The main purpose of this thesis is to increase the understanding of how hydrogeological conditions are affecting the local water resources in Carrizal on the Barva Volcano, Costa Rica. Hydrogeological investigations of spring characteristics, soil infiltration rates and water flow in springs and rivers were conducted at the study area in Costa Rica as part of a Minor Field Study (MFS). A statistic

The goal of the thesis is to create a method that can be used to smooth data functions so that they are more easily readable and interpretable, through curve fitting. So as to do that, we adapt the smoothing spline method, which uses discrete data, to continuous data.

Mass Spectrometry- based proteomics has matured to an analytical tool applicable in many areas of life science. Although, limitations remains where much focus has been towards the development of search engines to more accurately identify peptides in fragmentation spectra. This report aims to investigate four search engines; MSGF+, Andromeda, MSFragger and pFind in order to assess the advantages an

Fibrosis is a process characterized by the accumulation of extracellular matrix components and is attributed to excessive scar formation and is a common feature of many chronic inflammatory conditions. Fibrogenesis involves multiple inflammatory cells including NKT cells, which have been suggested to play a prominent role in the control of this process. Here we characterize a transgenic mouse mode

Plant-insect interactions play a crucial role in the evolution of the coevolving web of life, shaping local interaction networks and moulding the diversity and the evolutionary history of two of the most diverse groups of organisms on earth. The interaction between Lithophragma bolanderi (Saxifragaceae), which presents a geographic mosaic of ploidy levels, and the pollinating floral parasite Greya

This study compares the performance of equal- and value-weighted portfolios using a broad investment universe consisting of the stocks from the Swedish stock market. While implementing random sampling in the portfolio construction procedure, three rebalancing schemes are applied on the equally weighted portfolio in order to observe differences in performance among these. In order to compare how mu

Attosecond pulses obtained via high harmonic generation often suffer from chromatic aberration. This is inherent from the generation process as a consequence of the spatial profile of the driving laser pulses. Consequently, the focus positions and divergences of consecutive harmonics vary, leading to chromatic aberration which prevents high-quality refocusing as is critically required for applicat

Several findings show that dark matter makes up 27% of the universe. The goals of this thesis are to understand some of the most important evidences and candidates for dark matter, as well as how dark matter is searched for. The ATLAS and LDMX experiments are reviewed to give a greater insight into the search for dark matter. Two papers from ATLAS are studied more carefully and the data from these

It is known that consumption of high fat diet may lead to gut dysbiosis and increase intestinal permeability by altering gut microbiota composition. However, metabolites from dietary fiber fermentation, short chain fatty acids (SCFAs) may prevent these changes. SCFAs are of great importance in maintaining colonic integrity, and exerting anti-inflammatory function as signaling molecules. The presen

Inclusive innovation is seen as a means to counteract the issue of growing global inequality. Particularly universities and private businesses are engaged with its promotion. However, the concept of inclusive innovation has deficiencies concerning the operationalisation and measurement. In default of extensive primary data, a set of a hundred and two inclusive innovations has been gathered from tw

This study analyzes the relationship between education, antibiotic consumption and antibiotic resistance in the European ambulatory care. For this purpose, a panel data analysis is conducted on an aggregate level in a sample of 30 countries in the European Economic Area between 2000 and 2014. The main variable of interest is the level of high education, expressed as the proportion of the total pop

Wireless communication nowadays is playing a vital role in real-life data transmission. This communication can be machine-to-machine or human to machine communication. In each of these categories, reliability and low latency data transmission are critical factors of success transmission in case the number of devices in a certain area increases. In this thesis, I mainly investigate on smart manufac

Traditionally Bhutanese buildings are built with rammed earth. These buildings have low insulation values and lack thermal comfort resulting in sub-zero temperatures inside the homes in colder regions. Modern insulation materials in Bhutan are uncommon due to the lacking availability, and therefore, a local source of insulation material is needed to improve the living conditions. The worldwide use

In Reinforcement learning the updating of the value functions determines the information spreading across the state/state-action space which condenses the valuebased control policy. It is important to have an information propagation across the value domain in a manner that is effective. Two common ways to update the value function is Monte-Carlo updating and temporal difference updating. They are

This study aims to explore the impact of paid work in the Ethiopian export-oriented garment industry on women’s empowerment, as perceived by the women themselves. The study first explores the reasons for why and how women pursue paid work in the industry. It further examines the ways in which paid work might affect women’s intra-household decision-making. By focusing on the experiences among vario

The present thesis is an investigation about the analysis and study of what is the best way to obtain greater savings of heat principally from the reuse of Drain Hot Water (DWH). The study is carried out through the hypothetical application of one of these heat reuse systems and the installation of renewable solar system to reduce the electricity consume in a single-family house of 300 m2 located

I den här studien utforskas hur makt uttrycks genom språket i den Sydkoreanska filmen Parasit. Likt andra populärkulturella fenomen producerar och reproducerar Parasit en bild av ett samhälle. I samband med det speglas interaktioner mellan individer och uttryck för hur deras relationer skapas. För att få en god förståelse för språkanvändningen i filmen Parasit görs en kvalitativ innehållsanalys av

From astrophysical and cosmological observations, it is known that most of the matter in the Universe is dark. This matter could be explainable by new particles, not included in the Standard Model of Particle Physics. This work assumes that there exists an interaction between dark matter and Standard Model particles, and investigates if the present relic density of dark matter in the Universe coul

Med hjälp av netnografisk metod undersöker jag fenomenet tematiska köp-och säljgrupper på Facebook. Tematiska köp-och säljgrupper kan förklaras som nätverk bestående av medlemmar som dels köper, byter och säljer varor med varandra och dels interagerar kring ett gemensamt intresse för vissa varor och märken. Studien tar avstamp i den svenska köp-och säljgruppen Labels we love (svenskt/danskt/snyggt
