- Abstract
Magnetic-field uniformity is of the utmost importance in experiments to measure the electric dipole moment of the neutron. A general parametrization of the magnetic field in terms of harmonic polynomial modes is proposed, going beyond the linear- gradients approximation. We review the main undesirable effects of nonuniformities: depolarization of ultracold neutrons and Larmor frequency shifts of neutrons and mercury atoms. The theoretical predictions for these effects were verified by dedicated measurements with the single-chamber neutron electric-dipole-moment apparatus installed at the Paul Scherrer Institute.

- Abstract
We report on a search for ultralow-mass axionlike dark matter by analyzing the ratio of the spin-precession frequencies of stored ultracold neutrons and 199Hg atoms for an axion-induced oscillating electric dipole moment of the neutron and an axion-wind spin-precession effect. No signal consistent with dark matter is observed for the axion mass range 10−24≤ma≤10−17 eV. Our null result sets the first laboratory constraints on the coupling of axion dark matter to gluons, which improve on astrophysical limits by up to 3 orders of magnitude, and also improves on previous laboratory constraints on the axion coupling to nucleons by up to a factor of 40.

- Abstract
We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole moment (EDM) of the neutron. We have extended and enhanced our earlier analysis to include recent developments in the understanding of the effects of gravity in depolarizing ultracold neutrons; an improved calculation of the spectrum of the neutrons; and conservative estimates of other possible systematic errors, which are also shown to be consistent with more recent measurements undertaken with the apparatus. We obtain a net result of dn=−0.21±1.82×10−26 e cm, which may be interpreted as a slightly revised upper limit on the magnitude of the EDM of 3.0×10−26 e cm (90% C.L.) or 3.6×10−26 e cm (95% C.L.).

Veertig procent van de Nederlanders rapporteert klachten van het bewegingsapparaat. De gevolgen voor medische consumptie en verzuim van nek- en rugklachten zijn aanzienlijk. Deze studie richt zich primair op de rol van de lichamelijke en psycho-sociale belasting op het ontstaan van rug- en nekklachten. Het betreft dan zowel de belasting op het werk als in de vrije tijd en betreft dus omgevings- en gedragsfactoren die door middel van preventief beleid kunnen worden beïnvloed. In de bedrijfsgezondheidszorg wordt veelal gerefereerd aan het model belasting-belastbaarheid waarin centraal staat dat niet zozeer de lichamelijke en psychische belasting op het werk als wel de verhouding tussen deze belasting en de belastbaarheid van belang zijn voor het ontstaan van klachten. De lichamelijke en psychische belastbaarheid worden in dit onderzoek, hoewel zij niet primair onderwerp van studie zijn, dus wel uitgebreid bepaald om de rol van de belastende factoren valide te kunnen onderzoeken.

Literatuur over preventieve maatregelen op het gebied van Repetitive Strain Injuries (RSI) stelt dat meerdere korte pauzes in een werkdag lichamelijke klachten kunnen verminderen en soms de productiviteit verhogen. In dit artikel wordt een praktijkstudie in drie bedrijven besproken, waaruit blijkt dat het opdelen van de reguliere ochtend- en middagpauzes in meer gespreide kortere pauzes succesvol is als de pauzes minimaal tien minuten duren. Ook is het raadzaam de totale pauzetijd per dag iets te vergroten.

Het Ministerie van SZW heeft in het najaar van 1993 een 'monitorstudie stress en lichamelijke belasting' uit laten voeren in bedrijven in diverse bedrijfstakken, waarvan het doel was risico's en preventiemaatregelen in bedrijven op het gebied van stress en fysieke belasting te inventariseren. Het monitorinstrument is een periodiek instrument, zodat er op termijn trends kunnen worden gevolgd. TNO Preventie en Gezondheid is verzocht om de inmiddels verzamelde gegevens nader te analyseren. In dit rapport wordt verslag gedaan van de resultaten van deze analyses en wordenaanbevelingen gedaan voor de verbetering van het instrumentarium. Het project kende diverse onderzoeksvragen die achtereenvolgens in de verschillende delen vanhet rapport behandeld worden. Eerst wordt de vraag naar de kwaliteit van het monitorbestand en het monitorinstrument besproken. Vervolgens wordt een beschrijving gegevenvan de bevindingen ten aanzien van de risicofactoren, het preventiebeleid en de mogelijke belemmerende en bevorderende factoren in de steekproef. Het monitormodel wordt geanalyseerd en geëvalueerd. Nagegaan wordt of op basis van deze evaluatie tot een zeker typologie van bedrijven gekomen kan worden. Tot slot worden de conclusies samengevat en wordt besproken wat een en ander betekent voor het monitorinstrument en de toepassing ervan in de toekomst.

We outline the experimental concept and key scientific capabilities of AION (Atom Interferometer Observatory and Network), a proposed UK-based experimental programme using cold strontium atoms to search for ultra-light dark matter, to explore gravitational waves in the mid-frequency range between the peak sensitivities of the LISA and LIGO/Virgo/ KAGRA/INDIGO/Einstein Telescope/Cosmic Explorer experiments, and to probe other frontiers in fundamental physics. AION would complement other planned searches for dark matter, as well as probe mergers involving intermediate mass black holes and explore early universe cosmology. AION would share many technical features with the MAGIS experimental programme in the US, and synergies would flow from operating AION in a network with this experiment, as well as with other atom interferometer experiments such as MIGA, ZAIGA and ELGAR. Operating AION in a network with other gravitational wave detectors such as LIGO, Virgo and LISA would also offer many synergies.
