Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk

Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants.In the waste water treatment process solid material and dissolved pollutants are separated from the water, forming a sludge. The sludge is separated from the process and stabilized during anaerobic digestion or aerobic aeration. Most often, mesophilic anaerobic digestion is used. Because of degradation by microorganisms, biogas with a high content of methane is formed during the digestion.

Ämnestransport med grundvatten i hydrogeologiska typmiljöer

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

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.

En europeisk åklagare : ett hot mot den fria bevisprövningen?

There are intense discussions within the European Union regarding the introduction of a European Public Prosecutor (EPP). The proposed EPP will have jurisdiction in the entire union, and will work under a unified set of rules of procedure. These procedural rules will differ from the Swedish rules of criminal procedure, especially regarding the handling of illegal evidence. The thesis describes the European legal history, especially regarding criminal procedure. The thesis also describes what the purposes and principals are in Swedish criminal procedural law, and the purposes and principals in the proposed European criminal procedural law.

Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.


Kvalificerad sexuell handling : med samlag som jämförelsenorm

Brottet våldtäkt består i att någon genom tvång eller utnyttjande företar en sexuell handling. Alla sexuella handlingar utgör dock inte våldtäkt, utan handlingen måste vara av en viss allvarlighetsgrad. De sexuella handlingar som faller under bestämmelsen om våldtäkt benämns ibland kvalificerade. Andra sexuella handlingar, som exempelvis de som rubriceras som sexuellt tvång, kallas således icke kvalificerade. En sexuell handling är kvalificerad om den med hänsyn till kränkningens allvar är jämförlig med samlag.

Trygghet i relation till pedagogisk handling : En hermeneutisk tolkning av trygghetsbegreppet relaterad till pedagogisk handling

I den här studien har vi, med hermeneutisk filosofisk forskningsansats och kvalitativ intervju som metod, undersökt hur begreppet trygghet kan tolkas och användas i relation till pedagogisk handling. Hur pedagogens syn på trygghetsbegreppet kan visa sig i lärandesituationen mellan barn och pedagog. Intresset för begreppet trygghet växte fram från egna minnen från vår första tid i skolan då vi drog oss till minnes att trygghet var viktigt för att vilja lära. Med hermeneutiken som forskningsansats används och problematiseras vår egen förförståelse kontinuerligt med egna reflektioner och tolkningar genom hela processen. Studien behandlar och problematiserar teoretiska perspektiv av begreppet trygghet och begreppet lärande.

Läroböckernas skildring av Irakkriget : En narrativanalytisk studie

Studien undersöker hur Irakkriget,den väpnande konflikten mellan Irak och främst USA och Storbritannien, skildras i läroböcker för grundkursen i ämnet historia på gymnasieskolan. Utgående från Lennart Hellspongs berättelseanalys analyseras skildringarna av kriget i läroböckerna utifrån tre teman: Handling, Aktörer och Värdering. Undersökningen visar både på likheter och skillnader mellan texterna. Undersökningen bygger på en analys av 12 läroböcker för gymnasieskolan i ämnet historia och visar, bland annat, att skildringen av handling och krigets händelseförlopp börjar med olika händelser. Ur analysen går även att urskilja att läroböckerna anser att ockupationen inte var rättfärdigat då USA anföll Irak utan FN:s medgivande samt att det är USA eller George W.

Positive reinforcement training for laboratory mice

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

A material-balance was analysed according tothe flowchart of the production.

Små mängder primärprodukter : vad innebär det?

In article 1.2 c) EC regulation 852/2004 it says that the regulation is not applicable to producers who directly supply small quantities of primary products to the final consumer or to the local retailers who in their turn directly supply the final consumer. An almost identical regulation can be found in article 1.3 c) EC regulation 853/2004. The supply by a primary producer of small quantities of primary products, of animal origin or not, are consequently excepted from these two hygiene regulations. In article 1.3 EC regulation 852/2004 and article 1.4 EC regulation 853/2004 it says that the member states are to establish national rules in their national legislation as to the regulation of exception for small quantities. The aim of this study was to investigate the handling of small quantities of primary products distributed locally in Sweden but also the handling of these products in other countries.

Hur en okontrollerad expansion av IT-projekts omfattning undviks

Today there is an even higher demand on IT-projects success rate compared to a few years ago. IT-projects must be handled more efficiently and result in a more profitable investment. In order to make the handling of IT-projects more efficient and create profitability the developers must have a broad understanding of the IT-projects characteristics and which factors that affect the result of the projects. Changes within IT-projects are often carried out through the development of a system. Since this change is more common when it comes to IT-projects it is important to handle risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes.

Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder

The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage (AMD). This water may reach the nearest surroundings and cause negative environmental effects. By covering the waste with soil or water, the oxidation process can be minimised. At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between 1951 and 1991.
