When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

This study has examined how social media has changed food companies way of holding contests. The study examines how food companies use contests with the help of social media and how they used to do the contests before the use of social media. We have also researched the users behaviours and opinions of companies contests on and outside of social media.In this study we have interviewed four people responsible for contests on the social media department on their respective food company. We also performed a survey that was published on Facebook and followed it up with interviews from two of the participants.This study has showed that contests on social media, as a technical aspect, have given new possibilities for the design of the contests. But there are still some unexplored areas around contests on Facebook and the companies do not know exactly what the users are demanding.

Studien har syftat till att undersöka samband mellan samsjuklig psykologisk problematik och katastroftänkande hos ungdomar utifrån ett transdiagnostiskt perspektiv. Katastroftänkandets roll för förändring av social ångest och depressiva symtom undersöktes utifrån en studie av internetbaserad KBT-behandling mot social fobi (N=18).  Resultatet indikerar att ungdomar med hög initial nivå av katastroftänkande har större reduktion av depressiva symtom än ungdomar med låg nivå av katastroftänkande. Detta talar för att hänsyn bör tas till grad av katastroftänkande vid utformning av behandling för personer med social fobi, särskilt vid samsjuklighet med depression. Kopplingen mellan katastroftänkande och samsjuklighet undersöktes utifrån en tvärsnittsstudie av gymnasieungdomar (N=713).  Resultatet visar på en koppling mellan katastroftänkande och social rädsla, sömnproblematik och nedstämdhet..

The purpose of the study was to examine what possibilities and obstacles, according to the personnel and patients in a methadone treatment, exist in the patient's social rehabilitation. How does the methadone treatment encourage the patient's social rehabilitation, what possibilities/obstacles are there according to personnel and patients? What does the patient see as important aspects of his/her social rehabilitation and what importance does the methadone have on the treatment? The results show that there are difficulties for patients to rebuild their life, find employment, start new social networks and get by with everyday tasks. The support from friends and family will simplify the patient's social rehabilitation, otherwise they get isolated and alone. Patients feel that they are fighting for a successful treatment so that they can have a relationship with friends and families again.

This paper describes how files and information can be shared in organisations and workplaces. We studied and compared the traditional file sharing in Microsoft Active Directory and the Social file sharing that comes with Microsoft SharePoint Sites. We used qualitative studies based on interviews with system administrators, management and by our own observations to acquire the necessary data. Using independent research, we were able to analyze the data and show the general difference between the traditional and the social file sharing systems. Social file sharing enables the user to easily store and share files in a flexible online environment.

    The purpose of this essay is to examine trust, or lack of trust, in the social services. Previous research considering this topic is limited, which, in our point of view, implies the need of further studies. A quantative method was used, consisting of an online questionnaire containing statements about the social services. The statements were designed using a five level Likert-scale which required the respondent to rate their level of agreement. The questionnaire was published on five webcommunities directed to parents.

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.

The purpose of this paper was to examine social workers' experiences of integration of unaccompanied children. We aimed to study which factors in the individual and the community social workers experience affect the integration and how they, based on their understanding, work to promote integration. The essay has a phenomenological approach and focuses on the social workers' own experiences of the phenomenon. The empirical data was obtained from qualitative interviews conducted with five social workers, all administrators in cases involving unaccompanied children. The result shows that the social workers feel that the desire to integrate is the most important presumption that must be present in the unaccompanied children.
