Avaliação dos desenvolvimento da caltura da soja (Glycine max (L.) Merrill) sob diferentes sistemas de preparo

Atualmente na agricultura, a soja ocupa lugar de destaque garantido pela alta produtividade e excelente rentabilidade no mercado nacional, principalmente na exportação de grãos. Sabe-se que para uma boa produtividade é necessário um bom planejamento, além de técnicas de preparo do solo adequadas a cada região do País. Este trabalho, desenvolvido na Universidade Estadual Paulista, Faculdade de Ciências Agrárias e Veterinárias, Campus de Jaboticabal, SP, teve por objetivo, analisar o efeito de diferentes sistemas de preparo no solo e na cultura da soja (Glycine max (L.) Merrill) em Latossolo Vermelho Eutroférrico. Os tratamentos foram 3 preparos convencionais (arado de discos + duas passadas de grade leve, arado de aivecas + duas passadas de grade leve, grade pesada + grade leve), 2 preparos reduzidos (escarificador com rolo destorroador + grade leve, escarificador com rolo destorroador) e semeadura direta, resultando em 6 tratamentos com 4 repetições, totalizando 24 observações. O teor de água no solo não difere entre tratamentos. Na camada superficial (0-5 cm) a semeadura direta apresenta maior resistência à penetração em relação ao arado de aivecas com duas gradagens leves e escarificador com uma gradagem leve. As características agronômicas da cultura da soja não são influenciadas pelos tratamentos estudados.

Digestibilidade e ganhos em peso de ovinos alimentados com diferentes fontes de volumosos e recebendo somatotropina recombinante bovina (rBST)

O objetivo deste trabalho foi avaliar os efeitos da aplicação de 20 mg de somatotropina recombinante bovina (rBST) de liberação lenta, em períodos de 14 e 28 dias, sobre a ingestão de matéria seca, os coeficientes de digestibilidade de matéria seca (MS), fibra em detergente ácido (FDA), proteína bruta (PB) e energia bruta (EB), o balanço de nitrogênio e o ganho de peso diário, em rações à base de silagem de milho, cana-de-açúcar ou bagaço hidrolisado e concentrado. Foi usado um total de 24 borregos mestiços, não-castrados, com média de 4 a 5 meses de idade e 22 ± 2 kg de PV. Não houve efeito da rBST na ingestão de matéria seca, nas digestibilidades de PB e FDA, no balanço de nitrogênio e no ganho de peso diário dos borregos. A digestibilidade da energia bruta foi influenciada pela aplicação de rBST, quando os diferentes volumosos ou períodos pós-aplicação hormonal foram considerados, porém, somente foi observado efeito da ação hormonal sobre a digestibilidade de MS nas dietas à base de silagem de milho.

O currículo e as práticas pedagógicas na EJA: concepções e crenças dos professores da escola municipal Francisca Leonísia Cruz

The present investigation deals with the Curriculum and Pedagogical Practices of Young and Adults, EJA, and articulates with the conceptions and beliefs of teachers sitting. The empirical scope of this investigation consisted in the Municipal School Francisca Leonísia, located in the Agrarian Reform Settlement Serra Nova, city of Florânia/RN. Seeks to analyze the relationship between the Curriculum and Educational Practices of Young and Adult EJA - conceptions beliefs of these teachers. This work is based on qualitative research, interpretative character reflective and makes use of documentary analysis, structured interviews and reflective sessions as methodological procedures which ensure the achievement of our goals in research. These procedures allowed us to enter the practice setting and curriculum for teachers to understand how they think, prepare and practice of adult education in school curriculum research field. The documentary analysis provided the rethinking of the curriculum selected references, Political Pedagogical Project and Proposed Course of EJA, from a critical reading of concepts and conceptions given in these references, with a view to construction and reconstruction of concepts that reclaim the identity of young people and adult field, inserted in the Rural Workers Movement landless/MST. As reflective sessions were constituted in spaces of collective training and allowed the group to selfreflection e collective reflection about the ideas and beliefs that permeate the curriculum and guide their practices education in adult education. In these areas of training are also discussed current problems of adult education, the construction of an educational project of the adult education field to, warranties of learning and cultural identity of the adult education field and placed in the context of the MST. Under this view, it is concluded that the conceptions and beliefs of teachers seated directly relate to the curriculum designed, developed and practiced in adult education, as well as the educational practices that permeate the curriculum. This relation is in the midst of adversities of Rural Education, inserted in the Movement of Landless Rural Workers-MST, and requires the commitment of teachers to the necessary changes to an education are critical and emancipatory

