1-introduction languages employ different strategies to represent motion as one of the basic human cognitive abilities. in talmy's typological dichotomy (1991; 2000b) languages are of two types according to the way they represent path either in verb roots or in satellites, accordingly languages are either verb framed or satellite framed. slobin (1991;1996 a,b.1997;2000) performed corpus based a...

Being on the right pathThe 1st issue of the Iranian Journal of Radiation Research (IJRR) was published two years ago (June 2003). This journal was initiated to bring together the various disciplines of radiation oncology, radiation biology, medical physics, nuclear medicine and other related subjects to intensify the dialogue between basic and clinical researchers especially those working in Ir...

introduction: the aim of this in vitro study was to evaluate the effects of establishing glide path on the centering ability and preparation time of two single-file reciprocating systems in mesial root canals of mandibular molars. methods and materials: sixty extracted mandibular molars with curvatures of 25-39 degrees and separate foramina for the mesiobuccal and mesiolingual canals, were divi...

We provide several new algorithmic results for the secluded path problem, specifically approximation and optimality results for the static algorithm of [3, 5], and an extension (h-Memory) of it based on de Bruijn graphs, when applied to bounded degree graphs and some other special graph classes which can model wireless communication and line-of-sight settings. Our primary result is that h-Memor...
