The short-chain fatty acids (SCFA) formed from colonic fermentation of indigestible carbohydrates have been suggested to exert different physiological effects. In this thesis the fermentability and SCFA produced from various indigestible carbohydrates in the hind-gut were investigated using balance experiments in rats. In the case of propionate, experiments were also performed to evaluate possibl
Introduction: Transnationalism and migration Ulf Johansson Dahre The 5th annual Somalia International Rehabilitation Centre (SIRC) Conference of the Horn of Africa focused on “The Role of Diasporas in Peace, Democracy and Development”. The conference was held in Lund, Sweden, August 19-20, 2006. The content of this volume reflects some of the views and proceedings presented at the conference. I
The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blen
Arctic is contaminated with persistent organochlorine pollutants (POPs), and exposure to these compounds may differ between south and north in Norway. POPs may have negative impact on male reproductive characteristics. We compared serum levels of the CB-153 and p,p'-DDE in men who were born and had lived most of their lifetime south and north (close to or above the Arctic Circle) in Norway. We fou
Popular Abstract in Swedish För att tillverka produkter av hög kvalitet, behöver industriella företag strukturera arbetet med hjälp av instruktioner och riktlinjer som är lätta att förstå och komma åt. Dessa samlas ofta i en eller flera pärmar eller på internt datornätverk, ofta som en del av den internationella kvalitetsstandarden ISO 9000. Men detta fungerar sällan som ett välfungerande stöd förIndustrial companies supply products intended to satisfy customers’ needs and requirements. To be competitive and to maintain good economic performance, efficient systems are needed to communicate information and exchange knowledge. Such systems are often referred to as quality systems as they intend to support development as well as standardized work regarding the quality of the product and incre
We give a simpler proof of the formula, due to J.-L. Lions, for the reproducing kernel of the space of harmonic functions on a domain Omegasubset ofR(n) whose boundary values belong to the Sobolev space H-s(partial derivativeOmega), and also obtain generalizations of this formula when instead of harmonic functions one considers functions annihilated by a given elliptic partial differential operato
Physicochemical changes of dietary fibre in the presence of NaCl or CaCl2 (0, 100 or 400 mM) during boiling (4 or 25 min) of blanched/frozen carrots were investigated, Addition of NaCl (100 mM) to the boiling water reduced total dietary fibre (TDF) content, due to a reduction of insoluble polymers. Higher concentrations had no further effects. NaCl showed minor effects, on molecular weight distrib
Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report
The deactivation of a commercial Selective Catalytic Reduction (SCR) catalyst, of V2O5−WO3/TiO2 type, has been studied through comparisons with results from a full-scale biomass combustion plant to that with laboratory experiments. In the latter, the catalyst was exposed to KCl and K2SO4 by both wet impregnation with diluted salt solutions and deposition of generated submicrometer aerosol particle
The aquaporin PM28A is one of the major integral proteins in spinach leaf plasma membranes. Phosphorylation/dephosphorylation of Ser274 at the C-terminus and of Ser115 in the first cytoplasmic loop has been shown to regulate the water channel activity of PM28A when expressed in Xenopus oocytes. To understand the mechanisms of the phosphorylation-mediated gating of the channel the structure of PM28
Analytical formulas for the estimation of pressure and shear stresses due to friction on bent surfaces during the handling of fibers in the manufacture of industrial textiles and composites have been derived using the drive belt formula and Hertz contact stress relations. Experimentally measured at low speed, the forces and coefficients of friction give shear stresses in the same range as for the
Individual variation of the female sex pheromone signal in Agrotis segetum was determined by gas chromatographic analysis. The individuals varied extensively, both in absolute and relative amounts of the three major pheromone components; Z5-10:OAc, Z7-12:OAc and Z9-14:OAc. Within individuals there was a strong correspondence between the sex pheromone gland content and the signal actually emitted.
Popular Abstract in Swedish Epidemiologi är den vetenskap som studerar sjukdomars förekomst och spridning och hur detta varierar över tiden, mellan geografiska områden och mellan grupper av individer definierade i olika termer. I Malmö finns det mycket goda möjligheter att göra epidemiologiska studier av slaganfall (stroke). Dels finns ett register som följt strokeinsjuknandet sedan 1989. Dels harThe present thesis explored the epidemiology of stroke in Malmö, Sweden, an urban population of approximately 250000 inhabitants. Incidence of stroke in Malmö has been monitored since 1989. The National census investigation in 1990 was used to get information about the background population in the city. Previous studies of the seasonal and weekday variations in incidence of stroke have shown inco
The psychometric properties of a Swedish version of Haidt, McCauley and Rozin's (1994) Disgust Scale were studied. Confirmatory factor analysis of the original model with eight factors (food, animals, body products, sex, body envelope violations, death, hygiene, and magic) provided satisfactory fit to the data (N= 280), significantly better than to the alternative one-factor and five-factor models
We consider possible schemes for the resonance-enhanced two-photon ionization (RETPI) of Ne and Ar atoms under the action of bichromatic radiation of intense resonance lines of HI, HeI, and HeII in a radiation-rich astrophysical plasma. The ionization rate is comparable to or exceeds the recombination rate in rarified astrophysical plasma, which leads to the accumulation of singly ionized ions wit
