Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VII. The Assimilation of Carbon Dioxide by Molds.

des Sciences Math6matiques," tome 1, volume 1, page 601, it is added that J. Perott used the term sulerien groups for abelian groups in American Journal of Mathematics, 11, 99 (1889). This matter is somewhat complicated by the fact that C. Jordan used the term abelian group, with a somewhat different meaning from that now commonly assigned to it, in his widely used "Trait6 des substitutions" (1...

Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VIII. The Rôle of Carbon Dioxide in Cellular Metabolism.

Radioactive Carbon as an Indicator of Carbon Dioxide Utilization: VI. On the Possibility of Carbon Dioxide Reduction via the Carboxylase System.

Recent experiments,' carried out with the aid of labeled carbon, have shown beyond any doubt that CO2 enters into the metabolism of a large variety of organisms in the absence of light. As a consequence it has been suggested that CO2 assimilation may be a process of wide-spread occurrence in living systems. The metabolic processes of living organisms are for the most part enzyme catalyzed. The ...

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

The Prevalence of Carbon-13 in Respiratory Carbon Dioxide As an Indicator of the Type of Endogenous Substrate

Isotope discrimination is a common feature of biosynthesis in nature, with the result that different classes of carbon compounds frequently display different (13)C/(12)C ratios. The (13)C/(12)C ratio of lipid in potato tuber tissue is considerably lower than that for starch or protein. We have collected respiratory CO(2) from potato discs in successive periods through 24 hr from the time of cut...
