Abstract We live in a world today that is characterized by the Internet. We can get hold of people on the other side of the globe whenever we want and we can purchase what ever we want, from who ever we want, anytime we want. This development has made it important to find systems of dealing with the payment in a safe and secure way, both for a private person as well as for a company, when you do t
Two methods of computational analysis of DNA barcodes are presented. A DNA barcode is formed by making GC-rich regions of a DNA molecule fluoresce while AT-rich regions remain dark, thus when stretched using nano-channels and viewed in a microscope, the DNA molecule will resemble a barcode with black and white stripes. Because of point-spread functions and pixellation the resolution will be roughl
The Greenhouse Gas Reduction Mandate (GGRM, reduktionsplikten) is Swedish legislation focused on reducing carbon emissions by mandating that the emissions of certain fuels are reduced by a specified percentage, that percentage increasing each year. This paper investigates the rationale behind a political drive to decrease the GGRM, the cost-effectiveness of the GGRM, and the consequences of t
This thesis evaluated the performance of the water balance model BROOK90 for an even aged spruce forest in southern Sweden. The water balance of the forest was modelled from 1950 onwards to find periods and patterns of drought. Moreover, the impact of climate change as well as thinning as a strategy to reduce drought stress on the water balance were evaluated. Hyltemossa, a managed Norway spruce f
Popular Abstract in Swedish Avhandlingens syfte är att söka kunskap om vilka faktorer som bidrar till uppfostringsanstaltens framgång som social institution och dess ständiga misslyckande som behandlingsorganisation. Jag försöker förstå varför organisationer som §12-hem och särskilda ungdomshem finns och vilken betydelse de har i vårt samhälle. Svaret på den frågan söker jag på tre sätt: genom attThe aim of the present study is to find the factors and conditions that generate the success of the reformatory as a social institution and, at the same time, its well-known failure as a treatment organization. I try to understand why organizations like the reformatory exist and what meaning they have in our society. I seek answers by exploring the birth of the reformatory in a historical perspect

Three studies investigated decision makers' memory representations of choice alternatives in most important real-life decisions. In Study 1, each participant recalled the most important decision that she or he had ever made and rated to what degree a number of characteristics could describe the decisions. In Study 2, the participants were asked to think about an important decision that they had ma
Popular Abstract in Swedish Proteiner är nödvändiga beståndsdelar i en levande cell. Dels bygger de upp viktiga strukturer och dels katalyserar de kemiska reaktioner. Proteiner kodas av gener. Varje protein motsvaras av en gen. Vägen från gen till protein är densamma i alla organismer på jorden. Först transkriberas en gen till en molekyl kallad mRNA (budbärar-RNA, eng. messenger RNA). Detta mRNA aDegradation of mRNA is a controlled process which is as important for gene regulation as the synthesis of mRNA. This thesis focuses on mechanisms of mRNA stability and degradation in Bacillus subtilis, the model of Gram-positive bacteria. The aprE mRNA, encoding an exported protease named subtilisin, is extremely stable with a half-life of more than 25 minutes. Average mRNA half-lives in B. subtil
Popular Abstract in Swedish Modellering och krav för automation av gradningsprocessAn increasing number of robots have been used for the finishing of castings during recent years. This is mainly due to developments to overcome problems that restricted their use during the past decade. The major difficulties have been the need to control reaction forces during metal removing by grinding operations and the lack of tools designed specially for robots. The elimination of these two p
Many ectothermic species are currently expanding their distributions polewards due to anthropogenic global warming. Molecular genetic mechanisms facilitating range expansion under these conditions are largely unknown, but understanding these could help mitigate expanding pests and disease vectors, or help explain why some species fail to track changing climates. Here, using RNA-seq data, we examin
This thesis comprises general parametric models for surface roughness. The models can be used in several technical and natural applications but are here only applied to the micro-structure of paper. In that application, earlier models are generalized and new models introduced. The different models are related to the scale of the roughness and by using different approaches, different roughness prop
Background: Mechanical ventilatory support seriously affects speaking and communication, and earlier studies show that many ventilator-supported patients experience difficulties and frustration with their speech and voice production. Since there is a growing number of individuals who require mechanical ventilatory support and there is a paucity of studies that examine ventilator-supported communic
The formation of planetary cores must proceed rapidly in order for the giant planets to accrete their gaseous envelopes before the dissipation of the protoplanetary gas disc (less than or similar to 3 Myr). In orbits beyond 10 AU, direct accumulation of planetesimals by the cores is too slow. Fragments of planetesimals could be accreted faster, but planetesimals are likely too large for fragmentat
Popular Abstract in Swedish Personer med insulinbehandlad diabetes saknar, eller har kraftigt försämrad, kroppsegen förmåga att reglera blodsockernivån genom utsöndring av hormonet insulin, och måste därför ta flera injektioner insulin dagligen. De flesta injektioner tas i samband med måltid, och individen bestämmer normalt sina måltidsdoser utifrån aktuell blodsocker- och hälsostatus i kombinatio
Popular Abstract in Swedish Hawaiianernas liv och historia har dokumenterats allt sedan första kontakten med västerländska äventyrsresanden i slutet av 1700-talet. I samband med amerikanska missionärers ankomst år 1820 introducerade och etablerade dessa missionärer en puritansk lära och kunskapsförmedling via det skrivna ordet. Mötena mellan de olika kulturerna har beskrivits som fredliga. Dock haThe life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri
There are two levels to this thesis, the examination of the particular case and the exposition of the general approach. The case the thesis deals with is Louisiana’s coastal land-loss crisis and what can and should be done about it. I examine the current approach to coastal protection and restoration in the state of Louisiana, drawing on different economic theories of sustainable development and c
Avhandlingen består av tre oberoende kapitel som alla är empiriska studier av forskare och den roll som olika typer av rörlighet spelar för att forma forskarnas vetenskapliga produktion och karriär.Kapitel 1 studerar effekterna av avregleringen av svensk arbetsmigration, 2008, på publiceringsproduktiviteten hos akademiker verksamma i Sverige.
