objective: the objective of this study was analyzing the effect of meta-cognition elements on depression, trait and state anxiety symptoms.  methods: in this study, the sample consisted of 224 students of university of social welfare and rehabilitation sciences that answered three questionnaires including metacognitive questionnaire (mcq-30), beck depression inventory (bdi-ii) and spielberger s...

using the lennard-jones (12-6) potential, a new equation of state is obtained that can predict properties of both gases and liquids relatively well. this equation of state is given as (z-a)v2=(a/v2)-b, where z is the compressibility factor, a and b are constants, and a is an adjustable parameter that depends on the temperature, volume and the nature of the fluid, and its expressions depends upo...

a diverse range of foods has been shown to increase energy and micronutrients intake in the developing countries. it is widely asserted in the literature and development circles that farm household access to irrigation dam can provide a significant improvement of household’s dietary diversity. this study set out to assess the role of kampe irrigation dam on farm household dietary diversity in k...

a solid state fermentation method was developed for the production of citric acid from date pulp (obtained of date syrup production from the process) by aspergillus niger ptcc 5010. poor yield was obtained when potassium ferrocyanide treated date pulp were used as substrate, but methanol at a 3-4% concentration markedly increased the forma-tion of citric acid from the waste. the optimum range o...

in this report, we present a facile approach for the synthesis of luminescent cds and cds:mn+2 nanocrystals by reaction of cdso4 and na2s2o3 in the presence of thioglycerol (c3h8o2s) as capping agent. the influence of various experimental variables including, ph values and percentage of dopant, on the growth rate and optical properties of the obtained cds nanocrystals has been systematically in...

the state of post revolutionary iran adopted economic policies over 1980-1988 which we can phrase redistributive economic policies. according to a part of revolutionary literature, adoption of these policies by the post revolutionary state is, partly, one of the structural features of that state. but it is not a main debate of this article. rather, basic concern of the article, as some of the p...

the capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. in this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. to this aim, constitutive equations of a state dependent sand model are explained first. consequently, the general ...

an analytical equation of state by song and mason is developed to calculate the pvt properties ofmercury. the equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. there exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...

In this paper, we enlarge the language of triangle algebra by addinga unary operation that describes properties of a state. Thesestructure algebras are called state triangle algebra. The vitalproperties of these algebras are given. The notion of state interval-valued residuated lattice (IVRL)-filters are introduced and givesome examples and properties of them are given. ...
