Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Research on the power of customer involvement, and in particular recommendation is very resourceful. Many studies have mapped the reasons for why customers are willing to recommend, however they often ignore potential differences among brands and how that may affect these reasons. This study is built on a quantitative survey investigating how consumers interact with brands, depending on category affiliation. The categories used were Bhat and Reddy's symbolic and functional, consisting of three brands respectively where each brand represented a different product type.The evolvement of social media has also transformed the platform of recommendation from physical to virtual and changed the way people connect. Thus, taking the investigation further, potential differences between symbolic and functional brands was tested in different social media platforms.

The aim of this Master's thesis is to explore how the localisation and the design affect the conditions for a school-media centre. A school-media centre is in this study a place where the students seek, find and evaluate information, discuss and exchange ideas. An active place for generating knowledge. The method applied in this study is "Space Syntax Analysis", a quantitative method with visual representation of the results. In the theoretical framework, space is the voids between walls, doors and ceiling, between furniture and bookshelves.

For the last ten years Internet has become more popular and is now used by most Swedes every day.  Internet has made it possible for many people to access a great deal of information about news all day long. Internet has also made it possible for people to create their own news and comment on happenings as they are taking place. One way to do this is to start your own blog, which is a kind of diary where you can publish your own thoughts about politics and news.In Sweden the media is often referred to as the third governmental power since the media is examining the government and people in power positions and bringing the people as consumers of news closer to the government. There is a theory called agenda setting that says that the media is an actor that shapes the political issues discussed by the people and politicians.In this essay I have used the agenda setting theory and linked it together with the Medias references to blogs in their news. This I have done to see if the media might be influenced by blogs.

This paper is about our collective fascination for the social medium Instagram, and our lively discussions about why certain images may be more so-called "Liked" than others and why some individuals becomes more successfull on Instagram than others.

With social media new ways to construct and communicate images have appeared. Artists, celebrities and companies use media as a channel for communication and marketing. In our study, we focus on the use of Instagram for marketing purposes by Rachel Brathen, one of the worlds most well-known yogainstructors.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

The main purpose of this essay is to investigate the legal position for employers concerning protection against what employees can express about one?s employer in social media.It may regard dissatisfaction concerning employment, tort or so-called whistleblowing. The spread through social media may be comprehensive and thus cause more damage to the employer.Employees within the public sector as well as in the private are protected by the liberty of speech, which is constitutional, even the protection of sources or the right to criticize can offer some protection. This gives the employees the possibility to widely express themselves in private social media as long as it can?t be classified as a violation, which per se is very rare.However, certain differences between the both sectors will be pointed out.There are still no constitutional rights regarding social media, but a grey area has emerged concerning the legal position.

We have studied the effects that blogs have on the society through interviews with influential bloggers, a news director and the founder of Sweden?s largest blogprovider.Existing theoretical work by other researchers have been used as a starting point to our thesis. Via a deductive method we then proceeded to test these existing models and viewpoints on the reality.Through our research we have concluded that blogs, if they co-operate, have an agenda-setting function, and that they can affect newspapers to write about certain topics.We have also discussed blogs role as media watch dogs. Gunilla Sax, news director, questions the blog world?s ability to fully cover all media, and to deliver a systematic and just review of the media.

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.
