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.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

SammanfattningDenna uppsats undersöker möjligheten till självförvaltning i studentbostäder. Med rådande studentbostadsbrist i baktankarna är syftet med arbetet att bidra till en ökad produktion av studentbostäder i Sverige, med målet är att klarlägga studenters inställning till självförvaltning. Detta ska besvaras med hjälp av frågeställningarna som följer: Vad innebär självförvaltning?I vilken utsträckning kan en student hjälpa till med förvaltningen av bostadshuset?Hur stort är intresset för självförvaltning bland studenterna?Uppsatsen grundar sig på en litteraturstudie om självförvaltning, intervjuer med fastighetsförvaltare och slutligen en enkätstudie, som ska klarlägga studenters inställning till självförvaltning.Uppsatsen är en fördjupning av vad självförvaltning innebär. Begreppet är svårtolkat, men kan förklaras som ett underhållsarbete inom den egna fastigheten som utförs av de boende till en reducerad hyra.

Denna rapport ger en bild av vilka olika saker byggherrar i Sverigeanvänder sig av idag för att öka den sociala hållbarheten. De projektsom studerats är Bygga om Dialogen i Malmö, Älvstaden i Göteborg,Vivalla i Örebro och föreningen Byggemenskap.Genom att intervjua en person från varje område studeras likheteroch skillnader i hur man arbetat med den sociala hållbarheten vidbyggnation. I Malmö och Örebro studeras arbetet med att öka densociala hållbarheten vid renoveringsobjekt, hur får de hela områdensom länge haft ett dåligt rykte att bli socialt hållbara där stort fokusligger på att anställa långtidsarbetslösa.I Göteborg och i föreningen Byggemenskap fokuserar man på attföra in den sociala hållbarheten vid nybyggnation och hur vi kan byggahyresrätter som har en lägre hyra än nybyggda lägenheter i dagslägethar..

The aim of this project is to optimise the sawing patterns used for sawing Scots pine at Säters Ångsåg AB. The thesis has a theoretical approach and does not claim to be fully applicable in a practical point of view. The input used in this project is last year?s sales volumes and prices of sawn products. The input of the timber is collected from the database ?VIOL?.

Syftet med studien var att studera nya läroböcker i kursen naturkunskap 1a1 på gymnasiet. Böckerna analyserades utifrån den nya ämnesplanen i naturkunskap samt ett formulär med stödfrågor. Resultatet gav att ingen av de analyserade läroböckerna uppfyllde ämnesplanens mål och centrala innehåll på ett tillfredsställande sätt. Den största bristen fanns vad gäller ämnesplanens mål om att eleverna ska utveckla kunskaper om olika livsstilars konsekvenser för den egna hälsan samt folkhälsan. Ingen av böckerna berörde detta på ett tillfredsställande sätt.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

The aim of this study has been to understand how teachers make pupils come up with new business ideas. This is relevant as the schools in Sweden has to have entrepreneurial teaching in their education. To get an understanding of how teachers teach the pupils how to think differently so that new business ideas can evolve the study is based on interviews with five successful teachers. The teachers have all had pupils that during one year have had their own almost real companies that they have to manage. They start with inventing a new business idea and then they produce the product or service they decided to sell.

Luftvägssjukdomar är ett av de vanligaste hälsoproblemen hos kalvar och utgör en betydande kostnad för branschen. Luftvägssjukdomar är komplexa till sin natur och uppkommer endast då en kombination av faktorer som inkluderar djuret, miljön och infektiösa agens förekom-mer. Ofta är den primära patogenen ett virus och den påföljande lunginflammationen orsakas av bakterier. Ett bidragande virus, BVDV, har genom ett frivilligt kontrollprogram utrotats i Norden och det finns potential att utrota även BRSV. Genom en ökad förståelse för biosäker-het och hur ventilation av mikromiljöer, gruppstorlek och ålderssammansättning påverkar smittrycket och luftvägshälsan hos kalvar kan byggnader och management-rutiner som mini-merar risken för respiratoriska sjukdomar utformas..

During the past year it has been made possible to buy back a company?s outstanding stock. This is done in order to change the capital structure towards a situation with less equity. A change in capital structure means a change in the cost of capital for a company and by that a change in the value for the stockholder. This Master Thesis studies the relation between capital structure and business risk.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

The purpose of this essay is to present a thesis work that has been executed during a period of 10 weeks, as part of a bachelor degree in Graphic Design and Communication and also to present what has led to the design of a sales brochure for the freely distributed lifestyle magazine LKPG. The purpose of the thesis work was to examine the answers to the questions ?What does clients and local company owners want to achieve from their advertising in newspapers and magazines?? and ?How should a sales brochure for a freely distributed lifestyle magazine be designed to be at most advantage and out of most interest to its clients??. The work has been carried out through an competitors analysis, qualitative interviews, literature studies and a survey on the target group. The findings of the work are that the market of freely distributed  magazines, both nationally and locally, is extremely wide and has many similar competitors.

How important is the relationship in B2B? (Business to business) 2. Will VRM change the work with relationships within B2B? 3.

 The luxury market has steadily grown from the industrial revolution and onwards. Changes in society, trends and the increased living standards has enabled more people to consume luxury goods.The world is going through a major economic crisis at the moment. Studies shows that companies that have focused on added value rather than lowering prices has survived past financial crisis. It is also obvious that companies act very different during times of crisis. Adding to the problem is trends that point to a more careful consumption and environmental awareness.
