Optical emission spectra ~OES! from CH4/N2 rf plasmas, which are used for the deposition of nitrogen-containing hydrogenated amorphous carbon ~a-C:H:N! thin films, have been characterized. Previously unidentified spectral lines have been assigned to atomic N. Further identified species include CH, H, H2, N2, N2 1 , N, and CN. Variations between spectra from the pure CH4 or N2 plasmas and the mi...

Current waste management policies favor biogases (digester gases (DGs) and landfill gases (LFGs)) valorization as it becomes a way for energy politics. However, volatile organic silicon compounds (VOSiCs) contained into DGs/LFGs severely damage combustion engines and endanger the conversion into electricity by power plants, resulting in a high purification level requirement. Assessing treatment...

Yogurt, a traditional Turkish dairy product is common in all region of Turkey. The different heavy metals were determined in commercial yogurts by inductively coupled plasma optical emission spectrometer (ICP–OES). Concentrations of calcium (Ca), phosphorus (P), sodium (Na), magnesium (Mg), aluminum (Al), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), boron (B), molybdenum (Mo), cadmium (Cd...

Regional oxidative metabolism was studied in vivo. Oxygen availability was monitored from polarographic electrodes in frontal cortical and subcortical tissue. The rate of oxygen extraction in these regions was estimated at frequencies of up to 3 measurements per minute. Transient ischemia of the frontal regions was induced and the resultant decay in the oxygen trace was analyzed kinetically. Th...

An Organic Embedded System (OES) architecture is developed for sustainable performance using SRAM-based Field Programmable Gate Arrays (FPGAs), an Organic Computing (OC) observer/controller organization, and regeneration with Genetic Operators. Innovations include availability during online regeneration, aging and outlier driven repair assessment, and a uniform design for Autonomic Elements (AE...

A simple and rapid method for the determination of Ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) coupled with least-squares support vector machine regression (LS-SVM) is reported. By evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination of Ba abundan...

TOWARDS A COMPLETE PLASMA DIAGNOSTIC SYSTEM by Dong Wu Zhao Doctor of Philosophy in Engineering-Electrical Engineering & Computer Sciences University of California at Berkeley Professor Costas J. Spanos, Chair We have set up a plasma diagnostic system with three sources of signals, OES, RF, and machine signals. CF2 OES lines 275 nm and 321 nm are found to be better than any other signals for po...

The performance of glow discharge optical emission spectroscopy and mass spectrometry for oxygen determination is investigated using a set of new conductive samples containing oxygen in the percent range in three different matrices (Al, Mg, and Cu) prepared by a sintering process. The sputtering rate corrected calibrations obtained at standard conditions for the 4 mm anode (700 V, 20 mA) in GD-...

Internationally, it is a priority to develop and implement semantically interoperable health information systems.[1] One required technology is the use of standardised clinical terminologies. The terminology, SNOMED CT, has shown superior coverage compared to other terminologies in multiple clinical fields. The aim of this paper is to analyse SNOMED CT implementation in an Electronic Health Rec...

This study describes the use of a composite nitrate salt solution as a precursor to synthesize CeO2 and Gd2O3-doped CeO2 (GDC) nanoparticles (NPs) using an atmospheric pressure plasma jet (APPJ). The microstructures of CeO2 and GDC NPs were found to be cubical and spherical shaped nanocrystallites with average particle sizes of 10.5 and 6.7 nm, respectively. Reactive oxygen species, detected by...
