Chemical inhibition of the contaminant Lactobacillus fermentum from distilleries producing fuel bioethanol

The purpose of this study was to determine the Minimum Inhibitory Concentration (MIC) of pure or mixed chemicals for Saccharomyces cerevisiae and Lactobacillus fermentum in the samples isolated from distilleries with serious bacterial contamination problems. The biocides, which showed the best results were: 3,4,4' trichlorocarbanilide (TCC), tested at pH 4.0 (MIC = 3.12 mg/l), TCC with benzethonium chloride (CBe) at pH 6.0 (MIC = 3.12 mg/l) and TCC mixed with benzalkonium chloride (CBa) at pH 6.0 (MIC = 1.53 mg /l). If CBa was used in sugar cane milling in 1:1 ratio with TCC, a 8 times reduction of CBa was possible. This formulation also should be tested in fermentation steps since it was more difficult for the bacterium to develop resistance to biocide. There was no inhibition of S. cerevisiae and there were only antibiotics as an option to bacterial control of fuel ethanol fermentation by S. cerevisiae.

Avaliação comparativa das perdas de água por evapotranspiração em mesocosmos colonizados por diferentes macrófitas aquáticas

Water loss increase through evapotranspiration is one the most important modes of interference of weeds in water bodies, especially in water storage reservoirs. Thus, this research was conducted to compare the water losses in mesocosms colonized with the aquatic weeds Myriophyllum aquaticum,Brachiaria subquadripara,Echinochloa polystachya,Typha latifolia and Pontederia lanceolata. The evaluations were carried out in July 2004, in three 4-day periods. The water losses were evaluated based on the amounts of water necessary to restore the existing water level before each evaluation period. The colonization of the aquatic weeds increased the water losses in the mesocosms, with the highest losses being observed in those colonized by T. latifolia, between 3.54 to 4.71 times the water surface without aquatic weeds. The losses in the mesocosms colonized by M. aquaticum,B. subquadripara, E. polystachya, and P. lanceolata were statistically similar and promoted increases between 1.54 to 2.21 times the free surface. The results showed that aquatic weed control is important to prevent water losses in reservoirs used for water storage.

A formação de professores para a educação Inclusiva: alguns aspectos de um trabalho colaborativo entre pesquisadores e professores da Educação Infantil

To contribute to formation of Childhood Education teachers for the Inclusive Education, this article had as its central objective describe how it was addressed the issue of learning difficulties and the impact of misdiagnosis assigned to a child in the initial phase formal learning of writing, in one of the theoretical-reflective meetings undertaken with 43 teachers for Pre II, of the ten schools of Childhood Education of the state of São Paulo. Such a description was guided through the of the collaborative approach taken subproject “understanding about the clinical diagnosis of dyslexia and its impact on the educational future of children enrolled in classes II Pre Childhood education”, developed as one of the phases and as part of larger project called “depathologization of the learning of the writing and Inclusive Education: Reflections and actions of the professor of Childhood Education”. At the and, was possible the identification by the reports arising from the participation of teachers mentioned, the need to resignification their didactical experiences for the systematization of new actions aimed at coping with learning difficulties that pervade the process of appropriation writing of the students, which may contribute to depathologization of the school environment to the extent that teachers can assist students in building a more positive relationship with writing, rather than adopting rigid and restricted procedures that do not consider the relationship of each subject with writing and the singularities present in this relationship.

Estudo da fluência dos aços inoxidáveis ferríticos estabilizados ao titânio e nióbio e simulação numérica do processo no abaqus

The purpose of this research was tested a finite element model (FEM) that represented the creep of a slab during the reheating process of hot rolling. The aim is to prevent creep phenomenon changing the reheating profile with hot tensile test in Gleeble 3500, and, also, understand the former defect crisis. The goal of this work is to have a predictive tool to optimize the reheating process changing parameters (length and thickness). Then, use input parameters obtained from the tests to approximate the solution of the problem aided by Abaqus CAE. The results have showed that the ferritic stainless steel AISI 409 has a lower sensitivity to creep comparing to the stainless steel AISI 409, AISI 430Ti, AISI 441 and AISI 444

Conselho Tutelar de Rio Claro: um panorama dos casos registrados no ano de 2007

Este trabalho tem como objetivo levantar o número de casos encaminhados ao Conselho Tutelar de Rio Claro no ano de 2007, caracterizar os motivos e as queixas que originaram esses encaminhamentos, verificar as orientações dadas pelos Conselheiros e mapear os bairros da cidade que foram atendidos pelo Conselho. O trabalho está baseado em pesquisa bibliográfica, análise das planilhas que são preenchidas mensalmente e dados coletados em entrevistas realizadas com duas Conselheiras Tutelares. Foi constatado que o Conselho Tutelar de Rio Claro registrou, naquele ano, 227 casos, sendo 441 novos, 597 retornos e 189 acompanhamentos de casos. As queixas registradas são as mais diversas, indo de violência sexual até requisição de certidão de nascimento. Predominam queixas de evasão escolar e reiteração de faltas, seguida pelas de maus tratos e comportamental. Com relação às medidas aplicadas pelos Conselheiros à criança ou adolescente, predomina aquela relativa à matrícula e freqüência obrigatória em estabelecimento oficial de ensino fundamental. Já no que diz respeito às medidas aplicadas aos pais ou responsáveis, a medida de maior registro foi a de orientação, seguida pela de obrigação em matricular filho e acompanhar sua freqüência e aproveitamento. Verificou-se também que não somente os bairros periféricos da cidade são atendidos pelo Conselho Tutelar, mas também bairros considerados de classe média e alta.

Two new species of tarsonemid mites (Acari: Tarsonemidae) from northeastern Brazil

Two new species of tarsonemid mites, Daidalotarsonemus annonae sp. nov. and Fungitarsonemus setillus sp. nov. found on Annonaceae leaves collected in northeastern Brazil are described and illustrated. Females of D. annonae are similar to those of D. serissae, but differ by having setae c2 setiform, and seta 1a distant from apodeme 1. F. setillus is similar to F. pereregrinus, but females can be distinguished by having the prodorsal shield fused to tergite C, dorsal setae h and d short, and setae c1 longer than c2.
