Road transport taxation in Europe is undergoing a major and radical shift away from fixed charges and fuel duties towards pricing according to distance travelled and externalities produced. Implementation is underway in some states, change being led by national schemes for the freight sector only. The UK is considering such a system for implementation by 2008, to use global positioning system t...

A novel flavivirus, GB virus C (GBV-C)/hepatitis G virus (HGV), has been detected in chronic liver disease patients. It is known that the viral RNA can be detected in approximately 5% of American blood donors. However, the implications for liver disease and the sites of virus replication remain unknown. Possible sites of virus replication were studied by using cell lines and/or primary cells de...

We have determined the nucleotide sequence of the 5'-terminal region of the hepatitis G virus (HGV) genome in 11 hepatitis patients from three cities in China. Phylogenetic analyses revealed that the Chinese isolates were genetically distinct from previously described West African isolates (type 1) and American, European and East African isolates (type 2), with a mean sequence divergence of app...

Tracking of hypersonic glide vehicles (HGVs) by a constellation tracking and observation system is an important part the space-based early warning system. The uncertainty in maneuver intentions HGVs has non-negligible impact on process. cooperative scheduling multiple satellites environment main problem researched this paper. For problem, satellite decision method that considers HGVs’ proposed....

background : gb virus c (gbv-c) is a flavivirus that was characterized in 1995. the prevalence of gbv-c rna in hiv-in­fected subjects has not been previously studied in iran and was therefore determined. methods: we have investigated serum samples of 80 patients from imam khomeini hospital, tehran, iran, whose hiv in­fection was confirmed in our laboratory by western-blotting. we used nested-pc...

conclusions overall, results of present study were consistent with the data reported earlier base on 5’ ntr in iranian isolates and revealed genotype ir2 is major genotype in iranian hgv-positive patient. it means there are higher similarities between iranian and europe-usa in hgv ns3 gene. results nucleotide blast results emphasized that most similar sequences to ir ns3 sequences were those fr...
