Effect of gamma radiation on the morphology and Thermophysical properties of the pollen wall of Phoenix dactylifera L.
(
Qatar University
, 1994 , Article)
Pollen grains of Phoenix dactylifera were exposed to different doses of gamma radiation (250,500,1000 rad and 1 M rad). To access the effect of radiation on the external morphology of the pollen grains, they were examined ...

The Jurassic to Lower Cretaceous sequences in the wells Abu Hammad-1, Q-71-IX and Kabrit-1, north Eastern Desert of Egypt, have yielded palynofacies assemblages of varying composition. Seven palynofacies types which are ...
Characterization of Polymers in Dilute Solutions
(
Qatar University
, 1997 , Article)
Basic moleculer characterisitics of polymers are: molecular architecture, molecular weight and size, and their distributions. All these characterisitics are derived from measurements of very dilute solutions. Methods of ...
