The evolution of dispersal was investigated in an adaptive individual-based metapopulation model, which allowed for demographic and environmental stochasticity. The individual dispersal behaviour was determined by a one-locus genotype subjected to simple inheritance and mutation. Dispersal behaviour could therefore evolve through the genotype–phenotype mapping and the selection regimes stemming fr
This study investigates the genetic structure of an eukaryotic microorganism, the toxic dinoflagellate Alexandrium ostenfeldii, from the Baltic Sea, a geologically young and ecologically marginal brackish water estuary which is predicted to support evolution of distinct, genetically impoverished lineages of marine macroorganisms. Analyses of the internal transcribed spacer (ITS) sequences and Ampl
Calcitonin gene-related peptide (CGRP) and nitric oxide (NO) are two molecules shown to have a role in migraine pathophysiology. Our objective was to test the hypothesis that migraine subjects are particularly sensitive to these signal molecules. The cutaneous microvascular responses to endothelial and non-endothelial dependent dilators were tested using laser Doppler flowmetry in combination with
Square cross-section ribbed channels with deflectors are computationally simulated to determine their optimal configuration for enhancing heat transfer with minimized pressure drop penalties. In this study, the channel inlet Reynolds number ranges from 8,000 to 24,000. The influence of deflector arrangement on the overall performance characteristics of ribbed channels is investigated with six diff
The problem addressed in nonlinear dimensionality reduction, is to find lower dimensional configurations of high dimensional data, thereby revealing underlying structure. One popular method in this regard is the Isomap algorithm, where local information is used to find approximate geodesic distances. From such distance estimations, lower dimensional representations, accurate on a global scale, are
The need for land security continues to be urgent for economic development in Africa. Central governments are implementing large-scale land reforms, yet the effects of land title formalisation are still not thoroughly understood. The growing evidence by macro-level empirical studies of the importance of property rights has not been sufficient for understanding the factors that determine property r
Purpose: The aim of this dissertation is to explore mobility in a proximity tourism context. Mobilities are being widely discussed in connection to society, everyday life, and tourism as a whole. Thus, it focuses on the staycation phenomenon as a case of proximity tourism. In particular on its representations in the digital media and as a local travel practice in Sweden. Considering that tourism i
2013 beslutades att Fritidsbadet i Ystad var i för dåligt skick för att fortsätta vara badhus och kommunen valde därför att permanent stänga badet. Samma år utlystes en markanvisningstävling för byggnaden med målsättning att hitta en ny användning för Fritidsbadet som funnits sedan 1961. Förslaget som vann och började realiseras 2017 ville göra badet till ett hotell och konferenscenter, vilket ja2013 it was concluded that Fritidsbadet in Ystad was in too bad condition to continue to be a public bath and the municipality decided to permanently close it. The same year an architecture completion was announced and the goal was to find a new use for Fritidsbadet that was built 1961. The winning proposal, that started to become realized in 2017, wants the bath to become a hotel, which I as a lo
Spurred on by pressure to find sustainable energy production alternatives to fossil fuels, many industries have been acquiring land in order to plant crops for biofuel production. In Tanzania, biofuel development is in an early stage, and over the last decade, several foreign actors have tried to start up biofuel projects in the country (without success). Land acquisitions are seen by many as a fo
In this thesis we investigate the level of deliberative democracy in the current implementation of the 24/7 Agency in the local government. We are interested in how the combination of the two seemingly opposing ideals of Demokratiutredningen and the 24/7 Agency is solved. Our analysis is based on interviews with civil servants from three kommuner in Skåne and a schematic overview of their websites
The aim of this thesis is to investigate why the municipality of Lund has not done more, in relation to LundaMaTs, to inform and promote the purchasing of organic provisions to the public. This is of interest since it is determined in the Rio Declaration and Agenda 21 that the current unsustainable production and consumption patterns need to change. The local authorities play an important role
The river Komadugu Yobe in the Lake Chad basin is a seasonal river, about 370 km long and with an average highest flow of 34 m3/s during the time period of 1957 to 1976. The river is dynamic with plenty of meanders and oxbow lakes along its sides. Komadugu Yobe’s thalweg (the line defining the lowest points in a riverbed) is the natural border between Niger and Nigeria and may change position with
This paper provides a comprehensive understanding the Swedish long stay tourism in Thailand. The motivation approach was the main approach to this research through highlighting the major push and pull factors. The participation involved the total of 120 respondents. To enhance the analysis of the data, both qualitative and quantitative research approaches were employed. The total push factors that
Gender-based violence (GBV) is both a human right violation, a threat to develop-ment and a global health issue. Women with disabilities (WWD) are a group more exposed to GBV. However, research has been scarce about WWD and GBV, espe-cially in the Global South. This thesis studies how local organizations are working on the issue of GBV targeting WWD in Uganda. The theoretical framework em-ployed i
Background. Linear programming has been used extensively as a tool for nutritional recommendations. Extending the methodology to food formulation presents new challenges, since not all combinations of nutritious ingredients will produce an acceptable food. Furthermore, it would help in implementation and in ensuring the feasibility of the suggested recommendations. Objective. To extend the previou
In birds, fat accumulation before and during migration has been shown to be endogenously controlled and tuned by, among other factors, the Earth's magnetic field. However, our knowledge about the influence of the geomagnetic field on the fuelling in migrating birds is still limited to just a few nocturnally migrating passerine species. In order to study if variations of the magnetic field can also
We present the open-source software framework in JModelica.org for numerically solving large-scale dynamic optimization problems. The framework solves problems whose dynamic systems are described in Modelica, an open modeling language supported by several different tools. The framework implements a numerical method based on direct local collocation, of which the details are presented. The implemen
The phenomenon murder, in the name of honor, you can describe in several different ways. The purpose with our work was trying to describe honor related crimes from the investigators perspective. From the valid discourses we were looking for answers about how a social worker understand girls crying for help and what aspects are determine in the judge for a propitiate measure. During our work with t
The Swedish society and welfare model are under constant changes and development. One of the core areas in this welfare model is the social policy. By analysing the changing role of the organizations in the civil society on a local level with a theoretical typology changes in the roles can be noted. These changes can with a model for ideal types raice questions about bigger changes concerning iss
