The hydrophilic/hydrophobic properties of the membrane material have an important influence on the membrane flux reduction when treating solutions containing hydrophobic solutes. Different methods of measuring the hydrophobic properties of membranes have been evaluated; measurement of the contact angle being the most commonly used method. In this investigation the flux reduction of eight membranes
BACKGROUND Men and women with type 2 long QT syndrome (LQT2) exhibit time-dependent differences in the risk for cardiac events. We hypothesized that data regarding the location of the disease-causing mutation in the KCNH2 channel may affect gender-specific risk in LQT2. OBJECTIVE This study sought to risk-stratify LQT2 patients for life-threatening cardiac events based on clinical and genetic info
Desferrioxamine-B (DFOB) is a bacterial trihydroxamate siderophore and probably the most studied to date. However, the manner in which DFOB adsorbs at mineral surfaces and promotes dissolution is still under discussion. Here we investigated the adsorption and dissolution reactions in the goethite-DFOB system using both in situ infrared spectroscopic and quantitative analytical methods. Experiments
We are living in a highly dynamic, human-dominated Earth System in which non-linear, abrupt and irreversible changes are not only possible but also probable. These changes require institutional structures capable of steering human society away from critical tipping points and irreversible change and ensuring sustainable livelihoods for all. We see 2012 as a charter moment, a historic opportunity t
This paper decomposes the popular risk measure Value-at-Risk (VaR) into one jump- and one continuous component. The continuous component corresponds to general market risk and the jump component is proportional to the event risk as defined in the Basel II accord. We find that event risk, which is currently not incorporated into most banks’ VaR models, comprises a substantial part of total VaR. It
A method to determine the internal stress state across the grain of glued laminated wood (glulam), as well as the experimental equipment for measuring released deformation are described in this paper. The internal stress state is calculated from measured released deformations, which are measured by a contact free method based on a digital camera technique. Nondestructive measurement of the modulus
In a method and a mobile communications receiver for performing signal measurements, signal measurement data is received from at least one base station during at least part of a measurement period. Each measurement period comprises a number of non-equidistant snapshot measurement windows during which the receiver receives signal measurement data. At least one average signal strength value of the s
To facilitate high-throughput biomarker discovery and high-density protein-chip array analyses of complex biological samples, a novel macro- and nanoporous silicon surface for protein microarrays was developed. The surface offers three-dimensional surface enlarging properties and spot confinement, enabling both high sensitivity bioassays and design of high density arrays. Reproducible manufacturin
Recent advances in magnetic resonance imaging have made it possible to visualize and quantify flow of cerebrospinal fluid (CSF) in the brain. The net flow of CSF through the cerebral aqueduct was used to measure CSF production in six normal volunteers at different times during a 24-h period. CSF production varied greatly both intra- and interindividually. The average CSF production in each time in
The purpose of this paper is to provide insight into how companies work during packaging development to reduce negative environmental impact along supply chains, and to compare their practical approaches with the theoretical concepts presented in the literature. The research approach is explorative and based on nine cases in the food and manufacturing industries in Sweden. Data were collected from
The momentum and energy injection from supernovae is one of the main feedback modes, and is therefore key to the understanding of galaxy evolution and star formation. However, due to low resolution, large scale galaxy simulations often have issues with accurately modelling supernovae, and therefore rely on sub-grid models. This is especially true for the injected momentum, where capturing the mome
In this study healthy never-smoking subjects (n = 18) were recruited from a population study. Bronchoalveolar lavage (BAL), blood lymphocytes and bronchial biopsies, analysed both in the epithelium and lamina propria, were stained for T and B lymphocytes, natural killer (NK) cells and different subpopulations of T lymphocytes. In BAL, significantly higher proportions of T lymphocytes (CD3), T lymp
Rätt bakterier i tarmen kan göra det lättare att förbli smal Övervikt är ett stort problem i dagens samhälle. Övervikt och fetma kan kopplas ihop med ett antal sjukdomar som följd av övervikten. Personer med övervikt lider större risk att drabbas av hjärt– och kärlsjukdomar, diabetes typ 2 och även förtidig död. Det är visats av andra forskargrupper att överviktiga barn har en högre risk att själAbstract Problem with obesity is a growing health problem, and young children with obesity and overweight suffer a bigger risk to become overweight as adults. The aim of this study was to compare the differences which arise in the microbiota among preschool children who had participated in an intervention study. The present study includes two groups of children, whom had different body mass index
Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. The main focus of this Master’s thesis project is to develop a new and im
Motivated by the rising importance of today’s environmental issues and more specifically the role of energy conservation policies, the current study investigates the Granger causal relationship between energy consumption and economic growth in eight European countries. Using a large dataset that overall spans from 1800-2009 the study employs the Toda-Yamamoto procedure and cointegration analysis w
The issue of possession of the air has been debated over literally thousands of years. The Romans debated the ownership of the air above their cornfields. When man finally could construct aircraft, in this case a balloon, heavier-than-air in the 1780's it did not take long before the first regulation came into force. The issue of state sovereignty had been discussed since the national states s
Raman spectra of soot particles were monitored in the gaseous flow extracted from the burning regions of two low-pressure premixed ethylene flames, for the first time. The flame conditions were chosen to explore the diversity of soot nanostructure in slightly sooting flames. Evaluation of the Raman spectral parameters revealed that the soot particles exhibited a strongly disordered structure and a
Packaging innovation is a strategic and valuable tool yet underexplored in business and extended value chains. Demographic changes, as population aging, and the increase of healthcare costs pose challenges and opportunities for the pharmaceutical industry, where packaging innovation offers new opportunities to provide patients with better solutions. This study employs a multi-stakeholder perspecti
Background: Personal recovery, defined as an individual process towards meaning, is an important target within mental health services. Measuring recovery hence requires reliable and valid measures. The Process of Recovery Questionnaire (QPR) was developed for that purpose. Aims: The aim was to develop a Swedish version of the QPR (QPR-Swe) and explore its psychometric properties in terms of factor
