Termoelektrisk lagring i system med fjärrvärmeproduktion
With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.
Det smarta kapitalet : En studie av nyetablerade IT-företags syn på relationen till sitt riskkapitalbolag
Background: The growth of the venture capital industry has given birth to new relations between investors and entrepreneurial firms. Venture capital firms are by definition investors serving as an active partner which implies a deeper relation between investors and entrepreneurs than has been the case previously. This new situation leads to a number of questions. Do venture capitalists really act as active partners with a long term interest in the venture? Do they add any value besides capital? How important is their influence in the portfolio company's decision making process? Purpose: The purpose of this study is to give a deeper understanding of the relation between venture capital firms and IT companies in the start-up phase.
Skolbiblioteksmodeller: en studie i två kommuners sätt att organisera skolbiblioteksverksamhet
Our purpose with this master thesis is to look at school libraries in two separate municipal contexts and with the help of case studies try to reach understanding of how the municipal organisation in general influences and co-operates with day to day reality. In order to achieve this objective we have posed the following questions: What importance are school libraries given in relation to questions of overall management and goals in the greater organisation? How are resources distributed and management allocated in the two cases? How are the various school libraries in the two municipalities organised when it comes to workload, employee role assumption and teamwork? In the section dealing with theory and previous research we present the theoretical viewpoint and the literature of importance for our subject. This includes a short history, reports and laws, and also some research and theory on school library organisation. Our method has been to study the circumstances in two separate municipalities, Varberg and Växjö.
Solenergisystem i Kista Galleria
Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.
INDIVIDUELL LÖNESÄTTNING Från policy till praktik ? en fallstudie på Sahlgrenska Universitetssjukhus
I större organisationer finns ett behov av att säkerställa att organisationens olika verksamheter arbetar efter samma lönestrategi och mot samma mål, samtidigt som lokala verksamheter måste anpassa direktiv och policys som förs ner genom organisationen till sin kontext. Syftet med studien är att genom en fallstudie skapa en förståelse för hur individuell lön praktiseras och organiseras inom en stor offentlig verksamhet samt skapa en djupare förståelse för kopplingen mellan policy, strategi och lönesättning. Organisationen som studeras är Sahlgrenska Universitetssjukhus och HR-avdelningen centralt på Västra Götalandsregionen.Studien har genomförts med en kvalitativ metod. Det empiriska materialet utgörs av fem semistrukturerade intervjuer med lönesättande chefer och två fokusgruppsintervjuer med HR- medarbetare. Intervjuerna har transkriberats och analyserats med tematisk analysmetod och empirin har kopplats till teori och tidigare forskning.Studien fann att en av de huvudsakliga avsikterna med lönepolitiken i organisationen var att motivera medarbetarna, men att det bland respondenterna fanns en varierad syn på sambandet mellan lönesättning och motivation.

Metodutveckling för planering och genomförande av dikesrensning med moderna metoder
?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes.
In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests.
So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland.
We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning.
A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests.
This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.
Implementering av miljökvalitetsmål i mindre kommuner : - En fallstudie av Torsby kommuns arbete med att implementera delmålet Planeringsunderlag
The aim of this dissertation is to examine why smaller municipalities[1] in Sweden experience difficulties when implementing the 16 environmental objectives that are designed to solve Sweden's environmental problems.The theoretical framework used for this dissertation is implementation theory which provides three conditions that need to be met in order to have a successful implementation. These three conditions have shaped the research questions that examine if Torsby municipality has the "understanding," "ability" and "will" needed to implement the decision correctly. The dissertation employs a case study method to examine why Torsby municipality has experienced difficulties implementating the target: programmes and strategies for planning, which is an interim target to environmental objective number 15: A good built environment. Qualitative text analysis and interviews with politicians and civil servants from Torsby municipality and the county administration board of Värmland have been conducted in order to answer the research questions. The material used for this dissertation is mostly from the government bills that are the foundation of the Swedish environmental policy and the documents and reports about the environmental objectives that the National Board of Housing, Building and Planning (Boverket), the Swedish Environmental protection agency (Naturvårdsverket), and the Environmental objectives council (Miljörådet) have released.The result of this dissertation supports previous research which has shown that smaller municipalities have problems implementating the environmental objectives due to a lack of financial resources. This dissertation also shows that the problems can be due to a lack of understanding the purpose of the objectives. This leads to a lack of political will to implement the objectives. Since the municipalities do not have the political will to implement the objectives the appropriate resources needed for a successful implementation are not appointed and therefore the municipalities are not able to fully implement the environmental objectives. [1] Municipalities with less than 20 000 inhabitants..
Koldioxidsutsläppsbesparing vid biogasproduktion
Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.
Hållbarhetsredovisning i Kommunal Verksamhet : En kvalitativ studie av fem kommuner i Skaraborg
In today's society it has become increasingly important for organizations to take into account non-financial values. Sustainability reporting involves reporting the economic, social and environmental aspects of an organization's operations. The trend has been towards an all the more scrutinizing society with an increasing demand for transparency and translucency. A greater focus on environmental issues has also contributed to sustainability?s increasing importance as a topic.
Alternativa Drivmedel som Enhetsdrivmedel
Fossila drivmedel står idag för en överlägsen majoritet av den totala användningen av drivmedel som dagligen förburkas. Alternativ till de fossila drivmedlen krävs för att säkerställa tillgång i framtiden. Försvarsmakten har fått uppdrag från regeringen att utforska möjligheten att övergå till att driva sina fordon på förnyelsebara bränslen.Militära organisationer strävar efter ett enhetsdrivmedel, alltså ett gemensamt drivmedel som driver samtliga fordon och enheter. Största anledningen är den förenklade logistik som kan uppnås om endast ett drivmedel används.Detta arbete har sökt efter ett alternativt drivmedel som skulle kunna användas som enhetsdrivmedel inom Försvarsmakten. Detta för att lösa problematiken med att både byta till ett förnyelsebart drivmedel och ett enhetsdrivmedel i samma fas.Slutsatserna som dragit i detta arbete är att FT-bränslen har potential att användas som enhetsdrivmedel ur ett tekniskt perspektiv.
Hjälpguider: en diskursanalytisk ansats
The empirical data used for this master thesis, consists of eight manuals with the main purpose to help students evaluate information resources found on the web or Internet. The purpose is to elucidate the discourses and investigate those textual characteristics, which figure in the investigated manuals. The method used is a discursive and linguistic approach, with a power/knowledge discussion applied to the results. The analysis identifies, among other things, the production and consumption of the investigated texts, and that the manuals function as a reflection of the relationship between the participants in the situation, the sociocultural practice of the institution and its identity..
Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat
People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.

Grovkrossning av stubbar : en produktivitetsstudie
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.
