Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

The development of farm-operated biogas plants in Sweden is increasing. This study investigates the process that firms go through in developing such ventures. The aim is to identify obstacles and opportunities that individual farmers have encountered during the implementation process, and through a comparative analysis find similarities and differences between cases. The overall goal is to increase understanding of the factors that influence farmers? development of farm-based biogas production, and more specifically, explore opportunities for support organizations to contribute to the innovation process. Findings indicate that the implementation process has changed over time.

Skanska 21 is a student program for university students. The program runs for a year and a half parallel to university studies. It is aimed at those studying a few specific master engineering programs at Lund University, Royal Institute of Technology (KTH), Chalmers University of Technology or Luleå University of Technology. The program consists of a number of program meetings such as company presentations, a boarding school week, rhetoric training and project visits. The aim of the project is to evaluate the Skanska 21 student program.

The main purpose of this study is to examine differences and similarities concerning teamwork and interactive skills among preschool children while they interact with an Ipad respective a number of selected traditional artifacts. The traditional artifacts chosen for this study are small Lego blocks, JovoToys (click and construct system) and large puzzles. The study takes its starting point on the basis of both a social- and a learning perspective when different groups of preschool children in the ages from three to five years interact in fellowship groups with respective artifact. Primarily the main focus is to examine differences and similarities that appear from without the social perspective.The overall objective is to identify what eventual differences and similarities can be found purposely on both what is happening in the social interaction between the preschool children themselves but also what is taking place in the interaction between the children and each artifact. This study will also via theoretical frameworks create an understanding why eventual differences and similarities exist.The results are based on both a literature review and a field study.

The study was conducted in Jönköping County Chamber of fibrillation and is about change and improvement of process modeling technology. The process for treating patients with fibrillation is in the need to evolve and improve. In order to develop the care they needed a current state description which usually is made with the traditional process modeling tool.Many scientists and health professionals is in the opinion that this technology gives a too rigid image to describe the care processes. It also does not sufficiently take into account the human aspects. This reasoning suggests that the process modeling technology in healthcare is in the need to develop multiple perspectives.

This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a medium ? has acquired an ambiguous importance.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.

The purpose of this article is to investigate how and from which sources librarians collect information on their profession with respect to factors that are important for their work. In order to achieve this goal, a questionnaire-based survey will be conducted at three medium-sized central-public-libraries in southern Sweden. Using this survey, I wish to answer the following four questions: To what extent do librarians acquaint themselves with changes and developments within regional and cultural policy arenas important to their work? To what extent do librarians acquaint themselves with information using conferences and library debates that are focussed on changes and developments relevant to their work? Do librarians consider that they have enough time within the limits of their work hours to follow developments within the librarian profession, for example with respect to developments within information technology, and how would they appraise the future demand for information technology-based services at the library? From which source(s) do librarians collect information relevant to their work? The theoretical basis of this paper can be compared to a radar as it scans subjects-of-interest to the organization in the field of business intelligence. This investigation uses a quantitative method, with data collected via a survey consisting of 13 questions.

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Today?s society is very focused around technology and something that is very popular is the usage of mobile devices such as Smartphones or Tablet computers. One of the reasons why these devices are so popular, is because of the large amounts of services or ?apps? that they can provide for the user. They can do a lot of things that makes everyday living easier for the users.The focus of this study is to find out what kinds of mobile services the users of these devices are expecting and/or wishes to see in the future and what is required to be able to develop and use these services in a good way.We started of the study by searching for earlier studies on the same or similar subjects.
