A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res
Background: Excessive and inappropriate use of antibiotics is considered to be the most important reason for development of bacterial resistance to antibiotics. As antibiotic resistance may spread across borders, high prevalence countries may serve as a source of bacterial resistance for countries with a low prevalence. Therefore, bacterial resistance is an important issue with a potential serious
In recent years, the field of remote sensing of birds and insects in the atmosphere (the aerial fauna) has advanced considerably, and modern electro-optic methods now allow the assessment of the abundance and fluxes of pests and beneficials on a landscape scale. These techniques have the potential to significantly increase our understanding of, and ability to quantify and manage, the ecological en
Popular Abstract in Swedish Kroppens immunförsvar brukar delas in i det medfödda och det adaptiva immunförsvaret. Det medfödda immunförsvaret reagerar snabbt på yttre hot såsom bakterier. Olika sorters vita blodkroppar är väldigt viktiga för detta snabba svar på infektion och i min avhandling har jag koncentrerat mig på en av dessa; neutrofilen. Neutrofilen är den vita blodkropp som först koNeutrophil elastase (NE) has important roles in innate immunity, killing pathogens and controlling the immune response; but how NE is targeted to developing granules is not understood. Therefore, the aim of this thesis was to investigate the sorting of NE. Transfection experiments in a leukemic cell line, which were confirmed in normal hematopoietic cells, showed that a population of proNE was ta
Prostacyclin is the major arachidonic acid metabolite of the vascular endothelium and is produced mainly via the cyclooxygenase-2 pathway. By acting on the prostacyclin (IP) receptor on platelets and vascular smooth muscle cells, prostacyclin exerts vasodilatory and antiaggregative/antiadhesive effects. Previous studies have shown that prostacyclin production increases after brain trauma, but the
Background. In SBRT of lung tumours no established relationship between dose-volume parameters and the incidence of lung toxicity is found. The aim of this study is to compare the LQ model and the universal survival curve (USC) to calculate biologically equivalent doses in SBRT to see if this will improve knowledge on this relationship. Material and methods. Toxicity data on radiation pneumonitis
The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. It is shown that it will be possible to discov
Popular Abstract in Swedish Bukspottkörteln (pankreas) består av en sekretorisk (exokrin) del, som producerar pankreassaft innehållande olika matspjälkningsenzymer vilka medverkar vid nedbrytningen av födan i tarmen, samt en hormoninsöndrande (endokrin) del, som producerar insulin och andra hormon vilka reglerar näringsomsättningen i kroppen. Vid en underproduktion av enzymer, exokrin pankreatisk Exocrine pancreatic insufficiency (EPI), resulting from disease (e.g. cystic fibrosis, chronic pancreatitis) or surgery (e.g. pancreectomy or pancreas duct ligation), leads to disorders in the digestive system, such as, maldigestion, malabsorption and finally malnutrition. Pancreatic duct-ligated (PDL) pigs have been used as a suitable large-animal model to study the conditions and treatment of EP
Popular Abstract in Swedish Tjugo patienter som deltog i psykiatrisk öppenvård baserad på arbetsterapi undersöktes beträffande behandlingsresultat, uppfattningen om vårdklimatet och upplevelsen av behandlingsrelationen med arbetsterapeuten. Psykiatriska symtom, global mental hälsa, livskvalitet och fungerandet i dagligt liv studerades vid inskrivning i behandlingen, vid utskrivning, samt vid en etThe outcomes of 20 patients participating in occupational group therapy at a psychiatric outpatient unit were explored and related to perceptions of the ward atmosphere and the treatment process. The outcome variables - psychiatric symptoms, global mental health, quality of life, and occupational functioning - were measured at admission, at discharge, and 1 year after discharge. The ward atmospher
We report on charged hadron production in deuteron-gold reactions at roots(NN) = 200 GeV. Our measurements in the deuteron direction cover 1.4
Abstract in UndeterminedA new phantom has been designed that can provide simultaneously different target to background activity ratios with a linearly changing diameter of lesions. The purpose of the study was to describe and perform initial measurements with the phantom aimed to characterize different nuclear medicine tomographic systems and reconstruction algorithms in their performance and beha
We present results of a search for two hypothetical strange dibaryon states, i.e. the H-dibaryon and the possible (Lambda n) over bar bound state. The search is performed with the ALICE detector in central (0-10%) Pb-Pb collisions at root S-NN = 2.76 TeV, by invariant mass analysis in the decay modes (Lambda n) over bar (d) over bar pi(+) and H-dibaryon -> Lambda p pi(-). No evidence for these bou
The impact of pH coupled to process design for the conversion of the energy crop Arundo donax to ethanol was assessed in the present study under industrially relevant solids loadings. Two main process strategies were investigated, i.e. the traditional simultaneous saccharification and co-fermentation (SSCF) and a HYBRID design, where a long high temperature enzymatic hydrolysis step was carried ou
Background: Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has two major functions: the stimulation of the growth hormone production and the stimulation of food intake. Accumulating evidence also indicates a role of ghrelin in cancer development. Methods: We conducted a case-control study to examine the association of common genetic variants in the genes coding
