in this study, the spatial distribution of overwintered adults of sunn pest, eurygaster integriceps puton, was investigated by using dispersion parameters and indices, mathematical distribution, and regression techniques in rainfed wheat fields by sample size of 1 m2 in 2009 and 2010. the dispersion parameters including: mean-variance test and clumping parameter () showed that the overwintered ...

abstract: in this research, the relationship between geomorphologic factors with underground water resources in zahab plain (in west of kermanshah) has been analyzed using by analyzing-deducing and weighting methods. first, by using of pizometeric and exploratory well data, variation of water table in zahab plain has been comparative analysis with geomorphic unites and then, the zahab watershed...

groundwater quality regarding major anions and cations in the birjand plain located in the largest desert in eastern iran was monitored in this study. fifteen boreholes were considered as sampling stations and the parameters ph, tds, ec and major anions and cations were measured in groundwater samples. the dominant groundwater types can be introduced as sodium-chloride and magnesium-sulphate. t...

We present a concurrent higher-order programming language called Plain and a concomitant static type system. Plain is based on logic variables and computes with possibly partial data structures. The data structures of Plain are procedures, cells, and records. Plain’s type system features record-based subtyping, bounded existential polymorphism, and access modalities distinguishing between readi...

On occasion gastric ulcers may be recognized on plain abdominal radiographs. A case in which a gastric ulcer was diagnosed on the plain abdominal radiograph, illustrating the importance of careful scrutiny of the plain film in all cases of acute abdomen, is presented. The existence of the lesser curvature ulcer was confirmed on barium contrast studies.
