Introduction: In this study, a specific combination (70% W 18.61% Ni and 11.39% C) of lead free and flexible putty metal is introduced and validated as internal shielding by Mont Carlo study Materials and Methods: To evaluate putty metal as an internal shielding by Mont Carlo study Varian 2100 C/D was validated within measurement and then by given energy spect...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
The response of twenty acid-sensitive headwater catchments in Nova Scotia to acidic deposition was investigated for the period 1850–2100 using a dynamic hydrochemical model (MAGIC: Model of Acidification of Groundwater in Catchments). To ensure robust model simulation, MAGIC was calibrated to the long-term chemical trend in annual 5 lake observations (13–20 years). Model simulations indicated t...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Chemical fertilizers have important role in modern agriculture, and in the other hand led to rigid environmental pollution. Urea fertilizer is one of the most widely used and least expensive nitrogen fertilizers in Iran. Since it is high solubility in water a significant of it, if irrigation or precipitation is heavy, easily washed and led to change to change the quality of groundwater, rivers ...
A study of the time evolution of GERB shortwave calibration by comparison with CERES Edition-3A data
Article history: Received 14 January 2016 Received in revised form 8 August 2016 Accepted 7 September 2016 Available online xxxx This study examines the evolution of the GERB-2 and GERB-1 Edition 1 shortwave radiance calibration between 2004–2007 and 2007–2012 respectively, through comparisonwith CERES instrument FM1Edition 3A SSF instantaneous radiances. Two periods when simultaneous observati...
Background: The association of duration of breastfeeding (BF) with weight disorders remains controversial. This study aimed to evaluate the association of BF with anthropometric measures and weight disorders in Iranian children and adolescents. Materials and Methods: Using multistage random cluster sampling method, a representative sample of 25,000 school students were selected from urban an...
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
