attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
In order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of Abadeh city.Experiments were conducted in a randomized complete block design, with five treatments and five replications.In the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...
cadmium is one of the most toxic pollutants in the surface soil layer the accumulation of which in soils as well as in crops is of increasing concern. in addition, zinc is a micronutrient in rice nutrition which is in interaction with cd. a pot experiment was carried out to study the effects of zinc and cadmium on rice growth and as well on concentrations of zn, cd, fe and mn in soil. a factori...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
Purslane (Portulaca oleracea L.) contains valuable ingredients such as dopamine, noradrinalin and omega-3. The increase of secondary metabolites by elicitors is widely used in tissue culture of medicinal plants. The aim of this study was to assess effect of plant growth regulators on callus induction and amount of dopamine in callus tissue of purslane under the influence of methyl jasmonate as ...
