Understanding the migration ecology of European red admirals Vanessa atalanta using stable hydrogen isotopes

Tracking migratory movement of small animals with variable migration patterns is difficult with standard mark-recapture methods or genetic analysis. We used stable hydrogen isotope (delta D) measurements of wings from European red admirals Vanessa atalanta to study several aspects of this species' migration. In the central part of southern Europe we found large differences in delta D values betwee

Assessment of quality of life in lymphedema patients: validity and reliability of the Swedish version of the Lymphedema Quality of Life Inventory (LQOLI)

The Lymphedema Quality of Life Inventory (LQOLI) is an instrument developed for patients with different types of lymphedema. It contains physical, emotional, social, and practical dimensions and consists of 58 items, each with three sub items concerning life quality, daily life changes, and difficulties of changing and two items concerning life quality in general and in relation to lymphedema. The

Time lags in biodiversity response to farming practice

Agri-environmental schemes have been applied with the goal to mitigate negative effects of agriculture on biodiversity and ecosystem functioning. However, on evaluating the schemes the results have been variable and shown both positive and neutral effects. These variable effects can be attributed to not taking into account important factors affecting the variables at test, such as biodiversity. Th

Birth after Caesarean Section

Popular Abstract in Swedish Förlossning efter kejsarsnitt Kejsarsnitt utgör för närvarande cirka 17% av alla förlossningar i Sverige. En konsekvens av detta är att allt fler kvinnor kommer till specialistmödravården för rådgivning om vilket förlossningssätt som är säkrast vid förlossningen efter ett kejsarsnitt. Två möjligheter finns: planerad vaginal förlossning eller planerat kejsarsnitt. När maBirth after caesarean section (CS) is an issue of growing importance. As a consequence of increasing CS rates, more women having experienced a prior CS will need counselling about preferred second delivery mode. There are two choices: elective repeat caesarean section (ERCS) or trial of labour (TOL). It is well known, that a TOL ending in an emergency CS carries the largest risks for mother and ch

Approximate solution of boundary integral equations for biharmonic problems in non-smooth domains

This paper deals with approximate solutions to integral equations arising in boundary value problems for the biharmonic equation in simply connected piecewise smooth domains. The approximation method considered demonstrates excellent convergence even in the case of boundary conditions discontinuous at corner points. In an application we obtain very accurate approximations for some characteristics

Strong molecular field effects in Auger decay of the potassium 2p core-hole state in molecular KCl, KBr and KI

The K 2p photoionization and subsequent LMM Auger decay have been studied for molecular gas-phase KCl, KBr and KI. The detected manifold spectral structure of the Auger electron spectrum of KCl has been interpreted to originate from strong molecular field effects. This indicates that Auger decay on potassium side of originally very ionic molecules creates inner-shell hole states with a strong mole

On Stern-Gerlach coincidence measurements and their application to Bell's theorem

We analyze a coincidence Stem-Gerlach measurement often discussed in connection with the derivation and illustration of Bell's theorem. The treatment is based on our recent analysis of the original Stern-Gerlach experiment [H. Wennerstrom and P.-O. Westlund, Phys. Chem. Chem. Phys. 14, 1677 (2012)1, where it is concluded that it is necessary to include a spin relaxation process to account for the

Kommunikation, medborgarskap och deltagardemokrati

Popular Abstract in Swedish Det görs en rad försök till demokratisk förnyelse ute i kommunerna. I denna avhandling är det min ambition att analysera ett sådant försök; medborgarutskotten i Helsingborg. De frågeställningar avhandlingen behandlar är 1) vad ligger bakom samtalets betoning i medborgarutskottens deltagardemokratiska aktiviteter? 2) Hur positioneras kommuninvånare som medborgare då medThis is a study of civic communication in a municipal setting. In the south Swedish municipality of Helsingborg operated Civic Committees between 2003 and 2006. The Civic Committees organized different kinds of activities together with the citizens out in the different neighbourhoods of the municipality, such as open meetings, neighbourhood walks, workshops for the future and meetings with specifi

Overcoming the Nyquist Limit in Blood Flow Velocity Estimation

Spectral Doppler ultrasound imaging typically consists of a spectrogram, showing the velocity distribution of the blood, and a brightness (B-) mode image allowing the operator to navigate. It is desirable to have both high spectral and velocity resolution, so that details in the blood flow can be traced, as well as a high B-mode frame rate to allow for tracking of movements and to adjust the posit

Ability of risk scores to predict a low complication risk in patients admitted for suspected acute coronary syndrome.

Background When acute coronary syndrome (ACS) cannot be ruled out, emergency department (ED) patients with chest pain are admitted for in-hospital observation because of the risk of complications such as arrhythmia and acute heart failure. A study was undertaken to compare the ability of three risk prediction models to identify patients at a very low risk of complications. Methods 559 consecutive

Testing the association between social capital and health over time: a family-based design.

The past decade has seen a vast increase in empirical research investigating associations between social capital and health outcomes. Literature reviews reveal 'generalized trust' and 'social participation' to be the most robust of the commonly used social capital proxies, both showing positive association with health outcomes. However, this association could be confounded by unmeasured factors, s

Measurement of the top quark pair production cross section in pp collisions at root s=7 TeV in dilepton final states with ATLAS

A measurement of the production cross section of top quark pairs (t (t) over bar) in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider is reported. Candidate events are selected in the dilepton topology with large missing transverse energy and at least two jets. Using a data sample corresponding to an integrated luminosity of

The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. New strength tests of beams with quadratic holes with rounded corners are presente

Malignant fibrous histiocytoma and fibrosarcoma of bone: a re-assessment in the light of currently employed morphological, immunohistochemical and molecular approaches

Malignant fibrous histiocytoma (MFH) and fibrosarcoma (FS) of bone are rare malignant tumours and contentious entities. Sixty seven cases labelled as bone MFH (57) and bone FS (10) were retrieved from five bone tumour referral centres and reviewed to determine whether recent advances allowed for reclassification and identification of histological subgroups with distinct clinical behaviour. A panel

Differences Between Parkinson's and Huntington's Diseases and Their Role for Prioritization of Stem Cell-Based Treatments

The problems of allocation of scarce resources and priority setting in health care have so far not been much studied in the context of stem cell-based therapeutic applications. If and when competitive cost-effective stem cell-based therapies are available, the problem of priority setting - to whom should stem cell-based therapies be offered and on what grounds - is discussed in this article using

Högre värdeutbyte genom våt- och torrlimning av sågade sidobrädor till egenskapsoptimerade träprodukter för byggmarknaden

The purpose of this project was to investigate the possibilities to manufacture wet-glued laminated beams for load bearing applications from Norway spruce side board lamellae and by that achieve products that are difficult to obtain from the centre yield of a log and also contribute to increased profitability in the sawmill industry. Properties such as shape stability, strength and stiffness of we

On the sensitivity of rotational O2 CARS thermometry to the Herman-Wallis factor

Contributions of vibrationrotation interaction to line intensities of pure rotational coherent anti-Stokes Raman scattering (CARS) of oxygen are here considered in the perspective of what was remarked by us recently for nitrogen. The interaction is conventionally evaluated by means of the so-called HermanWallis (HW) factor, the need of which is conceptually clear but the theoretical expression is
