Bacterial biofilms on long-term catheters are a major source of infection. Exposure to ultraviolet C (UVC - 265 nm) light was shown in an earlier study to reduce the number of bacteria substantially on ex vivo treated urinary patient catheters. Very

The molecular and vibrational structure of the title compound (C4-HSL) was studied by experimental and theoretical methods. The infrared (IR) absorption spectrum was measured in the solid state and in CCl 4 suspension. The observed absorption bands w

Bacterial biofilms on permanent catheters are the major sources of infection. Exposure to ultraviolet-C (UVC) light has been proposed as a method for disinfecting the inner surface of catheters. Specification of a UVC-based device for in vivo disinfe

Diagnostic tools for real time and direct gas analysis have been developed. The simultaneous measurements of gas and particle temperatures (280-330 °C) and gas concentrations (CO, CO2, HCl, H2O) are demonstrated in a hot particle-laden flue gas with

It is demonstrated that good predictions of gas concentrations based on measured spectra can be made even if these spectra contain totally overlapping spectral features from nonidentified and nonmodeled interfering compounds and fluctuating baselines

A computer program was produced to make rapid simulations of CO gas spectra at a spectral resolution of 1 cm−1 and at temperatures ranging from 295 to 845 K and concentrations from 5 to 400 mg/m3. The program is based on loadings and scores from th

The minimum amount of a gaseous compound which can be detected and quantified with Fourier transform infrared (FT-IR) spectrometers depends on the signal-to-noise ratio (SNR) of the measured gas spectra. In order to use low-resolution FT-IR spectrome

Kirchhoff’s law of heat radiation, which relates the spectral emissivity and absorptance of a material body, has been demonstrated for a hot gas (CO2) enclosed in a gas cell at a known temperature. The spectral emissivity of a hot gas in an enclosu

An experimental laboratory set-up for high-temperature gas analysis is presented. The set-up, which comprises an FTIR instrument with an internal detector, an external blackbody source and a heated gas cell, can be used to measure the transmissive an
