Description Background – Given the increasingly stringent cooling demands in mid to high-end electronic packages, there is a need for high cooling power density yet robust cooling solutions. Convective liquid cooling using micro-channel heat sinks in single-or two-phase operation has received a lot of attention in recent research. Whereas single-phase cooling is simpler and more robust, two-pha...

BACKGROUND The International Liaison Committee on Resuscitation (ILCOR) now recommends therapeutic hypothermia (TH) (33 °C for 12-24 hours) as soon as possible for patients who remain comatose after resuscitation from shockable rhythm in out-of-hospital cardiac arrest and that it be considered for non shockable rhythms. The optimal timing of TH is still uncertain. Laboratory data have suggested...

Radioactive ions (RIs) and antiprotons (pbars) play a major role in the new planned GSI facility. After shooting 1 GeV/u pulses of up to 1 ∗ 10 primary ions with a length of 50 ns on a production target, secondary RI beams are prepared in a superconducting fragment separator. Pbars originate from a primary 30 GeV proton beam of 1.5∗10 13 particles. A dedicated collector ring (CR) serves for pre...

The paper presents the comparison of optimization-regulation algorithms applied to secondary cooling zone in continuous steel casting where semi-product withdraws most its thermal energy. In production, requirements towards obtaining defect-free semi-products are increasing day-by-day and products, which would satisfy consumers a few decades ago, now far below minimum required quality. To fulfi...

Secondary-treated municipal wastewater (MWW) is a promising alternative to freshwater as power plant cooling system makeup water, especially in arid regions. A prominent challenge for the successful use of MWW for cooling is potentially severe mineral deposition (scaling) on pipe surfaces. In this study, theoretical, laboratory, and field work was conducted to evaluate the mineral deposition po...

We revisit the estimation of the power deposited by the electron cloud (EC) in the arc dipoles of the LHC by means of simulations. We adopt, as simulation input, a set of electron-related parameters closely resembling those used in recent simulations at CERN [1]. We explore values for the bunch population Nb in the range 0.4× 10 ≤ Nb ≤ 1.6× 10, peak secondary electron yield (SEY) δmax in the ra...
