electrical sensitivity of a beryllium oxide nanotube (beont) was examined toward (c4h5n) molecule by using density functional theory (dft) calculations at the b3lyp/6-31(d) level, and it was found that the adsorption energy (ead) of pyrrole on the pristine nanotubes is a bout -48.58kcal/mol. but when nanotubes has been doped with s and p atomes , the adsorption energy changed. calculation sho...
electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...
in this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-ca) to convert carbon dioxide to bicarbonate ion. density functional theory (dft) using b3lyp and ub3lyp functional and three split-valance including 6-31g*, 6-311g** and 6-311++g** basis sets were used to calculate the details of electronic structure and electronic energy of act...
inhibitory effect of three benzothiazole derivatives (1, 3-benzothiazol-2-amine (bta), 6-methyl-1, 3-benzothiazol-2-amine (mbta) and 2-amino-1, 3-benzothiazole-6-thiol (tbta)) on corrosion of carbon steel has been studied using density functional theory (dft) method in gas and aqueous phases. quantum chemical parameters such as ehomo (highest occupied molecular orbital energy), elumo (lowest un...
in order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. to do this we have investigated optical waveguide both with and without optical pumping. the rate of absorption and emission using an array of algaas/gaas quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. by con...
In a completely randomized design (CRD) experiment with 6 treatments and 4 replicates per treatment, the effect of energy and protein dilution during 6-12 days of age was tested in broilers. Rice hull was used for dilution of energy and protein at levels of 0.05 (control), 10, 15, 20, 25 and 30 percent. The metabolizable energy and crude protein content of the experimental diets were 3089, 2780...

this experiment was conducted to evaluate the effect of vitamin premix withdrawal from diets containing different energy levels on growth performance and carcass characteristics of broilers subjected to heat stress in a completely randomized design with 2×3 factorial arrangement containing, 2 levels of energy (low and high energy) and 3 levels of vitamin premix withdrawal (28, 35 and 42 days). ...
Background and aims: In automated excavation operations especially excavating big tunnels with high operation speed the application of Tunnel Boring Machine (TBM) has been prevalent. Tunneling construction projects especially TBM excavating operations have experienced some accidents in recent years. Hazard control must be done through the process of risk management. This study was done w it...
in this work, theoretical investigations on carbon nanotube with oxygen atom have been carried out by firstprinciplescalculations and density functional theory and hartree fock theory in 3-216 and 6-316 basis sets. theinteraction energy of the oxygen atom to a cnt is calculated. the effects of this substitutions have beeninvestigated on the during transplantation (10,0) single-walled carbon nan...
