Solmodul jord- och bergvärmepump
An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.
Revisorernas dilemma - tala eller tiga?
Since 1999 auditors have an obligation, according to 42-44 §§ aktiebolagslagen (2005:551), to report suspicions of crime. The obligation to report means that the auditor is legally obliged to report any suspicious economical crime potentially committed by the executive director or a member of the board to a district attorney. Prior to the enactment it was almost impossible for the auditor to report any criminal suspicion due to the professional confidentiality. According to Ekobrottsmyndigheten the number of crime suspicion reports filed by auditors has reduced by 50 percent in the Stockholm-region between 2006 and 2010. However, after the enactment crime suspicion reports increased successively each year.

Höjdförändringar på Lomonosovfonna, Svalbard, 1996-2012
The climate changes and the global warming have a great impact on the Arctic environments. This partially depends on that the albedo is getting lower when snow and ice is melting and exposes more and more dark surfaces of the land and sea. This leads to a feedback effect; the melting accelerates because dark surfaces attract more sun radiation. Because of the heating the glaciers in Arctic retreat. The purpose of this report is to obtain an eventual change in elevation on the glacier Lomonosovfonna that is located on Svalbard by comparing elevation data collected by NASA and GPS data from 1996-2012.
Distriktssköterskans erfarenhet av att bedriva stödjande insatser vid en hypertonimottagning : En pilotstudie
Hypertoni beskrivs vara en riskfaktor bland annat för hjärtkärlsjukdomar som tenderar att öka och patienter med hypertoni når i allt större utsträckning inte behandlingsmålen enligt Socialstyrelsens nationella riktlinjer. Tidigare studier har visat att distriktssköterskeledda hypertonimottagningar med strukturerade strategier har haft positiv effekt för patienter med hypertoni, men inte beskrivit vilka stödjande insatser som distriktssköterskorna utför. Syftet var att beskriva distriktssköterskans erfarenhet av att bedriva stödjande insatser vid en hypertonimottagning inom primärvården. Urvalet bestod av fyra distriktssköterskor som bedrev hypertonimottagning i primärvården. Materialet till pilotstudien samlades in via intervjuer.
Kvarboendeprincipen i äldreomsorgen
This essay aims to examine and compare the attitudes of decision makers in the local government and representatives of pensioners in two different geographic areas. The main questions were:- their attitudes towards the "stay home principle" (kvarboendeprincipen, a principle that aims to make it possible for people with a handicap, disease or age to stay in their homes instead of moving to nursing homes).- their attitudes towards nursing homes for old people- their attitudes towards the possibility of staying at home when you are old and handicapped and in need of care.The essay is built on qualitative research methods, based on interviews and on a review of research in the field.The author found a complex picture of attitudes. Everybody thinks that the best is to live in your own home as long as possible, except from those who live with Alzheimer´s disease. They showed different opinions on the issue of the need for moving to nursing homes. This might result in forcing people to stay at home.
Integrationspolitik i praktiken : En utvärderande fallstudie av Storstadssatsningen på Bergsjöns bibliotek
The purpose of this Master thesis is to increase the knowledge about how public libraries can contribute to fulfil political programmes aimed towards integration. To achieve this we have conducted an evaluative case study about a public library in Sweden and the activities they carried out within the framework of the metropolitan policy programme Storstadssatsningen?. The questions raised consider which the political aims for integration within this programme were, which activities the library did accomplish, what the result in comparison with the politically decided aims was, and what conclusions can possibly be drawn from this? The theoretical framework consists of theories regarding evaluation, political programmes, integration and segregation, and public library-activities.

Vårdgivaren har ett ansvar att leda patienten till tillförlitliga informationskällor. Syfte: Syftet med studien var att belysa distriktssköterskors erfarenheter av att patienter söker hälsoinformation på internet och hur det påverkar deras arbete.
Äldre invandrare och den offentliga äldreomsorgen - bistånd, behov och särskildhet
The purpose of this study is to investigate whether an increasing amount of elderly immigrants will set new demands upon the public eldercare. The focus is on the officials whithin the public care of elderly in Västra Götaland district, and their experiences. A second purpose of this study is to add the experiences of the officials to former research treating the topic of elderly immigrants and their experiences of the public eldercare in Sweden.The survey has been carried out through interviewing all together seven officials working within the public care of elder in varying districts of Västra Götaland. The interviews have later been summoned under four different themes such as, ?Culture, customs and tradition?, ?Interaction and communication?, ?Information? and ?The future of the public eldercare?.The study indicates that our result based on the interviews, is in several references corresponding to former research on the topic.
Dubbla uppdrag : En kvalitativ studie av två profilerade och integrerade folk- och skolbibliotek
The aim of this master?s thesis is to examine libraries which combine the functions of school- and public library and to evaluate the staff?s experience and attitude towards a library profile with the emphasis on children and youth. The purpose of the study is also to examine how the libraries work with several tasks and functions within different target groups with different needs.With new institutionalism and Scandinavian institutional theory the thesis examine the library as an organization and what influences the construction. With a model that describes how the library constitutes four different rooms in the society I investigate the different functions.The methodology is qualitative with interviews of five persons of the staff, four librarians and one library assistant. The study examines how the staff that works at two libraries under similar conditions experiences their tasks.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
Biogas på Wapnö : Analys av framtida energisystem
Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.
Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer
This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.
