Contortatallens odlingsvärde i Götaland

The third most common conifer in Sweden is Pinus contorta (lodgepole pine). It originates from the western part of North America and was brought here in the end of the 1920s. The lodgepole pine is today allowed for commercial plantations in central and northern Sweden, excluding high altitude locations. Since 1979 only plantations with scientific purpose are allowed in south-central and south Sweden. This document is focused on how lodgepole pine manage perform compared with Pinus sylvestris (Scots pine) in the southernmost part of Sweden, Götaland. The idea came from the fact that the Swedish government is evaluating a notification from the National Forest Agency that suggests lodgepole pine to be allowed for commercial plantation even in southern Sweden.

Thuja plicata - etableringsförsök av jättetuja med fyra olika provenienser

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.

Biobränsle från det jämtländska jordbruket : en studie om lantbrukarnas alternativkostnader vid odling av rörflen

The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.

Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun

Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.

Beräkning av värmeförluster och energieffektivisering av elbussar

The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå.                               The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Sensory profiling of Swedish white wines and a contextual analysis of Swedish viticulture

The aim of the study is twofold, to generate a sensory profile of Swedish wine today and to investigate the opinion of both wine producers and wine experts on viticulture in Sweden and wine from grapes grown in Sweden, achieved through a contextual analysis comprising a literature study and interviews with wine producers in Sweden and Denmark and wine experts from Sweden and Germany, and a sensory analysis at the company Ipsos. ?Mixed methods? was the chosen research strategy as the semi-structured interviews gave qualitative results and the sensory analysis would give quantitative results displayed as spider charts. There is a lack of studies investigating how the Swedish wine is perceived by consumers and consumers might be unaware that the Swedish wine, established through ?trial and error?, is increasing in quality every season, creating a need to display the sensory profile of Swedish wine to strengthening the perception of Swedish white wine. This study shows that the Swedish white wine today is a wine with a fresh, citrusy and flowery aroma and a fresh, citrusy and green apple taste, however, a sensory analysis cannot show if the attributes are those that are desired by the customer, a consumer test is necessary to conclude that. Trends point towards locally produced products, one reason why Swedish wine has great potential, yet the future needs to be secured through job opportunities and education. Creating an approval system for Swedish wine is suggested as a future improvement, it is a common procedure in most wine regions.

VÄRDERING OCH REDOVISNING AV FÖRVALTNINGSFASTIGHETER I KONJUNKTURNEDGÅNG

In the year of 2005 the international standard IAS 40 came in to use in Sweden, this lead to an opportunity for the corporations to choose either to evaluate their investment properties according to the historical cost accounting principal. The model contains the obtaining price with reduction for the planned writing off. The alternative that IAS40 offers is the fairvalue principal, which evaluate the investment properties by consideration of the income versus outcome and surrounding factors for every accounting periodSince the fairvalue is buildt on numbers the corporations them self choose what to publish and for how long the value depreciation should be lasting before it should be taken up as an unrealized value change in the reporting material. This means that there is a big chance that the evaluation can be distortedSince we just recently have had strong cyclical variation and are on our way from an excess boom into a weak economic climate, this will be the first study performed about fair value in a weak economic climate since the adoption of IAS40.The purpose of the essay is to find out how well the booked value of investment properties owned by corporations listed on the Swedish stock market accord with the fairvalue that the market and the Swedish property index indicates on. To be able to test this connection we gathered information from the corporation?s annual reports which we compiled to see how the market comprehends.

Koldioxidavgång vid ekologisk odling på organogen jord

The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.

Ledarens och deltagarnas beteende vid drop-in-idrott : En kvalitativ studie kring drop-in-idrott på Ersboda

May 2010 a project called drop-in sports was started to get boys and girlsin the ages of 13-20 more physically active and keep them away from  committing crime. With the slogan ?come as you are, whenever you want and do what you want for free ? spontaneous sports was organized. To evaluate the project a research of the activity was carried out, where two of the objectives were to investigate how responsibility and empowerment is taken. Twelve hours of observations studies were used to collect data about leadership decision-making and democratic values in forms of respect, everybody?s right to play and influence.

IDA Klimat och Energi - Ett lämpligt och användbart alternativ för noggrannare energiberäkningar på VVS GRUPPEN AB?

I juli 2006 trädde BBR:s nya krav om byggnaders energiförbrukning ikraft, vilka jämfört med de tidigare kraven väntas medföra förändringar för hela byggprocessen vad gäller hanteringen av energifrågor. De hårdare kraven kommer bland annat i skepnad av ett nytt begrepp, ?byggnadens specifika energianvändning?, ett begrepp som med stor förmodan kommer att ställa både högre krav på utförande av energiberäkningar i ett tidigare skede av byggprocessen samt med större noggrannhet. På VVS GRUPPEN AB i Lund utför man egna grövre energiberäkningar i samband med projektering i ett ganska tidigt skede av processen, främst beräkningar för hand, för att i ett senare skede låta en byggnadskonstruktör genomföra mer ingående energiberäkningar. Med de nya hårdare kraven uppstår ett eventuellt behov av att framöver utföra egna energiberäkningar på en noggrannare nivå redan i ett tidigare skede. BBR anger inga krav om metod för beräkningarna, utan lämnar upp till var och en att välja lämplig metod för aktuellt projekt. I samarbete med VVS GRUPPEN utfördes därför en undersökning av en alternativ metod, energiberäkning med hjälp av simuleringsprogrammet IDA Indoor climate and Energy. Undersökningen begränsades till ett pågående projekt i form av en ny biblioteksbyggnad i Lomma, samt till att huvudsakligen syfta till beräkning av den specifika energin.

Vattenringar : En individstudie i folkmusikvågens efterdyningar

This essay is about two Swedish folk musicians, Anders Rosén and Leif Stinnerbom, who have been playing two important rolls in the developing process of Swedish folk music, on their separate ways. The main part of this work is focused on the era called ?The Folk Music Vogue?, which was the era when my informants were in the limelight on the Swedish fiddler scene of the 70s.Our music culture is constantly lying under the change of progress and I find it interesting to reflect how these kinds of changes are affecting the role of the musician.In this essay I am reflecting on the different perspectives of the musicianship according to my informants and how they both are referring to their role as musicians. The purpose is further on to see how they have been relating to the change of progress on the field of the Swedish folk music during the 70s and up to this date. Throughout interviews with the informants I am analyzing their personal relationship to their life as folk musicians.

Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.

Hur man blåser liv i en slumrande organisation : En studie om organisationsutveckling och hälsopromotivt arbete

This is an essay about health promotion and organisation development. The problem concerning all health issues that can be tied to work related illnesses has long been a problem in Sweden. For example did this problem alone cost the Swedish government 25 million crones a day between the years 2000-2001. This is a major issue and there is lots of money to save in this area. This is why we wanted to research how to promote health by changing the structure of the selected company.
