gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
phytochemical constituents, such as total phenol, allicin and pyrovic acid as well as antioxidant activity of thirteen ecotypes of allium hirtifolium boiss. from different regions of iran were evaluated. average contents of total phenol, allicin and pyrovic acid of bulbs extracts per g fresh weight were 0.647 mg gallic acid equivalent (gae), 2.127 mg and 84.412 µmol, respectively and antioxidan...
Aeluropus littoralis is one the most successful monocot grasses in terms of high salinity tolerance, that contains forage quality and has valuable physiological features. The goal of this study is to introduce and provide quick access to DNA-based molecular markers for valuable halophyte, Aeluropus littoralis to assessment of genetic diversity. For this, a total number of 110 EST-SSR ma...
three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
cml in breif cml is characterized by the proliferation of large numbers of immature wbc in the blood and bone marrow. in most of the patients , it is a clonal disorder in which all cell lines, express the philadelphia chromosome)q/22 translocation(it accounts for 20 of all leukemias and most cases occur over 25 yrs of age. the disease usually begins insidiously,but symptoms referable to anemia ...
Studying genetic diversity is important because a decrease in genetic variability might result in a reduction of the plasticity of the crops to respond to changes in climate, pathogen populations, or agricultural practices. In this study, 72 Sardari wheat (Triticum aestivum L.) ecotypes were analyzed by AFLP markers and 17 phenotypic characters. Three pairs of EcoRI/MseI primer combinations pro...
The evolution of reproductive isolation in the presence of gene flow is supported by theoretical models but rarely by data. Empirical support might be gained from studies of parallel hybrid zones between interbreeding taxa. We analysed gene flow over two hybrid zones separating ecotypes of Littorina saxatilis to test the expectation that neutral genetic markers will show site-specific differenc...
in order to investigate the responses of sardari wheat ecotypes to drought stress, 12 spikes of sardari wheat were selected from different regions of kurdistan province and planted as head to row. in the second year, a split- plot factorial field experiment was conducted. in this experiment water stress and irrigation were considered as the levels of main factor and 12 sardari wheat ecotypes al...
Coevolution is one of the major processes organizing the earth's biodiversity, but it remains unclear when and how it may generate species diversity. The study by Parchman et al. () in this issue of Molecular Ecology provides the clearest evidence to date that divergent local adaptation in a coevolving interaction may lead to speciation on one side of an interaction but not necessarily on the o...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
