Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

Purpose: The purpose of this thesis is to examine whether some periods of declines in Swedish real credit can be explained by a credit crunch. Is it further possible, with these results, to do any conclusions about the banks behaviour in the on going financial crisis that has shadowed the country since 2007/2008? Method: A credit crunch is here defined as a period of supply-side restrictions on loans which doesn?t reflect the ongoing interest rates. By estimating a supply and demand function with a disequilibrium model the excess demand- and supply for credit due to different periods can be calculated. Conclusion: A credit crunch has been present during a period after the banking crisis of early 1990?s.

Det här examensarbetet bygger på översättningsarbetet med Elisabeth Bernsteins "The meaning of the purchase. Desire, demand and the commerce of sex". I den förberedande textanalysen undersöker jag några viktiga aspekter av artikeln. I min fördjupningsanalys tar jag avstamp i termen "re-gendering" och gör en djupdykning ner i engelskans "sex" och "gender" och svenskans motsvarigheter "kön" och "genus". Mitt syfte är att försöka reda ut vad som ligger bakom dessa begrepp och termer, för att sedan kunna producera en välmotiverad översättning av just "re-gendering".I PDF-filen ingår både analys och översättning..

As we travel more and more by train it becomes increasingly important that the time we spend traveling, is of great quality. This has been the foundation of this master thesis and has shaped the outcome of it. The traveling experience, that is, the experience of the landscape that flashes by outside the train window, is an important aspect in railway planning and an aspect that should be taken into greater consideration. The purpose of this master thesis has been to examine how to compose or improve the travel experience for an already planned high speed railway and how the travel experience can be combined with other aspects, which have claims on the landscape. This thesis is based on a literature study and a case study of Ostlänken. The work describes Ostlänken, a planned high speed railway in Sweden between Järna and Linköping, with top speeds at 300-320 kilometers per hour.

For better understanding of how users interact with the video on demand service Netflix a study was conducted in 10 Swedish households. This study is based on the well-established heuristic evaluation method of Jacob Nielsen, which we modified slightly by letting the users to act as ?evaluation experts? and informing them about the heuristic rules of thumb during the evaluation process. The purpose of this study was to identify usability problems when people interact with Netflix? interface.

This thesis examines the establishment of auditors as third party assurers of sustainability reports in Sweden. This is done through a qualitative case study that examines the subject from both a preparer?s and an assurer?s perspective. Empirical data was analyzed using a combination of agency- and legitimacy theory. The study reaches the conclusion that sustainability reporting companies in the study demand a verification service for reported sustainability data in order to increase creditability, meet increased stakeholder demand and increased accounting complexity.

Author: Johanna Jarl and Marie WestphalTitle: Co-operation and Collaboration The Social services and Child- and adolescence psychiatry joined action [Translated title]Supervisor: Mikael SandgrenExaminer: Torbjörn HjortChildren and adolescences that have both psychological and social problems is an increasing number of the society. It used to be a demand that Social workers and personnel at Child and adolescence psychiatry had interdisciplinary collaboration, today it is more then a demand it is a requirement. The aim of this study was to understand how the personnel at the Social services and Child and adolescence psychiatry look at the cooperation between the two organizations in Sweden.To be able to accomplish this study we have interviewed four persons employed at the Social services and three persons employed at Child- and adolescencepsychiatry all of them were interviewed individually. To be able to analyze our material from the interviews we have used new institutional organization theory and Goffmans dramaturgic perspective at teams. The interviews showed that there is collaboration between the organizations on all levels, but that the organizations have different priorities.

The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.

How accessible is the city? Is there more factors than merely the strictly physical that affect how accessible the city is perceived? These questions are the starting point of this study. The greatest emphasis, in this study, is placed on the perceived parameters that affect us humans when we move in our cities. Experiences and internal images can change our behaviour and prevent free movement in the city. The result from this study shows that a city can not be seen as fully accessible unless both the physical and the perceived accessibility are fulfilled.

During the last ten- fifteen years the Eurasian lynx (Lynx lynx) population in southern Sweden has increased considerably. This area has a high density of both people and roads and have a higher roe deer (main prey of lynx) density than the rest of the country. Movement patterns such as how long animals utilize their kills and how far they travel from their kills between revisits is unknown for lynx in southern Sweden. The aim of this study was to examine how different factors affected the time lynx used their kills and the distances they travelled from the kill between revisits. The data was prepared and calculated using ArcGIS and the study is based on 98 ungulate kills and 12 lynx individuals.

We have from three studies examined how adolescents and young adults, actors and the researchfield describes the preventive and health promotion work with sexual health. The questions weasked ourselves was based on what efforts adolescents and young adults demand, whether there aredifferences between age, gender, place of residence, ethnicity, employment, and sexual orientation.Furthermore, we investigate if these requirements are consistent with the offered interventions fromparticipants, as well as which perspectives the work with STI / HIV and SRHR issues should bebased on. The investigation concerns the work of Västra Götaland and is answered by interviewswith participants regarding the activities offered by actors, a quantitative analysis and text analysisof the answers of adolescents and young adults, and an international research overview of theresearch field. Our results show a high demand for basic preventive work from the adolescents andyoung adults. Furthermore, there is an increased demand of action from men, LGBTQ group anddepending on the place of residence.

The company is currently in a stage of improvement and has therefore taken the help of students at School of Engineering, Jonkoping University. The current production is batch, production layout is fixed. A bottleneck is created after the first station which leads to large efficiency loss.  The meaning of this report was to provide a layout suggestion with balanced workstations to a new production line. The conditions were that the production line would be one-way, driven by customers order and meet a demand of 40 products per week.

The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.

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.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.
