A spatially one-dimensional model of the hydrodynamics of a flotation column is based on one continuous phase, the fluid, and two disperse phases: the aggregates, that is, bubbles with attached hydrophobic valuable particles, and the solid particles that form the gangue. A common feed inlet for slurry mixture and gas is considered and the bubbles are assumed to be fully aggregated with hydrophobic

Objectives: The human papillomavirus (HPV) is a risk factor for a subgroup of head and neck cancers (HNC). HPV-positive and HPV-negative HNC patients encompass heterogeneous groups regarding risk factors, sociodemographic and clinical characteristics, which may influence health-related quality of life (HRQL) differently. Since this has been sparsely studied, our study investigated the association

Efficient microbial sampling from surfaces for subsequent detection and quantification is crucial in fields such as food safety and hygiene monitoring. Cotton swabs are traditionally used for sample collection, but today there are numerous swabs of alternative material and different sizes available. Recovery efficiencies of swabs for different applications have been compared in several studies. Ho

Under the influence of EU law and the ECHR, proportionality has developed into a central feature of contemporary European administrative law, on both the national and the Union level. The article examines this development with respect to the three EU Member States of Denmark, Finland and Sweden. These Nordic legal systems share certain fundamental conceptions of law, such as the limited importance

Background: Intracoronary physiology is increasingly used in nonculprit stenoses of patients with acute coronary syndromes (ACS). However, evidence regarding the safety of fractional flow reserve-based deferral in patients with ACS, compared with patients with stable angina pectoris (SAP), is scarce. Objectives: The aim of this study was to evaluate the safety of revascularization deferral on the

The substantial part of the water-soluble hemicellulose fraction, obtained when processing cellulose to produce paper and other products, has so far been discarded. The aim of this work is to reveal the interfacial properties of softwood hemicellulose (galactoglucomannan, GGM) in relation to their molecular and solution structure. In this study the sugar composition of GGM was characterised by che

BACKGROUND: Diesel exhaust is carcinogenic and exposure to diesel particles cause health effects. We investigated the toxicity of diesel exhaust particles designed to have varying physicochemical properties in order to attribute health effects to specific particle characteristics. Particles from three fuel types were compared at 13% engine intake O2 concentration: MK1 ultra low sulfur diesel (DEP1

In this article the present day relationship between church and state in Sweden is discussed. It is here argued that the year 2000 did not mean disestablishment; though formally not a state governed church, the Church of Sweden is still intimately tied to the state in several areas. Even though the Church of Sweden is formally resolved from state control, the Church of Sweden Act still provides th

OBJECTIVES: To investigate known and suggested risk factors associated with cerebral palsy in a Swedish birth cohort, stratified by gestational age. SETTING: Information on all births between 1995 and 2014 in Skåne, the southernmost region in Sweden, was extracted from the national birth register. PARTICIPANTS: The cohort comprised a total of 215 217 children. Information on confirmed cerebral pal

BACKGROUND: Increased urinary excretion of IgM and low-grade albuminuria are associated with increased risk of cardiovascular morbidity and mortality. The objective of this study was to investigate the association between urinary IgM, albuminuria, and vascular parameters reflecting arterial structure and function. METHODS: Subjects of the present study were from the Malmö Offspring study (MOS) coh
