Rare-earth ions in dielectric crystals are interesting candidates for storing quantum states of photons. A limiting factor on the optical density and thus the conversion efficiency is the distortion introduced in the crystal by doping elements of one type into a crystal matrix of another type. Here we investigate the system Pr3+:La-2(WO4)(3), where the similarity of the ionic radii of Pr and La mi
We perform a review of various approaches to the implementation of quantum memories, with an emphasis on activities within the quantum memory sub-project of the EU integrated project "Qubit Applications". We begin with a brief overview over different applications for quantum memories and different types of quantum memories. We discuss the most important criteria for assessing quantum memory perfor
People’s accumulated local capacity is increasingly recognized to be critical in enhancing disaster resilience and transformation. Nevertheless, citizens’ coping strategies are little known or documented, and hardly considered in city authorities’ and aid organizations’ work. Against this background, this study provides an overview and systematization of citizens’ strategies to cope with increasin
The aim of this paper is to present a model for creating a more coherent concept, designed to meet the demands of the multidisciplinary field of Sociology of Law. This model is built on an ontological analysis that can incorporate different perspectives. The suggested analysis is mainly founded on the Aristotelian concepts of ‘essence’ and ‘accident.’ Thus, the method is concerned with distinguish
Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of
This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying
In this study, we sought evidence for alpha-synuclein (ASYN) expression in oligodendrocytes, as a possible endogenous source of ASYN to explain its presence in glial inclusions found in multiple system atrophy (MSA) and Parkinson's disease (PD). We identified ASYN in oligodendrocyte lineage progenitors isolated from the rodent brain, in oligodendrocytes generated from embryonic stem cells, and in
Background: An association between N-acetyltransferase 2 (NAT2) slow acetylation and bladder cancer has been consistently observed in epidemiologic studies. However, evidence has been mainly derived from case-control studies and was sparse from cohort studies. We evaluated the association between NAT2 slow acetylation and bladder cancer in a case-control study nested in the European Prospective In
Background Ischemic heart disease and stroke are two severe types of cardiovascular disease (CVD), a major contributor to the global burden of disease. The preventive framework currently includes promotion of both adequate cardiorespiratory and muscular fitness. Although muscle fitness is established as an indicator of health, it is currently unknown whether muscle strength is associated with lat
Background: In 2007 the World Cancer Research Fund (WCRF) and the American Institute of Cancer Research (AICR) issued 8 recommendations (plus 2 special recommendations) on diet, physical activity, and weight management for cancer prevention on the basis of the most comprehensive collection of available evidence. Objective: We aimed to investigate whether concordance with the WCRF/AICR recommendati
Background: The higher risk of death resulting from excess adiposity may be attenuated by physical activity (PA). However, the theoretical number of deaths reduced by eliminating physical inactivity compared with overall and abdominal obesity remains unclear. Objective: We examined whether overall and abdominal adiposity modified the association between PA and all-cause mortality and estimated the
It has been reported that there is a difference in drug prescription between males and females. Even after adjustment for multi-morbidity, females tend to use more prescription drugs compared to males. In this study, we wanted to analyse whether the gender difference in drug treatment could be explained by gender-related morbidity.
Although the elderly have a substantially higher drug use than younger patients, even after adjustment for multimorbidity, there is limited knowledge about the elderly's indication for treatment. It is essential for elderly patients to have a well-planned drug therapy. The first step towards a correct and safe drug therapy is to ensure that the patient's drugs have an indication, i.e. correct diag
Objective: The objective was to investigate the association between experience of violation during the past 3 months and self-rated health, taking trust (social capital), economic stress, and country of birth and parents' country of birth into account. Design/setting/participants/measurements: The 2008 public health survey in Skåne is a cross-sectional study with 55% response rate. A random sample
