Popular Abstract in Swedish Bestrålning av allmänheten från radioaktivt cesium efter Tjernobylolyckan. Fältstudier i ett högkontaminerat område i Bryanskregionen i Ryssland. Olyckan i kärnkraftverket i Tjernobyl i Ukraina 1986 orsakade att stora delar av Europa kontaminerades med radioaktiva ämnen, varav 137Cs är det som fortfarande finns kvar pga sin långa halveringstid (30.2 år). BryanskområdetFrom 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0.9-2.7 MBq m-2. Yearly

Popular Abstract in Swedish Denna avhandling är inriktad på metoder för att förbättra och utvärdera infrastrukturer för geografiska data (eng. Spatial Data Infrastructure). Syftet har varit trefaldigt: att utveckla ett ramverk för hantering och utvärdering av en infrastruktur, att förbättra tillgängligheten av geografiska data i en infrastruktur, och för att förbättra kartografi i visningstjänsterThis thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI. Spatial Data Infrastructure has been identified as an umbrella covering spatial data

Popular Abstract in Swedish Vibrationsskador utgör idag ett av de största yrkesmedicinska problemen. Hälften av dem som arbetar med handhållna vibrerande verktyg får besvär från händerna på grund av skador på blodkärl och nerver. Nervskadan yttrar sig som domningar och stickningar i fingrarna med fumlighet och svaghet i handen. Skadan är allvarlig eftersom symptomen kan leda till försämrad handfunThe aim of this study was to investigate clinical, pathophysiological and structural aspects of vibration-induced peripheral neuropathy since work with hand-held vibrating tools may lead to progressive neurological and vascular hand symptoms. Symptomatic vibration-exposed men were examined clinically and by neurography, tactilometry, and vibrometry and by measurement of temperature perception thre

A model of scattering of three one-dimensional particles is constructed by means of the extension theory of selfadjoint operators. The dispersion equation for the three-particle bound state energy is obtained and an exact mathematical expression for the corresponding wave functions is derived

The study examines from a cultural analysis perspective how habilitation training can learn adolescents who use wheelchair to become more integrated in urban environments. The wheelchair is considered in this study mainly as an emancipator. A specific habilitation training, called “Wheelchair in the city”, is studied, that teaches adolescents to overcome the obstacles they meet in urban environmen

Given the uncertainty and complexity of security risk analyses, there is a great need of tools for contextual inquiry supporting assessment of risk with multi-value scales according to different stakeholders’ point of view. Such tools can be used at individual level to help develop the understanding of a problem space. At the collective level, they can be used as a mean of communication to support

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that (1) moral sentences have truth-value (cognitivism), (2) there are moral properties that make some moral sentences true (success-theory), and (3) moral properties are not reducible to non-moral properties (non-reductionism). Realism is contrasted with non-cognitivism,

Handheld computing and mobile information systems are continuously breaking new ground, with an increased importance for business. However, there is evidence that we still have lessons to learn concerning the design of handheld information systems. Handheld information system poses challenges to the designer in the unique properties of handheld technologies and the conditions of use of handheld te

For ergonomics/human factors solutions to be beneficial for society and its members it is vital to apply a systems level perspective. Students who will be the future engineers, designers, and managers of socio-technical systems need to gain an understanding of how ergonomics/human factors can be integrated in the design of workplaces, organisations, products, and services. This paper gives example
