Popular Abstract in Swedish Olika laserbaserade mätmetoder för diagnostik av förbränningsmotorrelaterade fenomen har utvecklats och demonstrerats, såväl utanför som i motorer. Följande områden har studerats: -Inverkan av inhomogen bränsle-/luftblandning på cykel-till-cykelvariationer hos förbränningen i en otto-motor studerad genom laserinducerad fluorescens (LIF) på bränslet. -Restgasers inverkanVarious laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. Four different approaches were applied with the aim of investigating the applicability of these approaches in a running engine. I

OBJECTIVES: To explore the development of hypertension (HT) in a cohort of young middle-aged men. DESIGN: Prospective birth-cohort study of men surveyed over 6 years. SETTING: Helsingborg County Hospital, Sweden, 1990-97. SUBJECTS: A total of 628 men born in 1953-54, all surveyed at 37, 40 and 43 years of age. MAIN OUTCOME MEASURES: Systolic blood pressure (SBP), diastolic blood pressure (DBP), S-

OBJECTIVE: To compare the outcome of patients operated on acutely for ruptured abdominal aortic aneurysms (AAA) or otherwise symptomatic aortic aneurysms in a university hospital and in two county hospitals by the same group of vascular surgeons. DESIGN: Retrospective study. SETTING: 1 university and 2 county hospitals, Sweden. SUBJECTS: 108 patients operated on urgently for AAA, 81 at the univers

Objectives. To study changes in: (i) the prevalence of hormone-replacement therapy (HRT) and (ii) women's attitudes and knowledge about the climacteric. Design. Cross-sectional comparison was performed on two populations of women both aged 46-62 years and resident in the same urban Swedish population over a period of 6 years. Materials and Methods. In 1992, a random sample of 5990 women, from five

Background: Rat models of peritoneal dialysis (PD) are useful for studying the physiology of peritoneal transport and evaluating new osmotic agents. Intraperitoneal (IP) solute concentrations and their evolution over time are easy to measure, but IP volume (IPV) is not. Direct volumetric measurements are the "gold standard;' but they are expensive and do not allow for repetitive measurements in th

The emissions of particles, and gaseous compounds, into the ambient air from biomass-fired moving grate boilers were characterized under different boiler operation conditions. The boilers had a thermal capacity of similar to1 MW. The flue gas cleaning systems consisted of multicyclones for the removal of coarse particles. Dry wood fuel that consisted of shavings, wood chips, and sawdust from a loc

An alpha-L-arabinofuranosidase gene was identified in a sequenced genome of a novel thermophilic bacterium, which belongs to the recently described phylum of Thermomicrobia. Amino acid sequence comparison of the enzyme (designated AraF) revealed similarity to glycoside hydrolases of family 51. The gene was cloned into Escherichia coli and its recombinant product expressed and purified. The enzyme

Only single cases with rheumatoid arthritis of the thoracic spine with vertebral subluxation have been reported to date. In a review of 100 patients with severe rheumatoid arthritis who had undergone occipitocervical fusion, arthritis of the upper thoracic spine with subluxation was discovered on conventional radiographs in four patients. Two additional patients were found elsewhere. Magnetic reso

Huntington's disease (HD) is a fatal genetic neurodegenerative disorder caused by a CAG triplet repeat expansion in the gene encoding the protein huntingtin. The most studied model of HD, the R6/2 transgenic mouse, replicates many features of the disease. In addition to motor, cognitive, and endocrine dysfunctions, these mice exhibit a progressive disruption of circadian rhythms. This is accompani

The data on biologic effects of nonthermal microwaves (MWs) from mobile telephones are diverse, and these effects are presently ignored by safety standards of the International Commission for Non-Ionizing Radiation Protection (ICNIRP). In the present study, we investigated effects of MWs of Global System for Mobile Communication (GSM) at different carrier frequencies on human lymphocytes from heal

The stopping powers in silicon of heavy ions, with atomic numbers ranging from 4 to 29, have been determined using a time-of-flight elastic recoil detection analysis (TOF ERDA) set-up. In transmission geometry, the energy loss of heavy elastic recoils in the self-supporting silicon foil of known thickness is measured over a continuous range of recoil energies using time-of-flight (TOF) spectrometr

Popular Abstract in Swedish Denna avhandling i socialantropologi ägnas åt analysen av sociala och kulturella processer i Visaginassamhället efter sovjettiden. Visaginas (tidigare Sniechkus) byggdes under sovjettiden, åren 1975-1989, som hemvist för personal vid Ignalinas kärnkraftverk och deras familjer. De flesta invånarna i staden är ryssar som kom till Litauen mellan 1975 och 1989 för att byggaThis thesis focused on an examination of human agency and strategies for responding to rapid social and economic change. Fieldwork was carried out in the community of Visaginas town that was built during the Soviet period in Lithuania. The town is situated next to the Ignalina nuclear power plant. The majority of the town's inhabitants are Russians who immigrated to Lithuania from other areas of t

Antimicrobial peptides are generated during activation of the complement system [Nordahl et al. Proc. Nat1. Acad. Sci. U. S. A. 2004, 101:16879-16884]. Here we show that the anaphylatoxin C3a exerts antimicrobial effects against the yeast Candida. Fluorescence microscopy and electron microscopy analysis demonstrated that C3a-derived peptides bound to the cell surface of Candida, and induced membra

Popular Abstract in Swedish Avhandlingen "Decolonizing the Viking Age", i två volymer, argumenterar för att den skandinaviska vikingatiden kan ses som en teoretisk konstruktion som i allt väsentligt utarbetades under det sena 1800-talet. Detta tankesystem har därefter i allt väsentligt reproducerats till våra dagar. Konstruktionen av vikingatiden påverkades kraftigt av nationalism och evolutionsteDecolonizing the Viking Age 1 argues that the Scandinavian “Viking Age” can be seen as a system of knowledge constructed in the late 19th century and in its basic structures maintained up to the present day. This system of knowledge was heavily influenced by the nationalistic and evolutionary ideas of its time of making and may be described as a colonialism of the past. The book follows the making
