This study describes the removal of polycyclic aromatic hydrocarbons (PAHs) from creosote oil contaminated soil by modified Fenton's reaction in laboratory-scale column experiments and subsequent aerobic biodegradation of PAHs by indigenous bacteria during incubation of the soil. The effect of hydrogen peroxide addition for 4 and 10 days and saturation of soil with H2O2 on was studied. In both exp
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
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
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
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
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
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
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.
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, 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.
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
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
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
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
