trata-se de um paradigma artístico que precedeu o Romantismo e que se amparou nas convenções e na especificidade de cada gênero discursivo. Embora devamos levar em consideração a longa duração da Instituição Retórica, não podemos negligenciar os aspectos históricos que amparam cada poema, ou seja, não é porque imitavam a tradição que não atualizavam suas matérias. Parece-nos que, a partir do século XVI, as epopeias retomaram a ideia de limite, característica da prudência antiga, superada pelo ímpeto centrífugo das grandes navegações. Pretende-se, neste trabalho, apresentar alguns poemas épicos e, com base na maneira como construíram o éthos/a persona dos heróis, analisar um movimento histórico que propõe a superação do Nec Plus Ultra (não mais além) pelo Plus Ultra (mais além), algo que comparece de forma consistente no universo das epopeias.
“Con la esperanza de que los P.P. han de volver”: los esclavos de los jesuitas expulsos bajo la administración laica de Temporalidades (Buenos Aires, 1767-1775)
Authors: Ciliberto María Valeria
Published: April 2020

RESUMEN Hacia 1767 más de 4.500 esclavos afroamericanos vivían y trabajaban en las propiedades que integraban el vasto patrimonio incautado a la Compañía de Jesús en el Río de la Plata. El frágil equilibrio del sistema esclavista iñiguista fue evidenciado por las investigaciones sobre la gestión de las temporalidades, señalando el fracaso de las Juntas en el mantenimiento/control de la mano de obra forzada. Sin embargo, para el caso de Buenos Aires únicamente se ha estudiado la venta de los esclavos secuestrados en su condición de “bienes muebles”. Nuestro trabajo propone reconstruir las decisiones tomadas por la administración laica porteña en relación al tratamiento de esta población e inferir las respuestas que los propios esclavos elaboraron frente a las mismas en el contexto de incertidumbre post expulsión.
De Mato Grosso a Chiquitos: migraciones furtivas en la frontera luso-española
Authors: Martínez Cecilia
Published: April 2020

RESUMEN En el siglo XVIII, a partir del descubrimiento de oro, cientos de portugueses acompañados de miles de esclavos africanos y afrodescendientes, se asentaron en Mato Grosso. Al otro lado del río Paraguay, en la gobernación de Chiquitos, esto se reflejó en una sigilosa pero incesante afluencia de fugitivos - negros esclavos o libres, de origen africano o criollo, mineros, peones de haciendas, soldados desertores, y también de portugueses y criollos blancos ‒, que encontraban en las tierras ubicadas al otro lado de la frontera una vía de escape a circunstancias variadas. El artículo analiza especialmente la fuga de los esclavos negros, a partir de la evidencia tardo-colonial registrada del lado español de la frontera. Enmarcado en el estudio de la frontera luso-española en la última etapa del período colonial, este trabajo se detiene en la migración furtiva desde los dominios de Portugal a los de España.

Authors: Carreta Jorge
Published: April 2020

RESUMO O artigo analisa o surgimento da dermatologia como especialidade médica, situando-a no contexto das transformações mais amplas trazidas pelos estudos anatômicos, pelas mudanças na classificação das doenças e pelas transformações na cultura visual desde o século XVI. Em um segundo momento, procura estabelecer a relação entre aquelas mudanças, que favoreceram a constituição das especialidades médicas, e a moulage, a modelagem das doenças da pele em cera, atividade de grande importância para a consolidação da dermatologia como especialidade médica.
La historia de la historia de las emociones: mapeo de debates en proceso
Authors: Orellán Sara Hidalgo García de
Published: April 2020

RESUMEN La emoción es una categoría analítica que ha irrumpido con fuerza en las ciencias sociales en general, y en el campo de la historiografía en particular, revelándose como especialmente útil para estudiar procesos de cambio político. Se han producido diferentes debates sobre el papel de las emociones en la historia y especialmente en el ámbito político, y este artículo pretende contribuir a la sistematización de estos debates, haciendo un repaso de cómo se ha entendido que la emoción opera en la acción humana desde la Ilustración, cuando se consagra la dicotomía razón-emoción, hasta 1945, cuando la irrupción del llamado “racionalismo de posguerra” degrada y margina a la emoción en política. A continuación se hace un repaso por los movimientos teóricos que restituyen a la emoción como un elemento de análisis central en las ciencias sociales. Finalmente se muestra cómo esta categoría se integra en los estudios historiográficos, y algunos de los debates que están teniendo lugar sobre la misma, especialmente aquellos referidos al poder y al cambio social y político.
Futebol, gênero e homossociabilidade nas redes sociais: a masculinidade no circuito comunicacional do WhatsApp
Authors: Braga Adriana Andrade , Carauta Alexandre Augusto Freire
Published: April 2020

Resumo O futebol é um elemento fundamental na cultura e identidade nacional brasileiras. Marcado por um viés de identidade masculina, o futebol no Brasil relaciona-se a valores como honra, sexualidade e dignidade. A incorporação dos processos digitais na vida cotidiana tem reconfigurado a comunicação tematizada pelo futebol entre torcedores no âmbito das redes sociais. Elementos identificados em estudos anteriores na sociabilidade entre torcedores, como a jocosidade e a afirmação de masculinidade dominantes, atualizam-se nas plataformas digitais. Partindo de uma abordagem netnográfica, esta pesquisa buscou identificar arranjos identitários e interacionais no circuito comunicacional de um grupo de “peladeiros” no WhatsApp. Os resultados apontam para padrões de reiteração da masculinidade hegemônica, em termos de “homossociabilidade masculina”, “jocosidade de gênero” e “sátira política”.
WHAT HAS THE COVID-19 PANDEMIC TAUGHT US ABOUT ADOPTING PREVENTIVE MEASURES?
Authors: Oliveira Adriana Cristina de , Lucas Thabata Coaglio , Iquiapaza Robert Aldo
Published: April 2020

ABSTRACT Objective: to analyze the COVID-19 pandemic and what we have (re)learned from the world experience of adopting prevention measures recommended by the World Health Organization as well as the epidemiological overview in the world, in Latin America and in Brazil. Results: the World Health Organization has pointed out that the path to reduce the speed of circulation of the virus, control and decrease in the number of cases and deaths resulting from this pandemic can only be accomplished with mass adoption of fundamental measures that include hand hygiene, alcohol gel use, cough etiquette, cleaning surfaces, avoiding agglomerations and social distancing. The epidemiological curve of the disease clearly shows the devastating proportions in Italy, Spain and the United States, surpassing China in death records, due to the delay in adopting the aforementioned measures. In Brazil, the rapid progression in relation to the world and Latin America points to an important increase in the number of cases. Conclusion: this is possibly the most serious pandemic in recent human history, and its course can be influenced by the rigor in adopting individual and collective behavioral measures.
