Mechanisms of 200 MeV electron radiation in diamond crystal in the axial orientation

The γ-radiation by electrons with the energy of ∼200 MeV in a 100μm-thick diamond crystal has been measured at the MAX-lab experimental facility, when the electrons are incident on the crystal along the 〈100〉 axis. In this case, the intensity of the -radiation with the energy ∼1–2 MeV is approximately 16 times higher than that in amorphous matter of the same thickness. Theoretical calculations bas

Unsaturated ion diffusion in cementitious materials – The effect of slag and silica fume

This paper investigates the moisture dependency of ion diffusion in binary cementitious binders with Portland cement (OPC) in combination with slag or silica fume. Resistivity measurements and calculations with a thermodynamic model, GEMS, were used to assess the unsaturated chloride diffusion coefficient. The results show that the relation between the relative diffusion coefficient and the degree

Simulation of NOM removal by capillary NF : A numerical method for full-scale plant design

The removal of natural organic matter (NOM) from boreal lake water by a novel capillary nanofiltration (NF) membrane was predicted using a computational fluid dynamics (CFD) modelling approach. The 2-dimensional axis-symmetric model was based on a 48 m3/day NF pilot plant operating in cross-flow mode on water containing 8 mg/L total organic carbon (TOC) at fluxes ranging from 10 to 25 L/m2/h and v

Pancreatic-like enzymes of microbial origin restore growth and normalize lipid absorption in a pig model with exocrine pancreatic insufficiency

Introduction: The standard therapy for exocrine pancreatic insufficiency (EPI) is porcine-derived pancreatic enzyme replacement therapy (PERT). In the present study we tested a new approach with a mixture of pancreatic- like enzymes of microbial origin (PLEM) in a 1-week efficacy study in EPI pigs. In addition to the conventionally used coefficient of fat and nitrogen absorption (CFA and CNA), par

The effect of fatty acid binding in the acid isomerizations of albumin investigated with a continuous acidification method

The protein Human Serum Albumin (HSA) is known to undergo conformational transitions towards partially unfolded forms triggered by acidification below pH 4.5. The extent of Fatty Acids (FA) binding has been thought to have an impact on the conformational equilibrium between the native and acid forms and to be a possible explanation for the observation of more than one band in early electrophoretic

A structural study of Ruddlesden-Popper phases Sr3-xYx(Fe125Ni075)O7-δ with x ≤ 0.75 by neutron powder diffraction and EXAFS/XANES spectroscopy

The structures of Ruddlesden-Popper n = 2 member phases Sr3-xYxFe125Ni0.75O7-δ with 0 ≤ x ≤ 0.75 have been investigated using neutron powder diffraction and K-edge Fe and Ni EXAFS/XANES spectroscopy in order to gain information about the evolution of the oxygen vacancy distribution and Fe/Ni oxidation state with x. Both samples prepared at 1300°C under a flow of N2(g), with δ = 1.41-1.00, and samp

Transforming data into knowledge for improved wastewater treatment operation : A critical review of techniques

The aim of this paper is to describe the state-of-the art computer-based techniques for data analysis to improve operation of wastewater treatment plants. A comprehensive review of peer-reviewed papers shows that European researchers have led academic computer-based method development during the last two decades. The most cited techniques are artificial neural networks, principal component analysi

Colonial Africa

The immediate and long-term impacts of European colonialism on African economies and societies is a field of research that has interested historians and social scientists for a long time. European colonialism in Africa was a project that ultimately depended upon a patriarchal and racist world view. Having said that, repressive ideologies do not always cause repressive outcomes. Did colonialism cau

Prevalence of skin disease in a population-based sample of adults from five European countries

Background: There is a lack of prevalence data on skin diseases in the general adult population; most studies have been carried out in small, national or consecutive clinical samples. Objectives: To determine the prevalence of common skin disease in the general European population and to assess differences in the characteristics of treatment between countries. Methods: A random sample consisting o

Sick Leave After Surgery for Thumb Carpometacarpal Osteoarthritis : A Population-Based Study

Purpose: Patients undergoing surgery for thumb carpometacarpal (CMC1) osteoarthritis often require sick leave owing to postoperative immobilization, pain, and decreased function. Our goal was to evaluate the amount of sick leave after surgery for 2 common CMC1 arthroplasty procedures. Methods: Using registry data from the Skåne region of southern Sweden, cross-linked with employment data showing p

Crystallization of Zr0.1Ti0.9On mixed oxide by pressurized hot water and its effect on microstructural properties and photoactivity

Pressurized hot water crystallization was applied and optimized for preparation of photoactive Zr0.1Ti0.9On mixed oxide. The effect of individual processing conditions (temperature, pressure and water amount) on (micro)structure, textural, optical, electronic and photocatalytic properties in Acid orange 7 photodegradation of prepared Zr0.1Ti0.9On mixed oxide was examined. It was revealed that whil

The Regional Film Fund as Co-production Crusader - The Case of Film i Väst

A focus in this paper is the issue of possible over-production of European films, as spelled out or implied in a number of reports, chapters, books and doctoral dissertations on European cinema during the last decade. Specifically, the activities of the Swedish/Scandinavian co-producer/regional film fund/public company Film i Väst will come under scrutiny. Among a large range of activities, the fu
