المياه المعبأة في دولة قطر مع دراسة سلوك مستهلكيها
(
Qatar University
, 2005 , Article)
يهدف البحث إلى التعرف على وقع صناعة المياه المِعبأة في دولة قطر وتجارتها وكذلك جودتها مقارنة مع مياه الشبكة العامة. وًمن بين الأهداف أيضا درًاسة سلوك مستهلكيها وتبني خطة لتطوير صناعتها. وقد اعتمد الباحثان على مصادر بيانات ...
Fixing the Kingdom: Political Evolution and Socio-Economic Challenges in Bahrain
(
Georgetown University School of Foreign Service in Qatar
, 2008 , Article)
Bahrain has entered into a more ‘progressive’ phase of its history under King Hamad bin Isa Al Khalifa. Various parliamentary and legislative restructuring, in addition to discernable changes within civil society, have ...
On the numerical simulation of population dynamics with density-dependent migrations and the Allee effects
(
IOP Publishing
, 2008 , Article)
In this paper, the variational iteration method (VIM) and the Adomian decomposition method (ADM) are presented for the numerical simulation of the population dynamics model with density-dependent migrations and the Allee ...
The modified homotopy perturbation method for solving strongly nonlinear oscillators
(
Elsevier
, 2009 , Article)
In this paper we propose a reliable algorithm for the solution of nonlinear oscillators. Our algorithm is based upon the homotopy perturbation method (HPM), Laplace transforms, and Padé approximants. This modified homotopy ...
On the Lp boundedness of rough parametric Marcinkiewicz functions
(
Victoria University
, 2007 , Article)
In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]).
Knockout mice: Is it just genetics? Effect of enriched housing on fibulin-4+/- mice
(
Public Library of Science
, 2007 , Article)
Background. Fibulin-4 is an extracellular matrix protein expressed by vascular smooth muscle cells that is essential for maintaining arterial integrity. Fibulin-4-/- mice die just before birth due to arterial hemorrhage, ...
On the 'independence of trials-assumption' in geometric distribution
(
Taylor & Francis, Ltd
, 2008 , Article)
In this note, it is shown through an example that the assumption of the independence of Bernoulli trials in the geometric experiment may unexpectedly not be satisfied. The example can serve as a suitable and useful classroom ...
An upper bound of the basis number of the semi-strong product of cycles with bipartite graphs
(
The Korean Mathematical Society
, 2007 , Article)
An upper bound of the basis number of the semi-strong product of cycles with bipartite graphs is given. Also, an example is presented where the bound is achieved.
Weighted estimates for rough parametric Marcinkiewicz integrals
(
Korean Mathematical Society
, 2007 , Article)
We establish a weighted norm inequality for a class of rough parametric Marcinkiewicz integral operators . As an application of this inequality, we obtain weighted inequalities for a class of parametric Marcinkiewicz ...
Numerical bifurcation of predator-prey fractional differential equations with a constant rate harvesting
(
IOP Publishing
, 2008 , Article)
In this article saddle and Hopf bifurcation points of predator-prey fractional differential equations system with a constant rate harvesting are investigated. The numerical results based on Grunwald-Letnikov discretization ...
