The permeability of skin to nanoparticles of titanium dioxide (TiO2) used in sunscreens as a reflector of the UV wavelengths of sunlight, was examined using nuclear microscopy techniques. Special attention was given to the permeation characteristics of these nanoparticles across the outer layers of skin, the stratum corneum, in healthy and psoriatic skin condition. Aspects that may influence the i

The objective was to explore the meaning of the phenomenon of problem solving in midwifery when the midwife is faced with a critical situation in the absence of an obstetrician or any physician. A qualitative method was used and critical incidents from delivery wards and/or antenatal clinics in the south of Sweden were narrated by midwives and transcribed verbatim. The interwievs were then analyse

SBU performed a systematic review concerning dyspepsia and gastroesophageal reflux disease (GERD). The review included the perspective of managing patients in primary care. Dyspepsia is a common condition but varies from one geographic area to another. Despite presenting symptoms of dyspepsia, a majority of patients may not have an ulcer diagnosis (non-ulcer dyspepsia [NUD]). For undiagnosed GERD

A survey of the sixty years of the annual selection of the Art of the Swedish Book. Discussed are its aims, workings and criteria, as well as how Swedish a book has had to be, classicism versus modernism in design, trends in typefaces, and the question of actual effects on the trade.

This paper is built on a summary of the findings of a research report, entitled 'European Common Agricultural Policy: An analysis of the main factors affecting its future environmental policy', which aimed to identify and examine the main factors that could influence the development of the environmental policy of the European Union's Common Agricultural Policy (CAP) in the future. After the analys

Strain BOL13 was selected from 18 fungal strains isolated from an oil-spill contaminated site in Oruro, Bolivia. It was identified as a basidiomycete with high homology to Bjerkandera. The fungus degraded 100 mg phenanthrene l(-1) at 0.17 mg l(-1) d(-1) at 30 degrees C at pH 7. During phenanthrene degradation, a maximum manganese peroxidase activity of 100-120 U l(-1) was measured after 10 days of

The catalytic domain of overexpressed protein kinase C (PKC)-delta mediates phorbol 12-myristate 13-acetate (PMA)-induced differentiation or apoptosis in appropriate model cell lines. To define the portions of the catalytic domain that are critical for these isozyme-specific functions, we constructed reciprocal chimeras, PKC-delta/epsilonV5 and -epsilon/deltaV5, by swapping the V5 domains of PKC-d

Between 1980 and 1983, 10 patients received high performance silicone rubber condylar implants for the treatment of isolated degenerative changes of the scaphotrapezial joint. Early clinical and radiographic results (at a mean of 15 months) were excellent. Late follow up of these 10 together with a further 11 patients, however, showed migration of the implant and radiological signs of silicone par

Many Gram-positive bacteria express surface proteins that bind human plasma proteins. These bacterial proteins, and derivatives of them, are of interest for analysis of bacterial pathogenesis and as immunochemical tools. Well-characterized examples include the IgG-binding reagents staphylococcal protein A and streptococcal protein G, and the recently described streptococcal IgA-binding peptide Sap

Popular Abstract in Swedish I denna avhandling studerar jag tvådimensionella geometriska optimeringsproblem. Gemensamt för många praktiskt och teoretiskt intressanta problemställningar inom området är att det är mycket svårt att ta fram optimala lösningar. Det tar helt enkelt alltför lång tid att undersöka alla möjligheter för probleminstanser med stora mängder indata då beräkningstiden växer expoIn this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. The work done in this thesis is a contribution to the research directed at attacking and coping with such NP hard problems in computational geometry
