In other hazardous complex socio-technical systems in society, e.g. nuclear power and aviation, systems-theoretical assumptions are considered a promising way to better understand and manage safety. In this paper, two fundamental approaches to road safety were assessed in the light of a systems theory approach. One approach, is based on a premise where individual road-users are solely responsible
Zeaxanthin is a carotenoid produced by plants and has been associated with protection of the photosynthetic machinery under light stress and, together with lutein, in protection of the central retina of the eye. Zeaxanthin levels in blood plasma have been negatively correlated to the development of AMD (age-related macular degeneration) (Gale et al, 2003). Under normal conditions, plants have a lo
Objectives: Little is known about the biological processes causing aortic aneurysm rupture. Chronic Chlomydophila pneumoniae infection has been suggested as a possible contributing factor to the development and expansion of abdominal aortic aneurysm (AAA). The importance of infection in AAA may be related to the previous pathogen burden, that is, the number of significant titres of antibodies agai
In this prospective nested case-control study we analyzed the circumferential differences in estimated cortical thickness (Est CTh) of the mid femoral neck as a risk factor for osteoporotic hip fractures in elderly women and men. Segmental QCT analysis of the mid femoral neck was applied to assess cortical thickness in anatomical quadrants. The superior region of the femoral neck was a stronger pr
Phospholipid vesicles and supported bilayers have emerged as a promising platform for the development of biorecognition devices. To expand the capabilities of such biochips, it becomes desirable to direct and control the assembly of lipid structures into more sophisticated architectures. As one step toward this goal, we demonstrate the photoregulated desorption of a new class of polymer from lipid
Objective: To assess the value and adverse effects of an ultrasound -guided renal biopsy technique in women with normal and pathotogic pregnancies. Method: Biopsy samples were taken from 36 women with hypertensive disease (28 with pre-eclampsia) and 18 healthy pregnant women using a thin needle and an ultrasound -guided biopsy device. Results: Gtomerutar endotheliosis, a structural change typical
Copolymerization of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with acrylamide (AAm) on the surface of glass plates resulted in the formation of a hydrogel film with porous structure and capable of optical response to the changes in concentration of glucose in the contacting solution. The boronate specific dye, Alizarin Red S (ARS) was incorporated into hydrogel film to increase the sensitivity
The purpose of the present study was to compare symptom load in youth groups treated with three Swedish Blueprint programmes - Functional Family Therapy (FFT), Multisystemic Therapy (MST) and Multidimensional Treatment Foster Care (MTFC) - to see if symptom load matches the intensity of the treatment model as expected. These youth groups were also compared with in- and outpatients from child and a
Parks, remnants of natural habitats and other green areas are important for preserving biodiversity in urban areas. Here, we investigate the relative importance of habitat type and connectivity for butterfly species richness in the city of Malmo, Sweden. Further, we compare species richness and composition in the urban habitats with that in the surrounding agricultural landscape using previously p
Vegetated roofs are becoming a trend in urban design, among others as a tool for city greening, mitigating urban heat island effect, and lowering urban storm runoff. Additionally, pollutant removal within vegetated roofs is often expected; however, it is commonly riot a design feature. This study investigated influence on runoff water quality from two fullscale vegetated roofs (an intensive from J
This study aimed at describing environmental barriers in housing and functional limitations among older community-living people in Sweden, to provide knowledge of housing accessibility problems from a longitudinal perspective, and to shed some light on older people's subjective reflections on housing. Along with a study-specific questionnaire on subjective reflections on housing, the Housing Enabl
The effect of some environmentally relevant factors including salinity, pH, and humic acids on the availability of bisphenol A (BPA) was evaluated by using the negligible-depletion solid-phase microextraction (nd-SPME) biomimetic method. With the variation of salinity (0-500 mM NaCl) and pH (5.0-8.5) of aqueous solutions, the partition coefficients of BPA between the nd-SPME fiber and the aqueous
The steady-state model PROFILE was used to perform Monte Carlo simulations of critical loads of acidity and exceedances of forest soils for 128 sites in the province of Scania, southern Sweden. Statistical tests showed that 100 sites had normal distributed critical loads and exceedances and that the variance of these parameters was statistically equal for all sites. Pooled estimates df the standar
The paper presents results on the use of NOAA AVHRR data for desertification monitoring on a regional-global level. It is based on processing of the GIMMS 8 km global NDVI data set. Time series of annually integrated and standardized annual NDVI anomalies were generated and compared with a corresponding rainfall data set (1981-2003). The regions studied include the Mediterranean basin, the Sahel f
Conditioning lesions of peripheral nerves improve axonal regeneration after injury and involve changes in expression of proteins required for axonal growth. Integrin alpha7beta1 expression in motor and sensory neurons increases following nerve lesions and motor axon regeneration is impaired in alpha7 integrin KO mice (J. Neurosci. 20, 1822-1830). To investigate the role of alpha7beta1 integrin in
Kraft black liquor lignin is a biofuel that is separated from the cellulose during kraft pulping. Improved technology and energy integration in paper mills have led to an energy surplus at many mills. It is therefore of great interest to extract the lignin from the pulp mill and sell it as fuel to replace fossil fuel in other furnaces. The fractionation of kraft black liquor with a total dry matte
An assessment of nutrient sustainability has been done for stands of European beech, Sycamore maple, European oak, Norway spruce, Larch, Grandis fir and Douglas fir at Bjornstorp Estate in southern Sweden. To estimate the nutrient sustainability, mass balance was calculated with respect to Ca, Mg, K, N and P. The release from mineral weathering was calculated using the PROFILE model. The leaching
There still is a need for devices that allow reproducible stimulation of skin areas of the human body. We constructed a stimulation system and tested it by using brief pneumatic stimulation to the right thumb of nine healthy volunteers. BOLD-signals in response to tactile stimulation with frequencies of 1, 3 and 5 Hz were measured using a 3T MRI scanner. The stimulation device consists of syntheti
Sugarcane bagasse-a residue from sugar and ethanol production from sugar cane-is a potential raw material for lignocellulosic ethanol production. This material is high in xylan content. A prerequisite for bioethanol production from bagasse is therefore that xylose is efficiently fermented to ethanol, In the current study, ethanolic fermentation of steam-pretreated sugarcane bagasse was assessed in