Posição da semente na semeadura e tipo de substrato sobre a emergência e crescimento de plântulas de Schizolobium parahyba (Vell.) S.F. Blake

Rapid and uniform germination of seeds followed by prompt emergence are highly desirable characteristics for the production of seedlings. The aim of this study was to identify sowing positions and types of substrate most likely to the seed germination process and growth of seedlings of Schizolobium parahyba (Vell.) S.F. Blake. To germinate the seeds, they were placed in the following positions in relation to the bottom of the furrow in the substrate: hilum uppermost, hilum at the bottom, supported on one side, seed on edge with its sides parallel to the walls of the bag. Three substrates were used: commercial plantmax substrate (control), pine sawdust and sand. The substrates were fully randomized in a 4 x 3 factorial design (four seed positions and three substrates), with four replications of 20 seeds. The parameters evaluated were: the percentage of emergence, the after emergence seedling deaths, the first-count test, the emergence speed index, and the seedling aerial part length. It was concluded that all the seed positions in pine sawdust sowing offer the more favorable conditions for the germination process and seedling growth of Schizolobium parahyba.

Relações interpessoais no ambiente de trabalho da equipe de enfermagem: uma ação comunicativa

The current study strives to address the interpersonal relationships of the nursing team from the perspective of the communicative action, by contributing to the health work process. It aims to analyze the interpersonal relationships of the nursing team in its work environment. This is a descriptive study with a qualitative approach. Data collection wal held from interviews, guided by a script with open questions. The study was conducted at a state hospital in the city of Natal/RN/Brazil. The research subjects were the workers of the nursing team, including nurses, nursing technicians and nursing assistants, totaling 16 subjects. The capture of information was performed in April 2012. The project was approved by the Ethics Research Committee, under CEP/UFRN protocol n. º 262/11 and Certificate of Presentation for Ethical Consideration n. º 0289.0.051.000-11. The analysis was performed from the categories that emerged from the research through a dialogue with the authors studied in the theoretical framework of the Theory of communicative action , by Jürgen Habermas, as well as The changing in the world of work, by Ricardo Antunes, and Characterization of the team , by Marina Peduzzi. The outocomes point out that the interpersonal relationship of the nursing team is very troubled, with no interaction among the individuals involved in this process, among themselves and with other health professionals. We have developed a particular concept about team, which is comprised of three essential elements: multiplicity of individuals, common objective and heterogeneity. In the studied environment, it was realized the existence of grouping teams. The interpersonal relationship of the nursing can be a facilitator or an obstacle in the workplace in such a way that causes positive or negative consequences, both to the health workers, and to the sicks. In this context, the interviewees have intensified their viewpoints with regard to the weaknesses that permeate the nursing relationship, by pointing them more frequently than the strengths. The work conditions have signaled a failing situation, which is evidenced by the constant improvisation process before the lack of human and material resources, low wages, deficit in recognizing the nursing worker, and physical and emotional wear, by creating a professional exhaustion. The devaluation of the worker also became a strong factor for this study, because it was characterized a reason of job dissatisfaction, due to the lack of valuation policies, which should be prepared by the institution or, even, they are unknown by the worker itself. The worker participation in the design of these policies has emerged as a relevant factor. The poor work conditions lead the worker to a process of professional demotivation and dissatisfaction, by causing the feeling of devaluation within its work environment. Hence, it was found in this research that the lack of communication leads to situations of inadequate interpersonal relationships, which are creators of an unsuitable environment for the performance of the nursing team

