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 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.

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.

An open fitting is suitable for persons with sloping hearing loss and relatively good low fre-quency hearing. Sensory neural hearing losses often have this type of configuration. A large ventilation canal gives a greater feeling of comfort and less occlusion. The purpose of this study was to look at the hearing aid benefit of open fitted hearing aids. Self report question-naires were sent out to 102 patients who were given ReSound AIR during the year of 2006 in Uddevalla.

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

Ämnesord: Earnings management, loan loss provisions, konstaterad kreditförlust, Basel II,kapitaltäckning, bank, noterade, onoteradeBakgrund och problem: Justering av resultatposten loan loss provisions är ett vanligtförekommande verktyg för earnings management inom banksektorn. För att öka stabiliteten inombankväsendet så infördes kapitaltäckningsregleringarna Basel I år 1988 och år 2007 uppföljarenBasel II. Den senare antog en mer principbaserad roll och innebar en ökad kontroll och tillsyn avbanker. Det är därför intressant att studera huruvida Basel II har haft någon effekt på redovisningenskvalitet och därmed lett till reducerad earnings management.Syfte: Studiens övergripande syfte är att undersöka effekterna av genomförandet avkapitalregleringen Basel II på resultatposten loan loss provisions och earnings management inomdet svenska bankväsendet. Vidare studeras noterade samt onoterade banker för att utröna om detföreligger en skillnad i dess sätt att hantera loan loss provisions.Metod: För att uppnå syftet med studien så har en kvantitativ metod tillämpats.

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.

Background: Obesity has expanded to a nationwide issue that affects millions of people. The healthcare system struggles to handle the epidemic as the problem grows. Studies show that healthcare workers have negative attitudes toward obese and overweight people and that they lack knowledge and proper tools to support this patient group. Motivational interviewing (MI) is a known technique for initiating lifestyle changes with patients. Aim: The aim is to evaluate the effectiveness of MI as a tool for weight loss and sustainable lifestyle changes for people with obesity and overweight. Method: This study uses a literature review methodology with a systematic perspective. Data is gathered and analyzed to investigate how MI affects weight loss.

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

This essay is about the history of the hearing aid in Sweden, from 1930s until today. The hearing aid as an apparatus is described, and views by the users are presented. Articles and interviews have been used as source material to answer the main questions. In the essay, people who have written the articles, and the ten users being interviewed, describe how hearing aids are used in everyday life, and how users interact with people in general and how the hearing care system treats users. Another question regards how users perceive their own hearing aids from an aesthetic perspective.

The study emanates from the national quality registry for persons with severe and profound hearing impairment. The aim was to examine possible differences between signing deaf and adults with acquired severe hearing loss, with reference to self-assessed problems, how the hearing loss influences daily life.In total 234 adults aged 30-90 years were included (128 women, 106 men). In the registry, there are background variables and questions that the patients have answered. The results, indicated on a visual analogue scale (VAS) from 0-100, from a question ?To which extent does your hearing loss at present influence your life?? were analysed.The study was performed by pooling the results of VAS and dividing the patients into signing deaf and those with acquired severe hearing loss, and in age groups 30-60 and 61-90 years.

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.
