the history of five thousand years of human civilization (with only 292 years with no war) and the experiencesof the past two decades of our country shows that the enemies’ approach is based on strong air attack just inthe first month, and civilians bombarding begins if the spirit of national defense continues after two weeks.so the buildings in the cities are damaged in different ways by the a...

BACKGROUND The procedure for making impressions of multiple implants continues to be a challenge, despite the various techniques proposed to date. The authors' objective in this case report is to describe a novel digital impression method for multiple implants involving the use of stereophotogrammetric technology. CASE DESCRIPTION The authors present three cases of patients who had multiple i...

Are the fastest running speeds achieved using the simple-spring stance mechanics predicted by the classic spring-mass model? We hypothesized that a passive, linear-spring model would not account for the running mechanics that maximize ground force application and speed. We tested this hypothesis by comparing patterns of ground force application across athletic specialization (competitive sprint...

this paper is an attempt to explore the prepositions used to encode the agent in persian passive constructions. according to givón (1983) the main function of the passive constructions is to defocus the agent. as the general trend in persian is to omit this defocused agent, we will stylistically divide the passive constructions into two main sub branches, namely unmarked and marked passives acc...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...

this paper studies the effect of flexible linear torso on the dynamics of passive quadruped bounding. a reduced-order passive and conservative model with linear flexible torso and springy legs is introduced. the model features extensive spine deformation during high-speed bounding, resembling those observed in a cheetah. fixed points corresponding to cyclic bounding motions are found and calcul...
