Chemical fertilizers have important role in modern agriculture, and in the other hand led to rigid environmental pollution. Urea fertilizer is one of the most widely used and least expensive nitrogen fertilizers in Iran. Since it is high solubility in water a significant of it, if irrigation or precipitation is heavy, easily washed and led to change to change the quality of groundwater, rivers ...
Consider a set of K alternatives. We say that an alternative is socially acceptable if the number of individuals that rank it among their most preferred half of the alternatives is at least as large as the number of individuals that rank it among the least preferred half. A Condorcet winner is not necessarily socially acceptable. We propose a concept of consensus as a condition on preference pr...
Although the Individuals Education Act (IDEA, 1990; 1997) has provided a national mandate to help high school students with disabilities grow into independent adults, youth with emotional and behavioral difficulties continue to experience considerable problems transitioning into adulthood. Their adjustment into socially acceptable adult roles has been examined in a number of follow-up and follo...
This paper deals with the problem of scheduling optimal advertising policy for a very general class of consumer buying behavior models. To avoid analysis of a complex multitude of social-psychological and cultural-environmental factors affecting the consumer’s decision we construct a stochastic model. Because of the diminishing effect of even advertising policy, we consider advertising pulsing ...
Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...
In order to study the effect of irrigation interval, N fertilizer and superabsorbent on yield and qualitative traits of sesame (Sesamum indicum L.), a split-split-plot experiment was coducted in a farm in Khusf of Birjand, Iran in 2009 on the basis of a Randomized Complete Block Design. The main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...
201 Modern society has placed a high premium on good health, a lean body, and comeliness. As a nation we eat better, exercise more, and seek a healthier lifestyle to achieve physical well being. A national consensus seems to exist that a well-proportioned body is a thing of beauty. It is no wonder, therefore, that obesity, a caricature of the beautiful body, has been responsible for ridicule an...
A six year field study was conducted from 2001–2002 to 2006–2007 at Punjab Agricultural University, Ludhiana, India to study the losses in seed yield of different Brassica species (B. juncea, B. napus, B. carinata, B. rapa and Eruca sativa) by the infestation of insect pests. The experiment was conducted in two different sets viz. protected/sprayed and unprotected, in a randomized block design,...
