Vindkraft eller kärnkraft - En jämförelse
The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).
Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud
ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using phone interviews.
"Nytta vet jag inte om vi har, men vi har roligt i alla fall": En studie av äldres IT-användning
The aim of this Masters thesis is to examine the use of IT, that is the Internet and other applications of personal computers, among seniors 65+. It also deals with issues of access to IT for seniors in public libraries. The theoretical background of the study consists of Rogers "Diffusion of innovations", Hektors categories of information activities, and the Swedish IT-commissions categories of motives and prerequisites for the use of IT. The research questions focus on factors motivating the use of IT, the extent and the purposes of IT use, the consequences and the barriers that IT-users experience, and views on IT in public libraries and IT courses, respectively. Qualitative interviews were carried out with nine senior IT-users.
Investeraravdraget : En ändamålsenlig lösning på den skattemässigt asymmetriska behandlingen av bolag finansierade genom eget kapital respektive lånat kapital?
Companies financed through borrowed capital are allowed a tax deduction for the costs re-lated to their borrowed capital. A similar tax relief for companies financed through share-holder?s equity does not exist, why these companies are taxed higher than companies fi-nanced by borrowed capital. The result is that there is an asymmetric tax treatment of companies depending on how they are financed.The autumn of 2012, the Swedish government presents a proposal for an investor deduc-tion which seeks to equalize the above mentioned asymmetry. The proposed investor de-duction is a tax relief for investments in shares in a startup- or small company equal to 50 percent of the acquisition cost of that investment.The venture capital deduction, which in this thesis is treated as an alternative to the inves-tor deduction, is an interest-free tax credit which significate that two-thirds of the acquisi-tion cost is deductible from taxation at the time of the acquisition.
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.
Har vindsvåning blivit ett sätt att leva? : Gentrifiering ur ett svenskt perspektiv
It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..

Intuberingsmetoder och alternativa metoder att tillföra inhalationsanestetika för allmän anestesi på kanin
Handling of animals during anaesthesia is an important field in the profession as a veterinary nurse and in which intubation is an essential part. Hence, adequate knowledge is necessary for the welfare of the animal.
The objective of this literature study was to make it useful and trustworthy for veterinary nurses. It is intended to describe and summarize existing scientificity with its benefits and disadvantages within the different areas of intubation techniques and alternative methods of inhalation anaesthetic supplementation for general anaesthesia in rabbits.
Endotracheal intubation in rabbits can be complicated and technically demanding due to the anatomy of the oropharynx including the narrowness of this structure, a relatively large tongue, large incisors and a limited mobility of the temperomandibular joint. The obstructed visualization of larynx and the rabbit?s tendency to develop laryngospasm contributes to the difficulty of intubation.
Rabbits are susceptible to tracheal injury and multiple intubation attempts can cause tracheal lesions due to repeated damage to the tracheal mucous membrane, although damage can occur after a single intubation attempt as well.
An ETT (endotracheal tube) with or without a cuff can be used during orotracheal intubation in rabbits.
"Fettskatten" - ett sätt att banta de samhällsekonomiska kostnaderna till följd av övervikt?
The rise in prevalence and severity of obesity and related diseases imposes increasing costs on society. The objective of this thesis is to discuss and estimate the possible effects of a so-called fat tax as a tool for minimizing these costs. Two alternatives for differentiation of the value-added tax (VAT) on food are compared. The first alternative is an increase of the VAT levied on food containing saturated fatty acids. The second alternative is a subsidy on fruit and vegetables in the form of a VAT at zero percent, instead of today?s twelve percent.
Vakuumisolering ? Ekonomiskt försvarbart för småhus?
The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.
Design of Production Contracts : an examination of the Findus pea production contract
The Swedish processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.

Informationssökning i elektroniska informationskällor Valmöjligheternas vånda
The purpose of this thesis is to examine which factors influence librarians selection of electronic information sources, and to investigate whether librarians use of search strategies and search tactics changes depending on which information source they use. The electronic information sources are: online databases, Online Public Access Catalogues OPAC, World Wide Web, and CD-ROM databases. The theoretical framework is based on step 3 Select a source and step 4 Formulate a Query in Marchioninis information seeking model. The search strategies are divided into two categories: analytical and browsing strategies. In order to supplement the theoretical framework with empirical facts, 8 librarians were interviewed.
Kartläggning av rapporterade olyckor med djurtransporter i dagspress i Sverige
When farm animals are transported there are several factors that can affect their welfare. If the vehicle has an accident the welfare of the animals transported will probably be compromised.
The aim of this study was to make a survey of accidents with animal transportation vehicles in Sweden. The survey included the number of accidents from January 2000 to May 2014, the cause of the accidents and how the animal welfare was affected by the accident. The authorities which were likely to have reports about accidents involving animal transports were contacted. There were no collected records about transportation accidents and the authorities referred to eachother for information.
