Patterns of local adaptation are expected to emerge when selection is spatially heterogeneous and sufficiently strong relative to the action of other evolutionary forces. The observation of local adaptation thus provides important insight into evolutionary processes and the adaptive divergence between populations. The seaweed fly Coelopa frigida exhibits an inversion polymorphism in all population

Om du tar dina två händer, så ser du att de är spegelbilder. Däremot är din vänsterhand inte identisk med din högerhand. De går inte att placera på varandra, utan måste läggas handflata mot handflata för att passa ihop. Detta kallas kiralitet. Kroppen är enda ner på molekylnivå kiral, det vill säga även de minsta byggstenarna i cellerna är kirala. När ett läkemedel designas vill man att det ska paWe have investigated the synthesis of anti-β-Hydroxy-α-amino Esters from the corresponding β-Keto-α-amino Esters. The coupling of Asymmetric Transfer Hydrogenation (ATH) with Dynamic Kinetic Resolution (DKR) allows us to control the relative and absolute stereochemistry of the product. The procedure uses a 1:2 mixture of formic acid and triethylamine as hydrogen source, and (S,S)-[RuDPAE(mesitylen

The purpose of my thesis is to examine if the financial crisis 2008-2009 effects economic gender equality in Sweden during (2008-2009) and after (2010-2015) the crisis and if so, how. The purpose is also to analyse if the outcomes are consistent with Gary S. Becker´s theoretical framework the taste discrimination model and the division of labour model. I define economic gender equality by using th

Syftet med denna masteruppsats är att undersöka människors upplevelser av att delta i flyktingmottagandet i Malmö under hösten 2015. Uppsatsen studerar motiveringar till varför volontärer beslutat sig för att hjälpa. Dessa analyseras främst genom Marcel Mauss teori om gåvosystem: volontärarbete, eller att hjälpa, ses som en gåva i uppsatsen. Motiveringarna analyseras också genom Erving Goffmans drThe purpose of this master’s thesis is to explore the experience of people who helped in the refugee reception in the city of Malmö, Sweden, in the fall of 2015. The thesis delves into the reasons and motivations to why volunteers decided to help. These are primarily analysed through Marcel Mauss’ gift-exchange theory where volunteering is seen as a gift; and secondarily by Erving Goffman’s dramat

Syftet med detta arbete är att kartlägga hur reglerna för ledningsrätt för basstationer ser ut och hur de tillämpas i praktiken. Arbetet avser att besvara hur många ledningsrätter som bildats efter ändringen av ledningsrättslagen (1973:1144) år 2004, vilken utökade möjligheterna att upplåta ledningsrätt för basstationer. Vidare avser arbetet besvara hur dessa upplåtelser utformats, varför man som A utility easement right includes the right for the telecommunication operator to permanently use a private property for its purpose, without an agreement with the property owner, for a relatively low compensation fee. The Swedish utility easements act was expanded in 2004, to cover not only ordinary land cables but also wireless base stations. The intent of the law change was to facilitate the co

Centerpartiet har under senare år flera gånger marknadsfört sig som “Alliansens gröna parti” och försökt profilerat sig som ett liberalt alternativ till andra gröna krafter. I vår analys utgår vi ifrån centerpartiets valmanifest och program mellan 1917-2014 för att analysera dessa utifrån Koselleck och Skinners teorier. Vi har valt att tolka metoderna för att passa till vårt studieobjekt och sedan

Microchannel acoustophoresis is a technique which uses acoustically induced forces to translate particles in a microchannel. Its use in biological applications is increasing. Using acoustophoresis to precisely manipulate bioparticles such as yeast, blood cells and cancer cells gives the technique great potential. However, manipulation of sub-micron particles such as bacteria, platelets and micro-v

Asylärendena kännetecknas av vissa unika särdrag. Till dessa kan räknas den enskildes ofta prekära situation, och att beslutsfattaren ska ta ställning till huruvida den sökande befinner sig i en situation i vilken denne är berättigad internationellt skydd undan förföljelser eller inte. Även maktförhållandet parterna emellan stärker behovet av försiktighet från beslutsfattarens sida. För att hanterThe asylum process is characterised by certain unique features. Amongst these are the precarious situation of the applicant, and the fact that the decision maker is to decide whether or not the applicant is in a situation that entitles him or her to international protection. The balance of power between the two parties is also a key feature that strengthens the need of caution by the decision make

