Knowledge on the factors influencing driver speed-behaviour, the relationship between speed and traffic safety and means to influence speed behaviour is systematised. Expert judgements and the high proportion of injury accidents show that improved speed adaptation has the largest safety potential in the following situations: - Road surface-, visibility and weather affected situations (e.g. slipper
The European Prospective Investigation into Cancer and Nutrition (EPIC), which covers a large cohort of half a million men and women from 23 European centres in 10 Western European countries, was designed to study the relationship between diet and the risk of chronic diseases, particularly cancer. Information on usual individual dietary intake was assessed using different validated dietary assessm
We consider the error floor of binary frequency-shift keying (FSK) due to intersymbol interference in time-dispersive mobile radio channels, with a limiter-discriminator-integrator detector. The errors are caused by bursts in the instantaneous frequency. We propose and verify that a nonlinear frequency discriminator can achieve zero error floor for pure FSK by clipping off these bursts. For filter
Self-monitoring of anti-vitamin K treatment by patients with heart valve prostheses is a good alternative to hospital control. Self-monitoring at home allows patients more freedom and opportunity to take greater responsibility for their treatment. Experience from over a years' complication-free treatment of 12 patients is reported in the article.
In October 2004, a free-living Stock Dove (Columba oenas) was found infected with Trichomonas spp. in the district of Soest, North Rhine- Westphalia, Germany. A huge buccal nodular lesion caused an occlusion of the esophagus and an external swelling. The bone of the mandibula was already softened and nearly solubilised. The microscopical examination of a wet swab sample from the carcass detected T
There is growing evidence that chronic wounds show specific temporospatial patterns with respect to the expression of various molecules such as proteinases and their inhibitors. A careful analysis of molecules in the exudate of chronic wounds can be expected to provide useful information regarding events in the underlying tissue. In this connection there is a need for a method applicable to large
This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance. This thesis
Patients with acute asthma attending the emergency room were included in a double-blind, double-dummy and parallel group study to investigate whether a dry powder inhaler (Turbuhaler) can be used in acute asthma. If so, the aim was to establish the potency relationship between a beta 2-agonist (salbutamol) administered by the dry powder inhaler and the pressurized metered-dose inhaler (pMDI). Eigh
In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. These two glycoproteins also bind the complement regulator factor H (FH). Our findings may have implication
We report on an extremely narrow linewidth of a two-dimensional electron-gas photoluminescence in GaAs/AlGaAs quantum wells pumped by ultrasonic vibrations. Below the threshold pumping amplitude, the observed emission line is weak, broad, and undergoes a redshift consistent with the evolution of an electron-hole plasma recombination in the oscillating piezoelectric fields accompanying the sample v
The multi-layer dynamic model SAFE was applied to the forested catchment istebna (Southern Poland), to study recovery from acidification. Environmental pollution in the area has been historically high. The model uses data from an intensive monitoring plot established in 1999 in a spruce stand, which was planted in 1880. Observations showed that the soil was depleted of base cations. The measured b
In order to study the effect of heparin in inducing osteoporosis, 30 female rats were divided in two groups and treated with daily injections of 2 IU heparin/g body weight for 33 and 65 days and compared with the same number of rats acting as controls. The mineral bone mass in the femora of the animals was measured quantitatively. A significant (p less than 0.001) reduction in bone mineral mass wa
The phase behavior and phase structure of the SDS (sodium dodecyl sulfate)-Al(NO3)(3)-H2O system have been studied by combined NMR, SAXS, cryo-TEM and optical polarization microscopy methods at 298 K (25 degreesC) and 311 K (38 degreesC). At 298 K, the micellar solution phase of the binary system SDS-water is not capable of solubilising substantial amount of Al(NO3)(3) salt, and at a certain subst
An investigation of the polar glycosidic fraction from the leaves of myrtle afforded four galloylated nonprenylated phloroglucinol glucosides (3a-d) related to the endoperoxide hormone G3 (4) in terms of structure and biogenesis. Despite their close similarity, significant antibacterial activity was shown only by one of these compounds (3b, gallomyrtucommulone B), while the G3 hormone (4) was inac
Diffusion nuclear magnetic resonance methods traditionally used within colloid and porous media science have recently been applied to the study of microstructures in biological tissue using magnetic resonance imaging. Improved experimental design utilizing multiple diffusion periods or the length of the displacement encoding gradient pulses increases the information content of the diffusion experi
