“Genetic discrimination” is a topic which currently attracts legal and ethical attention worldwide. Although only a few (often unclear) cases of genetic discrimination have been discussed up to now, many countries nonetheless have felt obliged to react with regulatory measures and anti-discrimination laws. The basic problem is that it is still unclear what the precise term “genetic discrimination”...
Transition metal oxides show fascinating physical properties such as high temperature superconductivity, ferro‐ and antiferromagnetism, ferroelectricity or even multiferroicity. The enormous progress in oxide thin film technology allows us to integrate these materials with semiconducting, normal conducting, dielectric, or non‐linear optical oxides in complex oxide heterostructures, providing the basis...
The combination of magnetic properties with dielectric, semiconducting, or ferroelectric materials in one and the same material [e.g. magnetic semiconductors (MS) or intrinsic multiferroics] – as well as in artificial heterostructures [e.g. ferromagnetic/dielectric heterostructures for magnetic tunnel junctions (MTJs) or artificial multiferroic heterostructures] allows for the design of materials...
The chromatomembrane cell (CMC) was used to extract zinc and copper and to preconcentrate them for their separation from pharmaceutical preparations. The method performance was evaluated at the determination of the enrichment factor, the linearity of response, the reproducibility, the accuracy and the sensitivity. In practice a five-fold enrichment has been enough provided that sample sizes of 0.825ml...
The concentration distribution of an analyte in a chromatomembrane cell (CMC) was examined by using various air samples of different air pollutant (NO 2 ) concentrations and volumes, and the results obtained could be explained by a proposed principle of the concentration distribution of the analyte in the CMC. This principle was for the first time proved experimentally in the present study...
Polycyclic aromatic hydrocarbons (PAH) and extractable organic halogens (EOX) pollute industrial waste waters and need to be controlled continuously by automated procedures. Their sample pretreatment requires extraction first from complex matrices containing surfactants, humic acids, urine and electrolytes besides. When using chromatomembrane cells (CMC) for the extraction with pentane or hexane a...
A simple and rapid procedure for NO 2 determination in air was developed by coupling the chromatomembrane method with a micro-FIA system. A three-hole chromatomembrane cell was successfully applied to on-line preconcentration of atmospheric NO 2 in a solution of 2 g l -1 triethanolamine (TEA) as an aqueous absorbing solution. The lowest volume of an air sample necessary...
The use of impedance derived contractility indices for control of successful systemic lysis after coronary artery thrombosis is demonstrated in three examples.
