Utformning av hamnområdet i Arvika : stadsbild och offentliga miljöer
The harbour in Arvika is closed down and the industry that has been established in the area is now beeing wound up. A deepened comprehensive plan for the area is under progress in the municipality. The intentions are for instance that the harbour should be integrated with the city and that Arvika is facing a lake should be more apparent from the city center. The harbour should also contribute to a more attractive city. These intentions have hence been the starting point of my undergraduate theses, which has resulted in a proposal on how to develop the harbour.
During the process I have analysed the city image, how the area is used today and the public places in the city centre.
Butikskoncept : - och det mervärde det skapar
Konsumenterna i studien visar på en mångfald av beteenden när det kommer till hur de påverkas av butikskonceptet. Upplevelserna i butikerna är många och varierar mellan konsumenterna. Olika typer av konsumtion skildras, bland annat genomförs nöjesshopping och målorienterad shopping av konsumenterna i studien. Syftet med uppsatsen är att skapa en förståelse och ge insikt i hur konsumenters beteende kan påverkas av butikskoncept. Butikskoncept är ett bredare perspektiv av butiksmiljön som dessutom innefattar sociala faktorer.
Från strandhugg till säsongsboplatser : En studie av människornas utnyttjande av Gladö på Södertörn under äldsta stenålder
This paper deals with the early mesolithic sites in Gladö, a part of Hanveden situated south of Stockholm. It tries to explain the big amount of sites, why people came to these islands and what they were doing there. The large shore displacement together with the topography of the mesolithic islands resulted in a rapid change of suitible areas for camping. The prime occupation was sealhunting on the ice of the Ancylus lake in early spring. As the archipelago became larger other activities as fishing and birdhunting got more important and people stayed for longer periods..
Jordbruk och järnproduktion i Jämtland : Två näringar i södra Storsjöbygden under folkvandringstid
This essay is about two areas called Hackås and Myrviken, situated in the middle of Sweden around the lake Storsjön. In Hackås we can see traces after an early agrarian settlement, and in Myrviken we find Jämtlands largest concentration of ironmaking sites from around 400 AD. There are no clear evidence of the agrarian settlement in Myrviken, and only two ironmaking sites in Hackås. These two economies functioned at the same time, but were clearly separated. My purpose is to discuss if it was the farmers of Hackås who made iron in Myrviken, or if it was somebody else..
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.
Karakterisering och klassificering av gotländska ytvatten enligt ramdirektivet för vatten
In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.
A matter of trust : social interaction in a nature conservation issue in the Eastern slopes of Lake Vättern
Nature conservation issues are often complex and difficult to handle. Different actors andinterests are involved and it is generally agreed that constructive interaction is a crucialpart of dealing with these issues. According the theory which forms the basis of this thesis,conflict is defined as social interaction during which the actors trust in the interaction isdecreasing. Signs of conflict and diminished trust in the interaction are that these actorsmake attempts to change the situation and some of these attempts can lead to increasedconflict.The aim of this thesis is to describe the social interaction that takes place when peoplemove from conflict to dialogue. A qualitative case study of a nature conservation issue inÖstra Vätterbranterna, an area east of Lake Vättern, is presented.
Munksjökajen : Stadsplanering i Jönköping
Munksjökajen is an old industrial estate on the western shore of Munksjön in Jönköping. The purpose of this thesis is to develop Munksjökajen in accordance with the program for Jönköping?s future development ? Stadsbyggnadsvisionen ? drawn up by the city council.Munksjökajens relations to the surrounding areas have been investigated as well as the need for public transport and possibilities for commercial, municipal and private businesses to operate in the area.The final proposal has a relatively high degree of preserved industrial buildings. New buildings vary in shape and expression in order to create an interesting and diverse environment. The proximity to the lake adds character to the neighbourhood and the water is accentuated by the integration of it in the area..
Andraspråksutveckling i den mångkulturella förskolan
This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.
Tillväxtmönster och åldersstrukturer hos opåverkade bestånd av strömlevande Arktisk harr i Sibirien :
It is hard to find streaming waters where humans haven?t affected the fish populations or the
running water it self. In many streams the fish populations are over harvested and this results
in a lack of older and larger fish. This is also the situation for many populations of Grayling
(Thymallus spp.). To be able to develop management plans and to perform actions that
improve the situation for the grayling, it is therefore crucial to know what natural, by humans
unaffected populations look like.
Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet
This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .
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.
Igensättning av långsamfilter i Östby vattenverk i Kramfors : studie av påverkande faktorer
Östby waterworks in the community of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters which has led to their closing and this has influenced the water quality negatively.The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it reaches the outdoors placed slow sand filters.

Förutsättningar för jökellopp vid Fox Glacier, Nya Zeeland
A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. This is well known to happen atthe near by Franz Josef Glacier which has similar settings to Fox Glacier, but sparse previous researchon the subject indicates different results of whether jökulhlaups are present or not by Fox Glacier. Thisthesis therefore aims to study the conditions for jökulhlaups at the glacier. This is done by remotesensing and field observations of the sandur in the Fox Glacier Valley, qualitative interviews andliterature studies with a comparison with Franz Josef Glacier.
