the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
Salinity problems reduce productivity on both irrigated and non-irrigated agricultural lands. Saline soils occur in arid semi-arid regions where rainfall is insufficient to meet the crops’ water requirements leach mineral salts out of root-zone. Compost can play an important role managing, mitigating, improving soil salinity negative effects. In this work, compost effects salt affected were stu...
Lotic freshwater ecosystems are among the most threatened worldwide due to effects of multiple stressors, such as intensive land use in their catchments, morphological alterations, flow regulation, pollution, and climate change. Odonata often used valuable indicators ecological integrity anthropogenic disturbance habitats. Here, we present results a study on assemblages anthropogenically impact...
The bauxitic-lateritic deposit at northeast of Malekan (East-Azarbaidjan Province, NW Iran) occurred as interlayer horizon within the Ruteh carbonate formation (Middle-Upper Permian). Based on compositional values of major elements, this deposit is divided into four discrete lithologic facies including, (1) laterite, (2) ferruginous bauxite, (3) bauxitic clay, and (4) siliceous bauxite. Petrogr...
Afforestation has been one of the most effective measures to compensate for mangrove ecosystem loss across the world and requires a detailed understanding of all contributing hydrological and physico-chemical factors affecting their growth. In this study, the Maxent habitat suitability model was employed to identify suitable mangrove habitats in the Hara Roud-e Gaz Protected Area. Presence da...
comparison of the effects of bran versus fresh vegetable on the metabolic and physico-chemical qualities of stool
Microscopical studies were carried out, in addition to physico-chemical and mineralogical analysis, in order to evaluate the effect of parent material and weathering on soil genesis in forest regions of Lahijan. Two representative soil pedons in mountain landform developed on granite and andesitic basalt located about 8 km southeast of Lahijan were selected and sampling were taken from each hor...
Manganese doped crystalline copper oxide (CuO:Mn) and undoped CuO were prepared at room temperature by the hydrothermal method. The complete physico-chemical characterization of materials was performed using X-ray diffraction (XRD), transmission/scanning electron microscopy (TEM/SEM), photoelectron spectroscopy (XPS). Furthermore, their analytical applicability tested in electrochemical experim...
all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...
the present study has been undertaken in a laboratory scale to characterize and investigate pollution potential of textile effluents from depz area in dhaka, bangladesh. collected effluent samples from five different industries were analyzed for physico-chemical parameters using field kits and standard methods, and for metals using flame atomic absorption spectrophotometer (faas). the average p...
