Environmental influence on the observed relaxation behaviour of two chromium systems
EPR recovery curves were measured for KCr alum and ruby with 2.7% chromium. A considerable influence of the heat transport properties of the bath is observed. Taking care of this influence a spin relaxation time Ï = (0.7 ± 0.2) ms could be observed for ruby and a spin-lattice relaxation time T1 â T-1. For KCr alum an anomalous behaviour of T1 was observed which may be due to a phonon bottleneck
Omgaan met digitale nationale beleidskaarten
In dit werkdocument worden de resultaten besproken van een casestudy die onderdeel is van het project GeO3 - Omgaan met onzekerheid binnen Ruimtelijke Ordening. De directie Platteland van het ministerie van LNV heeft bij het publiceren van het meerjarenprogramma van Agenda Vitaal Platteland geen digitale viewer gepubliceerd omdat men bang was voor verkeerde interpretatie van de digitale kaarten. In dit project is gekeken naar methoden en cartografische oplossingen om voortaan zonder angst voor misinterpretaties digitale nationale beleidskaarten te kunnen verspreiden. De oplossing is gezocht in het opstellen van een handreiking, zodat kaarten ook daadwerkelijk weergeven wat er bedoeld is door de maker
Measurement of the lifetime of the meson using the decay mode
The difference in total widths between the and mesons is
measured using 3.0fb of data collected by the LHCb experiment in 7 and 8
TeV centre-of-mass energy proton-proton collisions at the LHC. Through the
study of the time evolution of and
decays, the width difference is measured to be
where the first uncertainty is statistical and the second
systematic. The known lifetime of the meson is used to convert this to a
precise measurement of the lifetime,
where the first uncertainty is
statistical and the second systematic.Comment: 19 pagers, 3 figure
Approaching donor families: culture, religion and ethnicity
Purpose of review Recent publications have discussed the relationship between ethnic cultural and religious factors and both the willingness and the actual decision to donate organs. A call is made to use this information more effectively. Recent findings The studies reviewed show that attitudes, beliefs and opinions of people, especially those rooted in speicific religious or cultural backgroudns, have not change significantly over the last decade. Views and misconceptions of minorities in different countries seem to have stronger resemblance to views in the societes or regions of orgin, than to the mainstream view of the host countries - Presumably, this software of the mind is quite resistant to change, but badly understood and surrounded with misunderstanding and prejudice about ethnicity, cultural background and religion. Improved understanding can be more effectiviely used to design more effective intervention methods. There are far more suggested approaches for public education and adaptations of the donation process than have been put to practice. Summary Persistence of cultural and religious factors negatively impact donor rates, hence priority should be given to the development of well researched intervention strategies in which the available information is for public education and improvement of the donation process
