lisianthus (eustoma grandiflorum cv. ‘mriachii blue’) is one of the most important and marketable cut flowers in the world. however, a relatively limited vase life reduces its marketability. the aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of lisianthus. for this purpose a factorial experiment based on a completely randomized desig...

Dear Editor, In response to the criticisms regarding the article entitled; “association of hyperhomocysteinemia with coronary artery disease in Southern Iran”, published in Iran J Med Sci,1 we still believe the methodology used in this study was a case control design as the cases where chosen on the basis of outcome (coronary artery disease) and the controls were individuals without the disease...

abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...

Relative to a hereditary torsion theory $tau$ we introduce a dimension for a module $M$, called {em $tau$-rank of} $M$, which coincides with the reduced rank of $M$ whenever $tau$ is the Goldie torsion theory. It is shown that the $tau$-rank of $M$ is measured by the length of certain decompositions of the $tau$-injective hull of $M$. Moreover, some relations between the $tau$-rank of $M$ and c...
