Marked inflammation of the cornea (keratitis solaris) is often observed after exposure to strong solar radiation, especially in high altitudes and snow-covered terrain. Using the action spectrum and the solar spectrum, the radiant exposure causing keratitis solaris was calculated for a horizontal surface. The parameters selected were altitude, season, ozone content and albedo. The radiant expos...

The scattering of a partially coherent beam by a deterministic, spherical scatterer is studied. In particular, the Mie scattering by a Gaussian Schell-model beam is analyzed. Expressions are derived for (a) the extinguished power, (b) the radiant intensity of the scattered field, and (c) the encircled energy in the far field. It is found that the radiant intensity and the encircled energy in th...

Multi resolution, high temporal fire monitoring and intensity mapping using Himawari-8 Advanced Himawari Imager data [3] This study is focused on utilising the multi-resolution and high frequency data from Advanced Himawari Imager to develop new algorithms for fire line mapping and fire intensity calculation. Two algorithms are proposed for fire line mapping and fire radiant energy: calculation...

In residential heat pump systems, the motivation for secondary loop systems is to allow for the use of flammable or toxic refrigerants with lower global warming potentials than the currently employed HFC refrigerants. The addition of radiant panels as integral building components (embedded in concrete at construction or attached to the underside of wood flooring) is becoming more common. Combin...

The problem of reconstructing the coherent-mode structure of an optical field with unknown crossspectral density function is solved by means of optimal approximating the measured radiant intensity. An alternative field is defined with the coherent-mode structure calculated for the chosen orthonormal basis. An effciency of the proposed technique is illustrated with the results of a numerical sim...

Patient warming significantly decreases the risk of surgical site infection. Recently there have been concerns that forced air warming may interfere with unidirectional airflow, potentially posing an increased risk of infection. Our null hypothesis was that forced air and radiant warming devices do not increase the temperature and the number of particles over the surgical site when compared wit...

The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...

This study is focused on investigating the effectiveness of low heat accumulation asphalt mixture and its impact on the urban heat environment. Infrared radiation experiments showed that the temperature of the asphalt mixture decreased with the increase in far-infrared radiant material. The results also revealed that, compared to asphalt with 0% far-infrared radiant content, the asphalt materia...
