Of the applications of remote sensing and satellite images in natural resources is distinguishing and detection of changes in land surface. The image classification using Maximum Likelihood (MLC) is one the prevalent method which is used in a study of the application of TM and ETM+ satellite images to detect sediment deposition on an implemented floodwater spreading scheme. In order to implemen...
Deposition and re-entrainment of 1.1 microm microspheres were examined in packed glass beads and quartz sand under both favorable and unfavorable conditions for deposition. Experiments were performed at environmentally relevant ionic strengths and flow rates in the absence of solution chemistry and flow perturbations. Numerical simulations of experimental data were performed using kinetic rate ...
We estimate the global risk from the release and atmospheric dispersion of radionuclides from nuclear power plant accidents using the EMAC atmospheric chemistry– general circulation model. We included all nuclear reactors that are currently operational, under construction and planned or proposed. We implemented constant continuous emissions from each location in the model and simulated atmosphe...
in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...
In this work, NiCu and CoCu alloy nanowires were prepared by electrodeposition within nuclear track-etched polycarbonate membranes with the nominal diameter of 30nm. Electrodeposition was carried out under potentiostatic control with three electrodes. In order to grow CoCu nanowires and NiCu nanowires, an electrolyte containing salts of Co and Cu, and an electrolyte containing the salts of Ni...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
Background: Periodontal ligament stem cells (PDLSCs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. Materials and Methods: This study examined the effects of dexamethasone (Dex) on human PDLSCs in vitro. PDLSCs obtained from the roots of patient’s teeth were cultured with Dex (0....
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
