Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen
The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.
Dramat i musiken
The aim of this master?s project is to explore ways to perform piano music conceived dramatically. I do this through performance of Beethoven?s Appassionata Op. 57 and of Scriabin?s Piano sonata no.
"My body is and is not mine" : Om könsbinär kontroll i den offentliga debatten kring steriliseringar vid juridiskt könsbyte.
Syftet med denna uppsats har varit att identifiera könsbinära normer tillsammans med kontroll i den svenska debatten kring steriliseringar vid juridiskt könsbyte. De teoretiska utgångspunkterna består av Michel Foucaults begrepp "biomakt", Judith Butlers begrepp "den heterosexuella matrisen" och Beatriz Preciados teori kring kontroll av queera kroppar. Med hjälp av kritisk diskursanalys har debatten analyserats genom en tredimensionell analysmetod. Resultatet och analysen i denna uppsats visar att flera könsbinära diskurser kan identifieras i debatten. Dessa diskurser kan delas in utifrån antaganden om identitet, kropp och funktion.

Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.
Revisionspliktens avskaffande : En obefogad oro?
Since 1987 until November 2010, the entrepreneurs who choose to conduct its? company in the Swedish corporate form aktiebolag had no opportunity to evade or deselect the mandatory audit. The only choice that really was there to make was to which audit firm they would turn to and the Swedish auditor?s position was rather unchallenged. Today the circumstances are different and the small businesses have been given a chance to take charge of their own situation now being able to remove the auditor.
Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes
Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.
Införande av kompostering : en jämförellse mellan två bostadsområden

Effektivitet i grundskolan - en studie om Leans applicerbarhet på processen utvecklingssamtal
Efficiency has become an important objective for many providers of welfare services. Among Swedish schools, both private and public, increased administrative demands seemingly influence operations, and affect teachers negatively through perceived stress. Simultaneously, Swedish students scored an all-time low in the latest PISA survey, and are now performing below the OECD-average in science, mathematics and reading. A central administrative task in the Swedish elementary school is the parent-teacher conference, which is an important activity in supporting the development of the student's knowledge and social skills. Lean is a well-established operations framework, which has proven successful in order to improve process efficiency.
Make not waste: rethink, recycle & redesign
I den här uppsatsen kommer jag berätta om min process att skapa något nytt och unikt av sådant som i vanliga fall anses ha gjort sitt. Syftet med den här processen har varit att vidga mina vyer när det gäller material och deras användningsområden. Att utveckla min egen stil samt inspirera andra att se möjligheter med att återanvända och ta tillvara på sådant som redan finns i vår omgivning. Att kunna se på föremål med nya ögon och placera in dem i nya sammanhang, är något vi alla behöver lära oss mer av. Både för vår egen skull och för vår omgivnings bästa..
Inverkan av torrsubstanshalt och temperatur på kompostens syrabildning :
Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.
Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future
Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient
urban biotopes which also can be used by local urban communities.
The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design
competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields.
In my proposal I applied ecological design principles on three scales:
the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged
material.
Effektivisering av Scuffplatemonteringen på Preciform
Preciform AB är ett legotillverkande företag i Eskilstuna som har specialiserats sig på djupdragning, svetsning, slipning och formning av tunnplåt samt ytbehandling och montering. Företaget har som en del av sin produktion montage av Scuffplate till Volvo XC90-R-design.Från 2012 kommer VCC att ändra utseende på XC90-R-design, vilket innebär för Preciforms del att det blir en förväntad ökning av dagstakten samt att det kommer ställa ökade krav på logistiken runt Scuffplatemonteringen, vilket dagens process inte är anpassad för. Syftet med det här examensarbetet, som är en del av en förstudie på Preciform är att förbättra monteringsprocessen, skapa en överskådlig hantering samt lagerutrymme för ett ökat antal artiklar av ingående material.Tidsstudier av genomloppstid, processtid, godshantering och transporter samt gångstudie genomfördes för att identifiera förbättringsåtgärder, där de olika studierna tjänade som underlag vid beräkningar och jämförelser före och efter implementering av förbättringsåtgärder.Analyser av studierna visade att en av scuffplatemonteringens sex klart avgränsade stationer hade en högre genomloppstid än de andra. Föreslagna förbättringsåtgärder har syftat till att jämna ut takten i monteringsprocessen och reducera waste.En ny layout presenterades och efter viss modifiering implementerades den tillsammans med merparten av förbättringsförslagen.Beräkningar av tillgänglig tid i monteringen visar att en annan arbetsfördelning och indelning av stationer är möjlig i ett fortsatt förbättringsarbete.Jämförelser mellan gammal och ny layout visar på en reduktion av waste i genomloppstiden med 32 procent och en stegreducering med 30 procent.En fortsatt verksamhetsutveckling kommer att reducera tid och steg ytterligare. Resultaten av vidtagna förbättringsåtgärder kan utgöra grunden för en ny förbättringsprocess enligt principerna för Demings hjul.
Sjuksköterskors erfarenhet av att vårda patienter med självskadebeteende
The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.
