In the present paper, we have presented a Maxwellian boundary-type solution for total internal reflection with unbounded incident waves at an interface between two nonabsorbing media, in which the instantaneous, time varying, and time averaged radiant fluxes have been determined at all points in the two media. Solutions for the s and p polarizations were found for which the instantaneous tangen...

The objective of this study is to improve the design of hydronic radiant panel systems through the understanding of the thermal performance of panel systems. The scope of this study includes performing experiments using testing facilities and the radiant panel ceiling in the Energy Research House, and developing a theoretical model that can predict heat transfer from a radiant ceiling panel. In...

In the last five years, everolimus has demonstrated efficacy in the treatment of neuroendocrine tumors (NETs) of different origins; its efficacy and safety were explored in the RADIANT trials, the last of which (RADIANT-4) has been recently published (December 2015). Overall, evidence collected from the RADIANT studies holds promise to change clinical practice for the treatment of NETs.In this ...

The energy performance of radiant slab cooling relative to conventional air systems to be clarified for climates from cold and dry to very hot and humid. EnergyPlus simulations were used to compare the energy performance of 1) radiant slab cooling combined with a dedicated outdoor air system and 2) a variable air volume system. Simulation results show that the radiant slab system provided 10% t...

Twenty-six bicycle helmets and their associated visors were characterized for radiant heat transfer using a thermal manikin headform in a climate chamber to assess their ability to protect the wearer from heating by the sun. A single configuration for applied radiant flow of 9.3 W was used to assess the roles of the forward and upper vents and the visor. The helmets shielded 50-75% of the radia...

The body temperatures of infants weighing less than 1500 g under radiant warmers during routine care were documented in the first week of life. Ten infants (median gestational age 28 weeks, median birthweight 913 g) were studied. During 30 nursing interventions (mean 9.2 minutes) mean oesophageal and foot temperature changed 0 degrees C and -0.11 degrees C, respectively. A radiant warmer may li...

BACKGROUND Increasing radiant exposure offers a means to increase treatment efficacy during laser-mediated treatment of vascular lesions, such as port-wine stains; however, excessive radiant exposure decreases selective vascular injury due to increased heat generation within the epidermis and collateral damage to perivascular collagen. OBJECTIVE To determine if cryogen spray cooling could be ...

The personal radiant exposure distribution of solar erythemal UV in tree shade for an upright posture was measured, with measurements over the whole summer for a total of 17 trees. For each tree, the personal radiant exposure distribution was measured for both the morning and afternoon periods. The exposure ratios averaged over all the trees and over the morning and afternoon periods ranged fro...

Radiant ceiling cooling panels require an accurate and sensitive control system to avoid condensation; this is achieved by adjusting the temperature of radiant in adequate time. This study investigated a prediction model for dew-point attached air layer panels. When number position people indoors change, can predict change purpose panel time prevent condensation. The influence different factors...
