This paper studies the heating load and thermal comfort distribution in a typical office with a mixed radiant and convective heating system for two different locations of radiant heat sources. Accurately estimating the heating load in a mixed heating space requires careful consideration of the energy balance on each room surface and the comfort level in the space. A pure radiant heating system ...

This paper applies various recent panel unit root tests to 14 macroeconomic variables. These variables, observed for the OECD countries since the 50’s, are the same as those considered in the seminal paper by Nelson and Plosser (1982) for the United States. Two distinct generations of tests are used. The first one is based on a cross-sectional independence assumption. If we consider only tests ...

Problem statement: Noise Induced Hearing Loss (NIHL) is one of the most important occupational disease in worldwide. NIHL has been found to be potentiated by simultaneous Carbon monoxide (CO) exposure. Exposure to noise plus CO is common in occupational and environmental settings. Free radicals have been implicated in cochlear damage resulting from exposure to noise and due to CO hypoxia This s...

The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...
