Effective hydrogen index

Small amounts of oxygen were observed in the C3+ liquid. The use of the effective hydrogen index corrects for this. [Pg.283]

Erythrocytic effect. Hydrogenated coconut oil, administered orally to healthy rats for 10 weeks, produced a significant effect on five of the six classes of erythrocytes identified. The proportion of cells in each class was dependent on the diet. There was no significant effect of diet on erythrocyte filterability index and no statistical correlation between erythrocyte filterability index and morphology " . [Pg.130]

A large number of patents (Table A.4) claim oil and lubricant additives prepared from alkyl vinyl ether-MA copolymers. Antistatic fuel additives are readily prepared from the materials.Long-chain esters (C > 10) of Gantrez AN show possible use as viscosity index improvers for lube oils. " The vinyl ether of hydrogenated sperm oil has also been copolymerized with MA to produce a very effective viscosity index improver. [Pg.451]

The observed effects are controlled by the density of proton distribution. Porosity calibration of most tools is based on the known volume of water. For other fluids—particularly gas—a normalization using a hydrogen index HI is therefore recommended. Hydrogen index is defined as (Appel, 2004 Zang et al., 1989) the ratio between the amount of hydrogen in the sample and the amount of hydrogen in pure water at standard conditions (STP) ... [Pg.100]

Chemical Antioxidant Systems. The antioxidant activity of tea extracts and tea polyphenols have been determined using in vitro model systems which are based on hydroxyl-, peroxyl-, superoxide-, hydrogen peroxide-, and oxygen-induced oxidation reactions (109—113). The effectiveness of purified tea polyphenols and cmde tea extracts as antioxidants against the autoxidation of fats has been studied using the standard Rancimat system, an assay based on air oxidation of fats or oils. A direct correlation between the antioxidant index of a tea extract and the concentration of epigallocatechin gallate in the extract was found (107). [Pg.373]

The variation of deposition temperature has similar effects on the material properties to those on PECVD-deposited material. With increasing temperature (125-650°C), the material becomes more dense (the refractive index extrapolated to 0 eV increases from 3.05 to 3.65). and the hydrogen content is decreased (15 to 0.3 at.%), as well as the microstructure factor (0.4 to 0). The activation energy is 0.83 eV up to a deposition temperature of 500°C. The dark conductivity and AM 1.5 photoconductivity are about 5 x 10 " and 5 x 10 cm , respec-... [Pg.160]

The general or universal effects in intermolecular interactions are determined by the electronic polarizability of solvent (refraction index n0) and the molecular polarity (which results from the reorientation of solvent dipoles in solution) described by dielectric constant z. These parameters describe collective effects in solvate s shell. In contrast, specific interactions are produced by one or few neighboring molecules, and are determined by the specific chemical properties of both the solute and the solvent. Specific effects can be due to hydrogen bonding, preferential solvation, acid-base chemistry, or charge transfer interactions. [Pg.216]
