Q field experiment was carried out at the Gralha Azul Experimental Farm/PUCPR, in the municipality of Fazenda Rio Grande-PR, to evaluate the effect of different times and coexistence extension periods of weeds interfering in corn yield. The experiment was arranged in a complete randomized complete block design and the treatments in a 4x5+2 factorial, with four replications. The treatments were as follows: four initial weed control periods (0-0, 0-7, 0-14 and 0-21 DAE) and five restarted weed control periods until the harvest (28, 42, 56, 70 and 84 DAE) and two checks, weedy and weed-free. The experiment was carried out under a no-till system. The period prior to weed interference (PBWI), the start of the critical period of weed interference (CPWI) and the infesting community were evaluated. When the initial weed control period was 0-0 day, the PPWI was at 9 DAE of corn; however, with increasing initial weed control periods (0-7, 0-14 and 0-21 DAE) the period prior to weed interference inncreased in relation to 0-0 day of the initial weed control, evidencing the existence of PPWI-S of 17, 24 and 28 DAE of corn, respectively. Thus CPWI initiates at the end of PPWI-S, the period when weed control is indispensable to prevent a significant reduction in corn yield. Coexistance with the weeds throughout the crop cycle reduced yield in 15%, compared to the weed-free check. Nine species of seven botanical families were assessed in the infesting community. Reduced density and dry mass were verified in the weeds that coexisted with corn, compared to those that grew without it, thus evidencing a suppressive effect of corn over the infesting plants.

Introduction: The myofascial pain syndrome (SDM) is one of the most common causes of musculoskeletal pain. One of the possible treatments for SDM is the type of physiotherapy myofascial manipulation. Objective: This study aimed to analyze the effect of manipulative technique with myofascial pain threshold before and after applying the technique in athletes during competition period. Methods: Participated in the study 62 subjects of both genders, aged between 14 and 38 (19.64 + 4.89), who had myofascial pain syndrome, 32 oh the treatment group and 30 divided equally between control group and the placebo group. All were athletes and operated by the Department of Sport and Leisure in the city of Marilia – SP and were in competitive period. The volunteers were evaluated according to their musculoskeletal symptoms to prove the necessity of performing the technique of myofascial manipulation. Confi rmed the need to assess the pressure pain threshold (LDP) using a digital dynamometer. After the measurement, patients underwent treatment or using the technique of myofascial manipulation, or a sliding surface for the placebo or no treatment for the control group followed by the immediate reassessment of the LDP. Results: The results were normalized by Kolmogrov-Smirnov test (KS). Through the ANOVA test found no differences between the initial LDP thresholds between groups. To compare pre and post LDP of the three groups we used the paired t test. Signifi cant difference (p=0.0001) between the values of pain threshold before and after application of myofascial manipulation for the treated group and not signifi cant for the control group (p=0.45) and placebo (p=0.16). Conclusion: We conclude then that the myofascial manipulation technique is able to increase pain threshold after micro-musculoskeletal injuries in athletes in competitive period.

This research aimed do verify the contribution of the games of rules to the development and learning of the mathematics of a philantropic institution for preschool children – Centro de Educação Infantil Santo Antônio (CEISA) - from March to September 2010. The overall universe comprehends one teacher, one class auxiliary, one trainee, the organization teaching coordinator and twenty six students. The main objective was to explore games as a strategic resource for the development and learning, by searching auxiliary contributions for teaching the mathematics, and ways to wake and keep the interest of the students for the games as tools of development and learning; to identify important points for such development and learning by using games; to detect the difficulties of the students in the process of teaching-learning mathematics; to use games as a moment for fun; to show the teachers the possibilities of using ludic materials as methodic resources and to make interventions, by means of the games, to enhance the process of teaching-learning the matematics, through a qualitative approach, using the interview as instrument by means of an observation and study of case

The object of this study was assess through pre-clinical tests, the possible diuretic activity and the effects on the mean arterial pressure of the aqueous and ethanolic extracts of branches of “bugre”, Hedyosmum brasiliense Miq., species used in the treatment of renal and urinary disorders The tests were made in males anesthetized Wistar rats and randomly distributed into 4 experimental groups: Group I – Water control, group II – treated with aqueous extract (EA) of “bugre”, Group III – water control + “tween 80”, group IV – treated with ethanol extract (EE) and “bugre”. All groups were subjected to experimental protocol, composed of three periods: Balance (40 minutes), Basal (30 minutes) and Experimental (90 minutes), occurring the urine collection every 30 minutes, from the basal period and measuring blood pressure every 10 minutes. The results presented validate the ethnobotany indication of the use of H. brasiliense tea in the treatment of renal problems, because increased significantly the urinary flow in anesthetized Wistar rats (diuretic effect), without changing significantly (p>0,05) the arterial pressure

