"Utanförskapets reservarmé": talet om Rosengård i svensk dags- och kvällstidningspress

The aim with this study has been to examine and to analyze the discourse of Rosengård in Swedish media. With the concept of discourse is meant here specific ways to speak about and to understand the world, or a part of it. In order to reach increased understanding regarding media presentations and constructions of Rosengård, I have done a study about how Rosengård has been presented in the Swedish daily and evening press during the violent acts that took place in Rosengård in the spring and summer of 2008, when youths regarding to media put cars and containers on fire, and also threw stones at fire engines and other emergency service vehicles when these had to turn out to put out the fires. The collected data, containing newspaper articles, has been analyzed on the basis of the critical discourse analysis, CDA, which is a mould of a textanalytical method. This study applies a social constructivist perspective.

Molecular analysis of insecticide resistance in pollen beetle (Meligethes aeneus)

The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

Effektivisering av energianvändningen i en förskola

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Energieffektivisering av skolbyggnad från 60-talet : Studie av Hållsta skola i Eskilstuna

In June 2006 the Swedish government decided that the use of energy in buildings should be reduced by 20 percent until 2020, compared to the level of energy used in 1995. To contribute to this goal, the real estate company ?Eskilstuna Kommunfastigheter AB?, set up own goals for their buildings. In 2009, the goal for schools was to have a maximum energy use of 118 kWh/m2year for heating and hot water.The school ?Hållsta skola?, just south of Eskilstuna, exceeds the limit since it used 270 kWh in 2008.

Studie i en studio - Undersökning av producenter och gitarristers syn på studioinspelning av elgitarr.

As I recently started to record in a studio, I almost immediately came to the conclusion that getting the right sound is not easy. I became curious about my recording procedure. What did I do wrong? How to place the microphone? Use of equipment? How is it possible to modify the sound afterwards? Are there any special methods that are commonly used among producers and/or guitarists? My thoughts ended up in a question ? What do producers and guitarists think of the guitar sound during a recording session in relation to the final production? In my research I interviewed two producers and two guitarists about guitar recordings. The results show that the quality of the guitar sound is in relation to production and style of music.

Reducering av produktionstryck i A-linan : Förflyttning av produkt

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Styr genus valet av Cover Story? : En fortsatt studie på projektet Cover Story, där genusaspekten kommer upp till ytan på ett intressant sätt.

Cover Story is a project, which students at Lillholms - and Ekholms School worked in during spring and fall of 2009. Several school subjects were integrated in project; social studies, art and Swedish, to empower the students to create, implement and design a magazine. The purpose of the project was to give the students the opportunity to fantasize about the future and their dreams by creating their very own Cover Story. During the project I realized that the student?s selection of magazine genre had a direct relation to the gender of the students themselves.

Att måla läppstift på grisen: En fallstudie om den interna interaktionen mellan Inköp och Miljö i arbetet mot hållbar utveckling

During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige

During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Enegiutredning Hotell Princess

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

Grafisk skärpa : ett arbete om gaturummet

The streetscape is a complex environment with a lot of different parts and users. If you look at the streetscapes main parts you have floor, walls, roof and furniture. The floor in the streetscape, the street, consists of the ground and the paving. It can be made of a lot of different materials with both architectonic and practical functions. The walls usually consist of the houses. They have a big influence on the streetscape depending on architecture, heights and widths.

Segelbåt, fjällstuga, husvagn och lyxbil... Är dessa att anse som onyttig egendom för fåmansbolaget?

Background: The Stop rule for buying in property was introduced through 1976 years legislation and its formemost purpose was to prevent companies to acquire property that was useless for the company. Assets such as cars, boats and arts were of current interest. At the same time as this stop rule was introduced, another stop rule was also introduced and this was meant to work to forbid the partner to buy property from the close company to a price that would lead to sell at loss for the company. After a government decision (1999:2000, Abolished Stop rules) the close company is no longer living under this restriction since these two stop rules have been abolished since January 2001. Purpose: The purpose of this thesis is to investigate which criteria are the basis to judge whether the assets is to consider as useful or not for the close company.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
