abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...
BACKGROUND Fossil fuels' pollution and their non-renewability have motivated the search for alternative fuels. Some common example of seed oils are sunflower oil, date seed oil, soy bean oil. For instance, soy methyl and soy-based biodiesel are the main biodiesel. Biodiesel is a clean diesel fuel that can be produced through transesterification reaction. Recycled cooking oil, on the other hand,...
A new method of constructing optimum constant weight codes over F2 based on a generalized (u,u + v) construction [1]∼ [3] is presented. We present a new method of constructing superimposed code C (h1,h2,··· ,hI) (s1,s2,··· ,sI) bound. and presented a large class of optimum constant weight codes over F2 that meet the bound due to Brouwer and Verhoeff [4], which will be referred to as BV . We pre...
introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...
the present dissertation aims to investigate four-word lexical bundles in applied linguistics research articles by iranian and internationally-published writers. the aims of this study are two-fold: first of all, attempts have been made to create a comprehensive list of the most commonly used four-word lexical bundles categorized by their type and token frequency, their structural characteristi...
Soil contamination by heavy metals is increasing. The biosorption process for removal of the heavy metal Cd(2+) from contaminated soil is chosen for this study due to its economy, commercial applications, and because it acts without destroying soil structure. The study is divided into four parts (1) soil leaching: the relationships between the soil leaching effect and agitation rates, solvent c...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Excessive nitrogen (N) application rates and serious over-exploitation of groundwater under farmer practice threatens the sustainable use resources in North China Plain (NCP). Crop canopy structure affects light distribution between leaves, which is important to determine crop growth. A field experiment conducted from October 2016 June 2019 NCP was designed examine whether optimum water managem...
