three species belonging to three genera of the family tylenchidae, namely, cephalenchus leptus, eutylenchus excretorius, and lelenchus leptosoma were discovered as first reports for iran's nematode fauna. they were characterized by morphological, morphometric and molecular phylogenetic studies. the two latter genera are new for iran. iranian population of cephalenchus leptus is characterized by...

six belonolaim species were collected from grasslands of sabalan region. the found species belong to genera amplimerlinius, merlinius, nagelus, neodolichorhynchus, paramerlinius and tylenchorhynchus. among the found species, neodolichorhynchus judithae is reported for the first time from iran and is characterized byhaving offset head, cuticule with 16 longitudinal ridges, delicate stylet 21-23 ...

The new genus Pedoniphis gen. nov. (Acari: Mesostigmata: Eviphididae) is described from soil detritus in Sabalan Mountains, northwest Iran, with P. persicus sp. nov. as type species. Among known eviphidid genera, the new genus is the most similar to Scamaphis Karg and Scarabacariphis Mašán and it can be distinguished especially by the dorsal chaetotaxy (setae J2 absent, setae J5 rudimentary) an...

condition of contour lines in topographic maps, explains more geomorphologic issues such as effective processes in the land forms found in nature. change in the curvature of the transverse profile of a valley in mountainous areas, the peak of the mountain range, also reflect the geomorphologic features and expresses the tectonic events and climate changes occurring in the region. these changes ...

Program comprehension is a necessary step for performing many software engineering tasks. Dynamic analysis is effective in producing execution traces that assist comprehension. Traces are rich sources of information regarding the behaviour of a program. However, it is challenging to gain insight from traces due to their overwhelming amount of data and complexity. We propose a generic technique ...

volcanic landform can be as terrain legacies from the past to the present era be considered. these heritage of land in terms of their unique characteristics can be considered as geomorphosite in the scientific community and the public. the evaluation of resources is one of the most important tasks of geotourism research.and thereby become profitable and thriving tourism industry in their own di...

in order to study on adaptability and grain yield stability of eight bread wheat cultivars (alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya), a rcbd experiment was conducted during three cropping seasons (2007-2010) at six locations (sanandaj, gorveh, marivan, divandarreh, saggez and baneh). simple analysis of variance (anova) and combined anova for three years in each locat...

this study was conducted to evaluate seasonal concentrations of macro-minerals in serum or plasma of sheep under grazing conditions to establish mineral deficiencies and excesses over a two-seasonal grazing period (fall-winter and spring-summer corresponding to the rainy and dry seasons) according to variations of year, region and animal classes in sabalan, iran. in each flock, ten sheep (38-50...
