Objective: To monitor changes in serum concentrations of cartilage oligomeric matrix protein (COMP) during a 24-h period to determine any diurnal variation, and to estimate the half life of COMP in the circulation in patients with symptomatic knee osteoarthritis and in those with rheumatoid arthritis. Methods: Serum samples were drawn every 4 h (7 samples/patient over 24 h) in 10 patients with kne

In this paper an excavation of a croft from the late 19th - early 20th century is presented. The artefact-material material i discussed and compared with information from contomporary written record. The artefact material and the writte documents yielded different kinds of information.

The paper studies the conditions optimum for the proliferation of neural cells at the surface of porous silicon. The results of this study show that the best results are achieved with meso-porous silicon. Geometrical properties of the wafers are also important through charge distribution at mask edges, change of hydrophobicity, degree of oxidation, the release of adhesion proteins from regeneratin

Magnesium chelatase is the first unique enzyme of the bacteriochlorophyll biosynthetic pathway. It consists of three subunits (BchI, BchD, and BchH). Amino acid sequence analysis of the Rhodobacter capsulatus BchH revealed a novel cysteine motif ((CX2CX3CX14C)-C-393) that was found in only six other proteobacteria (CX2CX3CX11-14C). The cysteine motif is likely to coordinate an unprecedented [Fe-S]

Computing systems are becoming more and more complex and powerful. It is nowadays not uncommon to run several server applications on the same physical platform. This gives rise to a need for resource reservation techniques, so that administrators may prioritize some tasks, or customers, over others. This thesis gives an introduction to the Linux kernel 2.6 task scheduler, and scheduling related op

The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide positional andradial velocity measurements with the accuracies needed to produce astereoscopic and kinematic census of about one billion stars throughoutour Galaxy (and into the Local Group), amounting to a

Objective: To test the hypothesis that sub-optimal factors in perinatal care services resulting in perinatal deaths were more common among immigrant mothers from the Horn of Africa, as compared to Swedish mothers. Design: A perinatal audit, comparing cases of perinatal deaths among children of African immigrants residing in Sweden, with a stratified sample of cases among native Swedish women. Se

The integrating properties of the atmospheric boundary layer allow the influence of surface exchange processes on the atmosphere to be quantified and estimates of large-scale fluxes of trace gases and plant isotopic discrimination to be made. Five flights were undertaken over two days in and above the convective boundary layer (CBL) in a vegetated region in central Siberia. Vertical profiles of CO

Objective: Individual-based studies on restricted geographical settings have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may precipitate congestive heart failure. As NSAID use is very extensive, it might increase the occurrence of symptomatic heart failure in the general population. Therefore, in order to study the impact of NSAID utilisation (prescribed and over the counter) on h

Previously it demonstrated that in the absence of Ca2+ entry, evoked secretion occurs neither by membrane depolarization, induction of [Ca2+]i rise, nor by both combined (Ashery, U., Weiss, C., Sela, D., Spira, M. E., and Atlas, D. (1993). Receptors Channels 1:217-220.). These studies designate Ca2+ entry as opposed to [Ca2+]i rise, essential for exocytosis. It led us to propose that the channel a

Traditional 14C urea breath tests are normally not used for younger children because the radiation exposure is unknown. High sensitivity accelerator mass spectrometry and an ultra-low amount (440 Bq) of 14C urea were therefore used both to diagnose Helicobacter pylori (HP) infection in seven children, aged 3–6 years, and to make radiation dose estimates. The activity used was 125 times lower than

The long-term shoreline evolution at Hai Hau Beach in the Red River Delta, Vietnam was simulated using the one-line model GENESIS (Hanson, 1989). Dikes were modelled as seawalls and the sediment continuity equation in GENESIS was modified to take into account the offshore transport of fine-grained sediment. The model performed well, reproducing the magnitude and trend of the long-term shoreline ch

Popular AbstractJag är konstnär! beskriver konstnärskapet i en mindre konstvärld ur ett sociologiskt perspektiv. Den lilla konstvärlden är specifik. Den utmärks av en hög grad av överblickbarhet, igenkännande och osäkerhet. Igenkännandet kan till en del minska den osäkerhet man känner inför vad som är konst och vad som inte är det, och vem som bör tillskrivas en konstnärsroll och vem som bör utdefI am an artist! describes the process of recognition that surrounds being an artist in a local art world; how boundaries are drawn up not only by the artists themselves, but also others in the art world. It also describes the advantages and restrictions of a local art world as far as the artist´s possibilities to be seen, mentioned, judged and distributed, and also the specific general view which
