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
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

Syftet med detta arbete är att undersöka diskussionen kring testamentsregister i Sverige. Den deskriptiva delen av arbetet inriktar sig främst på varför Sverige saknar ett nationellt testamentsregister och vilka argument som har framförts för och emot ett sådant. För att ytterligare belysa frågan behandlas rättsläget för testamentsregister i Danmark och Norge som båda har någon form av testamentsrThe aim of this thesis is to discuss if registration of wills in Sweden would be possible. The descriptive part focuses mainly on why Sweden does not have a national register of wills and the arguments put forward for and against such a register. To further highlight the issue the register of wills in Denmark and Norway will be dealt with. Both of these countries have different forms of testamenta
BACKGROUND: Surveys are a common way to measure annoyance due to road traffic noise, but the method has some draw-backs. Survey context, question wording and answer alternatives could affect participation and answers and could have implications when comparing studies and/or performing pooled analyses. The aim of this study was to investigate the difference in annoyance reporting due to road traffi
Popular Abstract in Swedish Vid en knäprotesoperation ersätts ledytorna i knäet med en protes gjord av metall och plast. Den vanligaste orsaken till denna operation är artros(ledsvikt. Antalet knäprotesoperationer ökar stadigt och 2009 utfördes 12,700 förstagångsoperationer i Sverige. Resultaten är överlag goda men en allvarlig komplikation som drabbar mellan 1 och 2% av patienterna är bakterieinfThe Swedish Knee Arthroplasty Register (SKAR) was used to identify 478 cases that underwent a first-time revision with exchange or removal of the prosthesis due to infection during the years 1986–2000. 30% of the infections were diagnosed within 3 months from primary operation and two-thirds were diagnosed within 2 years. These cases frequently had a history of wound complication after the primar
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
A comparison between three different types of particle sizing instruments (fast mobility particle sizer, FMPS; electrical low pressure impactor, ELPI; and scanning mobility particle sizer, SMPS) and one condensation particle counter (CPC) was made to compare instrument response in terms of size distributions and number concentration. Spherical oil droplets in 39 different sizes, with geometric mea
Experimental aerosol generation methods aim to represent natural processes; however, the complexity is not always captured and unforeseen variability may be introduced into the data. The current practices for natural and experimental aerosol generation techniques are reviewed here. Recommendations for best practice are presented, and include characterization of starting material and spray fluid, r
Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. Combustion can also generate brown carbon (BrC) particles, with absorpti
Looking at globular proteins with the eyes of a colloid scientist has a long tradition, in fact a significant part of the early colloid literature was focused on protein solutions. However, it has also been recognized that proteins are much more complex than the typical hard sphere-like synthetic model colloids. Proteins are not perfect spheres, their interaction potentials are in general not isot
Simple models based on isotropic interparticle attractions often fail to capture experimentally observed structures of colloidal gels formed through spinodal decomposition and subsequent arrest: the resulting gels are typically denser and less branched than their experimental counterparts. Here, we simulate gels formed from soft particles with directional attractions ("patchy particles"), designed
A simple Pickering emulsion route has been developed for the assembly of temperature-responsive poly(N-isopropylacrylamide) (PNIPAM) microgel particles into colloidal molecules comprising a small number of discrete microgel interaction sites on a central oil emulsion droplet. Here, the surface activity of the microgels serves to drive their assembly through adsorption to growing polydimethylsiloxa
Passive integrated transponder (PIT)-tagging is commonly used in behavioural studies of fish, although long-term evaluations of effects from tagging under natural conditions are scarce. We PIT-tagged common bream Abramis brama, European perch Perca fluviatilis, pike Esox lucius and roach Rutilus rutilus, released them in their lakes of origin and recaptured them after 103–3269 days. Overall, tagge
Introduction Given that in developed countries we spend about 65% of our time in private homes (Brasche et al. 2005), understanding the exposures in homes is of outmost importance. Airborne particle concentrations indoors can be affected by particles of indoor and outdoor origins, as well as physico-chemical processes indoors, outdoor infiltration affected by tightness of the building envelope and
