Selectivity Coefficient Of Wire Basket Traps For Tilapia Nilotica
( Qatar University , 1984 , Article)Most methods of estimating growth and mortality rates require samples representative of the population with respect to size of one or more age groups. There is no fishing gear that exhibits equal selectivity towards fish ... -
A Self-Organizing Multisensor Fusion Classification Algorithm
( Qatar University , 1996 , Article)A self-organizing multisensor fusion algorithm to classify the inputs (data or images) into classes (targets, backgrounds) is presented. The algorithm forms clusters and is trained without supervision. The clustering is ... -
Sem Studies On Facilitated Microbial Growth On Pac In A Biological Reactor
( Qatar University , 1996 , Article)A process known as powdered activated carbon (PAC) treatment was applied to facilitate additional bacterial growth in the treatment of industrial wastewater. Refinery wastewater was fed into a pilot plant reactor at a rate ... -
Senso-Neuroendocrine Cells Within The Cerebral Ganglion Of The Earthworm Aporrectodea Caliginosa
( Qatar University , 1992 , Article)Ciliated neurones of probable endocrine function are present inside and outside the cerebral ganglion of the earthworm Aporrectodea caliginosa. Cell fibers contain clusters ofsynaptoid vesicles in regions adjacent to the ... -
Separation and preconcentration of malathion and azamethiphos by Unloaded polyurethane foams
( Qatar University , 1994 , Article)The feasibility of using unloaded polyether type polyurethahe foams for the extraction and separation of malathion and azamethiphos in batch and column operations has been examined. The effects of pH, ionic strength, shaking ... -
Separation of Two Forms of Extracellular p-glucosidase From a Thermotolerant Aspergillus niveus
( Qatar University , 2003 , Article)Two forms of P-glucosidase ((3-D-glucoside glucohydrolase, EC 3.2.1.21) from the culture filtrate of Aspergillus niveus were separated and partially purified by gel chromatography on Sephadex G-100 column. The two forms ... -
Sequence Of Ossification In The Skeleton Of Growing Lizard Chalcides Ocellatus Forscal (Scincidae, Reptilia)
( Qatar University , 1988 , Article)The distribution of cartilaginous and ossification rudiments were described in the live-bearing lizards, Chalcides ocellatus, at birth, one-month-old, and 12-month-old. The skeletal elements investigated are: neurocranium, ... -
Serum And Tissue Enzymes And Trace Elements In Hamsters With Schistosomiasis Mansoni And/Or Protein Energy Malnutrition
( Qatar University , 1996 , Article)Schistosomiasis is mostly widespread in communities suffering from protein energy malnutrition. The development of an animal model for each condition is required for better understanding of changes in certain biochemical ... -
Setting standards for criterion-referenced measurement
( Qatar University , 1983 , Article)Improving human resources is the responsibility of the educational system in many societies. The outputs of the educational systems are, in many ways, the inputs of other systems found in societies. Life today in many ... -
