original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

objective: cone beam computed tomography (cbct) is applied for the imaging of the maxillofacial and dental structures, particularly for surgical treatments and dental implants. the aim of this study was to assess the effect of slice thickness on the accuracy of cbct linear measurements. methods: in this diagnostic accuracy study, forty-two titanium pins with the same dimensions were inserted in...

conclusions this study indicated that the delivery rate accuracy of elastomeric infusion pumps is preserved after repeated usage. these laboratory findings suggested that elastomeric pumps could be safely refilled in the successive days to provide postoperative analgesia. results the mean flow rate in the three series of measurements showed a gradual increase; however, the difference was not st...

this article describes a knowledge management (km) success model that is derived from observations generated through an empirical study of km in an iranian consultant company and km success factors in the literature which is shown that company has a weak situation in each factor. so company needs a measurement model in order to assess knowledge management implementation processes in each step t...

understanding the opinions of major role players in education (i.e. teachers, students, and policy makers) on all aspects of learning and teaching is influential to the success of the educational process. the purpose of this study was to investigate efl (english as a foreign language) teachers' views on measuring reading comprehension. a cohort of 50 iranian efl teachers teaching at university,...

this paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. the purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. we have employed a multi-method approach which combines a “qualit...

control and evaluation are major secrets of an organization's survival.universities, as research and educational organizations, need to be evaluated in order to survive. the results of educational activities encompass a vast spectrum including the graduates, researchers and planners, scientific publications, as well as satisfaction of students, parents, profossors and staff (ramsden, 1996).th...

in this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. the electrochemical properties of the produced electrode are studied using cyclic voltammetry (cv) and electrochemical impedance spectroscopy (eis) techniques in 3m nacl, naoh, and koh electrolytes. scanning electron microscopy (sem) is used to characterize the mi...

studies investigating fertility decline in developing countries often adopt measures of determinants of fertility behavior developed based on observations from developed countries, without adapting them to the realities of the study setting. as a result, their findings are usually invalid, anomalous or statistically non-significant. this commentary draws on the research article by moeeni and co...
