Isotopic fractionation study towards massive star-forming regions across the Galaxy
One of the most important tools to investigate the chemical history of our Galaxy and our own Solar System is to measure the isotopic fractionation of chemical elements. In the present study new astronomical observations devoted to the study of hydrogen and nitrogen fractionation (D/H and 14N/15N ratios) of molecules, towards massive star-forming regions in different evolutionary phases, have been presented. Moreover, a new detailed theoretical study of carbon fractionation, 12C/13C ratios, has been done. One of the main results was the confirmation that the 14N/15N ratio increases with the galactocentric distance, as predicted by stellar nucleosynthesis Galactic chemical evolution models. This work gives new important inputs on the understanding of local chemical processes that favor the production of molecules with different isotopes in star-forming regions.

Thirsty Dragon
An inside view of China's quest to become a global wine power and Bordeaux's attempt to master the thirsty dragon it helped create The wine merchants of Bordeaux and the rising entrepreneurs of China would seem to have little in common—old world versus new, tradition versus disruption, loyalty versus efficiency. And yet these two communities have found their destinies intertwined in the conquest of new markets, as Suzanne Mustacich shows in this provocative account of how China is reshaping the French wine business and how Bordeaux is making its mark on China. Thirsty Dragon lays bare the untold story of how an influx of Chinese money rescued France's most venerable wine region from econom...
Enciclopedia Internacional de Pseud·ʼnimos
This Encyclopedia is the first to compile pseudonyms from all over the world, from all ages and occupations in a single work: some 500,000 pseudonyms of roughly 270,000 people are deciphered here. Besides pseudonyms in the narrower sense, initials, nick names, order names, birth and married names etc. are included. The volumes 1 to 9 list persons by their real names in alphabetical order. To make the unequivocal identification of a person easier, year and place of birth and death are provided where available, as are profession, nationality, the pseudonym under which the person was known, and finally, the sources used. The names of professions given in the source material have been translated into English especially for this encyclopaedia. In the second part, covering the volumes 10 to 16, the pseudonyms are listed alphabetically and the real names provided. Approx. 500,000 pseudonyms of about 270,000 persons First encyclopedia including pseudonyms from all over the world, all times and all occupations Essential research tool for anyone wishing to identify persons and names for his research within one single work
