Background: The wrist region is one of the most complex joints of the human body. It is prone to deformity and functional impairment in juvenile idiopathic arthritis (JIA), and is difficult to examine clinically. The aim of this study was to evaluate the role of ultrasonography (US) with Doppler in diagnosis of synovitis, guidance of steroid injections, and follow-up examinations of the wrist in J

In Public Reading in Early Christianity: Lectors, Manuscripts, and Sound in the Oral Delivery of John 1-4 Dan Nässelqvist investigates the oral delivery of New Testament writings in early Christian communities of the first two centuries C.E. He examines the role of lectors and public reading in the Greek and Roman world as well as in early Christianity. Nässelqvist introduces a method of sound ana

We used an extensive dataset (1220 vegetation plots of 1 m(2)) to study vegetation gradients and fine-scale plant diversity in dry calcareous grasslands (including alvar grasslands) in the Baltic Sea region. The study area covers the entire European distributional range of alvar habitats: Sweden (Oland, Gotland, Gotaland), Estonia (Saaremaa, Hiiumaa, north Estonia, west Estonia), and western Russi

Background: The sporulation of aerial hyphae of Streptomyces coelicolor is a complex developmental process. Only a limited number of the genes involved in this intriguing morphological differentiation programme are known, including some key regulatory genes. The aim of this study was to expand our knowledge of the gene repertoire involved in S. coelicolor sporulation. Results: We report a DNA micr

Cell proliferation affects both cellular geometry and topology in a growing tissue, and hence rules for cell division are key to understanding multicellular development. Epithelial cell layers have for long times been used to investigate how cell proliferation leads to tissue-scale properties, including organism-independent distributions of cell areas and number of neighbors. We use a cell-based t

Asthma is a chronic respiratory disorder affecting an estimated 300 million people worldwide. Most patients with asthma can be controlled with bronchodilators and low to moderate dose inhaled corticosteroids. However, an estimated 5-10% of the population presents a more troublesome disease, often referred to as severe asthma. The aim of present thesis was to study the relationship between histopat

Behavioural variant frontotemporal dementia (bvFTD) is associated with changes in dorsal striatal parts of the basal ganglia (caudate nucleus and putamen), related to dysfunction in the cortico-striato-thalamic circuits which help mediate executive and motor functions. We aimed to determine whether the size and shape of striatal structures correlated with diagnosis of bvFTD, and measures of clinic

Experimental observations and numerical simulation were conducted to study the flame characteristics and flame stabilization mechanism in a supersonic combustor with hydrogen injection upstream of cavity flame holders. OH radical distribution of the reacting flowfield was obtained using OH spontaneous emission and OH-PLIF (planar laser-induced fluorescence). The supersonic combustion flowfield wit

The Swedish Parliament has voted for massive expansion of wind power within the next decade. As in many other countries, the establishment of new wind farms has aroused local opposition. This paper contributes to the literature using a qualitative methodology to analyse attitudes towards wind power. In 2007, we carried out in-depth interviews with 40 stakeholders concerned with two planned nearsho

In this paper we investigate the possibility of multiple HAP coverage of a common cell area. In particular we study the uplink system performance since it is considered as a worst case scenario. In order to obtain further enhancement (interference mitigation) we also apply space-time diversity techniques, such as Single-Input Multiple-Output (SIMO) receive diversity or Multiple-Input Multiple-Outp

The response of electric devices to an applied thermal gradient has, so far, been studied almost exclusively in two-terminal devices. Here we present measurements of the response to a thermal bias of a four-terminal, quasiballistic junction with a central scattering site. We find a novel transverse thermovoltage measured across isothermal contacts. Using a multiterminal scattering model extended t

Waldenstrom's macroglobulinemia (WM) is associated with a precursor condition, monoclonal gammopathy of undetermined significance (MGUS) of immunoglobulin-M (IgM) type. The etiology of these conditions is unknown. Recent studies at the population level have provided new data regarding familial aggregation of these disorders and other B-cell malignancies. Studies of familial clusters of WM have dem

We show that the geometry of the Wilson lines, entering the operator definition of the transverse-momentum dependent parton distributions and that of the soft factor, follows from the kinematics of the underlying physical process in conjunction with the gauge invariance of the QCD Lagrangian. We demonstrate our method in terms of concrete examples and determine the paths of the associated Wilson l

This paper presents the results of an experimental study to investigate the behaviour of structurally damaged full-scale reinforced concrete beams retrofitted with CFRP laminates in shear or in flexure. The main variables considered were the internal reinforcement ratio, position of retrofitting and the length of CFRP. The experimental results, generally, indicate that beams retrofitted in shear a

Thermodynamic parameters are presented here illustrating the effects caused by the two anticancer active metal complexes cisplatin and oxaliplatin after introduction into four closely related RNA and DNA duplexes. The duplexes used are blunt end, fully complementary 15-mer duplexes with a centrally located either GG- or GNG (here: N = T or U) binding site. For all duplexes, a common trend of reduc

In this study, we evaluated 10 months data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden), Uto (upwind, Finland), and Preila (downwind, Lithuania). Differences in aerosol particle number size distributions between the upwind and downwind stations during situations
