Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.

This thesis focuseses on archives and availability. The general public seem to have trouble finding their way tothe actual archives even though most archival institutions are easily accessed and provide interesting material.Maybe it is because archives are generally not as well known as other institutions within the ALM-area, eventhough the need to know ones history and identity is considered mainstream. Whether or not history takes off atthe archives is a complex question to answer. Archives, however, certanly contribute to our ideas of earlier timesand the concept of history.I have examined what archives do to make these contributions known to the general public and to whatextent they make their material avaliable. I have also looked into archival pedagogy since it is often connected toavaliability.

How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and  about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers  a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.

The starting point for this thesis has been the great process of change that Swedish municipalities now arefacing due to the political directive of offering full-time employment to all part-time employees. The aimof the research is to create a decision support model for Swedish municipalities, which simultaneouslyintroduce the offer of full-time employment and an internal personnel pool. The factors that mayinfluence the personnel?s choice of employment level and the quality of the outcome, thus the financial result,are we also aiming at explaining. The empirical observations were found through secondary data as well asobservations from the municipality of Göteborgs Stad.

Recently, there have been intense discussions about the humanities and their role in society. Internationally, as well as in a Swedish context, the humanities have been regarded to be in a state of crisis. However, these discussions usually demonstrate a lack of historical perspectives based on thorough empirical research. The notion of a crisis needs to be historicized.In this study, a case is being examined where the relationship between science and society was renegotiated. In the context of World War II, a discourse has been identified in a borderland between science and politics through an analysis of Swedish journals and anthologies during the time period 1937-1947.

The purpose of this project is to examine the development of the upper secondary school physics course and from this get a better understanding why the course is organized the way it is today. The timeless argument for studying science in school will begin this essay. After that the reader will be aware of when important discoveries in physics were made. Then school history is presented. In this part we are told when the first school started in Sweden, but the focus lies on the upper secondary school and the physics course.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

Recent studies show that manufacturing companies to a larger extent use historical cost accounting in their internal accounts, at the expense of calculated costs. The explanation behind this is claimed to be that firms are subject to careful scrutiny by the stock market. Consequently, top management stresses the need of evaluating all parts of the firm from external accounting. However, lower management levels express a general concern that the incentive to invest in machines will decrease. This master thesis aims to investigate whether or not there is an objective reason behind this concern.

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

The purpose of this research is to examine some historical aspects of Robert Putnam?s thesisabout voluntary associations and social capital. According to a micro perspective theory ofsocial capital the trust and reciprocity required and created by associations is important toexplain the disparity between institutional performance and socioeconomic development ofsocieties. The social patterns governing this therefore set a precedent for the future. Using themutual sickness benefit societies in Sweden as variable for voluntary associations around1884, the essay discusses the possible links between social capital, associations and long termeconomic development.

This thesis concerns the term contemporary history and its role in landscape architecture. Today?s contemporary history is defined as the planning and architecture connected to the 60s and 70s, in Sweden carried out as a large scale planning project called ?Miljonprogrammet?, which set out to build one million new residences in ten years. Initially, the term contemporary history and its complex of problem are examined. To deepen the picture of today?s situation, a historical review has been made, starting in early 1900s ending in 2000s concerning how different planning and architectural influences has varied through the years.

Building on the concept of constructive iconoclasm as a creational force of iconicity, this thesis examines how the contemporary iconoclastic discourse is related to artistic process. Studies have shown that the performative act of destroying art that is an historical phenomenon is highly present within the contemporary art discourse today. Due to the many dimensions of contemporary art, the ways in which iconoclastic deeds appear may differ from the historical narrative. While iconoclasm and iconicity are being reciprocal processes that can only exist in relation to each other and their context, there are signs that the destructive act itself is being recontextualized by contemporary artists. Guided by the framework of Norman Fairclough?s critical discourse analysis, the thesis examines the processes of conceptual and constructive art destruction by analyzing the discourses of two case studies situated in the contemporary art market.

The aims of the following project has beento make a proposition how to create aspecific kind of transformer. Thefollowing report evaluates the differentimportant variables and contains asuggestion for a possible design. Intheory it's an ordinary transformer that'ssuppose to transform electrical effect toa high voltage line. The design of thetransformer is using an already existingcurrent transformer design and is adjustedto work for it's specific purpose. Theproject also contains the developing of atransformer simulation model that will beused to evaluate and optimize thedimensions of the resulting transformer..

The purpose of this study is to evaluate the relation between certain chosen fundamental factors (emission trading rights, hydrological balance, interaction with continental Europe, fuel prices) and the spot price at Nord Pool. Particular focus has been put on the trade with emission rights since it is only now their actual impact on electricity prices can be studied. The relationships are measured with regression analysis which includes both R2 and the simulation possibilities of ARX models. The studied period covers 2008 and 2009 with partly daily data and partly weekly data. Owing to the expected higher importance of the fundamentals during the winter months the winter 2008/2009 has been studied separately.
