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.

Today's planning strategy, densification of cities, makes it difficult for municipal authorities to find spaces to build preschools and daycare centers on. The Planning and Building Act , Chapter 8, § 9 states that " if the site should be developed with buildings that contain one or more dwellings or premises for after-school , preschool, school or other activities, it should be on the property or near it, enough free space which is suitable for play and being outdoors. " Each municipality has to define the expression enough free space and a number of municipalities have established guidelines for preschool and daycare centers concerning dimensions. The guidelines measure the number of square meters of free space per child with the aim of contributing to a qualitative environment. But the size is just one quality and the issue is how other non-quantifiable qualities are taken into account in the planning process. The paper compares three municipalities, Gothenburg, Malmö and Lund.

The theory that concepts that are interpreted subjectively in building care creates problems in how the concepts are defined in practice within the current governing documents and guidelines for building care. This essay has studied concepts in the building maintenance literature to investigate whether there is consensus in compliance practice within the building process. In the study, 9 concepts have been investigated through conversational interviews and questionnaires answered by practitioners with extensive experience in building care processes. In the survey, an attempt is made, to measure how big or small the consensus is between practitioners who often need to collaborate within the building maintenance process. The investigation shows that existence of the concepts in building maintenance is very common in the theoretical literature examined but is almost completely absent in the craft area. Since laws, regulations, principles, and guidelines have defined concepts to support the decisions in the building maintenance process, it can be concluded that there is a lack of practice for compliance.

The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

The aim of this thesis is to create an understanding of the incentives for forest companies to invest in reducing carbon dioxide emissions from deforestation and forest degradation, which is termed REDD. The Brazilian Amazonas was chosen as the base for the investment case. Brazil has the largest area of rainforest in the world, and also the biggest problem with deforestation. The Amazon region of Brazil comprises rainforest which is largely intact and unexploited. Accordingly, there is significant potential scope for prospective investments in a REDD-project, and so have a noteworthy impact in preventing deforestation.The research approach used the United Nation?s Clean Development Mechanism concept was used as a framework for ascertaining the investment costs in potential REDD-projects.

Europe has, since the economic crisis of 2007, gained increasing social segregation. The gap between rich and poor has increased and the large number of hidden statistics regarding people excluded from the labor market is greater than in many years. Social exclusion has thus taken a toll on community groups that already before the crisis had a hard time getting included. Groups such as young, elderly, immigrants and people with mental of physical disabilities. To curb this development, the European Commission have, since the 2004 directives, enabled public sector clients to, through procurement of goods, services and contracts, include measures that promote social consideration.Social consideration is a term that have been a part of Swedish procurement legislation since 2007, and was updated in 2010.

The aim of this master thesis is to show how the dissemination of scientific information took place and developed during the 19th century. The main focus is Lund University. Therefore I have formulated two questions: How did the five heads of the history department at Lund University publish their research findings in the 19th century? What factors in society influenced the scientific spreading of results in the 19th century? To assess the scientific reliability of the sources I have used a method based on source criticism and hermeneutics. The thesis covers important concepts such as the exchange of publications between the universities, commercium litterarium and Akademischer Tauschverein and also the development of Lund University yearbook.

The Regional State Archive in Uppsala [Landsarkivet i Uppsala] has several archives left from various types of educational institutions in the counties of Dalarna, Södermanland, Uppsala, Västmanland and Örebro. This archiv-al guide reveals the main content of some of the school archives. It goes through the archives of the elementary school, state secondary grammar schools and private secondary grammar schools. A few special schools for the blind and the deaf children are included. The essay also brings up records from community homes and reformato-ries for children and young adults who experienced certain difficulties and therefore could not adjust to the ordi-nary educational system.

The aim of this essay is to describe and analyse the legal complications that arise in connection with preliminary investigations involving several juvenile offenders, where all suspected persons have not attained the age of criminal liability. It is also intended to give a broad analysis of the concept preliminary investigation, with particular emphasis on juvenile offenders. It further analyses the legislation and legal complications on the basis of a rule of law perspective. The method previously used is court dogmatic, where in front law text, preparatory work, case law and legal doctrine have been used in order to present the existing sources relating to the subject matter of discussion. The criminal investigative bodies consider juvenile offenders are regulated under the Swedish RB 23 - 28 chapters, FUK and LUL.

Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.

Based on the Migration Board's statistics report, the number of children that has gone missing within a time interval of 4 years (2010-2014) comprises 1331 children in total, of whom 146 are girls and 1185 are boys. A rising interest about what has happened to those children created a fundamental platform for this thesis. By reading Åkerman?s report from 2012, and the book De förlorade barnen: en rapport by Mikkelsen and Wagner (2013) the curiosity grew deeper. The research questions that were established were divided into three parts.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).
