Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

Regeneration with scarification and planting is a well known method, but the plants have a tuff period in the beginning. Decease of plants comes from pine weevils, dry weather, browsers, wrong method of scarification and wrong time for the planting. These are some courses why not every planting gets successful. The purpose with this study is to investigate witch time of planting gives the best result, spring or autumn planting and to give a answer of witch factors are the main course of deceases. The goal is to have the study to decide witch time to plant after final felling. The choices of plantings were maid from a period of three years. Spring plantings were from year 2005, 2006 and 2007 and autumn plantings were from 2004, 2005, and 2006.The purpose was to compare differences in deceases at the same spring weather.

There have been several projects with solar installations in Sweden, and Sala-Heby Energi (SHE) wanted to create a solar plant. The question answered in this thesis is whether it is economically viable to create such a source of sustainable, renewable energy. The plant would be built with the help of the financial effort from 120 customers. This economic union would sell the electricity to the SHE, for SEK 4.50 per kWh up to a certain level over a period of 10 years. It would be a long term commitment to environmentally friendly electricity, using solar cells which convert sunlight directly into electricity.In year 2009 there was introduced a new state aid for photovoltaic systems, to create an increased and continuing interest in solar cells.

The austenitic stainless steel 316L has been compared to duplex stainless steels to be able to highlight a choice of material for manufacturing of spare tanks used for cooling water at nuclear power stations on the Swedish west coast. In this report 316L and the duplex stainless steels 2205, 2304 and LDX 2404 have been compared according to corrosion resistance, strength, manufacturing aspects and prices. The steels arranged by increasing corrosion resistance: 316L < 2304 < LDX 2404 < 2205. The steels arranged by increasing strength (considering the thickness of the plates needed for construction): 316L < 2304 < LDX 2404 and 2205. The steels arranged by increasing price/tank: 2304 < LDX 2404 < 2205 < 316L.

The purpose of this thesis is to explore the situation for ebooksin Swedish public libraries. The background is anincreasing lending of e-books in public libraries, with anacquisition model formed when e-books were more of anexperiment in a few libraries. The debate has escalated in therecent years and in this thesis I aim to investigate thelibraries? experience with e-books and the current pricemodel. The empirical material comes from interviews witheight head of public libraries in the Västra Götaland region.As theoretical background, I have used Michael Buckland?sfour roles of collections and price models from Lee andBoyle.My results show ambivalence with the price model.

Around 85 percent of the total population in Sweden today lives in an urban environment. This means that the nature within the urban areas has come to play an important role for the human well being. At the broader picture, the nature within urban areas is profitable in many ways. It is therefore important for the municipalities around in Sweden to work for sustainability within the urban areas. Linköping adopted an environmental policy, in year 2001, from the delegate of the municipality.

Ravelsmarks gård have now reached the stage when there are few options for the future. The options are either a construction of completely new farm buildings or a winding up of the milk production. Present on the farm today there is 65 dairy cows plus recruitment. 44 cows stand in long-stalls and 20 cows stand in short-stalls. The objective of this study was to examine the profitability of a completely new cowshed. In order to get costs for investments different milking systems and equipment for feedstuff have been compared. The systems in the investment budget have been chosen on recommendations from advisers, salesmen and on the basis on what is suitable for the farm. One system where a so-called mix feeder wagon is used for the roughage seemed to be best suited for Ravelsmark. The different prices obtained for the manure well show that there are possibilities to decrease the investment costs.

This paper is about how transport companies in the future will be able to adapt their activity to an environmentally sustainable development without the effect of negative company economic consequences. Today, the environmental threat is a global problem and knowledge about that effluent of carbon dioxide have a negative impact on the climate is generally known. A transport system that works well is important for Sweden, but the sector has a negative impact on the environment. Regulation and legislation for increased environmental requirements often meets resistance and fear that the work will be hampered by increased costs for environmental work that can lead to an international decrease in competitiveness. The transport companies have outside pressure from the society to do something about the environmental issue, however the companies? customers are not ready to pay a higher price for environmental work.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

The background of this research is that Swedish food products have hard to compete at the home market, depending on imported food products that increase more and more for every year that pass by. The ethic values LRF associate with Swedish food products, many customers have hard to put in relation with condition of foreign agriculture. Most customers today inquire high quality, safety and convenience in the food which they are eating. The source of their food seems to have less meaning. Many restaurants and bigger households appreciate Swedish food products and wants to buy them but price differences against foreign wares are to high. We have done oral interviews with wholesale dealers, restaurants, public purchasers and with different market organisations, there we have discussed buying strategies, the way they see the primary producer, the conscious of guests, choice and attitudes to Swedish and foreign products, distribution of power in the food market chain and to what position and suspension, they want the ranks of suppliers to have. The result shows the share of imported wares within restaurants and bigger households are at a high level and will continuing increasing. Within these sectors the final consumer in many cases put less effort in the origin of the raw source of food.

Printed newspapers are on the decline, while digital versions are in rapid growth. Consequently the industry must draw up new business models around the digital format - models that can produce revenue streams equivalent to those that the print format used to produce. However, after a decade of 'free' online news, consumers now hesitate to pay. In their struggle for survival, strategic pricing is a central issue for newspapers. This study aims at describing how Swedish newspapers price their digital content, by analyzing their pricing processes and five factors that may influence the choice of paywall and price levels.
