Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

This study concerns how organizations manage various problematic areaswhen implementeing Business Intelligence and experiences from BusinessIntelligence project failures on management level. In order to highlightthese questions, we have carried out interviews with four organizationswhich have great experience in working with Business Intelligence on adaily basis.The result of the study shows that all organizations deal with difficultiesregarding cost-benefit issues and justification concerning BusinessIntelligence investments. The result also showed that the organizationsfaced difficulties with integration concerning time and cost. Documentingand securing support systems presented different attitudes between theorganizations, primary in the question about sub complements to BusinessIntelligence and in the way that they were documented. In the discourse oflegal issues and privacy the majority of the organizations chose not to storepersonal information relative to legal security demands.

The purpose of this master?s thesis is to study attitudes and standpoints among a few librarians towards literature with state supported distribution provided by the Swedish Arts Council. By qualitative interviews with librarians at five different public libraries, the thesis examines which attitudes that flourish concerning the titles, how the circular of books is treated, where the titles belong on the literature map and if the system is producing a standardisation of this literature and if the conception of quality is relevant. We also study how the librarians relate to intentions of the Swedish Art Council with the distributed titles and how they regard their availability. Our theoretical framework is based on Hans Hertel?s model of five literary circulations and Theodor W.

The thesis work has been carried out at Volvo Aero Corporation (VAC) in Trollhättan. VAC has entered a partnership as developing and producing partner with engine manufacturer Pratt & Whitney and is currently at the starting phase of producing the turbine rear frame (TEC) to the engine PW1000.The purpose of this study was to create a report on process level that describes the conditions and the potential with PW1000 TEC to reach the product cost calculation taking into account lead times and describe alternative method solutions.The report describes a comparison between the present flow (2012), a flow based on product cost calculation (2016) and a potential flow (2016). The work has mainly been based on acquiring the knowledge and information available to inspect the present flow; this has been done by workshop observations, meetings and gathering of the information that is available on the work site for the PW1000 TEC.The information obtained has been merged into an Excel document, called Roadmap. It serves as a roadmap with current situation as the start and the potential flow for 2016 as the goal. With the roadmap as a tool, assumptions have been taken considering the flow and how it will change, where processes have been eliminated, reduced or marked as a problem..

During the early 1990´s, the Swedish commercial air traffic was de-regulated and the new market-condition made it possible for low-budget airlines to enter the Swedish market. The former monopolistic airline company, Scandinavian Airline Systems (SAS), was facing a new type of competition which had the advantage of offering much cheaper air trips than SAS. Adding the decrease of profitability that struck SAS as well as other airline companies after the terrorist attacks on the 11th of September, forced them to carry out a mayor reorganization programme. The programme, called ?Turn Around 2005?, was a direct economical measure that begun in 2002 and lasted until 2005 and resulted in a cost saving of 14,5 billion SEK as well as a notice or a transfer of 6000 employees.The purpose of this essay is to investigate if the opinion of the consumer, the image, corresponds with the profile that SAS wishes to mediate today.

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.

Bakgrund: Dagens industriföretag har ägnat mycket tid och tankeverksamhet åt att förbättra produktiviteten men i regel betydligt mindre till att beräkna enskilda produkters kostnader. Allt högre krav ställs på en kundanpassad produktion med differentierade produkter. Produkternas heterogenitet innebär även heterogen resursförbrukning och det gör det svårt att veta vilka kostnader en produkt verkligen orsakar. Inom ABC är det kostnadsdrivarens uppgift att koppla samman resursförbrukningen med produkterna. Valet av kostnadsdrivare kan ge stora effekter på produktens kostnad och visa att produkter som tidigare betraktas som lönsamma säljs med förlust.Syfte: Syftet är att beskriva och analysera problematiken kring val av kostnadsdrivare.Genomförande: En fallstudie har genomförts kring val av kostnadsdrivare vid Swedish Tissue.Resultat: Det finns inga optimala kostnadsdrivare utan en komplex avvägning med kalkylens syfte i bakhuvudet krävs.

People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

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.

In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.
