Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel
Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management.
The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.
"Campinglivet med den obligatoriska stödbensölen" : En multimodal kritisk diskursanalys av reality-programmet Böda Camping med fokus på alkohol och klass
This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.
A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking
The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.
Tillämpning av naturvårdsavtal :
Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature.
The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.
?Tala nu om för fröken vad du kan? : en komparativ studie om fem lärares syn på bedömning i skolår 1-3
The evaluation and assessment of a pupil?s knowledge is today an important part of a teachers work. The function of the evaluations for younger pupils (grades 1-3) has assumed a more prominent role in the school system due to the introduction of written assessments as well as national testing in grade 3. One of the purposes of this research has been to find out the teacher?s opinions of the written assessment in grade 3.
Värdering för markåtkomst vid järnvägs- och motorvägsbyggnation : en fallstudie av intrångsvärdering i området mellan Örebro och Arboga
The purpose of this work has been to investigate if there are any differences in the valuation process at infringements when highway and railway are built.
The work has mainly been concentrated on the negotiation process in which The National Railway Department (Banverket) and The National Road Administration (Vägverket) try to get agreements with the land owners. The agreement includes compensation for infringement effects that affects the landowner?s property.
The National Road Department uses the road law (Väglagen) when a highway shall be built.
Skogens sociala v?rden. En j?mf?rande studie ?ver planeringen av kommun?gd skog
F?rt?tningen av st?der skapar en utmaning f?r bevarandet av de t?tortsn?ra skogarna. V?rden
som skapas av m?nniskans upplevelser i skogen kan sammanfattas i begreppet skogens sociala
v?rden, som visat sig ha en stor betydelse f?r folkh?lsan. D? m?nga kommuner ?ger t?tortsn?ra
skog, ?r det av intresse att studera hur de planerar f?r skogens sociala v?rden.
Betydelsen av taggbuskar, ljus och hävd vid föryngring av ek (Quercus robur)
Many species and hence biodiversity depend on old, large oaks (Quercus robur) with hollow trunks. The populations of oak-living organisms have to migrate to a nearby old oak in order to survive the death of the host. The oak district south of Linköping, Sweden, is unique in area and the number of old oaks. It is anyway doubtful whether regeneration of oak will secure future continuity. Oaks are light-demanding and thrive in open pastures.
Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor
Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. Detta lämnade stora ytor av Borneos skogar i ett undermåligt, sekundärt tillstånd. På grund av detta startades INIKEA projektet med syfte att rehabilitera skogar i regionen kring Tawau vid östkusten av delstaten Sabah i Malaysia. I denna studie undersökte jag resultatet av rehabiliteringsarbetet på krontaket i tre olika skogstyper genom att ta hemisfäriska foton med en digital systemkamera (DSLR).
Avskaffandet av revisionsplikten : En studie om vilka faktorer som påverkar små aktiebolags val att ha kvar revisionen
Background: With the removal of audit requirement for companies in Sweden from the first of november 2010, a lot of companies has chosen not to keep the audit requirement. So far 57 percent of the small companies has chosen to keep the audit, in spite of that they don´t need to which led us to the problem statement: Which are the factors that affect a small limited company to choose to keep the audit, in spite that now there is a possibility to choose not to use audit anymore?Purpose: The purpose of the essay is to examine why small limited companies choose to keep the audit, in spite that now there is a possibility to choose not to use audit?Method: This research founds itself in a qualitative study with a deductive research approach. We have been studying secondary data in books and articles and preformed 29 phone interviews with small ltd company owners in Sweden. The selection consisted of 14 companies with credit debts and 15 companies without credit debts.

En händelsestudie av reporäntans effekt på den svenska aktiemarknaden
Syftet är att undersöka om det finns möjlighet att uppnå överavkastning på den svenska aktiemarknaden genom att använda sig av information om förändringar av reporäntan. För att uppfylla vårt syfte utför vi en händelsestudie med en kvantitativ metod och en deduktiv ansats. Genom att studera nio branschindex och OMX index vid reporänteförändringar, undersöker vi om det föreligger någon skillnad dem emellan. Att en onormal avkastning kan uppnås kan statistiskt säkerställas för OMX index dag 1 efter en annonsering om en sänkning av reporäntan. Vid en höjning finner vi däremot inga bevis för en reaktion på marknaden.
Kvalitetsarbete i grotskotning
This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.
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.
Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion
Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.
