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..

Gränsöverskridande och samhällets förfall. Om det sublimas ursprung och relevans för samtiden

The free choice of upper secondary school?A study of the meaning of the information channels for the choice of upper secondary schoolAuthors: David Fridner & Rikard ZeilonMentor: Ingela WadbringQuestionnaire studyDate: 2008-08-11AbstractThe choice of upper secondary school is a very important choice, both for the school and for the ninth grader. In Göteborg, the free choice of upper secondary school has generated several new information channels apart from the traditional counselor, daily news and the acquaintance. Today it is harder than ever to reach the pupil through the constant media noise and new forms of communication such as events appear. The fight for each pupil gets more and more important every term and it has now become real big business.Today?s youth is imprinted by a growing individuality and everyone knows that equableness is something very important.

Vart är naturen i skärgården på väg? : skogshistoria på Ängsön-Marskär i Stockholms södra skärgård

The following thesis is a study of the forest history on the island of Ängsön-Marskär concentrating on the last three hundred years. The island is located in the administrative province of Stockholm, the local community of Haninge and it is situated approximately seven kilometres east of the island Ornö in the south of the Stockholm archipelago. The questions this thesis attempts to answer are: How where the natural resources on Ängsön-Marskär used through the centuries? How has the state of the forests developed since the 16th century? How will the nature develop onwards? The thesis is based on archival sources for Ängsön-Marskär and the surrounding areas. A field study was conducted where the entire island was investigated using an objective forest inventory method. The first map material existing over Ängsön-Marskär is from the year 1711.

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.

De Svenska dagstidningarna och dess relation till de Svenska emigranterna till Amerika mellan 1901-1904 : -En argumentationsanalys om Svenska dagstidningars åsikter om den svenska emigrationen, med inslag av nationalism.

The Swedish emigrants, in 1901-1904, were displeased with their home country, so they moved to America with hope to find a better life. Even though they were displeased they still had a great love for their home country and tried to either create a ?new Sweden? (the Swedish-Americans), or they traveled back to their families, hopefully with savings big enough to buy their own home. Sweden did not have a homestead act like the Americans did, which probably is the biggest reason to the emigration. There was also the question of each individual?s right to vote.

Den svenska kupongbeskattningen av utländska fondbolag och dess förenlighet med EU-rätten : Bör det svenska regelverket förändras

AbstractThe purpose of this thesis has been to investigate if the Swedish legislation concerning taxation of dividends to foreign investment funds is in violation to EU law. Furthermore, the thesis will analyze if the Fondskatteutredningens suggestions to changes in the current legislation is appropriate to the purpose it tries to obtain.Today there is a difference in the taxation of dividends paid to Swedish investment funds and foreign investment funds. Dividends paid to foreign investment funds is being taxed in accordance with the Coupon Tax Act (1970:624), in which no deduction of the tax is possible. Swedish investment funds on the other hand have the possibility to deduct as much of the received dividends that they have given in dividends to its shareholders.The difference in the taxation between investment funds because of origin has been reviewed by both Swedish court and by the European Court of Justice. It has in these cases been up to the courts to review if a difference in taxation of dividends could constitute a violation of the free movement.

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.

Förutsättningar för återintroduktion av stora gräsätare i Sverige

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

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.

Musik och kunskapsskillnader : -En studie om musiklärares upplevelser kring kunskapsskillnader inom musiken

ABSTRACTMusic and differences in knowledge ? a study of music teachers experiences with differences in musical knowledge. The purpose of this paper is to, out of a music teacher?s perspective, see if the differences in music abilities between 7th grade students are at all, or in some ways connected to the previous schools they?ve attended. I will also research in what areas, in the subject of music, students are differing more, as well as less, in their knowledge. The analysis is based on interviews with six 7th grade music teachers working in the Swedish nine-year compulsory school system.

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.
