(O)möjligheternas plats? En diskursstudie av Garaget

A general topic underlying this master thesis is how the public library is being transformed through the subversion and re-articualtion of meaning according to different discourses. The aim of the study can be divided in to levels of analysis. At the first level, the aim is to investigate how categories such as users, needs and vision are articulated in a specific case ?the visionary project Garaget in Malmö, a project which in part include a public library inspired by Idea Store. The next level of analysis sets out to explore how the case of Garaget is related to a totalizing discursive struggle over meaning within the element the public library.

Småhusutformning och solenergiutnyttjande

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.

Olika typer av täckning och samodling och dess påverkan på antalet skadegörare i en Pak choi odling :

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

Konstgjorda våtmarksöar : flytande reningsverk?

År 2000 godkände Sverige EUs vattendirektiv. Det innebär att vi måste arbeta för att vattnet ska ha en god kvalité och det får inte ha för höga halter av förorenade ämnen. Vid förorening kan vattnet skada människor, djur och växter. Sverige måste ständigt jobba och förbättra reningen av vårt dagvatten. Reningen av dagvattnet och på vilket sätt det ska ske är något som ständigt kan förnyas och förbättras. Idag renas dagvatten med hjälp av dammar och våtmarker och reningen kan bli bättre med hjälp av flytande våtmarker. Syftet med denna uppsats har varit att ta fram mer information om flytande våtmarker och att sprida denna så att intresset och kunskapen ökar och förhoppningsvis även användningen av dem så att reningen av dagvattnet kan förbättras. Arbetet innehåller en litteraturstudie och resultat från intervjuer vilka bägge syftar att ta reda på hur en flytande våtmark fungerar, hur den är konstruerad, vilken typ av skötsel den kräver, vilka växter som fungerar bäst, hur de renar vattnet och hur man skulle kunna använda sig av dem här i Sverige. I arbetet finns det information om när en flytande våtmark renar som bäst, vilka typer av växter som bör användas och vilka typer av stommar det finns till den flytande våtmarken.

Vilka stora tänder du har! : En kvantitativ analys av fyra svenska tidningars rapportering om vargar under 2011 och 2012.

This BA Thesis in Journalism is a quantitative analysis of the coverage of wolves in Swedish printed media. Namely four daily newspapers, two national and two local. The two national newspapers are Aftonbladet which is a leading tabloid newspaper with national coverage and Svenska Dagbladet which is one of the two major newspapers with national coverage, as well as coverage of the greater Stockholm region. The two local newspapers are Falu Kuriren, which is located in Falun and mainly cover the province of Dalarna and Nya Wermlands-tidningen which is located in Karlstad and mainly cover the province of Värmland. These are provinces which have a large wolf population.As the work progressed we found that the newspapers have handled the coverage of the wolf in, what we believe, a good way.

Innehållet i Magasinet och Ess i svenska utifrån styrdokument och betygskriterier

This study focuses on two text books, Magasinet and Ess i svenska, both common teaching material in Swedish schools. Since Swedish school system recently got a new curriculum and grading criteria, the purpose with this essay was to see how well the teaching materials used in school match the new documents.Since the subject has not really been studied before, the chapter containing recent studies focuses on layout, appearance and contents of good teaching material. The survey that I have implemented includes studies of the two text books, with comparison of the new curriculum, grading criteria and previous studies of what makes a good text book.Conclusions were that Magasinet is very comprehensive and match the criteria and curriculum very well, even though it spans over four classes and has to cover a lot of information. However, since it covers so much information, each section sometimes feels not as thorough as it perhaps should have been. Ess i svenska on the other hand, is a good complement to use in ninth grade, if you have studied the previous books for seventh and eight grade in the series.

Religion i utvecklingssamarbete : En kvalitativ studie om hur anställda på Sida upplever religionsfrågor som komponent i arbetet

This study's main aim is to contribute with an insight regarding how employees of the Swedish International Development Cooperation Agency (Sida) experience religion as a component of development work in religious contexts. The study focuses on whether or not religion is given enough space within Sida's development work and if the policies of Sida are enough to cover the needs in religious contexts. To answer these questions we have interviewed six employees of Sida which holds experiences of development work in religious contexts. The results show a lack of knowledge and encouragement of these questions within Sida and that the interviewees experience religion as a complex concept. The study also shows that the interviewees find policies, methods and tools within Sida as inadequate to cover the needs of religion in development work.

Födosammansättning hos gråsäl (Halichoerus grypus) samt test av flotte för insamling av sälfekalier.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Investeringsbeslut för småskalig vindkraft : en fallstudie

Wind power is one of the sources of renewable energy which has to be developed further in order to lessen our dependence on non renewable sources of energy. It's mainly oil and coal which have to be replaced by green energy. Wind power is already established in many countries, for example Germany, The United States of America and Denmark but it has to be continually developed and expanded to meet the needs of the growing energy consumption in the world. During the last few years many types of small wind turbines have appeared on the market. These small wind turbines are an alternative to the big wind turbines or power generators which demand huge sums of investment money.A new target group can now buy the small wind turbines in order to cover their own usage of electricity.

Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Att formge en receptbok - är könsneutral design möjlig? / Designing a recipe book - is gender-neutral design possible?

The aim has been to investigate and describe how gender-neutral design, concerning typefaces and colours, can be created. Based on my results I?ve designed a cover for a recipe-book to make it appealing to both women and men. I have been doing my research based on questions such as; Does feminine and masculine design, concerning typefaces and colours exist? And if so what characterizes it? Does gender-neutral design, concerning typefaces and colours exist? And if so what characterizes it? Is it possible to design a cover for a recipe-book in a gender-neutral way, concerning typefaces and colours? The first part of my research consists of a literature study based on keywords such as gender, graphic design, gender theory, typeface, androgynous, visual communication, colour, shape, feminine, masculine, and book design.

Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :

Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden. The purpose of the study was to attain a greater knowledge about CCF practices.

Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?

Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.
