the purpose of this study was to investigate economic impacts (including production costs, mechanization growth, changes in productivity per area, changes in the size of the cultivated area and productivity of production inputs) and ecological impacts (including protecting the environment from degradation and soil erosion as well as sustainable use of chemical fertilizers) of rural agricultural...
returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. in addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
abstract incorporation of plant residues in soils is an important agricultural practice for maintaining soil fertility under organic management systems. plant residues quality, soil physical and chemical properties, and the microbial population diversity of soils are the most important factors influencing the decomposition of added organic matter to soils. decomposition rate of municipal wastes...
In this study, solid-state fermentation of two types of agricultural residues/products for lipase production in a tray-bioreactor was investigated. Rhizopus oryzae was used as a potential fungus strain and two types of agricultural residues including soybean meal and sugarcane bagasse were utilized as substrate. Fermentation was carried out in two different operational conditions: one with cont...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
