As one of the recipients 2019 Nobel Prize in Chemistry, John B. Goodenough has made significant contributions across chemistry and physics including development critical cathode materials for lithium-ion batteries, understanding d-electron behavior transition-metal oxides, transport properties perovskites. In article number 2000773, Karim Zaghib co-workers review some his scientific work demons...

Since the beginning of forties twentieth century, names some Kurdish personalities began to appear, They played their leading role in political movement, Karim Ahmed was one these figures, he had an active developing relations between parties within framework National Front.

The emergence of virtual community facilitates people with common interest/practices or shared experiences to communicate openly and broadly over the Internet. However, the problem of member contribution of original information and feedback has often been raised in the research of virtual community. Drawing on the perspective of competitive altruism, we argued that an altruistic individual memb...

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid-base equilibrium. We concentrate on the adsorption of hexahistidine, one of the most widely used tags in bio-related systems, particularly...

majd al-islam kermani was an intellectual clergyman and outstanding journalist of constitution period who spent his life on serving his country. he fought qajar despotic government, writing several articles in newspapers especially adab, even to be exiled to kalat. but after the constitutionalists got victory and the new government established, he published four newspapers in the name of nedaye...

In many animal species, learning and memory have been found to play important roles in regulating intra- and interspecific behavioral interactions in varying environments. In such contexts, aggression is commonly used to obtain desired resources. Previous defeats or victories during aggressive interactions have been shown to influence the outcome of later contests, revealing loser and winner ef...

The polar flagellum of Vibrio alginolyticus is rotated by the sodium motor. The stator unit of the sodium motor consists of four different proteins: PomA, PomB, MotX and MotY. MotX and MotY, which are unique components of the sodium motor, form the T-ring structure attached to the LP ring in the periplasmic space. MotY has a putative peptidoglycan-binding motif in its C-terminal region and MotX...
