background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

Values for thermal specific and thermal pain thresholds were determined in 150 healthy volunteers, 67 women and 83 men, aged from 10 to 73 years. Warm-cold difference limen, heat pain and cold pain thresholds were assessed at the face, thenar, medial surface of the upper- and forearm, lateral mammary, lateral umbilical, anterior thigh and lateral leg regions, and lateral aspect of the dorsum of...

We report a first-order structurally-driven Mott transition a t T=357 K in single crystal Ca2RuO4, an isomorph to the superconductor Sr2RuO4. A discontinuous jump in electrical resistivity with a concomitant change in magnetic moment is triggered by a pronounced structural transition from a high temperature tetragonal phase to a low temperature orthorhombic phase. We argue that t h e elastic en...

We introduce the space-dependent correlation function C (Q)(r) and time-dependent autocorrelation function C (Q)(t) of the local tetrahedral order parameter Q identical with Q(r,t). By using computer simulations of 512 waterlike particles interacting through the transferable interaction potential with five points (TIP5 potential), we investigate C (Q)(r) in a broad region of the phase diagram. ...

The influence of disorder on the transport of quantum vortices in one-dimensional arrays of Josephson junctions was studied experimentally. The vortices localize in disordered arrays for small vortex densities resulting in a vanishing transport at low temperatures, whereas, in a periodic array, transport remains possible. For large vortex densities the mobility of vortices is maintained in the ...
