The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectri...

Loop heat pipes (LHPs) are used in many branches of industry, mainly for cooling of electrical elements and systems. The loop heat pipe is a vapour-liquid phase-change device that transfers heat from evaporator to condenser. One of the most important parts of the LHP is the porous wick structure. The wick structure provides capillary force to circulate the working fluid. To achieve good thermal...

Thermal noise generated by a hot resistor (resistance R) can, under proper conditions, catalyze heat removal from a cold normal metal (N) in contact with a superconductor (S) via a tunnel barrier (I). Such a NIS junction is reminiscent of Maxwell's demon, rectifying the heat flow. Upon reversal of the temperature gradient between the resistor and the junction, the heat fluxes are reversed: this...

The need to understand and quantify the heat transfer paths within tapered-roller bearings is of great importance in the railroad industry since bearing cup temperature measurement is the primary tool utilized in the removal of distressed bearings from service. Experiments were performed to acquire temperature histories at several locations on a stationary bearing subjected to heat sources imbe...
