Emerging technology has the potential to develop entirely new approaches for producing cellulose fiber-based materials along with fuels and chemical raw like lignin furfural. Rice straw is a rich source of cellulosic fibers inorganic micronic-sized particles termed as ash. They can prove helpful in development or enhanced agricultural residue-based products that offer cost effective substitutes...
in order to study the residues of phosphorous insecticides in mazandaran district of iran, ethion, azinphosmethyl, diazinon and malathion four most used pesticides were chosen and river water samples were collected in april to sept. 2000, throughout the mazandaran state. thin layer chromatography was used, since it was the best applicable method in area with reasonably high level of sensitivity...

در این نوشتار ابتدا به شرح تعاریف مرتبط با آلودگی هوا، انواع آلاینده ها و روش های کنترل و کاهش آلاینده های جوی پرداخته شده است و سپس در ادامه ضمن شبیه سازی انتشار آلاینده، مناسب ترین روش جهت کاهش آلاینده های واحدهای rfccمورد بحث قرار گرفته است. واحد rfcc (residue fluid catalytic cracking) پالایشگاه امام خمینی شازند از خوراک سنگین residue استفاده می کند لذا سطح آلاینده های گوگرد و نیتروژن آن با...
Crop residue burning is the major biomass activity in China, strongly influencing regional air quality and climate. As cultivation pattern China rather scattered intricate, it a challenge to derive an accurate emission inventory for crop burning. In this study, we proposed remote sensing-based method estimate nitrogen oxide (NOx) emissions related at field level over Hubei, China. The new consi...
A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...
introduction: burning mouth syndrome (bms) is defined as burning and pain in the oral mucosa usually without any clinical and laboratory findings. it has a negative effect on patients' quality of life and can be a significant health problem. the aim of this study was to identify major risk factors associated with bms in menopausal and non-menopausal women at dental clinics of gorgan, iran. meth...
Graph burning is a deterministic discrete time graph process that can be interpreted as a model for the spread of influence in social networks. The burning number of a graph is the minimum number of steps in a graph burning process for that graph. In this paper, we consider the burning number of graph products. We find some general bounds on the burning number of the Cartesian product and the s...
