Multi-walled carbon nanotubes (CNTs) are synthesized with the assistance of water vapor in a horizontal reactor using methane over Co-Mo/MgO catalyst through chemical vapor deposition method. The application of Adaptive Neuro-Fuzzy Inference System (ANFIS) technique for modeling the effect of important parameters (i.e. temperature, reaction time and amount of H2O vapor) on the qualit...

The addition of co-solutes to colloidal suspensions is often employed induce tunable depletion interactions. In this work we investigate effective interactions arising from binary co-solute mixtures hard spheres and patchy particles. By changing the relative concentration two species, show that resulting potential $V_\text{eff}$ continuously changes one obtained for a single-component sphere me...

In this study, the effect of chamomile extract on the ability of neonatal calves to absorb immunoglobulin G (IgG) was evaluated. An ethanolic extract of chamomile was obtained with the concentration of 111 mg/ml. Calves were randomly divided into four groups, each receiving one of four chamomile treatments; 1: low dose (LC; 5.5 mg/kg body weight; 2: moderate dose (MC; 11 mg/kg); 3: high dose (H...

In this study, NiFe2O4 nanoparticles (NiFe2O4 NPs) were prepared through co-precipitation method and subsequently used for the removal of Co(II) ions from aqueous solutions. The NiFe2O4 NPs were characterized by transmission electron microscopy (TEM), X-ray diffraction spectrometry (XRD), and Brunauer-Emmett-Teller (BET) surface area analysis. In batch tests, the effects of variables such as pH...

concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...

solid lipid nanoparticles of atovaquone (atq-sln) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and compritol 888 ato as the lipidmatrices and phospholipon 90h, tween 80, and poloxamer 188 as the surfactants. optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...

Much attention is focused today on predicting how plants will respond to anticipated changes in atmospheric composition and climate, and in particular to increases in CO(2) concentration. Here we review the long-term global fluctuations in atmospheric CO(2) concentration as a framework for understanding how current trends in atmospheric CO(2) concentration fit into a selective, evolutionary con...

Caspian kutum fish (Rutilus frisii) wild broodstocks were caught by gillnet during their upstream migration and subjected to short-time confinement stress and their physiological responses have been examined. Thirty fish (average weight of 1217.6 g) were divided into three experimental groups CO (control), OV (ovaprim) and CO+OV (cortisol+ovaprim) and placed into rearing tanks (10 fish tank-1; ...
