Relações hídricas em cultivares de beterraba em diferentes níveis de salinidade do solo

The excess of salts in the soil can directly affect the development and yield of the plants, therefore, studies on water relationships of crops in such conditions are necessary to prevent or solve the problem. The study was conducted in a greenhouse at Universidade Estadual Paulista, Department of Agricultural Engineering, Botucatu, Brazil. The statistical design used was randomized blocks with four replications, consisting of five levels of soil salinity (1.0, 3.0, 6.0, 9.0, 12.0 dS m-1), two cultivars of sugar beet (Early Wonder and Itapuã) and two types of management of fertigation, totaling in all 80 plots. Measurements of water content of the leaves, diffuse resistance to water vapor, transpiration, leaf area and the water consumption of crop were determined. There was a decrease according to increasing salinity for the analysed physiological parameters in the Early Wonder variety while for the Itapuã variety a gradual increase was observed up to a salinity of 6 dS m-1. The water consumption by plants showed a reduction with increase of soil salinity for the two varieties.

Relações entre aquisição da percepção auditiva e aprendizagem da ortografia: consoantes soantes em questão

We compared the relationships between acquisition of auditory perception and the acquisition of sonorant consonants spelling in children of the first two grades of elementary school. The comparison was based on a procedure of identifying and writing the same set of words that presented phonological contrasts between them. As to the results, it was found: (1) gradation in the acquisition of subclasses within a larger class; (2) matches and mismatches between the two types of task; (3) increased adjustments in spelling and more mismatches in auditory perception with increasing enrollment. This set of results indicates, therefore, the complexity of the relationships between the acquisition of auditory perception and the acquisition of spelling, since, once contacted, their journey together at the same time promotes links and outcomes between them.

Inter-relações da produtividade de cana soca com a resistência à penetração, umidade e matéria orgânica do solo

The sugarcane crop plays an important role on Brazilian economy,, especially in the aspect related to alternative energy sources. Yield of ratoon cane (2nd cycle) was evaluated in relation to resistance to penetration, gravimetric moisture and organic matter in a Typic Tropustalf, in the municipality of Suzanápolis (SP), 20º28'10'' S and 50º49'20'' W, in the Brazilian cerrado, in 2009. The main purpose was to select, among the attributes surveyed, the one with the highest linear and spatial correlations that explains the variability of sugar cane yield. A geostatistical grid was installed in order to collect data from the soil as well from the plant, with 120 sampling points in an area of 14.53 ha. Organic matter correlated linearly and negatively with penetration resistance, indicating that the soil management practices that aim its increase in the soil profile can improve soil physical conditions, and consequently, the development and yield of sugarcane. Both gravimetric moisture (UG) and content of soil organic matter (OM) correlated directly, linearly (UG2 and MO1) and spatially (UG1 and MO1) with sugarcane yield, proving to be the best attributes, among the evaluated ones, to estimate and increase the sugarcane yield.

Gestão escolar e formação do pedagogo: relações e implicações a partir da análise de projetos político-pedagógicos de universidades públicas

The literature has pointed out the educational deficits of Brazilian public schools, the complexity of school management, and the need for better qualification for the exercise of this function. Considering this perspective, the present research questions: How is school management being contemplated within the initial pedagogical training in the state of Paraná? In this sense, this article aims to survey and analyze how school management in professional training in public universities Educator of Paraná is being contemplated after the publication of the National Curriculum Guidelines for the Education Course (DCNP). The study works with a qualitative approach to carry out, in the one hand, the bibliographic survey and systematization and, on the other hand, the survey, systematization and analysis of some elements in the political-pedagogical projects of different public universities. The data collected in six public universities show a significant oscillation between the workload aimed at the knowledge of School Administration and a variety of covered contents. Such differences may reflect the scope of the National Curriculum Guidelines as well as the present theoretical dispersion regarding the current knowledge on School Administration.

História da educação e literatura: possibilidades de relações

In the last decades of the 20th Century, the History of the Education, as well as that of Mathematical Education have used the background of the New History and Cultural History. It has changed its objects, methods and sources. Despite the diversification of sources, some of them have still not been used systematically in research. This is the situation with regard to fiction texts. According to Lajolo (1997), literature is the radar and mirror of the values, emotions, feelings and point of view of societies. Therefore we can pose questions to literary texts to seek historical narratives. In this paper, parts of the literary texts Novelas Paulistanas and Memórias de um Sargento de Milícias have led us to historical research in secondary sources. We aim to contribute to understanding of the Brazilian Empire's process of school education, in Rio de Janeiro, and of the FirstRepublic's educational process, in São Paulo.

Relações de complementação no português brasileiro: uma perspectiva discursivo-funcional

É apresentado nesse estudo uma investigação sobre os tipos de orações completivas, distribuídas numa hierarquia entre mais ou menos verbal/nominal, tendo como suporte dados reais de conversação. Trata-se de um trabalho sobre a gramática da complementação do português brasileiro, mais especificamente sobre construções gramaticalmente disponíveis, com base em determinados tipos de predicados encaixadores verbais, em relação ao papel que essas construções exercem nas estruturas completivas do português
