Rice (Oryza sativa cv. Jindao 1187) was grown in open-top chambers which contained ambient and enriched C02. C02 elevation stimulated rice tillering during early vegetative stage. However, panicle dry weight per plant did not change at maturity stage. Root biomass was enhanced by high COz. Root / shoot ratio was increased under high C02 at maturity, indicating more carbon allocation to the belo...

Over the last decades overheating in buildings has become a major concern. The situation is expected to worsen due current rate of climate change. Many efforts have been made evaluate future thermal performance and cooling technologies. In this paper, term “climate change resistivity” strategies defined, calculation method provided. A comprehensive simulation-based framework then introduced, en...

We measured forest floor C02 flux in three age classes of forest in the southern Appalachians: 20-year-old, 85-year-old, and old-growth. Our objectives were to quantify differences in forest floor C02 flux among age classes, and determine the relative importance of abiotic and biotic driving variables. Forest floor C02 flux was measured using an openflow infrared gas analyzer measurement system...

This paper presents the simulation study and comparison of C02 and R502 as refrigerants. At first, as a single stage vapor compression refrigeration cycle's refrigerant, C02 can be used in subcritical and transcritical situations. The performances are studied completely. The results show that C02 has the same or better performance compared to R502's in certain temperature ranges. Finally C02 an...

Advances in the apptication of supercritical (SC), gaseous (G), and ]iquid (LQ) C02 hayc been made regarding the interaction with biological materials or organisms. There are sevcral reports dealing with the influences of SC, G, and LQ C02 on proteins,i'2) amino acids,i) enzymes,3'S) and microbial eells.b'7) Kamihara et aL have described that wet cells (water content of 70-90g,h) of baker's yea...

Schaefer, K. E., S. M. Pasquale, A. A. Messier, and H. Niemoeller. 1979. COrinduced kidney calcification. Undersea Biomed. Res. Sub. Suppl.: S143-S153.—Light microscopic examination of kidney tissue of guinea pigs exposed to 1.5% CO*, 2t% 02, and balance N2 for periods as long as 42 days and of rats exposed to the same CO: concentrations for up to 91 days showed that the incidence of focal kidn...

Photoinitiated reactions of H atoms with C 0 2 in C02-HBr complexes have been examined by using ab initio generalized valence bond-configuration interaction calculations. Recent experiments have shown that C02-HBr complexes yield OH -40 times more efficiently than C02-HCI complexes for similar values of hu-&(HX). We find that the calculated equilibrium geometry for the T-shaped C02-HBr complex ...

The reactions of a variety of bis(tricyclohexylphosphine)nickel species with C 0 2 have been studied. The product of the reaction is solvent dependent: in toluene the known complex [NiL2(/7 -C02)]-toluene (L = PCy3) is formed while in ether or pentane a binuclear complex [(NiL2)2(?;-C02)] results through the intermediacy of the solvent free species [NiL2(//-C02)] the structure of which has been...

The effects of C02 elevation on the dynamics of fine root (FR) mass and ectomycorrhizal (EM) mass and colonization were studied in situ in a Florida scrub oak system over four years of postfire regeneration. Soil cores were taken at five dates and sorted to assess the standing crop of ectomycorrhizal and fine roots. We used ingrowth bags to estimate the effects of elevated C02 on production of ...

IT has been shown by Zuntz(l), Alexander Schmidt(2), and Fre'de'ricq(3)2, that the serum of blood contains more C02 than the corpuscles. On the other hand, it is stated that if C02 acts on the serum and corpuscles which have been separated from one another, then the corpuscles contain more C02 than the serum. This has been explained by an interchange of acid and basic radicles between corpuscle...
