In order to determine the genetic variability of Polish RHD virus strains and to confirm the presence of genetic variant (RHDVa) subtype the partial nucleotide sequences of capsid protein gene, including two highly variable regions C and E, were examined. Phylogenetic analyses of 15 viral strains obtained over 18 years revealed the presence of three genetic(More)
A new variant of viral haemorrhagic disease of rabbits (VHD) virus, recently detected in Poland and called Blaszki (BLA), gives positive results in enzyme-linked immunosorbent assay (ELISA) and exhibits viral protein of 60 kilodaltons (VP 60), as detected by Western blot analysis. This BLA variant of VHD virus has caused high morbidity and mortality in(More)

This article reviews the actual world FMD situation. In 2000, fifty nine countries officially reported outbreaks of FMD. The disease occurred in Europe (Greece), Asia (Russia, Mongolia, Bangladesh, Cambodia, China, Japan, Laos, Nepal, Pakistan, Philippines, Republic of Korea, Taiwan, Thailand, Vietnam, Iran, Iraq, Turkey, in Caucasian region--Georgia,(More)
Results of platelet aggregation measured with a dual channel aggregometer and with a microplate reader are compared. Platelets in plasma were activated by ADP and by collagen, and thrombin was used for the aggregation study of gel filtered platelets. The results obtained with both instruments were quantitatively and qualitatively similar. A microplate(More)
Rabbit hemorrhagic disease virus (RHDV) which causes a highly contagious disease of wild and domestic rabbits belongs to the family Caliciviridae. It is a small, positive single-stranded RNA virus with a genome of 7.5 kb and has a diameter of approximately 40 nm. In negatively stained electron micrographs the virus shows typical calicivirus morphology with(More)
The aim of this study was to determine the seroprevalence of BTV-specific antibodies in animals imported to Poland from EU countries after 15 June 2006. From 1 January 2007 to 22 January 2008, a total of 10719 samples of sera collected from cattle, goats and fallow deer were tested. Sera were screened using the highly sensitive and specific c-ELISA test and(More)
In this paper a numerical estimation of hydrodynamic torque converter model is discussed. During the estimation it was assumed that the flow through in working area contains multiple flow streams. A contribution of each individual flow stream in transferring torque was assumed based on a pre-selected torque function. Model estimation relied upon proper(More)
This paper describes multi-objective construction optimization of hydrodynamic torque converter with the application of a genetic algorithm. The main optimization criteria were: torque ratio, efficiency, permeability and a range of high efficiencies. Overall 16 variables were selected as main optimized parameters. Among them were: active diameter,(More)
