background and objectives: bacillus species are attractive industrial organisms due to their rapid growth rates leading to a short fermentation cycle and for their capacity to secrete important enzymes and proteins such as xylanase into the extracellular medium. considering the industrial importance of xylanase, in this current study, bacillus spp. were isolated from different soils and were sc...

perfectionism, in fact, is an irrational belief individuals have about themselves and their surroundings. perfectionists believe that they and their surroundings must be complete and any attempt in life must be without error. the aim of the present study was to determine the relationship of positive and negative perfectionism with competitive state anxiety. 100 soccer players completed positive...

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...

It is a long time that the Simulated Annealing (SA) procedure is introduced as a model-free optimization for solving NP-hard problems. Improvements from the standard SA in the recent decade mostly concentrate on combining its original algorithm with some heuristic methods. These modifications are rarely happened to the initial condition selection methods from which the annealing schedules start...

liberal thinkers believe that one of the main features of liberal public philosophy is the liberal state neutrality among competing attitudes of happiness. hence, one of the liberal ideals is that state refrains to determine the public goods and guiding people towards a particular virtue and so state remains neutral among opposition and competing views in this regard. by studying the books and ...

by using a model of development, called developmental state, which appeared during the history of development in east asia region, the current essay tries to present a review on possibility of iran’s transition to economic development. it is supposed that the ground is prepared for iran’s transition to development through effective state intervention in economy. unlimited access of iran to a ve...

there are two different contradictory approach regarding the interaction of the state immunity and jus cogens. some jurist argue that jus cogens rules should prevail over other inconsistent ordinary rules of international law including state immunity. this argument therefore depends upon the existence of conflict between rules of jus cogens, and the rule of customary law which requires one stat...
