Quality assurance of the workshop activity - including test facilities

Especially for MS with various boarders it is essential to know the state of the testing system in the neighbour countries. In North Rhine Westphalia a well-established system is working well since years. But how is the situation in other Federal States like Rhineland Palatinate, Hessen or Lower Saxony? All three federal states are following the same EU Directive, but the responsibility of the local authorities is different compared to North Rhine Westphalia. But in all cases we are accepting a sticker on a sprayer throughout the whole Europe. Or how is the quality system in the Netherlands? Following that question a developed questionnaire and parameters for quality control of accepted workshops was provided in the shape of a SPISE Advice. This SPISE Advice was adapted to the local situation in North Rhine Westphalia. With this system a visit of a recognized workshop in the Netherlands was conducted in collaboration with local authorities (SKL). The reason for this visit was to be sure that there will be no problem with the mutual recognition of a tested sprayer. This review showed a good result with a comparable system between the Netherlands and North Rhine Westphalia. Especially in the case for establishing a new system the SPISE Advice was really helpful.Especially for MS with various boarders it is essential to know the state of the testing system in the neighbour countries.

Characterization of Water Dissociation on α\alpha-Al2_{2}O3_{3}(11ˉ02)(1\bar{1}02): Theory and Experiment

The interaction of water with $\alpha$-alumina (i.e. $\alpha$-Al$_{2}$O$_{3}$ surfaces is important in a variety of applications and a useful model for the interaction of water with environmentally abundant aluminosilicate phases. Despite its significance, studies of water interaction with $\alpha$-Al$_{2}$O$_{3}$ surfaces other than the $(0001)$ are extremely limited. Here we characterize the interaction of water (D$_{2}$O) with a well defined $\alpha$-Al$_{2}$O$_{3}$$(1\bar{1}02)$ surface in UHV both experimentally, using temperature programmed desorption and surface-specific vibrational spectroscopy, and theoretically, using periodic-slab density functional theory calculations. This combined approach makes it possible to demonstrate that water adsorption occurs only at a single well defined surface site (the so-called 1-4 configuration) and that at this site the barrier between the molecularly and dissociatively adsorbed forms is very low: 0.06 eV. A subset of OD stretch vibrations are parallel to this dissociation coordinate, and thus would be expected to be shifted to low frequencies relative to an uncoupled harmonic oscillator. To quantify this effect we solve the vibrational Schr\"odinger equation along the dissociation coordinate and find fundamental frequencies red-shifted by more than 1,500 cm$^{\text{-1}}$. Within the context of this model, at moderate temperatures, we further find that some fraction of surface deuterons are likely delocalized: dissociatively and molecularly absorbed states are no longer distinguishable.Comment: Paper: 22 pages, 9 figures , ESI: 6 pages, 1 figur

Decontamination of room air and adjoining wall surfaces by nebulizing hydrogen peroxide

Aim: In 2010, the ASP GLOSAIRTM 400 was introduced in Germany for nebulizing hydrogen peroxide (H2O2). Since there were no results of practical experience, the new method was to be checked under practical conditions for its effectiveness in decontaminating air in rooms, infested with mold after water damage and, at the same time, under experimentally controlled conditions, test surfaces, contaminated with Aspergillus brasiliensis

Results of a healthcare worker (HCW) survey on environmental awareness as an instrument for the preparation of an environmental report for the University Medicine Greifswald

Background: Environmental reporting is increasingly important for medical facilities. Currently, hospitals can determine the content of an environmental report as they see fit

Practices of skin care among nurses in medical and surgical intensive care units: results of a self-administered questionnaire

Dermatitis of hands is a problem among nurses. The aim of this prospective questionnaire based survey was to analyze practice and knowledge of skin care of medical and surgical nurses

Tiling theory applied to the surface structure of icosahedral AlPdMn quasicrystals

Surfaces in i-Al68Pd23Mn9 as observed with STM and LEED experiments show atomic terraces in a Fibonacci spacing. We analyze them in a bulk tiling model due to Elser which incorporates many experimental data. The model has dodecahedral Bergman clusters within an icosahedral tiling T^*(2F) and is projected from the 6D face-centered hypercubic lattice. We derive the occurrence and Fibonacci spacing of atomic planes perpendicular to any 5fold axis, compute the variation of planar atomic densities, and determine the (auto-) correlation functions. Upon interpreting the planes as terraces at the surface we find quantitative agreement with the STM experiments.Comment: 30 pages, see also http://homepages.uni-tuebingen.de/peter.kramer/ to be published in J.Phys.

On Pair Production in the Crab Pulsar

We consider the widespread assumption that coherent pulsar radio emission is based on extended pair production leading to plasma densities highly exceeding the Goldreich-Julian density. We show as an example that the observed low frequency (160 MHz) emission of the Crab pulsar is incompatible to the model of extended pair production. Our results rule out significant pair production if a plasma process is responsible for coherence and the radio emission originates from inside the light cylinder.Comment: accepted for publication in ApJ Letters; 4 pages, no figure
