Avanços metodológicos na avaliação da qualidade da forragem conservada

A avaliação correta do valor nutricional da forragem passa obrigatoriamente por emprego de metodologias adequadas. A qualidade da forragem depende dos produtos da fermentação, no caso da silagem, ou da magnitude das perdas de compostos solúveis e atuação de microrganismos no caso do feno. A abordagem do tema: Avanços metodológicos na avaliação da qualidade da forragem conservada, na 44ª Reunião Anual da Sociedade Brasileira de Zootecnia, tem como objetivo destacar as principais metodologias empregadas na avaliação específica de forragens conservadas, adicionais às avaliações tradicionais de composição químico-bromatológica desses volumosos, e colocar em discussão a necessidade de padronização de procedimentos analíticos. Assim, a revisão prioriza a descrição e sistematização de métodos físicos e químicos importantes para serem implementados na avaliação de forragens conservadas, na tentativa de homogeneizar tais procedimentos. Os recursos metodológicos disponíveis atualmente permitem não somente quantificar, mas também qualificar perdas ocorridas no processo de conservação, exposição aeróbia e oferta dos volumosos aos animais. Esse fato sugere que a adoção de estratégias de manejo dessas forragens deverá, preferencialmente, ser acompanhada de avaliação de perdas integradas no processo.

RELATIVISTIC 3-PARTICLE DYNAMICAL EQUATIONS .2. APPLICATION TO THE TRINUCLEON SYSTEM

We calculate the contribution of relativistic dynamics on the neutron-deutron scattering length and triton binding energy employing five sets trinucleon potential models and four types of three-dimensional relativistic three-body equations suggested in the preceding paper. The relativistic correction to binding energy may vary a lot and even change sign depending on the relativistic formulation employed. The deviations of these observables from those obtained in nonrelativistic models follow the general universal trend of deviations introduced by off- and on-shell variations of two- and three-nucleon potentials in a nonrelativistic model calculation. Consequently, it will be difficult to separate unambiguously the effect of off- and on-shell variations of two- and three-nucleon potentials on low-energy three-nucleon observables from the effect of relativistic dynamics.

Serologic profile in hepatitis B virus and hepatitis C virus in a Brazilian liver transplant waiting list

Chronic viral hepatitis is currently the most common indication for liver transplantation (OLT). Knowing the serological profile of patients on the liver transplant waiting list (LTWL) is essential to manage prophylactic and therapeutic strategies pre- and post-OLT. The aim of this study was to determine the hepatitis B virus (HBV) and hepatitis C virus (HCV) serological profile on the LTWL.Methods. Serological data were collected from 44 candidates included on, the LTWL from May 2003 to November 2004. HBV and HCV serological profiles were performed by microenzyme immunoassay.Results. Twenty-eight patients (66.7%) lacked H13V serological markers. Anti-HBs was detected in 9.5% and was positive for HBsAg, anti-HBc, IgM anti-HBc, or HbeAg in 4.8% of patients, probably related to reactivation of chronic infection. In 7.1% of patients, the markers demonstrated serological cure of infection. In HCV patients, 41.5% were positive. There was H13V and HCV co-infection in 12.2% of patients.Conclusion. HBV infection in 21.4% of the patients corroborates the need to use more efficient protocols for prophylactic and therapeutic management pre- and post-OLT. The high prevalence of HCV infection reinforces the need to follow adequate protocols to avoid related complications and guarantee rational and universal use of more efficient drugs.

Intellectuals and Japanese Buddhism in Brazil

This study concentrates on the discovery of Japanese Buddhism by Brazilian intellectuals as a group of spiritual practices and as a body of spiritual wisdom. The study has been realized through readings and meetings with Japanese Buddhist monks and/or Japanese immigrants. These intellectuals defend a religious experience based on a universal notion of representations of Japanese Buddhism, which provides them with a non-dualistic philosophical perspective and a unique psychological experience. Through innovative spiritual experiences these intellectuals have broken the tension created within the dispute between secularized science and the Catholic hegemony, both predominant in the intellectual panorama.

Identificacao e mapeamento de areas de maior eficiencia fotossintetica para a cana-de-acucar

The objective was the study of better areas for sugar cane exploitation, using variables related to the classes and exposition of slopes, edaphic and climatic variables. Data were analysed with the aid of a Geographic Information System supported by 8 bit microcomputer, and maps of North exposition, photosynthetically the most efficient, were produced for different gradients of slope. These maps combined with traditional maps can be a very helpful tool to planners. -from English summary

A note on non-degenerate umbilics and the path formulation for bifurcation problems

Path formulation can be used to classify and structure efficiently multiparameter bifurcation problems around fundamental singularities: the cores. The non-degenerate umbilic singularities are the generic cores for four situations in corank 2: the general or gradient problems and the ℤ 2-equivariant (general or gradient) problems. Those categories determine an interesting 'Russian doll' type of structure in the universal unfoldings of the umbilic singularities. One advantage of our approach is that we can handle one, two or more parameters using the same framework (even considering some special parameter structure, for instance, some internal hierarchy). We classify the generic bifurcations that occur in those cases with one or two parameters.

Subjetividade sujeitada e prática psicológica: Perspectivas do sujeito da ação

Research problematizes readings on the so-called subject or agent of action as associated to group constitution and analyzes the implications of such interpretations in psychological practice and in the constitution of subjectivity. The article is based on interdisciplinary readings and on different areas of knowledge so that identity references overlying the modern subject of action may be problematized. Critical emphasis is foregrounded on the classical logic, identity and subjected subjectivity as a-temporal and universal factors of action in the real world. The problematization of subjectivity's construction and its relationships with modes of knowledge will contribute towards the establishment of critical theoretic and strategic interventions.
