Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?
The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.
Mellan Askim och Angered En kvantitativ undersökning av mediers framställning av individer i socio-ekonomiskt olika boendeområden.
Authors: Fanny Edstam & Joacim KettilTitle: Between Askim and Angered. A quantitative research of media's presentation of individuals in different socio-economic residential areas.Level: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 41Gothenburg is a city that struggles with the issues of segregation. Residential areas like Askim are poorly integrated and areas like Angered have a high amount of immigrated inhabitants. Our hypothesis, with this in mind, is that one can assume media reports from different socio economic residential areas in different ways. The assumed difference in reporting can have aneffect in the readers beliefs that an area can be better or worse than it actually is.
Uttryck i sten : En studie av röjningsrösen, stensträngar och husgrundsterrasser under mellersta järnålder i Uppland
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.
Kvävestatus och risk för nitrifikation i två avverkade skogsområden i Halland
Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.
Hyggesbränning på Orsa besparingsskog - en studie på tillväxt och föryngring,15år efter etablering
The main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.
Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård
Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..
Södras gröna skogsbruksplaner ur ett landskapsperspektiv :
The aim of the "Green forest management plans" is to help forest owners to reach the
environmental goal of the forestry act. But are they able to do that? Is it possible to plan preservation of species on single estates? How do single-estate-plans differ from a landscape analysis and how can the landscape approach be used in operative planning? This work was initiated to give an answer to these questions.
This study was made in a landscape of 4200 ha in Östergötland county, south-eastern Sweden. A lanscape analysis was made and then compared to the Green forest management plans in the same area. The nature conservation areas (areas that were set aside to be managed with environmenatl goals) differed quite a lot between the two alternatives.
Castration coverage and attitudes towards a castration program in Lilongwe, Malawi
The aim of this study was to measure the castration coverage and the attitudes among people towards castration in an area in Lilongwe, the capital of Malawi, where a castration program has been running for a few years. Another aim was to review the literature to examine the link between castration coverage and rabies prevalence. Two areas (Area 25 and Area 23) in Lilongwe were studied through standardized household interviews. In Area 25, a non-governmental organization had been castrating dogs weekly to twice weekly for free for 3 years. In Area 23, no official organization had done castrations, and this area therefore acted as a control in the study.
Bullerreduktion av hytt på Volvodumprar : Undersökning, mätning och analys
Too high levels of noise lead to various health problems and cost society billions of SEK peryear. In this thesis we have examined a model of the A40E articulated hauler at VolvoConstruction Equipment in Braås. We have tried to reduce cabin noise in an articulated hauler,while also providing a way on how to proceed with a machine when the cabin does not measureup to the sound requirement. The best way to find leaks were with a reference source of model4205 and its speaker HP 1001 from Brüel & Kjaer in the cab and then walk around and listen towhere the reference source was more prominent. In this way, we found that the edges and theplugs were sensitive areas.
Biologisk mångfald i små grönområden : Inventering av insekter och fåglar i bebyggda områden i Solna kommun
All over the world the urbanisation increases at the expense of green areas. Many plants and animals are endangered today because their habitats gets smaller or disappear. The green areas that are left in city centres and suburbs are often small and surrounded by roads and buildings. Despite this, several studies have shown that these small green areas may house large biological diversity.This project aims to study the biological diversity in small green patches in residential areas. The study has been carried out in Råsunda in Solna municipality (Stockholm county) during the period May?July 2006.Three equivalent areas (5000?10 000 m2) with quite many old oaks were chosen for the study and inventoried for birds and saproxylic insects.

Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro
The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

Rural development in Southeast Sweden- three different views and their consequences for the agrarian landscapeThis paper deals with the future for the rural areas of the southeast province of Östergötland, Sweden. The aim is to unveil, analyse and compare different views on rural development and their consequences for the agrarian landscape. Three views are considered, namely that of the different levels of Governments and their departments, that of the farmers and landowners and, finaly, that of the inhabitants of the rural areas.Differences in the views upon rural development is reflected in differences in the ways of thinking of landscapes. Is the open, and actively cultivated, landscape the ideal for all? Who is to decide what needs or ought to be done to achieve certain desired values and/or goals ? and who pays for it? The one thing that is, and should be, clear from the beginning is that all development, whether positive or negative in an area, bears consequences for the landscape.
Tillgängligt landskap : spänger i naturmark
The title of this thesis is ?Accessible Landscape - boardwalks in nature areas?.
The main purpose of this thesis is to show how you can increase the accessibility for disabled people by constructing boardwalks in nature areas.
The platform for the thesis is a study of litterature on boardwalks, accessibility and disabilities. After defining these terms I made three excursions to three different locations in the south of Sweden. During the excursions I evaluated the boardwalks situated in each of the areas through preferences such as the construction of the boardwalk, its design and the accessibility.
After the excursions I interviewed managers of the areas I visited, and people working with disability questions in the municipalities where the excursions took place.
To know how to make a boardwalk accessible you need to have knowledge about certain concepts, rules and recommendations.
My thesis deals with aspects such as:
*Accessibility
*Disability
*Rules and recommendations when building boardwalks
*Real life - evaluation from the excursions and interviews with the
managers
The result shows that accessibility is a hot topic in Sweden and a lot
of improvement is being done with fi nancial support from the European
Union.
Svenska Akademiens Nobelbibliotek : en uppsats om Nobelbibliotekets inköpspolicy och förändringar inom inköpta språkområden sedan 1904
The essay is about the Nobel Library's investments in fiction, the change of certain linguisticareas since 1904 and the purchase policy of the Library. The paper contains an introductoryhistorical chapter, where I describe the history of the Swedish Academy, the life and willof Alfred Nobel and in conclusion a description of the Nobel library of the Swedish Academy.When writing this essay I have used a combined qualitative and quantitative method, meaningthat I have interviewed the librarians of the Nobel Library, studied the purchase catalogues,and kept statistics over the books.in different linguistic areas purchased since 1904 onwardwith an emphasize on years ending with "4". The outcome of this survey is that the purchaseof books within the different speech areas doesn't vary as much as first expected, and thatthere rises and falls within all the linguistic areas which could be further explored..
