Estimou-se a divergência genética entre cinco genótipos de melão rendilhado (Cucumis melo var. reticulatus Naud.) (JAB-20, JAB-21, JAB-22, JAB-23 e 'Bônus nº 2') e determinou-se qual a contribuição relativa das 16 características avaliadas [nº médio de flores masculinas, hermafroditas/planta; produção total de frutos/m², peso médio dos frutos comerciáveis; diâmetro médio transversal e longitudinal do fruto (DMTF e DMLF); diâmetro médio transversal da inserção do pedúculo (DMTP); espessura média do mesocarpo e epicarpo (EMM e EME); diâmetro médio longitudinal e transversal do lóculo (DMTL e DMLL); proporção da cavidade (PC); desprendimento de sementes (DS); teor de sólidos solúveis totais (SST), pH e acidez titulável (AT)] na divergência genética. Obtiveram-se dois grupos de similaridade: I- JAB-20, JAB-21 e 'Bônus nº2' e II- JAB-22 e JAB-23. As características DMLF, DMTP, DMLL, DS e SST foram as que mais contribuíram para a divergência genética entre os genótipos.

Descrevem-se os aspectos clínicos da dilatação cística do úraco e uroperitônio em cinco touros. Os animais apresentaram, em datas distintas, distensão abdominal e diminuição da ingestão de alimentos e água, até culminar com inapetência, cerca de duas semanas após o aparecimento dos primeiros sintomas. Ocorreu distensão abdominal bilateral progressiva, que, no início do processo, era discreta e restrita ao quadrante inferior do abdômen; com cerca de duas semanas de evolução, o abdômen assumiu forma arredondada semelhante à pera. Observou-se bruxismo, atonia ruminal e desidratação. A abdominocentese revelou a presença de líquido amarelado com concentração de ureia superior a 200mg/dL. A concentração de ureia no soro sanguíneo variou de 220 a 280mg/dL e a creatinina de 65 a 82mg/dL. A ligadura do divertículo do úraco próximo ao vértex da bexiga foi eficaz nos quatro touros operados

O objetivo deste trabalho foi avaliar a produção e a qualidade dos frutos da goiabeira 'Paluma' com cinco anos de idade, submetida a podas drásticas, em diferentes meses, na Fazenda Experimental São Manuel FCA/UNESP, Campus de Botucatu-SP. O delineamento experimental foi o inteiramente casualizado, com quatro tratamentos e dez repetições, com uma planta útil por parcela experimental, completamente rodeada por quatro plantas na bordadura. Os tratamentos corresponderam aos seguintes meses de poda: T1: sem poda (testemunha), T2: poda em agosto, T3: poda em setembro e T4: poda em outubro. As características avaliadas foram: número, peso médio, diâmetros longitudinal e transversal dos frutos, produção por planta, produtividade, teores de sólidos solúveis (SS), acidez titulável (AT), relação SS/AT e pH. Com relação ao número de dias entre o início e o final das colheitas (período produtivo), observou-se que a poda, independentemente da época, favoreceu o aumento do intervalo de produção. As goiabeiras submetidas à poda em agosto apresentaram maiores valores de número médio de frutos (385) e de produção por planta (58,82 kg planta-1), diferindo das outras épocas. Os teores de sólidos solúveis, acidez titulável, pH e relação SS/AT dos frutos não foram influenciados pelas épocas de realização da poda.

O plantio de mamona (Ricinus communis L.) através de mudas pode ser uma alternativa para um melhor aproveitamento da curta estação chuvosa do semi-árido brasileiro, porém ainda não se dispõe de informações básicas para o emprego desta técnica. Na formulação de substratos para produção de mudas de mamona, as características físicas, principalmente a aeração, são fatores de grande importância. O presente estudo objetivou avaliar a composição de substratos utilizando misturas de solo, esterco bovino, casca de amendoim, mucilagem de sisal, bagaço de cana e cama de frango. Utilizou-se delineamento em blocos casualizados com 12 tratamentos e quatro repetições. Sementes da cultivar BRS Nordestina foram semeadas em sacos plásticos de 17 x 28cm, contendo misturas dos materiais a serem testados. Valores de altura, área foliar, número de folhas e diâmetro caulinar foram registrados semanalmente entre 15 e 43 dias após a emergência. Na última coleta também se registraram a massa seca da parte aérea e das raízes. O substrato composto por solo + casca de amendoim + cama de frango + mucilagem de sisal propiciou o melhor crescimento das mudas. A cama de frango contribuiu para o enriquecimento químico do substrato, enquanto a casca de amendoim e a mucilagem de sisal contribuíram para adequar as características físicas de aeração e retenção de água.

