Overheating of premises is a typical thermal discomfort issue in naturally ventilated primary schools Ho Chi Minh City, Vietnam. Several design parameters were shown to affect the indoor environment. A parametric study was conducted and based on several building performance simulations investigate influences individual air temperatures prevalence overheating schools. The sensitivity analysis in...

Summertime overheating in dwellings temperate climates is widespread. Overheating bedrooms disrupts sleep, degrading health and wellbeing, can be life-threatening. Air-conditioning homes a solution, but expensive adds load onto electricity networks. An alternative to provide safe havens, cool retreat for sleeping when the main bedroom overheats. This paper estimates number of English that might...

On 9 August 1979, 62 (30.8%) of 201 workers and one of 60 management personnel in a polyvinyl chloride (PVC) fabricating plant developed acute upper and lower respiratory irritation, headache, nausea, and fainting. All were taken to hospital; none died. Sixty of the patients were women. Interviews two weeks later with 57 affected and 14 unaffected workers disclosed that illness had followed exp...

Surfaces which do not exhibit surface melting below the melting point (nonmelting surfaces) have been recently observed to sustain a very large amount of overheating. We present a theory which identifies a maximum overheating temperature, and relates it to other thermodynamical properties of the surface, in particular to geometrical properties more readily accessible to experiment. These are th...

The heating of a semiconductor laser bar imbedded between two heat spreaders has been studied theoretically and experimentally. The model included the p-cladding layer, active region, n-cladding layer, and n-substrate. Heat sources from the active region and both cladding layers were considered. An analytical relation was obtained between the temperature distribution in the laser and the bar ge...

Constant temperature and pressure molecular-dynamics simulations in conjunction with constant pressure and enthalpy simulations, designed to examine the threshold behavior in laser ablation, demonstrate that the rate of homogeneous nucleation (explosive boiling) increases sharply in a very narrow temperature range at approximately 90% of the critical temperature. Moreover, the homogeneous nucle...
