UNLABELLED Biodegradable polymers represent a solution for the environment protection: they decrease the landfill space, by declining the petrochemical sources, and offer also an alternative solution for the recycling. MATERIALS AND METHODS The behavior during degradation in the presence of active sludge of some polyvinyl chloride (PVC) based blends with(More)
In this paper, the behavior of modified/unmodified organosolv lignin (Alcell) solutions has been studied. Organosolv lignin was modified with different carboxylic acids, such as oleic, butyric, lactic acids and butyrolactone under cold plasma discharge. The modified lignins were characterized by particle size analysis and zeta potential measurements in(More)
Cellulose-lignin hydrogels (CL), prepared by a two-step procedure consisting in dissolving the cellulose in an alkaline solution at low temperature, followed by the crosslinking reaction with lignin in the presence of epichlorohydrin, were subjected to experimental approaches, additional to those reported before, for their in-depth characterization. Thus,(More)
Cholesterolemia in a population of 100482 inhabitants of the Bihor district, subjected to screening for the risk factors in ischemic cardiopathy were studied. Together with hyperlipidemias other risk factors were detected: arterial hypertension, obesity, diabetes mellitus, smoking, ischemic alterations of the electrocardiogram, the influence of the noxious(More)
