Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk
In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.
Mellan stad och hav - kajpromenad i Kalmar
The aim of this project is to investigate the meeting between the city and the sea and tolook into how that could be developed and made use of. I want to find out how you can increase the availability of a specific place and make it more welcoming, I also want to bring life to an already existing space and create a central meeting place in the city. The purpose is to give form to an esplanade along a dock in the central parts of Kalmar. Starting with an analysis of this public place, I want to create a concept that is close to the existing context and communicates the contrasts or associations between for example: city and nature, artificial and natural and indoor and outdoor. The primary object of the project is to add a welcoming, public place to the city where you on an accessible way canfamiliarize yourself with the meeting between the city and the sea.

When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals
Slaughter of animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that animals are declared dead when consciousness is irreversibly lost, and absence of respiration and blood circulation are observed.
Blodbad eller tragedi : Hur fyra skolmassakrer framställs i Aftonbladet och Dagens Nyheter
This survey's main purpose is to highlight how the two Swedish newspapers Aftonbladet and Dagens Nyheter writes and describes four different school shootings. We wanted to find out if there is a general pattern of how school shootings are reported by the media. Two of the shootings occured in USA, Columbine and Virginia Tech, and two in Finland, Kauhajoki and Jokela. The analysis aims at three areas: the whole event, the perpetrator and the victim. We have used a qualitative content analysis with a semiotic model to examine the articles in the survey. The theories in the study is based upon views on social constructionism, media logic, stereotypization, representation, morale panic/media panic and media events.
Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.
The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.
Naturvårdande skötsel (NS) - blir resultatet som man tänkt sig? : en fältstudie över föryngring, trädslagsfördelning och död ved 14 år efter åtgärd
A new Swedish political approach to forestry was initiated 1993, that put goals of production and environmental issues into equal importance to Swedish Forestry Law. Earlier nature conservation very often declaimed preservation the best way to conserve nature, but recently it is clear that many highly biological values are due to former land use or disturbance. Many old pastures or cultivations dominated by deciduous trees are today characterized by a dense overgrowth of Norway spruce. By actively paying attention to nature in forestry (nature restoration), it is possible to partly reconstruct habitats or disturbances that are necessary to favour the biological values.
The aim with this master thesis is to study the nature restoration, (NS, Swedish abbreviation), performed in 11 forest sites in the middle of Sweden 8-14 years ago. Since NS recently have become applied, it has never yet been evaluated.
The impact of the EU Timber Regulation on the Bosnia and Herzegovinian export of processed wood
Illegal logging and its related trade is of great concern around the world. The European Union Timber Regulation (EUTR) is a regulatory approach by the EU to prevent illegal timber and timber products to be placed on the European Union inner market. This means the regulation affects both actors in the member countries as well as the actors exporting timber and timber products to the EU from non EU member countries. This study aims to study the implementation process of the EUTR in Bosnia and Herzegovina (B-H), and its preconditions. Institutional theory is used to understand and explain how the EUTR affects B-H organisations? business environment, and how the organisations choose to respond to the EUTR.
Tillämpning av naturvårdsavtal :
Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature.
The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.

Hårdgörning av Asp
Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en treskiktskonstruktion som motverkar träets fuktrörelser. Dessa skivor har dock visat sig vara instabila och tidigare försök har uppvisat deformationer i form av kupning. Denna undersökning syftar till att utreda förutsättningarna för att använda komprimerad asp samt att ta fram underlag för framtagning av en kommersiell produkt.Praktiska tester har genomförts för att studera hårdhet, återfjädring och densitet hos det komprimerade virket.
Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm
Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..

Det (o)synliga k?net i ledarskap - En intervjustudie om medarbetares uppfattningar om mellanchefers ledarskap inom finanssektorn
The purpose of this study is to investigate how employees in the financial sector perceive the leadership behaviors of middle managers, and if these perceptions differ depending on the manager's gender and if so, in what way. The study is based on a social constructivist perspective and theories of gendered organizational structures. It is based on 15 semi-structured interviews with employees who have either female or male middle managers from different companies in the Swedish financial sector. The results show that gender often acts as a framework for how leadership is evaluated and understood. Female middle managers are frequently associated with relationship-oriented qualities.
