26. Ação de produtos químico in vitro, em mudas e em campo sobre a mancha bacteriana (Xanthomonas perforans e X. gardneri) em tomate para processamento industrial / Chemical control of the bacterial spot in tomato for industrial processing: sensibility in isolated vitro and efficiency of products in seedlings and in field
The search of alternative products for tomato bacterial spot has been promoting by the lack of effectiveness registered by the traditional products available. The objective of this work was to evaluate a range of chemical products by in vitro tests, in experiments seedlings and field experiments. The products studied were: acibenzolar-S-methyl; benzalkonium

27. Diversidade populacional, vias de transmissÃo e virulÃncia de Streptococcus agalactiae isolados de tilÃpias do Nilo (Oreochromis niloticus). / Tilapia; Brazil; Streptococcus agalactiae, experimental infection;16SrRNA; ISR
Streptococcus agalactiae is an emerging pathogen in Nile tilapia. To investigate aspects of the epidemiology, transmission, virulence and the genetic diversity of S. agalactiae infections, nine outbreaks of meningoencephalitis and septicemia in Nile tilapia farms in Brazil were analyzed. The 16S rRNA gene and ISR were utilized with molecular marker of the ge

28. Characterization of the dent and flint corn fractions with different particle sizes and evaluation on the quality expanded extrudes / Caracterização das frações com diferentes granulometrias de milho dentado e duro e avaliação na qualidade de extrusados expandidos
The endosperm of a corn grain is made up of a vitreous region and a farinaceous region, which present different chemical and physical composition. Corn fractions obtained by dry milling, presenting different particle sizes distributions and variations in chemical composition, are used in the production of expanded extrudates (snacks). The objective of the pr

29. Aceleração da consolidação em solos tropicais com drenos condutores elétricos / Acceleration of consolidation on tropical soil with electro conductor drain
The electrokinetic method has been studied by a growing number of research centers, in application such as mining engineering, civil and environmental engineering, food and sports. To meet the application needs it was necessary to develop a new technology that combines a variety of materials, functions and processes for the implementation of specific activit

30. EvoluÃÃo das caracterÃsticas morfoanatÃmicas nos ciclos de seleÃÃo do milho âSaracuraâ sob encharcamento intermitente / Evolution of morpho-anatomicals characteristics on selection cycles of maize (Zea mays L.) âSaracuraâ â BRS â 4154 under intermittent soil flooding
Although every single plant needs a certain amount of water, the excess around roots can cause severe injuries and even death of most crops. Soil flooding is one of the most important factors which affects maize crop production and development on tropical and subtropical regions. Excess of water blocks the oxygen transfer and others gases from soil to atmosp

31. Nitrosilo complexos de rutênio : síntese, caracterização e avaliação de suas potencialidades citotóxicas / Nitrosyl ruthenium complexes : synthesis, characterization and evaluation of its cytotoxic potentialities
The behavior of nitric oxide (NO) in biological systems has been under intense investigation in recent years in view of its possibly crucial role in a variety of physiological processes. Great progress in this area has been achieved by studying nitrosyl transition metal complexes. In this sense ruthenium complexes are by far the most studied and their relati

32. Quality of glyphosate-tolerant soybean seeds produced in Sacramento (MG) / Qualidade da semente de soja tolerante ao glifosato, produzida em condições favoráveis
This work has aimed to evaluate the quality of glyphosate-tolerant seeds of soybean genotypes of early, mid-, and late season, produced in adequate conditions. Experiments took place in two phases. Firstly, in a field one, with three variety competition trials; 6 glyphosate-tolerant genotypes of soybean were evaluated: early season (BR01-71210, BR02-64301, B

34. Influência de uma cultura startertermofílica sobre a viabilidade de Lactobacillus acidophiluse as características de queijo minas frescal probiótico / Influence of a thermophilic starterculture over the viability of Lactobacillus acidophilusand textural, sensorial, and related properties of probiotic Minas fresh cheese
Functional foods are foods that claim to promote human health over and above the provision of basic nutrition. Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, improving his intestinal microbial balance. Lactobacillus acidophilus strains have been shown to be able to survive at favorable con

35. Avaliação de parametros do processo de extrusão e do teor de farelo de trigo adicionado em caracteristicas de "snacks" expandidos de milho. / Evaluation of extrusion process parameters and of wheat bran content added on features of corn expanded snacks.
Expanded extruded snacks present great acceptance, especially among children and adolescents. Therefore, the development of fiber enriched snacks represents a mean for the introduction of dietary fiber into the diet. The ingestion of fibers has functional benefits; the reduction of the risk of several diseases, highlighting: colon cancer, diabetes and cardio

36. Changes in the biogenic amine content of the prefrontal cortex, amygdala, dorsal hippocampus, and nucleus accumbens of rats submitted to single and repeated sessions of the elevated plus-maze test
It has been demonstrated that exposure to a variety of stressful experiences enhances fearful reactions when behavior is tested in current animal models of anxiety. Until now, no study has examined the neurochemical changes during the test and retest sessions of rats submitted to the elevated plus maze (EPM). The present study uses a new approach (HPLC) by l
