With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. This thesis considers disordered/ordered inte
The round goby, Neogobius melanostomus, is a recent intruder of the Baltic Sea, which presumably arrived via the ballast water of travelling ships. The establishment of self-sustaining populations in this ecosystem has had both negative and positive effects on the native species composition within the area. Competition over resources and shelter, spawning interference, and the predation on native
Chocaya Basin ligger i den nordvästra delen av dalen Cochabamba i Bolivia, där ett halvtorrt klimat råder. Den ökande befolkningen är beroende av lokala akviferer för dricksvatten och jordbruk, där brunnar används för att utvinna vattnet. Låg nederbörd, främst under torrperioden, och uppförandet av nya hus eller fabriksbyggnader, påverkar infiltrationen av vattnet i jorden och därmed akviferernas The Chocaya Basin is situated in the north-western part of the Valley of Cochabamba, Bolivia, where a semi-arid climate prevails. The increasing population is dependent on local aquifers for drinking water and irrigation. Wells are used to extract water. Scarce amount of rainfall, mainly during the dry season, and constructions of buildings, are reducing the infiltration of water in the soil and c
An aim with this master thesis is to evaluate when, according to Swedish building code, design of structural fire protection can be carried out using a localized fire as the design fire, i.e. to determine when flashover is not likely. Another aim of the thesis is to examine how a structure is globally affected by a local failure due to a localized fire. One of the goals is to develop a method that
Sverige elektrifierar i snabb takt, vilket driver en stor energiomställning där förnybara energikällor som vind- och solkraft spelar en nyckelroll. Dessa medför väldigt lite koldioxidutsläpp och är ett nödvändigt steg mot ett mer hållbart samhälle. Men är det verkligen så enkelt som att bara bygga mer vind- och solkraft - och kan vi förvänta oss samma robusta och pålitliga elförsörjning som vi tidThe electric power system is undergoing a major change through the implementation of a large number of variable renewable energy sources (VRE), driven by the goal to reduce carbon-dioxide emissions from electricity production. This transition increases the need for a more flexible and dynamic power system capable of maintaining voltage and frequency stability under changing operating conditions. U
This thesis aims to describe, analyze and evaluate how the local government policies accommodate housing segregation in neighborhoods of Malmö, Sweden. This is done mainly through an analysis of material collected from documents and interviews, to a large extent concerning a recently built area within Malmö: Limhamns Sjöstad. Through a theoretical framework based on neoliberalism and the locally p
In Nampula Province, Mozambique, locating productive wells is a problem due to the heterogeneity in local geology, which consists of mainly weathered crystalline rock. This study estimates hydraulic conductivity of 10 hand pumped water wells in rural areas of Nampula Province using slug tests, and is a follow up of Andersson and Björnström (2013) and of Enkel and Sjöstrand (2013). This thesis aim
Uppsatsen behandlar kommunal delegation och speciellt den myndighetsutövning mot enskild som sker på socialrättens område. Framförallt gäller myndighetsutövningen tvångsomhändertaganden och ansökan om tvångsvård enligt LVU. Uppsatsen består av en deskriptiv del där gällande rätt avseende kommunal delegation utreds. Begrepp som behandlas är bland annat ren verkställighet, beslut, lekmannastyrning, This thesis deals with municipal delegation and in particular the excercise of authority over individuals within the field of social law. Said exercise of authority primarily concerns compulsive preventive detention and applications for compulsory care under LVU. The thesis consists of a descriptive part where the applicable law regarding municipal delegation is investigated. Concepts covered incl
The industrial food production system have given rise to tens of thousands of local, national and international social movements concerned with food and agriculture, reacting to the perceived social and environmental failures of the industrial food system. One of the directions inside these movements is the internationally based “local food” movement. The ”local food” movement promotes small-scal
Forest biomass acts as an important indicator of carbon resources in terrestrial system. Estimation of forest biomass enables a straightforward measurement of carbon storage and provides initial values for process-based carbon cycle models to simulate carbon dynamics. LiDAR (Light Detection and Ranging) remote sensing is increasingly used to estimate forest biomass because of its ability to detect
The purpose of this study is to understand and gain insights into the entrepreneurial marketing experiences of female immigrant women in the Helsinki metropolitan area. There is limited literature on immigrant entrepreneurs in Finland and even less regarding female immigrant entrepreneurs, thus it is important to investigate this subject matter. A qualitative research method is adopted, through t
Contactless palmprint recognition is a biometric technology which due to its ease of acquisition, non invasive nature and potentially cheap cost can come to stand competitive to more widely used biometric traits such as finger- or facial recognition. This work uses two different feature extraction methods for palmprint images, the Scale invariant feature transform (SIFT) with an iterative random s
Tourism is one of the fastest-growing economic sectors in the world. Due to that, many developing world’s regions with limited economic activity adapt tourism as a development strategy. The point of departure is a critical consideration why tourism, while producing such immense economic benefits, frequently also perpetuates already existing socio-economic, cultural, and environmental dysfunctions.
Today’s climate crisis entails a need to change our ways of living, where an important aspect of meeting climate goals is a switch to renewable energy production. This bachelor thesis aims to explore the renewable energy transition, through a qualitative case study of a Swedish municipality in which southern Sweden’s biggest wind power park is being built. The research questions are on which geogr
The purpose of this study is to contribute to the limited literature on sustainable consumption in Vietnam with a focus on the young urban consumer. Sustainable consumption is an important area to focus on as Vietnam is an emerging economy with a young population where consumption is increasing and where the young and fast-growing labor market underpins their economic prosperity. Vietnam is also e
Shabestar basin in the East Azerbaijan province, Northwest Iran, where irrigation is the main groundwater consumer, has experienced large-scale subsidence and groundwater deletion, which poses a threat to the local agricultural activities, economic development, and food security. With the emergency of mitigating the risk, satisfying future demand for groundwater, and improving resilience consideri
Sediment sequences spanning the last 800 years from two small lakes in the south Swedish uplands were explored for assessment of effects of changing human population, local land-use practices and airborne pollution on lake-ecosystem functioning and resilience. Variations in nutrient cycling and deposition of lithogenic elements were studied, using a multi-proxy stratigraphic approach. Carbon and n
We report on the magnetization depth profile of a hybrid exchange-spring system in which a Co/Pd multilayer with perpendicular anisotropy is coupled to a CoFeB thin film with in-plane anisotropy. The competition between these two orthogonal anisotropies promotes a strong depth dependence of the magnetization orientation. The angle of the magnetization vector is sensitive both to the strength of th
Background and purpose The remodeling of morselized bone grafts in revision surgery can be enhanced by an anabolic substance such as a bone morphogenetic protein (BMP). On the other hand, BMPs boost catabolism and might cause a premature resorption, both of the graft and of the new-formed bone. Bisphosphonates inactivate osteoclasts and can be used to control the resorption. We studied a combinati
