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.

This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.

This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.

The aim of this thesis is to investigate how purchasingmanagers in bookshops and public librarians reason withregards to their selection of fiction literature. Nineinterviews have been conducted in this qualitative studymade in the spring of 2013; four librarians, four bookmerchants, as well as a market director of a major chain ofbookstores. Our focus has been particularly directed toascertaining what influence the cultural-political mission oflibraries have had on the process of selection, as well as theextent to which factors such as demand and quality play apart in both organizations. We have been interested inseeing how libraries and bookstores compare with regards tothese factors, because of obvious differences in their goalsand purposes. Librarians see both the benefits and flaws intheir way of working, as well as in the way in whichbookstores conduct their business, and vice versa, that theyare often successful in cooperating, like when arrangingvisits from authors etc.

In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.

The competition amongst companies is getting tougher and the economic markets are getting even bigger with new products and businesses. One way for companies to differentiate themselves from the competitors is through packaging design. If the merchandise is to send a reliable and solid message to consumers, the attributes of the packaging must be consistent and uniform. If the different attributes are not coherent, the message loses credibility towards the consumer. Through the sent messages, the pack signals the products? expected quality and price.This paper includes two studies, in which the main objective is to discover and build understanding about Swedish consumers? perception of a product?s price depending on the pack?s design.

SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

The progress of chronic disorders such as heart failure and chronic obstructive pulmonary disease affects various aspects of life. They have an deep impact on patients´experience of health and wellbeing and their functional qualities and quality of life. Several studies have in an extensive way described heart failure and chronic obstructive pulmonary disease in its own domain but few qualitative studies consider coexistence of the disorders from a caring science perspective. The aim was to describe the meaning of living with heart failure and chronic obstructive pulmonary disease from a lifeworld perspective. With a phenomenological and reflecting lifeworld approach it´s possible to describe eight patients daily experiences of living with severe and chronic disorders from their own narratives.

The thesis contains mainly personal experiences relating to classical piano improvisation, based on the CD record Härlig är jorden, Piano improvisations in Various Classical Styles. Sex classics: Mozart, Stravinsky, Bartók, Chopin, Debussy and Liszt play the main roles in that record.The idea is (apart from aiming at stimulationg the styles as faithfully as possible) to look at the various classical styles as different musical rooms created by the composers for us to enter and use. It is also a personal pedagogical goal to structure my ideas, including formulating the strongest possible requirements on the quality of my improvisations. A leading theme manifesting itself in different quises (depending on the style used) is not only a means for improving quality further. The audience has shown a great interest in this form.

The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.
