the study was carried out in the ilam oak forest that is located in the west part of iran. the objective of this research was to determine the plant ecological groups and site classification in this region. data were collected from 117 sample plots using the systematic-random sampling method. the size of sampling plots was 20 m?20 m for the tree and shrub species and 1.5 m ?1.5 m for herbaceous...
Coastal wetland responses to sea-level rise are greatly influenced by biogeomorphic processes that affect wetland surface elevation. Small changes in elevation relative to sea level can lead to comparatively large changes in ecosystem structure, function, and stability. The surface elevation table-marker horizon (SET-MH) approach is being used globally to quantify the relative contributions of ...
recognition of habitats and conditions of species presences in differentsituations can be effective in proper utilization of vegetation. little is known about thevegetation composition of boralan mountain region located in north west of iran in theborder of turkey and azerbaijan with the altitude range of 800-2000m. the aim of thisstudy therefore was to investigate the floristic composition qua...
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...
UNLABELLED The architectonic subdivisions of the brain are believed to be functional modules, each processing parts of global functions. Previously, we showed that neurons in different regions operate in different firing regimes in monkeys. It is possible that firing regimes reflect differences in underlying information processing, and consequently the firing regimes in homologous regions acros...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
despite being the member of the international disarmament and non-proliferation conventions i.e. non-proliferation treaty (npt), chemical weapons convention (cwc) and biological weapons convention (bwc) which include their own specific export control regimes, some developed countries established parallel export control regimes that are against their commitments under aforementioned internationa...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
Predicted increases in the length of the growing season as a result of climate change may more frequently expose high-elevation plants to severe frosts. Understanding the ability of these species to resist frosts during the growing season is essential for predicting how species may respond to changes in temperature regimes. Here, we assessed the freezing resistance of 24 species from the centra...
