Localized Plasma Balls
In this paper we numerically construct localized black hole solutions at the IR bottom of the confining geometry of the AdS soliton. These black holes should be thought of as the finite size analogues of the domain wall solutions that have appeared previously in the literature. From the dual CFT point of view, these black holes correspond to finite size balls of deconfined plasma .

Temperature limits | SKF
Temperature limits for the greases used in sealed SKF selfaligning ball bearings are provided in table 1. For temperature limits of other SKF greases, refer to Selecting a suitable SKF grease. When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept. Selfaligning ball bearings.
Laser Cladding
Laser cladding is a cuttingedge welding process that has the capability to modify the surface properties of a substrate with exotic and/or harder materials. In this process, the feedstock in the form of micronsized alloy powder is melted by a laser beam to deposit the durable overlay with a thickness of " to " on the substrate.
Temperature of the milling balls in shaker and planetary ...
· The ball temperature remains below 100 °C in a SPEX 8000 shaker mill and it is cooler when flatended rather than roundended vial is used, although the milling intensity, as measured by the mechanical dose rate, follows the opposite trend. Temperatures over 200 °C are typical in planetary mills operating at similar milling intensities.
