چکیده در سالهای اخیر افزایش کسری بودجه بدون درآمدهای نفتی در ایران به لحاظ استقلال مالی دولت و کاهش وابستگی از نفت به مرز نگران کننده ای رسیده است . در سال 1395 این عدد به 103هزار میلیارد ریال در قانون بودجه افزایش داشته است .به دلیل انکه آزادی اقتصادی ، محدوده بازار را رقم زده و حوزه های دخالت دولت در اقتصاد را مشخص می کند ، از این جهت در این مقاله کوشش شده است فرضیه رابطه معکوس بین درجه آزاد...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
Employing extensive quantum-chemical calculations at the DFT/B3LYP and MP2 level, quartic force fields of isolated N-methylacetamide are constructed. Taking into account 24 vibrational degrees of freedom, the model is employed to perform numerically exact vibrational configuration interaction calculations of the vibrational energy relaxation of the amide I mode. It is found that the energy tran...
We develop a theory of the effective disorder temperature in glass-forming materials driven away from thermodynamic equilibrium by external forces. Our basic premise is that the slow configurational degrees of freedom of such materials are weakly coupled to the fast kinetic-vibrational degrees of freedom and therefore that these two subsystems can be described by different temperatures during d...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
Soft, amorphous solids such as tissues, foams, and emulsions are composed of deformable particles. However, the effect single-particle deformability on collective behavior soft is still poorly understood. We perform numerical simulations two-dimensional jammed packings explicitly particles to study mechanical response model solids. find that with excess shape degrees freedom possess low-frequen...
