Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.

The main purpose of this study is to investigate how to reduce the high, and every decade raising, pre-clearance cost. The pre-clearance is today carried out with a brush saw and paid per labour hour. All small trees not suitable for pulpwood are removed to simplify the later work of the harvester. The study compares the economic results from thinning of four parcels each treated differently regarding harsh or light pre-clearance and extraction of only pulpwood, or both pulpwood and fuel wood. In this type of spruce stand the study indicates that a lighter pre-clearance, followed up with both pulpwood and a fuel wood extraction, has a much better economy than the traditional method of hard pre-clearance and only pulpwood extraction..

In 2003 the deciding political council in Bromölla municipality requested that an overhaul on the committee and public administration structure should be conducted. In the report Bromölla was characterized as a traditional organization with a low degree of change. This case study will examine why the organization previously has been reluctant to change its structure and why they are willing to do so now. In the pursuit of this objective I conducted document studies, interviews and observations. I have used theories on, institutional change and organizational culture to enlighten this.My findings shows that the traditionalists within the organization has greatly affected this reluctance towards change, in the deciding council 39 % of the representatives are 60 years or older.

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

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.

When an organisation is going through a work of change, it is highly important that both management and employees has a healthy communication in order to make everybody feel involved. It is then important to be observant for both the managements and employees thoughts and ideas.This study has been performed on an upper secondary school which is performing a work of change. The change has divided the employees in three different groups. One, which thinks the change have evolved the organisation to something better. The second group of people means that it is preventing individual development of competence.

The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.

This thesis aims to describe and characterise the foreign policy change the United States has experienced towards Europe. This thesis claims that the United States is presenting a more supportive attitude today towards the development of the European Union. This more positive attitude has developed during successive U.S. administrations and has become visible since the end of the Cold War.Washington is today less ambiguous and less ambivalent towards the integration of Europe. The United States appreciate that a common foreign- and security policy in Europe is in accordance with American interests.

In Sweden, there an increasing need for transport and this leads directly to fuel demand of the transport sector is expected to increase. Both politicians and industry believes that renewable fuels are a realistic and significant method to reduce the transport sector's environmental impact. This study aims to document the Swedish haulage contractor?s attitude to biodiesel. Also to document the strengths and weaknesses of biodiesel, based on opinions from the ultimate consumers.

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.

The increasing competition is making increasing demands of today's businesses to be changeable. Change projects have therefore become increasingly common in order to satisfy market expectations. These projects have often proved difficult to implement and fail rather than succeed. There are many people who reflect on why this is and theorists are increasingly reasoning about the importance of communication in the change process. This is something that has given rise to a new area of expertise called change management.
