Detection of flavivirus seroconversions in sentinel chicken flocks located in four Australian states are used to provide an early warning of increased levels of Murray Valley encephalitis virus (MVEV) and Kunjin virus (KUNV) activity in the region. During the 2003-2004 season low levels of flavivirus activity were detected in northern Australia with both MVEV and KUNV virus activity detected in...

Rift Valley fever (RVF), which caused epizootics and epidemics among human and livestock populations, occurred in Senegal in 2013-2014. A multidisciplinary field investigation was carried out in 3 regions of Senegal. We found 11 confirmed human cases of Rift Valley fever, including severe cases with encephalitis and retinitis, 1 pool of mosquito (Aedes ochraceus), and 52 animals tested positive...

We describe an angularly asymmetric interface-scattering mechanism which allows to spatially separate the electrons in the two low-energy valleys of bilayer graphene. The effect occurs at electrostatically defined interfaces separating regions of different pseudospin polarization, and is associated with the helical winding of the pseudospin vector across the interface, which breaks the reflecti...

Introduction: Outflow channels on Mars are formed by very energetic floods suggesting catastrophic episodes of concentrated water flows [1]. These floods comes from a gigantic release of water such as in terrestrial glacial surge, but their exact origin is debated. Outflow channels of the Xanthe Terra region east of the Tharsis area are all of the Late Hesperian epoch and their source regions a...

This paper compares the performance of small and medium size subcontractors in the machine tools industry in two different regions of Malaysia, Penang state and Kelang Valley. It is shown that while Penang state has developed a fairly successful small and medium subcontracting industry, Kelang Valley has not. The difference in performance (measured by value-added) is due in part to differences ...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...
