Production of biodiesel from edible vegetable oils using homogenous catalysts negatively impacts food availability and cost while generating significant amounts caustic wastewater during purification. Thus, there is an urgent need to utilize low-cost, non-food feedstocks for the production sustainable heterogeneous catalysis. The objective this study was synthesize a novel supported nano-magnet...

for determination of economic damage threshold of four wheat (triticum aestivum l.) cultivars in different densities of wild mustard (sinapis arvensis l.), experiments were conducted at agricultural research station gorgan during 2010-2012. the experimental design consisted of four randomized complete blocks in a factorial arrangement. the treatments comprised of factorial combination of wild m...

to evaluate the effect of different levels of nitrogen fertilizer on growth indices and competitive ability of canola (brassica napus l.) against wild mustard (sinapis arvensis l.), a split plot trial based on a randomized complete block design with three replications, was carried out at agricultural faculty of bu-ali sina university, during 2008-2009. experimental factors were amounts of nitro...

Presently, chemical control is the most used method for plant protection. However, it not an approach that environmentally sustainable. Alternative IPM methods include biological such as Allelopathy can be a good alternative in protection.Allelopathy defined direct or indirect interaction, whereby allelochemicals released by one organism influence physiological processes of other neighboring or...

A novel Li-impregnated TiO2 catalyst loaded on feldspar mineral (Li-TiO2/feldspar) was synthesized via a wet impregnation method and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) analysis. Using these techniques, it possible to confirm the catalyst’s structural organization with high crystallinity. This used in transesterifica...
