We present experiments with a rolling multichannel microphone array where measurements can be taken continuously while moving. Leaky air-coupled surface waves are measured with ordinary non-directional audio microphones. Results show that microphones can be successfully used to produce a realistic phase velocity spectrum even while moving along the surface. The paper presents some theoretical back

Popular Abstract in Swedish Märkesorientering är ett nytt förhållningssätt till varumärken. Inom företag som Nestlé, Pharmacia & Upjohn Nicorette och Volvo utgör varumärkena det nav kring vilket strategierna kretsar. Varumärkesfrågor behandlas inte längre som taktiska spörsmål utan är ledningsfrågor. Målsättningen inom märkesorienterade företag är ytterst att skapa, utveckla och skydda varumärThe aim of this study was to examine how an organisation’s approach to brands can, in the building up of a brand competence, prevent trademark degeneration and develop and protect brands as strategic resources. A line of argument is put forward for adopting a new corporate approach (mind-set) to brands. The starting-point is the concept of trademark degeneration (genericness), which is both the ke

An appropriate animal model is essential to study Helicobacter pylori infection. The aim of this study was to investigate if H. pylori can colonise the guinea-pig stomach and whether the infection causes gastritis and a serological response similar to that observed in man. Guinea-pigs were infected either with fresh H. pylori isolates from human gastric biopsies or with a guinea-pig passaged strai

Intranasal administration of peptide Acl-9[4Y], based on the N-terminal epitope of myelin basic protein, can induce CD4(+) T cell tolerance, and suppress experimental autoimmune encephalomyelitis induction. The peptide-induced regulatory T (PI-T-Reg) cells failed to produce IL-2, but expressed IL-10 in response to Ag and could suppress naive T cell responses in vitro. Analysis of Jak-STAT signalin

A total of 309 Helicobacter pylori isolates from 18 different countries were analyzed with a previously developed lectin typing system. The system was developed by using a proteolytic pretreatment to enhance the carbohydrate fraction of the sample. Four lectins from Ulex europaeus, Lotus tetragonolobus, Erythrina cristigali, and Triticum vulgaris were used to type the strains. The lectins were cho

Reduced capacity to produce ROS increases the severity of T cell-dependent arthritis in both mice and rats with polymorphisms in neutrophil cytosolic factor 1 (Ncf1) (p47phox). Since T cells cannot exert oxidative burst, we hypothesized that T cell responsiveness is downregulated by ROS produced by APCs. Macrophages have the highest burst capacity among APCs, so to study the effect of macrophage R

The stopping powers in silicon of heavy ions, with atomic numbers ranging from 4 to 29, have been determined using a time-of-flight elastic recoil detection analysis (TOF ERDA) set-up. In transmission geometry, the energy loss of heavy elastic recoils in the self-supporting silicon foil of known thickness is measured over a continuous range of recoil energies using time-of-flight (TOF) spectrometr

A misaligned stretcher or compressor in a chirped pulse amplification laser introduces residual angular dispersion into the beam, resulting in temporal distortion of the pulse. We demonstrate that an imaging spectrograph is capable for Measuring the angular dispersion of a laser beam by an accuracy of 0.2 murad/min. Using this technique, the analytical expressions of residual angular dispersion of

The etiology of exercise-induced rib stress fractures (RSFs) in elite rowers is unclear. The purpose of the study was to investigate thoracic muscle activity, movement patterns and muscle strength in elite rowers. Electromyographic (EMG) and 2-D video analysis were performed during ergometer rowing, and isokinetic muscle strength was measured in seven national team rowers with a history of RSF and

Popular Abstract in Swedish Framväxten av affärssystem under 1990 talet är en av de mest betydelsefulla utvecklingarna inom verksamhetsstödjande informationssystem. Affärssystem karaktäriseras av omfattande branschtäckning, stor funktionalitet, generisk lösning, processorientering, integrerad lösning och centralt dataformat, som tillsammans gör affärssystem kanske till den hittills mest komplexa oEnterprise Systems are one of the most important developments in corporate information systems during the last decade. These integrated information systems are characterized by a number of features which include a very broad scope and functionality, as well as being generic, master data, and business-process orientated. Together, these features make Enterprise Systems unique vis-à-vis other inform

Models of Parkinson's disease (PD) based on selective neuronal death have been used to study pathogenic mechanisms underlying nigral cell death and in some instances to develop symptomatic therapies. For validation of putative neuroprotectants, a model is desirable in which the events leading to neurodegeneration replicate those occurring in the disease. We developed a human in vitro model of PD b

AIMS: This study sets out to investigate direct care staff's views of their need for support, supervision, and training in their practice in day care settings when supporting daily occupations among developmentally disabled persons. BACKGROUND: The first line staff are considered as having a prominent role in the successful delivery of service. METHODS: Three municipalities, one urban and two rura

Context: Protein profiling of diabetic tissues could provide useful biomarkers for early diagnosis, therapeutic targets, and disease response markers. Cultured fibroblasts are a useful in vitro model for proteome analysis and study of the molecular mechanisms involved in diabetes. Objective: The objective of the study was to isolate and characterize the proteins of cultured fibroblasts, obtained b

Transgenic mice were generated expressing NK1.1, an NK cell-associated receptor, under control of the human CD2 promoter. Unexpectedly, one of the founder lines, Tg66, showed a marked defect in thymic development characterized by disorganized architecture and small size. Mapping of the transgene insertion by fluorescence in situ hybridization revealed integration in chromosome 2, band G. Already f

The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world's most powerful neutron source to be built in Lund, Sweden. The ESS will use a linear accelerator which will deliver protons with 5 MW of power to the target at 2.5 GeV with a nominal current of 50 mA. The superconducting part of the linac consists of over 150

The results from bending tests on 107 laminated, green-glued, beams manufactured from Norway spruce side boards are presented. The beams were made by face gluing 21-25 mm thick boards using a commercial one-component moisture curing polyurethane adhesive. In addition to the bending test results, results from shape stability measurements after climatic cycling and bond line strength and durabili

The early host response to an infection is dependent on an efficient innate immune system. The human contact system once activated at a bacterial surface results in the induction of proinflammatory reactions and the release of antimicrobial peptides, However, under severe conditions its systemic activation A may evoke the generation of pathologic levels of kinins and a consumption of contact facto
