In partially premixed combustion engines high octane number fuels are injected into the cylinder during the late part of the compression cycle, giving the fuel and oxidizer enough time to mix into a desirable stratified mixture. If ignited by auto-ignition such a gas composition can react in a combustion mode dominated by ignition wave propagation. 3D-CFD modeling of such a combustion mode is chal
STUDY DESIGN: Cross-sectional. BACKGROUND: The association between muscle function and lack of knee confidence in people with anterior cruciate ligament (ACL) injury has not been well investigated. Such knowledge would help in the design of training programs for this population. OBJECTIVE: To investigate associations between self-reported knee confidence and muscle function in patients with ACL in
BACKGROUND: Intracerebral transplantation of fetal dopaminergic neurons is a promising new approach for the treatment of Parkinson's disease. Patients with parkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) have a relatively stable lesion limited to the nigrostriatal system, rendering them ideal candidates for transplantation. Improvement of motor function after neural gra
Objective To examine trends in rheumatoid arthritis (RA) as an underlying cause of death (UCD) in 31 countries across the globe during 1987-2011. Methods Data on mortality and population were collected from the World Health Organization mortality database and the United Nations. Age-standardized mortality rates (ASMR) were calculated by means of direct standardization. We applied joinpoint regress
This is the story of how a large research facility of broad European and global interest, the European Spallation Source (ESS), ended up in the small university town of Lund in Sweden. This happened in spite of the fact that a number of influential European countries were at one time or another competitors to host the facility. It is also a story about politics which attempts to illustrate how clo
Membrane hybrid processes-coagulation coupled with ultrafiltration (UF)-have become a common method to comply with the legal, chemical, and microbiological requirements for drinking water. The main advantages of integrating coagulation with membrane filtration are the enhanced removal of natural organic matter (NOM) and reduced membrane fouling. With in-line coagulation, coagulants are patched int
Objective: We aimed to study the association between neighborhood socioeconomic status at the age of 40 years and risk of ischemic stroke before the age of 50 years. Methods: All individuals in Sweden were included if their 40th birthday occurred between 1998 and 2010. National registers were used to categorize neighborhood socioeconomic status into high, middle, and low and to retrieve informatio
This is a study on the recovery and recycling of copolymer in aqueous two-phase systems containing random copolymers of ethylene oxide (EO) and propylene oxide (PO). The random copolymers separate from water solution when heated above the lower critical solution temperature (LCST). The primary phase systems were composed of EOPO copolymer and hydroxypropyl or hydroxyethyl starch. After phase separ
Although smoking is associated with cardiovascular disease (CVD), many individuals remain healthy after many years of smoking. The population based cohort 'Men born in 1914' was used to investigate whether the occurrence of non-invasively detected atherosclerosis among smokers is associated with lung function [(i.e. height-adjusted forced expiratory volume during 1 s (FEV1.0) and vital capacity (V
The influence of major surgery on HIV disease progression and decline in CD4+ cell count was evaluated in 23 seropositive haemophilia patients. 24 HIV-infected patients served as non-operated controls. In addition, 32 age-matched seronegative subjects were included. The follow-up time was up to 5 years. During the course of the study, eight of the operated (35%) and 11 of the non-operated (48%) su
Solar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for
Utvecklingen som skett i Sverige de senaste decennierna, där vi har gått från industrisamhälle till kunskapssamhälle, från hierarki till platta organisationer och från maskin till hjärna har medfört ett ökat behov av skydd för arbetsgivare. Större ansvar, närmre relation med kunder samt indirekt kontroll från ledning och styrelse har vidgat arbetstagares utrymme i arbetslivet till att bl a fatta vSweden’s business-market has change a lot during the recent decades, where the society have gone from being industrialbased to knowledgebased, where organizations has gone from hierarchy to “flat” and now we use brains instead of machines. This has led to an increasing need of protection for employers. Greater responsibility, closer customer relationships and indirect control from management has e
Unaccompanied children's migration - a study from the perspective of children The aim of the study was to examine unaccompanied children’s migration from their perspective. The questions that were formulated were those about resources and strategies that child migrants use in their everyday lives and the extent to which these resources and strategies can be considered transnational. I also exa
In the middle ages the Albanian northern tribes had their own customary law that regulated their everyday life. This customary law is called the Kanun of Lekë Dukagjini. The Kanun of Lekë Dukagjini has been passed on by the old generation orally to new generations and used by highland clans in northern Albania, Kosovo and from Albanian tribes in Macedonia and Montenegro. This oral law regulates cr
Mother tongue tuition (MTT) has been part of the Swedish educational system since 1977, with now almost 30 per cent of elementary school students eligible for the subject. With an increasingly globalized world, as well as expectations from the EU of all their member states’ citizens learning at least three languages, MTT could work as a means to meet the goal of a more linguistically knowledgeable
Microalgae belong to the group of the oldest microorganisms that can grow in both fresh and marine water. Microalgal biomass is a rich source of vitamins, lipids, pigments and essential amino acids. Microalgal biomass can be used without cracking and fractionation or it can be cracked, fractionated and purified to get particular components like vitamins, pigments, omega-3 oils and proteins. But du
Åklagarens objektivitetsplikt har under de senaste åren blivit särskilt uppmärksammad med anledning av Thomas Quick-fallet. Under 90-talet erkände Quick ett 30-tal mord, varav han blev dömd för åtta av dem. Emellertid förändrades allt år 2008 när Quick tog tillbaka sina erkännanden. Detta ledde till ett antal omprövningar, där han så småningom blev friad från samtliga åtal. I såväl domstolar som m
Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process. When shifting between gears, the speeds of the target gear and the output shaft it is supported by, have to be synch
This master thesis project was completed in partnership with Lantmännen, known for producing Gluten Free (GF) PromOat®—a concentrated oat β glucan powder. The main aim of the thesis was to explore the properties of emulsions containing GF PromOat® oat β-glucan. It specifically focuses on the critical overlap concentration, viscosity, and stability before and after high-pressure homogenization
Plasma fibrinogen concentration is important for coagulopathy assessment, and is most commonly measured using the Clauss method. Several factors, including device type and reagent, have been shown to affect results, The study objective was to evaluate performance and repeatability of the Clauss method and to assess differences between measurements performed during and after cardiopulmonary bypass
