The vulnerability approach is an analytical framework used to assess the impacts caused by changes in socio-ecosystems that are often linked to large external natural events. The vulnerability approach is mobilized by the sciences that deal with the management of environmental risks with the aim to determine the conditions allowing...
It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and some NGOs. However, these continue to be perceived in large measure as...
An international symposium devoted to Research and small-scale fisheries (Durand, Lemoalle, Weber,
1991) in Montpellier (France) in 1989 came from increasing evidence that “the complexity of small scale
fisheries calls for applying knowledge from many fields in combined studies that can take advantage of a
whole range of information”. Has...
This research was undertaken to provide barley growers, processors, and consumers with quality food barley. Because all currently available varieties of food barley are of spring growth habit, the first phase of the research involved agronomic assessment of these varieties under Oregon conditions. Because winter barley usually yields more than...
Après avoir succinctement présenté l'évolution récente et la situation actuelle de la pêche comorienne, on tentera de s'interroger sur les principes autour desquels on peut promouvoir un développement du secteur halieutique, qui dépasse la juxtaposition ou la succession des projets de développement. Pour des sociétés littorales qui, malgré le contexte...
The way in which subjects of different ages copy a complex design
gives an indication of the relative levels of visual perception and
the related developmental trend of overall cognitive development and
left-right hemispheric functioning. The purpose of this study was to
investigate the impact of severe to profound hearing...
The international institutional context for fishery management in the Mediterranean is changing due to the evolution of the General Fisheries Commission for the Mediterranean and the review of the Common Fisheries Policy due in 2002. This changing context offers an ideal opportunity to re-consider the fundamental fishery management strategy. It...
In April 1997, the Council of the European Union (EU) initiated a debate about Community fishing agreements (CFAs). In its conclusions, the Council invited "the Commission to undertake an analysis of the costs and benefits of fishing agreements with the Community". The overall aim is to provide pertinent information to...
Altar (31º 29’ S, 70º 28’ W) is a large porphyry Cu-(Au-Mo) deposit with associated
epithermal Au-(Ag-Cu) veins located in the Cordillera Principal of SW San Juan Province
(Argentina). Altar is a complex magmatic-hydrothermal system formed from several
magmatic and hydrothermal pulses during the middle-late Miocene. New LA-ICPMS U-Pb
ages...
The first committed step in DNA biosynthesis occurs by direct reduction of
ribonucleotides. This reduction is catalyzed by ribonucleotide reductase (RNR), an
enzyme which uses a unique radical mechanism to facilitate the transformation. All four
DNA precursors are synthesized by a single enzyme. Therefore, an intricate pattern of
regulation has...
