Mälarens vattennivå i ett framtida klimat

The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.

Hur olika skogsägarkategorier har försett sig med underlag för beslut och åtgärder efter stormen Gudrun : en jämförelse av medlemmar och icke-medlemmar, åbor och utbor samt kvinnor och män

During the 8th and 9th of January 2005 a devastating storm named Gudrun entered the south of Sweden and a big part of the forest owners got their forests damaged. The study objective was to investigate on which basis and how the affected forest owners made their managment decisions immediately after the storm and if there are any differences between different categories of forest owners. - Members ? non members in a forest owner association (FOA) - Resident owners ? non resident owners - Female and male forest owner The study is based on a questionnaire survey with the purpose to examine the most important counsellor and information channels of the forest owners. A total of 450 forest owners participated in the survey. Results show that all categories of forest owners prefer professional counselling rather than personal counselling.

Brottsrapporterande och engagerande : En kvalitativ studie kring polisens arbete  och kommunikation inom det sociala mediet Facebook

The purpose of this study was to understand whether there is a difference in how the Swedish police work with Facebook in two municipalities with different criminal records. The methods used were qualitative interviews with the ones responsible for the Facebook-sites and quantitative content analysis of different Facebook-posts, both from members of the Facebook-site and from the police themselves.Among the theories used in this study were the ?four-step relations process? by Cutlip, Allen and Broom, theory around public relations and theory around the public sphere by Habermas.The results showed that there is a difference in how the police uses Facebook between the municipalities and one of the conclusions is that this is mainly because of the ways that the police choose to work with Facebook rather than the difference in criminal records. Another conclusion is that the police get positive feedback from the members on their Facebook-site, and that how much the police uses Facebook as a tool depends a lot on how much resources they have to spend since the ones writing on Facebook are policemen and policewomen, and that the police do not have someone who works with the Facebook-site as a primary task.Keywords: Facebook, police, social media, qualitative interviews, quantitative content analysis, authority, public relations..

Tio ungdomars upplevelser av stress

Stress is something that has increased in recent decades among adolescents. Several reports indicate that young people today are more stressed because of the many demands they wear. They should be good in school, achievement expectations, get an education or job, make choices and think about their future. The purpose of our essay is that we want to explore and gain an understanding of how young people in the third grade in high school looks to stress. To conduct this study, we used a qualitative approach, by doing interviews with 10 high school students attending third grade at Västerviks gymnasium. The result we got out of the interviews was that young people experience stress differently, depending on their different as individuals. We found that there are different causes of stress, such as school, media, friends, demands from various quarters and choosing education.The interviews showed that some kind of stress was possible to handle for the adolescents, for instance by making schedule. Some stress from society was, on the other hand, more difficult to avoid..

Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

I nationens intresse - operation:jämställdhet- genuint engagemang eller projicerad legitimitet - En fallstudie på den Svenska Försvarsmakten

The Swedish Armed Forces is a public institution and consequently obliged to follow Swedish and international legislation. Thus, they are subjected to contrarious demands from different actors operating in its high-technological and high-institutional environment: to be a legitimate institution and at the same time operate with a high level of efficiency. This thesis is conducted with the aim of investigating whether The Swedish Armed Forces' steering document for gender equality is used to achieve visible and quantifiable results or if the document constitute a medium for reverberating legitimacy. To answer the research question, we applied a critical discourse analysis on the relevant documents and on the conducted semi-constructed interviews with members from different levels and positions in the organizational hierarchy. Subsequently, we came to the conclusion that the Swedish Armed Forces manage the demands for efficiency and legitimacy, which are forced upon them from the technological and institutional environment, by talking about them.

Pelletering av tallspån : grundläggande studier

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Förenliga motsatser? : En jämförande studie om aggregering och deliberation i två e-petitionssystem

This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

Gränsfall : en undersökning om skillnader mellan inomhus- och utomhusaktiviteter i förskolan

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Osynliga nyhetsoffer eller som du och jag : Framställningen av personer med funktionsnedsättning i Rapport och TV4 Nyheterna

In this study we examine to what extent people with disability participate in television news and how they are represented. We chose to examine one broadcast per day of SVT Public Service news program Rapport and commercial channel TV4 Nyheterna (TV4 News) during one month using quantitative content analysis and qualitative discourse analysis.We found that people with disability are underrepresented in television news. In Rapport only 1,9 percent of the total broadcasting time contained people with disability and in TV4 Nyheterna 3 percent of the total broadcasting time contained people with disability. In the news people with disability were often represented as stereotypes, most commonly as victims. The focus was often on the medical aspect of the disability and on the problems that people with disability had.

Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.

Att gilla eller inte gilla, det är frågan :  Hur användare förhåller sig till sidor på Facebook

The development of the Internet has led to a new platform for Web pages, Web 2.0. An interactive environment where users generate content. Facebook, which is one of the most popular social media sites, has opened up new opportunities for companies to communicate directly with individuals. Facebook has encouraged this by offering the technology and the possibility by developing the feature pages.The purpose of this study was to examine how Swedish Facebook users relate to company's presence on Facebook through pages. The study also intended to find out how Swedish Facebook users think that companies should behave on their Facebook page.

Enantioselektiv HPLC-analys med kirala stationärfaser bestående av makrocykliska glykopeptider och polysackarider

The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

Om jag säger Rinkeby, vad tänker du då?

The objective of this research was to study how two newspapers in Sweden, Aftonbladet and Expressen are creating an image of the Stockholm suburb Rinkeby. The method used to do the study was qualitative content analysis. Ten articles were chosen, five off either newspaper and were found on the internet homepages of the newspapers on 15 November of 2013 and 27 January of 2014. Several theories were used in the study. Agenda setting theory, a media theory that explains the power of media, Figuration theory developed by Norbert Elias that deals with power struggles between different groups in society.
