Thinning is the partial removal of trees in a forest stand prior to final harvest. The term can be divided in pre-commercial thinning where little if any volume is removed from the stand and commercial thinning where removals are intended to provide a positive economic result. From a silvicultural point of view, the goal of thinning is to enhance future crop tree quality by removing low-quality stems and providing sufficient space for the accelerated development of retained ones (Huuskonen & Hynynen, 2006). The goals of this study was to see if commercial thinning could positively affect the short and medium term timber supply (MTTS) in the Interior regions of British Columbia (BC), and whether or not Scandinavian forestry practices could be adopted in the BC context. The mountain pine beetle (Dendroctonus ponderosae Hopkins) has created significant forest planning problems in BC. The annual allowable cut (AAC) was raised to capture beetle-killed timber while still merchantable.

The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.

This essay discusses the legal and economic functions of the trademark and furthermore the degeneration of trademarks. These two concepts are strongly connected as the primary function of the trademark is the ability to separate the proprietor of the trademark?s product from the competitors´ products. The ability to separate is the basic condition for receiving legal protection. Through degeneration the trademark loses this ability to separate the product and becomes a generic term for the category of the product.

The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost. The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating. Which system to choose largely depends on how the own work is valued.

I denna studie undersöks hur införandet av jobbskatteavdraget 2007 och de två utbyggnaderna 2008-2009 påverkade arbetsmarknaden i form av sysselsättning, arbetslöshet, långtidsarbetslöshet och sysselsättning i åldersgruppen 55-64 år. Med utgångspunkt från en tillämpning av konsumtionsteorin, med arbetsutbudet i fokus, så görs en difference-in-differences analys av reformens tre första år i jämförelse med tre år innan dess införande. Resultaten visar att införandet av jobbskatteavdraget har haft en positiv effekt på arbetsmarknaden i form av en större andel avbefolkningen i arbete, medan ytterliggare steg av jobbskatteavdraget ger estimat som tyder på att effekten blir en minskad aktivitet på arbetsmarknaden..

The purpose of this paper is to study how Swedish CFOs perceive that the requirement for companies to issue quarterly reports affect business operations in the company. The fact that it is regulations on the Stockholm Stock Exchange, and not the law, that requires companies to issue quarterly reports makes Sweden unique in Europe. The paper is based on interviews with CFOs from 32 companies quoted on the Stockholm Stock Exchange. The major finding in the study is that a majority of the CFOs perceive that the pressure for short term results, created by quarterly reports, affect their work and the investment decisions made in the company. Also CFOs feel that the market over interprets the information given in quarterly reports.

THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.

The purpose of this study was to illustrate how cuts as a result of the economic crisis in 2008-2013 affected the newcomers' situation and the possibilities to reach the requirements for knowledge, based on the area manager, principals' and teachers' perspectives.The material we used for the study was made up of semi-structured interviews. We interviewed a psychologist, an area manager, principals and teachers. Most of the interviews were face to face and were recorded on a Dictaphone which we later transcribed and analyzed. During the process, we focused on the following aspects: acceptance and introduction support for new pupils, local opportunities and work material opportunities, school organization and employment structure, and reaction in the form of protests and demonstrations on restructuring the affected schools as a result of the cuts.The result that has emerged is that the teachers' main problem was the large increase in workload. The supervisors took no account whatsoever of protests and demonstrations organized in the affected area.

During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.

Generative artificial intelligence (AI) has rapidly gained traction in the education sector, with tools such as ChatGPT often highlighted as potential support in teachers? daily work. At the same time, the technology raises important questions about how its use should be organized and what responsibilities school leaders hold. The aim of this study is to deepen the understanding of how generative AI is implemented in school organizations, focusing on the strategic work of school leaders and how this is experienced by teachers. The study is based on a qualitative study, comprising interviews with 14 school leaders and teachers in a county in western Sweden.

The aim of this study was to reach a better understanding of voluntary work and its possible influence on the work role. Based on a phenomenological approach, five voluntary workers from the leisure field were interviewed. The interpretation of the empirical data was based on the Humanistic psychology and its theories about personality, self-realization, motivation and emotion. The results show that the motive behind the voluntary engagement varied amongst the participants and all of them stated more than one motive. However, social motives, wanting to learn more and develop their skills and also wanting to help others, were the most frequent motives among the participants. In the light of the theoretical background for this study, these motives can be understood as being due to the need of self-realization and appreciation from others, and also a wish to reach an ideal self.
