Diffusional inhomogeneity: gas mixing efficiency in the new-born lung.

Gas mixing and distribution in the lung.

If you really want to be smarter, reading can be one of the lots ways to evoke and realize. Many people who like reading will have more knowledge and experiences. Reading can be a way to gain information from economics, politics, science, fiction, literature, religion, and many others. As one of the part of book categories, gas mixing and distribution in the lung always becomes the most wanted ...

New p53 Gene Mutation in non-Cancerous Mustard Gas Exposed Lung

Objective Mustard gas (MG) is a poisoning chemical, mutagenic and carcinogenic alkylating agent. It is used during World War I and also Iran-Iraq conflict. The p53 tumor suppressor gene is involved in the pathogenesis of malignant disease. The aim of this study is to determine possible mutation in p53 gene of lung sample from mustard gas exposed patients. Material and Methods Twelve lung bio...

Gas Transport in Glassy Polymers: Prediction of Diffusional Time Lag

The transport of gases in glassy polymeric membranes has been analyzed by means of a fundamental approach based on the nonequilibrium thermodynamic model for glassy polymers (NET-GP) that considers the penetrant chemical potential gradient as the actual driving force of the diffusional process. The diffusivity of a penetrant is thus described as the product of a purely kinetic quantity, the pen...
