Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.

Today?s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation transformer´s secondary low voltage side that measures the low voltage network losses for that specific substation. By doing so, grid companies can, due to the calculation of the low voltage network losses, identify and address issues such as illegal power dissipation, unmeasured power outtakes, and unsatisfied technical documentation for the substations low voltage network.During 2012, Mälarenergi Elnät AB had a total electrical network loss (both medium and low voltage network losses included) of three to four percent of their total distributed electrical volume. Converting this energy volume into a monetary figure this accounts for a loss of around 30 million Swedish crowns.

The long-term external financing of a corporation is satisfied through the bond market where issues of index-linked bonds, which are discussed in this thesis, is one alternative. (Finnerty&Emery 2001) An index- linked bond is a debt instrument where the investor is guaranteed the principal and premium amount in real terms. As the bonds cash flows are indexed to the inflation this implies that the issuer of an index-linked bond assumes an inflation risk. Purpose: The purpose of this thesis is to describe and examine corporate motives for choosing index-linked bonds as way of financing their business. Realization: Primary data was collected through interviews with corporate issuers of non-swapped index-linked bonds.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.

The objective of this thesis was to get more knowledge about how to design a dairy farm reducing the working hours and the work tasks whit high work load. I will try to reduce the working hours and the tasks whit high work load on my own farm witch I am about inherit. Today, the old stanchion barn has room for about 60 cows and 74 young cattle and need two men to run it every day. The total acre is 188 hectare, 100 hectare forest, 65 hectare farmlands and 23 hectare natural pasture. I have studied two solutions. In the first solution, I will use my old barn for young cattle and build a new barn for the cows.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement.

The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization. The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing. The study is founded on a qualitative method that is based on a case study in eight companies.

There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.
