Background: Few previous studies have examined the prevalence of giant cell arteritis (GCA). The main objective of this study is to investigate the prevalence of temporal artery positive GCA (TAB+GCA) in southern Sweden.Methods: The study area is the region of Skåne in southern Sweden with a population of 1,3 million inhabitants (36% aged ⩾50 years). To be included in the study, patient should ful

Allometry is a description of organismal growth. Historically, a simple power law has been used most widely to describe the rate of growth in phenotypic traits relative to the rate of growth in overall size. However, the validity of this standard practice has repeatedly been criticized. In an accompanying opinion piece, Packard reanalysed data from a recent study on brain-body ontogenetic allometr

On exposure to stressors, energy is diverted from non-urgent functions towards those important for immediate survival. The degree and nature of reallocation may be affected by the evolutionary history of the animal. The eastern fence lizard (Sceloporus undulatus) coexists in parts of its range with invasive fire ants (Solenopsis invicta), which attack and wound lizards and elevate stress-relevant

Background/Purpose: The aim of this study was to estimate the incidence rate and prevalence of coronary artery diseases (CAD) in patients with temporal artery positive giant cell arteritis (TAB+GCA) from a defined population in southern Sweden, and to describe characteristics of CAD in this sample.Methods: The study cohort consisted of 1202 patients (71.9% women) diagnosed with TAB+GCA between 199

PURPOSE: It is generally believed that large eyelid defects must be repaired using a vascularized flap for 1 lamella, while the other can be a free graft. Recent studies indicate that the pedicle of a tarsoconjunctival flap does not contribute to blood perfusion. The purpose of this study was to explore whether large eyelid defects can be repaired using a free bilamellar eyelid autograft alone.MET

Background: Photoacoustic (PA) imaging is an emerging non-invasive biomedical imaging modality that could potentially be used to determine the borders of basal cell carcinomas (BCC) preoperatively in order to reduce the need for repeated surgery.Methods: Two- and three-dimensional PA images were obtained by scanning BCCs using 59 wavelengths in the range 680-970 nm. Spectral unmixing was performed

Abstrakt Hantverksbryggerinäringen på Gotland är särskilt vital och omtalad från ett nationellt perspektiv, men innehar inte desto mindre en betydande utvecklingspotential. Syftet med denna studie har varit att skapa en nulägesbild över samt identifiera och analysera nyckelaktörer i hantverksölens värdekedja på Gotland. Analysen stödjer sig på en internationell forskningsöversikt, Michael Porter’sAbstract The craft brewery industry on Gotland is particularly vital and well known in Sweden, but nonetheless holds significant development potential. The main purpose of this study has been to construct a situational awareness of the craft beer value chain on Gotland, and to identify its key actors. Furthermore, in order for the craft breweries to become a more prominent part of Gotland's busine

The viability of a renewable electricity system depends on a relatively small share of hydropower storage resources to regulate climate variations and the spatially uneven distribution of renewable energy. By spatio-temporal coordination of hydropower production over larger regions, the energy storage demand will be reduced and contribute to a “virtual” energy storage gain that in Europe was found

Today, acquisition, creation and utilisation of knowledge are the key factors explaining economic development. Firms must constantly employ new knowledge and combine different types of knowledge in their activities to maintain competitiveness. This thesis examines the knowledge economy from two perspectives. The first focuses on the role of geographical proximity for interactive knowledge creation

Den statliga LSS-utredningen tycks inte ta hänsyn till FN:s konvention om rättigheter för personer med funktionsnedsättning, skriver forskarna Anna Bruce och Anna Nilsson.

The design of the stator insulation system for a traction machine used in electric vehicles is a challenge due to the tight requirements set on compact size, high dynamic stresses and a lack of automotive specific insulation standards. A poorly designed stator insulation can lead to safety issues and stator faults. Approximately, 20-30% of faults in traction machines are stator faults. In order to

Grain-128AEAD is a stream cipher supporting authenticated encryptionwith associated data, and it is currently in round 2 of the NIST lightweight cryptostandardization process. In this paper we present and benchmark software implementations of the cipher, targeting constrained processors. The processors chosen arethe 8-bit (AVR) and 16-bit (MSP) processors used in the FELICS-AEAD framework.Both hig

Nickel-based superalloys are typical materials used in components of aeroengines and gas turbine machinery. The strength properties of these alloys at high temperatures are crucial not only to the performance (e.g., power generation efficiency, energy consumption, and greenhouse gas emissions) of aeroengines and industrial gas turbines, but also to machinability during component manufacturing. Thi

This paper analyses and compares a set of case studies on ecosystem services (ES) mapping and assessment with the purpose of formulating lessons learned and recommendations. Fourteen case studies were selected during the EU Horizon 2020 “Coordination and Support Action” ESMERALDA to represent different policy- and decision-making processes throughout the European Union, across a wide range of them

After demonstration of a 23% power conversion efficiency, a high operational stability is the next most important scientific and technological challenge in perovskite solar cells (PSCs). A potential failure mechanism is tied to a bias-induced ion migration, which causes current–voltage hysteresis and a decay in the device performance over time. Herein, alkali salts are shown to mitigate hysteresis

News satire plays with the political in ways that transgress journalistic as well as social and moral boundaries. But the ways in which audiences in different contexts engage with news satire are under-researched, despite the implications of the genre’s role for contemporary citizenship. This article asks how Swedish young adult audiences construct and negotiate news satire’s inherent transgressio
