The deep sea is the world's largest ecosystem, with high levels of biodiversity and many species that exhibit life-history characteristics that make them vulnerable to high levels of exploitation. Many fisheries in the deep sea have a track record of being unsustainable. In the northeast Atlantic, there has been a decline in the abundance of commercial fish species since deep-sea fishing commen...

ions: the law initially defines llrightsll in terms 0 f concrete objects and ordinary human actions , but these rights are then treated as llobjects I1 themselves, and made subject to further human llactionsll ; by repeating this process of reification many times, a complex body of commercial law can be developed. Because of their technical complexity, the legal rules at the top levels of this ...

An important recent finding is that testing improves learning and memory. In this article, the authors describe a demonstration that illustrates this principle and helps students incorporate more testing into their learning. The authors asked students to read one text using a Study–Study strategy and one text using a Study–Test strategy. One week later, the authors tested students’ memory for b...

De Vrijer has presented a proof of the finite developments theorem which, in addition to showing that all developments are finite, gives an effective reduction strategy computing longest developments as well as a simple formula computing their length. We show that by applying a rather simple and intuitive principle of duality to de Vrijer’s approach one arrives at a proof that some developments...

A multi-criteria strategy to identify sustainable bio-succinic acid production processes on a commercial scale.

During the past two decades, the involvement of non-academic sponsors of biomedical research, particularly clinical trial research, has increased exponentially. It is estimated that between 1980 and 2003 the overall research and development expenditure by US pharmaceutical companies increased from $2 billion to $33 billion [1]. The sources of funding for biomedical research have also shifted si...
