The Scientific Contributions of Arab Scientists to the International Research: a Study of the Indicators for Select Arab Countries
(
Blackwell Publishing Ltd
, 2009 , Article)
Using SCOPUS database, the research productivity of Arab researchers in five countries has been investigated. The analysis included subject, geographical and time range indicators. The relationship between the most published ...
The Structure of the Free Volume in Poly(styrene-co-acrylonitrile) from Positron Lifetime and Pressure Volume Temperature (PVT) Experiments
(
WILEY-VCH Verlag
, 2004 , Article)
Summary: The structure of the free volume and its temperature dependence between 25 and 190 °C of copolymers of styrene with acrylonitrile, SAN (0 to 50 mol-% AN), is studied by pressure volume temperature (PVT) experiments ...
Man-made impact on the geochemistry of the Nile delta lakes. A study of metals concentrations in sediments
(
Kluwer Academic Publishers
, 2004 , Article)
Forty two sediment samples were collected from four River Nile northern delta lakes (Mariut, Edku, Burullus and Manzalah) to asses the man-made impact on their environment during the last 20 years. Due to the continuous ...

Theoretical study of laser light generation and color image formation: FA1:Cs+ and FA2:Li+ centers at the low coordination (100) and (110) surfaces of AgCl and AgBr
(
Wiley Periodicals, Inc.
, 2005 , Article)
The FA1:Cs+ and FA2:Li+ color centers at the low coordination (100) and (110) surfaces of AgCl and AgBr play important roles in laser light generation and color image formation. Double-well potentials at these surfaces are ...
Maintaining the genetic health of putative Barbary lions in captivity: an analysis of Moroccan Royal Lions
(
Springer Berlin / Heidelberg
, 2009 , Article)
The last representatives of the Barbary lion (Panthera leo leo), once numerous in North Africa but exterminated from the wild by the 1940s, are believed to be the captive lions descended from the Moroccan Royal Collection, ...
On the estimation of reliabilty function in a Weibull lifetime distribution
(
Taylor & Francis
, 2008 , Article)
The estimation of the reliability function of the Weibull lifetime model is considered in the presence of uncertain prior information (not in the form of prior distribution) on the parameter of interest. This information ...
Sinc-based computations of eigenvalues of Dirac systems
(
Springer Netherlands
, 2007 , Article)
The celebrated classical sampling theorem is used to compute approximate values of the eigenvalues of Dirac systems with eigenvalue parameter in the boundary conditions. We deal with problems with an eigenparameter in one ...
One and two sample confidence intervals for estimating the mean of skewed populations: an empirical comparative study
(
TAYLOR & FRANCIS LTD
, 2009 , Article)
In this paper we consider and propose some confidence intervals for estimating the mean or difference of means of skewed populations. We extend the median t interval to the two sample problem. Further, we suggest using the ...
