(
Qatar University
, 1992 , Article)
A comprehensive review of Centaurea species including all the isolated consituents is given. The biological activities of the studied species are also reported.
Indecomposable Representations Of Order Of E6
(
Qatar University
, 1985 , Article)
The extended Dynkin diagram
is a valued graph. We are going to construct a Baechstrom order A associateed to Eg. We prove, by constructions, that the order A of infinite lattice-type but can be listed (tame-type), i.e., ...
Preliminary Observations On The Relative Growth And Production Of Tilapia Species Cultured In Cages At Three Stocking Densities
(
Qatar University
, 1987 , Article)
Relative growth rate and productivity of Tilapia species (T. nilotica and T. galilaea) were studied for fish reared in cages in the Serow fish farm, Egypt. Both species were reared under three different stocking densities ...
Physiological growth analysis of the life-history of calotropis procera (AIT.) AIT. F.
(
Qatar University
, 1992 , Article)
Growth of Calotropis procera was analysed by distribution of dry weight throughout the plant at various stages in growth. Dry biomass, leaf area index, specific leaf area, leaf weight ratio, leaf area ratio, net assimilation ...
Studies On The Trematodes Of The Genus Enenterum Linton, 1910 (Opecoelidae) And The Oenus Pseudocreadium Layman, 1930 (Lepocreadiidae) From Some Red Sea Fish
(
Qatar University
, 1985 , Article)
The genera Enenterum and Pseudocreadium are reviewed. It is suggested that Pseudocreadium indicum Madhavi, 1972 should be considered a synonym of P. balistes Nagaty, 1942. Enenterum pimelopteri Nagaty, 1942, is redescribed ...
Some Histological And Histochemical Aspects Of Egg-Implantation In The Rat
(
Qatar University
, 1987 , Article)
The rat embrayo and uterine epithelium were studied during implantation at 129h p.c., 138h p.c. and 153h p.c., stages. The basophilic bodies found in the iiinpr cell mass and in the uterine epithelium represent dead cells ...

In the eastern Mediterranean, three main water masses are classified: Modified Atlantic Water of Atlantic origin, Levantine Intermediate Water (LIW), formed in winter during storm events and Eastern Mediterranean Deep Water ...
Theory and Computations for Systems Modeled By First Order Differential Equations
(
Qatar University
, 2000 , Article)
A numerical scheme using Sine functions is developed to approximate the solution of a 2 x 2 system of first order differential equations. The error in the approximate solution is shown to converge exponentially.