The oil market is not a common market, and its complexity increases dramatically when considering the strategic and geopolitical involved, thus resulting in large uncertainties and concerns. The attempt to control prices has always been a challenge for the major world powers, since the increase in oil prices benefits the exporting countries, but harms importers, especially those regarded as less developed. Understand and try to predict some strategies adopted up the oil crises is one of the main points of the research, in order to demonstrate how economics can be used as an instrument of power and domination between nations, and how plans and strategies and rearrangements of supply and demand favor the growth of this economy, especially in the current period, with the new Brazilian oil era, beginning with the discovery of pre-salt, amid a context of growing need for the use of oil and its derivatives

Este trabalho teve como objetivo principal avaliar a influência de um período de chuvas intensas sobre as assembléias zooplanctônicas e variáveis limnológicas dos reservatórios de Chavantes e Salto Grande. Em função das precipitações elevadas, o tempo de residência da água durante o período de verão 2009/2010 (período imediatamente anterior às coletas) foi o mais baixo da década (1999-2010), tanto para Chavantes como para Salto Grande. As variáveis analisadas foram: transparência, temperatura, oxigênio dissolvido, pH, condutividade elétrica, turbidez, material em suspensão, clorofila a e nutrientes (nitrogênio total, fósforo total e silicato dissolvido). A turbidez foi a variável que mais se alterou, apresentando um aumento notável com o incremento das chuvas. A transparência e o material em suspensão também apresentaram grande alteração, sendo que a primeira variável diminuiu com a maior quantidade de chuvas e a segunda aumentou. Os valores de fósforo total e silicato dissolvido diminuíram com o aumento das chuvas, sendo que para o silicato a variação foi mais expressiva e para o fósforo o decréscimo foi mais acentuado em Chavantes do que em Salto Grande. Para as outras variáveis limnológicas, bem como para o zooplâncton, os dois reservatórios apresentaram comportamentos diferentes quanto às alterações pluviométricas. A temperatura variou mais em Chavantes. Condutividade elétrica e pH apresentaram relação com a temperatura e o oxigênio dissolvido não teve muita alteração com as mudanças pluviométricas. Os atributos analisados para o zooplâncton foram riqueza, composição, abundância (total, por táxon e das fases de desenvolvimento) e diversidade. Comparando os dois reservatórios estudados, foi observado que em Chavantes o aumento pluviométrico teve efeito muito ...(Resumo completo, clicar acesso eletrônico abaixo)

o estudo faz uma avaliação do conhecimento das gestantes à respeito de alguns aspectos do planejamento familiar, gestação, parto e amamentação. Trabalhando na saúde pública, particularmente com gestantes foi observado certa ansiedade e insegurança por parte delas, além da falta de conhecimento à respeito desse período. Objetivo: diagnosticar o nível de conhecimento das gestantes da Unidade Básica de Saúde Boa Vista, em Limeira, visando à melhora do atendimento de gestantes. Metodologia: a pesquisa é do tipo mista, isto é, com abordagem qualitativa e quantitativa. A metodologia para coleta de dados foi a entrevista semi-estruturada, com vinte cinco gestantes sobre o conhecimento e a experiência quanto ao planejamento da gravidez, métodos anticoncepcionais, acompanhamento pré-natal, parto e amamentação. Resultados: os resultados indicaram que a maioria das gestantes não teve sua gestação planejada, embora todas conhecessem algum método e parte delas fizesse uso. Quanto ao acompanhamento pré-natal, a totalidade explicitou um número de consultas necessárias dentro do recomendado pelo Ministério da saúde que é 6 consultas durante a gestação. Já em relação aos exames necessários o resultado apresentou fragilidades, pois a maioria citou desconhecer a importância de todos os exames. Quanto aos cuidados durante a gravidez, eles estiveram relacionados à alimentação e ao esforço físico, sendo as atividades sexuais mantidas dentro da rotina. Sobre o parto, a totalidade demonstrou ter conhecimento dos partos normal e cesárea e a maioria deseja ter parto normal, o que é muito positivo. No que diz respeito à amamentação, as gestantes reconheceram sua importância embora as justificativas, de modo geral, tenham sido restritas. Elas demonstram que desejam amamentar, no entanto, 32% delas não pretendem amamentar exclusivamente até os 6 meses. Conclusão: ...(Resumo completo, clicar acesso eletrônico abaixo)
