The aim of this study was to analyze the composition of sway in adults and "healthy" elderly people and to evaluate the influence of vibration sensation and asymmetric vestibular function on the sway pattern. Ten adults with a mean age of 37.5 years and 40 healthy senior citizens with a mean age of 74.6 years living independently in the community were studied. Vibration-induced body sway was measu

PURPOSE: To determine the relevance of popliteal dilatations, knowledge of the normal popliteal artery diameter is essential. This study investigates the diameter of the popliteal artery in healthy males and females. METHODS: We measured the diameter of the popliteal artery in 121 healthy volunteers (59 males and 62 females), ages 8 to 81, with echo-tracking B-mode ultrasonography. We analyzed the

The research project aims at investigating the potential of new concrete materials technology (high performance concrete, HPC and self-compacting concete, SCC) for competitive design, production and function of structural frames of cast in-situ concrete in house building.

beta 2-microglobulin (beta 2m) was found to interact with many group A streptococcal strains. The interaction appeared to require multipoint attachment, since monomeric beta 2m in solution showed no binding, whereas both beta 2m monomers bound to liposomes, and beta 2m in aggregates showed affinity for the bacteria. Aggregated HLA antigens (-A, -B and -C) and aggregated beta 2m exhibited the same

The effective diffusion coefficient of ethanol in a 4 %(w/v) agarose gel at 25-degrees-C was measured using a diaphragm diffusion cell. The reproducibility was very good; a standard deviation of only 2% was obtained. The mean value (9.5 x 10(-6) cm2/s) agreed well with available theory and previous investigations.

Aunque los conocidos modelos de la escuela de Tartu contraponen la Cultura a la Naturaleza, realmente se refieren a la relación entre las culturas, una de las cuales se concibe como si fuera naturaleza. La inspiración para el concepto tardío de Lotman de la semiosfera, sin embargo, deriva de la oposición entre los hechos mentales (esto es, semióticos), que pertenecen al dominio de las ciencias soc

There are specific receptors for the active metabolite of vitamin D on the pancreatic beta cells and severe vitamin D deficiency can inhibit insulin secretion. In the present study 14 middle aged men with impaired glucose tolerance and low glucose-stimulated insulin values received 2 micrograms alphacalcidol daily for 18 months. On treatment there was a transient increase of both the peak and the

A set of measurement with moveable aperture restrictions, also called scrapers, has been carried out at MAX II (Nucl. Instr. and Meth. A 343 (1994) 644), the 1.5GeV electron storage ring at MAX-lab, Lund, Sweden. The measurements with scrapers in MAX 11 have shown to give a number of useful results, such as the vertical and horizontal acceptance, which are 7.4 x 10(-6) and 9.6 x 10-6 m, respective

The budding yeast species Saccharomyces castellii has provided important new insights into molecular evolution when incorporated in comparative genomics studies and studies of mitochondrial inheritage. Although it shows some diversity in the specific molecular details, several analyses have shown that it contains many genetic pathways similar to those of S. cerevisiae. Here we have investigated th

Low serotonin activity in man has been related to impulsive, self-destructive violence but not to instrumental aggression aimed at dominance. A relationship has also been suggested between aggression and high catecholaminergic activity. Several studies have reported signs of aberrant dopaminergic function in attention deficit hyperactivity disorder, autism, and schizophrenia. In 22 violent offende

The book contains selected articles from research in different areas produced by scientists in Scandinavia. However, many of the articles are based upon professor Göran Fagerlund's original ideas. Titles: 1.Cementitious injection grouts - penetration ability (Alemo, J. & Hansson, P.). 2.A disadvantage of high performance concrete and a simple way to avoid it (Alexanderson, J). 3. Early age t
