Research on the special relationship between the United States and Israel hasusually been focused on strategic aspects, whilst fewer scholars have focusedon non-material dimensions of the relationship. In addition, the existingresearch is mostly confined to the political and decision-making realms, withvery few excursions into the academic arena. The current article aims...
First Principles Modeling Studies of Field Evaporation:Preliminary Studies Relevant to the Atomscope
although the promotional effects on bone healing of pulsed electromagnetic fields (pemf) have beenwell demonstrated, the effects of static magnetic fields (smf) remained unclear. in this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. after an osteotomy of the midshaft radius...
background: in the recent years, eutrophication has become a serious challenge for many of the water ecosystems. it has affected the environmental and economical aspects of the anzali wetland, which is known as one of the significant ecosystem. due to the increase of the nutrient loadings from the industrial, agricultural and human activities, the wetland’s health is faced many serious problems...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
a series of ddt irritability tests with adult a. maculipennis typicus and a. superpictus were carried out in the isfahan area in august-september, 1970. the observations on irritability were measured in accordance with the who method arid the natural populations of anopheline mosquitoes were used. the tests were carried out in a light intensity of approximately 8 foot candles. the engorged mosq...
Surface roughness represents the measure of irregularities on surface contributing to local field enhancement. The traditional Fowler-Nordheim equation established for perfectly planar surfaces is not suitable describing emission from rough surfaces. Instead, it more appropriate use that accounts enhancement factor effect morphology. In superconducting radio frequency cavities, may occur in iri...
