    In this work we will prove the existence uniqueness and asymptotic behavior of weak solutions for the system (*) involving the pseudo Laplacian operator and the condition ut+i=1nuxip2uxiνi+uρu=f\displaystyle\frac{\partial u}{\partial t} + \sum_{i=1}^n \big|\frac{\partial u}{\partial x_i}\big|^{p-2}\frac{\partial u}{\partial x_i}\nu_i + |u|^{\rho}u=f on Σ1\Sigma_1, where Σ1\Sigma_1 is part of the lateral boundary of the cylinder Q=Ω×(0,T)Q=\Omega \times (0,T) and ff is a given function defined on Σ1\Sigma_1

    Embriões bovinos produzidos in vitro, em estádio de mórula, foram cultivados em meio contendo anticorpos anti H-Y de alto título proveniente de ratos por 24h e, após este tempo, classificados em dois grupos: 1) embriões inibidos em estádio de mórula (classificados como machos) e 2) embriões que se desenvolveram e formaram a blastocele (classificados como fêmeas). O sexo de 311 embriões, distribuídos em três grupos de concentração dos anticorpos, 3%, 5% ou 7%, foi identificado pela reação em cadeia da polimerase. Não houve desvio da proporção entre machos e fêmeas (P>0,05) nos grupos em que se utilizaram os anticorpos anti H-Y, quando comparadas ao grupo-controle, sem adição de anticorpos anti H-Y. Diferentemente dos resultados obtidos utilizando-se embriões bovinos produzidos in vivo, a sexagem com anticorpos anti H-Y de alto título em embriões produzidos in vitro não propiciou sucesso.In vitro produced bovine embryos at morula stage were cultured in medium containing high titer of rat H-Y antisera for 24h. The embryos were classified in two groups: 1) embryos arrested at morula stage (classified as males); and 2) embryos that developed and formed a blastocoele (classified as female). The sex of 311 embryos, divided in three groups of concentration of H-Y antisera, 3%, 5% or 7%, was identified by polimerase chain reaction. The results showed no difference (P>0.05) on sexual deviation in groups in which the H-Y antisera was added, in relation to control group, in which no H-Y antisera was added. In contrast with results obtained with in vivo produced bovine embryos, the sexing of in vitro produced bovine embryos with high H-Y antisera titer did not succed.CNP

    Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The sweet pepper is a solanaceous plant of American origin with large consumption in Brazil. In order to study the effects of water stress on the sweet pepper crop, an experiment was conducted in greenhouse. The treatments consisted of soil water content (100%, 85%, 70% and 55% of moisture in the soil field capacity) in a randomized block design with 6 replicates where the experimental units consisted of 16 plants. During the experiment (47, 62, 77 and 92 days after planting) levels of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (B, Cu, Fe, Mn and Zn) present in each plant fraction and the dry mass of plants for the accumulation of these determination were determined. At harvest the number, width and length of fruits from each plant were obtained. Variables were subjected to Tukey test at 5% probability. The water content in the soil interfered significantly with productive variables. To the accumulation of nutrients in the dry matter (leaf + stem) the elements with higher absorption are ordered as follows: K> N> Ca> Mg> S> P and Fe>Mn> Zn> B> Cu. © 2016, Universidade Estadual Paulista - UNESP.