Jet and hydrocarbon fires are severe fires with the potential of creating large scale events which leads to serious accidents with both casualties and injuries. In this study, practical jet and hydrocarbon fire tests were carried out to assess standard ISO 834 based protection as well as improved passive fire protection. The tests showed that the ISO 834 protection is not sufficient. This standard

Ekonomistyrning i tjänsteföretag har under senaste åren varit ett väl debatterat ämne, uppmärksamheten har ökat alltmer med dess märkbara betydelse för ekonomin. Syftet med rapporten var att undersöka i vilket utsträckning ekonomistyrning tillämpas i små It-företag.

Syftet med uppsatsen är att undersöka hur finansiella instrument, med fokus på preferensaktier och obligationer, påverkar kapitalkostnaden i fastighetsbolag och hur dessa bolag motiverar sina finansiella strategier. Därtill undersöks den finansiella risken förknippad med kapitalstrukturen som beror på dessa instrument och hävstången i bolaget. Motiven till finansieringsstrategierna undersöks även The aim with this thesis is to evaluate how financial instruments, mainly preferred shares and bonds, affect the cost of capital in publicly traded real estate companies. We also want to investigate how the companies motivate their financial strategies of choice. With knowledge of the capital structures we make connections to the development of financial risk in the companies related to the financ

This thesis explored the path following applications of autonomous driving, where the purpose is to sense the environment and navigate to a goal without human intervention. Autonomous driving enables safer journeys by removing human error in driving, as well as reducing fuel consumption and driving time by optimizing the engine and brake actuation. In 2017 it is a well researched topic in the acad

Economic impacts of drought events can amass to billions of Euros within the EU. Ways to estimate the amount of water in the soil is thus very valuable to gather information which could be used for decision making. This thesis looks at different ways to estimate the amount of water in the soil, the so called soil moisture. The E-HYPE model from the Swedish Meteorological and Hydrological Institute

Untreated asthma limits the ability to live an active life, still many asthmatics does not have the level of control over their asthma as they could have. In addition, about 50% of the asthmatics use their inhaler incorrectly, which affects the result of the medicine negative. The asthma inhaler is central in an asthmatics living and has great potential for de- velopment towards a modern asthma mo

Throughout the developing world the informal (“black”) economy is a current issue. It constitutes a source of vulnerability to the people affiliated to it, and further hampers the nation´s economic performance. In addition it is at large unresponsive to policy change, and is further on difficult to monitor by government officials. The informal economy is a global problem. Previous studies on the i

The spread of pathogens between individuals has important effects on patterns of mortality, behaviour and the genetic structure of populations. One factor that is predicted to influence the transmission of pathogens is the genetic diversity of the host group. Groups of closely related individuals are susceptible to similar pathogens, and hence increase in genetic diversity of the group should decr

Människor spenderar mycket tid inomhus, närmre 90 % av sin livstid. För att erhålla ett bra inneklimat med god luftkvalité krävs att byggnader ventileras. Därför utrustas de ofta med mekaniska ventilationssystem. Trots detta är SBS (Sick Building Syndrome) ett allvarligt problem. Orsaken till att vissa byggnader blir ”sjuka” tros bero på bland annat dålig ventilation. För att avgöra om ett ventilaPeople spend a lot of time indoors, closer to 90% of their lifetime. To obtain a good indoor climate with good air quality buildings need to be ventilated. Therefore, they are often equipped with mechanical ventilation systems. Nevertheless, SBS (Sick Building Syndrome) is a serious problem. The reason that some buildings become "sick" is believed to be due to, among other things, poor v

I Sverige bedrivs en omfattande transport av farligt gods på vägnätet, vilket medför allvarliga risker för samhället (Stenberg, 2007). För att hantera riskerna från transporten föreslås riskreducerande åtgärder, vars effekter dock är osäkra (Sanglén, 2005). Mot bakgrund av det begränsade beslutsunderlaget vid fysisk planering av riskreducerande åtgärder för transport av farligt gods motiveras därf
