01 Sep 2015TL;DR: The emotional experiences and the expectations that the pregnant woman has in relation to childbirth in the third trimester are analyzed.
Abstract: Transformations in the way of how pregnancy is experienced in the family, along with the facility of access to information on this subject, have challenged the perception of childbirth as being merely a medical act. This implies alterations on the representations of pregnancy. Consequently, we intend to analyze the emotional experiences and the expectations that the pregnant woman has in relation to childbirth in the third trimester. It consists of a qualitative, descriptive and exploratory research based on a sample of 30 pregnant Portuguese women whose average age is 32 years old. A socio-demographic

Objetivou-se com o presente trabalho determinar a evapotranspiracao (ETc) e o coeficiente de cultivo (Kc) da cultura de feijao-caupi ( Vigna unguiculata L.) cv. Novaera, em condicoes de solo com e sem o uso de cobertura morta. O experimento foi conduzido no campus Cauame da Universidade Federal de Roraima, em Boa Vista, RR, entre os meses de abril a julho de 2014. A evapotranspiracao de cultivo (ETc) foi obtida por meio de lisimetro de drenagem. Os resultados evidenciaram que a ETc do feijao-caupi para ciclo da cultura sem e com cobertura morta foram de 311,0 e 260,4 mm, com valores medios de 3,5 e 3,0 mm dia -1 , respetivamente. O estadio fenologico de maior demanda hidrica foi o reprodutivo atingindo valores de 5,4 mm dia -1 em solo sem cobertura e 4,9 mm dia -1 em solo com cobertura. Os Kc's pelos estadios de desenvolvimento, inicial (I), crescimento (II), reprodutivo (III), e final (IV) pelo metodo de Penman-Monteith foram equivalentes a 0,42; 0,82; 1,60 e 0,79 em solo sem cobertura morta, e 0,30; 0,73; 1,46 e 0,56 em solo com cobertura morta. Semelhante, o metodo de Jensen-Haise apresentou valores de 0,38; 0,76; 1,31 e 0,61 em solo sem cobertura morta e 0,29; 0,67; 1,19 e 0,42 em solo com cobertura morta.

EVAPOTRANSPIRATION (ETc) AND CROP COEFFICIENT (Kc) OF COWPEA CROP IN SOIL WITH AND WITHOUT MULCH COVER IN THE RORAIMA SAVANNAH 2 ABSTRACT The determination of water parameters of a crop during its development is essential to maintain yield without wasting water. This study aimed to determine evapotranspiration (ETc) and crop coefficient (Kc) of cowpea crop (Vigna unguiculata L.) cv. Novaera during the various stages of development in soil conditions with and without mulch. The experiment was conducted in Cauame, campus of the Federal University of Roraima, from April to July 2014, Boa Vista, Roraima state. Evapotranspiration cultivation (ETc) was obtained by drainage lysimeter, while the evapotranspiration reference (ETo) was estimated by Penman-Monteith and Jensen-Haise methods. The results determined that water consumption of cowpea in soil conditions with and without mulch were 311.0 and 260.4 mm, respectively. For Kc's developmental stages, initial (I), growth (II), reproductive (III), and final (IV), Penman-Monteith method showed values of 0.42, 0.82, 1.60, and 0.79 in soil without mulch, and 0.30, 0.73, 1.46, and 0.56 in soil with mulch, although the Jensen-Haise method showed values of 0.38, 0.76, 1.31 and 0.61 in soil with mulch and 0.29, 0.67, 1.19, and 0.42 in soil with mulch. Keywords: Vigna unguiculata. Optimization of water use. Water consumption

14 May 2020TL;DR: In this paper, a novo coronavirus, SARS-COV-2, responsavel pela pandemia da COVID-19, trouxe consigo uma serie de respostas estatais de isolamento social a fim de conter a contaminacao, o que repercutiu em a serie of impactos transversais.
Abstract: O novo coronavirus, SARS-COV-2, responsavel pela pandemia da COVID-19, trouxe consigo uma serie de respostas estatais de isolamento social a fim de conter a contaminacao, o que repercutiu em uma serie de impactos transversais. Fundamentado em um estudo exploratorio e descritivo e em um metodo historico-dedutivo, o objetivo do presente artigo e explorar os impactos da COVID-19 no campo da Educacao lato sensu. Com base nos resultados apresentados, conclui-se que os efeitos sao assimetricos no espaco e no tempo, reproduzindo de modo ampliado assimetrias economicas e educacionais pre-existentes.
