How to keep cool in tough times
Journal of PeriAnesthesia Nursing, 1999Reengineering is no longer an event that has a beginning and an end. It is an ongoing process of change that continues to occur in all types of businesses. Because there is no longer the sense of security that doing a job well will guarantee continued employment, workers have to approach career planning from a different perspective.

Time for a cool head—neuroprotection becomes a reality
Early Human Development, 2005Studies in encephalopathic infants have demonstrated a brief phase of normal cerebral energetics following hypoxia-ischaemia prior to development of delayed energy failure. In experimental models, mild hypothermia has shown a consistent neuroprotective action, although its efficacy is critically dependent on the severity of the primary insult, the ...

Time of Flight system to investigate positronium cooling
The European Physical Journal D, 2012A positronium Time of Flight (TOF) apparatus, conceived to work with continuous positron beams of intensity up to ~106 positrons/s, was developed. The geometry of the TOF chamber and the acquisition chain are described in detail. The performances of the set up were preliminary tested with a laboratory positron beam of ~5 × 103 positrons/s by measuring ...

Life of an oceanic plate: Cooling time and assimilation time
Tectonophysics, 1985Abstract An oceanic plate undergoes two different thermal stages in its life from its creation at the spreading center to its assimilation under the subduction zone: first the cooling stage and secondly the heating stage. Introducing the terms “cooling time” and “assimilation time” as measures of intervals of the former and latter stages, we ...

Modelling Optimal Pre-cooling Time for Buildings
Proceedings of the Eighth International Conference on Future Energy Systems, 2017Energy costs from HVACS is a significant fraction of the operational expenditure of a building. Pre-cooling is a proven demand side strategy to reduce this operating energy cost. However, generating optimal HVAC operating schedule is a nontrivial problem and often, it requires the use of computationally expensive optimization frameworks. In this paper,

Modeling of cooling times for molds with conformal cooling channels and heat sinks
ICALEO 2000: Proceedings of the Laser Applications in the Automotive Industry Conference, 2000In injection molding and die casting, cycle time of the process is dominated by the heat transfer during the solidification and cooling of the part. Molds with conformal cooling and heat sinks with high thermal conductivity can reduce the cycle time considerably.

Braking System Cooling Time Simulation
Heat Transfer: Volume 1, 2003Aircraft braking pads are subject to an extremely severe thermal environment. During a typical landing the carbon brake pads can reach temperatures up to 700–800 K or even more. Between landings during the taxi and parking phase the brakes have to cool off back to their operational limits in a time interval consistent with the average operational time.

Development and modelling of weld cooling time equations
1991The work reported in this thesis investigates ways of developing and modelling weld cooling time equations. This is an important topic as the susceptibility of a weld's heat affected zone to hydrogen cracking is largely governed by the severity of the cooling portion of the weld's thermal cycle.
