Two Forms Of The Backlund Transformation Of A Third Order Differential Equation
( Qatar University , 1996 , Article)Two explicit forms of Backlund transformation of third order dispersive differential equation are derived. The method of derivation depends on the use of a transformation that couples the equation with its modified one. -
Two Notes On Modular P-Algebras
( Qatar University , 1988 , Article)According to the definition of congruence .pairs which is given by T. Katrinak, every congruence relation of a modular p-algebra can be uniquely determined by a congruence pair. In the present paper, we characterize strong ... -

( Qatar University , 1982 , Article) -
Ultrasonic C-Scan Inspection Of Composite Materials
( Qatar University , 1992 , Article)Ultrasonic technique using an automated C-scan has been established as the primary inspection method for composite materials. In this paper, the principles of ultrasonic inspection, the type of defects that may be generated ... -
Ultrasonic Characterization, Tensile Testing And Thermal Properties Of Y Irradiated Low Density Polyethylene, Fb 5005
( Qatar University , 1997 , Article)Ultrasonic pulse-echo technique, tensile testing and thermal gravimetric analysis have been utilised to characterise and monitor the effect of y irradiation on the physicomechanical properties of low density polyethylene ... -
Ultrasonic Pulse Velocity Versus Strength For Concrete In Qatar
( Qatar University , 1992 , Article)Compressive strength of concrete is widely accepted as a characteristic property indicating and representing its quality. The accuracy of both ultrasonic and mechanical strength is discussed and the advantages of ultrasonic ... -
Ultrastructural localization of acid and alkaline Phosphatases, glucose-6-phosphatase and odium-potassium Atpase enzymes in the neurosecretory and oesophageal Cells of earthworm
( Qatar University , 1994 , Article)In the present study we have localized acid and alkaline phosphatases, glucose-6-phosphatase and sodium-potassium ATPase (Na-K-ATPase) in ultra-thin sections of cerebral neurosecretory cells and oesophageal cells of the ... -
ultrastructural observations on the effect of the insecticide "aldrin" on some neurosecretory cells of the cerebral ganglion of the earthworm aporrectodea caliginosa
( Qatar University , 1994 , Article)The effect of the insecticide "Aldrin" on the neuroglia and neurosecretory cells of the earthworm Aporrectodea caliginosa was studied. The fine changes on the organdies of certain neurosecretory cells was observed by light ... -