Classificação de imagens de ambientes coralinos: uma abordagem empregando uma combinação de classificadores e máquina de vetor de suporte

The use of the maps obtained from remote sensing orbital images submitted to digital processing became fundamental to optimize conservation and monitoring actions of the coral reefs. However, the accuracy reached in the mapping of submerged areas is limited by variation of the water column that degrades the signal received by the orbital sensor and introduces errors in the final result of the classification. The limited capacity of the traditional methods based on conventional statistical techniques to solve the problems related to the inter-classes took the search of alternative strategies in the area of the Computational Intelligence. In this work an ensemble classifiers was built based on the combination of Support Vector Machines and Minimum Distance Classifier with the objective of classifying remotely sensed images of coral reefs ecosystem. The system is composed by three stages, through which the progressive refinement of the classification process happens. The patterns that received an ambiguous classification in a certain stage of the process were revalued in the subsequent stage. The prediction non ambiguous for all the data happened through the reduction or elimination of the false positive. The images were classified into five bottom-types: deep water; under-water corals; inter-tidal corals; algal and sandy bottom. The highest overall accuracy (89%) was obtained from SVM with polynomial kernel. The accuracy of the classified image was compared through the use of error matrix to the results obtained by the application of other classification methods based on a single classifier (neural network and the k-means algorithm). In the final, the comparison of results achieved demonstrated the potential of the ensemble classifiers as a tool of classification of images from submerged areas subject to the noise caused by atmospheric effects and the water column

O masculino em revista: mídia, discurso e modos de subjetivação afetivos-sexuais

This dissertation has the thematic of the sexual affection of the masculine subjectivity within texts of Universo Masculino and Men‟s Health magazines as object of analysis. The central objective was to describe and interpret the theme on the masculine subjectivity in discourses about the affection of sexuality materialized in discourse practices in those magazines. The main point of the research matters how the discourse structures of texts in those magazines make it possible to comprehend the meanings produced about the masculinity nowadays. On the perspective of the thematic trajectory what consists the main aspect that concerns the leading of corpus in the research under the French discourse analysis, we have searched, in reports of those magazines, an arch-genealogy of masculinity, from a specific sexual-affection disposable of our mediate culture. The analytic trajectory enables us to conclude that the thematic trajectory about the sexual affection of the masculine subjectivity produces a semantic way that confirms hegemony and hetero-normative ideals, rather than what proposes new performances on the masculine subjectivity experiences. In its real effects, such mediate discourse practice pursues to link certain sexual affection knowledge to the male individual‟s lifestyle today, from the thematic choices, enunciation modalities and discourse strategies which are specific to the masculine media

Temperatura do solo em função do preparo do solo e do manejo da cobertura de inverno

Com o objetivo de avaliar o efeito do preparo do solo e do manejo da cobertura de inverno (consórcio aveia-preta + nabo forrageiro) sobre a temperatura do solo, realizou-se um experimento em um Nitossolo em Botucatu-SP no outono/inverno de 2000. Utilizou-se um delineamento em blocos casualizados em esquema fatorial 3 x 3 (três preparos e três manejos). O preparo do solo constou de: preparo convencional, preparo conservacionista com escarificação e plantio direto, e o manejo da cobertura: consórcio dessecado, rolado e triturado. Foram avaliados a temperatura do solo (termopares) a 5 cm de profundidade, de hora em hora, aos 7, 14, 30, 45 e 60 dias após a emergência das plantas do consórcio; o teor de água do solo na profundidade de 10 cm, nas mesmas épocas; e a cobertura do solo (massa seca e índice de cobertura), imediatamente após aplicação dos tratamentos. O sistema plantio direto apresentou temperaturas do solo menores que as do preparo convencional, até o 14º dia após emergência (DAE) das plantas. A partir do 30° DAE das plantas, a temperatura não foi mais influenciada pelos tratamentos, devido à cobertura do consórcio e ocorrência de boa disponibilidade de água no solo. Os manejos da cobertura com rolo-faca, triturador e herbicida não influenciaram a temperatura do solo. A temperatura do solo não interferiu no crescimento e desenvolvimento das culturas de cobertura.

