The major histocompatibility complex (MHC) is a membrane protein group of central importance in the immune system. It is divided into two main classes, class I and class II. The MHCs are highly polymorphic which is believed to be indication of trans-species polymorphism (TSP). There is TSP when an allele is maintained in two species through a speciation event. The songbirds that I study here belon

Antalet människor i världen med tillgång till elektroniska produkter som datorer och smartphones ökar kraftigt. I takt med att antalet produkter går upp så ökar även deras prestanda. Men är det bara att fortsätta bygga mindre och bättre komponenter för alltid? I den här artikeln beskrivs ett bekymmer som uppstår då elektroniska komponenter blir mindre, och några resultat från ett arbete som utförtWith the constant downscaling of transistors, silicon as a production material is falling out of favour because of increasing power consumption when the size of devices becomes smaller. Compound materials from group III-V in the table of elements are promising candidates to replace silicon. The aim of this work was to study current-voltage characteristics of a MOS capacitor made of the III-V compo

This paper investigates the impact of political risk on financial performance. In order to assess the quantitative measure of political risk principal component analysis is performed referring to six indicators, which measure different areas of political environment. We employ several macroeconomic factors as control variables to strenghten the explanatory power of estimation. Panel data methods a

Studiens syfte var att undersöka konstituering av mening kring äldredepression bland självidentifierade äldre och primärvårdsläkare i Sverige.

Avoiding consumer skepticism of corporate social responsibility programs has become an important factor in CSR communication. Literature points towards a need for a more consumer-focused, symmetrical approach to CSR communication, especially in the case of cause-related marketing. The Estee Lauder 2014 Breast Cancer Awareness Campaign uses a co-creational approach to CSR, centered on user-generate

In this work we aim to develop a video-based face verification algorithm suitable for real-time use in an embedded environment with limited space and restricted computational resources. We investigate face verification based solutions to envisioned real-time video applications that require open-set face identification. In particular, we create a prototype system for keeping track of the identities

För att nå fram med budskap i dagens allt mer stegrande informationsbrus, krävs metoder som får mottagarna att reagera och lägga märke till det som sänds ut. En av dessa metoder är så kallad “dold PR”, där det verkliga budskapet är dolt bakom en annan nyhet, eller helt enkelt utger sig för att vara något annat än vad det är. Denna studie undersöker fenomenet ”dold PR” ur ett mottagarperspektiv, däTo get across messages in todays ever more increasing information noise requires methods that get recipients to react and take notice of the message.
