As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

Skoghalls Bruk fick i juni 2005 tillstånd av miljödomstolen att öka kartongproduktionen från 665 000 till 800 000 ton kartong per år. Villkoren för tillståndet var att under en prövotidsperiod bl.a. utreda möjligheten att minska utsläpp till omkringliggande vatten.Syftet med examensarbetet var att kartlägga Skoghalls Bruks avloppssystem med avseende på komplexbildarna EDTA (etylendiamintetraättiksyra) och DTPA (dietylentriaminpentaättiksyra), kväve samt fosfor.Dessutom genomfördes nedbrytningsförsök i luftade dammar i laboratorieskala.För att få en klarare bild av nedbrytningen i Skoghalls Bruks luftade damm gjordes även en molekylviktsfraktionering på inkommande och utgående avloppsvatten.Komplexbildare används inom pappers- och massaindustrin för sin förmåga att binda till sig metalljoner som kan vara skadliga i processen. Metalljoner katalyserar nedbrytningen av väteperoxid i blekningen och påskyndar bildandet av aldehyder i kartongen vilket kan leda till lukt- och smakpåverkan.EDTA och DTPA anses vara stabila ämnen, vilket innebär att de är biologiskt svårnedbrytbara. Under den litteraturstudie som genomfördes fanns motsägande uppgifter angående nedbrytningen av komplexbildare, där vissa menade att de genomgår biologisk nedbrytning, men att det sker mycket långsamt.

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

The aim of this paper is to investigate and analyze practices in multilingual classrooms of mathematics in a compulsory school in Sweden where immigrant students have been known to succeed. The school is situated in a suburban and segregated area outside a major city where pupils come from mainly limited socio-economic backgrounds. The rate of second language learners are 70% of all pupils in this school.By using ethnographic methods, mainly interviews and participant observation, data was collected in four mathematics classrooms which corresponded to consecutive ages of education. The data include field notes and observation of artifacts in the environment as well as interviews and informal conversations with teachers and school leadership. Information from the school website, the authority in charge of quality in Swedish schools (Skolverket) and the municipality were also used.The analysis is based on a socio-political viewpoint that power is relational and reflected within schools.

Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

This paper is about the facades and the streets impact on theexperience of the city and how architects can create cities forthe human kind with simple tools that makes a hugh difference forthe experience of urban space.As the cities are growing in a faster rate and as more people moveto the cities, they will also affect more people. The differentstructures that can be found in the cities therefore gets moreimportant and giving design to city structures also gets morecomplex because of our higher demands on urban functions andcontent. It?s difficult to evaluate the ultimate city structuresince all people experience their city in different ways, butarchitects still should be able to create urban spaces thatis suited for the human kind, just as we can create differentbiotopes for flora and fauna. Therefore there must be generalideas of what the human being experience as good or bad and theseshould be guidelines when designing urban space.Since urban space is something that most people experience everyday it doesn´t always have a clear impact on them.

Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.

The extent by which pet owners follow health care instructions falls within the confines of ?compliance?. The success of any given treatment is in part due to the way in which the owner complies with the instructions received from the advising veterinary professional. Studies abroad have found that the preventative dental care sphere suffers from a low compliance rate. Together with the fact that veterinary staff commonly issue advice on preventative dental care, this provided the impetus for undertaking the current research.

The Swedish dairy sector is facing several challenges the coming years. One big challenge is how they will secure the access of their raw material milk in the future. The number of milk producers has decreased for an extended period of time, but was for a long time partly compensated by an increased productivity among the remaining milk producers. From year 2000 that trend was broken and also the quantity of milk produced started to fall quickly. Milko is a dairy company with members from Dalsland in the south to Jämtland in the north. During the first seven moths 2007, their number of members decreased by almost a fourth, from 1 272 to 974.

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.

Det finns idag en trend i viljan att investera i samhällsfastigheter, det vill säga fastigheter där olika typer av samhällsservice bedrivs. Fördelen med denna typ av investeringar är att ägarna kan teckna långa hyresavtal med kommuner, landsting och staten som hyresgäst, vilket ger säkra kassaflöden i och med låg vakansrisk. Investeringsmarknaden för samhällsfastigheter är relativt ny för privata aktörer då dessa fastigheter tidigare ägdes i princip uteslutande av kommun och landsting, men som idag av olika anledningar valt att sälja och istället hyra tillbaka fastigheten av specialiserade fastighetsägare. Studien syftar till att identifiera de osäkerheter/risker som existerar vid investeringar i samt förvaltande av samhällsfastigheter och främst vårdfastigheter i Sverige. Genom att intervjua aktörer som deltagit i tre studerade transaktioner av vårdfastigheter från 2011 har en investeringskalkyl samt en känslighetsanalys utformats och legat till grund för de slutsatser som dragits.Att investera i samhällsfastigheter har visat sig vara en relativt stabil och säker investering, då de långa kontraktens driftnetton bidrar till att investeringen kan räknas hem redan under första kontraktstiden. Dock med antagande om att inga oväntade kostnader uppstår.

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

The main purpose of this study was to determine the self-estimated levels of knowledge about doping for a group of strength training young adults, and also to get an idea of their attitudes regarding the subject. A part of the purpose was also to investigate the potential associations between knowledge and attitude. Method: To collect information a questionnaire was constructed that was inspired by a similar study and in consultation with the tutor. Questions regarding background, doping and training experiences together with self-esteemed attitudes and knowledge about doping were included. Questionnaires were handed out at gym facilities in central Sweden, and were answered by men and women ages 18 to 35 years.

Njurtransplantation är det enda botande behandlingsalternativet för patienter som befinner sig i kronisk njursviktsstadium 5. Dagens mest använda immunsuppressiva kombinationsbehandling i klinisk praxis består av calcineurinhämmaren takrolimus, mykofenolatmofetil och kortikosteroider i form av prednisolon. Belatacept (Nulojix®) är ett fusionsprotein som introducerades på marknaden 2011 och ska ses som ett alternativ för primär immunsuppressiv behandling. Verkningsmekanismen för belatacept är att hämma aktiveringen av T-celler genom blockera co-stimulatoriska signaler från antigenpresenterande celler. Teorin bakom belatacept är att man genom en mer specifik immunsuppression ska kunna undvika de nefrotoxiska biverkningar som calcineurinhämmarna takrolimus(Prograf®) och ciklosporin(Sandimmun®) ofta ger.
