Nonlinear mathematical models for the origin of asymmetry in biological moleculesOrigins of life - Tập 6 - Trang 317-366 - 1975

The origin of chemical chirality is probably associated with a difference in the initial concentrations of two separate populations of primeval organic molecules and possibly even two types of primeval organisms and amplified by nonlinear kinetic processes leading to the death of one population. This theory, as originally developed by F. C. Frank of the University of Bristol, is reviewed in this p...... hiện toàn bộ
Predictability of PaO2 in different inert gas-oxygen environmentsOrigins of life - Tập 3 - Trang 206-209 - 1972

Recent experimentation with metabolic changes in rats exposed to thermally isoconductive environments has involved the use of inert gas-oxygen mixtures with different total pressures (PT) and inspired oxygen fractions (F1O2). To determine the FIO2 for each mixture that would result in similar arterial oxygen pressures (P

Probing the presently tenuous link between comets and the origin of lifeOrigins of life - Tập 12 - Trang 125-132 - 1982
R. W. Hobbs, J. M. Hollis
A unique set of millimeter-wave experiments for future cometary space missions is discussed. These experiments could yield answers to many basic questions about the presently undetermined nature of cometary nuclei and inner comae. This same set of experiments, designed to do fundamental cometary research, could simultaneously provide information on whether the accepted biological requirements nece...... hiện toàn bộ
