Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with support against the ground for the head. The lying behavior can be affected by external stimuli such as age, food intake, bedding materials and if the horses feel safe or not. This study investigates the lying behavior of horses on different bedding materials; wood shavings and filled rubber mats (HIT SoftBed®).

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.

Every year many dogs in Sweden are bitten by the adder, a venomous snake (Vipera berus). Despite the fact that adder bites are so common in dogs there have been few investigations made that study the effects of treatment with glucocorticoids, a drug that is commonly used. We have carried out a literature study concerning adder bites in dogs and a prospective study where case history, clinical signs and treatment have been recorded in dogs that were presented at two veterinary hospitals after a confirmed or suspected adder bite. Fifty three dogs were included in the study out of which 22 were treated with glucocorticoids. In our study, the group of dogs treated with glucocorticoids was compared with the group of dogs that did not receive glucocorticoid treatment by the owner or on arrival at the clinic.

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.

Holmen Skog has only five out of 70 wood buyers who are women, This report is seen as a step in the process towards gender balance in the company. This is a problem that is equal over the entire forest industry in Sweden. They all think that sexual equal workplaces are very important to remain competitive, see things from different perspectives and development of the company. The survey was done by sending out questionnaires to all women who work and have worked as a wood buyer at Holmen, and as many men of both categories. These four categories became a total of twenty persons. To map the industry another questionnaire was sent out to the six largest forest companies in Sweden. The survey found that female wood buyers not finished their work earlier than men did, as they thought before.

This thesis analyses the prerequisites, profitability and competitiveness of eucalyptus plantation on the Iberian Peninsula and in Brazil. The thesis has a macro perspective and analyses a typical hectare of eucalyptus in each studied region. A survey methodology was used as a strategy to cover a broad perspective using expert respondents. The regions studied on the Iberian Peninsula were the ones found suitable for eucalyptus plantations from an economic point of view. The studied regions were Huelva in the South West of Spain, Galicia in the North West of Spain and Portugal.

The aim of this study was to increase the knowledge about and deepen our understanding for people who are treated with dialysis in aspects of quality of life and coping strategies. The research questions were: How does the scientific literature describe quality of life and coping strategies from people?s perspective who are treated with dialysis? How does dialysis affect patients and their lives? How/what can the nurses do for people who are treated with dialysis to keep or improve their quality of life. The result is based on eight scientific articles and after interpretation of the result we found six themes that describes how patients have to restructure their lives to a new normal life, how they adapt to a life with dialysis treatment, how dialysis affect their physical condition, witch meaning does the family and others have, how they keep their self-esteem in relation to the dependence of dialysis treatment and which factors are associated with a long life with dialysis..

My diploma thesis has focused on creating a proposal for a Viking center in Stockholm that meets the international interest. A building dedicated solely to the Viking heritage. My ambition has been to give the Viking center an architecture that can serve as scenography for its exhibitions and to give the visitors a feel for the Vikings that they have been craving.  A boat-shaped building in tribute to the Vikings boat building skills with curved stems of equal height that gives a familiar silhouette to the city.  A wood building constructed of curved beams and wood columns painted with tar..

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.
