Porous media can be characterized by studying the kinetics of liquid rise within the pore spaces. Although porous media generally have a complex structure, they can be modeled as a single, vertical capillary or as an assembly of such capillaries. The main difficulties lie in separately estimating the effective mean radius of the capillaries and the contact angle between the liquid and the pore. In
We studied the effect of apatite amendment on ectomycorrhizal (EM) mycelial biomass production and species composition in a phosphorus-poor spruce forest using sand-filled mesh bags. Control and apatite-amended bags were buried in pairs in the lower part of the organic horizon for one growth season. DNA extraction, PCR of the ITS region, cloning and random sequencing were used to examine the funga
A two-period, career-concerns model with symmetric information but uncertainty about each worker's ability is analyzed. Contracts are unobservable, but incomes are observable. It is shown that effort is distorted upward by contracts being unobservable and that the distortion depends positively on turnover.
BACKGROUND: It is generally argued that variations in cerebral blood flow create concomitant changes in the cerebral blood volume (CBV). Because nitrous oxide (N(2)O) inhalation both increases cerebral blood flow and may increase intracranial pressure, it is reasonable to assume that N(2)O acts as a general vasodilatator in cerebral vessels both on the arterial and on the venous side. The aim of t
To reassess earlier suggested type I diabetes (T1D) associations of the insulin receptor substrate 1 (IRS1) and the paired domain 4 gene (PAX4) genes, the Type I Diabetes Genetics Consortium (T1DGC) evaluated single-nucleotide polymorphisms (SNPs) covering the two genomic regions. Sixteen SNPs were evaluated for IRS1 and 10 for PAX4. Both genes are biological candidate genes for T1D. Genotyping wa
In boreal and nemoboreal forests, tree frost hardiness is modified in reaction to cues from day length and temperature. The dehardening processes in Norway spruce, Picea abies, could be estimated to start when the daily mean temperature is above 5 degreesC for 5 days. Bud burst will occur approximately after 120-170 degree-days above 5 degreesC. dependent on genetic differences among provenances.
Data from measurements on the body burden Of (CS)-C-134, Cs-137 and K-40 in various Swedish populations between 1959 and 2001 has been compiled into a national database. The compilation is a co-operation between the Departments of Radiation Physics in Malmo and Goteborg, the National Radiation Protection Authority (SSI) and the Swedish Defense Research Agency (FOI). In a previous study the effecti
We use metal - organic vapour phase epitaxy for growth investigations of epitaxial nanowires in III - V materials, such as GaAs, GaP, InAs, and InP. In this paper we focus on gold assisted growth of nanowires. The nature of the metal particle - whether it is in the solid or liquid state - is discussed. For InAs and InP we have demonstrated that gold assisted wires can only grow at temperatures whe
This study has evaluated the sampling density for creation of high-resolution digital elevation models (DEMs) for precision agriculture purposes. The relationships between yield and topographical factors were investigated in a study area located in the central Sweden province of Dalarna. The DEM data sampling was carried out with a RTK-GPS system. A dense sampling scheme was employed and data was
Haemophilia management is not uniform among countries, even within western Europe, that have close economic, social and cultural relationship. The European Paediatric Network PedNet aims to share experiences in the field of the care of boys with haemophilia. In 1998, a PedNet survey has shown significant disparities in 20 centres from 16 countries, particularly as regards the implementation of pro
Hip fracture is associated with high early mortality. Little is known about long-term survival and subsequent fracture risk. The aim of this study was to evaluate survival and fracture risk after hip fracture in women at different ages. All women suffering a hip fracture during 1984-1985 in Malmo, Sweden, were identified (n = 766) and followd up to 22 yr or death. All new radiographic examinations
The objective was to explore the impact on physical health of a lifestyle programme among persons with psychiatric disabilities, and their caregivers. Their satisfaction with the intervention was also assessed. Somatic comorbidity and an increased mortality related to the lifestyle among persons with psychiatric disabilities are well known. Few randomized controlled trials have been aimed specific
This paper compares reasoning surrounding organic food labelling with arguments concerning mandatory GM labelling. Focus is placed on argumentative cross-overs, defined as cases where actors or organizations use a certain type of argumentation for one issue (for example, modes of food production), and shift into using their opponent's type of argumentation for a closely related issue (for example,
A sample of 125 consecutive patients from a Swedish detoxification unit were followed up at five years. Register data on criminal behavior were retrieved for 99% of all subjects, including those who were deceased at follow-up, and 76% of living subjects were interviewed. A diagnosis of antisocial personality disorder (ASPD) at intake was associated with incarceration, continuous drug use, dependen
This study was aimed at investigating the psychometric properties of the Interview Schedule for Social Interaction (ISSI), in terms of construct and discriminant validity and unidimensionality, in three psychiatric samples with varying prerequisites for social interaction: 1) an outpatient sample of working age with mixed diagnoses, 2) an outpatient sample with schizophrenia, and 3) an inpatient s
he present study focused on the functional role of the mutation Ile66Thr located in the N-terminal epidermal growth factor-like domain of coagulation factor IX (FIX). This mutation causes mild hemophilia B with approximately 25% FIX coagulant activity and FIX antigen levels of around 90% of normal. In the 3-dimensional structure of porcine FIXa and in the subsequent 3-dimensional model of human FI
BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE
