Beta Radiation Enhanced Thermionic Emission from Diamond Thin Films
Diamond-based thermionic emission devices could provide a means to produce clean and renewable energy through direct heat-to-electrical energy conversion. Hindering progress of the technology are the thermionic output current and threshold temperature of the emitter cathode. In this report, we study the effects on thermionic emission caused by in situ exposure of the diamond cathode to beta rad...
متن کاملCorrelation and Prediction of Snow Water Equivalent from Snow Sensors
Since 1982, under an agreement between the California Department of Water Resources and the USDA Forest Service, snow sensors have been installed and operated in Forest Service-administered wilderness areas in the Sierra Nevada of California. The sensors are to be removed by 2005 because of the premise that sufficient data will have been collected to allow "correlation" and, by implication, pre...
متن کاملBeta radiation for glaucoma surgery.
BACKGROUND The outcome of glaucoma surgery can be affected by the rate at which the surgical wound heals. Beta radiation has been proposed as a rapid and simple treatment to slow down the healing response. OBJECTIVES To assess the effectiveness of beta radiation during glaucoma surgery (trabeculectomy). SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL)...
متن کاملVisible and near-ultraviolet absorption spectrum of ice from transmission of solar radiation into snow.
Snow is a scattering-dominated medium whose scattering is independent of wavelength at 350-600 nm. The attenuation of solar radiation in snow can be used to infer the spectral absorption coefficient of pure ice, by reference to a known value at 600 nm. The method is applied to clean Antarctic snow; the absorption minimum is at 390 nm, and the inferred absorption coefficient is lower than even t...
