Hepatitis virus infection in haemodialysis patients from Moldavia.
BACKGROUND Although the epidemiology of hepatitis B (HBV) and C (HCV) now seems well established for Western European countries, in Central and Eastern Europe < 50% of all dialysis centres routinely test for hepatitis C antibodies since testing is not available or is not applied to all patients. This study describes the prevalence, risk factors and clinical significance of HBV and HCV infection...
متن کاملPurification of Wax Additives
Ethoxylated waxes and high molecular weight alcohols can be synthesised from synthetic waxes. The conversions in these syntheses are generally low. A purification process is thus required to ensure good utilization of the reagents and a high purity of the products. Due to the fact that these components are not stable at high temperatures, conventional separation methods are not suitable. Superc...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملFossil embryos deep in the fossil record
Embryos have been found in ‘old’ rocks on four continents, especially in Siberia, Nevada, Australia and China. They have been discovered in sedimentary rocks of even Late Neoproterozoic age, assuming the evolutionary geological column1 (figure 1). The Neoproterozoic is the period, so called, between 1 billion and 550 million years ago. This discovery was in the Doushantuo Formation, Guizhou Pro...
متن کاملSimulating Wax Crayons
We present a physically-inspired model of wax crayons, which synthesizes drawings from collections of userspecified strokes. Paper is represented by a height-field texture, and a crayon is modelled with a 2D mask that evolves as it interacts with the paper. The amount of wax deposition is computed based on the crayon contact profile, contact force, and friction. Previously deposited wax is smea...
