Funding priorities: big barriers to small-scale fisheries.

A couple weeks ago, Daniel Pauly and I got the paper Funding Priorities: Big Barriers to Small-scale Fisheries published in the journal Conservation Biology. In our analysis, we try to demonstrate that conservationists attempts to encourage sustainable fisheries at the market level should place at least equal emphasis on eliminating harmful fisheries subsidies as on consumer-based approaches (e...

CONSTRAINED BIG BANG-BIG CRUNCH ALGORITHM FOR OPTIMAL SOLUTION OF LARGE SCALE RESERVOIR OPERATION PROBLEM

A constrained version of the Big Bang-Big Crunch algorithm for the efficient solution of the optimal reservoir operation problems is proposed in this paper. Big Bang-Big Crunch (BB-BC) algorithm is a new meta-heuristic population-based algorithm that relies on one of the theories of the evolution of universe namely, the Big Bang and Big Crunch theory. An improved formulation of the algorithm na...

Medicine on a small scale.

EMBO reports VOL 4 | NO 11 | 2003 ©2003 EUROPEAN MOLECULAR BIOLOGY ORGANIZATION 1008 Over the past few years, nanotechnology has emerged as a new and exciting research field that deals with the design, synthesis and fabrication of structures at the molecular scale. Smallness is not in itself the prime goal; it is rather the expectation that, by manipulating matter at the molecular level, new in...

The effect of small-scale forcing on large-scale structures in two-dimensional flows

The effect of small scale forcing on large scale structures in β-plane twodimensional (2D) turbulence is studied using long-term direct numerical simulations (DNS). We find that nonlinear effects remain strong at all times and for all scales and establish an inverse energy cascade that extends to the largest scales available in the system. The large scale flow develops strong spectral anisotrop...
