Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie
Running water-pathways have played an important roll in Sweden and frequently been
manipulated. One profound change was made during the period of logging when
streams were cleared from obstacles as big boulders, sharp bends and side-streams.
Dams and different constructions gave control of the stream water and the streams
became channel-like with a homogen structure. This interference gave problems for
many fish populations and resulted in a shortage of feeding habitat, over-wintering
habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural
temperature fluctuations. Many of these historical changes of the watersheds are now
subjects for Restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.
Bevarande av parker, trädgårdar och landskap
Abstract In order to work with historical sites, there must be an understanding of the complexity around the preservation of parks, gardens and landscapes and the approach to be used in the rebuilding and renewal. These issues are an important starting point of this essay. Historical environments give us as individuals an insight in who we are and from where we come, which is an important part of our need of identity as human beings. Without them, our roots in the past will be non-existent. The importance of this support base lies not only in the garden conservation, but also in the picture of developments, which we have through of as time mirrors of our living environment.
Rörlig eller fast bolåneränta : resonemangen hos låntagare
The purpose of this thesis is to describe property definition and special boundary demarcation and to analyze the differences between the two cadastral procedures. Property boundaries, especially unlawfully determined boundaries created through unofficial parcelling, can create conflicts between landowners and make it diffi-cult to know which land that a property contains of. It is possible to clarify the boundary conditions through a property definition or through a special boundary demarcation re-establish boundary marks.The methods used are: (1) A literature review to collect background information, (2) A case study to summarize court cases and (3) A questionnaire study to collect opinions from cadastral surveyors.The result is summarized in two comparisons. Firstly between Restoration of landmark and special boundary demarcation (which replaced Restoration of landmark in a legislative change in 2010), which demonstrated that the change in the law is considered positive because special boundary demarcation gives a legal effect on the boundaries. Secondly between property definition and special boundary demarcation which demonstrated that the two procedures are similar to each other.
Spawning site selection of brown trout in habitat restored streams
During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in Restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.
Stadsdelsförnyelse på Öster i Gävle : En analys av fysiska faktorer för en bättre boendemiljö
Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive Restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive Restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.
Fejans vandrarhem ? En studie om isolering och uppvärmningsalternativ
During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in Restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
CARL BILDTS BEMÖTANDE AV JÄVSANKLAGELSER PÅ TRE OLIKA MEDIALA ARENOR ? EN RETORIKANALYS
In July 2011 the journalists Martin Schibbye and Johan Persson are arrested in Ethiopia when on a mission to report the activities of the oil exploration company Lundin Petroleum. Following a trial, closely observed by media, the two journalists are convicted to a prison sentence of eleven years. The Swedish Minister of Foreign Affairs, Mr. Carl Bildt, is now to act on their behalf to preserve their rights as Swedish citizens. However, doubts are raised as to whether Bildt has a conflict of interest because of his former engagements as a board member in Lundin Petroleum.
Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie
Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.
Förändringar i vegetationens sammansättning efter en våtmarksrestaurering : Changes in the vegetation composition after a wetlandrestoration
The loss of such great wetlands, which has arose in Sweden the last decades, has created a situation that threats both the function and the biological diversity within the wetlands. Many ecological niches can be found in the wetlands and it is one of the habitats where most different species exist. In the 17th Century people started to ditch damp environments, such as bogs, to create a productive cultivated ground. Further ditches were made when the forestry gave large economical profits. The wetlands were impoverished from both groundwater and nourishment, and this led to a great loss of species.In a corporation with WWF and Skogsstyrelsen in Arvika, the University of Karlstad has participated in the Laskerudproject, a hydrological Restoration-project in a forest landscape.

Försvarsenhetens arkiv : Examensarbete på länsstyrelsen i Södermanlands län
The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..
Kyrkorestaurering ? problematiken kring kulturhistoriska värden
This thesis handles the problems regarding different value aspects which are applied during Restoration and renovation of churches. The curator?s aspects along with the interests regarding change that exists today, is often integrated and is therefore affecting the final results. The thesis aims to discuss the different perspectives and to look at the different values the room possesses. Furthermore, the historical aspects are discussed along with possible strategies to increase a positive outcome of Restorations and how to integrate churches to the modern standards in terms of use and allowing them to be a part of a living cultural heritage.Church buildings have historically speaking always had a significant meaning to people, independent of religious belief.
Bottensubstratets inverkan på föryngring av Flodpärlmussla
The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.
