Riktlinjer för enskilt avlopp : Underlag för bedömning av normal och hög skyddsnivå i Köpings kommun
In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.
Gaspotentialen i en deponi, idag och i en framtid :
Deposited waste material degrades within a short period in anaerobic environments. The
methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas.
In this thesis the amount of produced methane gas at the landfill at Örebro has been
calculated. Estimations have also been made of the amount of methane gas that might be
produced in the landfill in the future.
Representationer av migranter inom biblioteks- och informationsvetenskaplig forskning : En textanalys utifrån kritiska ras- och vithetsstudier och intersektionell teori
The purpose of the essay has been to examine representations of immigrants in contemporary library and information science research in a Scandinavian context. By analyzing nine articles from the past decade we examine the perceptions that exist in the concepts of multiculturalism, culture, race, ethnicity, religion, gender and whiteness and what role and importance the library as a place is assigned in relation to immigrants as a user group. Our study consists of a qualitative text analysis, a critical oriented close reading method based on critical race and whiteness studies and intersectional theory. We have, with the help of Sara Ahmed´s theories of hegemonic whiteness, demonstrated how multiculturalism is partly presented as something desirable and good, partly as something potentially threatening.The discourse of multiculturalism can be said to express the notions of the other, which in the source material manifests itself by ascribing otherness to immigrants. We have, for example, examined how ethnical and cultural differences are highlighted by a separation of East and West, the library?s educational and assisting role in relation to immigrants as a user group as well as representations of whiteness, gender and clothes.
Kartläggning och effektivisering av ljuddämparflöde
In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.
Aktioner och reaktioner - Kristna kvinnors motreaktioner till Femens aktioner i en proteströrelse på internet
Religion is not only manifested in the more traditional forms such as church attendance, but also in various expressions on social media. Facebook is seen by many as creating a social platform where different opinions and more unconventional discussions may flourish unlike how the traditional media convey information. Internet is therefore an interesting platform for investigating how information about religion is spread by researching religious behavior and expression. The focus of this essay is to examine visible, which includes text as a social practice, forms of religious expression shown by the discursive struggle between the Facebook-group Christian Women Against Femen and its counterpart feminist movement Femen. The essay seeks to answer how notions of femininity on the Internet are formulated and reproduced based on the discourse between these two women's movements.The essay highlights how the women?s movements, with their bodily manifestation and by their usage of words, construct and reproduce different images of gender and womanhood.
Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp
Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.
För att veta vad någonting är måste man veta vad det inte är : En studie om hur några elever i årskurs 1 lär sig vad ett tekniskt föremål är
Syftet med denna studie är att undersöka hur några elever i årskurs 1 skapar förståelse för vad en teknisk artefakt är och vidare hur eleverna ges möjlighet till detta genom att läraren använder variationsmönster under ett lektionstillfälle. Materialet har samlats in genom en learning study vilket innebär att vi har genomfört en praxisnära undersökning. Vi har i studien agerat både forskare och lärare; observerat, planerat och bedrivit undervisning samt analyserat empirin. Vi har studerat tre lektionstillfällen i tre olika grupper med fokus på att tillsammans med eleverna skapa en definition av vad en teknisk artefakt är. Med hjälp av för- och eftertester har vi även undersökt elevernas uppfattningar om tekniska artefakter före och efter lektionstillfället.
Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori
The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.
Produktutvecklingsmetoder för industriellt restmaterial
Rapporten behandlar framtagandet av en produktutvecklingsmetod för industriellt restmaterial. Studien har gjorts på uppdrag av Creatables som är ett projekt inom företaget KAAV AB.Creatables arbetar med att ta fram konsumentprodukter genom att ta tillvara och förädla restmaterial från industrin, därav deras slogan Made from Waste.Dagens konsumtionssamhälle förbrukar mycket av jordens resurser och det krävs en effektivisering i utnyttjandet av dessa för att säkra tillgångar för framtida generationer. Creatables är ett ungt projekt med små resurser och således har syftet med examensarbetet varit att ta fram en ny produktutvecklingsmetod för Creatables anpassad till deras arbetssätt och storlek.För att utreda uppgiften har arbetet delats in i två delar som sedan utvecklats parallellt med varandra. En produktutvecklingsmetod och ett flertal produkter av restmaterial har arbetets fram.Litteraturstudier, intervjuer och studiebesök har genomförts för att bygga en grund för resultatet att stå på. Tidigare publicerade teorier om produktutveckling har studerats och informationen och resultaten från dessa har i kombination med produktutvecklingsarbetet använts för att ta fram en produktutvecklingsmetod som passar Creatables.Resultatet är indelat i tre huvudområden.
Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet
General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.
Kundnöjdhet i revision: En jämförelse mellan företag som reviderats av Big Four och företag som reviderats av någon annan revisionsbyrå
The need for auditing originates from the agency problem that arises due to the separation of ownership and control in companies. The purpose of the audit is to increase credibility of the financial statements that management uses to communicate with owners and other stakeholders. In order for the audit to fulfill its purpose a certain level of quality needs to be obtained. The auditor can also be seen as a provider of a commercial service in which service quality is important. Audit quality can thus be separated into technical quality, which is defined as the probability that the auditor both discovers and reports a breach in the client?s accounting system, and service quality, which relates to the provision of services in general.
Energianalys av Svensk Växtkrafts biogasanläggning i Västerås
Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase
their treatment capacity at their biogas plant. In connection to this work it is also possible to make
some energy saving changes to the biogas plant. The objective of this study was therefore to make
an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the
sanitation step and also a comparison of energy consumption with the present sanitation method
and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method
is heating to 70 °C during 1 hour).
The energy survey was conducted in close collaboration with staff at the biogas plant. The current
during normal operation was measured, power was calculated and multiplied by the time of usage to
obtain the energy consumed.
Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case.
A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety
of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle
perspective is applied.
