a new correlation function for the calculation of viscosity for five typical supercritical gases is presented using the rainwater-friend and modified enskog theory. it is shown that by using accurate value for the thermal pressure and co-volume in the modified enskog theory, this correlation function is suitable for calculation of the viscosity of supercritical gases, without any density and te...

Heme oxygenases (HOs) catalyze the oxidation of heme to biliverdin, carbon monoxide (CO), and free iron. Iron acquisition is critical for invading microorganisms to enable survival and growth. Here we report the crystal structure of ChuS, which displays a previously uncharacterized fold and is unique compared with other characterized HOs. Despite only 19% sequence identity between the N- and C-...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

one of the most valid and efficient models of long rod projectile penetration in homogeneous targets is tate and alekseevskii’s (a&t;) model. based on tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. the proposed collision speed-penetration depth diagrams are developed using tate’s model. in this way, v...

plotinus' attempt to counter the aristotle critiques on plato's theory of ideas, leads to his theory of emanation, which is called double act doctrine. plotinus is influenced by aristotle, not only in raising the problem of emanation quality, but the language and terms (including reasonable matter, indefinite dyad and activity) that are used to describe his theory. also, the theory of...

allame tabatabaei believes that theory of fitrah (instinct qualities of human nature) rests upon the principle of general instinct conductance of creatures and considers this theory as a branch of it. he also believes in the theory of eternal inherent happiness and unhappiness of human being, explains it in a way that it can be compatible with the benevolent tendency in every human being’s natu...

Pulvermüller (2014) and Moro (2014a,b) exchange views on the possible relation between syntax and action. Pulvermüller points out that human’s action displays hierarchical and embedding properties, analogous to how a sentence is organized by the human mind. His claim is that syntax may not be as sui generis as syntacticians upheld. As more evidence reveals the neurobiological mechanisms underly...

abstract the traditional or liberal theory of contract always had encounter serious critics. the authors of this article have criticized this theory- based on new theory of unger (a pioneer in the critical legal studies movement) - and also have analyzed the strengths and weaknesses of that. this theory consists of a principle and a counter principle that include freedom of contract against the...

theory is a base for all scientific disciplines. theorizing is an important branch in architecture too. there are a little reference that tries to define theory and show the differences between theory in architecture and theory in other disciplines. this article aimed to show the characteristics of architectural theory. at first we try to review different books and articles which are written on...
