Stable carbon isotope analysis of terrestrial plant leaves preserved in Quaternary lake sediments has the potential to provide high-resolution reconstructions of past climatic conditions. Preferably, delta(13)C measurements should be made on a single leaf component, e.g. cellulose, but this approach is often precluded by limited leaf availability. Previous work suggests that reliable palaeoclimati

Salt-containing membranes based on polymethacrylates having poly(ethylene carbonate-co-ethylene oxide) side chains, as well as their blends with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), have been studied. Self-supportive ion conductive membranes were prepared by casting films of methacrylate functional poly(ethylene carbonate-co-ethylene oxide) macromonomers containing lithium

We prove a uniqueness result for autonomous divergence-free systems of ODE's in the plane and give an application to the study of water flows with vorticity.

This essay is a critical reflection on the state of Swedish labor history.

Popular Abstract in Swedish Bibelsynsfrågor har alltid vållat heta debatter. Svenska Missionsförbundet (SMF) utgör inget undantag från den regeln. Där kom bibelsynen att diskuteras med en intensitet som fick tre bibellärare i följd att sluta vid Missionsskolan på Lidingö (där SMF:s blivande pastorer och missionärer utbildades) och lämna samfundet. På den så kallade "Valhallanatten" 1926 diskuteradThis thesis examines to what extent the issue of the views of the Bible was discussed within the Mission Covenant Church of Sweden (MCCS) during the period of 1917-1942, and if there were any conscious and decisive choices of direction concerning this issue, in spite of the fact that the MCCS has no established views of the Bible. In an introductory chapter, the views of the Bible of the great MC

Cellular redox state is an important metabolic variable, influencing many aspects of cell function like growth, apoptosis, and reductive biosynthesis. In this report, we identify NADPH as a candidate signaling molecule for exocytosis in neuroendocrine cells. In pancreatic beta-cells, glucose acutely raised the NADPH-to-NADP(+) ratio and stimulated insulin release in parallel. Furthermore, intracel

bjective: The aim of this review is to outline specific surgical complications, metabolic consequences and quality of life (QOL) following urinary diversion in patients undergoing radical cystectomy. Methods: Based on a comprehensive literature search (MEDLINE) the published knowledge on urinary diversion was examined regarding the research question with an emphasis on contemporary cystectomy se

Background: To more efficiently reduce social inequalities in mortality, it is important to establish which causes of death contribute the most to socioeconomic mortality differentials. Few studies have investigated which diseases contribute to existing socioeconomic mortality differences in specific age groups and none were in samples of the whole population, where selection bias is minimized. Th

Deletion of the transforming growth factor beta1 (TGF-beta1) gene in mice has previously suggested that it regulates both hematopoiesis and angiogenesis. To define the function of TGF-beta more precisely, we inactivated the TGF-beta type I receptor (T beta RI) gene by gene targeting. Mice lacking T beta RI die at midgestation, exhibiting severe defects in vascular development of the yolk sac and p

Current e-learning systems are increasing their importance in higher education. However, the state of the art of e-learning applications, besides the state of the practice, does not achieve the level of interactivity that current learning theories advocate. In this paper, the possibility of enhancing e-learning systems to achieve deep learning has been studied by replicating an experiment in which

The objective was to study ambulatory blood pressure and heart rate variability between day and night in patients with type 1 (insulin-dependent) diabetes mellitus with different degrees of diabetic nephropathy, and to evaluate the influence of autonomic neuropathy and type of antihypertensive treatment. Twenty type 1 diabetic patients with diabetic nephropathy and antihypertensive treatment were

We have investigated the formation of vesicles in the binary system of a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) with the average composition EO5PO68EO5 in water. Vesicles are formed when a solution of unimers is heated into a two-phase region where, at equilibrium, a concentrated lamellar phase coexists with a dilute solution of unimers. The vesicles were

Popular Abstract in Swedish Denna avhandling handlar om hur bränsleetanol kan produceras från barrved för att användas som ersättning för bensin. Den största fördelen med detta är att genom att använda etanol tillverkad av råmaterial från växtriket ökar vi inte växthuseffekten. Den koldioxid som frigörs vid förbränningen av etanolen tas åter upp av växtligheten och vi får ett slutet kretslopp. AndFuel ethanol can be produced from lignocellulosics by the enzymatic hydrolysis process, which consists of a pretreatment step prior to hydrolysis, followed by fermentation and finally refining. This thesis deals with the development of the enzymatic process using softwood as raw material. The focus has not only been on how to obtain high yields, but also on how to solve problems, which can arise i
