Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

AimThe aim of the present study was to evaluate physical performance according to ?fysprofilen? in skiers of the Swedish mogul ski team and to compare their physical performance at three test occasions during one year.MethodsAll eight elite mogul skiers at the Swedish national mogul ski team during the seasons 2011/2012 and 2012/2013 participated voluntarily in this study. The test battery ?fysprofilen? was performed at three test occasions, October 2011, May 2012 and October 2012. Muscle strength was evaluated with squats, bench press and grip strength; power was evaluated with power clean, squat jump, countermovement jump with and without arm swing, Harre´s test and the 30 meters sprint.

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.

Environmental subsidies are used as incitements to farmers for development of sustainable land use. In 2014, applications for funding constructed wetlands were not available. This paper examines the environmental consequences of this lack of funding in one intensively cultivated region Skåne län, southern Sweden.A review of wetland applications between year 2007-2013 show that the average rate of applications has been 31 projects per year with a wetland size of 4,48 ± 1,61ha per project (mean±95% CI). Based on interviews, the result suggests that the lack of funding in one year leads to between 102 and 140 ha of constructed wetlands that is not built. This correspond to a total loss of increased nitrogen retention capacity between 6,0 and 91,7 tons/year and a loss of increased phosphorus retention capacity between 0,17and 2,1 tons/year in the drainage basins of Skåne.Further the interviews show that continuity of environmental regulations and funding is important for the farmers? interest in environmental measures.It is concluded that the total loss of increased retention capacity is small compared to the annual transport of nitrogen and phosphorus in the drainage basins.

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.

This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.

BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.

The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year.

The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.

This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..

During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.

The purpose of this study was to build a database for point-bearing piles in dense noncohesive soil, predominantly moraine. Further, the database was analysed and areas with difficult geotechnical conditions was identified.The database includes for point-bearing piles driven to refusal in moraine. Piles with mainly shaft friction have been excluded. Only concrete piles have been included. Geographically the database covers almost all geotechnical conditions of Sweden.
