1. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

2. Unitarity in Noncommutative Field Theories / Unitariedade em teorias não comutativas
Este trabalho é dedicado ao estudo da unitariedade em teoria de campos não comuta- tiva. Inicialmente, são apresentadas as ferramentas básicas para abordar o problema da unitariedade em teorias não comutativas, incluindo as regras de corte e uma introdução à não comutatividade. Em seguida, foi feita a análise do modelo Á3 não comutativo. Empregan

3. PRENATAL CARE IN THE STATE OF MARANHÃO / ASSISTÊNCIA PRÉ-NATAL NO ESTADO DO MARANHÃO
The prenatal assitance enlarges a set of actions which aim to promote the pregnant womens health and the new-borns and also the set of adequated actions to the prevention, the diagnosis and the clinic handing of obstetrical problems which can occvr or of illnesses previovsly ixisting and that can affect the mothers and their children. It was done a descripti

4. Microbial load of reusables trocars after gynecology laparoscopy / Carga microbiana de trocartes reprocessaveis apos laparoscopias ginecologicas
The transmission of hospital infections is related to survival of microorganisms on environmental surfaces and surgical instruments. In recent years, Brazil has been facing a scenario scattered on the validation of cleaning and sterilizing surgical instruments used in minimally invasive procedures performed primarily for video. For implantation of effective

5. Desenvolvimento, globalização e politicas sociais : um exame das determinações contextuais dos projetos de reforma da educação e da saude brasileiras da ultima decada
Education and health care policies are products from complex relationships between the economic-social and political-ideological dimensions from a certain historical context of capitalism development. Having this relationship as presupposed and the particular characteristics of the Brazilian capitalist development process as a reference, we analyzed, in this

6. IDENTIFICACIÓN DE SISTEMAS DE EXTRUCTURAS MECÁNICAS Y APLICACIONES / IDENTIFICATION OF MECHANICAL SYSTEMS WITH APPLICATIONS / IDENTIFICAÇÃO DE SISTEMAS DE ESTRUTURAS MECÂNICAS E APLICAÇÕES
The aims of this work are three: First, to make a brief review of linear system and estimation theory used in mechanical structure problems. Second, to study an algorithm called ERA (Eigensystem Realization Algorithm) that provides a minimal realization using the input (forces, moments, impulses) and output signals (accelerations). Third, to develop some num

7. Recursions for statistical multiple alignment
Algorithms are presented that allow the calculation of the probability of a set of sequences related by a binary tree that have evolved according to the Thorne–Kishino–Felsenstein model for a fixed set of parameters. The algorithms are based on a Markov chain generating sequences and their alignment at nodes in a tree. Depending on whether the complete r

8. The ethical analysis of risk in intensive care unit research
Research in the intensive care unit (ICU) is commonly thought to pose 'serious risk' to study participants. This perception may be at the root of a variety of impediments to the conduct of clinical trials in the ICU setting. Component analysis offers a promising approach to the ethical analysis of ICU research. Because clinical trials commonly involve a mixt

9. Targeting a Polyepitope Protein Incorporating Multiple Class II-Restricted Viral Epitopes to the Secretory/Endocytic Pathway Facilitates Immune Recognition by CD4+ Cytotoxic T Lymphocytes: a Novel Approach to Vaccine Design
The role of CD4+ and CD8+ cells in the generation of an effective immune response against viral infections is well established. Moreover, there is an increasing realization that subunit vaccines which include both CD4+- and CD8+-T-cell epitopes are highly effective in controlling viral infections, as opposed to those which are designed to activate a CD8+- or

10. Key Role for DsbA in Cell-to-Cell Spread of Shigella flexneri, Permitting Secretion of Ipa Proteins into Interepithelial Protrusions
DsbA, a disulfide bond catalyst, is necessary for realization of the pathogenic potential of Shigella flexneri. Sh42, a mutant strain differing from wild-type M90TS solely because it expresses nonfunctional DsbA33G (substitution for 33C at the active site), secreted less IpaB and IpaC than M90TS in response to various stimuli in vitro. A kinetic study demons

11. Plasmodium gallinaceum preferentially invades vesicular ATPase-expressing cells in Aedes aegypti midgut
Penetration of the mosquito midgut epithelium is obligatory for the further development of Plasmodium parasites. Therefore, blocking the parasite from invading the midgut wall disrupts the transmission of malaria. Despite such a pivotal role in malaria transmission, the cellular and molecular interactions that occur during the invasion are not understood. He
