Uso da entrevista em dissertações e teses produzidas em um programa de pós-graduação em educação

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

Mobiliários adaptados para pessoas com paralisia cerebral: um levantamento das teses e dissertações produzidas no Brasil

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

Repelência e deterrência alimentar de vaquinhas por óleos de nim e cinamomo aplicados em folhas de feijoeiro

This work aimed to evaluate the repellent and deterrent effect of the application of concentrations of neem and chinaberry oil on bean leaves on the leaf beetles Diabrotica speciosa (Germar) and Cerotoma arcuata (Olivier). The concentrations of neem oil tested were 0.625, 1.25, 2.50, 5.00, 10.00 and 20,00 mL, corresponding respectively to 1, 2, 4, 8, 17 and 33 ppm of azadirachtin A and the concentrations of chinaberry oil used were the same used to neem oil, corresponding, however, to 1.875, 3.75, 7.50, 15.00, 30.00 and 60.00 mg mL(-1) of chinaberry extract, respectively. For the free-choice tests, glass containers were used as arenas, whereas for the no-choice tests Petri dishes were used, where in both one insect per treatment was released in the center. Attractiveness was evaluated in predetermined time periods, in addition to the leaf consumption, at the end of the experiment. Neem oil is repellent to D. speciosa and C. arcuata, with more efficient results at the 5.00, 10.00 and 20.00 mL concentrations. All concentrations of neem oil reduce leaf consumption of both insects, except in the no-choice test with D. speciosa, in which only the 10.00 and 20.00 mL concentrations are deterrent. Chinaberry oil provides high repellent activity on both leaf beetle species, and the 10.00 and 20.00 mL concentrations stood out. The 10.00 and 20.00 mL concentrations of chinaberry oil are deterrent to D. speciosa and C. arcuata.

Estudo da secagem natural e forçada das folhas de Corymbia Citriodora a partir da extração de óleos essenciais

Essential oils are products from plants and can be located in parts or in its entirety. There are several methods for its extraction, where the most suitable depends on the plant or the use of the essence. The main species cultivated in Brazil are the Corymbia citriodora, Eucalyptus globulus and Eucalyptus staigeriana. The Corymbia citriodora is a species that was introduced in Brazil along with other species, with the initial objective of timber production. The yield of oil can range from 0.5 % to 3.0% according to the literature and this can be optimized by reducing the moisture content of the leaves. Studies show that the lower water content in the leaves allows the vapor stream generated in the extractor can drag, more efficiently, the volatiles stored in the cells as compared with the green material. The drying of the sheets is important for companies, so that there is transport of water, increasing the volume of the sheets to distillation and hence a greater volume of oil. The objective of this study was to compare the drying methods, analyzing the income of the essence and determine the best method to optimize the yield of essential oil. Experimental tests were performed natural drying 10, 15 and 20 days and fluidized with times of 60, 90 and 120 minutes and after drying were extractions of the oil. The results obtained for fresh leave yield was 1.20 % and the drying time which showed the highest yield was 15 and 20 days with 2.90 % and 2.70 % yield, respectively, with the lowest level humidity of 16%. The yields obtained in fluidized bed drying did not change as the natural drying to between 1.64% and 1.7%. It is concluded that the decreased level of the sheets increases the yield of oil and the temperature in the fluidized bed is essential for the removal of water from the leaves necessary to increase the yield

Avaliação da atividade antibacteriana de espécies vegetais utilizadas em doenças do trato digestório: Baccharis trimera (LESS.) DC. E Casearia sylvestris Swartz

Baccharis trimera (Less.) DC. Asteraceae e Casearia sylvestris Swartz Salicaceae são plantas nativas do Brasil e de uso tradicional em doenças do trato digestório. Seus extratos e substâncias purificadas apresentaram diversas atividades farmacológicas (ex.antiulcerogênica, antimicrobiana) e baixa toxicidade. O Helicobacter pylori (bacilo gram-negativo) coloniza o estômago humano, associada ao maior risco de incidência de várias doenças (úlceras pépticas, linfomas e adenocarcinomas gástricos). Com o objetivo de avaliar a atividade antibacteriana de diferentes extratos, frações e substâncias de ambas as plantas medicinais, extratos de partes aéreas de B. trimera e de folhas de C. sylvestris foram preparados utilizando-se técnicas de maceração, obtendo-se o extrato acetato de etila e etanólico de C. sylvestris e acetato de etila, etanólico, etanol 70% e hexânico de B. trimera. Estes foram fracionados e analisados por técnicas cromatográficas. Os extratos e suas frações e substâncias foram submetidos a ensaios para avaliação da atividade antibacteriana para a determinação da concentração inibitória mínima (CIM). O método utilizado para os ensaios foi a diluição em microplacas usando as bactérias Helicobacter pylori ATCC 43504, Staphylococcus aureus ATCC 25923 e Escherichia coli ATCC 25922. A partir do fracionamento do extrato acetato de etila de B. trimera e do extrato etanólico de C. sylvestris foram obtidas oito frações distintas do EAcBt e a fração de diterpenos do EEtCs. A análise em CCD demonstrou a presença de casearina X, B e caseargrewiina F na fração de diterpenos (EFSCs2). Os extratos da B. trimera EAcBt, EEtBt e EEt70Bt e da C. sylvestris EAcCs e EEtCs apresentaram atividade anti-H. pylori, com valores de CIM de 250, 500, 500, 125 e 750 g/mL, respectivamente...
