Annealing Behaviour, Tcr Values And Defect Density For "Cold-Condensed" Silver Films
( Qatar University , 1990 , Article)Thin silver films were deposited under vacuum of 10^ -6 Torr by thermal evaporation onto cooled glass substrates kept at low temperatures. Pure argon gas prevailed as residual gas. Annealing behaviour of the electrical ... -
Antibacterial and antidermatophyte activities of some essential Oils from spices
( Qatar University , 1993 , Article)The inhibitory effects of ten essential oil from different spices against the growth of various isolates of bacteria representing Gram-positive (seven isolates) and Gram-negative (four isolates) were studied. Eight ... -

Apical dominance in vicia faba l.
( Qatar University , 1983 , Article)A side-effect of plant surgery was an interference with apical dominance. From the results of three experiments involving plant surgery, decapitation and the usage of "C-IAA, it appeared that the movement of the apically ... -
The Appendicular Skeleton In The Hatching And In Young Bunopus Tuberculatus Blanford, 1874 (Gekkonidae, Reptilia)
( Qatar University , 1988 , Article)The appendicular skeleton and its calcification are described in Bunopus tuberculatus at 3 ages: at hatching, 6-month-old and 12-month-old. Between the 3 ages there are several differences in the osteological pattern. The ... -
Application Of Artificial Neural Networks To Predict Wettability And Relative Permeability Of Sandstone Rocks
( Qatar University , 1996 , Article)An Artificial Neural Network (ANN) model based on the back-propagation technique is trained with a number of variables from experimentally established relative permeability curves. The reservoir core input data covers an ... -
Application Of Different Methods For The Preparation Of Chlorophyll Pigments For Food And Pharmaceutical Industries
( Qatar University , 1994 , Article)The main objective of this work is to establish an economic and applied technique for the production of chlorophyll pigments and their derivatives namely Cu-chlorophyll complex in the form of colour additives. These trials ... -
Application of discriminant score /∆ log r method for prediction of Organic richness at negelah well, coastal Mediterranean zone, western desert Egypt
