sediment core samples can provide useful information about aquatic environment. sedimentation rate, climate changes and heavy metal concentration are among the most important studies that are carried out on sediment cores. in this study, a sediment core of 70cm with aim of metal concentration investigation is collected from central part of the zarivar lake in the vicinity of the marivan city in...

four genera and five species of idolothripinae are recorded in iran: allothrips hood, compsothrips reuter and pseudocryptothrips priesner each with one species, and megathrips targioni-tozzetti with 2 species. in this paper, the genus nesothrips kirkaldy, with one species n. brevicollis (bagnall) collected on grasses in marivan, kurdistan province, is recorded in iran for the first time. a key ...

zarivar lake is the only natural water area and the ponds in the kurdistan province which is located 2 kilometers far from the northwest of marivan city and at an altitude of 1285 meters above sea level. the mean annual rainfall is 997.6 mm and the mean annual temperature is 13°c. this study is carried out to survey the biodiversity, identification and introduce plant species around the lake an...

the intention of this paper is to define the concept of the spirit of place, and then to identify methods for its preservation in historical urban contexts. in fact, this study seeks to answer the question whether the spirit of the place and its components can be derived from tissue structure to improve? and whether we can weave his old identity in psychological indicators - human behavior foun...

It is shown that the quantization of a superparticle propagating in an N = 1, D = 4 superspace extended with tensorial coordinates results in an infinite tower of massless spin states satisfying the Vasiliev unfolded equations for higher spin fields in flat and AdS4 N = 1 superspace. The tensorial extension of the AdS4 superspace is proved to be a supergroup manifold OSp (1|4). The model is man...
