Solvärme för en skola i Lerum. Studier av olika systemalternativ.
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
"Periodare" hos socialtjänsten? : En undersökning om unga vuxnas behov av försörjningsstöd
The purpose of this study is to find out how social workers in one medium and one smallmunicipality in central Sweden perceive the need of financial support for young adults formore than one year and what the causes might be. To answer our research questions aqualitative research method was used and four social workers were interviewed. The resulthas been analyzed based of social exclusion, stigma, as well as on structural and individuallevel and linked to previous research. Our results show that although young adults are anexception for long duration for financial support, there are those who lack other means ofsupport for a long time. The results also show that young adults often are recurring in thesocial services, and they are long-lasting.
Organisationskultur ur säkerhetsperspektiv ? en fallstudie utifrån Cultural Theory
The aim of this master?s thesis is to identify differences and similarities, regarding security, in two goods terminals in an organisation in the transport and goods sector. In this thesis we use Cultural Theory as an analytical instrument to investigate organizational culture, as seen from a security perspective. Cultural Theory is a theory seen from two perspectives, the stable perspective and the mobile perspective. These two perspectives concentrate on different research areas.
Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Termisk Vattenpump
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.
Säkerhetsservice/Fixartjänst En fallstudie om en implementeringsprocess som befäster de klassiska könsrollerna
Fighting against accidents with elderly involved have come to be one of the west world's greatest challenges together with the climate changes and epidemics, and in order to fight against these accidents SDF Centre, Gothenburg appointed a man to the post as a caretaker.The aim of this master thesis is to analyse whether the implementation process and the systematic work correspond with Vedungs implementation theory and also put forward arguments for and against a masculine entrance into promotion old-age care; if it strengthens or is a take-off from the classical sexual roles.The thesis main theory is Evert Vedungs theory of implementation, which is constituted of eight factors which facilitates an implementation process. In order to theorise the sexual roles I have appropriated a gender perspective, constituted of multiple researchers and authors.The conclusion I have received through the qualitative interviews carried out with actors involved in the implementation process, is that the security services implementation correspond well with Vedungs implementation theory, hence the implementation has proceeded efficiently. The classical sexual roles is on one hand strengthened through a masculine possession of the security service, and on the other hand can the masculine entrance in the old-age care entail that more men apply for promotion old-age care work..
Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
Låst läge? : En fallstudie om ledarskap, kommunikation, relationer och invävnad mellan Assa AB och Assa Abloy Romania
1998 förvärvades företaget Urbis Security i Rumänien. Urbis Security blev sedermera införlivat i dotterbolaget Assa Abloy Romania. Med tiden har problem börjat dyka upp och företaget har fått allt svårare att hävda sig både kvalitets, konkurrens och resultatmässigt. Följden av detta är planer på nedläggning eller förflyttning av vissa delar i tillvekningsenheten av Assa Abloy Romania. Undersökningens syfte är att med hjälp av den framtagna modellens fyra faktorer utvärdera hur dessa påverkade situationen fram till nedskärningarna av vissa delar inom tillverkningsenheten i Assa Abloy Romania.
Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö
In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely.
The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished
the result is graded in the following categories: economy, environment and quality.
To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.
Solenergi i Norrra Djurgårdsstaden
This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.
Bygglovsbefriad vindkraft till småhuset : -Ur ett tekniskt och ekonomiskt perspektiv
In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

Översyn av uppvärmning
The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.
