This thesis concerns the Gotlandic hill-forts (sw. fornborg) situated on a cliff or in an elevated position and which traditionally have been referred to as cliff-forts (sw. klintborg/höjdborg). The study derives from the notion that these monuments, diverse in size and shape, by archaeologists have been viewed and treated as a homogeneous category of ancient remains. The author?s key aim is to challenge this perception by identifying various subcategories from the 28 cliff-forts on the island.Ever since the archaeological discipline initiated the study of cliff-forts in the late 1800s and more or less to present day, the interpretations have been almost solely dominated by explanations of the military and defendable nature of them.

This essay focus on the social media Twitter and how three Swedish PR practitioners view and use communication strategies for this social media. Twitter was created 2006 and is kind of a new channel in the digital world. The micro blog has over these few years attracted 175 million users across the world. In Sweden there is 91 000 registered users and according to a survey, 11 000 of them are active by tweeting once a day.Twitter is highly current and all kinds of people are using the social media, for example, artists, companies and individuals. Twitter is with its highly number of users building a new market for organizations to find their stakeholders.

Denna studies övergripande syfte är att studera hur personer som härbärgerar flyktingar ser på relationen mellan individers handlingar och hela samhällets ansvar för flyktingarna. För att uppnå syftet studeras tre mer konkreta frågeställningar; hur människor som härbärgerar papperslösa finner legitimitet för sin handling, hur de tror att andra människor i samhället ser på deras engagemang och vad de själva tycker om människor som inte är engagerade i detta. Studiens teoretiska utgångspunkt bygger på Jürgen Habermas arbete för att begreppsligöra civil olydnad. I syfte att sätta in dessa i en förståelse hur informanterna ser på sig själva i relation till samhället används också Georg Simmels teoretiska tankar om samhället utifrån hans begrepp; kristallisering, dubbel kategorisering av människor och församhälleligande (vergesellschaftung). Som metod för att samla in studiens källmaterial används en tematiskt öppen intervju. Kodning och analys genomförs med så kallad databaserad kodning, som sedan med hjälp av identifierbara underteman (antingen förbestämda eller skapade av informanterna) försöker bena ut en tankestruktur hos informanterna som kan besvara på studiens frågor.Resultatet av studien visar att legitimeringen har två delar. En är att de bistår med akuta åtgärder som exempelvis tak över huvudet för människor i nöd, den andra är att de vill ändra "systemet" på längre sikt.  När det gäller den andra frågan, menar informanterna att de i många fall beskrivs som hjältar av andra. Den sista frågan kan delas upp i två delar.

At seed-growing the aim is to produce a commodity with high germination capacity, good soundness and purity, and also slight admixture of seeds from other species. The capacity of germination and the vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases, growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can be due to the fact that the seeds are in rest of germination, i.e.

AbstractDuring the last five years there has been a considerable immigration from the Netherlands to Värmland in Sweden. INVA, Invest in Värmland, wanted to highlight this phenomenon and therefore contacted Karlstad University to make a survey about how extensive the immigration is and what consequences it brings for the business life and municipalities in Värmland. We were luckily chosen to perform this research and the main focus in this study has been the following questions:? Why do the Dutchmen choose to buy their house in Värmland?? What are the main reasons for leaving the Netherlands?? What consequences does the immigration cause for the business life in Värmland?? How do the Dutchmen experience the contact with Swedish authorities?To answer the questions we designed a questionnaire that was sent to 200 Dutch house purchasers. The ambition was to survey all the Dutch house purchasers in Värmland, but with the time constrains and the municipalities having problem to find complete data, we limited the survey to 200 households.

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.

The aim of this master thesis is to analyze how and why Scandinavian-American history has been used in exhibitions in both Scandinavia and the United States after the end of the Great Migration. More specifically, the thesis deals with the Swedish and American exhibitions of the controversial Kensington Rune Stone, discovered in Minnesota in 1898. Despite the fact that its authenticity has been disputed by academic expertise, it has been displayed by many prominent actors. The Rune Stone is one of many purportedly pre-Columbian artifacts found in the United States. Moreover, it is an identity marker, harboring many kinds of identity constructions. The thesis therefore focuses on the meanings that the Rune Stone has been charged with since its discovery, as historical culture and in specific exhibits, on how it has been displayed, and on why it has been exhibited at  national museums in both Sweden and the United States. The principal source materials are five exhibitions of the Kensington Rune Stone.

Uganda is one country with fastest growing populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way. The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.

Uppsatsen syftar till att undersöka svenska ungdomars motiv till att emigrera till andra länder i världen, där resesyftet inte är arbete, studie eller relation - relaterat. För att skapa en grund till undersökningen så har sekundär data i form av en rapport från SOM-institutet vid Göteborg Universitet analyserats, där statistik och fakta på svensk emigration under de senaste decennierna presenteras. Med detta som bakgrund har vi sedan gjort en kvalitativ undersökning genom semistrukturerade intervjuer med fem olika respondenter som alla har spenderat en tid utomlands utan att ha rest med arbete, studier eller en relation som motiv. Det vi menade att ta reda på genom att intervjua respondenterna var kortfattat deras motiv till emigration, med frågor som om hur idén uppstod, vilka andra drivkrafter fanns samt vilka mål och förväntningar respondenterna hade och om dessa uppfylldes. Det vi har fått fram har sedan ställts mot teorier på bland annat resemotiv, emigration, mobilitet samt den resandens identitet.Resultatet vi fick fram från den sekundära datan visade att Sverige likt resten av världen är på väg in i en emigrations-era och att vi likt många andra nordiska länder har en stigande siffra vad det gäller emigration, och att denna siffra till stor del består av unga personer.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Uppsatsen syfte är att undersöka mötet mellan feministisk religionsfilosofi och frågan om religiös mångfald. Utgångspunkten för uppsatsen är religionsfilosofiska texter av Pamela Sue Anderson och Grace Jantzen och dessa texter får här representera och ligga till grund för en feministisk religionsfilosofi. Som representant för det filosofiska samtalet om religiös mångfald använder jag mig av Mikael Stenmarks översikt över den typologi som präglar det filosofiska samtalet om religiös mångfald. Uppsatsens frågeställning lyder: Vad kan en feministisk religionsfilosofi som tar sin utgångspunkt i Grace Jantzens och Pamela Sue Andersons religionsfilosofiska texter bidra med till det filosofiska samtalet om religiös mångfald?Genom att läsa Andersons och Jantzens litteratur svarar jag för det första på hur en feministisk religionsfilosofi som tar sin utgångspunkt i Andersons och Jantzens texter skulle kunna se ut.

This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

Syftet med den här uppsatsen var att genom en litteraturstudie undersöka vilka huvudsakliga förklaringar som fanns till unga vuxnas psykiska ohälsa. Det var också av intresse att få se om det fanns någon skillnad i sättet att förklara orsakerna till psykisk ohälsa hos män respektive kvinnor. Studien innehöll artiklar ur Läkartidningen, Psykologtidningen, Transmittorn samt en rapport från SOU. Resultatet visade att unga vuxnas psykiska ohälsa bottnade till stor del i ett allt mer individualiserat samhälle. Det hade lett till att ett stort ansvar, många gånger högt över vad individen mäktade med, hade lagts ned på individnivå.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
