Textanalys av barnlitteratur ur ett etnicitetsperspektiv
In this exam paper, a text analysis has been conducted in the context of ethnicity, examining the most popular library books borrowed by children between the ages of 9-12 years old. The bookshave been selected at two different libraries, located in two different socioeconomic areas. The aim is to examine whether ethnicity plays a role in the choice and content of literature in the two areas. The analysis takes into account class, sex and gender, all of which combine in the context of ethnicity. The framework within which I have based my questions are; In the context of ethnicity, is there a difference in the content of the most borrowed children's books at the two libraries located in areas of diverse socioeconomic background, is the choice of literature affected by the area in which library visitors live and is the content of the most borrowed books specific to what children is each particular area can identify with ? Having analysed the most popular books at both libraries, it has been concluded that there are differences in the two areas when it comes to children's choice of literature.
Etablering av höstraps i mellansverige :
The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden.
There are many factors that influence the outcome of the establishment, e. g.
Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Den traumatiserade sexualiteten : En litterär motivstudie av sexualitet i Raymond Carver's "So much water so close to home"
Denna studie erbjuder en litterär analys av gestaltandet av sexualitet i den amerikanske författaren Rymond Carvers novell "So much water so close to home". Analysen lyfter bland annat fram den obligatoriska heterosexualiteten som den teoretiseras av Adrienne Rich och hur manlig kontroll av kvinnans sexualitet inom den heterosexuella institutionen tar sig uttryck i texten.Utöver det undersöks i analysen vilka principer som kan anses ligga bakom konstrueringen av sexualitet i novellen samt hur dessa tar sig uttryck. Den aspekten av analysen tar avstamp i Judith Butlers teori om diskursivt skapade kön och genus samt den heterosexuella matrisen som utgångspunkt för all sexuell åtrå. .
Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative
The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.
Konstruktion av testrigg för moderna ångexpandrar
This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.
Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden
Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern
hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of
mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two
prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in
close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
Läs- och skrivlärande : En studie av lärarhandledningar i svenska för årskurs 1
AbstractThe aim of this study is to find out how the central content of the compulsory school curriculum (Lgr11) is handled in three teacher?s manuals for instruction in reading and writing for grade 1, and how these consider interaction and variation in learning how to read and write. Through a qualitative analysis with a hermeneutic approach, the three teacher?s manuals in Swedish for grade 1 were subjected to a close reading. The result shows that parts of the central content of the curriculum are considered, but that it is by studying exercises and texts that these become visible.
Klicka här för gemenskap : Hur interaktivitet skapar engagemang och lojalitet
Digital marketing has been changing continuously and rapidly since the introduction of Web2.0 ten years ago (Lin, Li, Deng, & Lee, 2013). Companies are now engaging their users intheir digital marketing by providing with interactive contents in digital campaigns. The digitalcampaigns are getting more converge with SNS (social networking sites) in order to let the usershare the content with others and therefore the e-WOM (electronic word of mouth) helps thecompanies digital campaigns to be shared by more users (Moran, Muzellec, & Nolan, 2014).The interactive content in the digital campaigns have shown to provide for engaged users andtherefore leads to loyal users. The reason for this has its roots in the culture of consumptionthat has brought our everyday consumption to a whole new level where we no longer justconsumes a product, we are the brand (Davis, 2013).The study, Click here for solidarity, aims to explain the interactive phases and rhetorical elementsthat companies use to engage the user to interact with the content of the digital campaigns.The study is based on four digital campaigns in four different market areas in order to providewith an overall picture of how companies work with interactive and rhetorical elements. Thusthe study falls into the area of marketing and branding.
Livet efter sfi : Vilka tankar har några sfi-elever om sin delaktighet i det nya landet och hur har de lyckats med att förverkliga uppsatta mål?
Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements, used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor
Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.
Falu gruva och hållbar utveckling
AbstractFalu Copper Mine and Sustainable DevelopmentKarl-Markus AnsnaesFalu copper mine was Sweden?s oldest mine industry which lasted for almost a thousand years. Throughout the history its area has been vastly contaminated by sulfur oxide. The contaminations has created the mining area to an environmental risk zone which has the ability to spread out into the Falu River. The river has its connections to the Dal River which is discharging towards its mouth in the Baltic Sea.
En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö
The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.
Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007
On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).
Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme
The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.
