Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity. Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.

The essay aimed to investigate whether people choose light products or original products regarding dairy products and beverages as well as the motives for their respective choice. Finally the purpose was to find out where they had obtained the knowledge to make their choice and how they thought media had affected their choice. The method used was a qualitative decsriptive study with three focus groups consisting of six women aged 40-50, six women aged 20-30 and four men aged 25-35. Each interview lasted 2 hours. The groups were a selection of comfort.   The results showed that all respondents choose original products. The primary reason was because they thought that original products tasted better and had a better consistence.

The purpose of my project is to determine how a multimodal/intermedial text can be used when teaching in upper secondary school. Can using a text that to some point is current in the pupils? lives lift the interest for the specific subject? I opted to pick up Gunther Kress? research, Diana Laurillard?s book and Christina Olin-Scheller?s work on the subject. I have used several hours of lesson planning and the lesson itself with subsequent work consisting, among other things, of three qualitative interviews to achieve my purpose. Based on a qualitative approach, I discuss the results, which show that it is in fact very uplifting.

The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.

This essay tries to investigate the possibility to reconstruct the concept of mimesis in Martin Heidegger?s hermeneutical phenomenology in Sein und Zeit. Paul Ricoeur?s interpretation of the concept of mimesis in Aristotle?s Poetics, develops a new temporal understanding of the mimetic activity, which Ricoeur in his work Time and Narrative, claims to have the possibility to overcome the aporias in the phenomenology of time. With this criticism as the background context for the present study, seeks this essay to pick up Ricoeur?s new conception of mimesis, and use that in a comparative philosophical reflection on the basic concepts in Heidegger?s Sein und Zeit.

Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity. In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.

When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important. In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment. After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs. Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Swedish beef production has during the past year decreased while the consumption has increased. It´s imported beef that takes market shares. The purpose with this degreeproject is to investigate if the restaurants in Sweden are using imported or Swedish beef and the reason for their choice. The purpose is to find out if there is something the Swedish beef producers can change to increase Swedish beef in restaurants. My expectation is that the demand for Swedish beef will increase in restaurant and later even among consumers. I have interviewed ten chiefs in different restaurants and asked them the following questions: Is it the price, quality or something else that influences your choise? Does it matter to their customers if they serve Swedish or imported beef? How is the marketing of Swedish beef? It appeared both Swedish and imported beef on the restaurants.

The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.

A major part of the Swedish population suffers from myocardial infarction. A wish in the study is to give nurses an increasing knowledge about what patients with myocardial infarction wish to be informed about so that the nurses can meet these patients as good as possible.The aim is to show what nurses need to inform heart patients about to prevent anxiety and fear after hospital care.The method used was literature reviews where seven articles were reviewed according to Polit, et. al., (2001). The databases used were Cinahl and ELIN.Results: There is a dissonance between what the patient and what the nurse is ranking to be the most important item to be informed about after a myocardial infarction. The patients prioritize information about symptoms and lifestylechanges.

Deliberative democracy theory holds that democracy is about active partaking on formal and informal arenas in the public sphere where fairly equal citizens can obtain knowledge, discuss, evaluate and affect the political agenda before decisions are made.In line with the deliberative vision of online deliberation social media such as Facebook, Youtube, Twitter and Twingly offer such formal and informal arenas where people can obtain knowledge and interact with other people, and politicians.The Swedish EU-Presidency was the first EU-presidency to make use of social media and it was the first time the Swedish Government Offices used other social media than email and chat features.This thesis will examine the Swedish EU-Presidency?s ambitions of using social media as well as the actual use of social media on the Swedish EU-Presidency website in the light of deliberative democracy theory.The aim of this thesis is, through a case study, to analyze the Swedish EU-Presidency?s use of social media in the light of deliberative democracy theory..
