Det postkoloniala resandet i Egypten : En diskursanalys av resebroschyrer

During the colonial period Europeans travelled to Egypt. The French had explored Egypt through the mapping and this was published in a collection of books called Déscription de l?Égypte. Exhibitions and publications like Déscription de l?Égypte, which aimed at giving a view of Egypt, raised public interest for journeys to the Orient.

MEMS baserad referensoscillator

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

Contrarian Strategier - ?En eventstudie på den svenska aktiemarknaden?

Syfte: Att undersöka om det finns belägg för att contrarian strategier genererar högre avkastning än Stockholmsbörsens marknadsindex och om detta i så fall beror på en småbolagseffekt. Metod: I vår event studie valde vi att undersöka stockholmsbörsen under åren 1993 till 2005. Under perioden skapade vi 8 portföljer med 20 aktier i varje, för dessa bolag satte vi ett gränsvärde på 150 Mkr. Vi utförde även ett liknande försök men då med en gräns på 1 miljard och satte antal aktier i portföljen till 10. Detta för att testa förekomsten av en småbolagseffekt på våra resultat.

Miljöarbete inom den civila luftfarten

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Användning av hörselskydd i bullrig arbetsmiljö

Buller är ett stort arbetsmiljöproblem, som kan leda till ohälsa. Det är viktigt att personal som i sitt arbete löper risk för hörselskador använder hörselskydd. Studiens syfte var att beskriva och jämföra användning av hörselskydd bland personal som arbetar i bullrig arbetsmiljö inom verkstadsindustrin. Studien var en tvärsnittsstudie med en deskriptiv och komparativ design. Data samlades in med hjälp av en enkät.

Kultur och ekologi i Amazonas: GIS-bearbetning av historiska data om indianfolkens utbredning

This study deals with some contested issues regarding prehistoric cultural development in Amazonia and the colonial impact on the native inhabitants of the area. It focuses on the relation between groups belonging the language families of Tupí and Gê, on one hand, and the different ecological zones that they inhabit, on the other. GIS mapping is used to visualise the distribution and movements of these groups in relation to ecology and the impact of European colonization. GIS is shown to be a useful methodology for analysing historical data derived from written sources and maps. The results of these analyses are discussed in the light of different theoretical perspectives.

Säkrare arbetsmiljö med traktorer i vårbruket :

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

Metodutveckling för analys av serglycinuttrycket i blodet hos hundar :

The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.

Egenvård och behandling vid recidiverande aftös stomatit

Physiotherapists treat people with different views of the world and medical beliefs, which require a good understanding of cultural differences. One way to achieve cultural understanding is through self-reflection in a new context. During five weeks the authors, two physiotherapy students, completed a clinical practice at the rehabilitation center Pina Palmera, Zipolite, Oaxaca, Mexico. At the beginning of the period a critical incident was chosen, when the head physiotherapist for the ward Cuidados Especiales intended to sell jewellery to the authors during a treatment of a patient. The authors have by using the reflection framework "Framework to guide reflective process", and Interpretive Phenomenological Analysis (IPA) for analysis, discussed different ways of communication, adherence, education, and self-reflection and critical thinking.

Modell för dimensionering av AGV-system inom tung industri

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Buller i bostäder : Projektering av bostäder med hänsyn till trafikbuller

Många av Sveriges kommuner vill förtäta sina städer med bostäder och lokaler för att bygga ett mer hållbart samhälle. Ambitionenär att kunna fylla de luckor som finns i stadsbilden och använda stadsmark som tidigare inte är bebyggd för bostadsbyggnation. Examensarbetet behandlar de problem som trafikbullret genererar och som måste hanteras vid projektering av nybyggnation, samt undersöker de krav och regler som styr den tekniska utformningen och planlösningen av bostäder med hänsyn till trafikbuller. När Skanska tidigare har projekterat bostäder i stadskärnan har man upplevt problem med att få bygglov när den föreslagna planlösningen har sovrum mot bullrig sida. Fokus ligger på de krav och råd som styr placering av sovrum och försöker hitta lösningar som gör det möjligt att få bygglov med placering av sovrum mot bullrig sida.

Energianvändning på Volvo Lastvagnar Tuve

Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).

Ni får ju prata, men... : om skolans pedagogiska idéer och uppdrag utifrån begreppet kommunikation

The purpose of this study is to describe the three most significant pedagogical ideas and their impact on the national curriculum from the concept of communication. As the school is a social learning community this study looks at some teachers? perceptions and experiences of teaching with a communicative approach, and the obstacles they claim to meet. The educationist Kieran Egan argue that these three pedagogical ideas are incompatible and that a curriculum that compromises them is doomed to fail. He mean that a new coherent view on education is required and should be based on students? understandings.
