Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Att marknadsföra politik i Sverige : En fallstudie av tre svenska politiska partiers marknadsföringsstrategi gentemot yngre väljare

BackgroundPolitics in some ways has always been about communication and marketing. In Sweden some people believe that communication and meaningful relations with the voters are of no value, instead it is the political content that is of importance. Media evolution has changed the conditions of political marketing; this has meant that the choices of the right communication channels in political marketing have become more important today than ever. Political competition in Sweden has become more even in recent years, this has called for political communication and marketing to be more planed and well thought out. Political parties have therefore begun to spend millions on marketing themselves.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Farmers´ decisions factors : a case study

This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Vadå språkutvecklande arbetssätt? : En studie av tre olika klassers undervisning med fokus på språkutvecklande arbetssätt

In a municipality in the county of Stockholm there is a preparatory class which accepts newly arrived children from other countries. In the preparatory class the education is focused on teaching students the Swedish language so that they eventually, after about 3-4 -terms, can be transferred to a "regular" class.For students with a different native language, it takes about 5-7 years longer to learn the knowledge-based language that is used in school (Gibbons 2009: foreword). This requires education in school to be linguistically developing.The purpose with this essay is to gain knowledge on how pedagogues can work in a linguistically developing manner with students who have Swedish as their second language. The comparison between education in a preparatory class and education in two regular classes at two different schools is also part of that purpose.What is the education considering linguistically developing work methods like in the preparatory class and the" regular" classes? Are there differences and similarities between the preparatory class and "regular" classes education when it comes to linguistically developing work methods? Which part of the education is adapted to a linguistically developing perspective that fits students with Swedish as a second language?Theories as the socio cultural theory, the proximal zone, and Jim Cummins model, concerning among other things language and knowledge development, is brought up and linked to the study of differences and similarities between schools.

What to expect ? A qualitative study of roles in Retail Marketing

Thesis purpose: The purpose of this master thesis is to investigate the expectations of roles between supplier sales representatives and retailer store personnel in relation to in-store campaigns, this in order to enhance effectiveness of these functions creating an increase in consumer response. Methodology: The researchers believe that social phenomenon and their meanings are continually being accomplished by social actors, hence a study of individuals? expectations must have a point of departure in these people?s social reality. Store personnel and supplier sales representatives are to a certain degree affected by the structural power relationships within the organizational network, thus the researchers combine an interpretative and radical structuralist paradigm. Theoretical perspective: The researchers investigate expectations of roles through examining interaction between parties involved.
