Cool can be thought about on three levels; the having of cool things, the doing of cool stuff and the being of cool. Whilst there is some understanding of cool products, the concept, of being cool is much more elusive to designers and developers of systems. This study examines this space by using a set of pre-prepared teenage personas as probes with a set of teenagers with the aim of better und...
An analysis of the strati®cation decay in thermally strati®ed vertical cylindrical cool storage systems is presented using a one dimensional conjugate heat conduction model. The degree of thermal strati®cation depends upon the length to diameter ratio, wall thickness to length ratio, the thermo-physical properties of the material of the storage tank, the type and thickness of the insulation and...
Background and purpose: Heat is a common type of energy that is produced during industrial processes in many work places. Workers who are working in hot areas may be exposed to heat stress. The aim of this study is to evaluate the effect of a designed cool spot on reduction of Mean Radiation Temperature (MRT) and Wet Bulb Glob Temperature index (WBGT) on a group of furnace workers. Materia...
Renewable energy supplies are steadily gaining increasing importance in all the countries. In particular, solar energy, being non-polluting, clean and inexhaustible, has received wide attention among scientists and engineers. Though there are many advantages, an important factor is that solar energy is time dependent energy source with an intermittent character. Hence some form of thermal energ...
Policies for climate mitigation on land rarely acknowledge biophysical factors, such as reflectivity, evaporation, and surface roughness. Yet such factors can alter temperatures much more than carbon sequestration does, and often in a conflicting way. We outline a framework for examining biophysical factors in mitigation policies and provide some best-practice recommendations based on that fram...
The Facility for Low-energy Antiproton and Ion Research (FLAIR) recently got part of the FAIR core project. A large part of the wide physics program decisively relies on new experimental techniques to cool and slow down antiprotons to 20 keV, namely on the development of an ultra-low energy electrostatic storage ring (USR). For the USR to fulfil its key role in the FLAIR project, the developmen...
This paper presents an optimization strategy for supermarket refrigeration systems. It deals with one special condition when the extremely high outdoor temperature causes the compressor to saturate, and work at its maximum capacity. In a traditional control, refrigerated foodstuffs inside display cabinets will suffer from a consequential higher temperature storage, which is detrimental to the f...
stallions diluted at a ratio of 3:1 (extender: semen) with a commercially available stallion semen extender (Exodus Breeders Supply, York, PA) and packaged into each of the containers. Three sets of containers per season (winter and summer) where commercially shipped from Tucson, AZ to Springfield, MO with overnight delivery. Spermatozoal motilities were evaluated utilizing CASA following shipm...
The benign environment and long confinement times obtained with ion storage techniques have led to some unique experiments in the area of precision measurements and fundamental constants. This is perhaps epitomized by the single electron g factor measurements at the University of Washington in which a precision of 4 parts in 10” has been attained. Now, use of lasers to cool stored ions has allo...
