The influence of exciton-vibrational coupling on the energy level structure, oscillator strength, and relaxation dynamics is investigated for two different excitonic dimer models. As compared with a purely electronic dimer, the inclusion of local vibrational modes within a vibronic dimer gives rise to a complex energy level structure including avoided crossings and changes of the nature of the exc

Background: Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative-hypnotics in older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. Aim: To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age

Popular Abstract in Swedish Intresset för evidens-baserad vård växer snabbt men trots att nya forskningsresultat produceras och publiceras löpande, tar det lång tid innan de får genomslag i den vård som erbjuds patienter och brukare. Det finns beräkningar som talar för att det tar mellan åtta och trettio år innan tillgängliga forskningsresultat har blivit implementerade och börjat användas rutinmäThe aim of this thesis was to investigate and synthesise the knowledge base concerning leadership and its influence on the implementation of evidence-based practice. A further aim was to investigate attitudes and beliefs among politicians, healthcare managers and mental healthcare professionals about the Swedish national guidelines for schizophrenia or schizophrenia-like conditions. Data was colle

ICT has provided the infrastructure to enable easy access to scientific information. Despite this, libraries are suffering from the rising of journal subscriptions. Additionally, the structure of scholarly publications is creating a wasteful situation where publicly funded research is being paid for several times over. University libraries are struggling to deal with these new realities at the sam

We report a case of an axillary abscess with Streptococcus pyogenes complicated by venous thrombosis. Bacterial etiology and typing was obtained by PCR and sequencing of the 16S rRNA and the M-protein genes from abscess material. The bacterium was of M41 serotype and serology indicated that it had expressed pro-coagulant factors.

Large market-driven software companies face new challenges in requirements engineering and management that emerged due to their recent extensive growth. At the same time, the pressure generated by competitors’ and users’ expectations demands being more competitive, creative and flexible to more quickly respond to a rapidly changing market situation. In the pursuit of staying competitive in this co

The first measurements from proton-proton collisions recorded with the ATLAS detector at the LHC are presented. Data were collected in December 2009 using a minimum-bias trigger during collisions at a centre-of-mass energy of 900 GeV. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity, and the relationship between mean transverse momentum and charged-partic

The rise of MEMS and µTAS techniques has created a whole new family of microfluidic devices for a wide range of chemical and biomedical analyses to be performed on small Lab-on-a-chip platforms. The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. External fields and forces are used for these operations, and this

Extreme climatic events such as the El Nino Southern Oscillation profoundly affect many plants and animals, including amphibians, which are strongly negatively affected by drought conditions. How amphibians respond to exceptionally high precipitation as observed in La Nina events, however, remains unclear. We document the correlation between the exceedingly wet 2010-2012 La Nina and community-leve

In this work the sensitivity-increasing effect of single-walled carbon nanotubes (SWCNTs) in amperometric biosensors, depending on their average length distribution, was studied. For this purpose the SWCNTs were oxidatively shortened and subsequently length separated by size exclusion chromatography. Transmission electron micrographs of different fractions of SWCNTs were collected. Diaphorase "wir

Laminar burning velocity of lean hydrogen + air flames at standard conditions is still a debated topic in combustion. The existing burning velocity measurements possess a large spread due to the use of different measurement techniques and data processing approaches. The biggest uncertainty factor in these measurements comes from the necessity to perform extrapolation to the flat flame conditions,

Background: Thrombolysis is a common method in the treatment of lower extremity bypass graft occlusion. The purpose of this study was to investigate the results of thrombolytic therapy in the management of acute bypass graft occlusion and to identify risk factors for technical failure and amputation. Methods: All patients at two tertiary referral centers undergoing thrombolysis for acute graft occ

In this article we look at examples of three predominant kinds of Swedish retail places – the pedestrianised city centre, the neighbourhood centre and the regional shopping mall – all of which play important (winning or losing) roles in contemporary retail development. This investigation is based on an empirical study of the Malmö region (in southern Sweden) and the findings suggest that the diffe

Objectives - Aneurysmal subarachnoid hemorrhage (SAH) is frequently associated with delayed neurological deterioration (DND). Several studies have shown that DND is not always related to vasospasm and ischemia. Experimental and clinical studies have recently documented that it is possible to diagnose and separate cerebral ischemia and mitochondrial dysfunction bedside. The study explores whether c

OBJECTIVE: Describe the clinical course and predictors of change in self-reported outcomes and objectively assessed physical function over time in middle-aged subjects at high risk of, or with knee osteoarthritis (OA). METHODS: We examined 259 subjects (mean age 52.6 [SD 10.4]) at mean 18 and 25 years after previous meniscectomy and 50 population-based age- and sex-matched reference subjects with

Background The safety of long-acting beta(2) agonist (LABA) therapy in asthma remains controversial but no large scale analyses have been published of LABA safety in children. Methods The frequency of asthma-related deaths and hospitalisations following formoterol use in children (4-11 years) and adolescents (12-17 years), compared with non-LABA treatment, was assessed in all AstraZeneca-sponsored

Purpose: We investigated the distribution of cannabinoid receptor subtypes 1 and 2 in the detrusor of different species and studied the effects of cannabinoid receptor 1 and 2 agonists on bladder function. Materials and Methods: Cannabinoid receptor 1 and 2 expression was studied with Western blot and immunohistochemistry in rat, monkey and human detrusors. Co-staining was done for markers of sens

Objectives. Cone beam computed tomography (CBCT) was introduced to Norwegian dental clinics in 2007. The aim of the study was to investigate how dental clinics use this imaging modality, including factors related to workflow and image quality, and to evaluate dentists' opinions on and experiences of using it. Materials and methods. A web-based 59-item questionnaire regarding the clinical use of CB
