An Illuminated Gas Heater

An IT Support for an Exhibition of Illuminated Manuscripts

The paper reports on a project which envisages the employ of IPSA, an originally high-specialized digital archive and web environment purposely developed for professional researchers in History of Art and History of Illumination, to enrich and complete visitors experience in a forthcoming exhibition of illuminated manuscripts.

Numerical study of fluid flow and heat transfer in a gas-tank water heater

Influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.Observations show that without a vent hood, there is a downward gas flow in theflu...

Integrase illuminated.

The long struggle to develop effective therapies against human immunodeficiency virus (HIV) continues in earn est. New antiretroviral drugs to prevent integration of the viral genome are undergoing clinical trials. However, the drug development has relied on testing for effectiveness with only limited understanding of the structural aspects of HIV integration. To establish successful infection,...

H2S: an Endogenous Gas

Gases such as NO and CO play important roles both in normal physiology and in disease. In recent years, interest has been directed towards other naturally occurring gases, notably H 2 S, which is produced in body by three enzymes namely CBS (cystathionine beta synthase), CSE (cystathionine gamma lyase) and MST (3-Mercaptopyruvate sulfurtransferase), present in mitochondria and/or cytosols where...
