Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Tala är silver, tiga är guld En studie om förhandlingsprocessen mellan offentliga och privata parter i Danmarks första Public-Private Partnership

The purpose of this thesis is to describe and to increase the understanding of the negotiation process between the public- and the private sector in a Public-Private Partnership (PPP). I have chosen to explore the first ?real? PPP project in Denmark, the construction of Vildbjerg compulsory school in the municipality of Trehøje.This case study is based upon a qualitative method consisting of interviews with the leading negotiators from both sectors. Two different theoretical perspectives are used to construct the basis of the analysis - The Theory of Public-Private Partnership and Negotiation theory - and serve as a concept instrument.The result of the analysis indicates that the negotiators from the different sectors have problems to get out of their traditional roles as purchaser and contractor ? in PPP they should act like partners.

Siktning som saneringsmetod för metallförorenad mark

Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

Välfärd i ekologisk och konventionell grishållning :

Organic animal husbandry has received a lot of criticism lately. The aim of this literature review was to examine if the rules and principles of organic pig farming give better or worse welfare in comparison to the conventional systems in Sweden. Health, physiology and behaviour have been used as indicators of welfare in this study. This is due to the importance of using more than one indicator in welfare assessments. Studies have shown that organic pigs have more remarks on joints when slaughtered, but these remarks can be reduced by vaccination against erysipelas.

Tiga är silver men tala är guld : en undersökning av kunskapsförvandling i projektbaserade företag

Tacit knowledge refers to the knowledge that is located inside individuals; it is not expressed or written like explicit knowledge. Inherently, tacit knowledge is often limited solely to one person and consequently individually based. Project based companies need to acknowledge the importance of transforming tacit knowledge into explicit in order to preserve the knowledge inside the organisation. If the knowledge is not transformed, there is a great risk of losing the knowledge when a key individual leaves the organization.One way of transforming the tacit knowledge is through Nonaka?s and Takeuchi?s knowledge spiral.

Occurrence of Verotoxin-encoding phages in mussels grown downstream the sewage treatment plant in Lysekil

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.

Skogsbolagens syn på vindskadeförebyggande åtgärder efter stormen Dagmar

On the night of the 26th December 2011, large parts of southern Norrland were struck by the storm ?Dagmar? that caused serious damage to the forests. In the past 10 years wind damage has become a hot topic after several major storms. Forest companies own 25% of the Swedish forest and thus influenced largely by wind damage. The main purpose of this study was to examine whether forest companies attitude towards preventive wind damage actions were changed after the storm ?Dagmar?. The result was developed by doing interviews with two forestry companies.

Fjäder Ur Den Dödas Dräkt : En undersökning av Per Bäckströms Öijerska poetik i SVART SOM SILVER

The purpose of this study is to survey how the Sweden Democrats? success in the latest election to the Swedish parliament has changed teaching in social science. The main question is: in what way has the success of the Sweden Democrats influenced social science teaching? This leads to following sub-questions: 1) how do the social science teachers define the Sweden Democrats, 2) how do teachers relate to the Sweden Democrats in the classroom, 3) has there been a change in students? political opinions and 4) were there any discussions or proposals from the school administration which followed the parliamentary election of 2010? To answer these questions, interviews were made with four teachers. The main conclusion of this study is that the Sweden Democrats? success led to a simplification of teaching because phenomena and opinions that were previously taboo nowadays are normalized and thus have its place in the classroom.

Metodik för bakteriologisk provtagning från näshålan på får :

Respiratory infections are one of the major causes of disease in sheep throughout the world. In the beginning of 2008 the Swedish National Veterinary Institute and the Swedish Animal Health Service together started a project about respiratory infections in Swedish sheep. This study is an initial part of that project and the aim of this study was to investigate different sampling possibilities with focus on nasal swabs. This study is composed partly of a literature review on causative agents of respiratory infections in sheep and existing sampling methods, and partly of an experimental study comprising 56 sheep. These sheep were sampled with both an ordinary nasal swab and a guarded nasal swab. Before the start of this study there was to our knowledge no described method for sampling sheep with a guarded swab.

Smitthantering av resistenta bakterier : En fallstudie av ett svenskt universitetssjukhus

Smittsamma sjukdomar kostar det svenska samhället enorma summor varje år. Behandlingen av smittade patienter har tidigare uppskattats till 5-10 miljarder svenska kronor årligen. Vidare estimeras de förebyggande åtgärderna kosta samhället runt en miljard svenska kronor. Detta betyder att det finns en ekonomisk drivkraft för att reducera antalet smittade patienter inom vården, speciellt de fall som är orsakade av resistenta bakterier. Samtidigt pågår det en debatt om resistenta bakterier och antibiotikaförbrukningen i både forskning och media.

MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?

The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.

Historien om samerna : Föreställningen om samerna och samernas historia i svenska läroböcker 

The Sami people are a national minority in Sweden, but are also considered as native citizens of Sweden, Norway, Finland and Russia. The world has however a very limited knowledge about the Sami?s and their cultural background.The aim of this proposal is to examine six different history schoolbooks which depict the Sami people in Sweden. In addition, one of the key elements of this proposal is to understand how the selected literature represents the Sami people.Lastly, the proposal also seeks to review if the literature in the schoolbooks represents the elementary curriculum goals (Lpo94).The selected method was to do a text analysis of the literature and to illustrate that is presented in the reviewed schoolbooks. The text analysis is completed with an analysis of the illustrations and pictures that are presented in the selected schoolbooks.The key findings were that the review in majority of schoolbooks has stereotypical descriptions of the Sami people. The Sami people are generally depicted with the hut and the reindeer management in majority of the reviewed schoolbooks.The research about the Sami people is inappreciable in majority of the reviewed literature. In addition, the Sami people are often presented in connection with ?other? history, such as the silver ore in the mines or the territory dispute with settlers from the south of Sweden.

Vinterförvaring av Pelargonium x hortorum :

There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.