Alterações nas características físicas do maracujá-doce submetido à imersão em solução de cloreto de cálcio

Este trabalho teve por objetivo estudar o efeito da imersão em solução de cloreto de cálcio nas características físicas do maracujá-doce (Passiflora alata Dryander), durante seu armazenamento. Os frutos, colhidos no estádio pré-climatérico, após desinfecção com o fungicida thiabendazol (1g/l) foram imersos, por duas horas, nas seguintes concentrações de cloreto de cálcio: testemunha (0% de CaCl2), 1% de CaCl2, 2% de CaCl2, 3% de CaCl2 e 4% de CaCl2. Após os tratamentos, todos os frutos foram armazenados sob condições de refrigeração (9°C e 85-90% UR), durante 30 dias. Os frutos foram avaliados a cada 6 dias quanto à perda de massa fresca, coloração e rendimento de polpa. Ao final do período estudado pode-se verificar que a concentração de 1% de CaCl2 foi a que melhor retardou a evolução da cor da casca. Não ocorreu influência das doses aplicadas na perda de massa fresca e no rendimento de polpa dos frutos. A concentração de 4% de CaCl2 foi excessiva para o maracujá-doce, pois contribuiu para a perda de massa fresca e para o amadurecimento dos frutos.

Reguladores vegetais no desenvolvimento e produtividade da cana-de-açúcar

O objetivo deste trabalho foi avaliar o desenvolvimento e a produtividade de colmos de cana-de-açúcar, resultantes da aplicação de reguladores vegetais no iníco da safra. Ostratamentos consistiram na aplicação de três reguladores vegetais inibidores de crescimento - sulfometuron metil, glifosato e compostos de radicais carboxílicos orgânicos + glifosato - e na maturação natural como testemunha, em delineamento experimental em blocos ao acaso, com cinco repetições. Os maturadores retardam o processo de crescimento em altura das plantas, sem afetar o número e o diâmetro de colmos na colheita, e influenciam de forma e intensidade distintas a ocorrência do florescimento e chochamento. O glifosato proporciona elevados índices de brotação lateral e prejudica a rebrota da soqueira. Os maturadores induzem o aumento do teor de açúcares redutores totais, o que contribui para a melhoria da qualidade tecnológica da cana-de-açúcar.

Diagnóstco geoambiental e avaliação de uso e ocupação do campo de dunas da zona especial de interesse turístco II (ZET-II) Natal/RN

The accelerated pressure of use and occupation of Rio Grande do Norte coastline in the last two decades presented the tourism as its main vector, having as a consequence a strong, articulated and growing real estate speculation of this area. In the Natal County there is a Zona Especial de Interesse Turistico II (Special Zone of Tourism Interest II) (ZET-II), consisted of urban beaches with approximately 8.5 km that is an important seashore of the city. The purpose of this research was identification, characterization and assessment of the process of use and occupation of dunes fields emphasizing the role of ZET-II, whereas the specific goals was the analysis of weather, geology and geomorphology, characterization of use and occupation of soil, and elaboration of an environmental diagnosis with identification and description of its mains consequences. The result of this work was the delineation of geologic-geomorphological map of the area with identification of principals units, determining its use and occupation, the measurement of the area already occupied by equipments, besides the description of the environmental impacts on dune fields: devastation, coastline erosion, ocean pollution by sewer and pluvial waters, contamination of groundwater, distribution inadequate of solid residues, landscape degradation, and occupation of seashore through the privatization of public areas. Concluding that the degrading changes occurred in this areas are resulting from the nature of use and urban seashore regulations, which have been diminishing the natural aspect, altering the landscape definitely, compromising the quality of hydro resources and altering its use, privatizing the areas between tides, complicating the population access and obstructing the scenery visualization of dunes and ocean. There is an urgent necessity of improvement of public politics in order to improve the strategies and organization of use and occupation of space urban-coastline
