Along with an increasingly globalized business environment and a strongly held corporate belief that the world can be rationally managed, the last two decades have witnessed a growing demand for normative models dealing with cross-cultural management issues. This trend has allowed cross-cultural management to establish itself as a significant research field, with much of the initial inspiration co
Car-to-car and car-to-infrastructure (henceforth called C2X) communications are constantly gaining importance for road-safety and other applications. In order to design efficient C2X systems, an understanding of realistic C2X propagation channels is required, but currently, only few measurements have been published. This paper presents a description of an extensive measurement campaign recently co
The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing ex
Antisymmetric magneto-resistance anomalies generated by a reversal of the magnetization are studied in a number of GaMnAs/InGaAs layers with out-of-plane (easy axis) magnetization. The anomalies occur independent of the magnetic field orientation. This shows, that once a magnetic domain with reversed magnetization is nucleated, simply the presence of the domain wall between the longitudinal contac
Popular Abstract in Swedish Förmaksflimmer är den vanligaste rytmrubbningen i hjärtat. Man beräknar att 1-2% av befolkningen har förmaksflimmer. Förmaksflimmer blir vanligare med stigande ålder. Bland personer äldre än 75 år har 5-10% förmaksflimmer. Var fjärde person över 40 år riskerar att drabbas av förmaksflimmer någon gång i livet. Förmaksflimmer ger bl.a. en ökad risk för blodproppar och strAtrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the general population, and a major cause of morbidity and mortality. Low-grade inflammation, erythrocyte volume variation, and subclinical atherosclerosis have repeatedly been associated with cardiovascular disease, but it remains unclear whether these risk factors are also associated with incident AF. This thesis is bas
Assays detecting antigen (Ag)-specific T-cell responses in immune-mediated processes are increasingly employed to understand disease pathogenesis and "immune staging". The quantity and quality of starting peripheral blood mononuclear cell (PBMC) preparations are important factors in the performance of such assays. We therefore compared final PBMC yield and function by modifying parameters at the b
Adenovirus-based (Ad) vectors are used widely for experimental gene transfer to the CNS. Ad transduce many cell types including postmitotic neurons. However, their use for, CNS gene transfer is limited due to the host immune response elicited. Furthermore, the extensive distribution of the primary cellular receptor for Ad, the coxsackievirus and adenovirus receptor (CAR), allows adenoviral vectors
he state-of-the-art understanding of activated sludge processes as summarized in activated sludge models (ASMs) predicts an instantaneous increase in the biomass activity (which is measured, e.g., by the corresponding respiration rate OUR, NUR, etc.) under sudden substrate concentration changes. Experimental data (e.g., short-term batch respiration experiments under aerobic or anoxic conditions) c
In a recent paper,(1) we investigated how the interaction between two adsorbing surfaces in a polymer solution responds to changes of the intrinsic stiffness of the polymer chains. We demonstrated that as the chain rigidity is increased, starting from the fully flexible limit, a free energy barrier develops. In this work, we shall continue our studies of semiflexible polymers but focus on the othe
The aim of the present study was to gain information about adrenergic-, cholinergic- and nonadrenergic, non-cholinergic (NANC)- transmitter systems/mediators in the rat vagina, and to characterize its smooth muscles functionally. Tissue sections from vagina of Sprague Dawley rats were immunolabelled with antibodies against protein gene product 9.5 (PGP), synaptophysin (Syn), tyrosine hydroxylase (
We have investigated spin accumulation in Ni/Au/Ni single-electron transistors assembled by atomic force microscopy. The fabrication technique is unique in that unconventional hybrid devices can be realized with unprecedented control, including real-time tunable tunnel resistances. A grid of Au disks, 30 nm in diameter and 30 nm thick, is prepared on a SiO2 surface by conventional e-beam writing.
The error in smoke transport models have mainly been analyzed with qualitative approaches till date. The results make it difficult to perform a quantitative assessment of the model error in fire safety design applications. Even if a model has a substantial model error, it can be a very useful tool, as long as the designer is aware of the errors and the uncertainties in the predictions. This paper
The Earths magnetic field and celestial cues provide animals with compass information during migration.Inherited magnetic compass courses are selected based on the angle of inclination, making itdifficult to orient in the near vertical fields found at high geomagnetic latitudes. Orientation cage experimentswere performed at different sites in high Arctic Canada with adult and young white-crownedsp
Fourth-generation (4G) systems are expected to support data rates of the order of 100 Mb/s in the outdoor environment and 1 Gb/s in the indoor/stationary environment. In order to support such large payloads, the radio physical layer must employ receiver algorithms that provide a significant increase in spectrum efficiency (and, hence, capacity) over current wireless systems. Recently, an explosion
The gas-to-aqueous solution shifts of the O-17 and C-13 NMR isotropic shielding constants for the carbonyl chromophore in formaldehyde and acetone are investigated. For the condensed-phase problem, we use the hybrid density functional theory/molecular mechanics approach in combination with a statistical averaging over an appropriate number of solute-solvent configurations extracted from classical
The recent finding that the formation of staphylococcal enterotoxins in food is very different from that in cultures of pure Staphylococcus aureus sheds new light on, and brings into question, traditional microbial risk assessment methods based on planktonic liquid cultures. In fact, most bacteria in food appear to be associated with surfaces or tissues in various ways, and interaction with other
