Trace Metals in Wastewater Ponds in Qatar
(
Qatar University
, 2002 , Article)
A one-year monitoring program was conducted to determine the extent of metal contamination in two wastewater ponds in Qatar. Abu-Hamour pond receives untreated domestic and industrial waste while Abu-NakhIa pond receives ...
On Symboloic Reasoning and Direct Inference Principle
(
Qatar University
, 2004 , Article)
This paper discusses an approach using the M-valued symbolic logic with syllogistic reasoning and direct inference principle (reasoning from statistical information to conclusions about individuals), to manipu¬late statistical ...
Generalized dynamic spectrum access: An order statistics design perspective
(
Elsevier GmbH
, 2008 , Article)
A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ...
Effect of Different Doses of Inorganic Fertilizer on Water Quality, Primary Productivity and Production of Nile Tilapia (Oreochromis niloticus) in Earthen Ponds
(
Qatar University
, 2002 , Article)
Earthen ponds (surface area 155 m2 each) were used to study the effect of different doses of inorganic fertilizer on water quality and fish production. Each pond was stocked with 150 fish of Nile tilapia; Oreochromis ...
Geochemistry and Petrogenesis of a Late Proterozoic Volcanic Sequence in the Magal Gebriel Area, South Eastern Desert, Egypt
(
Qatar University
, 2000 , Article)
Metabasalts and meta-andesites together with small amounts of metadacite constitute the Magal Gebriel volanic suite. Restricted amounts of unmetamorphosed rhyolitic rocks are also present. The metavolcanics show a wide ...
Gravitational Instability of a Radiating Gas Cloud with Variable streams
(
Qatar University
, 2001 , Article)
The self-gravitating instability of a radiating gas cloud possessing variable streams is investigated. The self-gravitating force is destabilizing according to restrictions, the radiation has a strong stabilizing influence ...
Experimental Investigation of the N-Pbs/P-Si Heterojunction Band Lineup with I-V and C-V Measurements
(
Qatar University
, 2005 , Article)
In this paper we present experimental investigation of band lineup of near ideal PbS/Si heterojunction diode using I-V and C-V measurements. The C-V measurements show that the fabricated diodes were abrupt type, and the ...
Genotoxicity and Embryotoxicity of the Insecticide Primicid in Chick Embryo
(
Qatar University
, 2000 , Article)
Growing chick embryos were treated with primicid to examine the cytogenetic and embryotoxic effects of this insecticide. For the cytogenetic assay, eggs were injected through the air chamber with primicid at a concentration ...
