Popular Abstract in Swedish I utvecklingen av gasturbiner och förbränningsmotorer (som används i bilar, flygplan & båtar) finns idag ett modernt miljötänkande som strävar efter att reducera utsläpp och öka effektiviteten (verkningsgraden). Med användning av rätt kylmetoder kan man påverka dessa parametrar. Den bästa möjliga kyltekniken skapar utrymme för att höja temperaturen vid förbränningenThe mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. Traditional cooling schemes such as film cooling are associated with high coolant flow rates and unacceptable emission lev

Pancreatic tissue grafting is by far the most physiological therapeutic solution to the insulin deficiency of diabetes. Recent clinical trials have indicated somewhat successful use of nonsteroidal immunosuppressive regimens and a successful nonhuman primate trial using CD154 for costimulation blockade was reported. However, these protocols need to be replaced with safe and efficacious ones in whi

This thesis is concerned with laser based techniques for the measurement of fluid dynamical properties and their application to combusting flowfields or flowfields related to combustion. As an introduction, the theory of turbulent flows and combustion is shortly presented. An overview of laser based measuring techniques is given. Next, seven papers are included. The main topic of papers 1 and 2 is

A search for contributions to the reaction ep --> epi(0)N* from photon-odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-of-mass energy = 215 GeV. The measurement proceeds via detection of the pi(0) decay photons, a leading neutron from the N* decay, and the scattered electron. No pi(0) signal is observed and an upper limit on the cross sectio

Objective. To examine the help preferences of employees in the Danish police who had acknowledged that they wished to change health behaviors. In addition, we explored whether preferences varied with age, gender, chronic health concerns, positive expectations of good health, and past experiences of in-house health promotion services (i.e., wellness service). Methods. Respondents to an electronic q

Abstract in UndeterminedA heuristic model based on dielectric continuum theory for the long-range solvation free energy of a dipolar system possessing periodic boundary conditions (PBCs) is presented. The predictions of the model are compared to simulation results for Stockmayer fluids simulated using three different cell geometries. The boundary effects induced by the PBCs are shown to lead to an

Ischemic stroke triggers neurogenesis from neural stem/progenitor cells (NSPCs) in the subventricular zone (SVZ) and migration of newly formed neuroblasts towards the damaged striatum where they differentiate to mature neurons. Whether it is the injury per se or the associated inflammation that gives rise to this endogenous neurogenic response is unknown. Here we showed that inflammation without c

The response of microbial communities to long-term environmental change is poorly understood. Here, we study bacterioplankton communities in a unique system of coastal Antarctic lakes that were exposed to progressive long-term environmental change, using 454 pyrosequencing of the 16S rDNA gene (V3-V4 regions). At the time of formation, most of the studied lakes harbored marine-coastal microbial co

In this article, we suggest that the degree of (dis)unity - both between the member states (MS) in the Council and within the Commission - is a key factor in affecting the balance between Commission autonomy and MS control in international trade negotiations. We shed empirical light on this issue, and on the relative influence of MS and the Commission in general, through a case study of the Econom

Infantile colic is common, but no safe and effective conventional treatment exists. The use of acupuncture has increased despite weak evidence. This practitioner survey explores and discusses how infantile colic is regarded and treated in Traditional Chinese Medicine (TCM). The study is based on personal communication with 24 acupuncturists from nine countries. These acupuncturists specialize in p

We describe two children with significant bleeding: one with multiple ecchymoses and the other with scrotal bleeding. In both patients, the activated partial thromboplastin time (APTT) was prolonged, with positivity for lupus anticoagulants (LA). However, the Owren prothrombin time (PT), usually insensitive for LA, was also prolonged. The presence of LA is associated with diverse clinical manifest

The marsh zones of Sunderban coast were examined for modern benthic marsh foraminiferal assemblages and correlated with the typical mangrove vegetation. A total of 14 genera of foraminifera and 8 genera of mangrove plants were recorded from the region. The assemblage is characterised by agglutinated and calcareous foraminifera. The high, middle and low marshes are identified on the basis of positi

Objective. To analyse patients' self-reported reasons for not adhering to physical activity referrals (PARs). Design and setting. Data on 1358 patients who did not adhere to PARs were collected at 38 primary health care (PHC) centres in Sweden. Intervention. PHC providers issued formal physical activity prescriptions for home-based activities or referrals for facility-based activities. Subjects. O

Fennoscandia has a strong tradition in dendrochronology, and its large tracts of boreal forest make the region well suited for the development of tree-ring chronologies that extend back several thousands of years. Two of the world's longest continuous (most tree-ring chronologies are annually resolved) tree-ring width chronologies are found in northern Fennoscandia, with records from Tornetrask an

Chronic groin postherniorrhaphy pain (CGPP) is common and sometimes so severe that surgical treatment is necessary. The aim of this study was to identify risk factors for being reoperated due to CGPP.

Risk factors associated with intrauterine growth restriction (IUGR) have previously been identified, but few studies have described the relationship between IUGR and maternal stress caused by exposure to civil unrest. Here, we investigate this relationship during the Mount Elgon crisis in western Kenya between 2006 and 2008, following a period of violence. Birth weight data were compared between t
