It was shown in a previous paper (3) that the incorporation of carbon dioxide into organic linkage by cattle retina proceeded at a uniform rate under aerobic conditions when pyruvate was the only substrate supplied. Under anaerobic conditions, however, a uniform rate was observed only so long as a supply of glucose was present during the incubation. These observations reflect the need for a cou...

Using of natural lighting has come into prominence in constructed buildings, especially in last ten years, under scope of energy efficiency. Natural lighting methods are one of the methods that aim to take advantage of day light in maximum level and decrease using of artificial lighting. Increasing of day light amount in buildings by using suitable methods will give optimum result in terms of c...

Increasing user comfort and reducing operation costs have always been primary objectives of lighting control strategies in a building. This paper proposes an architecture of the lighting control system for a daylit office. The system consists of the lighting controller, A/D & D/A converter, dimmable LED lights, and the lighting management software. Verification tests are conducted using the pro...
