This paper presents the cultural and archaeological context of the human fossil bones from Muierii Cave, dated by us to the age of 30 150 ± 800 14C years BP (Before Present) or 34 810 ± 927 cal years BP (calibrated years Before Present), and from Cioclovina Cave, dated to the age of 29 000 ± 700 14C years BP or 33 540 ± 832 cal years BP, in the Southern Carpathians. These are among the most ancien
Abstract in French:Cet article contribue à la recherche sur la géopolitique urbaine par une théorisation « extrospective » du pouvoir local sur la scène internationale – c’est-à-dire une orientation du développement socio-économique qui encourage tant la concurrence que la coopération entre les entités métropolitaines au-delà des frontières de l’État-nation. Empiriquement, l’article se concentre sThis article contributes to research on urban geopolitics through an extrospective theorization of local territorial influence on the international stage. Empirically, the article focuses on a comparative study of extrospective development initiatives from Malaga (Spain) and Mazara del Vallo (Sicily) that have recently emerged in response to the effects of the Great Recession. We examine the symbo
Popular science The carbon balance of the forest ecosystems is determined by the uptake and release of carbon. Forests take up carbon dioxide (CO2) by photosynthesis and release by respiration. One part of the assimilated carbon is respired back to the atmosphere by vegetation. The other part is respired by soil microbes which decompose organic material in soil. The microbial respiration is contro
Succinate:quinone reductase catalyzes electron transfer from succinate to quinone in aerobic respiration. Carboxin is a specific inhibitor of this enzyme from several different organisms. We have isolated mutant strains of the bacterium Paracoccus denitrificans that are resistant to carboxin due to mutations in the succinate:quinone reductase. The mutations identify two amino acid residues, His228
Multifunctional proteins, which play a critical role in many biological processes, have typically evolved through the recruitment of different domains that have the required functional diversity. Thus the different activities displayed by these proteins are mediated by spatially distinct domains, consistent with the specific chemical requirements of each activity. Indeed, current evolutionary theo
