12 Kansas Nursing Occupational Outlook 2002-2012 Compiled by Terri Roberts, J.D., R.N. The Kansas Department of Labor recently released a study of occupational employment throughout the state. The data was compiled using data collected from the unemployment insurance program and the Occupational and Employment Survey (OES). The study projects employment by industry and occupation from the year ...

This study proposed a simple method to evaluate the spectral reflectance of inner wall vacuum chamber. A for calculating emission coefficients by taking chamber into account was proposed. Furthermore, plasma diagnosis based on optical spectroscopic (OES) measurement performed so as obtain radial dependence electron temperature Te and density Ne radio frequency inductively coupled Argon (Ar) app...
This study presents the implementation of a portable module designed for autonomous analysis sea-surface inorganic nutrients onboard vessels opportunity, as an additional tool assessing levels eutrophication risk. The was carried out during August-mid-September 2019 in Ria de Arousa and outer shelf area (NW-Iberian coastal upwelling system). During this period, distributions measured concentrat...
Abstract We present a non-invasive approach for determining plasma parameters such as electron temperature and density inside radio-frequency ion thruster (RIT) using optical emission spectroscopy (OES) in conjunction with principal component analysis (PCA). Instead of relying on theoretical microscopic model the to extract from OES, an empirical correlation is established basis conducting simu...
Low-temperature and low-pressure plasma was investigated by OES (optical emission spectroscopy) in the range 200–1100 nm. For displaying measured emission spectra and identification of spectrum lines the software Spectrum Analyzer was used. Two modes of glow discharge present in the DC cylindrical magnetron apparatus which were previously researched by a mass spectrometer were studied by OES. T...
While GDMS is the technique of choice for high sensitivity metals and semiconductor analyses, there are no commercially available radio frequency-GDMS sources. Thus, bulk non-conductive materials must be ground to a powder, mixed with metal, and pressed to form a conductive disk. The analysis of thick oxide or polymer layers is not available directly. In some cases, a conductive metal mask (cal...
Abstract The deposition process using the sputtering method is a technique that produces thin layer. can be used with some modifications made to system. One of identifications through results Optical Emission Spectroscopy (OES) spectrum. By analyzing OES spectrum in system, it seen condition plasma formation chamber. gas system Argon. varying voltage, flow rate, pressure and temperature substra...
