Growth and exopolysaccharide formation by Pediococcus damnosus 2.6 in beta-glucan suspensions of oat and barley
The formation of exopolysaccharides (EPS) by Pediococcus damnosus strain 2.6 was investigated in two different high P-glucan suspensions of oat (OBC) and barley (BBC). Bacterial growth was confirmed by measuring pH, colony forming units (cfu), viscosity and ropiness during growth. Growth and an increase in viscosity of the beta-glucan suspension based on oat were observed whereas only a minor grow

Concentration polarization and fouling during ultrafiltration of colloidal suspensions and hydrophobic solutes
Flux reductions experienced during ultrafiltration are due either to concentration polarization or fouling. It is usually difficult to distinguish between these two phenomena, but by using a turbulence-promoting module it is possible to determine the reversibility of a flux reduction, and thus distinguish between concentration polarization and fouling. By using a turbulence-promoting module, it is

Influence of urban geometry on outdoor thermal comfort in a hot dry climate: A study in Fez, Morocco
There are few studies on the microclimate and human comfort of urban areas in hot dry climates. This study investigates the influence of urban geometry on outdoor thermal comfort by comparing an extremely deep and a shallow street canyon in Fez, Morocco. Continuous measurements during the hot summer and cool winter seasons show that, by day, the deep canyon was considerably cooler than the shallow
Sexåriga barns syn på övergångsobjekt – En intervjuundersökning
Rheumatoid factor and antibodies to cyclic citrullinated peptides are associated with severe extra-articular manifestations in rheumatoid arthritis.
Objective: To study antibodies to cyclic citrullinated peptides (anti-CCP) and rheumatoid factor in patients with active, severe extra-articular rheumatoid arthritis (ExRA) compared with controls without ExRA. Methods: 35 consecutive patients with severe ExRA manifestations according to predefined criteria were studied. 70 patients with rheumatoid arthritis, but no ExRA manifestations, individuall
The lichen flora of Stora Karlsö and Lilla Karlsö
In 1993-1998 the lichen flora of Stora Karlso and Lilla Karlso was surveyed. These two nearby islands are situated outside the west coast of Gotland, Sweden, in the Baltic Sea. In all, 355 species were found, including three lichenicolous fungi. Two species are new to Sweden, viz. Lepraria flavescens and Placynthium lismorense. Both were found on limestone. The number of species according to habit
MIMO Decoding Algorithm and Implementation
Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. The main contributions consist of four algorithms and three VLSI i
Immunodeficiency mutation databases - A new research tool
Recently, international study groups have collected mutations for X-linked immunodeficiency diseases. In this issue of Immunology Today five databases are reported, comprising mutations from over 1000 patients, facilitating detailed analysis of genetic, immunological, biochemical and structural parameters.
Semiconductor nanowires for 0D and 1D physics and applications
During the last 5 years the potential for applications of semiconductor nanowires has grown rapidly via the development of methods for catalytically induced nanowire growth using the, so-called vapor-liquid-solid (VLS) growth mode. The VLS method offers a high degree of control of parameters such as position, diameter, length and composition, including the realization of atomically abrupt heterost
Squamarina scopulorum new to Sweden.
Squamarina scopulorum, until now only known from Norway, is reported from one locality in Padjelanta National Park in northern Sweden. It was found growing on a S-facing rock surface in the low alpine zone on the mountain Unna Djidder near Staloluokta.
From critters to cancers: bridging comparative and clinical research on oxygen sensing, HIF signaling, and adaptations towards hypoxia
The objective of this symposium at the First International Congress of Respiratory Biology (ICRB) was to enhance communication between comparative biologists and cancer researchers working on O-2 sensing via the HIF pathway. Representatives from both camps came together on August 13-16, 2006, in Bonn, Germany, to discuss molecular adaptations that occur after cells have been challenged by a reduce
Three - dimensional ultrasound studies of the cervix in pregnancy
Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ
Gamma-ray Spectroscopy of the Doubly Magic Nucleus 56Ni
The doubly magic N = Z nucleus Ni-56 has been investigated with two fusion-evaporation reactions; Ca-40(Si-28, 3 alpha)Ni-56 at a beam energy of 122MeV and Si-28(S-32, 2p2n)Ni-56 at 130MeV. To detect gamma-rays in coincidence with evaporated particles the Ge-detector array Gammasphere was used in conjunction with the charged-particle detector system, Microball and a 1 pi neutron detector array. Re
A detrimental effect of emotion on picture recollection
Several studies indicate that the recollection process, as assessed by the Remember-Know paradigm (Tulving, 1985) is enhanced for emotional stimuli as compared with neutral ones. The goal of this study was to assess the influence of emotion on recollection process, applying the Processes Dissociation Procedure (PDP; Jacoby, 1991) on emotional and neutral pictures. A total of 63 participants (aged
Continental-scale patterns of nutrient and fish effects on shallow lakes: synthesis of a pan-European mesocosm experiment
1. Results are analysed from 11 experiments in which effects of fish addition and nutrient loading on shallow lakes were studied in mesocosms. The experiments, five in 1998, six in 1999, were carried out in six lakes, distributed from Finland to southern Spain, according to a standard protocol. 2. Effects of the treatments on 29 standard chemical, phytoplankton and zooplankton variables are examin
