Gamma Irradiation of 4th Instar Larva of Angoumois Grain Moth and Effects on Parent and Their Generations
(
Qatar University
, 2006 , Article)
Late fourth stage larvae of Angomous grain moth, Sitotroga cerealella (Olivier) were gamma irradiated with doses 0 ( control), 25, 50 75, 100, 125 and 150 Gy. The moths originated from larvae irradiated with 150 Gy became ...
Comparative Study of 11 Honey Samples Sold in Riyadh Saudi Arabia
(
Qatar University
, 2006 , Article)
11 honey various samples commercially available in Saudi Arabia, were subjected to chemical, toxicological and bacteriological tests. The samples were checked for As and CN, presence of pollens, and for bacteria contamination. ...
Reproducing Formula and Algorithm of a Familv of Biorthonormal Wavelets
(
Qatar University
, 2005 , Article)
In this paper we present a family of biorthonormal wavelets generated by a MRA orthonormal wavelet, which possesses two arbitrary parameters. Then we discuss new expressions of reproducing kernel as well as the corresponding ...
Halophytes and Soil Salinity in Qatar
(
Qatar University
, 2002 , Article)
Saline soils cover approximately 6% of the land in Qatar. Halophytes are common along the coastal areas and inland salt flats and wetlands, where saline water is available in their natural habitats permanently or periodically. ...
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 ...
Separation of Two Forms of Extracellular p-glucosidase From a Thermotolerant Aspergillus niveus
(
Qatar University
, 2003 , Article)
Two forms of P-glucosidase ((3-D-glucoside glucohydrolase, EC 3.2.1.21) from the culture filtrate of Aspergillus niveus were separated and partially purified by gel chromatography on Sephadex G-100 column. The two forms ...
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 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 ...
Addressing Cloud Computing in Enterprise Architecture: Issues and Challenges
(
Cutter Consortium
, 2009 , Article)
This article discusses how the characteristics of cloud computing affect the enterprise architecture in four domains: business, data, application and technology. The ownership and control of architectural components are ...
Digitally-tuned resolver converter
(
Elsevier B.V.
, 2009 , Article)
Sinusoidal encoders provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. ...
