Neutron response Induced in Thermoluminescence Dosimeter TLD-700 chips due to reactions of thermal neutrons with slab phantom and Badge Dosimeter TLD-600,700 materials in a neutron-gamma mixed field was measured. Using the linear relationship between thermal neutron fluence and the thermal neutrons induced TL response with slab phantom, Badge-TLD Materials, an empirical relationship was introdu...
Abstract This study goes beyond the the prevailing use of averaged data to investigate the hidden evidence of asymmetry due to the effect of monthly exchange rate fluctuations on Iran's quarterly GDP during the period 1380:1-1397-4. For this purpose, the regression model of Mixed Data with different asymmetric frequency (MIDAS model) is use, which allows time series variables with different fre...
mixed layer is a part of the atmospheric boundary layer in which pollutants are uniformly distributed. it is sensitive to the earth’s surface, controls the flow of heat and momentum between the surface and the free atmosphere, thus playing a key role in atmospheric circulation. most of atmospheric pollution models require the height of the mixed layer as an input to determine the depth of atmos...
the present study was carried out to evaluate radiation absorption and use efficiency (rue) in replacement series intercropping of chickpea and sesame. the experiment included main factor a (planting methods) with two levels a1 (row planting) and a2 (mixed planting) and factor b (replacement planting pattern) consisting of five levels b1 (chickpea monoculture), b2 (75% chickpea+25% sesame), b3 ...
Background and Objectives: Different governance approaches have various definitions and systems about health. The purpose of this study was to compare the appropriateness of the health system performance with the ideology of the selected countries. Methods: In this comparative study, liberal countries (America, Canada, France), social countries (Russia, China, Cuba) and mixed countries (Sweden...
One of the common approaches for improving the reliability of a specific system is to use parallel redundant components in subsystems. This approach, which is known as the redundancy allocation problem (RAP), includes the simultaneous selection of the component type and its level for each subsystem in order to maximize the system reliability.Traditionally, there are two redundancy strategies, n...
the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
