Potentiella miljörisker med geoenergisystems temperaturpåverkan i mark och grundvatten

Geoenergisystems temperaturpåverkan i miljön – en allt hetare fråga Geoenergisystem kan användas för att utvinna eller lagra energi i mark. Energin från marken bidrar inte med växthusgasutsläpp och räknas som förnybar. Energi kan också lagras, och möjliggör på så sätt hushållning med energi! Utvinning eller lagring av energi i mark kan ge upphov till att temperaturförändringar uppstår i marken. DThe aim of this literature study was to answer whether the thermal impact of geothermal energy systems pose a potential environmental risk to groundwater quality and microorganisms in the sub surface and to above ground vegetation. This study shows that the thermal impact of high temperature systems operating with temperatures ≥25⁰C in groundwater could lead to adverse effects on groundwater chemi

Bullerreducerande beläggningar

Bulleremission från vägtrafik är på många ställen i Sverige ett påtagligt problem. Många fastigheter och rekreationsområden ligger så nära vägnätet att de utsattas hälsa och livskvalitet riskerar att försämras vid långvarig exponering. Att åtgärda bullerproblematiken direkt vid källan med en lågbullerbeläggning är idag en stor strävan på många platser. Detta ef-tersom de traditionella åtgärderna sNoise from road traffic is a significant problem in many places in Sweden. A lot of properties and recreational areas are so close to the road network that the health and quality of life of the exposed are at risk of deterioration. Addressing the noise problem directly at the source with a low noise road surface is a great endeavor in many places today. This is because the traditional measures suc

Design of Two 28 GHz Doherty Power Amplifier Topologies with Vertical In(Ga)As Nanowire Transistors

In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. The DPAs are designed using AWR design environment with virtual source (VS) models of In(Ga)As nanowire transistors and 50 nm gate length. Th

Sexual Orientation, Motherhood and Pay - The case of the gender pay gap for homo-/bisexual women

The aim of this thesis is to widen the understanding of the gender pay gap by introducing the factor of sexuality. Same-sex couples have legal rights that are relatively new; how does our understanding of labor division and pay change when more data on queer people emerge? This is achieved by using data from the German Socio-Economic Panel (SOEP) from the year 2017 and making multiple regressions,

Was that funny? Multi-modal wordplay translation and audience types

In this paper I will set out to show what effect the intended audience of a text has on how one approaches the translation of word play as it appears in comic strips, and how one should analyze those translation. I will do this by analyzing a set of comic strips, all featuring an instance of wordplay which combines the visual and textual elements of the text, which I translated according to metric

Incorporation of unsaturated fatty acids into waterborne UV-curing resins

The project’s main goal was to develop an understanding of how to gain a higher deep cure of UV-curable waterborne polyurethane dispersions for pigmented systems. Specifically, the project studied and concluded that radicals from oxidation of 1.3-4 wt-% of unsaturated fatty acids in the dry film can initiate radical polymerisation of acrylate groups. Polyester polyols containing 0, 5, 10 and 15 wt

BIM i Trafikverket - En kvalitativ undersökning av möjligheter och hinder för implementering

BIM, byggnadsinformationsmodellering, är ett arbetssätt som blir allt vanligare. Det innebär att olika objekt bygger upp en övergripande 3D-modell där man kan finna mängder av information om dessa objekt. Ett objekt kan vara allt ifrån en bropelare till en elstolpe. Syftet med denna rapport är att utifrån Trafikverkets roll som beställare undersöka vilka för- och nackdelar det skulle innebära med BIM, Building Information Modeling, is an increasingly common way of working. This means that different objects build up an overall 3D-model where you can find lots of information about these objects. An object can be anything from a bridge pillar to an electric pole. The purpose of this report is to, based on the Swedish Transport Administrations’ as a client, investigate the advantages and disad

Requirements for Modelling WUI Fire Evacuation by Unconventional Means

Wildfires pose a significant safety issue, especially when they interact with urban areas, known as wildland urban interface (WUI) fires. As wildfire numbers are rising and developments near wildlands are increasing, there is an increased need to model all types of evacuation in order to prepare and inform evacuating authorities and evacuees. There is currently no research on the requirements need

Diet of perch in the Baltic Sea – could the European perch (Perca fluviatilis) be used to combat round goby (Neogobius melanostomus)?

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

Molecular Interactions Between Xanthan Gum, Psyllium, Milk Proteins and Starches, and Their Implications on Gluten-Free Bakery Products

Gluten in bread can cause severe health problems in patients with celiac disease. However, gluten-free substitutions often show impaired quality characteristic like a liquid dough because of a missing gluten-network or accelerated staling due to the high amount of gluten-free starch. Therefore, hydrocolloids are considered to improve gluten-free bread quality characteristics. The idea of this degr

Harbour porpoise (Phocoena phocoena) echolocation activity related to boat noise and boat presence near the Kullaberg marine reserve in northern Öresund, Sweden

The impacts of harbour porpoises by human-made, so called anthropogenic, underwater noise disturbance have been investigated in the past decades. As harbour porpoises are protected under the EU habitat directive, underwater noise management has been proposed as part of conservation efforts. Disturbance of harbour porpoises by ship noise and boat activity has previously been reported to have negati

Utilizing Learnings of Informal Settlements in Community Planning:

Informal settlements, or unplanned sectors of the city, are vital for providing shelter for low and middle income households in the developing world. In the case of Dar Es Salaam, Tanzania, informal settlements have a long history dating back to the early colonial beginnings and today provide housing to over 70% of the city. In these densely populated environments of the informal sector, resident

The role of bone marrow stromal cells in therapy resistance of FLT3-ITD positive acute myeloid leukemia cells

Activating mutations of the FLT3 receptors confers poor prognosis while remaining as one of the most common causes for the survival and propagation of these leukemic blast cells. Years of research into second generation inhibitors proved to be initially effective. However, current studies suggest that microenvironment-mediated signals from bone marrow stromal cells are capable of providing cytopro
