The organic electrolyte of tetraethylammonium tetrafluoroborate (TEABF(4)) in the aprotic solvent of acetonitrile (ACN) is widely used in electrochemical systems such as electrochemical capacitors. In this paper, we examine the solvation of TEA(+) and BF(4)(-) in ACN, and the structure, capacitance, and dynamics of the electrical double layers (EDLs) in the TEABF(4-)ACN electrolyte using molecu...

There are many query languages (QLs) that can be used to query RDF and OWL ontologies but neither type is satisfactory for querying OWL-DL ontologies. RDF-based QLs (RDQL, SeRQL, SPARQL) are harder to give a semantics w.r.t. OWL-DL and are more powerful than what OWL-DL reasoners can provide. DL-based QLs (DIG ask queries, nRQL) have clear semantics but are not powerful enough in the general ca...

Background: Inadequate depth of anesthesia leads to release of stress hormones. Electroencephalographic monitoring by bispectral index is a guide to asses the depth of anesthesia. The aim of the present study was to measure the serum cortisol levels as an index of stress response in patients who are candidates for coronary artery bypass graft surgery in two groups of patients. Methods: Seventy-...

axial distributions of plasma and floating potentials, electron number density and the electron energy distribution function (eedf) have been measured in the double layer (dl) region of an he discharge constriction. excitation processes in the constriction region are studied. using a linearization method for the nonstationary balance equations and choosing appropriate discharge conditions, the ...

In this paper the electrophoretic mobility and the electrical conductivity of concentrated suspensions of spherical colloidal particles have been numerically studied under arbitrary conditions including zeta potential, particle volume fraction, double-layer thickness (overlapping of double layers is allowed), surface conductance by a dynamic Stern layer model (DSL), and ionic properties of the ...

The asymmetric unit of the title compound, [Cu(C(4)H(8)NO(3))(C(12)H(8)N(2))(H(2)O)]Cl·2H(2)O, contains a complex cation, a chloride anion and two water mol-ecules. The Cu(II) ion has a distorted square-pyramidal coordination geometry formed by one bidentate phenanthroline ligand, one O,N-bidentate dl-threoninate ligand and one apical water mol-ecule. In the crystal structure, inter-molecular O...

InGaN based c-plane blue LDs on strain relaxed template (SRT) with a reduced absorption loss was demonstrated. The is from 27 cm−1 to 20 cm−1. Due the lower loss, threshold current density improved 51.1 kA/cm2 43.7 kA/cm2, and slope efficiency also increased by factor of 1.22. decomposition layer (DL) in SRT confirmed be major extra source both experimental simulation results. With higher indiu...

In UMTS system level simulations DCH BLER models are used to represent the characteristics of lower layers in order to save simulation time. Usually DCH BLER statistics are taken from link level simulations or only certain fixed values for DCH BLER are used for system level simulations. In this paper we present measurements of UMTS DL DCH BLER for 360kbit/s UDP data traffic (372kbit/s incl. UDP...

A low-frequency instability varying from 10 to 20 kHz has been discovered in the presence of a current-free double layer !DL" in a low-pressure expanding helicon plasma. The instability is observed using various electrostatic probes, such as Langmuir probes floating or biased to ion saturation and emissive probes measuring the plasma potential. A retarding field energy analyzer measuring the io...

Objective: To test the working hypothesis that inflammation underlying precocious and severe coronary atherosclerotic disease in familial hypoalphalipoproteinaemia (FH) can be mediated by up regulation of the innate immune response. Methods and results: 52 patients with FH were compared with 52 healthy controls with regard to immune system markers such as C reactive protein (CRP), soluble inter...
