wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...

power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...

vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...

     Confectionery sunflower (Helianthus annuus L.) is one of the valuable crops which less is known about its variability. Fifty sunflower populations have been gathered from different regions of Iran and evaluated for agro-morphological traits in completely randomized design with 10 repetitions under pot conditions. The twenty traits including days from planting to flowering, days from planti...

Study of vegetation and environmental factors is considered as one of the important aspects in the management and conservation of natural ecosystems. This research investigates the effect of altitude from sea level (ASL) (in four classes: less than 1600 m, 1600-1800, 2000-1800 and more than 2000 m) and the direction of slope (in four main directions: north, south, east and west) on vegetative a...

Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
