The fact that solitary migratory birds can find their migration routes has indicated the possibility that a genetic basis may be involved in determining the route of migration. Researchers have also found evidence to investigate this hypothesis in various ways. The focal species of this study is the willow warbler (Phylloscopus trochilus), which has three described subspecies (trochilus, acredula

This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a

The product price given when producing offshore is not the entire truth and more companies decide to move their offshore production nearshore (Stentoft et. al, 2016). To measure the actual cost of producing many more parameters than visible costs needs to be taken account for. There are advantages as well as risks with outsourcing and costs can increase with distance such as quality issues, freigh

Vår hud är hem för en stor grupp av mikroorganismer, hudens mikroflora, som påverkar vår hälsa och vårt välbefinnande. Ändå finns det många aspekter av detta ämne som ännu är outforskade. Detta projekt syftade till att optimera en metod för analys av hudens mikroflora och effekten av hudvårdsprodukter på hudens mikroflora, från provtagning och provberedning till analys med kvantitativ polymeraskedOur skin is home to a vast community of microorganisms, the skin micro flora, which affect our health and well-being. Yet, there are many aspects of this topic that are still unexplored. This project aimed to optimize a method for analysis of the skin micro flora and the effect of skin care products on the skin micro flora, from sampling and sample preparation to analysis with quantitative polymer

Alla påverkas av cancer, direkt eller indirekt och under de senaste decennierna har antalet cancerfall ökat. Med strålbehandling kan man bekämpa cancern genom att bestråla tumören med joniserande strålning samtidigt som man försöker skydda omkringliggande frisk vävnad i den mån det går. Med dagens teknik kan man uppnå bättre tumörkontroll samtidigt som den friska vävnaden kan skyddas i större utrsBackground/Purpose: The aperture shape controller (ASC) was introduced in the Eclipse treatment planning system to reduce plan complexity by counteracting irregular multileaf collimator (MLC) shapes. This should lead to decreased difference between the planned and measured dose distribution. The ASC was investigated to examine if it could limit plan complexity so that the planned and measured dose

As the world is changing rapidly in many ways, competition is getting increasingly fierce amongst manufacturing firms. As such, it has become more and more important for companies to properly understand the needs of their customers in order to provide enough value to be sufficiently competitive. Providing delivery and installation services which might’ve been viewed as necessary evils before have

Idag byggs det oerhört mycket. Nyproducerade bostäder konstrueras samt att äldre byggnader renoveras. Då är det viktigt att inte den större fokusen ligger på den ekonomiska- och ekologiska hållbarheten, utan även på den sociala hållbarheten. Detta för att förebygga ett segregerat samhälle som vi idag ser resultat av och drivs emot. Genom gemensamma bostadsgårdsytor skapar vi nya samlingsplatser. D

The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctu

The Internet has revolutionised the global market place. Internet shopping is now accessible to an increasing numbers of people. In theory, this new form of media offers convenience, speed and choice to the consumer, but the question is whether it works in practice? Business-to-consumer cross-border transactions, whether carried out electronically or otherwise, are subject to the existing framewor

Purpose: The purpose of this study is to explore how brand managers align their brand identity within online brand communities where the communication is shared in order to create a reinforcing point of contact instead of a source of mixed messages. Problem: With the increasing usage of the internet, brand managers are today forced and challenged to align and re-enforce a brand’s identity online w

An alternative energy and chemicals must be found to meet the future demand. A possible source of renewable energy is plant oil since it has a close chemical structure to fossil oil with less refining requirement. However, vegetable oil has not made a significant contribution to replace fossil oil as an energy source because of high demand of fossil oil. It is possible to substitute fossil-based c

In our society, digital cameras are used for a countless number of different purposes. There are many components going in to making such a complex product but one could argue that the camera sensor and lens make out the heart of a digital camera. Axis Communications AB, founded in 1984, is a Swedish company which pioneered and specialize in digital network cameras. In 1996 Axis delivered the first

Denna studie presenterar en detaljerad undersökning av utvecklingen av sedimentära landformer under en ablationssäsong vid Blåisen, en del av Hardangerjøkulen, Norge. Två besök vid Blåisen, i början och i slutet av ablationssäsongen, gjorde det möjligt att studera hur landformerna bevaras och utvecklas. Det pågår mycket forskning om glaciala landformer som är en nyckel till förståelse av hur tidigThis study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. Much research is conducted studying glacial landforms, which are key in our understanding

Popular science summary: Do bacteria survive in humans by eating the defense molecules during the course of infection? Enterococcus faecalis (E. faecalis) is a pathogen that can be found in the human gut which causes a wide range of infections including urinary tract infections, cardiovascular infections and bacteremia (presence of bacterial cells in blood stream). These bacteria can also be fou

Det här examensarbetet i geologi är en studie av ökensediment. Det är tvärvetenskapligt mellan geologi och ekologi. Sedimenten som har studerats kommer från en statlig försöksodling, El Hicha, på saltstäppen utanför El Akarit, 45 km norr om Gabes i södra Tunisien. Första steget i studien var att ta sediementprover på försöksodlingen där Ministry of Rural Engineering, Water and Forest odlar träd oc

Wind power developments in cold and icing conditions pose new challenges to the wind power industry. Icing of wind turbines cause safety hazards, production losses and increased loads. This means that there is a need to develop a technique to quantify the icing climatology and corresponding eects on wind turbines to enable large scale wind power developments in the windy, sparesly populated areas

Läckage och spill från cisterner utgör de vanligaste orsakerna till förorening av grundvatten med petroleumprodukter. Bensin och dieselföroreningar sprids inte enbart längs grundvattenytan utan lösta beståndsdelar kan transporteras med grundvattnet relativt långa sträckor. Flyktiga kolväten förflyttar sig i den vattenmättade zonen beroende på föroreningens utbredning och fördelning. Flera tusen aSpills and leaks from storage tanks constitute the most common groundwater contamination source with petroleum products. Gasoline and diesel pools do not spread extensively along the water table, but dissolved constituents are transported in groundwater on relatively larger distances. Volatile hydrocarbons migrate in the vadose zone dependently on distribution and extent of the dissolved and pure

Detta arbete har som syfte att besvara två frågeställningar - hur ser lagstiftningen ut för miljökonsekvensbeskrivningar för planer och program i Sverige, och vilka krav kan ställas utifrån denna, samt hur dessa krav har uppfattats i genomförda miljökonsekvensbeskrivningar för planer och program? Detta görs genom en genomgång av lagtext, förarbeten, praxis och litteratur på området, en granskning This work aims to answer two questions - how does the legislation for environmental impact assessments for plans and programs in Sweden look like, and what demands can be made from this, and how are these requirements perceived in conducted environmental impact assessments for plans and programs? This is done through a review of the statutory text, legislative history, case law and literature, an

Accessibility is something often taken for granted in our society, but it is a necessity for people with disabilities. Railway stations are a public place and are often a connecting point for several modes of transport. Design of railway stations in terms of accessibility for persons with disabilities is governed by several national and international governing documents. The purpose of this thesis

Background The 2002 EU directive on the energy performance of buildings stipulates that buildings must be energy certified. In order to implement the directive in Sweden it is proposed that a law on the energy certification of buildings be introduced on 1 January 2006. The law shall apply to all buildings where energy is used to condition the indoor climate. However, there are a number of exceptio
