A mitochondrial fraction prepared from calf brain cortex possessed negligible glycolytic activity in the absence of the enzymes of the high speed supernatant fraction. When mitochondria were added to a supernatant system supplemented with optimal amounts of crystalline hexokinase, a 20 per cent stimulation of glycolysis was observed. The supernatant fraction produced minimal amounts of lactate ...

A precise experimental method for studying binary vapor-liquid equilibrium is to measure total pressure (P) as a function of the mole fraction in the liquid phase (2). The mole fraction in the vapor (y) is calculated from imthermal P-x experimental data using the Gibbs-Duhem equation. A similar procedure for adsorption is to measure total mass (m) of gas adsorbed as a function of the mole fract...

The structures of laminar premixed flames methane air mixture are investigated for different equivalence ratios and mass flow rates numerically. Chemkin 19 program GRI-Mech 3.0 mechanism is used numerical solution. axial velocity mole fractions each runs. It found that with the increase rate; velocities flame, location reaction zones fraction values intermediates increases. reactants do not cha...

In this study, the thermal performance of an internal heat exchanger-organic flash cycle system driven by geothermal water was investigated. The R600a/R601a mixtures were selected as working fluid. effects mole fraction on absorption capacity heater, temperature rise cold fluid in exchanger, net power output, efficiency, and electricity generation costs analyzed. outputs, costs, efficiency simp...

A novel glycopeptide (Cs-GP1) with an average molecular weight (Mw) of 6.0 kDa was isolated and purified by column chromatography from the lower Mw fraction of exopolysaccharide (EPS) produced by a medicinal fungus Cordyceps sinensis Cs-HK1. Its carbohydrate moiety was mainly composed of glucose and mannose at 3.2:1.0 mole ratio, indicating an O-linked glycopeptide. The peptide chain contained ...

This research was conducted to determine the effect of CaCO3 levels on formation superconducting phase BPSCCO - 2212 by calculating level purity phases formed and looking at microstructure. The variation 0.95, 1.00, 1.05 1.10 mole using wet mixing method. samples were calcined 800 ° C for 10 hours, sintered 820 20 hours. Synthesized characterized X-Ray Diffraction (XRD) Scanning Electron Micros...

The incorporation of isotopic ethylene-C1Mmino-s-triazine (TEM), Myleran, chlorambucil, and sulfur mustard into the DNA fraction of regenerating liver and of various mouse ascites lymphomas was measured. The in vivo incorporation of these alkylating agents was estimated to be of the order of 1 mole of drug per mole of DNA polymer. Results obtained by several different methods of isolation of DN...

The work is devoted to the study of granulometric composition soils 120-year and 240-year agricultural development meadow-steppe landscape on example Belgorod region. In lateral distribution silt fraction contained in arable horizon, a significant increase its proportion lower parts soil catenas arable, for variations are less noticeable. averaged values content over slope profiles land showed ...

Gold-silver alloy nanoparticles with varying mole fractions are prepared in aqueous solution by the coreduction of chlorauric acid HAuCl4 and silver nitrate AgNO3 with sodium citrate. As the optical absorption spectra of their solutions show only one plasmon absorption it is concluded that mixing of gold and silver leads to a homogeneous formation of alloy nanoparticles. The maximum of the plas...
