Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Dubbelklicka på Emil - en studie av arbetet med CD-romspel med litterära förebilder på några folkbiblioteks barnavdelningar
The technical evolution has a great influence on the public libraries. Electronic media becomes more and more common. This Master´s thesis is based upon the Swedish Library law 9§ (SFS 1996:1596) which says: Public- and school libraries should pay special attention to children and teenagers by offering books, information technology and other media, adapted to their needs, to encourage development of language and stimulate reading. From this point of view we have examined why the children´s departments in public libraries offer CD-ROM games which are based upon characters from the literature, how they are used in the daily activity and how they can contribute to the development of the children´s department.We have made literary studies and empirical investigations including interviews, observation studies etc. The results from this studies shows that both young and adults appreciate the CD-ROM games.
INVOXICATED. En interaktiv lek med ljud
Invoxicated is an interactive play sculpture where children can explore the wonderful and playful opportunities of sound. Talk into one end of the sculpture, and the sound will travel through the sculpture and come out in the other end. On its way, the sound gets distorted by a number of sound effects. By bending the sculpture?s body, and pressing the sculpture?s buttons, the sound effects gets altered in real time.

Bakomliggande motiv, alla har dem : En kvalitativ fallstudie om varför kunder sprider e-WOM på sociala medier
Kurs/nivå: 2FE16E, KandidatuppsatsFörfattare: Martin Alm, Anton Bengtsson, Pär IvarssonHandledare: Dan HalvarssonExaminator: Åsa DevineTitel: Bakomliggande motiv, alla har dem.Nyckelord: e-WOM, electronic word-of-mouth, e-wom motiv, sociala medier, Facebook. Bakgrund: Att veta varför kunder delar med sig och sprider information om företag har blivit viktigt för företag om de vill effektivisera sin marknadsföring på Internet. Mycket av den tidigare forskningen gällande e-WOM har fokuserat på informationsspridningens effekt men inte vad kunder har för bakomliggande motiv till att sprida e- WOM. Forskning har också visat att det finns skillnader i hur kunder sprider e-WOM på sociala medier jämfört med övriga plattformar på Internet. Det är därmed betydelsefullt att på ett djupgående sätt utforska vad kunder, utifrån deras perspektiv, har för bakomliggande motiv till att sprida information om företag på sociala medier. Forskningsfråga: Varför sprider kunder e-WOM på sociala medier?Syfte: Syftet är att utforska kunders bakomliggande motiv till spridning av e-WOM på sociala medier. Metod: Utförd som en fallstudie av ett enda fall genom sex stycken semi-strukturerade intervjuer. Slutsats: Undersökningen visade att det finns 15 bakomliggande motiv till kunders spridning av e-WOM på sociala medier.

En jämförelse av RDF och avfall som förbränningsbränsle
In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.
Att vara i en intensivvårdsmiljö : patientens perspektiv
The Intensive Care Unit (ICU) is a special unit for patients who is in the need for emergency life-sustaining measures and every patient has complex medical- technical equipment. The experiences of a critical illness and the needs of critical care are experienced in different ways. The purpose of this study was to describe the experiences from patients in the ICU and how this experience has an influence on the patients. The method was a study of literature with a qualitative inception based on eight scientific articles and the analysis of content has been inspired by Graneheim and Lundman (2003). The result of the study is presented by four categories: to loose the ability to make themselves understood, to be forced to adjust to the environment of caring, to have the lack of connection with reality and to be in an intensive care environment, The results showed that patients in the ICU are affected by the attitude from the staff, the equipment around them as well as the sounds and lights in the environment there.
