The combined model approach uses kinetic analysis of both plasma insulin and C-peptide dynamics to estimate prehepatic insulin secretion rates and parameters of insulin and C-peptide kinetics. The original model used single-compartment kinetics to describe both insulin and C-peptide despite knowledge that C-peptide follows two-compartment kinetics. The performance of the model under rapidly cha...

a hydrophilic macromolecular network is prepared by performing graft copolymerization of poly (sodium acrylate) chains onto salep and silica gel. the reaction parameters affecting the water absorbency of the superabsorbent composite were optimized using taguchi method. ft-ir spectroscopy and thermo gravimetric analysis (tga) were used for confirming the structure of the final product and morpho...

In the present work, the drying of calcium carbonate in a batch spouted bed dryer with inert particles has been investigated experimentally. The effect of several operating parameters including air temperature (90, 100, and 110 ˚C), air velocity (Ums, 1.2 Ums, and 1.5 Ums), and dry solid mass (5, 10, 20 g) has been studied. The Taguchi method has been applied to determine the optimal parameters...

Background: Optimal thawing rate is critical for quality and fertilizability of frozen -thawed spermatozoa. Kinetic parameters are the most important factors which are affected by thawing rate so, that have close relation between kinetic parameters and fertility of the spermatozoa. Tris - egg yolk have been widely used for cryopreservation of the buffalo and other species semen. According to ou...

the photocatalytic degradation of betamethasone sodium phosphate was investigated in aqueoussuspensions of zinc oxide nanoparticular with diameter size 20 nm under a variety of conditions.different parameters such as irradiation time, the amount catalyst (0.12-0.8 g lh), initialconcentration of drug (10-50 mgljand initial ph values (ranging from 3 to ii) were investigatedin the presence of vari...

in this research, zeolite a was synthesized from waste porcelain and cds nano-particles were doped in zeolite framework by a precipitation after an ion exchanging process. all raw and modified samples were characterized by ft-ir, xrd and sem methods. primary experiments showed that the good efficiency of loaded nano cds onto the zeolite a for photodecomposition of dimethyldisulfide (dmds) under...

the objective of this study was to investigate the drying kinetics of oyster mushroom, pleurotus ostreatus mushrooms were dried using a cabinet-type convective dryer. air temperatures of 50, 60 and 70 oc were used for the drying experiments. the experimental drying data were fitted to different theoretical models to predict the drying kinetics. nonlinear regression analysis was performed to rel...

In order to respond to the basic requirements of food and pharmaceutical industries, to reduce or eliminate organic solvent residues in the final products, several extraction techniques were tested from the standpoint of performance, with low energy consumption. The aim of this study was to determine biological activities such as antioxidant and antiproliferative activities of flavonolignans fr...
