One of the biggest motivations behind the development of the metal matrix composites (MMCs) is the improvement of the mechanical wear resistance of the unreinforced metallic matrix material mainly by the load-bearing effect of the hard reinforcement phases. However, in a large number of applications, MMCs are also required to operate in intimate contact with aqueous environments, which may lead...

We report on the first thermodynamical investigation of (TMTTF)2Br in its antiferromagnetic ground state. There is a discontinuity in the lattice specific heat, Cp/T~,

Project courses provide students with a hands-on experience of software engineering practices in industry and prepare them for their later career. The first weeks of such a course typically involve change and uncertainty and are therefore challenging for students: project teams have to understand requirements that are often unclear, learn to work together and communicate as a team, as well as b...

state as most affecting organization in politics, effects on different sphere in social life. in development discussion and its strategies, we must attention to these subjects: how can state effects on development? what is its role in this respect? some researches have historical attributions and study the role of state in development countries in past. other researchers, study the role of stat...

after the iranian mashrooté revolution, the shiite political thought faced a new era of much attention, contemplation and explanation, when religious scholars embarked on a new research project to address the new situation. the most serious attempt to deal with the theoretical gap and crisis in islamic state was contributed by imam khomaini. in his theory of state, he conjoined the shiite princ...

background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, es­pecially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...

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...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...
