The paradoxes induced by unrestricted self-reference have been of interest since antiquity. In this paper the author approaches the interpretation of self-reference in natural languages from the perspective of linguist - using as insight the treatments of self-reference by Russel, Tarski, Kleene and Scott. The subject of self-reference is approached historically. The works of Russell are first dis
This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. Finally, an experimental apparatus for investigations of lubricants at high pressures is presented. The design of hydrodynami
There is an increasing demand from students and their organisations all over Europe for involvement in quality assurance. Today, this demand is met with a wide international understanding that student involvement is a key factor in quality assurance. Student representatives and organisations are involved in the development and execution of quality assurance processes in many higher education insti
This paper presents results for vehicle-to-vehicle channel characterization based on measurements conducted for the merging lane scenarios on a highway. We present power delay profiles as well as channel gains and analyze important propagation mechanisms to see the impact of line-of-sight (LOS) and the antenna radiation pattern on the total received power. It is found that the absence of LOS and s
A crucial step in many biochemical studies is the separation and purification of the individual structures of interest. For cells, cell organelles, and membrane fragments, the use of aqueous two-phase partition has become an important tool. The basis for separation in these phase systems is the surface properties of the material, and the method, therefore, nicely complements the more traditional c
Popular Abstract in Swedish Av pedagogiska skäl har anförts att det finns behov av mer kunskaper om människans tänkande om och förhållningssätt till munhälsa och tandvård. Syftet med denna undersökning var att undersöka och beskriva vuxna människors subjektiva tänkande om och förhållningssätt till munhälsa för att belysa faktorer som bidrar till eller utgör hinder för förändring av handlingsberedsThe need, for health educational reasons, of obtaining a more adequate understanding of how people think and act in connection with questions of dental health and professional dental care has been emphasized. The present study examines the attitudes and conceptions of adult individuals regarding their own dental health, as well as measures they take to further it. The aim is to elucidate factors t
A new method for extraction of general features in ECGs with atrial tachyarrhythmias is presented. The method is based on our recent method for atrial signal characterization which sequentially decomposes a time-frequency distribution into a set of parameters. In addition to rate and amplitude, the method tracks information on regularity, waveform, and structure of the atrial signal. The proposed
This paper introduces a research project with the aim to develop concepts and tools for architectural design, taking the ideas of "behaviour settings" as a starting point, to enable a more relevant holistic view in object oriented design of buildings. In this paper we introduce the concept of "architectural object" as a representation of a real "situation" involving people, behaviour, experience a
This is the third annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish
People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application running on the Android platform in which a user may scan for map in
The interaction between DNA and cationic cosolutes- multivalent ions, cationic surfactants and cationic macromolecules- has direct biological implications and is also foreseen to have a number of applications, in particular for transfection and protection and purification of DNA. We have during the last few years established a broad physico-chemical research program on various mixed systems of DNA
