Den kontrollerade tekniken : En studie om de exklusiva Plymouthbrödernas förhållande till samtida teknik
The purpose of this thesis is to examine the Swedish Plymouth brethren?s relation to contemporary technology. What types of technology are considered acceptable and where do they draw the line? Due to the brethren?s separation from the parts of the world they believe leads people away from God, such as the entertainment industry, immoralities etc., they reject use of television and radio. These two are viewed as uncontrolled types of technology since the user does not have control of its contents.

Dubbelkönighet hos mört : normalt eller miljöinducerat?
A number of chemical agents, and their degradation products, have been
recognized as having estrogenic activity on animals. On fish they interfere with
endogenous estrogen and in many cases mimic its activity, thus increase estrogenic
reponse, with elevated levels of vitellogenin. Hence they are called Endocrine
Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of
exposure to estrogenic pollutants. Wastewater from sewage treatment works
contains chemicals known as EDCs, and there are evidence of roach (Rutilus
rutilus) living in recipients of such wastewater having traits of both gender, i.e.
oocytes in male gonads (intersex) on histological examination.
This study was done on roach living in Lake Funbosjön Uppland, Sweden.
Biologisk reducering av nitrat och nitrit i vatten
During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.

Att öka livskvalitet genom mobile assistive technologies. En studie om hur rehabilitering- och habiliteringsverksamheter bör förhålla sig till mobile assistive technologies i syfte att öka livskvalitet för personer med nedsatt synförmåga
As the use of smartphones and other mobile technology in our society is constantly increasing,so too does the possibilities of visually impaired persons increase as they are becoming moreable to enhance their quality of life with the help of mobile assistive technology. The purposeof this study was to explore how rehabilitation and habilitation organizations, which areworking with the visually impaired, should approach new technology. We have researched thisby examining the possibilities, opportunities and barriers of using mobile assistive technology.Based on this, we formulated the following research question: What factors are important forrehabilitation and habilitation organizations to consider in order to support, promote andcreate quality of life through the use of mobile assistive technology in their work with thevisually impaired? To answer the above question an exploratory study was made at an eyeclinic in the Västra Götaland region. The study was done through a series of qualitativeinterviews with both staff and patients at the eye clinic.
Handelsbranschers användning av Augmented reality : En studie om dess möjligheter, utveckling och användning
Augmented reality is an interesting technology which has increased in popularity the last couple of years. Even though we see more and more of this technology the use of it doesn?t match up to its true potential. This paper aims to investigate the possibilities of this technology and illustrate how companies can use it in their business to reach out to customers in a new and exciting way. The study consists of three parts.
Commercialisation of inventions from a legal and business perspective
This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.
Hur påverkar ny teknik företags relation och kommunikation mot sina kunder och leverantörer?: En studie av fyra företags utnyttjande av moderna affärssystem och effekterna i kund- och leverantörsrelationerna.
This qualitative case study, made with four companies, looks closer at how more effective information management, with the help of IT-systems, affect companies market communication and relations to customers and suppliers. Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..
Utvärdering av avloppsvattenreningen vid Hallsta Pappersbruk : Kartläggning av inkommande avloppsvatten och optimering av driftparametrar
Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.
Tar vi barnens intresse för natur och teknik på allvar? : En kvalitativ studie om hur några förskollärare resonerar runt möjligheterna att ta tillvara barnens intresse för naturvetenskap och teknik i förskolan
The purpose of this study was to examine and compare what six preschool teachers thought about their opportunities to take advantage of children's interest in natural sciences and technology, across four kindergartens. The following questions were explored in order to achieve the aim of the study: How do the preschool teachers interviewed describe their work with science and technology in the preschool and what these preschool teachers think about the meaning of motivation in the children?s learning of natural sciences and technology in preschool. The study used a qualitative approach in the form of semi-structured interviews and interviewed a total of six trained pre-school teachers from four kindergartens with different profiles. The first kindergarten focuses on mathematics, science and technology.

IT-Instrument : En intervju-och observationsundersökning kring användandet av digitala instrument inom undervisningen i ämnena historia och engelska i en gymnasieskola
This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.
