In thisresearch, the formed reaction derivative of matter [b-5,1] Tetrazolo [4,2,1] Teriazine (TTA) with boron nitride cage Nano-structure was studied in different temperature conditions by DFT method. For this purpose, first, the materials on both sides of the reaction were the geometric optimization, then, calculation related to the thermodynamic parameters were done on all them. Then, the va...

Genomic DNA is constantly subjected to various mechanical stresses arising from its biological functions and cell packaging. If the local mechanical properties of DNA change under torsional and tensional stress, the activity of DNA-modifying proteins and transcription factors can be affected and regulated allosterically. To check this possibility, appropriate steady forces and torques were appl...

sawdust which is the main waste from wood industry has been used as a raw material forremoval of brilliant cresyl blue toxic dye. the effects of various parameters such as ph,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg l-1. the optimum condition for the studiedparameters was applied for various con...

 In this article, synthesis of the explosive 2, 6 (diamino) 3, 5 dinitro pyridine (ANPY) of the direct nitration reaction of 2, 6 diamino pyridine in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the the...

The photometric and spectroscopic data for three double-lined detached eclipsing binaries were collected from the spectral surveys. light radial velocity curves of each binary system simultaneously analyzed by using Wilson-Devinney (WD) code, absolute physical orbital parameters these derived. masses both components ASASSN-V J063123.82+192341.9 found to be $M_1 = 1.088 \pm 0.016$ $M_2 0.883 0.0...
