Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

Pilotprojekt Drevfjällen, vägen till en hållbar regional utveckling?

Identifiering av lek- och övervintringsområden för lax (Salmo salar) och öring (Salmo trutta) i Klarälven

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

Väneramplitud ? Lönsamhet? : Kvalitativ studie av åtgärder, genomförda för att reducera risker och kostnadspåföljder av en förändrad vattenregim

Tappningsstrategin för Vänern ändrades i ett beslut från Länsstyrelsen i Västra Götalands län och Vattenfall AB, på uppdrag av regeringen år 2008. Detta gjordes för att minska risken för översvämningar i Vänern.  Åtgärden var föreslagen av Klimat- och sårbarhetsutredningen, som försökt utreda konsekvenser av klimatförändringar för Vänern i ett framtida förändrat klimat. I utredningen används en metod för att mäta kostnader. Metoden är en kostnads-nytto-analys (Cost-Benefit-Analysis; CBA) som användes för att utvärdera bland annat Vänern med omnejd. Enligt denna uppsats saknas det värdering för naturmiljö och sociala faktorer i denna utredning.

Byggnadsminnesförklaring : ett långsiktig hållbart skydd?

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

Hållbar utveckling i ämnet biologi : En kvalitativ studie om hur grundskolelärare i årskurs 4-6 arbetar med hållbar utveckling.

Denna studie grundar sig på hur lärare tolkar hållbar utveckling i ämnet biologi. Syftet är att undersöka på vilka grunder lärarna väljer arbetssätt och ämnesinnehåll. Lärarna som intervjuas är verksamma i årskurs 4-6. Intervjuerna är semi-strukturerade vilket betyder att teman behandlas utifrån en given intervjuguide, frågorna ställs därför inte med någon förutbestämd ordning. De lärare som ingår i studien är behöriga i ämnet biologi och urvalsprocessen grundar sig i ett bekvämlighetsurval.

Analys av vävnadsprover med endimensionell elektrofores

The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.

The project description is to draw an extension or annex to the existing Nationalmuseum building from 1866.The annex is designed to complement Nationalmusems activities and contain internal and public functions. Artentering the building must not be crossed by public visitors. Art and staff must be able to seamlessly move betweenthe extension and the main building. The new building includes a public study room for scholars working withthe collection of art on paper, workshops, conservation studios, art spaces and warehouses. Additionally, theannex is designed to host a large number of office spaces.With the renovation of Nationalmuseum they intend to open up the today built in south atrium.

Den strävsamma bonden och andra berättelser. En diskursiv studie av ska?nska hembygdsfo?reningars historiebruk.

The subject for this thesis is to examine the portrayal of the local farmer in four different museums in Scania. The purpose is to examine these two questions: 1. Which narrative and museal strategies are used in the portrayal of the local farmer by the local history societies? 2. How do the actors of the local societies relate to the living conditions and hierarchies of the rural society of Scania? The source material consists of guided tours and text material from the museums. The theoretical fields consists of history culture, use of history, historical narrative, museology and rural science act as our theoretical fields. Peter Aronsson, Anna Eskilsson and Maria Bjo?rkroth act as our main theoretical framework. Our research presents two central discourses in the portrayal of the local farmer.

Utvärdering av lockmedel för marklevande predatorer under midvintermånader i Norrbottens inland

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.

Möjliga av världar  idén om kvinnan i två kvinnors feministiska utopier : en idéhistorisk studie av Christine de Pizans The City of the Ladies och Charlotte Perkins Gilmans Herland

This thesis highlights starting points underlying the notions of two feminist utopians, Christine de Pizan and Charlotte Perkins Gilman. In approaching their texts, it focuses on the notions central to understand their writings. These would be historical, social, and cultural contexts. Defining concepts as utopian in its varying forms and feminism has been of significance. A feministic approach grounded in Simone de Beauvoirs philosophical phenomenology in the study of feministic utopia's visibility, has contributed to the understanding of the power structures to which women are tethered. In order to understand the way women are presented, it has become obvious that The Book of the City of Ladies and Herland are literary works that are related not only by their authors? background and personality but by the society in which they lived. Through their engagement in the contemporary intellectual debate on all social planes, both authors contributed to shifting the focus of their own contemporary notions of a woman to the notion of a woman equal to men. Woman, in Christine de Pizans utopia, is given specific properties and through themes of issues given meaning. She is not free in the sense that Simone de Beauvoir says.  She has a broader repertoire than was historically assigned, but her freedom is not arbitrary, contingent, and temporary and judged by her actions.

Sverige och Art- och Habitatdirektivet - i samförstånd eller avvikande : En studie om reglerande dokuments roll i implementeringsprocessen

Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.

Selånger deltapark : Sundsvalls nya stadspark - en vision

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.
