The current work concerns the optimization process of phenolic compounds solid liquid extraction from grape byproducts at high temperatures and short incubation times. The effect of five experimental parameters (solidliquid ratio, particle size, time, temperature and solvent mixture) mostly believed to affect the extraction process was undertaken. A first response surface methodology experiment...

The quality evaluation and physicochemical parameters assessment of Slovak Austrian monofloral honeys were performed. In total 65 local denoted by beekeepers as acacia (n = 20), rapeseed 10), linden honeydew 6), forest 12) chestnut 7) collected. such moisture content, water activity, electrical conductivity, pH, free acidity, 5‑hydroxymethylfurfural (HMF) content assessed for characterization c...

BACKGROUND Exposure to hand-arm vibrations is a known cause of the Hand-arm vibration syndrome (HAVS), a progressive syndrome beginning with sensory loss and leading to gangrene, making timely diagnosis essential. OBJECTIVES Assessment of the usefulness of 9 diagnostic parameters claimed as being of greatest value in the diagnosis of HAVS, and examination of the complementary diagnostic value...
