The concentration of atmospheric carbon dioxide was increased by 200 microliters per liter in a forest plantation, where competition between organisms, resource limitations, and environmental stresses may modulate biotic responses. After 2 years the growth rate of the dominant pine trees increased by about 26 percent relative to trees under ambient conditions. Carbon dioxide enrichment also inc...

China was responsible for 25 per cent of global carbon dioxide emissions in 2012 (Liu 2015). This followed the passing of key milestones in the previous decade. From 2007, China’s per capita carbon dioxide emissions exceeded the world average and it has become the world’s largest contributor to annual carbon dioxide emissions, with the burning of fossil fuels and cement production being two imp...

Simulation experiments are conducted, comparing the effects of a common reduction of CO2 emissions within the European Union to a Swedish unilateral decision to reduce CO2 emissions. A numerical general equilibrium model, GEME3, has been used as analytical tool. The model covers all European Union countries, with production disaggregated into 18 sectors. The 13 consumption goods included are cl...

Supercritical carbon dioxide is a promising green-chemistry solvent for many enzyme-catalyzed chemical reactions, yet the striking stability of some enzymes in such unconventional environments is not well understood. Here, we investigate the stabilization of the Candida antarctica Lipase B (CALB) in supercritical carbon dioxide-water biphasic systems using molecular dynamics simulations. The pr...

A variety of methods is available to quantify uncertainties arising within the modeling of flow and transport in carbon dioxide storage, but there is a lack of thorough comparisons. Usually, raw data from such storage sites can hardly be described by theoretical statistical distributions since only very limited data is available. Hence, exact information on distribution shapes for all uncertain...

Acute respiratory distress syndrome (ARDS) has a substantial mortality rate and annually affects more than 140,000 people in the USA alone. Standard management includes lung protective ventilation but this impairs carbon dioxide clearance and may lead to right heart dysfunction or increased intracranial pressure. Extracorporeal carbon dioxide removal has the potential to optimize lung protectiv...

THIS PAPER REPORTS A METHOD for determining carbonate in carbonate-containing solids by means of the Van Slyke-Neill manometric apparatus, which is widely used for the determination of carbon dioxide in biologic fluids. The method is rapid, convenient, and quantitative, and it makes possible the determination of carbonate in solids by the average clinical laboratory without the purchase of addi...

The oxygen and carbon dioxide requirements of different biotypes of thermophilic campylobacters were investigated by means of (a) quantitative studies, and (b) total growth studies. Oxygen tolerance of the five test organisms differed markedly and varied with the carbon dioxide concentration. At most carbon dioxide concentrations tested, Campylobacter jejuni strains NCTC 11168 and NCTC 11392 to...

In a previous study of the fermentation of lactate by Clostridium lacto-acetophilum (Bhat and Barker, 1947) it was shown that pure cultures of this organism can decompose lactate only when acetate is provided as a second substrate, whereas enrichment cultures of the same organism do not require added acetate. This difference in nutritional requirements indicated a corresponding difference in th...

During the past few years there has been a growing appreciation of the role of carbon dioxide in bacteriology. It has been demonstrated by a number of observers that the presence of carbon dioxide is apparently necessary for growth of all species of bacteria so far studied. Walker (1932) and Gladstone et al. (1935) suggest that the lag phase of the bacterial growth cycle is due to the failure o...
