There are reasons to consider quantum calculations be necessary for ion channels, two types of reasons. The must account charge transfer, and the possible switching hydrogen bonds, which very difficult with classical force fields. Without understanding transfer bonding in detail, channel cannot understood. Thus, although approximations correct fields possible, they unable reproduce at least som...

that run on one leg. The generalization uf these one-leg algorithms for control of machines with several legs is explored. The generalization is quite simple when multilegged systems run with gaits that use the support legs one at a time. For these gaits the ~ n e-l e g algorithms can be used b o control multilegged running. The cortcept of a virtual leg is introduced to further extend the appr...

While the advantages of cooperative learning activities have been extensively acknowledged in L2 literature, this type of pedagogy has not received due attention in the Iranian EFL context. Indeed, the traditional reading method still dominates in most Iranian EFL university classes even though it fails to meet its main objective which is training competent EFL readers. In an attempt to address...

Users’ problems in developing applications rarely factor easily so as match the solutions provided by the Knowledge Representation community. If KR is to be applied successfully, the gap between users’ “problem space” and the KR “solution space” must be addressed. Two approaches are suggested: “Intermediate representations” at a higher level of abstraction than current KR languages and a set of...

Leaflets inside pharmaceutical packages should include focal points about medicines being used by patients. The current study was designed to assess the compliance of information cited in herbal medicine leaflets with the standards released by the Ministry of Health and Medical Education of Iran (MHMEI). Leaflets of commonly used herbal pharmaceutical products sold in pharmacies of Iran were co...
