The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

This thesis examines the effects of electricity visualization in an office building. The subject was investigated through the creation of a web based visualization tool that was made accessible to the about 1500 employees in a large office building. The visualization was available for three weeks. During this period interviews, user studies and observations took place in order to evaluate what, if any, effects the visualization had on the attitudes and behaviors in the office. Electricity use data was collected and analyzed to see if the project had a statistically significant effect on the electricity consumption in the office.The results from the interviews and the data analysis indicate that no reduction in electricity consumption took place, and a number of factors that could increase the chances of success were identified.

The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes.What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child?We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community.The people we interviewed think differently about collaboration. The municipality have different workforms.

This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules.

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

In Sweden, all milk needs to be pasteurized. Unpasteurized milk [ OPM ] may only be sold in a smaller scale directly from the farmer to the consumer. The law was introduced in 1939, to prevent tuberculosis, which poses no threat today. There are other reasons, such as keepability and risk of pathogenic bacteria, why milk is pasteurized. Despite these risks, many consume OPM.

The principle of proportionality is considered one of the most important contemporary legal principles on which it intends to protect individual citizens against disproportionate action by the authorities. This aroused our interest prior to this study. The essay reveals how such behavior might look like and how courts have chosen to adjudicate in cases where the individual has been discriminated against or subjected to unreasonable demands in public procurement. That section of the law that were current throughout all court cases are Public Procurement Act (2007:1097) LOU. That which we have seen in every court case is that the applicant has not received a proper fair chance when the requirements of the contract often been asked in a way that either exclude the smaller applicant company or rule out various potential applicants parties due to excessive and sometimes unnecessary requirements.

The Motor Group of the European Council was commissioned in the autumn of 1997 to prepare a proposal for a new European Bus and Coach Directive. In the beginning, most of the Member States did not have the accessibility requirements as their main concern; still a smaller network with actors from the National delegations from Britain, Germany and Sweden would influence the other National delegations in the Council group to finally agree to retain the requirement of accessibility of the Directive. Within the EU decision process, the European Disability movement acted as a strong player during the whole negotiation process using the proposal to a new Bus and Coach Directive as a tool to influence key actors to go towards a Directive with a strong approach for accessibility.Policy Transfer and Policy Transfer Network are used as analytical tools to understand and structure the transfer of the question of accessibility during the negotiation process. Actors understanding how the bureaucratic process works within the EU decision system have a chance to contributing for the changes in the directions they wishes for within a range of policy areas. The principal aim of the Directive was to guarantee the safety of passengers and to provide technical prescription in particular to wheelchair users.

The purpose of this study was to look for tendencies that social media can contribute to exposing users to a stronger perception of opinion polarization, and further to see if the daily presence of social networking sites can put normative pressure on the users. The study was made using a survey with participants from Umea? University during the time frame of november-december 2014. The theoretical framework behind the study was mainly drawn from The Spiral Of Silence by Elisabeth Noelle-Neumann and was further supplemented with more current research, studying the effects from The Spiral Of Silence in the modern and more fragmented media landscape that exists now then when her theory was written. Further theoretical tools for analysis of the results came from Michel Foucault and his discussions in Discipline and punish, specifically his views on how surveillance can be discontinous in practice, but still permanent in it?s effects.The results of this study indicates that social media users tend to isolate themselves from uncomfortable opinions, and do not follow or read opinions they do not already agree with.

Background: The project controller is a function witch evolved due to the strong gaining ground of project operation. Why the area of the project controller is interesting to study is explained by the fact that increasing knowledge of this function is important in order to make project operation work well. The fact that opinions in this field disagree, further increases the interest of the field. In order to study the function of the project controller three companies have been singled out. They are IFS, Intentia and Saab Bofors Dynamics.

(In our case, video games).

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

ABSTRACTJuvenile is a phenomena that more or less always has been around in our societies. From a society perspective, a crime is committed if actions that the legislative power of state consider as unacceptable or actions that are punishable. There is no particular explanation to why certain people become criminal; crime can be caused by many different factors at the same time. There are several types of justice. In this essay, it is reparative justice for shoplifting in force, that will be illustrated.The purpose of this essay is to investigate how the shopkeepers experience incidents such as shoplifting or theft in their stores, and how they will react and act if they will be exposed by circumstances like that.
