Kvinnan från Österöd - ett tidigmesolitiskt skelett från Bohuslän
In this paper we describe the find of an early Mesolithic skeleton from Österöd, Bro parish, in central Bohuslän. The skeleton was originally found in 1903 by diggers in a shell bank, but was only recovered in 1933 by Johan Alin. In 2007, 14C analysis of a tooth produced the date 9025±65 BP uncalibrated, making the skeleton one of the oldest known from Scandinavia. Osteological determinations show
Does the season at symptom onset influence the long-term severity of radiographic joint destruction in rheumatoid arthritis?
Complement Cascade in Systemic Lupus Erythematosus Analyses of the Three Activation Pathways
The complement (C') cascade is an important part of the innate immunity. It acts through three major pathways: classical (CP), alternative (AP) and mannose-binding-lectin (MP). C' reduction is a key feature in systemic lupus erythematosus (SLE), for its pathogenesis and for disease relapse. The aims of our study are to correlate C' variations with disease activity and verify the presence of C' def
Framtidens gudstjänst? : Kyrkohandboksförslaget granskat
This volume 89 of the Yearbook for Swedish Liturgical Life is dedicated to the 2013 proposal for a new Kyrkohandbok for the Church of Sweden. It includes articles by Thomas Appelqvist, Eva Hættner Aurelius, Ingrid Dahlström, Ragnar Holte, Frank C. Senn, Bernice Sundkvist and Anna Maria Böckerman. All articles are in Swedish with summary in English except for Frank Senn's article, which is in Engli
Vibrational vs. electronic coherences in 2D spectrum of molecular systems
Two-dimensional spectroscopy has recently revealed the oscillatory behavior of the excitation dynamics of molecular systems. However, in the majority of cases there is considerable debate over what is actually being observed: excitonic or vibrational wavepacket motion or evidence of quantum transport. In this letter we present a method for distinguishing between vibrational and excitonic wavepacke

MHC class II B diversity in blue tits: a preliminary study
In this study, we partly characterize major histocompatibility complex (MHC) class II B in the blue tit (Cyanistes caeruleus). A total of 22 individuals from three different European locations: Spain, The Netherlands, and Sweden were screened for MHC allelic diversity. The MHC genes were investigated using both PCR-based methods and unamplified genomic DNA with restriction fragment length polymorp
Antimicrobial sensitivity-A natural resource to be protected by a Pigouvian tax?
Since their discovery more than 70 years ago antibiotic drugs have been efficient tools for treating bacterial infections, and their use has reduced the number of fatalities and the suffering from bacterial diseases. However, the use of antibiotics may lead to resistance to the same or other antibiotics. The risk of resistance appears to be larger in veterinary medicine, since antibiotics have bee
Intervention randomized controlled trials involving wrist and shoulder arthroscopy: a systematic review
Background: Although arthroscopy of upper extremity joints was initially a diagnostic tool, it is increasingly used for therapeutic interventions. Randomized controlled trials (RCTs) are considered the gold standard for assessing treatment efficacy. We aimed to review the literature for intervention RCTs involving wrist and shoulder arthroscopy. Methods: We performed a systematic review for RCTs i

Ecological Dynamics Across the Arctic Associated with Recent Climate Change
At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether
Antibodies Covalently Immobilized on Actin Filaments for Fast Myosin Driven Analyte Transport
Biosensors would benefit from further miniaturization, increased detection rate and independence from external pumps and other bulky equipment. Whereas transportation systems built around molecular motors and cytoskeletal filaments hold significant promise in the latter regard, recent proof-of-principle devices based on the microtubule-kinesin motor system have not matched the speed of existing me
Nano particles as the primary cause for long-term sunlight suppression at high southern latitudes following the Chicxulub impact - evidence from ejecta deposits in Belize and Mexico
Life on Earth was sharply disrupted 66 Ma ago as an asteroid hit the sea-floor in what is today Yucatan Peninsula, Mexico. Approximately 600 km(3) of sedimentary rock were vapourized, ejected into the atmosphere and subsequently deposited globally as an ejecta apron and fallout layer. Proximal ejecta deposits occur in Belize and southern Mexico where the so called Albion island spheroid bed is sup
Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials
Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. Nowadays, the cement industry produces cements with increasing amounts of supplementary cementitious materials (SCMs) to
Permanent Distal Occlusion of Middle Cerebral Artery in Rat Causes Local Increased ETB, 5-HT1B and AT(1) Receptor-Mediated Contractility Downstream of Occlusion
Background/Aims: In response to experimental stroke, a characteristic functional and expressional upregulation of contractile G-protein-coupled receptors has been uncovered in the affected cerebral vasculature; however, the mechanism initiating this phenomenon remains unknown. Methods: Using a model of permanent distal occlusion of rat middle cerebral arteries, we investigated whether there was a

Theory of attosecond delays in laser-assisted photoionization
We study the temporal aspects of laser-assisted extreme ultraviolet (XUV) photoionization using attosecond pulses of harmonic radiation. The aim of this paper is to establish the general form of the phase of the relevant transition amplitudes and to make the connection with the time-delays that have been recently measured in experiments. We find that the overall phase contains two distinct types o
High tibial osteotomy in Sweden, 1998-2007 A population-based study of the use and rate of revision to knee arthroplasty
Background and purpose Most studies on high tibial osteotomies (HTOs) have been hospital-based and have included a limited number of patients. We evaluated the use and outcome-expressed as rate of revision to knee arthroplasty-of HTO performed in Sweden with 9 million inhabitants, 1998-2007. Patients and methods 3, 161 HTO procedures on patients 30 years or older (69% men) who were operated on for
Size-dependent evolution of electronic structure in neutral Pb clusters-As seen by synchrotron-based X-ray photoelectron spectroscopy
Neutral Pb clusters in the size range from a few tens of atoms up to similar to 100 atoms are studied using synchrotron-based photoelectron spectroscopy. The electronic structure is seen to differ increasingly from that of the solid when the cluster size decreases. The valence band narrows gradually - down to about one fifth of the solid-state band width at the smallest size of few tens of atoms.
