A study on friction coefficient and wear coefficient of coated systems submitted to micro-scale abrasion tests
(2013)
Several works on friction coefficient during abrasive wear tests are available in the literature, but only a few were dedicated to the friction coefficient in micro-abrasive wear tests conducted with rotating ball. This ...
EVALUATION OF DIFFUSION-COEFFICIENTS IN OSMOTIC CONCENTRATION OF BANANAS (MUSA-CAVENDISH LAMBERT)
(Blackwell Science, 1995-04-01)
The effect of time of exposure, solution concentration and temperature on the osmotic concentration of banana (slices of 11 mm thickness) was studied in aqueous sucrose solutions. The selectivity of the cellular tissues ...
Connection coefficients and zeros of orthogonal polynomials
(Elsevier B.V., 2001-08-01)
We discuss an old theorem of Obrechkoff and some of its applications. Some curious historical facts around this theorem are presented. We make an attempt to look at some known results on connection coefficients, zeros and ...
Zeros of Gegenbauer and Hermite polynomials and connection coefficients
(Amer Mathematical Soc, 2004-01-01)
In this paper, sharp upper limit for the zeros of the ultraspherical polynomials are obtained via a result of Obrechkoff and certain explicit connection coefficients for these polynomials. As a consequence, sharp bounds ...
Population structure and genetic variability in the Murrah dairy breed of water buffalo in Brazil accessed via pedigree analysis
(Springer, 2012-12-01)
The objective of this study was to use pedigree analysis to evaluate the population structure and genetic variability in the Murrah dairy breed of water buffalo (Bubalus bubalis) in Brazil. Pedigree analysis was performed ...
INFLUENCE OF ABRASIVE WEAR MODES ON THE COEFFICIENT OF FRICTION OF THIN FILMS
(2018-11-05)
The purpose of this work is to study the influence of abrasive wear modes on the coefficient of friction (μ) of thin
films. Initially, free rotative-ball micro-abrasive wear testing equipment was designed and constructed ...

Coeficientes de perda de carga em valvulas e acessorios no escoamento laminar de fluidos nao-Newtonianos
(2000-01-01)
Friction loss coefficients for laminar flow of xantan gum solutions (concentrations in the range of 0.1-0.5% by weight) through valves and fittings were experimentally determined. The rheological behavior, studied by means ...
