Metarhizium anisopliae, a fungal pathogen of terrestrial arthropods, kills the aquatic larvae of Aedes aegypti, the vector of dengue and yellow fever. The fungus kills without adhering to the host cuticle. Ingested conidia also fail to germinate and are expelled in fecal pellets. This study investigates the mechanism by which this fungus adapted to(More)
Overview: There is much talk of the potential for small, modular reactors (SMRs) to become players in the field of energy provision. These small reactors, which range in size from tens to several hundreds of megawatts-­‐ electric (MWe), are being developed in a dozen International Atomic Energy Agency (IAEA) member states, and encompass a range of both(More)
The capability to build nuclear weapons is a key national security factor that has a profound influence on the balance of international relations. In addition to long-standing players, regional powers and peripheral countries have sought for ways of acquiring and/or developing them. The authors postulate that to express the capabilities, relative positions,(More)
The energy efficiency of hydrogen recovery from mixtures of CO 2 , H 2 O, and H 2 by a polymer electrolyte hydrogen pump (PEHP) has been evaluated. The PEHP pumps protons across the polymer electrolyte, producing [99.99% pure H 2 and a concentrated CO 2 stream. Single stage PEHP experiments recovered 65% of the hydrogen with an energy efficiency of 50%. The(More)
Small modular reactors (SMRs) may provide an energy option that will not emit greenhouse gases. From a commercial point-of-view, SMRs will be suitable to serve smaller energy markets with less developed infrastructure, to replace existing old nuclear and coal power plants, and to provide process heat in various industrial applications. In this paper, we(More)
