Bioenergy from the forest ? a source of conflict between forestry and nature conservation? : an analysis of key actor?s positions in Sweden
Bioenergy from the forest has been heavily debated in Sweden for several decades due to the interest of society to decrease dependence upon fossil fuels and limit the effects of climate change. The actual use of bioenergy from the forest has shifted over the years but increased during the last decades. Private actors within forest and nature conservation sectors play an important role for the development of bioenergy from the forest as well as for the debate and the implementation of political goals. Forestry in Sweden is characterised by ?freedom under responsibility? for private actors and the perspective of governance is valuable for studying actors and discourses.
Luft/luftvärmepump : - Med möjlighet till återvinning
Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.
Prissättning av ishockeybiljetter : Utbud, efterfrågan, monopol och nya arenor
This thesis is about pricing of ice hockey tickets in Swedish ice hockey. Ice hockey is a large sport in Sweden, with clubs that more and more are acting like companies. These clubs tend to build new arenas that in many ways change basic variables.The thesis is an analytic thesis based on information about the clubs and interviews. The purpose is to study the basic variables for pricing of tickets in Swedish ice hockey. Furthermore the pricing itself and its connection to the new arenas are studied.The focus of the thesis is on the three clubs HV 71, Färjestads BK and Linköpings HC.
Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass
depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet
grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts.
Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance.
This literature has illuminated a major environmental problem and it has been suggested
optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a
definite answer for the optimal method for each site tests should be carried out, this because many
factors determine to what is suitable for each, specific environment.

Intelligent vattendesign : utformning av Gjutarplan i Kallhälls centrum
The thesis aims to be an informative study for landscape architects and hopes to contributeto an understanding of ways water can be used and managed at sites lacking open, greensurfaces.The title "intelligent water design" should evoke the reader?s thoughts concerning intelligentaspects of water. Text, images and the design proposition give hints about these aspects.In the first part of this thesis, various examples of water design are presented. The chosenexamples are all applicable in urban environments with a high percentage of impervioussurfaces.The second part examines Gjutarplan, an urban square in the centre of Kallhäll, in Järfälla,north of Stockholm. Gjutarplan is first framed in a geographical and historical context.
Utställd Frihet - En studie av hur ägandeformen påverkar friheten inom två konstnärliga organisationer
The aim of this thesis is to study how the form of ownership affects the freedom within an artistic organization such as a museum or an art gallery. I have compared a publicly owned organization, Moderna Museet, with a privately owned organization, Magasin 3. The study is limited to only investigating the area of exhibition activities. A qualitative method has been chosen, and the empirics have mainly been collected through semi-structured interviews.The result shows that the form of ownership affects the freedom. Overall, one can conclude that the missions of the organizations look different, where the privately owned organization is given a greater freedom within their mission than the publicly owned organization.
Utvärdering av ett värmepumpsystems prestanda till en HWC-tvättmaskin : Med fokus på fläktvarvtal och köldmedieflöde
This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.
I hamn : - En fallstudie av det privatoffentliga partnerskapet Vänerhamn
This study focuses upon the new societal objects that are termed public privatepartnerships where the public sector forms strategic alliances with the private sectorand the civil society to manage the wicked issues of today. An exampel of suchcooperation is Vänerhamn AB where the municipalities around the lake of Vänernand the private shipping companies got togheter to handle an economic crisis of theshipping buisiness. The partnership Vänerhamn has developed from a problematicactivity to a healthy company and the aim of this thesis is to illuminate thisdevelopment through an historical institutional approach, focusing critical junctureto discover if the governance theory can be used to understand the partnershipspositive process. This will be done through research questions about the organisation of thepartnership, about the members interests with the partnership and about eventuallycoordination problems in the partnership. The questions derive from dimensions ingovernance theory, central for the activity of partnerships. Interviews with centralinformants where held and it was complemented through a document analyses inorder to search for indications of the dimensions and that is the methodologicalapproach of the study. The conclusion of this thesis is that the governance theory can be used tounderstand Vänerhamns postive development since the members interest with thepartnership to a begining was not at all conformed and that led to obviouscoordination problems.
Implementeringen av EU:s ramdirektivför vatten i kommunernas planarbete : En studie av kommunerna i Stockholms län
The European Water Framework Directive (WFD; 2000/60/EC) was incorporated into the Swedish legislation in 2004 through the ordinance Förordningen om förvaltningenav kvaliteten på vattenmiljön (SFS 2004:660). The objective is that all water bodies shall reach a good status by the year 2015. In Sweden the comprehensive plans of the municipalities can play a large role in reaching these goals. A comprehensive plan deals with the long term water and land use of the municipality, which can facilitate an early consideration of water management in the planning process of the municipality. In Sweden five river basin districts have been established in accordance with the Water Framework Directive.
Ledarskapsskillnader mellan ofentligt och privat anställda ledare : När sektorstillhörighet inte längre är relevant
The Public vs. private movement has over the past decades identified numerous significant differences between public and private organizations. The observed differences covers almost every field in administrative economics ranging from organizational structure, management accounting, goal-setting and in the past few years even leadership. Strangely, in the majority of these studies little or no regards are given to organizational characteristics or fundamental differences between compared organizations and if these organizations really are comparable when studying the effect of sector.The aim of this study is to compare leadership in relatively similar organizations from both the public and private sector and so clarify if earlier identified differences in leadership styles still surface when leaders working with approximately the same thing in a similar work context are studied.A sample of 348 Swedish principals was drawn from both municipal and private elementary schools. The respondents answered a web-based survey based on the CPE-model resulting in leadership styles mapped according to three orientations: change, production and employee.
Näringsbelastning på en anlagd våtmark från åker, skog och enskilda avlopp :
This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).

?Man behöver inte folks nummer längre? : En studie om hur studenter använder meddelandekommunikation via smartphones
How do young adult students communicate through their smartphones today? Which applications and features do they choose? What motivates their choices for the various possible situations? In this paper we investigate which communication channels young adult students in Sweden use for private message communication in their smartphones, in what way they use the channels and why they choose specific channels for different types of communication. In Sweden today, there are numerous of different ways of communicate through smartphones. We have interviewed ten Swedish young adult students regarding their use. The results speaks for that SMS has proven to still be used very frequently, even though it has existed for many years and that there are plenty of other ways to communicate through private messages today.
En utredning om effekterna av Skogsstyrelsens röjningsrådgivning
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.
Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud
The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.
