Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi

This paper presents the concept and initial work on a microfluidic platform for bead-based analysis of biological sample. The core technology in this project is ultrasonic manipulation and trapping of particle in array configurations by means of acoustic forces. The platform is ultimately aimed for parallel multistep bioassays performed on biochemically activated microbeads (or particles) using su

A common industrial process for separating particles from a liquid is continuous sedimentation, which is used in the chemical, mining, pulp-and-paper and food industries. It can also be found in most wastewater treatment plants, where it is a crucial subprocess of a complex biological system. The process has provided, and will continue to provide, scientific problems that lead to fundamental resea

The effect of hydrogen enrichment to natural gas flames was experimentally investigated at atmospheric pressure conditions using flame chemiluminescence imaging, planar laser-induced fluorescence of hydroxyl radicals (OH PLIF), and dynamic pressure monitoring. The experiments were performed using a third generation dry low emission (DLE) burner used in both SGT-700 and SGT-800 industrial gas turbi

The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labo

[Context & motivation] For market-driven software product developing organizations operating on a competitive open market, it is important to plan the product’s releases so that they can reach the market as early as possible with a competitive level of quality compared to its competitors' products. Hence, quality requirements can be seen as a key competitive advantage. The QUPER model was deve

Background: This study investigates responses to requests for clarification in conversations between children/adolescents with cochlear implant (CI) and normally hearing peers. Earlier studies have interpreted a more frequent use of requests of confirmation (yes/no interrogatives) in the CI group as a conversational strategy used to prevent communication breakdowns and control the development of t

The Kruppel-like protein ZNF224 is a co-factor of the Wilms' tumor 1 protein, WT1. We have previously shown that ZNF224 exerts a specific proapoptotic role in chronic myelogenous leukemia (CML) K562 cells and contributes to cytosine arabinoside-induced apoptosis, by modulating WT1-dependent transcription of apoptotic genes. Here we demonstrate that ZNF224 gene expression is down-regulated both in

Objective. Lack of adherence with pharmacological therapy is a public health concern that compels tremendous costs for the health care system and the community. To analyse the association between socioeconomic disadvantage and primary nonadherence with medication, and to explore possible mediating effects of trust in health care and lifestyle profile. Design. Cross-sectional population-based study

Anomi är ett centralt rättssociologiskt begrepp introducerat av Émile Durkheim (1858-1917) som beskriver ett tillstånd av oklarhet och normlöshet som överförs på individen vilket får denne att känna otillfredsställelse. Identifieringen av anomi indikerar rättsliga förändringsprocesser och tydliggör samtidens rättskultur när mönster bryts. Kränkningsersättning, s.k. rent ideellt skadestånd, som akt

In this paper we present a novel method for predictive coding with application to transmission of speech over packet-switched networks. Our method uses multiplexing to distribute a part of the information about a segment of each speech signal in several data packets while keeping the data packet rate and payload for that part of the information unchanged. We investigate three multiplexing schemes:

Objectives. To assess waiting times for three groups of orthopaedic patients in Sweden and to identify factors explaining variations in waiting time. Also examined were factors associated with patients' perceptions that waiting times were too long. Design. Retrospective study. Setting and study participants. Patients from orthopaedic units at 10 Swedish hospitals participated in the study. A quest

In 2000 the European Council agreed on the so called ‘Lisbon Strategy’, the purpose of which is to make the European Union the strongest and most competitive economy in the world and also to fight unemployment and secure social welfare systems. One year later, in 2001, an ‘environmental dimension’ was supplemented to the Lisbon Strategy at the Council meeting in Gothenburg. An ‘EU Strategy for Sus

Abstract Aims: The aim of this thesis was to investigate how the impact of Parkinson’s disease, a chronic neurodegenerative disorder, influences the person’s health-related quality of life. The aim was also to investigate nursing assessment and management of Parkinson’s in elderly persons. Methods: The study started in1998, one year later a follow-up was conducted. The sample contained in the fir

Popular Abstract in Swedish De befintliga terapier som finns att tillgå mot hjärntumörer, t. ex strålning, kemoterapi och kirurgi, har varit utan framgång och få patienter lever längre än två år efter diagnostisering. Vi har försökt att etablera en ny terapi mot hjärntumör, som använder kroppens eget immunsystem för att lokalisera och avdöda tumörceller. Kroppens immunsystem innehåller olika celltImmunotherapy is a new promising approach in cancer treatment. In the future, it will hopefully offer an alternative to existing brain tumors treatments, which are unable to cure. We have established an experimental, low immunogenic, brain tumor model in the rat. We have increased tumor cell immunogenicity with mutagen treatment or transfection of IFN-g. Mutagen treated glioma cells (tum-) could c

Recently, new cycles for power generation, such as wet cycles and cycles for CO₂ capture, have gained increasing interest. These new cycles use some sort of dilution in the air/fuel mixture, e.g. steam or CO₂. Gas turbine cycles using LCV gases can also be said to fit this description. Almost all modern gas turbines use a lean premixed combustion system, since it combines low

Despite the ongoing globalisation of economic activities, innovation does not take place randomly distributed over space, but concentrates in certain locations. A central argument to explain the spatial concentration of innovation activities lies in the ability of geographical proximity to facilitate interactive learning and knowledge exchange, which in turn is seen as an important driver for regi

To assess the distribution of blood from the umbilical vein (UMV), inferior vena cava (IVC) and superior vena cava (SVC) to either side of the fetal lamb heart by using ultrasound enhanced contrast agent imaging. By injection of ultrasound contrast agents (UCA) in UMV, IVC or SVC, the blood from these vessels was tracked, as it then was highly echogenic. By evaluating the image intensity within th

Abstract in UndeterminedNorm supporting actors and structures for change.Education every day effects almost half of the population in Sweden and Nordic countries. Most research on schools and education is based within education science and there is a lack of other social science perspectives. Sociology of law with its focus on social norms, ethical values and legal norms has something different to
