in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
in this research we have developed a treatment method for textile wastewater by tio2/sio2-based magnetic nanocomposite. textile wastewater includes a large variety of dyes and chemicals and needs treatments. this manuscript presents a facile method for removing dyes from the textile wastewater by using tio2/sio2-based nanocomposite (fe3o4@sio2/tio2) under uv irradiation. this magnetic nanocompo...
The first objective of the paper is to expose the Green Information Systems (Green IS) management framework comprising the enabling capabilities of Green IS, moderating concepts, and relationships to environmental sustainability. The second objective is to demonstrate the framework’s verification using the focus group method and member checking. The achievement of these objectives establishes t...
Two widely used affected-sib-pair scoring procedures (the Green and Woodrow [1977] procedure, and the method of forming all possible affected-sib-pairs) are compared with a new method for their relative efficiency in detecting the presence of an HLA-linked disease susceptibility gene. Their relative performance is investigated by extensive computer simulations over a large number of disease tra...
Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...
Identifying and developing green jobs in the agricultural and rangeland areas can revitalize the rural economy and the environment. Green jobs are considered by policy makers as the main solution to the global crisis in the current economy and environment, and the move towards a more sustainable economy and a society that maintains the environment of current and future generations. The present ...
The present study was carried out aimed to investigate the role of self efficacy and social tendencies in green purchase intention and behavior. This study is considered as an applied research in terms of purpose and descriptive-survey research in terms of data collection method. In this study, the statistical population includes all consumers of organic products supplied at Ofogh Koorosh chain...
background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...
In this paper, the meshless integral method based on the regularized boundary integral equation [1] has been extended to analyze the large deformation of elastoplastic materials. The updated Lagrangian governing integral equation is obtained from the weak form of elastoplasticity based on Green-Naghdi’s theory over a local sub-domain, and the moving least-squares approximation is used for meshl...
A high performance liquid chromatography (HPLC) system for pigment analysis of marine phytoplankton was established. The characteristic quantification limits of the major photosynthetic chlorophylls a and b were 0.29 and 0.27 ng, respectively. The reliability of this method was verified by resolving the marker pigments in culture extracts from diatoms, blue-green algae and green algae. Fucoxant...
