Ab initio calculations of electronic states of the dication C02+, using highly efficient configuration-interattion procedures, are reported. For the lower states, energies are believed to be accurate to within 0.2 eV, but the higher states are less reliable. The complexity of the problem is due to mixing of states of radically different character, such as strongly bound chargepolarization state...

The relation of CO2 to the metabolism of Penicillium chrysogenum has been studied in three ways in this work: (1) attempts were made to replace C02; (2) radioactive C1402 was used to determine the conditions under which CO2 fixation occurred; and (3) attempts were made to identify some of the products of CO2 fixation, especially amino acids. These methods, singly or in combination, have been us...

The metabolic fate of C-methanol and l-C-ethanol in the adult larva of Prodenia litura has been investigated in vivo. Following the intersegmental injection of C-methanol (1.2 mg/g. insect), about 70% of the radioactivity was recovered as C02 in the expired air, after 20 hours. Also, about one fourth of the administered dose was recovered as unchanged methanol, during the first six hours. Only ...

Enzyme solutiens of glucoamylase, acid protease, alkaline protease and lipase were treated with micro-bubbles otsupercritical carbon dioxide (SC CO,) fed from a cylindrical filter nozzle. The microbllbbles of SC C02 could increase the CO, concentration in the sample solution from O.4 to O.92molfl at 25 MPa and 350C, and hence could improye the eMciency of inactiyation by about 3 times compared ...

The combustion of fossil fuels (eg coal, oil shale) to generate energy results in the production of alkaline solid wastes @y ash, clean coal technology (CCT) ash, spent shale etc). Reactions involving calcium (Ca) and carbon dioxide (C02) usually control the pH and mobility of inorganic contaminants such as Cd, P b and Se in alkaiine solid wastes. Samples offly ash, spent shale iutd CCT ash wer...

The purpose of this paper is to describe the effects of C02 and N treatments on soil pC02, calculated CO2 efflux, root biomass and soil carbon in open-top chambers planted with Pinus ponderosa seedlings. Based upon the literature, it was hypothesized that both elevated CO2 and N would cause increased root biomass which would in turn cause increases in both total soil CO2 efflux and microbial re...
