Populärvetenskaplig sammanfattning: Naturkatastrofer är något som Sverige är relativt förskonat från. Massrörelser, alltså markrörelser i jordtäcke eller berg såsom lerskred, slamströmmar och bergras, är däremot relativt vanligt förekommande runt om i landet. Det är dessutom så att frekvensen av den här typen av fenomen förväntas öka i Sverige till följd av framtida klimatförändringar. De områdenRecent studies indicate a widespread but largely overlooked hazard of contaminant mobilisation and transport in connection to mass movement activity into surface water systems in Sweden. Concerns are exacerbated by predicted effects of climate change, which suggest national increases in rates of precipitation, pore water pressures, run -off, erosion and mass movement occurrence. In this study, the

Background and Aims: Colon capsule endoscopy (CCE) provides a non-invasive alternative to traditional colonoscopy. This study evaluated the feasibility, safety, diagnostic yield (DY), and patient satisfaction of the OMOM CC100 CCE system, with special focus on fully remote (n = 30) and partially remote (n = 89) administration across four centres to advance decentralised models. Methods: This prosp

Objective: The aim of this study was to achieve an international expert consensus on managing acute type B penetrating aortic ulcers (PAUs) and intramural haematomas (IMHs). Methods: A modified Delphi consensus process was employed to develop recommendations for the management of acute type B PAU and IMH. Surveys were sent to international experts practicing in high volume aortic centres worldwide

The power systems of drilling rigs have changed considerably since the early days of steam driven machinery. This paper reviews that progression, from mechanical and diesel electric configurations through to modern hybrid and renewable integrated systems, with a focus on the power conversion technologies that enable each stage. Coverage includes the electrical architecture of drilling rig power sy

To investigate if karyotypic features of secondary liver tumors may provide diagnostic information and if the cytogenetic patterns of primary and metastatic colorectal carcinomas (CRC) are different, 33 liver metastases were analyzed: 25 CRC, 4 small intestine carcinoids, 1 ovarian carcinoid, 1 lobular breast cancer, 1 head-and-neck squamous cell carcinoma, and 1 uveal malignant melanoma. Chromoso

This paper investigates the greenhouse gas emissions from a Swedish wetland, constructed to decrease nutrient content in sewage treatment water. To evaluate the effect of the construction in terms of greenhouse gas emissions we carried out ecosystem-atmosphere flux measurements of CO2, CH4 and N2O using a closed chamber technique. To evaluate the importance of vascular plant species composition to

The history of spinal cord injuries starts with the ancient Egyptian medical papyrus known as the Edwin Smith Surgical Papyrus. The papyrus written about 2500 B.C.by the physician and architect of the Sakkara pyramids Imhotep, describes "crushed vertebra in his neck" as well as symptoms of neurological deterioration. An ailment not to be treated was the massage to the patients at that time. This f

The recent introduction of entry inhibitors in the clinic as components of antiretroviral treatment has heightened the interest in coreceptor use of human immunodeficiency virus type 1 (HIV-1). Viruses using CCR5 as coreceptor (R5 viruses) are generally present over the entire course of infection whereas viruses using the CXCR4 coreceptor (R5X4/X4 viruses) emerge in about 50% of infected individua

Popular Abstract in English Oil resources are finite; and political and economic factors affecting oil production,together with the environmental damage associated with the increased use of oil by a rapidly growing population, have underscored the need for developing cleaner technologies based on sustainable resources. In this context, any lignocellulosic biomass that is not used in the food chainThe present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors. In one part of the

Popular Abstract in Swedish Vad har jag gjort de senaste åren? Och varför? Det är det många som har undrat. Så stundtals även jag. Vad jag skriver nedan syftar inte till att förklara detta, utan är bara ämnat som en kort introduktion. Jag har de senaste åren jobbat med gener och proteiner från både växter och bakterier. Både gener och proteiner är väldigt små saker, men även den minsta lilla sak This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. The focus has been to establish where the metal and the porphyrin binds to the enzyme, and how they are pu

Gesture-based interaction constitutes a new paradigm in human-machine interaction. The possibility to control a technical system with gestures on surfaces or in mid air makes it possible to design user interfaces that go beyond the WIMP paradigm (Windows Icons Menus and Pointers), the dominating interaction paradigm since the 1970's. After mainly having been of interest in the human-computer inter

Popular Abstract in Swedish Under de senaste decennierna har utbredningen och förekomsten i av många arter av fåglar, växter och insekter knutna till jordbrukslandskap på olika håll i Europa minskat på grund av jordbrukets rationalisering och intensifiering. För att motverka dessa negativa trender måste man ha kännedom om den relativa betydelsen av lokala och regionala ekologiska processer för popDuring the last decades, the distribution and abundance of many European species of birds, plants and insects in agricultural landscapes have declined due to agricultural intensification. To be able to mitigate these declines, it is essential to know the relative importance on local and regional ecological processes on population persistence and patterns of species richness. I have studied the ef

Popular Abstract in Swedish Cancer i tjocktarm och ändtarm (colorektal cancer) är en av de vanligaste cancerformerna i västvärlden. Årligen insjuknar drygt 5 000 människor i Sverige i denna sjukdom, och ungefär hälften av dessa dör till följd av sin cancer. De som avlider i colorektal cancer har i de allra flesta fall spridning av tumören till andra organ (metastasering). Levern är den vanligaste

Popular Abstract in Swedish PAX FÖR MANETER! Evolutionen är den process som format det liv vi ser omkring oss. Ända sedan Darwins tid har man känt till att arter och djurgrupper uppstår genom att det finns en variation mellan individer och att då tillgångarna begränsas (såsom mat eller utrymme) blir det de bäst anpassade som överlever och fortplantar sig. Flercelliga djur har funnits på jorden i kDuring the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity. Basal phyla hold a ke

Popular Abstract in Swedish I vår omgivning finns många gasformiga ämnen, vars egenskaper är sådana att de kan mätas med optiska metoder. Härvid kan man utnyttja det unika spektroskopiska fingeravtryck ämnena har. Det vill säga, att varje ämne absorberar ljus av olika färg (våglängd) på ett unikt sätt. Likaså har vissa ämnen sådana egenskaper, att då de belyses med en viss våglängd sänder de ut enMulti-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been app
