The Hans Tausen drill site was requested to be on a local dome, as high as possible, with a simple flow pattern and with an undisturbed flow pattern even close to bedrock. The first mapping of the surface elevation was performed as part of a general mapping of the elevation and gravity over Greenland. Later, NASA performed a few overflights of the ice cap. Combining the passes, it was possible to
Popular Abstract in Swedish Egenskapsorienterade system (eng: property-oriented) är en ny slags informationssystem som är baserade på begrepp för egenskaper istället för begrepp för ting eller klasser av ting. Genom att fokusera på egenskaper, kan de egenskapsorinterade systemen göras mer flexibla och mer lämpade för de tidiga skedena av design än de traditionella klassorienterade systemen kan varProperty-oriented systems are a new kind of information systems that are based on concepts of properties instead of concepts of things or classes of things. By focusing on properties, the property-oriented systems become more flexible and more suited to the dynamic early stages of design than the traditional class-oriented systems can be. The theoretical framework for property-oriented systems de
Popular Abstract in Swedish Proteinstrukturmodellering-att gissa struktur och funktion (artikel I och manuskript I) Proteiner har många funktioner i cellens komplicerade maskineri. Ett protein består kemiskt av en rad sammmanlänkade byggstenar, aminosyror, varav det finns 20 olika mest förekommande. En proteinkedja viker ihop sig enligt ett speciellt mönster för att och bilda ett funktionellt proKnowledge of biomolecules three-dimensional structure has provided a detailed understanding of their function. In recent years the number of new protein sequences has far exceeded the number of protein experimental structure determinations. One goal of the new field of protein structural bioinformatics is to provide reliable and automated protein functional annotations and initial protein structur
Popular Abstract in Swedish Avhandlingen behandlar ett område beläget cirka 65 km nordväst om Rom, och är en detalj- studie av områdets arkeologi, i syfte att belysa förhållandet mellan en tätbebyggelse, Luni sul Mignone och dess kringland. Grundtemat är förändringar i demografi och bebyggelse över tiden, som dessa kan ses i olika slags materiella lämningar. Även andra aspekter än de rent demografThis thesis is an archaeological study of a small region in northern Latium and the diachronical relationship between a nucleated settlement and its rural landscape. The work has a twofold basis: a review of earlier research concerning the settlement Luni sul Mignone in the light of more recent research, and a survey conducted by the present author of the territory of Luni. This survey and its res
The lean stability limit of a prototype syngas burner is investigated. The burner is a three sector system, consisting of a separate igniter, stabilizer and Main burner. The ignition sector, Rich-Pilot-Lean (RPL), can be operated with both rich or lean equivalence values, and serves to ignite the Pilot sector which stabilizes the Main combustion sector. The RPL and Main sectors are fully premixed,
Popular Abstract in Swedish I beredskapen för kärnolyckor är mobila in situ gammaspektrometriska mätningar ett viktigt redskap; vilket betyder att mätinstrument placeras i ett fordon (tex bil, flygplan eller helikopter) och gammastrålningen från omgivningen mäts under körning. I detta arbete har strategier och analysmetoder för två olika användningsområden utvecklats: 1) sökning av försvunna radioMobile in situ gamma spectrometry is an important instrument in the emergency preparedness for nuclear accidents. This work contributes through the development of strategies and analysis methods for two applications: an on-line search for gamma-emitting orphan sources and on-line estimation of the depth distribution of 137Cs. A strategy and analysis method dedicated to the detection of orphan sour
This book hopes to offer an insight into the threats facing the vernacular buildings that survive in the Egyptian Western Desert. It offers a guide to those who wish to get involved in rescuing these buildings, those who re-use them and those who care for them. The first part of the book opens with an overview of the problems experienced in places that are only now becoming vulnerable to the rapid
Restriction Endonuclease Analysis (REA) was used to characterize strains of Lactobacillus plantarum, Lb. pentosus, and Lb. reuteri. This method was shown to be a powerful tool for separation at the species and strain level. RAPD analysis of raw cell abstracts was used to characterize strains of Lb. plantarum. This method was shown to be useful for separation of most strains, and the results were o
Adolescence is a period when teens normally revolt against being dependent. For teens with asthma this period may be even more difficult to deal with, as they also have to deal with their illness. Since few studies describe this phenomenon, the aim of this study was to provide a theoretical understanding of how teens with asthma manage their everyday life in relation to their disease. A grounded t
Surface temperature in internal combustion engines is of high interest when studying heat losses. Two approaches for retrieving the surface temperatures are thermocouples and Laser Induced Phosphorescence, LIP. This study aims to analyze LIP as a technique for measuring surface temperature in internal combustion engines. The motivation for this study is the need for accurate surface temperatures w
The butchering of wild boar during the Mesolithic in South Scandinavia has been studied through the analysis of cut marks on osteological remains from the sites Ageröd I:HC, Ringsjöholm, Tågerup and Bökeberg III in Scania, Sweden. The study reveals relatively high frequencies of cut marks from dismembering and filleting. The distribution of cut marks indicates a uniformity in the dismembering of w
BACKGROUND: Aerosol particles have, since the antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution cause at least 100,000 deaths in Europe each year, whereof 5,000 in Sweden. These figures do not include the outcomes of indoor sources or smoking, which shortens the lives of millions of people worldwide. During recent years especially
Action research brings to the fore questions regarding both the power over knowledge building and, consequently, questions on the quality of knowledge. Action research makes visible two dimensions that in this regard are significant. First, the dimension outside-inside where action research more than traditional research voice an inside perspective. This means that those on whom research is conduc
Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Results from a research field monitoring program by daily resistivity measurements in Sweden clearly show long term changes in resistivity in the embankment dam. The results indicate that resistivity monitoring ca
All higher functions of the cell are dependent on cell signaling. It is the way of the cell to obtain information about the world surrounding it. By getting information on e.g. temperature, glucose concentrations, or the density of neighboring cells, the cell can make decisions on how to optimally act given the supplied information. Even though cells are very different, some of the basic mechanism
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for skeletal metastases is based on data from 16 randomized trials. Moreov
Popular Abstract in Swedish I studier rörande de yngsta barnen saknas ofta genusperspektiv. Ett syfte med studien var därför att undersöka interaktionen mellan barnen (1-3 år gamla) och förskolepersonalen på småbarnsavdelningarna vid tre förskolor i ett genus- och kontextuellt perspektiv. Ett annat syfte var att undersöka pedagogernas föreställningar om barn och genus. Ett tredje syfte var att disIn studies concerning the youngest children, the toddlers, the gender perspective is often missing. One aim of the study was, therefore, to investigate the interaction between children and preschool teachers in day care centres in a gender and a contextual perspective. Another aim was to investigate the inner representations of the preschool teachers concerning children and gender. A third aim was
OBJECTIVE: We have compared the effectiveness, time required for de-airing, and safety of a newly developed de-airing technique for open left heart surgery (Lund technique) with a standardized carbon dioxide insufflation technique. METHODS: Twenty patients undergoing elective open aortic valve surgery were randomized prospectively to the Lund technique (Lund group, n = 10) or the carbon dioxide in
