, 1990 , Article)
The detailed study of the Upper Cretaceous-Lower Tertiary succession exposed in Beris-Doush area enabled the subdivision of this succession into a number of rock units well known in the Nile Valley facies area in Egypt. ...
On the direct problem and scattering data for a singular system of differential Equations with discontinuous coefficients
(
Qatar University
, 1996 , Article)
A system of Sturm-Liouiville differential equations of order n with a density matrix function is considered. The direct problem of the considered system is studied and hence the scattering data of the problem is obtained.
Thermal Acclimation In The Resting Metabolism Of The Nocturnal Gecko, Hemidactylus Flaviviridis
(
Qatar University
, 1996 , Article)
Hemidactylus flaviviridis was acclimated to two temperature regimes (20 and 30°C). The resting metabolic rates (ml g1 h"1) were determined at 20, 25,30 and 35°C, using constant pressure manometric respirometers. The 20°C- ...
Decomposition of a Special Type of Machines
(
Qatar University
, 1994 , Article)
In this paper, the concept of a finite n-state cyclic machine An is defined. These machines are then completely characterized using the prime factorization of n. Specifically, it is proved that any finite-state cyclic machine
