1. General experiments 2-(imidazol-1-yl)terephthalic acid (Im-H 2 BDC • HCl) was prepared by a similar process according to the literature. 1 Other reagents were purchased from commercial sources and used as received. N 2 and CO 2 sorption isotherms of Im-UiO-66 (1) and (I-)Meim-UiO-66 (2) were measured by using a Micrometrics ASAP 2420 instrument at 77 K and 273K, 298 K, respectively. Before t...
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...
Aim The aim of this study was to test the feasibility and fidelity of an intervention, Moving On, aimed to increase outcome expectations OEs (i.e. what one expects to obtain or avoid as a result of a behaviour) and exercise among breast cancer survivors. Design Randomized controlled trial. Methods Intervention arm participants will be given a theory-guided booklet that was co-created by the...
The FRS-ESR facility at GSI provides unique conditions for precision measurements of large areas on the nuclear mass surface in a single experiment. Values for masses of 604 neutron-deficient nuclides (30 < or = Z < or = 92) were obtained with a typical uncertainty of 30 microu. The masses of 114 nuclides were determined for the first time. The odd-even staggering (OES) of nuclear masses was sy...
