Autor: A. Schwab, M. Weber, G. Spicher, D. Becker, G. Sinapius, W. Raith, Kelvin G. Lynn, W. Sperber
Publikováno v: Physical Review Letters. 68:3690-3693
The positronium-formation cross section was measured for positron collisions with atomic hydrogen in a crossed-beam experiment. Measurements were made in the energy range of 13 eV\ensuremath{\le}E\ensuremath{\le}205 eV. At E=15\ifmmode\pm\else\textpm

Studies on acid formation and growth of microorganisms in a continuously operating sourdough fermenter
Autor: F. Meuser, G. Spicher, A. Vollmar, Chr. Faber
Publikováno v: Food Biotechnology. 4:185-201
The growth and acid formation of lactic acid bacteria and the growth of yeasts were examined in a specifically designed laboratory fermenter in fermenting sourdoughs under simulated continuous operating conditions. The aim of the investigations was t

Microbiological efficacy of superheated steam. I. Communication: results with spores of Bacillus subtilis and Bacillus stearothermophilus and with spore earth
Autor: G, Spicher, J, Peters, U, Borchers
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 201(6)
For the spores of Bacillus subtilis and Bacillus stearothermophilus as well as for spore earth (acc. DIN 58,946 Part 4 of August 1982), the dependence of resistance on the superheating of the steam used to kill germs was determined. A material (glass

Model tests for the efficacy of disinfectants on surfaces. IV. Communication: dependence of test results on the amount of contamination and the kind of active substance
Autor: J, Peters, G, Spicher
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 201(4-5)
In the assessment of efficacy of surface disinfectants, many influencing factors have to be taken into account. One essential item is whether the surface to be disinfected is clean or soiled. Among the feasible soilings, the blood is of particular co

[Suitability of Bacillus subtilis and Bacillus stearothermophilus spores as test organism bioindicators for detecting superheating of steam]
Autor: G, Spicher, J, Peters
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 199(5)
Biological indicators used to test sterilisation procedures for their efficacy consist of a so-called germ carrier to which the microorganisms used as test organisms adhere. In previous papers we demonstrated that carriers made of filter paper on con

[Microbial resistance to formaldehyde. IIIDependence of the microbial effect on Staphylococcus aureus, Enterococcus faecium and spores of Bacillus stearothermophilus on temperature]
Autor: G, Spicher, J, Peters
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 196(6)
Temperature dependence of microbicidal efficacy of formaldehyde was examined with suspension tests (pH 7.0). Test germs were Staphylococcus aureus, Enterococcus faecium and spores of Bacillus stearothermophilus. The methodology was nearly the same as

[Further studies on the falsification of the steam resistance of bioindicators by superheating]
Autor: G, Spicher, J, Peters, U, Borchers
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 196(2)
As a supplement to a preceding paper (Zbl. Hyg., 194 (1993). 369-279) the resistance of bioindicators has been investigated which differed only in the material of which the carriers are made (filter paper and glass fibre fleece, respectively). The co

[Model tests for effectiveness assay of disinfectants on surfaces. III. Dependence of test results on the type of substances and the test microbes (Staphylococcus aureus, Mycobacterium terrae)]
Autor: J, Peters, G, Spicher
Publikováno v: Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine. 195(2)
A new test method for surface disinfectants was applied to investigate the efficacy of the most important active components of disinfectants to Staphylococcus aureus and Mycobacterium terrae. The test germs were embedded in coagulated blood. Frosted
