background: hepatitis c is a disease with significant global impact. the distribution of hepatitis c virus (hcv) genotypes in mashhad (the northeast and the biggest city after the capital of iran) is unknown. the purpose of this study was to determine the prevalence of hcv genotypes among hcv seropositive patients, and to study the relationship between types, virologic and demographic features ...

The goal of this study was to propose a hierarchically nested classification system comprising four principal levels the Braun-Blanquet for Polish grasslands class <em>Molinio-Arrhenatheretea</em>. Using Cocktail method, we defined consistent criteria delimitation class, three orders, nine alliances, and 45 associations. Formal definitions were prepared using summed cover presence/a...

  With advent and development of DNA recombinant technology and advantages of p. pastoris expression system, fusion (F) protein of PPRV expression, because of effective immunodominant role could be an appropriate candidate for production of recombinant vaccine against PPR disease. In this study, F gene of PPRV Nigeria 75/1 strain (1637 bp) was amplified using RT-PCR and purified. It was then cl...

To describe ultrarelativistic heavy-ion collisions we construct a three-fluid hydrodynamical model. In contrast to one-fluid hydrodynamics, it accounts for the finite stopping power of nuclear matter, i.e. for nonequilibrium effects in the early stage of the reaction. Within this model, we study baryon dynamics in the BNL-AGS energy range. For the system Au+Au we find that kinetic equilibrium b...

The vulnerability of computer nodes due to component failures is a critical issue for cluster-based file systems. This paper studies the development and deployment of mirroring in cluster-based parallel virtual file systems to provide fault tolerance and analyzes the tradeoffs between the performance and the reliability in the mirroring scheme. It presents the design and implementation of CEFT,...
