this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
Due to the ongoing remote control in signalling technology train observation by employees is reduced at traditional locations e.g. place of a station manager. The Austrian Federal Railways (ÖBB) Infrastructure Operation Company has recognised this trend very early. Several years ago, they started the construction of a wayside detection system to control the temperature of passing trains because...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
Iranchr('39')s location on the arid world belt, the occurrence of climate change and global warming and the increased in human interference have resulted in dust storms phenomenon in the western and southwestern parts of the country, especially in Khuzestan province. The present study has been aimed at investigating the existing water resources of the province for the watering operation of the ...
The effect of Urban Development on Watershed Hydrological Properties (case study: Tajrish Watershed)
The effect of Urban Development on Watershed Hydrological Properties (case study: Tajrish Watershed) Throughout the human history, societies and rivers have been closely linked, so that the human civilization began from the riverside (Stevaux et al. 2009 (. The quantitative and qualitative characteristic of river is vulnerable to land-use changes (Kang et al. 2010). Natural and urban watershed...
rainfall and flow rate are of the most important climatic and hydrologic parameters whose investigation and determination of their behavior are of great importance in water resources management. one of the most suitable methods available for assessment of hydro-climatological conditions in the watershed is trend analysis which is used to examine the changes of a variable during time. current st...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
todays, the world development is facing serious water quality issues. since protect of water quality and ecosystem healthy is an important aspect of ecohydrology. the present research aimed to analyze the temporal trends of water quality parameters of mashin zard river station in order to planning long term management approaches. in this research, trend of some significant factors of water qual...
