(
Qatar University
, 1996 , Article)
Seventeen strains of Propionibacterium acnes and ten strains of P. granulosum were isolated from acne patients, in addition to ten isolates of each species from healthy persons. All strains were examined for their enzymatic ...
Gravitohydrodynamic Instability Of A Streaming Fluid Cylinder
(
Qatar University
, 1996 , Article)
The capillary-gravitodynamic instability of a self-gravitating fluid cylinder (radius R«) dispersed in a self-gravitating medium of negligible motion has been developed. General stability criteria are derived, upon utilizing ...
Sulphur Oxidation In Saudi Arabian Agricultural Soils

In this paper we study the inverse problem on the half line for a generalized stationary one dimensional Schrodinger equation. We consider the solutions of the differential equation and study its properties. Given the ...
Plant Population Density Effects On Yield Of Sorghum Grown In A Dry-Land Farming System
(
Qatar University
, 1996 , Article)
Plant population studies in arid regions are very sparse and not well documented. A prerequisite in growing a successful sorghum (Sorghum bicolor [L.] Moench) crop is to obtain an adequate plant population. The response ...
Impulse Breakdown Characteristics In Air In The Presence Of A Local Spark