Blood pressure and vascular reactivity to phenylephrine (hypertensor) and sodium nitroprusside (hypotensor) was determined on male broilers taken from 5 commercial strains (Arbor Acres, Cobb, Hubbard-Peterson, ISA and Ross), with 21-28 days of age. Blood pressure was measured in the femoral artery by introducing a cannula attached to a pressure transdutor and recorded on a polygraph. Hyper or hypopressor substances were injected via jugular vein at 5, 10, 20 and 40-mcg kg(-1) body weight. No differences in the systolic, diastolic and mean blood pressure and no significant blood pressure responses to phenylephrine and sodium nitroprusside were observed among strains. Throughout strain and treatment blood pressures (systolic, diastolic and mean) were high in both experiments. This suggests that these modern male broilers have high arterial pressure possibly due to an indirect selection effect.

In this paper we report a study on research in the field of History in Mathematics Education conducted in Brazil in the last five years. We evaluate studies that are theoretical or report experiences on the support found in history that can contribute to the situations of teaching and learning of mathematics, based on the Proceedings of Seminarios Nacionais de Historia da Matematica and Encontros Luso-Brasileiros de Historia da Matematica. Examining the interests, directions and focus of research in the field, we found that the vast majority of studies address specific issues of History of Mathematics, and the number of studies on History in Mathematics Education is still very low. We note that, in the last five years, the arguments in favor of the teaching potential of the History of Mathematics, which is very present in the speech of teachers and managers of public education, has not yet been materialized in experiments or investigations to promote this link effectively.

The Influence of Drying Temperatures on the Yield Composition of Citronella (Cymbopogon winterianus Jowitt) essential oil. The studies were carried out to establish more precise parameters for citronella (C. winterianus Jowitt) post-harvest, and to optimize drying time and essential oil quantitative/qualitative yield. Five treatments were designed (30°C, 40°C, 50°C, 60°C and 70°C), with 14 repetitions of the drying process and 12 of the essential oil extraction. Drying at 60°C gave the best results for drying time (48 hours until weight stabilization), and also for extracted oil quantity (1.228 ± 0.127% over dry weight). Essential oil content showed high quantitative variations. The main compound found was neral, except in the 50°C treatment, where citronelal was the main compound.

With the development of greenhouse grown crops, the whitefly Trialeurodes vaporariorum (West.) has become an important pest. Aiming at verifying the effect of host on the development of this species, the biology of the whitefly was studied on bean (Phaseolus vulgaris L.) cultivars IAC-Carioca Pyatã, IAPAR-57, Jalo Precoce, IAC-Bico de Ouro, IAC-Maravilha and on soybean (Glycine max L.) cultivar Cristalina. The study was conducted at the Laboratório de Entomologia Agrícola - FCA-UNESP, at 25 ± 3°C temperature, 80 ± 10% RH and 14h photophase. The biological parameters assessed were duration, viability and number of nymphal instars; male and female longevity, oviposition period, number of eggs per female and sex ratio; egg viability and incubation period and the life cycle duration. Based on data obtained, fertility life tables were constructed to allow a comparative analysis of the effect of cultivars on the biological development and consequent population growth of this species. The bean cultivars IAC-Maravilha and Jalo Precoce negatively influenced T. vaporariorum development, whereas, the other bean cultivars studied, as well as the soybean cultivar Cristalina, provided good conditions for development of this pest.

The main causes of illness and consequent death in patients affected by Diabetes Mellitus are the long-term complications. Depression can make it harder to control the level of glucose in the blood, as well as intensifying and worsening the clinical complications, thus reducing the quality of life. The aim of this study was to estimate the incidence of Diabetes Mellitus in Public Health Clinic in Presidente Prudente (SP) in patients enrolled in the Hiper-Dia Program. From October 2003 to July 2004, a descriptive survey was carried out. Data were obtained from doctor's records of 50 diabetes patients and also their answers to a specific questionnaire. The majority of the patients were female, had not completed elementary school, with a family income below five minimum wages, a nationally-defined amount related to the poverty line. It was observed that 24% of the patients had depression and 76% never followed a controlled diet. Pharmacological treatment was prescribed for 82% of the patients. Twenty-eight patients were receiving psyicological treatment, together with oral hypoglycemic agents. The glycated hemoglobin was measured in 68%. The association between depression and submission to treatment was not significant. No statistical association was found between the psychologically assisted patient's group and glucose control (p= 0.40), diet control (p= 0.37) and physical activities (p= 0.77). It was concluded that 24% patients had depression and the majority not under diet control, but 82% were under pharmacological treatment.

The harvest is a critical time in the production of the peanut (Arachis hypogaea L.), however in this operation losses are inevitable, in some cases o f up to 30% of production. Peanuts are grown for a short period during the reform of the sugarcane fields, providing better usage of the agricultural spaces in Jaboticabal, São Paulo. The objective of this research was to see how early the peanuts could be dug up once they are seen to have matured. The peanuts were dug up at 120, 125, 130, 135 and 140 days after sowing. Results were subjected to variance analysis by the F-test, and when there was significance of the averages, the Tukey test at 5% probability was applied, using a box plot for the following variables: maturation, moisture content of pods and soil, mechanical resistance of soil to penetration, harvest loss and productivity. The box plot proved efficient in the univariate evaluation of the analyzed variables, creating excellent conditions for viewing their behavior. Digging up the peanuts at 120 DAS is recommended.
