Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

In the wake of a heightened interest in the Swedish Middle Ages, the need for knowledge has increased as well. The Swedish Middle Ages was an era when the country truly began to grow closer to the European sphere of culture. The forces behind this transformation are largely to be sought among the social elite, the budding aristocracy of Sweden. The process of becoming ?Europeans? brought with it great changes to Sweden, not the least in terms of the political arena.

This study concerns the energy future of the county of Stockholm up until 2050 and describes how the energy consumption can be compared to today with the use of scenario methodology. Within energy future studies the backcasting approach is well known and has been put to use in this study. Due to the characteristics of backcasting the study is self-fulfilling, i.e. the future energy scenarios presented in this study satisfy the targets set up in this study. In the light of what may be the largest challenge of our time ? the climate change - the aim of this study is to describe how the energy consumption in a fossil fuel free Stockholm county in the year of 2050 may be.

In my work I have received a lot of concrete advice about improving the cooperation between landscape architects and contractors. Here is a list of suggestions from both cathegories: Landscape architect's advice: ? Be humble, show respect. ? A practical approach makes cooperation easier. ? Call together a startup meeting with all the consultants and builders. ? Establish a network of contacts with serious contractors whom you can recommend to customers. ? Don't hesitate to ask the contractor for advice; they often have lots of useful knowledge. ? It is important to have clearly written and thoroughly worked out documentation. ? Never let a newly graduated landscape architect visit the buiding site without the company of an experienced colleague.

During whole-tree harvesting, there is a risk that the soil will become impoverished of nutrients. To prevent this, nutrients are returned to the harvested site as wood ash. This action also reduces the risk of soil acidification. Nevertheless, the ash does not result in any increase of tree growth if it is added on mineral soils, which is where the measure is most commonly used in Sweden. Due to the lack of growth response, the interest from landowners is small, which is why ash amendment today is not done enough to compensate for the need.

The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.

I denna uppsats har filmljudet i krigsfilmerna Apocalypse Now och Saving Private Ryan undersökts. Detta har gjorts för att försöka bidra med ökad förståelse för filmljudets användningsområde och funktioner, främst för filmerna i fråga, men även för krigsfilm rent generellt. Filmljud i denna kontext omfattar allt det ljud som finns i film, men utesluter dock all ickediegetisk musik. Båda filmerna har undersökts genom en audio-visuell analys. En sådan analys görs genom att detaljgranska båda filmernas ljud- och bildinnehåll var för sig, för att slutligen undersöka samma filmsekvens som helhet då ljudet och bilden satts ihop igen.

Policy document conversion in practice ? a qualitative study of five upper grade teachers approach to the 2011 policy documents in history.This essay examines five upper grade teachers approach to the new 2011 policy documents in the history school subject, as well as it?s impact on the teachers class room activities. Also, the study examines what factors have influenced this conversion process. Colleagues, the school management and the Swedish Skolverket (the Swedish school management organisation, controlled by the Swedish government) are in this study the main external influences that are studied. The study is carried out with an organisation theoretical approach, witch states that controlling the schools practical activities is hard, taking in to account a great variety of ?problems? that follow a teachers every day work.

Syftet med detta arbete är att undersöka ergonomins och hälsans förutsättningar på en processindustri i Sverige samt att ta fram förslag på förbättringar och ett träningsprogram för personalen på industrin. För att minska risken för belastningsskador är det viktigt att individen arbetar med ergonomiska arbetsställningar. Om arbetsgivaren förser arbetstagaren med så goda förutsättningar som möjligt att tillämpa ergonomiska arbetsställningar samt erbjuda friskvård kan kostnaderna för sjukfrånvaro sänkas betydligt. Metoder som använts är kortare observationer följt av de ergonomiska uträkningarna OWAS och RULA. En interventionsgrupp inom produktionen fick besvara en enkät, som även fylldes i av en kontrollgrupp som bestod av administrationspersonal (kontorspersonal).

This essay is about the planning of Stockholm's border regions (areas on the outskirts of the city) during the first seven years of the 21st century. It describes how planning decisions are made in reality, in respect to a 'green' perspective. By describing what a "markanvisning" is (the right to negotiate with the city about a certain piece of land) and by discussing examples of what has happened with a hundred applications for markanvisning, this essay shows how Stockholm's border regions are planned. In the majority of cases it is the initiative of the future developers that begin the planning and construction processes. Research shows that the application to get a markanvisning in Stockholm does not follow a clear, structured system. However, the existing system in Stockholm does work and it seems like almost all the employees within the municipality, the politicians, and the future proprietors are happy with the current situation. Interviews have been held with key individuals involved in the planning process.

This thesis was written during the autumn 2007. I wanted to understand the situation of the contemporary architecture in a perspective broader than merely the Swedish. I asked myself what remained of architecture if one would eliminate purely functional, aesthetical and ecological aspects. With help from literature I interviewed theorists in architecture, practitioners and a philosopher to hear their thoughts regarding what architecture can or should be about. The result of the interviews and the literature studies constitute the two initial parts of the thesis.

Wikileaks is using the new technical solutions to mount big leaks, consisting of secret or sensitive information from the government, institutions and business. This might profoundly change the media reality and it certainly means both new opportunities and new challenges for traditional media; the conditions for the journalists, the sources and the news reporting are changing. In this thesis the relationship between Swedish journalists and Wikileaks has been the focus; they both affect each other but the conditions for this relationship is not yet clear. Clearly there is an interdependence, but who really is dependent on the other and to which degree they are dependent on each other is still a question without a given answer.The aim of this thesis has been to discern a new journalism, and how this responds to the theories of Public Journalism and Journalistik 3.0. The main aim has been to examine what Swedish journalist thinks about Wikileaks, what their attitude towards Wikileaks are,  if and how they think that Wikileaks have affected the Swedish journalism.

Över hela världen pågår en kraftig urbanisering och idag lever mer än hälften av alla människor i städer. Många utvecklingsländer hinner inte med att generera hållbara och alternativa försörjningsmetoder till den allt större urbana befolkningen. Allt fler lever i en tillvaro som präglas av fattigdom. Kraftfulla planeringsstrategier krävs för att förbättra dessa människors levnadsförhållanden och därmed också verka för en hållbar utveckling. Uppsatsen presenterar det urbana jordbruket som en i dessa avseenden möjlig strategi. Urbant jordbruk finns i alla städer och har gjort det i alla tider.

Syftet med detta examensarbete var att undersöka några lärare, lärarstudenter och elevers erfarenheter av samt attityder till faktionstexternas roll i skolan. Detta undersöktes genom halvstrukturerade intervjuer med fyra verksamma grundskolelärare, två lärarstudenter, som har läst svenska minst två år, och genom en gruppintervju med fem gymnasieelever. En enkät användes i urvalssyfte samt som grund för den följande diskussionen. En inventering av skolbiblioteket samt svenskämnesinstitutionen på den skola där de medverkande lärarna arbetar har även genomförts. Resultatet visar att lärarna och lärarstudenterna anser att faktionstexter är intressanta både innehålls- och formmässigt, men att de används alltför sällan i klassrummet.

In December 2004 an earthquake coursed waves that hit Thailand. Over 5000 people died, and Sweden was the tourist country that has been effected the worst. The catastrophe precipitated Sweden in crises and the demand became high for Swedish government to act. Swedes followed the development via media, why media became the crucial element for how the public perceived politicians? acting.
