1. Desenvolvimento de um modelo termohidrodinâmico para análise em mancais segmentados / Development of a thermohydrodynamic model for analysis in tilting pad journal bearings
Este trabalho tem por objetivo analisar o comportamento termohidrodinâmico de mancais hidrodinâmicos segmentados e avaliar a influência da temperatura nas características dinâmicas (coeficiente equivalente de rigidez e de amortecimento) desses mancais. Por esse motivo, foi desenvolvido um modelo termohidrodinâmico para análise em mancais segmentados,

2. Influence of surface roughness and the use of new types of fiber in bearing pads of cement-based material for precast concrete connections / Influência da rugosidade superficial e o uso de novos tipos de fibras em almofadas de argamassa para ligações de concreto pré-moldado
This paper presents the study of a mortar modified to be used as a bearing pad connections between precast concrete elements. This mortar is composed of cement and sand, with the addition of styrene-butadiene latex (SB), lightweight aggregate (vermiculite) and short fibers (polypropylene, glass and PVA). Previous research showed that this composite presents

3. Almofada de apoio de compósito de cimento para ligações em concreto pré-moldado / Bearing pad of cement composite for connections in precast concrete
This research presents a study of a mortar modified to use as bearing pad between precast concrete elements. The mortar used in this research is achieved by the introduction of styrene-butadiene latex (SB) and polypropylene fibers into a cement mortar and sand, modifying their mechanical properties, as increase of the potential deformation by decrease of the

4. Identificação das propriedades dinamicas de mancais segmentados hibridos : teoria e experimento
The stability of rotating machines is strongly related to the type of coupling between the rotating and stationary parts. The bearings are one of the most important stationary part for defining the operational stability range of such a kind of machines. The goal of this research work is to study a new type of hydrid lubrication, where the oil is electro nica

5. Polyribosomes from Peas: An Improved Method for Their Isolation in the Absence of Ribonuclease Inhibitors 1
Profiles of polyribosomes were obtained from etiolated stem segments of Pisum sativum L. var. Alaska isolated in various buffers. Tissue homogenized in a medium containing 0.2 m tris-HCl, pH 8.5, 0.2 m sucrose, 30 mm MgCl2, and 60 mm KCl yielded polyribosomes exhibiting far less degradation than tissue homogenized in conventional media containing tris-HCl at

6. Aggregation Substance Promotes Adherence, Phagocytosis, and Intracellular Survival of Enterococcus faecalis within Human Macrophages and Suppresses Respiratory Burst
The aggregation substance (AS) of Enterococcus faecalis, encoded on sex pheromone plasmids, is a surface-bound glycoprotein that mediates aggregation between bacteria thereby facilitating plasmid transfer. Sequencing of the pAD1-encoded Asa1 revealed that this surface protein contains two RGD motifs which are known to ligate integrins. Therefore, we investig
