This article contributes to discourse-oriented, information-seeking research by showing how discourses, from a neopragmatist perspective, can be explored as tools that people employ when they actively engage in information practices in varied social contexts. A study of nurses and the nursing profession in Sweden is used as an empirical example of such a context, which is in the article understood
We report on experimental absolute oscillator strengths for 18 UV lines of Ru II, obtained by combining laser-induced fluorescence measurements of radiative lifetimes and branching fractions from line intensities in a calibrated Fourier-transform spectrum. HST/GHRS observations of the spectrum of the sharp-lined B star chi Lupi contain six of these lines, for which ''astrophysical'' relative f-val
"Lethal midline granuloma" of the upper airways generally encompasses T-cell lymphoma and Wegener's granulomatosis in Western populations. Treatment and outcome for each is different, but their pathological distinction may not always be possible on routine biopsy specimens. Within a defined population between 1947 and 1994, we found 12 cases of primary sinonasal T-cell lymphoma, all with a CD20-,
Creep and shrinkage are two major problems to be discussed in concrete design. Basic creep is studied during constant loading, temperature and moisture conditions, i.e. no exchange of moisture takes place to or from the specimen during the test period. In this paper an experimental and numerical study of basic creep of High Performance Concrete (HPC) is outlined. For this purpose cylinders and cub
Popular Abstract in Swedish Nästan en miljon nya fall av magsäckscancer diagnostiseras årligen världen över. Även om frekvensen har fallit dramatiskt de senaste åren så är magsäckscancern fortfarande den näst vanligaste orsaken till död i cancer sett ur ett världsperspektiv. Den geografiska variationen av denna cancertyp är anmärkningsvärd med den högsta förekomsten i asiatiska länder såsom Japan,Nearly one million new cases of gastric cancer are diagnosed annually throughout the world. Even though the incidence has fallen dramatically in recent decades, this disease is still the second leading cause of cancer death in a global perspective. The geographic distribution of gastric cancer varies markedly, with the highest rates in Asian countries such as Japan, Korea, and China. This variatio
The extent of degradation of the fungal biomass in forest soil during laboratory incubation was investigated as a measure of ectomycorrhizal (EM) biomass. The method simulates the disappearance of fungal mycelium after root trenching, where the EM fungi, deprived of its energy source (the tree), will start to die off. Incubating a forest humus soil at 25 C resulted in a decrease in the relative pr
We have previously reported that the heparan sulfate-priming glycoside 2-(6-hydroxynaphthyl)-ß-D-xylopyranoside selectively inhibits growth of transformed or tumor-derived cells. To investigate the specificity of this xyloside various analogs were synthesized and tested in vitro. Selective growth inhibition was dependent on the presence of a free 6-hydroxyl in the aglycon. Because cells deficient
A novel method has been developed for acquiring the correct alignment of a query sequence against remotely homologous proteins by extracting structural information from profiles of multiple structure alignment. A systematic search algorithm combined with a group of score functions based on sequence information and structural information has been introduced in this procedure. A limited number of to
The entire population of magmatic oscillatory zoned zircons in a migmatitic granite from the Tjarnesjo intrusion, southwest Sweden, reveal fine-scale brittle fracturing. The oscillatory zoned fragments are rotated but not dispersed. Fractures between individual fragments are sealed by newly formed CL-bright zircon. Hydraulic fracturing is the most probable mechanism. The internal structure of frac
Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors difficult. This thesis has applied microarray-based gene expression and copy-number profiling to STS
Purpose: Autonomous bladder activity can take the form of localized micromotions (MMs), suggesting that the detrusor may be arranged into component modules, of which each is capable of contracting autonomously. We examined MMs in isolated whole rat bladder and the effects of partial bladder outlet obstruction as a model of detrusor overactivity (DO) to ascertain whether altered modular activity co
