Outbreak of West Nile virus causing severe neurological involvement in children, Nuba Mountains, Sudan, 2002.
An atypical outbreak of West Nile virus (WNV) occurred in Ngorban County, South Kordophan, Sudan, from May to August 2002. We investigated the epidemic and conducted a case-control study in the village of Limon. Blood samples were obtained for cases and controls. Patients with obvious sequelae underwent cerebrospinal fluid (CSF) sampling as well. We used enzyme-linked immunosorbent assay (ELISA...
متن کاملBarite, Hematite and Cinnabar Ore Deposits in the Dusina Area, Mid-bosnian Schist Mountains
In the Dusina area, which is built up of Lower Palaeozoic metasediments, Devonian carbonate complex and Upper Palaeozoic metarhyolites unconformably overlain by Upper Permian sediments, numerous ore occurrences have been investigated: (a) "stratabound" metamorphic hematite deposits in the pre-Devonian metasediments; (b) epigenetic veins and pipes of barite (& calcite) with accessory Hg-tetrahed...
متن کاملSolvent Extraction Studies on Uranium using Amine Based Extractants and Recovery from Low Grade Ore Leach Liquors
Neste estudo, extratores à base de amina (Alamine 336, Alamine 308, Alamine 304 e Aliquat 336) diluídos em querosene foram usados para extração de urânio e separação de outros elementos associados. Alamine 336 foi o melhor extrator para o processo de extração de urânio de soluções de sulfato quando comparado com outros reagentes à base de amina, Alamine 308, 304 Alamine 336 e Aliquat 336. O com...

متن کاملUranium phosphate biomineralization by fungi.
Geoactive soil fungi were investigated for phosphatase-mediated uranium precipitation during growth on an organic phosphorus source. Aspergillus niger and Paecilomyces javanicus were grown on modified Czapek-Dox medium amended with glycerol 2-phosphate (G2P) as sole P source and uranium nitrate. Both organisms showed reduced growth on uranium-containing media but were able to extensively precip...
