Climate change is one of the greatest environmental challenges at the present time and is currently an issue affecting the entire global population. Alternative renewable energy sources are vital to be able to deal with this challenge. Solar energy is one of the most promising renewable energy sources and is therefore also one of the fastest growing industries in this field. However, solar energy
During the past, land use has changed and still is. It has been recognized that land use changes affect biodiversity all over the world. In Sweden semi-natural grasslands are a habitat with high biodiversity. The topic of this thesis is how land use change has affected the habitat of semi-natural grasslands in the area around Osby, Scania. For that purpose, semi-natural grasslands in a historical
Approximately a quarter of a million women are diagnosed with ovarian cancer annually worldwide. Identifying the genes involved may ultimately lead to the development of corrective and preventive measures to fight this type of cancer. Next Generation Sequencing is a technology that can reveal the genes central to cancer initiation and development, however the analysis of the data is problematic du
Nature-based solutions (NbS) have proven effective in addressing urban sustainability challenges. This thesis focuses on bridging the gap in NbS short-term interventions, scale, and financial barriers. It examines the instrumentalization and implementation of successful long-term interventions from a policy and urban governance perspective, aiming to inspire cities and identify commonalities. The
Akustophores är rörelse av partiklar/celler under inverkan av ljud. Partikel- och cell separation är en applikation som kan utföras av akustophores. Detta är en viktig teknik eftersom den kan avslöja viktig information om sjukdomar och celler och därigenom förbättra valet av behandling inom sjukvården. Genom att utnyttja ljud, så kan celler och partiklar i en lösning separeras efter deras specifikAcoustophoresis is the migration of particles/cells under the influence of sound. Particle and cell separation is an application that can be performed by acoustophoresis. This is an important technique since it can reveal important information about diseases and cells and thereby possibly improve the choice of treatment in healthcare. By utilizing sound, cells and particles in a suspension can be
Despite policy efforts to reduce waste and to recycle material, household waste in Europe continues to grow. In Sweden, most 290 municipalities use volume-based tariffs for household waste management. This report is about two alternative policies for household waste: (1) a weight based waste system and (2) a system of kerbside containers for sorted waste (FNI). It is a case study of policy develo
The purpose of the study was to capture a number of views on what impact language has on integration processes and social life. Since language is an important component of communication amongst people, it affects several aspects of everyday life such as occupation and social participation. To accomplish the aim eight people of foreign origin with experience of studying the language education progr
Statistical comparison of single cases to small samples is a methodology that has been extensively used in, for example, cognitive and clinical neuropsychology. This is most often done to determine changes in cognitive processing after an individual has incurred some type of brain damage. In a clinical setting one often wish to infer whether a patient exhibit abnormally low performance on some cog
The purpose of the thesis was to study the safety and reliability requirements in the automotive industry from a production test perspective. A survey of the requirements in the automotive standard AEC-Q100 was conducted and the implications of compliance with the requirements were analyzed. In addition to this, production data was reanalyzed considering the requirements found in the survey. From
In any storage ring or synchrotron based light source one of the most important factors for generating light with desirable properties is the electron beam itself. The dynamics of the beam must be properly characterised and, ideally, adjusted to the desired values for the light source to be able to deliver radiation of the quality which was decided during its design. This thesis is limited to som
Our world is experiencing accelerated ecological destruction and social injustices on different scales and multiple levels. Unchecked economic growth has been criticised as causing this since the 1970s, but the dominant sustainable development paradigm has perpetuated the belief that economic growth and environmental protection can go hand-in-hand. In response degrowth has emerged in the last deca
Introduction: This study is focused on the development and comparison of different extraction methods for vitamin D (VD) analysis in liver samples. Background: VD deficiency is related to several diseases, so it is crucial to correctly detect and quantify its concentration in the human body. Despite the existing methodologies for VD analysis, the selectivity and the sensitivity of the methods for
The impact that anthropogenic micropollutants have on the environment is increasingly gaining attention. As a result of this, Sweden, among other countries, is looking towards implementing advanced treatment for micropollutant and pharmaceutical product removal from wastewater prior to discharge into the environment. The leading method to achieve this is ozonation, which unfortunately also creates
Eftersom människor tillbringar större delen av sin dagliga tid inomhus idag, ökar intresset och användningen av system för inomhusmiljöer, så kallade inomhuspositioneringssystem (IPS). De senaste åren har det därför tillkommit nya dataformat för inomhuskartläggning och kommersiella IPS och har ännu inte studerats ingående. Därför ger rapporten en översikt över huvuddelarna i IPS: dataformat för inAs people spend most of their daily time indoor today, the interest and usage of systems for indoor environments, called indoor positioning systems (IPSs), are increasing. The last couple of years, new data formats for indoor mapping and commercial IPSs have been released and they are not yet extensively studied. Hence, this thesis provides an overview of the main parts of IPSs: data formats for i
This thesis is a field study which was conducted for 10 weeks in the regional capital city of Casamance named Ziguinchor in Senegal. By using tools from feminist critical theory and methodology such as participatory observations and feminist in-depth interviews with women organisations in Ziguinchor, the purpose of the thesis is to understand how gender roles affect women and women organisations s
The aim of this thesis work was to investigate and evaluate new possible industrial applications for large welded plate heat exchangers, with heat transfer areas of at least 500 m2. The research has been carried out through thermal design of heat exchangers for a total of nine cases. The nine cases are real-life applications for processes covering the petrochemical, oil & gas, power, and refin
Precise knowledge of the temperature during cutting processes is of high interest as the temperature of a cutting tool dictates the performance, and for the workpiece it controls the quality and integrity of the generated surface. For the first time, in this study, a novel technique has been developed utilizing phosphor thermometry for 2D surface temperature measurement of a cutting tool in metal
