Abstract: phosphorus is an important mineral nutrient for vegetables. this work was conducted at universidade federal da paraíba, in areia, brazil, from december/2001 to july/2002, aiming to evaluate the effect of levels of p2o5 on the yield of lima bean, cv. "orelha de vó". the experimental design was a randomized block with five treatments (0; 100; 200; 300; 400 and 500 kg ha-1 of p2 o5), and four replications. each plot consisted of 40 plants spaced 1.0 m between rows and 0.50 m between plants in each row. the estimated maximum yield of green and dry beans (5.2 and 2.7 t ha-1, respectively) corresponded, to the dosages of 309 and 302 kg ha-1 of p2o5. the levels 291 kg ha-1 and 281 kg ha-1 of p2o5 provided, respectively, the greater economic return for the yield of green (4.1 t ha-1) and dry (1.8 t ha-1) beans. the most economic levels included more than 80% of those dosages responsible for the maximum yields and indicated the economic viability of phosphorus utilization on lima bean crop. the p2o5 levels which promoted the maximum yield and the maximum economic return for green and dry beans yield were respectively, with 57.1; 56.3; 55.0 and 53.8 mg dm-3 of available p for the extractor of melich 1. the lima bean response to the phosphorus fertilization in soils with similar fertility used in the present study, for green and dry beans yield, will be reduced at levels of available p superior to 55.0 and 53.8 mg dm-3. the average concentration of p in the leaves of lima bean, 120 days after sowing, in function of levels of p2o5 was of 3.4 g kg-1. for the soil of this study the application of 291 and 281 kg ha-1 of p2o5 is more recommended to establish the lima bean respectively, for green and dry beans yield.

Abstract: The appropriate nutrient supply via fertilization is essential for an adequate plant growth and development. The objective of this study was to evaluate the structural characteristics and chlorophyll index of Marandu and Xaraes grasses fertilized with wood ash. The experiment was conducted in a greenhouse; the experimental design was entirely randomized, with 12 treatments and six replications arranged in a 2 × 6 factorial scheme: two forage grasses (Marandu and Xaraes) and six wood ash doses (0; 3; 6; 9; 12; and 15 g·dm-3). Each plot was composed of pots with 7 dm3 soil and five plants. Soil moisture was maintained by the gravimetric method at 60% of the maximum soil water retention capacity. Three harvests of the plant aerial part were performed at 30-day intervals. The evaluated characteristics were plant height, leaf number, tiller number, and chlorophyll index. Results were submitted to the variance analysis by F test and, after verification of the significant effects on Marandu and Xaraes characteristics, were also submitted to Tukey test; the wood ash doses were evaluated according to the regression analysis at 5% probability. Wood ash doses ranging from 10.15 to 15 g·dm-3 resulted in quadratic responses of plant height, leaf number, and tiller number for both Marandu and Xaraes grasses. The highest values of chlorophyll index derived from wood ash doses of 9.44 and 10.92 g·dm-3, with increments greater than 50%, 25%, and 9% at the first, second, and third harvests, respectively. The wood ash, when used as a fertilizer, improves structural characteristics and increases chlorophyll indices of Marandu and Xaraes grasses cultivated in Cerrado Rhodic Hapludox.

Abstract: this paper focuses on adolescents who had a previous experience of school failure. its main purpose was to verify whether children with academic complains but judged by their mother as interpersonally competent would show better achievement and adjustment later, when compared with others of the same clinical population. forty eight adolescents aged 10 and 15 years participated. on the basis of interpersonal skills indices obtained from the clinic archive records, three groups were formed: competent; vulnerable; reference. at a follow-up one to two years after clinical discharge, children were assessed with the academic achievement test, the piers-harris children's self-concept scale, the self-efficacy schedule, a follow-up interview and the cbcl. in group comparisons, the adolescents that were classified as interpersonally competent in childhood had better academic, self-perception and behavior results. these results suggest that, in face of school adversities, children with better interpersonal resources have more favorable developmental trajectories.

Barbarói , 2011,
Abstract: Este trabalho busca compreender as rela es conceituais entre a concep o de produ o de subjetividade e de constru o do sujeito. Discorre sobre alguns conceitos que entrela am as no es psicanalíticas e sociais, apontando para diferentes modos de pensar subjetividade e sujeito, ressaltando as possibilidades que abarquem concep es contraditórias, complementares e, até mesmo coincidentes. Tentamos, ao longo dessa reflex o, apresentar pontos de media o teóricos que possibilitem pensar uma concep o de sujeitocontemporaneo que seja, ao mesmo tempo, Estrutura e Acontecimento. Abstract This paper aims to understand the conceptual relations between the subjectivity production concept and subject construction. It addresses some concepts that interweave the social and psychoanalytic notions, pointing to different ways of thinking subjectivity and subject, underscoring the possibilities that encompasses contradictory, complementary concepts and, even coinciding. While considering this, we attempted to present theoretical mediation points that make it possible to come up with a contemporary subject conception, which, at the same time, is Structure and Event.
O racismo como subproduto de uma sociedade de classes
José Bezerra da Silva,Maria Edna Bertoldo
Revista Espa?o Acadêmico , 2010,
Abstract: O racismo é descrito no texto como uma forma terrível de apropria o do trabalho humano. Assim, subscreve-se como um subproduto em que a classe dominante explora o trabalhador e dentre estes seleciona a partir da cor e de outros tra os morfológicos uma imensa parcela da popula o para exercer certos trabalhos tidos como trabalhos inferiores. Em todo caso, o texto traz muitas informa es históricas sobre o racismo, visualiando seu início nos tempos modernos e que só tem sentido na sociabilidade do capital. Por isso sugere que ao se combater o racismo o fa a também à divis o da sociedade em classes, objetivando, desse modo, implementar a emancipa o humana.

Abstract: The use of cover plants promotes the recycling of nutrients and the increase in organic mass, and minimizes the effects of erosion. The objective was to evaluate the effect of bulk density in the development of jack bean (Canavalia ensiformis) in Cerrado Oxisol. The experiment was conducted in a greenhouse at the Federal University of Mato Grosso, Rondonópolis-MT, in the period from June to September 2013. Oxisol was used from a Cerrado reserve area, collected at 0 - 0.20 m depth. The experimental design was completely randomized, corresponding to bulk density levels (1.0, 1.2, 1.4, 1.6 and 1.8 Mg·m-3), and five replications. The experimental plot consisted of three PVC rings (polyvinyl chloride) with 150 mm internal diameter, 300 mm total height, where the upper and lower rings of pots were filled with 1.0 Mg·m-3 density soil and intermediaries according to bulk density treatments. The results were submitted to variance analysis and, when significant, to regression analysis, both with a 5% probability, using SISVAR software. At 60 days after germination, number of leaves, stem diameter, plant height, dry mass of leaves, stem dry mass, dry mass of roots, dry mass of nodules, number of nodules and chlorophyll index (SPAD index) were evaluated. The increase in bulk density negatively influences the development of jack bean, showing little efficiency as a decompacting plant in Cerrado Oxisol.
