Supressão de água em diferentes fases fenológicas do feijoeiro (Phaseolus vulgaris L.)

Bean (Phaseolus vulgaris L.) is widespread in the Brazilian social and economic scene. The hypothesis is that if the water supply is suppressed in just one of the five development stages of irrigated beans, it can result in yield reduction lower than 20%, allowing water economy. The objective of this study was to compare the performance of bean Carioca group IAC Alvorada yield components, with irrigation suppression in each of the five phenological phases (emergence, vegetative, flowering, grain filling and maturation) and no irrigation and irrigated in all stages. The study was conducted at Agronomical Sciences College, UNESP, Botucatu, SP, Brazil. The statistical design was the randomized block with seven treatments and four replications. Data were subjected to analysis of variance and t test at 5% probability. A rainfall event (58 mm) after planting allowed the successful emergence of seedling beans in plots where water would not be applied. The yield components were higher affect when there was irrigation's suppression at Vegetative phase and at Flowering phase. The treatments where occurred irrigation suppression at Maturation and at Emergence showed yield reduction of less than 20%, proving the hypothesis.

História da Matemática em contextos da Educação Matemática: contribuições do GPHM

In this article we tried to show the paths outlined during the past years by the Research Group on History of Mathematics and/or its relations with Mathematics Education (GPHM) at UNESP in Rio Claro - Brazil, as well as the contributions we believe we have made to Mathematics Education. The group's production has focused on issues that address the history of institutions and characters, linked to the history of disciplines, concepts and learning materials. Also, in broader terms of mathematics education, this article presents results from research that supports the understanding of teachers' conceptions about the use of History of Mathematics in the classroom; material on the history of mathematics accessible to the teacher; the presence of the history of mathematics in textbooks; proposed introductions of real numbers; and the subject of Analysis in teacher education and training.

Entre a Amnésia e a Vontade de nada Esquecer: notas sobre regimes de historicidade e história oral

In this paper we intend to sketch a configuration of the research practices of the Research Group Oral History and Mathematics Education (GHOEM) and, in general terms, to explain some concepts and procedures in which these practices are founded. In order to do this, the expression Regimes of Historicity - meaning the different ways of articulating the notions of present, past and future - is initially mobilized. By this expression we are able to understand the emergence of the discourse that underpins a set of actions and theoretical frameworks for the research in Mathematics Education and more particularly, for the Historiography of Mathematics Education.

Farelo de algodão em rações para suínos nas fases de crescimento e terminação

Forty-eight pigs with 63 day olds and average weight of 23.40±1.3 kg, were allotted in a randomized block design with three treatments(0%, 10% and 20% of cottonseed meal (FA) in diets) and eight replicates with two pigs (one barrow and one gilt). The blocks were used to control changes in initial body weight. Experimental period was the growth phase (63 to 106 days old) and growing-finishing (63 to 147 days old). In each phase the diets were isonutritives, varying however the levels of crude fiber. The levels of cottonseed meal (FA) did not affect (p>0.05) the performance of animals during the growth phase or during the total period of evaluation (growingfinishing). The qualitative parameters of manure indicated that the FA determined decrease in the nitrogen and phosphorus content, but only in the growth phase. In the finishing phase the increase in the FA inclusion promoted an increase in dry matter content. Although FA can be used in up to 20% in diets for pigs in the growing and finishing phase, it is necessary to include L-lysine and soybean oil which causes an increase in cost per kg produced pig.

Morfologia do epidídimo de cobaio (Cavia porcellus) em diferentes fases do desenvolvimento pós-natal

The morphological evolution of the epididymal duct of guinea pigs (Cavia porcellus, L.) was studied on 10, 20, 30, 45, 60, 70, 90 and 100 days of age, being complex, which is due to the proper differentiation postnatal in the epididymal epithelium. Thus, it was observed that the initial segment of the epididymis reveals an increase of epithelial height corresponding to the average height of the main tubular epithelium cells, generally progressive after 45 days of age. The epithelial height in the middle segment were higher in younger stages (10 to 45 days) than in the prepubertal age (60 days), and have a decrease among 70 to 100 days of age. The ductular terminal segment starts a gradual decrease of the epithelial heights from puberal age (70 days), until adult age (90 to 100 days). In addition, this segment showed epithelial waviness that disappeared after 70 days of age, when the lumen fills it with sperm and cellular exfoliation. The cell types of the epididymal tubular epithelium, principal cells, basal cells and apical cells, were observed in all ages. In the epididymis of very young animals, there was a predominance of undifferentiated columnar cells. After 20 days of age, there was natural prevalence of the principal cells on other cell types, what is a feature similar to other mammals.

Memórias de um profissional de história

Within the proposed framework for this issue of the journal História da Historiografia, the present article is a concise report on the trajectory of a university professor of history. The author writes on the obtainment of his degree at the USP, his participation in the beginning of undergraduate and graduate courses in the interior of the state of São Paulo, including the experience of taking part in the beginnings of the public university Universidade Estadual Paulista (UNESP). The author also discusses aspects of his academic and institutional life, and reports on the process of his insertion in an established historiographical line of work. It can be introductorily noted that the reader will not always find a linear chronological order, due to the multifaceted nature of the activities of a university professor of history. An additional note is that I have not made complete bibliographical citations, as I understand that the readers are specialists in the historians' craft.

Proteinograma do soro lácteo de ovelhas da raça santa inês em diferentes fases de lactação

This study aimed to evaluate the influence of lactation phases on the proteinogram of whey protein in Santa Inês ewes. Ewes were accompanied in a semi-intensive system using the same sanitary and nutritional management evaluated at 15, 30, 60 and 90 days postpartum (end of weaning and lactation). Clinical examination of the mammary gland was carried out through and bacteriological culture. The screening of the material resulted in 44 milk samples of healthy glands concurrent negative by CMT and bacteriological culture exam. For obtaining the whey protein renin solution was used. The whey was fractionated into aliquots and kept in the -80C freezer to later separation of protein fractions. For determination of total protein of whey protein was employed the biuret, observing the linearity of the test. Separation of protein fractions was performed, using polyacrylamide gel containing sodium dodecyl sulfate (SDS-PAGE). Eigth protein were observed including lactoferrin, serum albumin, IgA, IgG (heavy chain IgG (IgG CP), light chain IgG (IgG CL), ß-lactoglobulin, a-lactalbumin and proteins identified as PM 15000 and PM 29000. No significant difference was observed at different stages of lactation in the following protein: IgA (P>0.3895), lactoferrin (P>0.1611), PM 29000 (P>0.4879), α-lactalbumin (P>0.0799) and PM15000 (P>0.4494). In total protein (P<0.0022), albumin protein (P<0.0377) and IgG (P<0.0354) it was observed a significant variation in the first moments of observations, in the ß-lactoglobulin protein (P<0.0005) there was significant variation with reduction of 15 to 30 days postpartum with progressive elevation until the last stage of lactation (90 days postpartum). The SDS-PAGE technique allowed the quantification of eigth whey proteins in health ewes. The protein fractions identified reflect the profile of whey to ovine species, with influence of stages of lactation in albumin, IgG and ß-lactoglobulin.
