a revised analysis of the effect of long-range nonspherical terms in the intermolecular potential on the second virial coefficient is presented with a preferred hartree-fock-dispersion functional (hfd-c) spherical core treatment of the integrations for small intermolecular distances. a set of modified numerical tables for the accurate calculation of the nonspherical contribution to the second v...

The unique and important feature of plants is their ability to grow usmg sunlight as the source of energy and C02 from the air as the carbon source with water and elements coming from the environment or soil. The process of photosynthesis with light capture, coupled with 02 evolution and C02 fixation, occurs in the chloroplast. This organelle operates in a semi-autonomous fashion with many of i...

To optimize and enhance the value of a previously developed supercritical fluids (SF) process for removing oil from soybean flakes, we devised a two-step, sequential scheme for extraction of oil and phospholipidcontaining fractions using SC-C02 alone or with ethanol. PLs were selectively removed from the flakes using the SC-C02/ethanol mixture. Phosphatidylcholine (PC) and phosphatidylethanolam...

calculating the extra rate in this unit at a series of instants during the course of the manometric experiment. These extra rates are then extrapolated to zero time so as to eliminate changes in the activity of the enzyme during the actual experiment owing to (i) progressive alterations in pH, substrate and buffer concentrations as C02 is taken up or evolved, (ii) destruction brought about byth...

Methods In the solid tumor model, a lump of 350-mg CC-531 tumor cells was placed intraperitoneally in rats having C02 pneumoperitoneum (n = 8), gasless laparoscopy (n = 8), or conventional laparotomy (n = 8). After 20 minutes, the solid tumor was removed through a laparoscopic port or through the laparotomy. In the cell seeding model, 5 x 105 CC-531 cells were injected intraperitoneally before ...

Measurements were made of arterialized capillary carbon dioxide tension and mixed expired carbon dioxide as well as respiratory minute volume, tidal volume and respiratory frequency on 10 subjects during control periods and following 20 days of exposure to submarine atmosphere on two patrols. The physiological dead space was found increased by 60% on the first patrol, and 61 % on the second pat...

INTRODUCTION Firmness and titratable acidity retention in 'Fuji' and 'Braeburn' apples is enhanced by controlled atmosphere (CA) storage (Elgar et al., 1998, Argenta et al., 2002). However, these cultivars are susceptible to development of internal browning with characteristics of CO2-related injuries including brown-heart and cavities in the flesh (Meheriuk et al., 1994; Elgar et al., 1998). T...

The degree of unsaturation of fatty acids was higher in ChIorella vulgaris 1 h cells grown with air (low-CO2 cells) than in the cells grown with air enriched with 2% CO2 (high-CO2 cells). The change in the ratio of linoleic acid to a-linolenic acid was particularly significant. This change of the ratio was observed in four major lipids (monogalactosyldiacylglycerol, digalactosyldiacylglycerol, ...
