Genom att utvärdera Skochparametern och skapa tre konceptkompressorer har examensarbetet försökt komma till en slutsats om hur bladens längdförhållande påverkar en kompressors verkningsgrad och stabilitet. Skochparametern visade sig fungera mindre bra som ett verktyg och det visade sig att ett lägre längdförhållande innebar en liten minsking i verkningsgrad, men en betydande ökning i stabilitet. The design of an axial compressor is mainly the trade-off between efficiency, stability and cost. A parameter that affects all of these three aspects is the blade aspect ratio. Due to the intricacy and complexity of the flow in a compressor, solely the effect of the blade aspect ratio variation is difficult to obtain. A parameter that supposedly is a gauge of the combined airfoil and end wall loa

Huntington’s disease is a hereditary neurodegenerative disease caused by an expansion of CAG repeats in the huntingtin (HTT) gene. HD is fully penetrant around 40 CAG repeats and is characterized by motor impairments, psychiatric disturbances and cognitive deterioration. Unintended weight loss is also a clinical feature of HD, leading to reduced morality and a decline in quality of life in HD pati

This paper examines the effect that aid and foreign direct investment have on poverty by assessing both their separate and interactive effects. We used a Generalized Method of Moments to analyse 107 countries during the time period 1987-2014 and measured the effects of aid and foreign direct investment as growth of inflow per capita. Our result indicates that separately growth in aid and in foreig

En bättre förståelse över ytproteiner på dendritiska subtyper Av Zackarias Söderlund Immunförsvaret ska se till att kroppen dödar inkräktare såsom virus och bakterier men även kroppens egna celler som omvandlats till tumörceller. Dendritiska celler har en viktig roll i detta då de ständigt skannar sin omgivning och instruerar resten av immunförsvaret om påträffande organismer/celler ska tolereraThe development of vaccines against tumours are gaining increased attraction and one strategy to increase the efficiency of these vaccines is to target the antigen or drug to cell surface receptors on dendritic cells (DC), such as the C-type lectin receptors (CLR). To this end, knowledge of the expression levels of CLR on DC subsets is important and it has been studied in different tissues and blo

Plastic production is only increasing, and it‟s not showing any signs of slowing down. Microplastics are particles smaller than 5 mm, either produced intentionally, or created from items being withered into small particles. Microplastic contamination in marine environments is higher closer to cities, and most of the plastic litter eventually ends up in the oceans.

Svanödlor (plesiosaurier) är en utdöd grupp marina reptiler med en global utbredning. I magregionen hos vissa svanödleskelett förekommer stenar. Syftet med denna rapport är att undersöka från vilken miljö svanödlor hämtade magstenar (gastroliter) och vilken funktion de senare hade. Materialet utgörs av 22 stenar som förmodas komma från en svanödla insamlade från sediment tillhörande den lokala BelPlesiosaurs are an extinct group of marine reptiles with a global distribution. During the Late Cretaceous they inhabited the Kristianstad Basin in northeastern Skåne, which at the time was part of a large-scale archipelago with numerous small islands and peninsulas. Stones have been found in the stomach region of many plesiosaur skeletons but their function is as yet poorly understood. The aim of

Förekomsten av plast i marina miljöer har under de senaste decennierna varit ett känt globalt problem. Flera nedbrytningsprocesser inverkar på plastavfallet, vilket orsakar fragmentering ned till fragment mindre än fem millimeter i storlek – kallade mikroplaster. Målet för denna studie är att öka förståelsen om mikroplaster i marina miljöer där följande frågeställningar bemöttes: Hur stor utbredniThe abundance of plastic in marine environments has been a well-known global problem for the past decades. Multiple degrading processes effect plastic debris, causing fragmentation down to particle sizes smaller than five millimeters – named microplastics. The aim for this study is to extend the knowledge of microplastics in the marine environment by addressing the following questions: How wide-sp

Bekämpningsmedel i akvatiska miljöer, skydd av Skånes dricksvatten genom vattenskyddsområden och möjligheter till förbättring! Ungefär 40 % av Skåne utgörs av åkermark och nationellt sett är användningen av bekämpningsmedel som mest intensiv i denna region. En risk associerad med detta är spridningen av bekämpningsmedel från åkermark till akvatiska miljöer. För stärkt vattenskydd är det viktigt Skåne is the region in Sweden where the application of pesticides is the most intense and around 40 % of the region consists of agricultural land. Studies show the occurrence of pesticides in Skåne’s aquatic environments. One way of protecting drinking water is by implementing water protection areas (WPAs), where risky activities can be restricted or prohibited. The aim of this study was to evalua

EU:s reviderade förnybarhetsdirektiv (RED II) – potential att effektivisera den svenska tillståndsprocessen för vindkraft Vindkraften har stora möjligheter att bidra med en del av lösningen till vår tids största utmaning: klimatförändringen. Vindkraftens utbyggnad och utbredning är dock en fråga som i Sverige är förenad med komplexa avvägningar mellan olika, ofta motstående, intressen. TillståndIn Sweden, wind has been recognized as a necessary power source to fight climate change. But the expansion of wind power is associated with conflicting interests. The permit process to build and operate wind power plants is often described as inefficient and complex, with long lead times. This study investigates possibilities for how the Swedish permit process for wind power can be streamlined.

Background: Under a background of increasingly competitive environment in global sourcing e-tailing industry, companies have an urgent need to improve the performance and obtain more profits. However, there is a lack of research specially conducted for the companies under development. Thereby, it triggers a necessity of researching specific strategies from those companies’ perspective, to have a b

Spx or why bacteria don’t suffer from burnout Bacteria also suffer from stress. In general, any fluctuation in the environment of bacteria can cause stress on them. For instance, too hot or too cold temperature, or changes in the pH. In order to survive, they need mechanisms to cope with it. Most of these mechanisms involve proteins, which can be seen as tools that respond to stress. In the bac
