We consider how a persistent programming language might offer performance competitive with that of non-persistent languages, at least on memory resident data. We are concerned with object-oriented languages, and with implementing persistence via object faulting, where the system detects uses of non-resident objects and fetches them on demand. We present some background on object faulting and me...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...
