Can screening and decontamination procedures performed on an outpatient basis reduce the colonization with Staphylococcus aureus and mitigate associated complications in patients undergoing elective hospital procedures? A controlled intervention study (STAUfrei).

Background: Staphylococcus aureus (SA) colonisation increases the risk of wound infections in surgical procedures. Prevention strategies to date have focused primarily on the hospital, although there are recommendations for pre-hospital decontamination at home, which can be performed by patients themselves. The current study aimed to shift the process of screening and decontamination of SA (methicillin-resistant S.

Transfer functions for/international regulatory limits for the safe transport of radioactive materials.

This paper presents a proposed revision of the International Atomic Energy Agency transport regulations, related to theandlimit values used to determine the radioactive transport classification. Based on the 'system', a novel methodology was introduced to deriveandvalues related to scenarios involving external exposure from a distant source. These values are key parameters that respectively represent the total effective dose and total equivalent dose to the skin, from all primary and secondary particles contributing to radiation exposure.

Skin dose contamination conversion coefficients. Benchmark with three simulation codes.

Handling of radioactive material by operators can lead to contamination at the surface of the skin in case of an accident. The quantification of the dose received by the skin due to a contamination scenario is performed by means of dedicated dose coefficients as it is the case for other radiation protection dose quantities described in the literature. However, most available coefficients do not match realistic scenarios according to state-of-the-art of science and technology.

Photons fluence to local skin Dose coefficients and benchmark with three Monte-Carlo codes. Application to the computation of radioactive material transport limits.

Fluence to Local Skin Dose Conversion Coefficients (LSD-CC) are radiological protection quantities used for external radiation exposures which allow the conversion of particle fluences into local skin equivalent dose. The International Commission on Radiological Protection published LSD-CC for electrons with an energy range from 10 keV to 10 MeV. However, the literature does not address these radiation protection quantities for all particle types, in particular for photons.

Measurement of the helicity asymmetry for the reaction : The CBELSA/TAPS Collaboration.

A measurement of the double-polarization observable for the reaction is reported. The data were taken with the CBELSA/TAPS experiment at the ELSA facility in Bonn using the Bonn frozen-spin butanol (C H OH) target, which provided longitudinally-polarized protons. Circularly-polarized photons were produced via bremsstrahlung of longitudinally-polarized electrons.
