We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0
The challenges for creating a greener economy and the institutional framework for sustainable development pass necessarily, or mostly, through cities, as they concentrate a large and growing part of the world’s economy and population, as well as decision-making power. With the processes of urbanization and rural-urban transformation, the economy in cities, especially in cities of developing countr
Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was
Popular Abstract in English All ordinary matter around us is made out of atoms. In turn, the building blocks of the atoms are nowadays known to be three types of particles:electrons, protons and neutrons. The latter are called nucleons, as they together form the positively charged nucleus of the atom, around which the electrons are moving. The radius of the nucleus is about three orders of magnituComprehensive experimental knowledge of the 62Zn nucleus has been obtained from the combined statistics of four different experiments. The Gammasphere Ge-detector array in conjunction with the 4pi charged-particle detector array Microball was used to detect the gamma-rays in coincidence with evaporated light charged particles. In total twenty seven band structures have been observed in 62Zn, twent
This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying
Language cultivation and grammars in Sweden and Denmark 1550-1800.
The aim of this study was to investigate determinants of help from informal or formal caregivers or a combination of both among people aged 75 or more and living at home, and the characteristics of the recipients, the help they received and their quality of life (QoL). The sample for this study was 448 elderly people, 75-99 years of age, living at home and receiving help with activities for daily
PURPOSE. To characterize the spectrum of mutations in the OPA1 gene in a large international panel of patients with autosomal dominant optic atrophy (adOA), to improve understanding of the range of functional deficits attributable to sequence variants in this gene, and to assess any genotype-phenotype correlations. METHODS. All 28 coding exons of OPA1, intron-exon splice sites, 273 bp 5' to exon 1
With the attempts to achieve higher thermal efficiency, turbine blades are exposed to very high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is important to obtain a good understanding of both the complex flow field and the heat transfer characteristics in turbine rotor/stator hot-gas passa
In the Nordic Reference Interval Project 2000 (NORIP) serum, Li-heparin plasma and EDTA buffy coat were collected at 102 laboratories in 5 Nordic countries from healthy individuals aged 18 years or more and evenly distributed for laboratory, gender and age. Multiple aliquots of these samples from each of about 3000 persons are now stored at the Nordic Reference Interval Project Bio-bank and Databa
This study characterizes the high-fat diet-fed mouse as a model for impaired glucose tolerance (IGT) and type 2 diabetes. Female C57BL/6J mice were fed a high-fat diet (58% energy by fat) or a normal diet (11% fat). Body weight was higher in mice fed the high-fat diet already after the first week, due to higher dietary intake in combination with lower metabolic efficiency. Circulating glucose incr
Vanadia was deposited on TiO2, ZrO2, HfO2, Nb2O5, and Ta2O5 supports using impregnation with either an oxalic acid solution of NH4VO3 or a solution of vanadyl acetylacetonate in ethanol. Prepared samples, with a nominal vanadia content in the range 0.5–2 monolayers, were characterized with X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman and infrared spectroscopy, and were us
When skin specimens are exposed in vitro to L-dopa and catecholamines these substances accumulate in the Langerhans cells where they can be visualized with the histofluorescence method of Falck and Hillarp. Some methodological aspects are discussed and a preliminary study of Langerhans cells in contact allergy is reported.
A general model for pressure drop calculations in siphons and riser tubes has been developed. The model takes into account different physical flow phenomena such as inlet pressure drop and pressure drop in the tube. For each phenomenon, we applied theory and established correlations to calculate the separate accelerational, frictional, gravitational, and centrifugal pressure drops. Model results a
This chapter describes the utilization of recent extraction techniques such as supercritical fluid extraction, pressurized liquid extraction and microwave-assisted extraction for the determination of persistent organic pollutants in food and feed samples. These techniques have been developed because the extraction step can severely limit the entire analytical procedure. Several food crises, for ex
