Studies of natural radiative lifetimes and hyperfine structure have been performed for group IIA and IIIA atoms. Different laser spectroscopic techniques such as PUMOLS, time-resolved laser spectroscopy, using transient recorder, and collimated atomic-beam experiments have been used. These methods employ cw or pulsed dye laser systems. The lifetime measurements revealed several cases in barium and
Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing c
On 14 November 2012 the new EU-directive 2012/27/EU was published in the Official Journal of the European Union. In the directive there is a requirement, among others, for individual consumption meters for heat and hot water to be installed by 31 December 2016 in multi-apartment buildings. Individual consumption meters had earlier been found to create a saving behavior due to the tenants being cha
We studied bacterial and fungal colonization of submerged plant litter, using a known Si-accumulator (Equisetum arvense), in experimental microcosms during one month. We specifically addressed the microbial decomposer role concerning biogenic silica (bSiO2) dissolution from the degrading litter. To vary the rates and level of microbial colonization, the litter was combined with a range of mineral
We present a Bayesian ideal observer model that estimates observer translation and rotation from optic flow and an extra-retinal eye movement signal. The model assumes a rigid environment and noise in velocity measurements, and that eye movement provides a probabilistic cue for rotation. The model can simulate human heading perception across a range of conditions, including: translation with simul
In the coming renewables-based energy transition, global electricity consumption is expected to double by 2050, entailing widespread end-use electrification, with significant impacts on energy efficiency. We develop a long-run, worldwide societal exergy analysis focused on electricity. Our 1900–2017 electricity world database contains the energy carriers used in electricity production, final end-u
Comparing 3D neutron and X-ray microtomography (NCT and XCT) results of fully pyrolyzed and pristine samples, we observed that the contrast in the neutron images increased for the carbonized samples, suggesting that H would be concentrated at the surface of the carbonized material structure.
OBJECTIVE: Previous studies have suggested that transportation noise may increase risk for breast cancer, but existing literature is scarce and inconclusive. We aimed to investigate associations between road traffic and railway noise and risk for breast cancer across the entire Danish female population.METHODS: For all 2.8 million residential addresses across Denmark, we modelled road and railway
The incredible thing with blood stem cells, also known as hematopoietic stem cells (HSC), is that they can restore normal hematopoiesis in patients that need a new blood system. Since a prerequisite for successful transplantation is immune compatibility, it requires large donor registries to find a suitable match for a recipient. Unfortunately, there is still a shortage of immune-compatible donors
A radioactive fallout following a nuclear accident can result in contamination of large areas of land. In order to protect human health against ionizing radiation, large-scale decontamination that includes multiple sets of clean-up measures may be necessary. Sweden lacks national experience of this type of large-scale decontamination. There are thus great uncertainties in the effect of such a deco
The European Union (EU) Water Framework Directive is of paramount importance for water management. According to the legal text, coordination with other directives like the Floods Directive is imperative and motivated by potential synergy effects. In this paper, the degree to which such coordination is achieved is evaluated for five Nordic and Baltic countries. The evaluation is based on legal docu
This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. First, the stray-light suppression method Periodic Shadowing (PS) is implemented in an experimental setup with a high-power high repetition rate laser syste
As the demand for sustainable and efficient energy systems continues to grow, integrated energy solutions have sparked interest in materials that combine multiple functionalities within a single structure. Rather than serving a single purpose, such materials could store energy, catalyse chemical reactions, and even exhibit optical changes, enabling novel applications in smart devices and material
This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic
Far beyond its innocence, children and child welfare initiatives have emerged as powerful symbols in Indonesian political campaigns. This research focuses on Joko Widodo and Prabowo Subianto, showing how their use of initiatives like Smart Card and Free Lunch Program projected legitimacy and garnered votes during the 2014, 2019, and 2024 elections. It uses two main methods: reflexive thematic anal
This study examines how AI for minors is framed by AI companies and constructed in public discourse in China and the United States. Using Rhetorical Arena Theory and framing theory, the study analyses corporate communication from four AI platforms (ChatGPT, Gemini, Grok, and Doubao) together with public discourse materials, including mainstream media, NGO reports, and online commentary. Reflexive
To this day, the question of what factors drive economic development and catching-up remains deeply controversial in growth literature. The concept of social capability provides a useful framework to investigate the relationship of the parallel processes of transformation, inclusion, autonomy and accountability with economic performance. Nevertheless, there are few attempts to quantify social capa
Mediated mega-events are essentially projects of belonging: about imagining communities and about creating attachment to such collective selves. However, events like the Olympic Games are not only an opportunity for states to reinforce official constructions of belonging but can also be sites for the articulation and dissemination of contesting identity narratives.
