Syftet med examensarbetet har varit att undersöka möjligheterna för ett system till Skogsvårdsstyrelsen Värmland/Örebro, där uppgifter ska registreras i handdator vid fältbesök och därefter verifieras och slutlagras i Skogsvårdsstyrelsens databaser. Under arbetets gång har olika skogsorganisationer och företag intervjuats för att ta reda på om de har någon lösning som skulle kunna passa för Skogsvårdsstyrelsen. De lösningar som används av andra organisationer/företag har analyserats för att få fram för- och nackdelar med de olika varianterna. Slutprodukten innefattar inte någon prototyp på hur uppgiften skulle lösas utan föreslår olika verktyg som skulle kunna användas. Arbetet har grundats på litteraturstudier om införande av GIS i organisationer samt intervjuer och brevkontakt med personer och företag som arbetar med eller har kunskaper om fältGIS.

The thesis aims to understand how learning processes are affected when an organization split into two separate organizations. The study is designed as a single case, covering a new government agency?s takeover of a core activity from another agency and the use of a purchase-provider split between the agencies, providing the new agency with IT-services. The findings revealed a difference in productive system and knowledge types between core- and IT-activities. The core activity was found to be dominated by explicit knowledge while the IT-activity seemed to be dominated by a mix of explicit and tacit knowledge.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

I Sverige tillverkas betong normalt med glaciofluviala grusavlagringar(naturgrus). På senare år har tillgång på naturgrus blivit starkt begränsade i vissa regioner och man vill av miljöskäl minska förbrukningen av det som återstår. Återvinnig av material som kan ersätta detta är både bra av miljöaspekt samt öppnar väg för produktion av betong med nya egenskaper.Med lättballastbetong avses betong i vilken ballastmaterialet helt eller delvis består av någon typ av lättballast som har en partikeldensitet som är markant mindre än vad som är normalt för normala bergartsmaterial såsom granit, gnejs eller kalksten. Lättballast är porös, dvs innehåller hålrum, och får därför lägre hållfasthet än normalballast. I lättballastbetong bestämmer lättballastpartiklarna många av betongens egenskaper, såsom hållfasthet, elasticitetsmodul och krympning.Examensarbetets inledande del är en state-of-the-art rapport som omfattar tillverkning av lättballastbetong i allmänhet, både i färsk och hårdnade tillstånd, samt dess beståndsdelar med fokus på skumglas som lättballast.

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

AbstractThis essay aims to problematize and illuminate the connection between special-education and nature-based activities. With a theoretical ground that is based upon a sociocultural perspective I consider the information from the field. Through a qualitative and critical perspective I performed individual interviews with five pupils from the sixth school-year in the Swedish elementary-school. I also performed Focus-group interviews with two educators and three teachers in the same school-form. By a Hermeneutical working-method I have found out that the informants in my survey have a common experience that activities performed in nature has a positive effect on learning.

Idag står bostads- och servicesektorn för närmare 40 % av Sveriges totala slutliga energianvändning. Flerbostadshus utgör ca 30 % av den energianvändningen. Därför är det viktigt att lokalisera energiparametrar och redovisa dess betydelse för energianvändningen. Samtidigt bör relationen mellan energianvändning och inomhusklimat analyseras, så att inte förändringar i energin medför till försämringar för inomhusklimatet. Baserat på identifiering hos energisparpotentialen hos parametrar, parameterbeteende och parameterkänslighet för energianvändning har i studien ett antal parametrar undersökts för ett flerbostadshus.

År 2009 antog IMO en ny resolution som innebär att ett nytt instrument gradvis kommer införas som obligatorisk standardutrustning på fartygsbryggan. Detta system förkortas BNWAS vilket står för Bridge Navigational Watch Alarm System och är kortfattat ett dödmansalarm som syftar till att varna vid otillräcklig aktivitet på bryggan. Detta system har funnits en tid men blir nu obligatoriskt ombord. Detta påverkar arbetssituationen och arbetsmiljön för vakthavande styrmän. Denna studie syftar till att undersöka vad styrmän som arbetar med systemet har för uppfattning och åsikter om systemet.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
