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 ...
Molecular phylogeny of Qatari date palm genotypes using Simple Sequence Repeats markers
(
Asian Network for Scientific Information
, 2009 , Article)
The objectives of the present study is to analyze the genetic diversity among 15 different cultivars of date palm at the experimental farm of Qatar University using Simple Sequence Repeat (SSR) markers and find out the ...
Viscous-Gravity spreading of oil on water
(
John Wiley & Sons, Inc.
, 2001 , Article)
Spreading of oil on calm water is analyzed for the second stage of spread, which is controlled by a balance between gravity and viscous forces. The analysis, using the integral boundary-layer method, agreed well with a ...
Highly accurate solutions of the bifurcation structure of mixed-convection heat transfer using spectral method
(
John Wiley & Sons, Ltd.
, 2002 , Article)
This paper is concerned with producing highly accurate solution and bifurcation structure using the pseudo-spectral method for the two-dimensional pressure-driven flow through a horizontal duct of a square cross-section ...
New Heuristic Strategies for Reactive Power Compensation of Radial Distribution Feeders
(
IEEE
, 2002 , Article)
In this paper, the authors introduce two new heuristic techniques for reactive power compensation in radial distribution feeders. The methods can be considered as generalization ideas that emerged from recent heuristic ...
Photodegradation of methylene blue dye by the UV/H2O2 and UV/acetone oxidation processes
(
Elsevier B.V.
, 2005 , Article)
The photodegradation of methylene blue (MB) dye in aqueous solutions was investigated using a laboratory-scale UV lamp in the presence of hydrogen peroxide (H2O2). Different initial concentrations of dyes (10, 20, 30, 40 ...

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 ...
Self-Imaging based Dispersion Compensation: Performance and Tolerance of the System
(
IEEE
, 2007 , Article)
Transmitting ultra wideband (UWB) pulse signals over optical fiber is a certain sign of chromatic dispersion (CD) existence. CD is a serious problem in optical transmission because the velocity of light depends on the ...
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, ...
