Orchidaceae is one of the largest and diverse families of angiosperms, that is in almost every type of habitat, except tundras and deserts. They are considered of great ornamental importance, the genus Phalaenopsis has received a great prominence having increaed and its production enlarged in the Gross and inner market This way, the Brazilian floriculture market has a great demand in seedling production, requiring more studies and researches involving biotechnologycal techniques from the development of vases and containers on a prepared substrate, propagation techniques and acclimatization. And with in vitro culture, it is possible that the desirable plant coul be multiplied through several sucbultures, which enables an earlier and new cultivation available more quickly for commercial use. The luminosity is another factor that is gaining prominence in the productivity of orchids, the fact that the quality of light affects directly the growth and development of plants grown in vitro and/or ex vitro. The present work had as objective to anlyze the growth of in vitro and acclimatization in the two cultivations (cv. 6323 and cv. 6546) of orchid Phalaenopsis amabilis Blume, under different lighting spectra. Inicially it occurred the sowing the seedling in the cultivation enviroment MS that were enveloped with different cellophanes: yellow, blue, Green, red, and white. After 60 cultivation days it was performed an statistical evaluation on the seedling. Afterward, they were put in collective vases to the phase of acclimatization, and those ones stand for more three months. Through analyze the biometric data it can be observed that the growing in vitro and ex vitro of Phalaenopsis amabilis was influenced by many different spectra lights, considering that the various results of this influence from the genotype. It can be observed that the blue spectrum performed a great performance on cv. 6323 and on the Green spectrum cv. 6546.
Uma versão abstrata do teorema de Cauchy-Kowalevski

Our main goal in this work is to present an abstract version of Cauchy-Kowalevski theorem and use it to solve the periodic Cauchy problem for the Camassa-Holm equation.
Educação das relações étnico-raciais: contribuições de cursos de formação continuada para professoras(es)
(Universidade Federal de São Carlos, 2013-08-22) Luiz, Maria Fernanda; Silva, Petronilha Beatriz Gonçalves e; https://lattes.cnpq.br/3484454478374641
This research investigates the contributions for changes (or not) in the pedagogical practices of teachers of the early years of basic education stemming educational processes triggered in training courses relating to ethnic-racial theme. From the implementation of the law 10.639/032, topics related to the history and culture african- Brazilian and African became compulsory in the curriculum of public and private networks, which creates demand for conducting continuing education courses for teachers of different levels of education in these operating systems. Thus, were invited to participate in this study, black and non-black teachers in the early years of basic education who have participated in continuing education courses related to ethnic-racial theme. The research data were collected through in-depth conversations held with these teachers. The relevance of this study to the field of education is confirmed by the possibility of reflection on points that continuing education courses contributed or not to change the practice of these teachers, issues that need to be rethought in formulating future courses as well as the influence of subjective questions pertaining relating to the experiences of teachers and influence the understanding and coherency of the theme.
