Popular Abstract in Swedish På Internet initieras en mängd tjänster på många områden. Det är tjänster som på flera sätt ingår i vardagslivet. I avhandlingen undersöks en av dessa tjänster och sätthur den används. Avhandlingen är en studie av e-handel av livsmedel i Sverige i perioden 1998-2003. Det är en period då e-handel bedrivs av de flesta stora aktörer på den svenska livsmedelsmarknaden men äFrom a social constructivist point of view this thesis investigates how e-commerce of grocery develops in the period 1998-2003. The empirical research is done in Sweden. Most Swedish grocery concerns that have had e-commerce and have been forced to shut down as a result of lack of demand. The starting point for this thesis is that technological development is an ongoing process where different act

The silicon vacancy in its neutral charge state (V-Si) has been unambiguously identified in 4H- and 6H-SiC. This was achieved by observation of ligand hyperfine interaction with the four carbon atoms in the nearest-neighbor shell and the twelve silicon atoms in the next-nearest-neighbor shell surrounding the vacancy. The complete hyperfine tensors have been determined for the V-Si(0) center residi

Background: Tibial osteotomy is a treatment for younger and/or physically active patients suffering from uni-compartmental knee osteoarthritis. The open wedge osteotomy by the hemicallotasis technique includes the use of external fixation. The use of external fixation has several advantages, as early mobilization and the opportunity for optimal correction. However, the hemicallotasis technique has

Boron neutron capture therapy is a treatment modality for cancer that depends on the specific uptake of boron by the tumor cells. The infiltrative growth of malignant gliomas requires that boron reach and accumulate in migrating cells outside the margin of the tumor; thus, it is important that the biodistribution of new boron compounds is also studied in the surrounding healthy brain tissue. This

The ability of barley (Hordeum vulgare L.) chlorophyll biosynthetic mutants to regulate the expression of Lhc genes was analyzed by a microarray approach. The Lhc genes are located in the nucleus and encode chlorophyll a/b binding proteins of the light-harvesting complex. The chlorophyll a/b binding proteins are some of the many proteins, which are imported to the chloroplast. It has been suggeste

Human cystatin C variants in which the evolutionarily conserved Gly-11 residue has been replaced by residues with positively charged (Arg), negatively charged (Glu), bulky hydrophobic (Trp), or small (Ser or Ala) side-chains have been produced by site-directed mutagenesis and expression in Escherichia coli. The five variants were isolated and structurally verified. Their inhibitory properties were

The Metabolic Interactive Simulation Tool, MIST, is a software package, running under Microsoft Windows 3.1, which can be used for dynamic simulations, stoichiometric calculations and control analysis of metabolic pathways. The pathways can be of any complexity and are defined by the user in a simple, interactive way. The user-defined enzymatic rate equations can be compiled either by an external

BACKGROUND: Data from several studies support the hypothesis that thrombopoietin (TPO) plasma levels are regulated via circulating platelet (PLT) numbers by binding to PLT TPO receptors (TPO-Rs). In this study, PLT numbers and TPO plasma levels were measured following the transfusion of unmanipulated, sham-saturated, and TPO-R-saturated PLT preparations to provide additional in vivo evidence for t

Growing multiculturalism in Sweden challenges health professionals to provide safe and culturally meaningful care. Differences between the health--disease explanatory models of lay persons and health professionals may lead to communication problems, which ultimately could affect health outcomes. The aim of this study was to explore beliefs about food and health during pregnancy and lactation. Incr

OBJECTIVE: To study the effect of postoperative thyroxine on the volume of the thyroid remnant after lobectomy for benign nontoxic goitre. DESIGN: Prospective, randomised study. SETTING: University hospital, Sweden. SUBJECTS: 50 consecutive patients who underwent lobectomy for benign non-toxic goitre. INTERVENTIONS: Patients were randomised postoperatively to take thyroxine 0.1 mg or placebo daily

Popular Abstract in Swedish När en familjemedlem drabbas av en demenssjukdom påverkas även de övriga familjemedlemmarna på något sätt. Allt mer vård och omsorg flyttar in i hemmen och de närståendes roll och funktion blir mycket centrala. Syftet med denna doktorsavhandling var att undersöka hur närstående till demenssjuka personer mår, och att planera, genomföra och undersöka effekten av en 5-vecOne of the most common diseases occurring in old age groups is dementia. Caring for a relative with dementia poses many challenges for family caregivers and they bear the main responsibility for the persons with dementia living at home. The overall aim of this thesis, which consists of five community-based studies, was to explore experiences of burden and satisfaction among family caregivers (FC)

BACKGROUND: The characteristic feature of Goodpasture disease is the occurrence of an autoantibody response to the noncollagenous domain of the alpha3 chain of type IV collagen [alpha3(IV)NC1] in the alveolar and glomerular basement membrane. These antibodies are associated with the development of a rapidly progressive glomerulonephritis, with or without lung hemorrhage, whereas autoantibodies spe

This article is based on a content analysis of intellectual capital (IC) in annual reports from 1998 to 2002. The aim of the study was to compare the content of voluntary information on IC in the corporate annual reports covering a period of 4 years. The results from the study, based on 15 Swedish companies in the retail sector, show that for the year 2002 the information on human capital in the a
