The mallard Anas platyrhynchos is a reservoir species for influenza A virus in the northern hemisphere, with particularly high prevalence rates prior to as well as during its prolonged autumn migration. It has been proposed that the virus is brought from the breeding grounds and transmitted to conspecifics during subsequent staging during migration, and so a better understanding of the natal origi
For decades, enhancement of ice concentrations above those of active ice nucleus aerosols was observed in deep clouds with tops too warm for homogeneous freezing, indicating fragmentation of ice (multiplication). Several possible mechanisms of fragmentation have been suggested from laboratory studies, and one of these involves fragmentation in ice-ice collisions. In this two-part paper, the role o
The structural properties, and the intracrystalline swelling of Na+-, and Ca2+-montmorillonite (Na-, and Ca-mmt) have been investigated as an effect of decreasing the relative permittivity of the solvent, i.e. from water to ethanol (EtOH), utilizing the experimental techniques; small angle X-ray scattering (SAXS) and osmotic pressure measurements. The experimental data were compared with the conti
A surface complexation model describing the adsorption of three benzenecarboxylates (phthalate, trimellitate, and pyromellitate) on goethite (alpha-FeOOH) was calibrated on data using goethite particles of 37 and 43 m(2)/g surface area. The models predict potentiometric titration and batch adsorption data with the multisite complexation model coupled with the three-plane model to account for surfa
Background: Psychosocial resources as well as lifestyle habits during pregnancy have been shown to effect the risk of having a small-for-gestational-age (SGA) child. Most previous studies are based on a single assessment of these exposures, which does not take into account the possibility of different effects during early add late stages of pregnancy. Methods: The impact of psychosocial and lifest
Particle size distribution (size-range 3-900 nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in September-November 2002. The study investigates the contribution from urban versus regional sources of particle number and mass concentration. The total particle number (ToN) and NOx are well correlated at
A new key palaeomagnetic pole (Plat. = 64.3 degrees S, Plon. = 271.0 degrees E, N = 14, A(95) = 9.2 degrees; Q = 5) is calculated from a primary magnetization isolated in early Neoproterozoic Aguapei basic sills and dykes hosted by 1.3-1.0 Ga sedimentary rocks from the southwestern part of the Amazon craton. The characteristic remanence carried by stable, pseudo-single domain titanomagnetite shows
The influence of total hepatectomy on cerebral energy state, ammonia-related amino acids of the brain tissue and plasma amino acids was studied in anaesthetized rats after total hepatectomy. The hepatectomy was performed with the aid of a microsurgical three-stage procedure. In the first stage, division of the inferior vena cava was performed. In the second stage 4 weeks later a porta-caval anasto
Bile-tolerant Helicobacter spp. are emerging human and animal pathogens. However, due to their fastidious nature, which requires nutrient-rich complex media to grow, infection with these bacteria may be underestimated. The accumulation of toxic metabolites in cultures may be one of the main obstacles for successful culture of these organisms. The present study examined various potential growth-enh
The anaphylatoxic peptide C3a is a pro-inflammatory mediator generated during complement activation, whose specific G protein coupled receptor is expressed on granulocytes, monocytes, mast cells, activated lymphocytes, and in the nervous tissue. We have generated RBL-2H3 cell clones stably expressing mutants of the human C3a-receptor (C3aR) with combined alanine (Ala) substitutions of ten C-termin
The level crossing method was used to measure the hyperfine structure of Bi 209 in the 6 p 2 ( 3 P 0 )6 d 2 D 3/2 and 6 p 2 ( 3 P 1 )7 s 4 P 3/2 levels of the Bi I spectrum. For the magnetic dipole and the electric quadrupole interaction constants a and b the following values were obtained: | a (6 p 2 ( 3 P 0 ) 6 d 2 D 3/2 )| = 128.0(0.6) g J /-0.79 MHz | b (6 p 2 ( 3 P 0 ) 6 d 2 D 3/2 )| = 58(4)
Extended producer responsibility (EPR) is a concept from Industrial Ecology that has changed waste management policies inside and gradually outside the member countries of the Organisation for Economic Co-operation and Development (OECD). This article bridges the gap in our understanding of the policy process wherein policy change occurred. It employs the Advocacy Coalition Framework (ACF) to expl
This paper studies the problem of determining the absolute pose of a perspective camera observing a scene through a known refractive plane, the flat boundary between transparent media with different refractive indices. Efficient minimal solvers are developed for the 2D, known orientation and known rotation axis cases, and near-minimal solvers for the general calibrated and unknown focal length cas
Context: Large epidemiological studies often collect non-fasting samples, although the reliability of biomarkers may be uncertain. Objective: To explore the reliability and reproducibility of a single measurement of selected biomarkers in a sub-sample of the Malmö Diet and Cancer cohort. Methods: We estimated single- and average-measures intraclass correlation coefficients (ICC) for oxidized (ox)-
Denna studie ämnar undersöka samspelet mellan den mediala gestaltningen av en stad samt de strategier som används i försök att påverka densamma. Studien avser därmed öka kunskapen om skapandet och förmedlandet av platsvarumärken samt den strategiska kommunikationens betydelse för denna process. Med en hermene-utisk ansats har kvalitativa intervjuer samt kvantitativ såväl som kvalitativ inne-hållsa
In recent times, Japan has witnessed a diversified labor market with the increase of nonregular workers. Today, more than one third of all workers in Japan are non-regular workers. The dominant form of unionism in Japan is the enterprise unions who, traditionally, have only organized regular workers. The purpose of this case study was to see whether the organizing strategies among the enterprise
The aim with this thesis is to clarify the scope of the Schumacker doctrine and specifically to answer the questions "Which tax rules are considered to take into account the ability to pay?" and "What are the thresholds for determining when a non-resident is in a comparable situation to that of a resident?". The findings of the study are that such rules are difficult to ident
