Energi och klimatpåverkan är ständigt aktuellt i dagens samhälle. För att motverka den globala uppvärmningen har EU tagit fram klimatmål där bland annat energianvändningen ska minska med 20 % mot 1990 års nivåer år 2020. En stor andel av energianvändningen orsakas i Sverige idag av bygg- och fastighetsbranschen där byggnadsbeståndet står för ca 30 % av energianvändningen. För att klara EU:s klimEnergy use and climate impact are important topics in today’s society. To combat global warming, the EU has set a goal framework with a 20 % reduction target until 2020 for domestic energy use compared to 1990. Today, the building sector in Sweden accounts for 30 % of the domestic energy use. To achieve the goals for energy and climate set by the EU, changes are required. The Swedish parliament ha

The aim of this thesis was to explore the extent to which wine consumption and drinkers’ perceptions on wine can help understand middle class identity in Shanghai. The research relied on 25 interviews of wine drinkers and non-participant observations, as well as previous studies on middle class identity and consumption in China. The data have been analyzed utilizing Bourdieu’s theories on social d

A major concern of this thesis was the changing meanings of cherry blossoms in Japanese history, and the images of Japan created through the flower. With a peculiar emphasis on today’s international context, when cherry blossoms have become a unique culture of Japan, this research inquired into the process of symbol-making. The Zenith concept of nyoze and poststructural discussions on language-pow

DNA transposons are a class of mobile genetic elements that can autonomously move from one genomic location to another. They are powerful drivers of genetic change and have played a significant role in the evolution of many genomes. One such transposable element, IS608 from Helicobacter pylori employs a unique mechanism of transposition as it transposes in a single-stranded DNA form and inserts sp

In this thesis we use a unique data set to show that there is a cointegrating relationship between the EURO STOXX 50 index and the Markit iTraxx Europe index that can be exploited through trading. As far as we know, we are the first ones to write about trading this pair in an academic paper. On our way we deal with various peculiarities in the data set before we manage to find cointegration. The c

Torka är mycket vanligt i Botswana. I huvudstaden Gaborone har Gaboronedammen klassats som ett misslyckande eftersom vattennivån har sjunkit till under sex procent av den potentiella volymen under 2014. Det finns inte någon officiell enighet om vad som har orsakat denna extrema volymminskning. Vattenbrist kan ha negativa konsekvenser för ett lands ekonomi, utveckling och till och med för den natioBotswana is an arid country endemic to drought. The major water supply in the capital Gaborone, the Gaborone Reservoir, has received a failed status early this year due to diminishing water levels which have fallen below six percent of the total potential volume in 2014. However, there seems to be no official consensus as to what has caused this extreme decrease in volume. Water scarcity can have

Carbonatite is an unusual type of rock that, for a long time, were not accepted for what they really are. This group of rocks is now considered to be of igneous origin and is classified after its content of carbonate minerals. If it exceed 50% the rock will be named a carbonatite. This group of rocks can be found all over the world and two of these places, which this review will focus on, are the

The aim of this study was to examine how social problems are described and constructed in the printed press from two different regions in the south of Sweden; the rural municipality of Svalöv and the densely populated city Malmö. The study was based on news articles from the printed newspaper with the biggest daily circulation, from the respective areas. Articles relating to a predetermined array

The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values

Organismer i våra sjöar och hav måste ständigt kämpa för sin överlevnad i en miljö fylld av olika stressande faktorer, inte minst till följd av mänsklig påverkan. I en laboratoriestudie har jag undersökt hur den vanliga sötvattensfisken ruda (Carassius carassius) störs av två olika faktorer som misstänks påverka fiskars välmående – exponering för en anti-depressiv medicin (fluoxetin) och risken föOrganisms in the aquatic environment face the challenge of exposure to environmental pollution by a multitude of pharmaceuticals. However, the potential for disruptive effects in non-target aquatic organism remains poorly understood. Fluoxetine is one of the most commonly prescribed psychoactive drugs and it has been shown to bioaccumulate in fish, and potentially affects a broad suite of importan

Title: Open-source Branding: How consumers develop a Corporate Brand Image through Instagram- An Exploratory Single-Case Study. Research problem: The research problem originates from the shifted power balance through the rise of social media. Whereby, organizational control of the brand image is starting to fade. Thus, further research is needed, whether an open-source branding strategy truly aff

Dödliga gasen kolmonoxid – behandling mot prostatacancer? Kolmonoxid är för de flesta människor känd som en gas som kan orsaka förgiftning och snabbt leda till döden. Små doser av kolmonoxid har dock upptäckts kunna motverka inflammation. Många forskare är övertygade om att kolmonoxid inom en snar framtid skulle kunna användas som läkemedel mot bland annat kronisk tarminflammation. Ett hopp har oAcute or chronic inflammation in the prostate is implicated in pathogenesis of benign prostate hyperplasia (BPH) as well as development of prostatic intraepithelial neoplasia (PIN) and prostate cancer (PCa). Chronic prostatitis (inflammation in the prostate) is associated with high morbidity and negatively impacts life quality. Macrophages are critical regulators of inflammatory processes and are

Nowadays, the CORDIC algorithm plays an important role to deal with the non-linear functions in hardware. In this thesis, a novel methodology is described to reduce the complexity in an unrolled CORDIC architecture, which gives higher speed, lesser area, and lower power consumption. That is, MUXes are used to replace adder stages. Five different unrolled CORDIC architectures have been implemented

Fastighetsbildningslagen (FBL) antogs 1970 och ersatte ett tiotal lagar gällande fastighetsbildningsåtgärder. Bestämmelserna kom nu att samlas och bli mer översiktliga. Ett nytt fastighetsbildningsinstitut som instiftades var fastighetsreglering. Detta institut skulle ersätta ägoutbytena som fanns i den äldre lagstiftningen. Tanken med ägoutbyte var att kunna utföra ömsesidiga byten av relativt smThe Swedish real estate law was adopted in 1970 and replacing the many existing laws regarding real estate measures. This lead to a better overview. A new real estate institute was about to take shape, which was to replace the old institute of change of land areas. The new institute, property reformation institute, was to be similar to the old one with the aim of exchanging small areas of land bet

Based on qualitative interviews with schoolteachers and school principals the present thesis studies the experience as well as sensemaking process of the principals and the teachers during the implement

The effect of physical exercise on inflammatory cells of the brain Neurodegenerative diseases are the leading causes of permanent cognitive impairment and motor dysfunctions in the adult population worldwide. These diseases are characterized by neuroinflammation (inflammation in the brain), primarily mediated by resident immune cells of the central nervous system known as microglia. As pharmaceut

This thesis is about the global trend of the profiling of nursing homes, with specific focus on two empirical cases of profiled nursing homes in Sweden and Denmark. The profiled nursing homes, and their social dynamics, are analyzed on the basis of data collected through ethnographic fieldwork and additional documentation. The profiled nursing homes are institutional attempts to satisfy what are b

Using the 3D finite element tool COMSOL a III-V FinFET was mod- eled based on Cezar Zota, Erik Lind and Lars-Erik Wernerssons work. Using this model, the gate-source parasitic capacitance, the gate-drain parasitic capacitance, the source and drain resistances were simulated. Changing the geometry of the FinFET was done in order to optimize the transistor in regard for the transition frequency and
