This study tests the hypothesis that the metabolic and endocrine shift characterizing the phase II-phase III transition during prolonged fasting is related to a decrease in fatty acid (FA) oxidation. Changes in plasma concentrations of various metabolites and hormones and in lipolytic fluxes, as determined by continuous infusion of [2-(3)H]glycerol and [1-(14)C]palmitate, were examined in vivo ...

The kinetics of oxidation cyclopentanol, cyclohexanol and cyclooctanol using Chloramine T in NaOH has been studied in the micellar phase using sodium dodecyl sulphate in the temperature range 30°C to 50°C to correlate the oxidation rate with the ring size of the cyclic alcohols. The effect of alcohol concentration, concentration of oxidising agent, ionic strength and temperature on the oxidatio...

Four Mo-based catalysts were prepared via three different synthesis techniques supported on SiO2 and/or SBA-15. By means of complementary in situ characterization techniques, the carburization process and final characteristics these investigated. Additionally, four evaluated for activation CO2 absence presence H2 (reverse water–gas shift, RWGS). The results suggest that reacts a dissociation ca...

In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...

Photosynthetic electron transport in green plants causes the inwardly directed transport of protons across the thylakoid membrane. The release of protons inside is well documented [l-6] . Amongst the various indirect techniques, for measuring pH changes in the submicroscopic internal phase, the one with the permeating pH, indicating dye neutral red, is distinguished by sensitivity and time reso...

Oxidation behavior of metastable mechanical alloys in the Al–Mg binary system has been examined in the context of high-energy density materials and combustion applications. Mechanical alloy powders with compositions ranging from Al0.95Mg0.05 to Al0.5Mg0.5, as well as the component metals, were heated at 20 K/min in oxygen. Differential thermal analysis and thermogravimetric analysis showed that...

The atmospheric oxidation of aromatic compounds is an important source of secondary organic aerosol (SOA) in urban areas. The oxidation of aromatics depends strongly on the levels of nitrogen oxides (NOx). However, details of the mechanisms by which oxidation occurs have only recently been elucidated. Xu et al. (2015) developed an updated version of the gas-phase Caltech Atmospheric Chemistry M...
