the quality of surface water within a region is mainly influenced by natural processes such as precipitation, soil erosion and weathering, geology, vegetation and anthropogenic activities. the most important factor is geological formation in watershed and water flow path. in this study, the spatial variations of physical and chemical parameters of surface water including ec, sar, cl and tds and...

BACKGROUND In several Iranian provinces, there are large numbers of landmines that threaten the lives of many civilians. Ilam is one of the most polluted areas with 1,086 injuries from landmines between 1989 to 1999, with an overall mortality rate of 36.4%. A remarkable number of deaths occurred before the injured were conveyed to the hospital. In this survey, the effects of on trauma outcome o...

permeability is a property of porous medium that quantifies rock capacity to transmit fluids. frequently, core based permeability data are not available either because of the borehole conditions or due to the high cost of coring. for these reasons, over the years attempts have been made to estimate permeability by alternative ways. permeability is an elusive parameter in hydrocarbon reservoirs ...

AIM The aim of this study was to investigate the prevalence of human and animal fascioliasis in Ilam Province, Iran. BACKGROUND Fascioliasis, caused by Fasciola hepatica, is one of the most important zoonotic diseases. Snails are an intermediate host. Human infection with the parasite can led to hypertrophy and hyperplasia in bile duct. It also economic importance and further information is e...

Methods: This study is descriptive and retrospective and the sampling was carried out amongst the cases of patients who were hospitalized and operated...

This paper is concerned with information structures used in rigid formations of autonomous agents that have leaderfollower architecture. The focus of this paper is on sensor/network topologies to secure control of rigidity. We extend our previous approach for formations with symmetric neighbor relations to include formations with leader-follower architecture. Necessary and sufficient conditions...

Formations of multi-agent systems, such as satellites and aircraft, require that individual agents satisfy their kinematic equations while constantly maintaining inter-agent constraints. In this paper, we develop a systematic framework for studying formations of multiagent systems. In particular, we consider undirected formations for centralized formations and directed formations for decentrali...
