The rising global temperature contributes to a strong impact on urban thermal environment and outdoor thermal comfort. Although the existing satellite telemetry methods are convenient to display geographical information. The detail distributions of 3-dimentional radiation properties of the complex urban environment cannot be estimated accurately due to the low resolution and lack of vertical in...

BACKGROUND AND OBJECTIVE Selective photodamage of the retinal pigment epithelium (RPE) is a new technique to treat a variety of retinal diseases without causing adverse effects to surrounding tissues such as the neural retina including the photoreceptors and the choroid. In this study, the mechanism of cell damage after laser irradiation was investigated. STUDY DESIGN/MATERIALS AND METHODS Si...

The fall in body temperature that occurs in babies soon after birth is influenced by the baby's weight and its environmental conditions. The rate of oxygen consumption 1 1/2 hours after birth was unrelated to body temperature and only slightly raised, indicating a limited thermogenic capacity. A radiant heater effectively prevented cooling in babies kept with their mothers in the delivery room....

AIM The aim of this study was to evaluate the effectiveness of forced-air warming for preventing perioperative hypothermia. BACKGROUND Perioperative hypothermia commonly occurs in patients receiving anaesthesia during surgeries. However, the effectiveness of warming systems requires verification. DESIGN Systematic review incorporating meta-analysis. DATA SOURCES We searched OVID, PubMed, ...

Climate science's method of deriving a surface temperature from incoming radiant energy (whose intensity is measured in watts per square meter) is based on the Stefan-Boltzmann formula [1], which in turn refers to a theoretical surface known as a blackbody – something that absorbs and emits all of the radiance it's exposed to. Since by definition a blackbody cannot emit less than 100% of what i...

This article presents an optimization methodology for finding the heater settings that provide spatially uniform transient heating in manufacturing processes involving radiant heating. Equations governing the transient temperature and temperature sensitivity distributions over the product are first derived using an infinitesimal-area technique and then solved numerically to calculate the object...

The simultaneous chemical kinetics and heat transfer model is used to predict the effects of the most important physical and thermal properties (thermal conductivity, reactor temperature and particle size) of the feedstock on the convective-radiant pyrolysis of biomass fuels. The effects of these parameters have been analyzed for different geometries such as slab, cylinder and sphere. Finite di...
