A generalized differential transform method for linear partial differential equations of fractional order
(
Elsevier B.V.
, 2007 , Article)
In this letter we develop a new generalization of the two-dimensional differential transform method that will extend the application of the method to linear partial differential equations with space- and time-fractional ...
Possible Ionic Effects of NaCl on Two Mexican Wheat Cultivars
(
Qatar University
, 2005 , Article)
The effect of NaCl on growth and physiology of two Mexican wheat (Triticum asestivum L) cultivars (Cajeme: salt tolerant, and Yecora: salt sensitive) was compared with that of other osmotic agents, Na2SOa (ionic compound) ...
Numerical methods for nonlinear partial differential equations of fractional order
(
Elsevier B.V.
, 2008 , Article)
In this article, we implement relatively new analytical techniques, the variational iteration method and the Adomian decomposition method, for solving nonlinear partial differential equations of fractional order. The ...
Convergence theorems for nonself asymptotically nonexpansive mappings
(
Elsevier B.V.
, 2007 , Article)
In this paper, we prove some strong and weak convergence theorems using a modified iterative process for nonself asymptotically nonexpansive mappings in a uniformly convex Banach space. This will improve and generalize the ...
Relationship of plant proteins and amino acids within taxonomic categories in Qatari range plants
(
Asian Publication Corporation
, 2005 , Article)
Protein and amino acids of sixty-eight range plants growing wild in Qatar belonging to fifty-six genera and twenty-three families are studied to evaluate their nutritive values
Application of homotopy-perturbation method to fractional IVPs
(
Elsevier
, 2008 , Article)
Fractional initial-value problems (fIVPs) arise from many fields of physics and play a very important role in various branches of science and engineering. Finding accurate and efficient methods for solving fIVPs has become ...
A rich learning lesson using the Poisson distribution
(
Elsevier B.V.
, 2007 , Article)
In this note, we explore the rich information about inference that the Poisson distribution has. The source of this information is mainly the fact that the mean and variance of this distribution are equal.
Kinetics and Mechanistic Studies of the Bromination of Some Substituted Tetralones, Part 1
(
Qatar University
, 2000 , Article)
The rate of bromination of 2-benzal-l-tetralone (II) and its derivatives p-methyl (12), 77-chloro (13), ffi-chloro (14), and p-nitro (15) have been studied in chloroform. The study indicated first order dependence on each ...
The effect of two substituents on different organoselenides and tellurides to form new charge-transfer complexes
(
Qatar University
, 2004 , Article)
Different organotellurides and selenides were prepared as electron donors and reacted with p-Benzoquinone (p-BQ) and m-Dinitrobenzene (m-DNB) as electron acceptors .
The resulted molecules were considered as new ...
