The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

In 1994 a new Forestry Act was accepted in Sweden. One of its aims was to raise the consideration for preservation of biodiversity. Since this happened over 15 years ago there is now an interest in analyzing if the law has been effective in its purpose. In this study methods suitable for analysis are being investigated. The study contents a pilot study of methods for five parameters that can validate if the law has been followed.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Introduction: Increased ill health in the workplace in terms of increased workload, stress and pressure from employers is common in Sweden today, which may lead to a future variety of medical conditions and disabilities. Aim: The aim of the present study was to describe what employees at companies in the health industry experienced as a health and illhealth on a workplace. Method: A qualitative approach was used in which the interviews were based on an interview guide. The method of analysis was thematic analysis in which three themes emerged. Results: Tree themes emerged; a social interaction with colleagues, good leadership, and access to health care and movement.

Patients who undergo surgery receive general anaesthesia or any form of conduction anaesthesia during the operation. For most people it is strange, unexpected and for many something completely new to be a patient and undergo surgery. Awake conduction anaesthetic patients? experiences from the intraoperative period were little studied. The purpose of this study was to examine awake conduction anaesthesia patients? experiences.

What psychologial processes are activated in experiencing mourning after a loss of a belovedperson? How is death described in other authors? novels and short stories compared to mine?This essay aims at analysing my two short stories The follower and The price for love fromdifferent aspects. I discuss the psychological realism and the spirituality using the method ofclose reading, interpreting and applying ideas of texts from other authors in my short stories.Death is a central phenomenon in both of my texts. Therefore I discuss death frompsychological and philosophical aspects in this essay. To get a philosophical frame of death Iturn to Jacques Derrida, Emmanuel Levinas and Martin Heidegger.

My study is focused on one organization with is Unicef, the organization that is workning on a UN mission. The mission is about children's rights and Unicef has brought children's actions since 1946.The purpose of this essay was to research whether the images can be used alone or as a complement to the text that the communication organizations use. By examining the way images are used, I hoped to be able to deduce the results of image use. I study if the effect out messages with only pictures will be more effective than the message in which the verbal mixed with the non-verbal.Theoretical part of this essay has a communication perspective. The essay is structure by tree elements, non-verbal communication, mass communication and intercultural communication.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

This thesis examines art exhibitions, literature events and music events in public libraries in Sweden. The aim is to study which event occurs most in the libraries in Sweden. I also examine who takes responsibility for the events, who the libraries engage, how much the events cost, and how often the libraries have the events. I also study Swedish cultural politics in purpose to see if the libraries follow the aims and directions decided by the Swedish government. One aim of the Swedish culture politic is to give every citizen in Sweden the same possibility to experience culture, no matter where they live.

Främmande trädslag har i modern tid intresserat skogsbruket i sin jakt på ökad produktion, minskad känslighet för skador, förbättrad anpassning med mera. Ett tidigare oprövat trädslag var banksianatallen (Pinus banksiana, Lamb.), en nordlig, välspridd, pionjär från Kanadas inland med en utpräglad etableringsstrategi för torra, nybrända sandjordar. Studiens övergripande syfte var att utvärdera utfallet från 22 år gamla försök av banksianatall och analysera banksianatallens odlingsvärde i norra Sverige genom att på fem lokaler jämföra överlevnad, tillväxt och skador med tall (Pinus sylvestris L.), contortatall (Pinus contorta var. latifolia Engelmann) och hybriden mellan contortatall och banksianatall. Ett ytterligare syfte var att utreda eventuella effekter av odlingslokalens temperatursumma och trädens latitudförflyttning från ursprungslatituden. I metoden har fältförsök använts där varje enskilt träd mätts och bedömts. Materialet var insamlat i naturbestånd i nordvästra Kanada från 12 provenienser med en latitudinell spridning av cirka fem breddgrader.

Forestry in Sweden is currently conducted in a manner aiming at equating the production objectives and the biodiversity. To ensure that biodiversity is maintained, patches that are considered to be valuable now or in the future is saved in final fellings. How the tree retention areas will grow into the future forest stands is yet unknown.The purpose of this study was to visualize how different scenarios of natural consideration taken at final felling will evolve in a long term perspective, for two rotation periods. Projections of the forest conditions were executed with the decision support system Heureka and its applications PlanStart and PlanWise. The information about the projected forests was then used for the visualizations which were created in the software Visual Nature Studio.

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.

The purpose of this study is to discuss various approaches to group work and the importance of different approaches in relation to group work in schools. The study also looks at the results of the children working in different groups and constellations.This study is based on what previous research, literature and the tree teachers say about the subject group work and group divisions. Issues: Is there any kind of group work that always works? Does the structure of the tasks have any effect on the outcome? Is there any good reason to choose the teamwork approach that? The method I chose is a qualitative study with a phenomenological approach to the analysis. Three teachers were interviewed; result is presented in themes and concludes with a brief summary.
