(
Qatar University
, 1996 , Article)
It was proposed to find out the optimum environmental conditions and nutritional requirements for highest growth regulating substance and enzyme production by Streptomyces olivaceoviridis. The optimum oc-amylase and ...
Collineations Of Polar Spaces
(
Qatar University
, 1990 , Article)
In this paper we consider general embeddable polar spaces with Witt index at least three.
If π : S( ξ) —> S( ξ’) be a thick collineation between polar spaces with i( ξ) =i( ξ’) ≥3. Then there exists a place Ø: k—> k' U ...

Biomass and nutrient cycling are evaluated in sites of Ammophita arenaria and Onoaisvaginalis which are among the most common species growing on the coastal dunes of the western desert of Egypt. Both species accumulate N ...
Approximating the Distribution of Quadratic Forms Using Orthogonal Polynomials
(
Qatar University
, 1999 , Article)
In this paper we propose some techniques to approximate the distribution of quadratic forms in normal random variables. The first two techniques will be based on orthogonal polynomials, namely; the Hermitte and Laguerre ...
Parasites As Indicators Of Environmental Change And Pollution In Marine Ecosystems
