The overall internal pH of the acid-tolerant green alga, Chlorella saccharophila, was determined in the light and in the dark by the distribution of 5,5-dimethyl-2-[(14)C]oxazolidine-2,4-dione ([(14)C]DMO) or [(14)C]benzoic acid ([(14)C]BA) between the cells and the surrounding medium. [(14)C]DMO was used at external pH of 5.0 to 7.5 while [(14)C]BA was used in the range pH 3.0 to pH 5.5. Neith...

In the article science approaches to essence and set of elements for a successful tourism destination development are considered. These helped develop new potential model by integrating two management principles: a) sustainability b) innovations. additional principles should reach higher potentials guarantee better performance. The interrelation with mechanism its is reflected. A central aspect...

Transport of beta-hydroxybutyrate (betaHB) into rat brain was estimated from the early rise in brain/serum 14C ratio after subcutaneous injection of [14C]betaHB. Permeability of the D isomer exceeded that of the L isomer. Permeability of either isomer rose throughout suckling (sevenfold) and declined after weaning to the low, newborn values. This age dependence differed markedly from those of c...

[1] The Kimmeridge Clay Formation (KCF) and its equivalents worldwide represent one of the most prolonged periods of organic carbon accumulation of theMesozoic. In this study, we use themolybdenum (Mo) stable isotope system in conjunction with a range of trace metal paleoredox proxies to assess how seawater redox varied both locally and globally during the deposition of the KCF. Facies with low...
