  • METHOD FOR CHARACTERISING THE ORIGIN AND/OR CONDITION OF DISEASED OR HEALTHY CELLS AND USES THEREOF IN BIOLOGY
    Publication number: 20140051116
    Abstract: The invention relates to a method for characterising the origin and/or condition of diseased or healthy cells, characterised in that it includes the measurement of isotopic variations in a natural abundance of elements of cells, the contents of which are modified in a situation of disease, using an isotope-ratio mass spectrometer (abbreviated as IRMS), advantageously using an elemental analyser coupled with an isotope-ratio mass spectrometer (abbreviated as EA-IRMS).

  • Filter having elements with distributed constants which associate two types of coupling
    Patent number: 4992759
    Abstract: A filter having elements with distributed constants is made up of resonators providing two different types of coupling. The use of two types of coupling makes it possible to obtain the desired geometry and in particular to limit the coupling between variable capacitors in the construction of combline filters as well as the construction of filters having two transmission zeros and involving the use of hairpin resonators.
