Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...

anniversary of the Brazilian Journal of Cardiovascular Surgery (BJCVS). We asked some collaborators of the Journal to express their sentiments about the interaction of them with the publication, and the importance that it represented in their lives. Was not surprise to have many important manifestations of the colleagues, to show historical facts and personal impressions about the challenge tha...

The first paper, by Cavalcanti et al, was selected as the best paper in the SBMIDIA99 conference – Brazilian Multimedia Symposium. It concentrates on an important issue – that of management of sound (MIDI) files. Retrieval of multimedia data is based on textual description and indexing of some file characteristics. This involves two complicated issues – selecting features to describe, in order ...

Tropical endomyocardial fibrosis is a rare entity in the present era. Restrictive cardiomyopathy due to tapioca consumption is very rare, although it has been reported in India, especially in state of Kerala. We report a rare case of restrictive cardiomyopathy secondary to tapioca consumption in a 20-year-old male patient.

The aim of this study was to identify, in bibliographic production, how Brazilian nurses have been discussed "work process" in nursing practice. The bibliographic research was realized in Lilacs, in a period from January of 1993 to December of 2003, and focus the periodics: Acta Paulista de Enfermagem, Nursing (SP), Revista Brasileira de Enfermagem, Revista da Escola de Enfermagem da USP, Revis...

BACKGROUND AND OBJECTIVES Statistical analysis is necessary for adequate evaluation of the original article by the reader allowing him/her to better visualize and comprehend the results. The objective of the present study was to determine the frequency of the adequate use of statistical tests in original articles published in the Revista Brasileira de Anestesiologia from January 2008 to Decembe...

The effect of solid content (2.5-10%, w/v) and temperature (30-70°C) on the viscosity of tapioca meal from three cassava varieties was investigated in this study. Viscosity measurements were conducted using a digital rotational Brookfield viscometer. The viscosity of tapioca meal increased with increasing solid content and decreasing viscometer speeds. An empirical power-law equation fitted the...

Molecular and morphological evidence is presented to support the description of a second species of Pseudophilothrips from Brazil in association with Schinus terebinthifolius, an invasive weedy tree in North America. Pseudophilothrips is here recognized as a weakly defined genus comprising 13 described species from the Americas. This genus is presumably derived from within, rather than sister-g...

Considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. There are two direct and indirect methods tomeasure tensile strength. Since direct methods always encompass difficulties in test setup, indire...
