The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...
in order to evaluate the effects of crop cultivars and living mulchon sunflower yield and weed control, a field experiment was carried out as factorial arrangement based on a randomized complete block design with three replications in 2013. treatements were sunflower cultivars (‘azargol’, ‘allstar’, ‘farokh’) and weed control treatments (weed-free, weed-infestation and intercropping of fagopyru...
Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...

This article aims discuss how was implemented and its effect on health, performance quality product as well development strategies an alternative systems. The must have access outdoor express their natural behavior. Based regulation, density chickens in maximum 10,0...
Adenoviruses (Ad) have a long history as DNA-transfer vehicles in various medical applications including vivo gene therapy [1]. In this context, the favorable safety profile of Ad has been considered major benefit, since lack integration into host cell genome eliminates potential risks associated with insertional mutagenesis. This is combined comparatively high packaging capacity for foreign DN...
