Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

Välkommen in i värmen! : En netnografisk studie över hur IKEA skapar, upprätthåller och utvecklar sina relationer i det digitala medielandskapet

Social media has meant that organizations can engage in dialogue with their audience without journalistic intermediaries. PR 2.0 is a term that defines the new way for organizations to work with public relations in the new media landscape. The aim of our study is to examine how IKEA uses social media to create, maintain and develop their relationships. Furthermore, great interest is directed to the concept profile. This essay will examine how the stated profile IKEA has pervades the work on social media.

Effekt av löpmagsförskjutning på mjölkproduktion, hälsa och utslagning

In this thesis we propose a conceptual plan for thedevelopment of an Agroforestry Training Centre (ATC)in Musoma, Tanzania. The aim is to make a proposalto support peasant education in agroforestry. How canan ATC in Musoma be developed into a stimulatingand educational park suitable for teaching agroforestrymethods to peasant farmers and other potential users?To answer that a field study was conducted to investigatehow our client Vi Agroforestry Programme (Vi) and thetarget groups of the client can benefit from the site.The thesis begins with a short explanation of thecontext, in which the ATC plays a part followed by amethodology chapter. Next are three chapters presentedwhich introduce the reader to the research conductedbefore starting the proposal, these include: results ofliterature studies, study of precedents, and results of fieldstudy.

Marina visioner : nya idéer för småbåtshamnen i ljuset av utveckling, urbanisering och klimatförändring; tillämpat i Rydebäck.

New dwellings and commercial buildings in coastal regions has for some time now been a focal point. Old industrial harbours are regenerated into modern living areas with a recreational purpose. In Sweden the marina has not taken part in this development, thus remained in the monotony and large-scale structures of modernism. This graduation thesis looks upon the marina from a landscape architects point of view, where the marina foremost is a social venue. By revealing and discussing the development of the marina, its design and environmental consequence theories of the marinas future is presented. These theories are later tested upon the costal village of Rydebäck, south of Helsingborg. The thesis is structured in three parts: marina knowledge, proposal and resources. In the first part the historical development of the marina from prehistory time to now is discussed.

Stadsodling : möjligheter och begränsningar

Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.

Det enskilda trädet som meningsbärare : erfarenheter av två trädplanteringsprojekt i Helsingborg

Individual trees can act as carriers of meaning. When a person attributes deep meanings to a specific tree, a relationship between the person and the tree is created. To avoid conflicts between users and planners, increased awareness is required of how important individual trees may be to a person. The objective of this study was to elucidate persons? relationships with individual urban trees.

Hard Decisons, Soft Laws : Exploring the authority and the political impact of soft law in international law

The question of whether there is soft law in international law has been as much the subject of contemporary debate as whether or not there is private legal authority in the international society. The legal boundaries seem to be blurred by the process of globalisation and the recent shift in international law. The traditional definition of international law has been outdated as new forms of treaties has introduced new subject of law to the judicial arena. At the same time a supplementary map of law has been added to the cartography of international law, soft law. These correlating processes have comprehensive political and legal consequences at both the international and national levels.

Förändring av radiocesiumtillståndet i jordbruksgrödor i Gävleborgs, Västmanlands och Uppsala län efter Tjernobylolyckan samt en fallstudie med stallbalansberäkningar på en mjölkgård :

Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely. When radiocaesium decays to a stable end product ionizing radiation is emitted, which can cause cancer in humans that has been exposed to a high radiation dose. Radiocaesium behaves like potassium and is easily taken up into biological systems.

Trädföryngring i låga gropar uppkomna vid brand i boreal naturskog :

This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees. In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.

Kampen om klasskampen : en undersökning av de politiska maktförhållandena inom Grov 84:an i Västervik mellan 1925-1930

After being excluded from the Swedish Social Democrat party in 1917, the Revolutionary Socialists founded the Social Democrat Left Party. From this point onwards, the Social Democratic hegemony and dominant position within the Swedish workers movement and political landscape was challenged. This thesis aims to investigate the power struggles between these two parties, the Revolutionary Socialists and the Social Democrats, and their desire to influence control of the unions. Taking cues from earlier research calling for a more localized look at this struggle, this thesis turns to a case study of union matters of the the Factory Workers Union Local 84, at Västerviks Tändsticksfabrik, a match manufacturer and largest employer in the Swedish coastal town of Västervik from 1925 to 1930. Organizational material including meeting protocols, annual reports and member registration lists from the local political parties, cooperative union organizations (VFS) and Local 84 serve as secondary data sources.

Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.

Methane production from dairy cows : relations between enteric production and production from faeces and urine

Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.

Urban agriculture/Agricultural urbanity : om stadsodling, urban och peri-urban agrikultur, för en mindre klimatbelastande och energikrävande matproduktion

Syftet med arbetet är att studera UPA (urban and peri-urban agriculture), samt relaterade strategier för en alternativ livsmedelsproduktion. Arbetet strävar efter att samla kunskaper och koppla samman frågor kring dagens livsmedelssystem, hur våra städer är uppbyggda, och den alltjämt högaktuella klimatfrågan. Arbetet omfattar diskussioner kring stadsbyggande, transporter och mobilitet, avfallshantering, och en mer lokaliserad livsmedelsproduktion. Målet är att skapa ett kunskapsunderlag för framtida integrerad stadsplanering och gestaltning. De förslag och lösningar som förs fram är tänkta att passa i en svensk kontext. Planering och stadsbyggnad berörs på många sätt av beroendet av fossil energi.

Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
