Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

Research shows that almost 30 per cent men and 20 per cent women at the age of 16-24 in Sweden download music on a regular basis instead of buying records. Thanks to modern technologies teenagers of today have become used to downloading music illegally from theInternet. Even though legal alternatives, such as Spotify, have become popular, the behavior of illegal download of music still persists. What do record companies do to prevent this phenomenon and why do they go to such length to stop this widespread movement? The question is, why is illegal download of music a problem ? and for whom? To investigate this I?ve read books about the subject, analyzed web pages of alternative record companies and interviewed a drummer in a local band.

In this thesis, the impact of collective ratings on customers? perception of a product is examined. The empirical data comes from an experimentally designed survey where the effect of collective ratings is measured in the setting of a traditional advertisement for a feature film. In contrast to what previous research would suggest be to the expected outcome, the authors of this paper concludes that in comparison with alternative designs of advertisements, there are no measurable advantages of including collective ratings in advertisements from the marketers point of view. We find two explanations to the result: (1) people tend to self-report that they are more influenced by collective ratings than they actually are, and (2) the advertisement which lacked a rating could be as attractive due to cultural interpretations of white spaces..

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

A large part of Sweden?s green, urban landscape is covered by lawns. Approximately 80 000 ha of maintained grass lawns are part of public courtyards, schoolyards, parks, golf courses, sport fields and traffic environments. Beyond this figure, the lawn is also an essential element in most private villa-gardens. Lawns have become a universal phenomenon through the dispersion of landscape aesthetics from the Western world.

Syfte: Syftet var att undersöka prevalensen av katarakt i Bolivia under en resa med den svenska hjälporganisationen Vision For All.Metod: Undersökningarna utfördes med hjälp av handhållet oftalmoskop av modellen Heine Beta 200S. Undersökningen genomfördes i genomfallande ljus på ca 30 cm avstånd mellan patient och undersökare. De eventuella opaciteterna i linsen graderades efter hur omfattande de var där grad 0 var inga opaciteter och grad 4 var helt opak lins och grad 5 visade att linsen inte kunde undersökas på grund av oklar hornhinna eller dylikt. Patienterna sökte själva upp undersökningsplatserna som var belägna i städerna Santa Cruz de la Sierra och San José de Chiquitos. Eftersom det fanns begränsat med plats i bagageutrymmet på resan till Bolivia, valdes en väldigt enkel metod som inte krävde avancerad utrustning.Resultat: Totalt medverkade 453 personer i studien, det vill säga 906 ögon.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Den ekologiska produktionen styrs av många olika lagar och regler som den konventionella produktionen inte behöver följa. Dessa regler kan ses som en välfärdsgaranti i den ekologiska slaktkycklingproduktionen då reglerna främst är skrivna för att kycklingarna ska kunna utföra sina naturliga beteenden i en passande miljö. Rastgårdar ska finnas till de ekologiska kycklingarna för att de ska få beta, få motion och få chansen att bygga upp sitt naturliga immunförsvar. I många fall ses rastgården som en positiv aspekt av den ekologiska produktionen, men det finns även problem relaterade till utevistelsen då exempelvis vilda djur kan lockas till slaktkycklingarna och på så vis stressa upp dem, smitta dem med parasiter och patogener eller äta upp dem. Det är vedertaget att den ekologiska produktionens dödlighet är högre än den konventionella produktionens på grund av rovdjuren och sjukdomarna och de ekologiska kycklingarna utsätts i många fall för fler smittorisker på grund av utevistelsen.

Alzheimers sjukdom (AD) är den vanligaste formen av demens och kännetecknas av intracellulärt neurofibrillärt trassel (NFT) bestående av proteinet tau och extracellulära plack, uppbyggda av peptiden amyloid beta (A?). En växande skara studier har börjat peka mot att AD är en hjärnspecifik typ av diabetes. Insulinresistens följt av hyperinsulinemi och hyperglykemi är kännetecken för diabetes mellitus typ 2 (DMT2) och har visat sig vara en riskfaktor för AD. Insulin, ett hormon som kontrollerar glukoshomeostasen i perifera nervsystemet (PNS) och är viktigt för minne och inlärning, transporteras över blod-hjärnbarriären i en mättnadsbar transportmekanism och dess koncentration i centrala nervsystemet (CNS) minskar vid DMT2 och AD.

The kitchen is one of the most important rooms in our homes. It is a place for social engagements, meetings between people and activity. How the kitchen looks today is a concept sprung from the Swedish kitchen standard of 1952. Eventhou this standard no longer exists it is a model of how kitchens are designed today. The kitchens most often sold today come from one of four major kitchen manufacturers in Sweden.My thesis investiges an alternative kitchen concept.

Under den senaste tiden har det svenska beteskravet varit omdiskuterat. Många lantbrukare ser beteskravet som ett problem och har löst det genom att endast erbjuda sina kor en liten rastfålla där de har tillgång till utevistelse och fysisk aktivitet. Syftet med denna studie var att undersöka deltidsbete i en besättning med automatisk mjölkning. Rastbete jämfördes med produktionsbete med avseende på mjölkavkastning, mjölksammansättning, foderkonsumtion och betesbeteende. Korna i båda behandlingarna (rastbete och produktionsbete) erbjöds bete under 9,5 h/dygn.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Urbanisation has increased the distance between the urban and the rural. Urban agriculture can be a solution to overcome that distance. The characteristic of urban agriculture is the intensive production in intra urban and peri-urban areas. Until 1950s food production in cities was an important part of the urban economy and the urban food supply. Since the 1950s the urban located production of food has almost ceased in Sweden, partly as a result of cheap food imports.

This essay examines the Swedish debate on Internet hate with focus on theories concerning Internet as a public sphere, sociocultural turbulence and subaltern counterpublics. Examining material fromnewspapers, alternative news media and discussion forums, with an hermeneutical influenced method, the task is to understand the Internet hate debate, and the study wishes to discover its relations to biggercontexts, such as social transformations and power dynamics. The conflict evolves between the establishment (journalists, writers, politicians et cetera) on one part, and Internet ?haters? on the other.The examined theme also shows a conflict where the two combatants show not only two opposite views on what Internet hate is, but also shows two different conceptions of the world..
