Det finns många komplexa sjukdomar som i dagsläget är mycket svåra att diagnostisera. Det är inte ovanligt att när dessa sjukdomar slutligen diagnostiseras så är det för sent för att kunna göra någonting åt det. Men med en ny teknik kan det bli möjligt att ställa diagnoser i tid. Tekniken grundar sig i att, från ett vanligt blodprov, identifiera vilka proteiner som finns i blodet varpå sedan låta When using antibody microarrays to diagnose diseases, the process of quality control of the microarray data is an important step. Currently, a part of this process is performed manually by visual inspection. In this master project, we aim to automate the quality control in order to make it reproducible, as well as to find out which properties of the data that have the most to do with its quality.

I den statliga utredningen, Ett snabbare bostadsbyggande, undersöktes hur utnyttjandet av byggrätter kunde effektiviseras. Underlaget var dock tämligen begränsat, vilket skapade idén till den här rapporten. I vilken utsträckning förekommer outnyttjade byggrätter och varför utnyttjas de isåfall inte? Syftet med denna rapport är att utreda om det finns outnyttjade byggrätter med ändamål flerbostadsIn the public report, Ett snabbare bostadsbyggande, a research was made to find out how the utilization of undeveloped building rights could be made more efficient. However, the material on which the research was based was found insufficient, which created the idea for this report. To what extent do undeveloped building rights occur and what are the reasons? The purpose of this report is to exami

The purpose of this essay is to understand the way yoga is practiced in Sweden through postcolonial feminist theory. The ambivalence of the form yoga takes in a swedish context between the positive aspects it provides for many practitioners in relation to the colonial history and the commodification of the practice is examined through the theoretical and political debate regarding the word cultura

This paper aims to investigate the development of social trust over time globally, as well as separately for continents and countries. This is done by using data from six different surveys and through an interpolation method making the survey measures comparable, resulting in a long and continuous data set. Consequently, with Gini measures from the new Standardized World Income Inequality Database

A sample of 107 asset sales completed globally from October 2006 to January 2019 has been investigated to find the average discount at which the assets of distressed energy companies are liquidated. In the next step, the difference in difference approach has been used to explore the oil price crash in the fourth quarter of 2014 so as to find the difference in the average discount on the assets of

Ända sedan 1781, när William Herschel upptäckte Uranus, så har astronomer letat efter planeter som ligger ännu längre ut. Solsystemet är ett stort ställe, så om man vill hitta någonting så krävs lite vägledning till var man ska leta. 2016 publicerade astronomerna Konstantin Batygin och Mike Brown en studie om små objekt utanför Neptunus, där de hade upptäckt att många av de här himlakropparnas banClustering of orbital characteristics for distant Solar System objects has been proposed to indicate the presence of a ninth planet. Simulations show that the planets orbit would have to have a mass of 5–10 Solar masses, a semi-major axis of 400–800 AU, an eccentricity of 0.2–0.5 and an inclination of 15–25°. Simulations of a planet scattering off a giant planet into a highly eccentric orbit, show

Elektroner, fast de inte kan ses med blotta ögat, har en grundläggande betydelse i vår vardag. Inom vår natur finns många exempel på system av elektroner som interagerar med varandra, så kallade flerelektronsystem: från materialet i elektronikkomponenter ner till några av de minsta beståndsdelarna i vår natur, atomer. Vi har utvecklat en Greenfunktion-teori för att beskriva material och flerelektrAn ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. The formalism is applied to four model systems within GWA: a three-

LED identifies with local resource mobilization, allocation and use. As governments adopt the Private sector led development strategy, Public Private Pa

The purpose of this study is to further deepen the knowledge surrounding credit rating announcements and their impact on companies’ stock prices. Furthermore, the authors want to investigate whether the potential impacts differ between the US market and the European market, as well as previous to the financial crisis compared to post the financial crisis of 2007- 2009. The methodology used is an e

I dagens samhälle är ett hållbart alternativ till fossiltbränsle högt efterfrågat. Biobränsle är ett alternativ, men om detta alternativ ska vara optimalt, måste det härstamma från ett billigt och lättillgängligt material, som t.ex. cellulosa. Cellulosa finns i bl.a. växtcellväggar och är uppbyggd av sockerenheter (glykos) i en väldigt stabil struktur vilket är en bra egenskap när den sitter i växIn this thesis the enzyme Lytic polysaccharide monooxygenase (LPMO) is investigated. The LPMOs have captured the interest of the biofuel industry due to their ability to boost the breakdown of cellulose. Researchers have progressed in mapping out the mechanism behind this oxidative reaction. However, there are still many uncertainties concerning the intermediates involved and the role of certain a
