Integration of particle-gas systems with stiff mutual drag interaction

Numerical simulation of numerous mm/cm-sized particles embedded in a gaseous disk has become an important tool in the study of planet formation and in understanding the dust distribution in observed protoplanetary disks. However, the mutual drag force between the gas and the particles can become so stiff - particularly because of small particles and/or strong local solid concentration - that an ex

Perceptions of diabetes control among people with type 2 diabetes treated with basal insulin in Sweden, Switzerland, and the United Kingdom

Objective: To investigate perceptions of control among people with uncontrolled and well controlled type 2 diabetes (T2D) treated with basal insulin, as well as differences in perceptions and diabetes management practices between the two groups. Research design and methods: Web surveys of 1012 people with uncontrolled T2D (HbA1c >8.0% or 64 mmol/mol) on basal insulin in Sweden, Switzerland, and th

Lateral Protein-Protein Interactions at Hydrophobic and Charged Surfaces as a Function of pH and Salt Concentration

Surface adsorption of Thermomyces lanuginosus lipase (TLL) - a widely used industrial biocatalyst - is studied experimentally and theoretically at different pH and salt concentrations. The maximum achievable surface coverage on a hydrophobic surface occurs around the protein isoelectric point and adsorption is reduced when either increasing or decreasing pH, indicating that electrostatic protein-p

The Bystander Effect : Mesenchymal Stem Cell-Mediated Lung Repair

Mesenchymal stem or stromal cells (MSCs), a heterogeneous subset of adult stem/progenitor cells, have surfaced as potential therapeutic units with significant clinical benefit for a wide spectrum of disease conditions, including those affecting the lung. Although MSCs carry both self-renewal and multilineage differentiation abilities, current dogma holds that MSCs mainly contribute to tissue regen

Knock in spark-ignition engines : End-gas temperature measurements using rotational CARS and detailed kinetic calculations of the autoignition process

Cycle-resolved end-gas temperatures were measured using dual-broadband rotational CARS in a single-cylinder spark-ignition engine. Simultaneous cylinder pressure measurements were used as an indicator for knock and as input data to numerical calculations. The chemical processes in the end-gas have been analysed with a detailed kinetic mechanism for mixtures of iso-octane and n-heptane at different

Simultaneous two-dimensional visualization of soot and OH in flames using laser-induced fluorescence

Two-dimensional visualization of soot has been realized in flames with the use of laser-induced fluorescence in C2 from laser-vaporized soot [LIF(C2)LVS]. Soot particles are heated to vaporization temperatures by the absorption of laser radiation. C2 radicals produced by this process are excited at wavelengths around 563 nm through the transition ν′ = 0 d3∏g←ν″ = 1 a3∏u, and the subsequent fluores

Diet quality and change in blood lipids during 16 years of follow-up and their interaction with genetic risk for dyslipidemia

A high diet quality according to the Swedish nutrition recommendations is associated with a reduced risk of cardiovascular disease in the population-based Malmö Diet and Cancer cohort. To further clarify this protective association, we examined the association between high diet quality and change in triglycerides, high density lipoprotein-cholesterol (HDL-C), and low density lipoprotein-cholestero

Designing and arranging an undergraduate elective course in plastic surgery—the experiences of a Scandinavian department

Background: In recent years, the medical curricula have become more crowded and the majority of medical students are no longer exposed to plastic surgery in medical school. Previous studies have revealed that most medical students are not aware of what the speciality entails.The aims of this paper were to describe the development of an elective course, as a method for including more plastic surger

Interpretive unpacking : moderately destabilizing identities and images in organization studies

The paper reviews some basic themes in postmodernism and argues for a moderate incorporation of these themes in organization studies and methodology. This approach, named interpretive unpacking, takes issues of multiple and fluid meanings, ambiguities and fragmentation seriously without the a priori privileging of these qualities over assumptions of stable meanings and coherence in social phenomen
