Popular Abstract in Swedish Mykorrhiza är symbiosen mellan växters rötter och olika svampar. När en symbios har etablerats i en rot växer svampens mycel ut i marken och tar där upp näring som levereras till växten. I denna avhandling studerades hur man kan mäta detta mycel i marken med hjälp av biokemiska markörer. Vidare studerades hur detta myces påverkar övriga mikroorganismer i marken.The interactions between external mycorrhizal mycelia and saprophytic microorganisms were studied in experiments with growth chambers specially designed to enable the mycelia to develop in root-free soil compartments. The growth of the mycorrhizal mycelia was estimated by use of biochemical signature compounds. It was shown possible to estimate the biomass of the external mycelium of different ar

Popular Abstract in Swedish Ämnet för den här avhandlingen är tillverkning och studier av elektroniska komponenter tillverkade av mycket små tråd- och punktformade byggmateriel. Diametern hos en sådan tråd kan vara så liten som 1 nanometer, vilket motsvarar en miljondels millimeter. När komponenter krymps till de här ytterst små dimensionerna uppstår nya fenomen, och parametrar som kan tyckas varaThis thesis describes novel methods for the fabrication of nanometer-scale electronic devices, such as single-electron transistors and resonant tunneling diodes, from wire- and dot-shaped building blocks. The first part of the thesis describes the manipulation of metal nanoparticles and carbon nanotubes using an atomic force microscope. Single-electron transistors were realized by moving nanotubes

Bohemia and Moravia, today part of the Czech Republic, was the first territory with a majority of non-German speakers occupied by Hitler’s Third Reich on the eve of the World War II. Tens of thousands of Jewish inhabitants in the so called Protectorate of Bohemia and Moravia soon felt the tragic consequences of Nazi racial politics. Not all Czechs, however, remained passive bystanders during the g

Popular Abstract in Swedish Östersjön är ett grundhav med tillförsel av saltvatten från havet och sötvatten från omgivande floder. De två vattenmassorna är vertikalt skiktade, vilket resulterar i en estuarin cirkulation, vilken har genomgått stora förändringar till följd av landhöjningen efter senaste nedisningen. För att kunna rekonstruera havsmiljöers förändringar bakåt i tiden är det nödvändigtThe Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin. For researchers to understand past changes in the marine environment of the Baltic Sea, a soun

Fortresses, Storehouses and Symbols - ambiguous churches of the Baltic Sea: Källa on Öland is used as a point of departure in a discussion of the so-called defensive churches or multi-functional churches at the Baltic Sea. The categorization of medieval society into four separate spheres, the church, the castle, the town and the countryside, is criticised as having created a heterogenous group of

Popular Abstract in Swedish Syftet med denna avhandling var att undersöka olika aspekter på intersubjektivitet, metakognitiv utveckling och mellanmänsklig förståelse. Mer precist var syftet att undersöka hur några specifika teorier – mentaliseringsteorin, teorin om primär intersubjektivitet, samt interaktionsteorin – beskriver vilken roll intersubjektivitet har att spela i denna utveckling. De förThe aim of the thesis was to examine different aspects of the role of intersubjectivity in metacognitive development and in social understanding. More specifically, it investigates how different theoretical frameworks, such as mentalization theory, the theory of primary intersubjectivity, and interaction theory describe the developmental role of intersubjectivity. The suggestions these theories ma

In stochastic time-frequency analysis, the covariance function is often estimated from only one observed realization with the use of a kernel function. For processes in continuous time, this can equivalently be done in the ambiguity domain, with the advantage that the mean square error optimal ambiguity kernel can be computed. For processes in discrete time, several ambiguity domain definitions ha

The human genome, in common with all mammalian genomes, carries a high load of inheritable retroviral sequences. We have identified and characterized a novel family of these endogenous retroviruses and have named this family HERV-F as based on the primer binding sites of three members. The HERV-Fs are C-type endogenous retroviruses that have unique gag, pol and env regions that are, based on phylo

Popular Abstract in Swedish Störningar i händernas finmotorik, kraft och känsel är vanliga symtom efter långvarigt bruk av handhållna vibrerande verktyg. I gynnsamma och lindriga fall kan dessa besvär gå tillbaka efter upphörande av expositionen för vibrationer. I mer avancerade fall tilltar besvären och ett hand-arm vibration syndrom (HAVS) utvecklas. Detta tillstånd utgör ett av de allvarligare Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. The general purpose of this thesis was to test the hypothesis that vibration exposur
