Popular Abstract in Swedish Catecholaminerna dopamin, noradrenalin och adrenalin är en grupp transmittorsubstanser som är involverade i olika funktioner i det centrala nervsystemet. De olika catecholaminerna bildas med hjälp av specifika enzymer. Tyrosin hydroxylas (TH) omvandlar L-DOPA till dopamin (DA), som i sin tur omvandlas av enzymet dopamin ß-hydroxylas (DBH) till noradrenalin, som till sisCatecholamines, comprising the neurotransmitters dopamine (DA), noradrenaline (NA) and adrenaline (A) are synthesized by specific enzymes (tyrosine hydroxylase (TH), dopamine ß-hydroxylase (DBH), phenylethanolamine-N-methyltransferase (PNMT)) in the central nervous system. The development and distribution of different catecholaminergic systems have been described in both the brain and retina of th

Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of

Substantial genetic variation is hypothesised to be necessary for the long-term survival of species. Therefore, a major aim in conservation is to maintain and restore variation in small and endangered populations. However, in most populations the amount of genetic variation and, thus, the potential threats posed by limited variation are unknown. In the present study, we assess genetic variation, b

Popular Abstract in Swedish Det har blivit vanligt med beskrivningar av hur olika trender påverkar det sätt på vilket arbetslivet utformas. I första hand rör det sig om informationsteknikens inflytande inom i stort sett alla samhällsområden men det handlar också om en globaliserad ekonomi, ökad konkurrens, samt strävan efter högre kvalitet och större flexibilitet. Denna utveckling kan förstås som The study explores the interaction of general management ideas like TQM (here referred to as technocratic visions) and microprocesses of narrating and organizing in two different contexts: the public sector (health care) and the private sector (manufacturing) in Sweden. The purpose is to provide a better understanding of what happens when models of this type are introduced into a work organization

The poor healing capacity of the anterior cruciate ligament and the development of postoperative adhesions, restricting tendon gliding, are two important clinical problems regarding different, although related, aspects of posttraumatic connective tissue reactions. The aim of this study was to gain more knowledge about the process of ligament and tendon healing at the cell and molecular levels and

Popular Abstract in English The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where most steel sheet pile walls have cap beams of reinforced concrete. The degradation processes of these structures must be taken into account both when designing new structures and when inspecting The two most used building materials in harbor structures are undoubtedly steel and concrete.

The influence of grain boundaries on the mechanical properties of poly-crystalline metals is well known. Here we investigate the influence from a centrally placed grain boundary in nano-sized beams of Cu subjected to tensile loading. The crystallographic orientations in the grains are [100], [110] and [111]. The investigation is performed by means of molecular dynamic simulations employing the mol

Experimental data on single file pedestrian movement has been analysed andimplemented in a prototype movement model. The prototype model is developed topredict movement of persons based on a first principle approach using basic populationdata such as age, height, gender and response time to adapt the walking speed in a crowd.The experimental data provide the biomechanical information needed in the

Why did heraldry originate? This question has often been answered with references to changes in the military equipment in the 12th century, especially the introduction of the closed helmet. But recent research gives reason to question this theory. The introduction of the closed helmet and the origin of heraldry did not coincide chronologically. There are other changes in the military equipment, an

On Friday June 10 2016, the Center for Middle Eastern Studies (CMES) at Lund University arranged a seminar devoted to explore refugee experiences among Syrians in the Öresund region. Organizers were CMES researchers Dalia Abdelhady and Joshka Wessels. Lund University and international researchers in law, religious studies, refugee studies, environmental studies, urban sociology and anthropology pa

There is a lack of objective evaluative standards for academic work. While this has been recognized in studies of how gatekeepers pass judgment on the works of others, little is known about how scholars deal with the uncertainty about how their work will be evaluated by gatekeepers. Building upon 35 interviews with early career academics in political science and history, this paper explores how juThere is a lack of objective evaluative standards for academic work.

Nanoindentation is a useful experimental method to characterize the micromechanical properties of materials. In this study molecular dynamics and peridynamics are used to simulate nanoindentation, with a spherical indenter targeting a thin single crystal Cu film, resting on an infinitely stiff substrate. The objective is to compare the results obtained from molecular dynamic simulations to those o

At temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season. Thus, energy costs of thermoregulation might constrain nestling growth, and low nocturnal temperatures might require resources that parents could otherwise have invested into nestlings during the day. To manipulate parental work rate, we performed brAt temperate latitudes, altricial birds and their nestlings need to handle night temperatures well below thermoneutrality during the breeding season.

According to a recent conjecture in the literature, earnings have become a poorer proxy for cash flow from operations over time. We find that since 1988, when cash flow statements started to be consistently reported in Compustat, the cash effectiveness of earnings has actually increased for a large sample of US manufacturing firms. This occurs despite the introduction of fair value accounting and

This article aims to investigate how articulations of women’s relation to the welfare state and modes of political agency has changed in Sweden between 1977 and 2017; a period characterized by the introduction and implementation of a neoliberal political rationality. By way of discourse analysis, the article highlights the reciprocal relationship between the construction of the welfare state and w
