in this paper, river regime equations through developing of unit stream power equation and based on data of sistan and karaj rivers were derived. at the first step, methods and out-comes of former researchers are classified. on the next step, based on dimensional analysis, unit stream power as a function of river flow parameters including suspended sediment load and specific gravity of particle...

the internal infections of erwinia amylovora have important roles for disease beginning in the spring and dissemination of inoculum through infected vegetative planting material and nursery trees. in this study, we survey internal infection of erwinia amylovora in symptomless commercial apple cultivars in karaj and damavand cities, using optimized diagnostic methods such as plating on semi sele...

One of the problems of public health in Iran is mycotic inflection which its incidence is not known. The most important disease of them is dermatophytosis. In this regard, determination of various species of etiologic agent, infection source, the risk of contact to animals, and public training are necessary to perform epidemiologic studies. In this research 750 suspected samples (including 560 ...

The vegetation of Eshtehard salt marshes in Karaj was studied, using the Braun-Blanquet method. Sixty five relevés recorded in different salt habitats were analyzed by Analyse Factorielle des Correspondances (AFC) and Classification Ascendant Hierarchique (CAH) methods, using the Anaphyto software. In general, 11 plant associations determined in the area: Aeluropodetum littoralis, Artemisietum ...

Today, life is full of dominant changes. Interaction of individual characteristics with environment determines the adjustment and reactive responses. Economic and social changes are important factors that have influence on adolescence's life (1). Change in life has positive or negative effects. Negative changes in life lead to high risk behaviors and increase the risk of unsecure behaviors. Hig...

This paper introduces an improved convolutional neural network based on the conventional U-Net for simulating built-up land expansion. The proposed method hires a pixel-wise semantic segmentation approach considering spatial drivers affecting urbanization as data cubes. Independent variables including altitude, slope, and distance from barren, crop, greenery, roads, urban areas 1998, 2008, 2018...
