Patients reporting sensitivity to multiple chemicals at levels usually tolerated by the healthy population were administered standardized questionnaires to evaluate their symptoms and the exposures that aggravated these symptoms. Many patients were referred for medical tests. It is thought that patients with chemical sensitivity have organ abnormalities involving the liver, nervous system (brai...
When an adequate amount of an antigenie chemical such as dinitroehlorobenzene (DNCB) is applied to the skin of a guinea pig, an allergic contact sensitivity to that compound may result; this sensitivity is analogous to contact sensitivity in man. After the appearance of sensitization, however, further application of the same chemical to the skin may eventually produce a specific depression of s...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
The enhancement of performance with a decrease in sensitivity of the propellant, have been considered in energetic materials research and development centers. Therefore, efforts to remove nitroglycerin from the common formulations while maintaining the efficiency of the propulsion system has been made, Which led to a new technology so called Extruded Composite Low Sensitive Propellant (ECL). Th...
