Determinação da distribuição de um nível de turbidito na formação Macaé no campo de Namorado através de uso de atributos sísmicos

This study was developed on the basis of petrophysics characterization, 3D seismic interpretation, and rock-wire-log integration. The results were integrated with amplitude attribute through cross plot (rock attribute x amplitude value). 3D seismic data also allowed inteipreting the top of Lagoa Feia, Macaé, and Carapebus formations, and Outeiro Member. The analyses of the maps of structures and attributes, integrated with wire-log data, suggest that Namorado turbidite level is candidate to be mapped with stratigraphic attributes like AverageTroughAmplitude, RMS velocity and Total AbsoluteAmplitude. Lagoa Feia Formation attribute maps (Dip-Azimuth and TotalEnergy) allows to interpret a low fault density at the carbonate coquina level in the Namorado field. This level is also considered one at the best seismic reflector and an important reservoir of the Campos Basin.

Efeito residual de calcário, nitrogênio e zinco na produção de matéria seca de Brachiaria decumbens em condições de campo

The balance of liming and fertilization practice with nitrogen and zinc could affect the production of the pasture. Thus, the present work has as objective to evaluate the residual effect of the application of calcareous rock, nitrogen, and zinc on the dry matter production of Brachiaria decumbens, during three cuts. For this, an experiment was installed in Selvíria, Brazil, on a distrofic red Latosol, from october 1997 to may 1998. The experimental design was randomized blocks, in a factorial project 3×3×2, with four repetitions. The treatments were three doses of nitrogen: 0, 50, and 100 kg/ha, three doses of lime: 0, 267, and 556 kg/ha, corresponding to 41, 50, and 60% of the levels of base saturation, respectively, and two doses of zinc 0 and 5 kg/ha, applied in the first year and reapplied in the second year, except for the limestone. Four cuts were done in the grass at 10 cm of height, with intervals of 49 days, to obtain the dry matter production. The limestone application in the first year did not provide to residual effect on the production of Brachiaria decumbens. However, the nitrogen fertilization increased the dry matter production of the grass. The application of zinc in the first year and the reapplication in the second year did not result in a productive response of B. decumbens. © 2009 Instituto Nacional de Investigaciones Agricolas INIA.

Efeito agudo do aquecimento realizado através de exercícios dinâmicos e jogo de futebol em campo reduzido sobre a agilidade em crianças

The aim of this study was to evaluate the effect of warm up performed by dynamic exercises (DYN) and small sided soccer game (SOC) on agility with ball (AB) and agility without ball (AG). Eighteen children of both genders (n=18) performed the AB and AG tests after three conditions: without warm-up (WWU), DYN and SOC. The effects of DYN and SOC warm-ups on AG test was higher than WWU (p<0,05) and it was similar among them (WWU=12,2 ± 1,0, DYN= 11,3 ± 0,7, SOC=11,4 ± 0,6 s), as well as on AB test (WWU=15,0 ± 2,1, DYN= 14,4 ± 2,1, SOC=14,0 ± 1,6 s). Results in both tests were similar by gender, except in AB test performed with DYN warm-up, in girls. SOC is an effective warm-up protocol for agility tests with or without ball and can be used before agility motor tasks in children.

Paradigmas diversos no campo da assistência social e seus estabelecimentos assistenciais típicos

In order to understand what is the situation of entities that serve children and adolescents today, as well as the institutional plot that comprises these institutions, we aimed to formulate a set of paradigmatic possibilities that would allow us to understand the configuration of the dialectical field of various pulses, in which these entities are located. We detected the subjects we associate with counterparts paradigms of Charity, of Human Promotion, of Philanthropy, of assistentialist government patronage, of Social Work as a State Policy, and finally, another set of events that we propose to designate as the paradigm of Citizen Subjects we associate with the ethical perspective of People Education. These paradigmatic possibilities range from the simply various and contrasting ones, including the similar and competing ones, to the dialectically contradictory ones. Its spectrum oscillates between tutelage and citizenship. The characterization of these didactic paradigms can provide us a compass that is required in a highly complex social field, allowing us to understand the variety of ethical effects promoted by these paradigms in the social field.

Estabelecimento de fungos nematófagos aplicados no campo para o controle dos nematoides-chaves dos citros no Brasil

Monitoring the survival of nematophagous fungi is needed to establish periods of reapplication of formulations of nematophagous fungi to control the citrus nematode in the field. We monitored the survival of fungi: Arthrobotrys robusta, A. oligospora, A. musiformis Dactylella leptospora and Monacrosporium eudermatum in plots treated with 1, 2, 4, 6 liters of the formulation of fungi/plant or witness without the application, during the period of nine months with the first assessment six months after application and the other with intervals of three months after the first evaluation. The fungus D. leptospora was found only in the evaluation of 6 months after treatment application, indicated a short survival time in the soil. However, the isolated A. robusta, A. musiformis and A. oligospora were recovered in all evaluations and especially in plots treated with higher doses of the formulation and witness. Monacrosporium eudermatum was recovered in all experimental periods and even in assessing the witness portion of nine months after application. The fact of the presence of species of Arthrobotrys and M. eudermatum in control plots indicates that native species that were already orchard.

A Hermenêutica no Campo Organizacional: Duas possibilidades interpretativistas de pesquisa

The present text has the objective of presenting theoretical considerations regarding two types of strategy of research: phenomenology and ethnography. Based on a hermeneutic approach, the two conceptual propositions are presented, the first being dealt with in the sociological context, and the second presented as an anthropological basis. Their similar uses in an organizational context - as well as their differences - are highligthed according to the theoretical contributions of authors belonging to the qualitative universe of organizational research. The text reveals, by the presentations of reported theoretical assumptions, the relevance of the interpretative perspective for the conduction of research that has the organization as object of study, in the pursuit of the identification of ways of constructing the social reality that is the result of the analysis of meanings and experiences lived by the participants, highlighting the importance of the bond between researcher and the research object The theoretical discussion regarding the two perspectives allows to observe the competence of the phenomenological and ethnographic research practice within the field of organizational studies, showing their methodological possibilities to identify dynamics that relate to the experience of life, favoring the analysis of the human being as a phenomenon of interpretation. © FECAP.
