We still have limited knowledge about the underlying genetic mechanisms that enable migrating species of birds to navigate the globe. Here we make an attempt to get insight into the genetic architecture controlling this complex innate behaviour. We contrast the gene expression profiles of two closely related songbird subspecies with divergent migratory phenotypes. In addition to comparing differen
Two probiotic products containing either live Lactobacillus plantarum strain DSM 15313 or bilberries fermented by the same bacterial strain were tested for their antihypertensive potentials and their impact on the oral and the faecal microbiota in hypertensive adults. The results showed that consumption of the tested products for three months did not reduce the blood pressure in adults with hypert
The aim and purpose of this thesis is to evaluate the utilization of private-public collaboration of the exchange of information on risks and vulnerabilities concerning food supply in Sweden, with a view to provide the participants with recommendations on how to improve or how to initiate this collaboration. The study consists of interviews with respondents from Swedish municipalities, one Swedish
Att uppskatta lövyteindex med satellitdata Vegetation har unika spektrala egenskaper som kan användas inom fjärranalys för att få information om viktiga ekologiska parametrar, som t.ex löyteindex (eng. leaf area index, LAI, lövyta per markenhet). LAI styr många ekologiska processer som fotosyntes och transpiration. Med hjälp av satellitbilder kan man uppskatta LAI i stor skala. Vegetation absorLeaf area index, LAI, is an important biophysical parameter in ecological modeling. It is the ratio of leaf area per unit ground area. To obtain LAI over large areas in a fast and convenient way the use of satellite data is important. Aim of the project was to determine if there is a relationship between LAI and red-, NIR reflectance and a couple of vegetation indices: Global Environment Monitorin
Svensk populärvetenskaplig sammanfattning Fjärranalys av skogsskövling längs med den trans-amzoniska motorvägen Skogsskövling är ett av de större miljöproblemen vi har idag. Speciellt snabb har skövlingen varit i Amazonas regnskog, där minst tjugo procent försvunnit de senaste 40 åren. Fjärranalys används för att uppskatta skogsskövling längs med den transamazoniska motorvägen (BR230). Analysen utDeforestation is one of the biggest environmental challenges today. Especially severe has the deforestation of the Amazon rainforest been where at least 20% has been cleared the last 40 years. A time series analysis of deforestation rates between 1984 and 2013 has been performed on several sites close to the Trans-Amazonian highway BR230 in the Amazon and Para states. This is done by applying a su
Vår undersökning har följt den svenske rapartisten Einár genom hans karriär. Vi har observerat olika händelser som han har uppmärksammats för, som att han har vunnit pris, att han har blivit kidnappad och rånad, och att han slutligen har blivit skjuten och avled till följd av en skottlossning. Källorna som används är diverse artiklar från SVT Nyheter (som finansieras av public service). I vår anal
Majoriteten av världens extremt fattiga bor i rurala områden och 300 miljoner av dem i Indien och Kina. Trots att länderna kommit en bit på vägen i sin strukturella omvandling arbetar fortfarande runt hälften av befolkningen på landsbygden inom jordbruket. De direkta och indirekta effekterna som den primära sektorn skapar har visat sig viktiga av olika anledningar. Hur detta kommer sig undersöks n
Focal non-convulsive status epilepticus (fNCSE) is a neurological condition characterized by a prolonged seizure that may lead to the development of epilepsy. Emerging experimental evidence implicates neuronal death, microglial activation and alterations in the excitatory and inhibitory synaptic balance as key features in the pathophysiology following fNCSE. We have previously reported alterations
Exposure to air pollution is associated with adverse health effects in humans, with special concern for exposure to fine particulate matter (PM2.5). The physicochemical properties of aerosols impact the health effects. Considering that we spend approximately 90% of our time indoors, it is important to gain increased understanding of indoor aerosol concentrations and properties. The overall aim of
Uppsatsen behandlar vilka förändringar som uppkommer på spread (vilket är skillnaden mellan köpkurs och säljkurs) på handelsvolym och på volatilitet när ett företag genomför återköp av egna aktier. Vi undersöker vad dessa förändringar får för innebörd för investerarna och förtagen. Med bakgrund i amerikanska forskningar analyserar vi 35 stycken företag i Sverige som har genomfört återköp en eller
I denna uppsats undersöks hur musikkreatörer upplever de förändringar som skett i musikbranschen de senaste tio åren till följd av den tekniska utvecklingen i form av bland annat gratisteknologier och tjänster som Spotify samt fildelning. I undersökningen har kvalitativa metoder i form av intervjuer använts. Vi har utgått från ett antal teoretiska begrepp som exempelvis medielogik, mediekonvergens

Research SummaryGrowth often requires start‐ups to recruit new skills not present in the founding team. We analyze if the relationship between integrating new skills and growth depends on timing. Should new skills be recruited as early as possible, or can start‐ups add them as needed along the way? Using a unique panel dataset covering Sweden's population of start‐ups from 1997 to 2012, our analys
The focus and instruments of innovation policy have changed fundamentally over the last decades. Recently transformative innovative policy has caught the attention of scholars and policy makers, arguing that this is a new shift in the policy discourse. Even though grand challenges such as global warming and migration flows, as well as technological change such as artificial intelligence and indust
In this chapter, we study the relationship between regional economic resilience and agency. Especially since the 2008 recession, regional resilience has raised a lot of interest in economic geography. However, the resilience research has focused mostly on the structural perspective and the role of agency has gained less attention. Intentional and purposeful human actions can have an effect on regi
In this article, we demonstrate a method for inducing reversible crystal-to-crystal transitions in binary mixtures of soft colloidal particles. Through a controlled decrease of salinity and increasingly dominating electrostatic interactions, a single sample is shown to reversibly organize into entropic crystals, electrostatic attraction-dominated crystals, or aggregated gels, which we quantify usi
Worldwide significant efforts are ongoing to develop devices that store solar energy as fuels. In one such approach, solar energy is absorbed by semiconductors and utilized directly by catalysts at their surfaces to split water into H2 and O2. To protect the semiconductors in these photo-electrochemical cells (PEC) from corrosion, frequently thin TiO2 interlayers are applied. Employing a well-perf
Regional growth models leave a large share of variation unexplained. While we should continuously aim to improve these models, the unique combination of conditions and human agency in each region will also invariably lead to region-specific growth trajectories. Theoretically, we should thus expect systematic deviations from growth predictions. We propose an approach to explore these unexplained de
Cars are nowadays being programmed to learn how to drive themselves. While autonomous cars are often portrayed as the next step in the auto-motive industry, they have already begun roaming the streets in some US cities. Building on a growing body of critical scholarship on the development of autonomous cars, we explore what machine learning is in open environments like cities by juxtaposing this t
