The use of insecticide seed treatment for soybeans is a major component in pest control at the initial stage of soybeans, as they prevent the decrease plant stand. This treatment provides it with greater security and helps ensure the productivity of the crop, besides having a much lower environmental impact compared insecticide applications by air. With the large scale soy production in Brazil and abroad, some pests that are not the culture in question may start seeing it as a new source of livelihood. The main objective of this study was to evaluate the germination, seedling size and abnormal seedlings in treatments with insecticides Semevin (thiodicarb) Hurracan (Fipronil), Imitra (Imidacloprid) and Acetra (Acephate), the dosages recommended by manufacturers. Evaluations of physiological seed quality were conducted by means of germination, seedling size and abnormal seedlings in sand substrate, with the CD 202 variety of high germination and vigor. To avoid any discrepancies between the treatments all tests were used Firewalk fungicide (Thiram + Carbendazin). Treatment with insecticide Hurracan (Fipronil) proved to be superior to other insecticides because of its proximity to the witnesses and the significant difference by Tukey 5% of the other tests...

Due to the great importance of soybean in Brazilian agriculture generating frontiers and increasing exportations, the use of quality seeds becomes a fundamental necessity, since this insume carries the desirable characters that result in higher productivity each harvest. This study case has the objective of evaluating losses in the soybean seed production of Sementes Petrovina Company, located in the state of Mato Grosso, during different steps of seed conditioning. Data were collected from discharges of pre-cleaning, post-cleaning, spirals separator, and gravity table of 3 cultivars, comparing/contrasting the results of 4 different crops. Data vary from crop to crop inside each cultivar mainly in relation to the discharge generated by the spirals separator, which is attributed to the form of the seeds, and the cultivar development during the rain period of each crop. The spirals separator was responsive for the largest fraction of discharge, representing half of the total discharge originated by the cultivar. It is suggested disusing this equipment when of high quality seeds, and grading the seeds with less than 1 mm sieves which would considerably reduce the discharge fraction lowing farmer s losses.; Devido a alta import??ncia da soja na agricultura brasileira gerando divisas e aumentando as exporta????es...

Soybean is one of the main world commodities and the seed is the key for high yields in this culture. Nevertheless, the soybean seed coat is the main modulator of seed quality, so, in this structure we could find answers for high seed quality production. The study goal is to identify structural contrasting traits, to obtain cDNA and to draw primers related to lignin synthesis and wax deposition in seed coat from two soybean genotypes. Plants were grown in greenhouse, flowers were identified and dated to follow the development after flowering until legumes were harvested (25, 30, 35, 40, 45, 50, 55 and 60 days). Seed coats were then analyzed in electronic microscopy and used to build a soybean seed coat cDNA library for permeability traits (lignin synthesis and wax deposition). In silico, analyzes were performed to obtain specific primers to detect soybean seed coat lignin and wax biosynthesis genes. According to the seed coat traits, we identified differences in the palisade cell thickness between genotypes. The protocol based on litio chloride was efficient to extract total RNA from both genotypes in all phases. The unidirectional cDNA multiplication was efficient for the generation of enough cDNA quantity for future projects. In silico analyzes allowed the development of 16 primers related to lignin and wax deposition biosynthesis in soybean seed coat.; A soja ?? uma das principais commodities mundiais e a semente o principal insumo para sua produ????o.

A sociedade da informação pode ser vista como uma organização geopolítica dada a partir da terceira revolução industrial, com impacto direto no uso da informação e das tecnologias da informação e comunicação (TICs).  O termo surge como uma mudança de paradigma técno-social presente na sociedade pós-industrial, visando o uso da informação como moeda para a sociedade em constituição naquele momento. No Brasil ganhou peso a partir da publicação do Programa Sociedade da Informação no Brasil – Livro Verde, em setembro de 2000, pelo Ministério da Ciência e Tecnologia, sendo marcada pela falta de debate na construção do documento mestre. Nosso objetivo nesse artigo é discutir a Sociedade da Informação na  contemporaneidade, além do uso ordenado e consciente da informação, buscando os conceitos-chaves para o seu melhor entendimento. Por meio de uma pesquisa bibliográfica e documental, retomamos o seu conceito, passando por questões como a inclusão-exclusão digital até o uso dos recursos informacionais digitais.; Information Society (IS) may be taken as a geopolitical organization which started at Third Industrial Revolution...

Discute questões como propriedade intelectual e industrial e diferenças existentes entre conhecimento científico e tecnológico. Busca inserir a patente no contexto da comunicação científica e tecnológica. Apresenta dados de um estudo que objetiva analisar a relação entre a informação científica e a tecnológica na produção intelectual dos pesquisadores-inventores da primeira carta-patente da Universidade Federal do Rio Grande do Sul (UFRGS). O período analisado compreende os anos anteriores à publicação do pedido da patente (1996-2000) e posteriores (2001-2005). Conclui que, no caso analisado, ocorre um fluxo entre a informação científica e tecnológica, na qual a primeira, após sua divulgação e aprovação pelos pares, subsidia a segunda. Da mesma forma, a patente gera um impacto na produção científica dos pesquisadores, ocorrendo uma retroalimentação entre ciência e tecnologia. Sugere que novos estudos sejam realizados.
