With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

The aim of this paper is to highlight issues and potential problems regarding conservation inan exhibition situation. The thesis presents a case study from the Röhsska museum, inGothenburg, where an interior of painted tapestries was currently being conserved andrestored. The study includes general history about the painted tapestries, conservation historyand information about the current treatments.The painted tapestries originates from a former manor [sv: säteri] in Gothenburg calledHökälla and were donated to the Röhsska museum in 1916. The tapestries were a part of themuseum?s permanent exhibition until 1996, when it was dismounted and put in storage.

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this. Many companies feel forced to align their strategies to the environmental goals set by the community. Some of the emissions the companies? operations can be linked to business trips and it is therefore interesting to see how these can be reduced by using different performance measures.

Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.

The aim of this study is to analyze the justification of a financial incentive that rewards students who rapidly finish their studies within the language education ?Swedish for immigrants? (sfi). Thereby, we want to see what assumptions are made about the students, and relate this to experiences of the education at a local level. We applied a text analysis on a government bill about the incentive, which showed that the deficiencies in the education are said to be caused by the students? lack of effort.

Purpose/Aim: The aim of this study is to (1) analyze the amount of exposure disability sports get in Swedens biggest newspaper (Aftonbladet), (2) look at how Aftonbladet portraits disability sports and it?s athletes, and finally (3)  to see if there has occurred any change over time (during the last eight years). Material/Method: The first method used is a quantitative analysis to measure exposure.The second method is a quantitative content analysis which is used to analyze how disability sports are portrait.The third method is rhetorical and is also used to analyze how disability sports are portrayed. Main results: The study has shown that disability sports get very little exposure in Aftonbladet. The articles in the newspaper that cover disability sports are portrayed from a personal point of view without much focus on the athletes achievements regarding his or her sport.

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

This study addresses the issue of mergers between consulting firms. Previous research has shown that there are specific factors that determine the outcome of a merger and that success is more likely if companies are more similar. The purpose of the study is therefore to define relevant factors and understand when resemblance matter and under what conditions disparity may cause problems. Furthermore, the aim of the study is to find a pattern of which factors are more important in a successful merger. The problem of the study is addressed through a qualitative research approach and is conducted on six different mergers.

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

Background: Performance measurement as a management control tool has received considerable academic attention. As the number of inter-organisational relationships, such as customer-supplier relationships, increases, there is a new scope for performance measurement as a management control tool. In order for a company to assess the effectiveness of its supplier relationships it has to define, measure and evaluate variables that are critical for the success of the relationship. The role of management control, and thereby of performance measurement, has increasingly been discussed in theory. However, empirical research in this area is still somewhat limited.

Projekt har blivit en arbetsform som är vanlig i många branscher, i många organisa-tioner och för många olika uppgifter, och som dessutom ofta är det normala sättet att arbeta. Idag finns ett stort antal företagsspecifika och generella projektmodeller. Des-sa är vanligen normativa och definierar ofta faser, roller, beslutspunkter och doku-ment i ett idealiserat typprojekt. De är ofta tänkta för en viss kategori av projekt med vissa gemensamma särdrag, t.ex. likartade projektmål, genomförs i samma bransch eller har fokus på vissa aktörer.Undersökningen utgår från en modell som består av fem projektarketyper ? Pro-duktutvecklingsprojekt, Marknadsprojekt, Interna förändringsprojekt, Kundorder-projekt och Evenemangsprojekt ? som tillsammans på ett stiliserat sätt beskriver alla projekt som bedrivs som en del i en moderorganisations verksamhet.Undersökningen söker besvara om den undersökta modellen kan vara till nytta för ledningen av det Undersökningen är i sin helhet genomförd som en litteraturstudie.Undersökningens resultat tyder på att den domän som projektarketypmodellen be-skriver ? projekt inom yrkesmässiga organisationer och däri främst projektorientera-de företag ? utgör en naturligt avgränsad domän.

Assessing the outcome of corporate responsibility is often argued to be complicated due to long-term effects and qualitative aspects. Epstein (2008, p.261) establishes that: ?Though many think that sustainability is too difficult to measure, companies have found that unless the impacts are measured, they are commonly ignored in the resource allocation process?. Corporate responsibility is often referred to as a business case, i.e., that social and environmental concern add value to the business (Heikkurinen, 2010; Porter & van der Linde, 1995). Hence, for corporate responsibility to be a business case a strategy, corporate structure and systems, programmes and actions linked to performance measures need to be in place to assess the outcome; environmental, social as well as financial.

This thesis examines the effects of the Swedish school reforms that took place in the early 1990?s. Theories such as Principal-Agent, Stewardship and Lipsky?s street-level bureaucracy are discussed as well as New Public Management (NPM). These reforms were heavily influenced by NPM, causing an increased level of street-level bureaucracy, and according to Principal-Agent theory some outcomes could have been predicted.

The ability of dairy cows to survive and the economic importance of this have been in-creasing in dairy cattle breeding lately. Increased longevity contribute to an increased pro-portion of cows that produce milk in more productive lactations and reduces the replace-ment costs together with a good health and fertility. Unfortunately it is often argued that longevity has been decreasing due to a strong selection for production traits in dairy cattle.The aims of this study were to find correlations between different longevity evaluations and between different estimates on longevity and other traits in the Nordic Total Merit (NTM) breeding value. The aim was also to compare different traits for cows of two differ-ent longevity groups.The data were Predicted Breeding Values (PBV) from Nordic HOL and SR bulls and records from Holstein (HOL) and Swedish Red (SR) cows estimated by the Swedish Dairy Association.The three Swedish longevity indexes were very highly correlated (>0.89) and the corre-lations between the Swedish official longevity index and the five Nordic Cattle Genetic Evaluation (NAV) longevity indexes varied between 0.73-0.83.In the sire evaluation part, the traits most negatively correlated with longevity for HOL were dairyness, protein and fat index. In SR, milk, protein, and fat index only had slightly positive correlations with longevity.

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.
