This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.

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.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The competition in the milk industry has increased during the last couple of years. This is a result of the trade barrier that dissolved when Sweden entered the European Union. The membership signifies an increased internationalization for the dairies, which has also increased the existence of low price chains in the Swedish food market. The increased share of private brands has strengthened the competitive situation for the manufacturer- owned brands. Three of Sweden?s seven largest dairies have now decided to launch a low price milk to cope with the competitive situation.

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.

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

This thesis is a cultural theoretical case study of the art project (O)önskad samhällsförbättring.Via an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art has plaid an important role in what is called the creative city; to become attractive nodal points of the global economy, larger cities increasingly invest in art,culture and creative industry. Simultaneously the urban public space is limited to activitiesand expressions of art that are presumed to create economic growth. This introduces animpression of what is allowed and what is not allowed, possible and not possible, wished andnot wished which, as a consequence, evolves the public space. The events during the artproject and the reactions that followed enlightened these limitations. This tells a story, not only about the structuring process of the local urban space, but also important changes that are created as a simultaneous effect at different levels in society, as well locally as globally.

The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure. The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

Title AB Volvo Pentas packaging system ?process and packaging logisticsAuthor Peter Powell, Lund's Technical CollegeSupervisors Annika Olsson, Lund's Technical CollegeJan Svensson, AB Volvo PentaProblem - Packaging requirements ? Which requirements are there, how do they affect each other and how are they fulfilled?- Packaging process ? what is the line of action when developing new packaging and making adjustments in existing ones? Who has the responsibility to do what?- Packaging logistics ? How is the packaging system adapted to transport efficiency and handling?Objective To create an overall picture over how the packaging system affects and is affected by different functions and players within and beyond the company boundaries, to give a clear picture of how changes in the packaging system is made today and how it could work and finally to give suggestions for cost savings affected by the packaging system.Method The methods used for this thesis has mainly consisted of action research and at some extent case studies. As a previous employee at the department of logistics at Volvo Penta I?ve taken part of the environment, information and prerequisites that this thesis discusses on a daily basis. Case studies have been used for the collection and analysis of data concerning packaging logistics as I?ve chosen to consider only specific markets and packaging.Conclusions This thesis has highlighted the demands that are placed upon engine packaging throughout all concerned units and how these demands affect each other, positively and negatively.

The milk production has developed rapidly the last years. The milk production per cow is increasing and the production units are larger with an increasing number of animals and a decreasing number of workers. Many milk producers invest in automatic milking systems (AM) to meet this change. In these systems the cows can voluntary decide milking frequency and usually the milking frequency are higher than two times per day. But how does the milking frequency effect the composition of the milk? The aim of the present study was to study the effect of milking frequency on the milk composition and the milk fat quality.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

A study of family therapist?s knowledge retrieval and the application of evidence-based practice.Supervisor: Jan Petersson Assessor: Peter HultgrenDuring our research we discovered that a very small amount of research had been conducted about the effect of the social services. It inspired us to fulfill this study. The aim of the study is to describe and analyze what knowledge family therapists in two Swedish municipalities use in family therapy work.

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
