Four new species of Anatomidae (Mollusca: Vetigastropoda) from the Indian Ocean (Reunion, Mayotte) and Australia, with notes on a novel radular type for the family

Four new species of Anatomidae are described: Anatoma herberti n. sp. with strong axial sculpture on the shoulder and base; A. austrolissa n. sp. with almost smooth sculpture except for axial cords in the adumbilical half of the base; A. boucheti n. sp. with sunken protoconch and selenizone that starts after more than one teleoconch I whorl; and A. fl exidentata n. sp. with a highly modifi ed r...

A Novel Heuristic Optimization Methodology for Solving of Economic Dispatch Problems

This paper presents a biogeography-based optimization (BBO) algorithm to solve the economic loadDispatch (ELD) problem with generator constraints in thermal plants. The applied method can solvethe ELD problem with constraints like transmission losses, ramp rate limits, and prohibited operatingzones. Biogeography is the science of the geographical distribution of biological species. The modelsof...

Cracking the Polyketide Code

PLoS Biology | http://biology.plosjournals.org For half a century, natural products from microorganisms have been the main source of medicines for treating infectious disease. The most important chemical class of these antibiotics, apart from the penicillins, is the polyketides. They are made by the stepwise building of long carbon chains, two atoms at a time, by multifunctional enzymes that de...
