The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.

This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

Politics in today's society unfolding more and more in the media, but the media content is limited. Therefore, the media must constantly make choices, choices which are specific to each object. The purpose of this study is to examine how Olof Palme is portrayed as a politician and private individual in the documentary film Palme - älskad och hatad, and also how Carl Bildt is portrayed as a politician and private individual in the documentary film Bildt - excellensen.To study the documentary films I use a qualitative textual analysis with a focus on a narrative analysis. In the narrative analysis, I have been inspired by the categoricalcontent- based approach to study the documentary films. In my analysis, with the help of theories of mediatization of politics, documentaries and stories, I interpret and analyze the films to make them more understandable.The conclusions of the study is that Palme in his role as a politician is portrayed as a humane person who cares about the individual.

Women are subordinate of men in the society, this is visible both in work places and private lives. Equality between the sexes is daily discussed in politics and the private sphere. As this is a hot topic which is debated within many areas, one of those is film production, we chose to write this essay about how the view of women has changed in movies over time. If equality doesn?t exist within the film media, then it will be hard to change the society?s point of view.

Private Banking är en banktjänst för förmögna individer och företag som syftar till att hjälpa dem med förvaltning av deras kapital men även andra tjänster såsom hjälp med deklarationer. Storbanker idag kämpar med att återfå kunders förtroende efter finanskrisen 2008 och fokusen på riskhantering har blivit viktigare. Kunder har blivit mer känsliga för risker och därmed försöker banker dra fördel av detta genom att skapa värde i riskhanteringsprocessen. I detta värdeskapande eftersträvar man en bra relation till kunden som därmed kan generera i ökade marknadsandelar. Vår problemformulering i uppsatsen blir då följande: ?På vilket sätt kan den svenska storbanken Nordea öka sina marknadsandelar inom Private Banking med hjälp av riskhantering??Syftet med vår uppsats blir därmed att få en djupare inblick i hur Nordeas Private Bankingtjänst arbetar med riskhantering och hur det påverkar deras marknadsandelar.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

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.

Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical. The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank. The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data. The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.

The aim of this study is to investigate how länsstyrelsen as a supervisory authority to private compulsory care-institutions works, to guarantee adequate institutional care of unprivileged children and youth with special problems.In order to reach this aim the following questions are to be answered:? Describe länsstyrelsen´s supervision of private compulsory care-institutions (HVB-hem)? How does the officials at the three chosen county administrative boards find about the responsibilityTo answer the questions of this bachelor thesis I have chosen to apply qualitative methods, by interviewing five supervisory authorities from länsstyrelsen, in three different county administrative boards in Sweden.The findings of the study show that officials sometimes find it hard to know the exact meaning and differences between accountability and to be accountable. It also shows that they tend to think that the relationship between länsstyrelsen and the private compulsory care institutions is complicated. Because the officials have two part relationships, they have on the one hand a consultative role and on the other hand the supervising role.Keywords: Länsstyrelsen, Hem för vård eller boende (HVB-hem), Ansvar, Ansvarsutkrävande, Socialtjänstlagen.

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.

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.
