Cadmium accumulation in arable soils causes concern due to possible direct environmental effects and health risks associated with exposure of humans to cadmium through agricultural products. This paper discusses the problem of cadmium accumulation in Swedish arable land, and evaluates Salix (Salix vinimalis) cultivation as a tool for addressing the problem. It is found that Salix cultivation offer
This study investigated to what extent, and under what circumstances, pair collaboration influences the realism in eyewitness confidence in event memory. The participants first saw a short film clip and then confidence rated their answers to questions on its content. A condition (the Individual-Pair condition) where individual effort preceded pair collaboration showed better calibration compared w
Plants have evolved many mechanisms to increase the chance of gene dispersal mainly through pollen and environmental factors play an important role. Understanding the mechanism behind gene dispersal is therefore crucial in the correct evaluation of the use of genetically modified crops for cultivation. In this paper we address the question of weather nutrient availability for the female affects th
Crucian carp from populations that lack piscivores are extremely vulnerable to predation. However, in the presence of piscivores these fish develop an inducible morphological defence, a deep body. This switch from a vulnerable, shallow-bodied morph to a morphologically defended morph makes this species very suitable for investigations of anti-predator strategies, and trade-offs between morphologic
Energy balances are analysed from a life-cycle perspective for biogas systems based on 8 different raw materials. The analysis is based on published data and relates to Swedish conditions. The results show that the energy input into biogas systems (i.e. large-scale biogas plants) overall corresponds to 20-40% (on average approximately 30%) of the energy content in the biogas produced. The net ener
Objective. The objective was to study primary healthcare patients' understanding of their diagnosis of heart failure (HF), using patients treated for diabetes mellitus (DM) as a comparative group. Design. A cross-sectional community based study. Setting. Karlskrona community situated on the Swedish south-east coast with 60 600 inhabitants. Subjects. A total of 1402 subjects, aged 60 - 96 years in
A method for purification of recombinant apolipoprotein A1 in aqueous two-phase systems has been studied. A mutant of apolipoprotein A-I, the Milano variant, was expressed in E. coli. Phase systems containing ethylene oxide (EO)-propylene oxide (PO) random copolymers have been used. These polymers are thermoseparating and have the ability to separate into one water-rich and one polymer-rich phase
Context: When using the Case Method in teaching situations, problem-solving is emphasized and taught, in order to acquire the skills and later be able to apply them in new situations. The basis of the learning process is the students’ own activity in the situation and is built on critical appraisal and discussion. Objectives: To explain what the Case Method is, what it is not and to describe when
Understanding how environmental variation influences even cryptic traits is important to clarify the roles of selection and developmental constraints in past evolutionary divergence and to predict future adaptation under environmental change. Female yellow dung flies (Scathophaga stercoraria) typically have three sperm storage compartments (3S), but occasionally four (4S). More spermathecae are th
Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution
With the widespread transformation of information into digital form through-out society - firms and organisations are embracing this development to adopt multiple types of IT to increase internal efficiency and to achieve external visi-bility and effectiveness - we have now reached a position where there is data in abundance and the challenge is to manage and make use of it fully. This book addres
The Swedish Library Act states that “Library activities shall be available to everyone” and other policy documents in Sweden promote the public library as a place making information and culture accessible to all. The Library Acts of Denmark, Finland and Norway include similar statements, as well as the core values of the International Federation of Library Associations and Institutions. However, t
Partially premixed combustion (PPC) has shown to produce high gross indicated efficiencies while yielding lower pollutant emissions, such as oxides of nitrogen and soot, than conventional diesel combustion. Gasoline fuels with a research octane number (RON) of 60-70 have been proposed as optimal for PPC as they balance the trade-off between ensuring good combustion stability at low engine loads an
In mammals, the four native deoxyribonucleosides are phosphorylated to the corresponding monophosphates by four deoxyribonucleoside kinases, which have specialized substrate specificities. These four enzymes are likely to originate from a common progenitor kinase. Insects appear to have only one multisubstrate deoxyribonucleoside kinase (dNK, EC 2.7.1.145), which prefers pyrimidine nucleosides, bu
Cartridge cases are often the sole items left behind after a shooting incident and DNA traces from these can identify persons connected to the shooting. However, the chance of retrieving usable DNA profiles from cartridge cases is limited, due to the low amounts of deposited DNA and subsequent DNA loss associated with the firing process. In the current study, we set out to increase the DNA recover
Since the nineteenth century, the notion of heritage in Tunisia has experienced a number of different identities and political and cultural reorientations which have gradually made it primarily an instrument of tourism-related economic development. The notion of heritage in the country has evolved from one that has been historically stigmatised to a vision of much more mature preservation movement
In this work, arrays of predominantly relaxed InGaN platelets with indium contents of up to 18%, free from dislocations and offering a smooth top c-plane, are presented. The InGaN platelets are grown by metal-organic vapor phase epitaxy on a dome-like InGaN surface formed by chemical mechanical polishing of InGaN pyramids defined by 6 equivalent {101¯ 1} planes. The dome-like surface is f
Tissue transglutaminase (tTG) and microbial transglutaminase (mTG) cross-link gliadins to form complexes that expose immunogenic neo-epitopes to produce tTG and mTG-neo-epitope antibodies. The aim of this study was to test the diagnostic performance of antibodies against non-complexed and complexed forms of transglutaminases, to correlate their activities to the intestinal damage and to explore ag
Laser Shock Peening (LSP) and Shot Peening (SP) are processes used to mechanically alter the surface properties of metals by inducing a transient high-pressure wave by a laser pulse or by a high-velocity impact of a peening particle. Both processes aim to induce compressive residual stresses near the surface and the level of residual stresses obtained from SP or LSP is similar.

This paper concerns the role of teachers as street level buerarucrats in Swedish vocational healthcare education for adult students. At the center of the analysis are the challenges related to policy implementation when many of the students are second language speakers and language and communication play a role. Policy documents provide the analysis with a normative framework. Interviews with teac
