On Special Generalized Douglas-Weyl Metrics
(University of Tehran, 2012-06-01)In this paper, we study a special class of generalized Douglas-Weyl metrics whose Douglas curvature is constant along any Finslerian geodesic. We prove that for every Landsberg metric in this class of Finsler metrics, ? = ...

Bound Putrescine, a Distinctive Player under Salt Stress in the Natrophilic Sugar Beet in Contrast to Glycophyte Tobacco
(University of Tehran, 2012-06-01)The influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (Beta vulgaris L. cv. IC) and a salt sensitive glycophyte (Nicotiana rustica L. cv. ...

Synthesis and in vitro Evaluation of the Antimycobacterial Activity of N-aryl-1,4-dihydropyridine-3,5-dicarboxamides
(University of Tehran, 2012-06-01)Dihydropyridines (DHPs) with carboxamides in the 3 and 5 positions show anti-tuberculosis activity. The purpose of the present study was to synthesize new DHPs that would possibly possess anti-tuberculosis activity. So a ...
