Organic Synthesis: New Vistas in the Brazilian Landscape Anais da ABC (AABC)
PILLI,RONALDO A.; ASSIS,FRANCISCO F. DE.
ABSTRACT In this overview, we present our analysis of the future of organic synthesis in Brazil, a highly innovative and strategic area of research which underpins our social and economical progress. Several different topics (automation, catalysis, green chemistry, scalability, methodological studies and total syntheses) were considered to hold promise for the future advance of chemical sciences in Brazil. In order to put it in perspective, contributions from Brazilian laboratories were selected by the citations received and importance for the field and were benchmarked against some of the most important results disclosed by authors worldwide. The picture that emerged reveals a thriving area of research, with new generations of well-trained and productive...

The problem of discards in fisheries ArchiMer
Morizur, Yvon; Caillart, B; Tingley, D.
Introduction : It is now clear that the world's fishery resources are being subjected to exploitation at or above their capacity to produce maximum sustainable yields. At the same time as these trends are being felt, there is a very large wastage of fishery resources from discarding unwanted catches at sea. At the end of each fishing operation a part of the catch is often returned to the sea after sorting by the fishermen. A 1994 FAO report provided an estimate of global discards in commercial fisheries of 27 millions of tons per year compared to 50 million tons of direct human consumption. A more recent FAO document estimated that discards were in the order of 20 million tons in 1997. The majority of the world's fisheries are multi-species in nature and...
