Skolan i universum - att förklara det ofattbara : Astronomiundervisningen i skolan på 1900-talet
This is a study in how astronomy has been taught and is being taught in Swedish schools from 1905 to this date with an emphasis on the latest 30 years. It concerns the regulations and methodical recommendations/curricula for Swedish junior high school/Swedish Comprehensive school for the years 1905, 1933, 1955, 1958, 1962, 1969, 1980 and 1994. The matter of integrating astronomy with other subjects and different methodical approaches is also considered. The problem with textbooks written only for one subject when the teacher tries to integrate subjects is emphasised.Physics textbook analysis shows that astronomy teaching has over the years developed, from being based on observations, to become more and more theoretical. It also shows that the amount of practical exercises has been fairly constant in physics textbooks during the seventies end eighties but now in the nineties varies a lot from textbook to textbook. The amount of liberty the textbook gives the pupil in finding knowledge and answers himself in the practical parts of astronomy was at its lowest during the seventies.
Relevans och svårigheter i användandet av vardagsteknik i dagliga aktiviteter hos yngre vuxna
Vi lever i ett informations- och teknologisamhälle och i våra dagliga aktiviteter omges vi av vardagsteknik (VT) på olika sätt och i olika svårighetsgrad. Denna VT kan innefatta allt från brödrost till mer avancerade datasystem och tjänster. Tidigare studier visar att personer med kognitiv funktionsnedsättning kan uppleva svårigheter i användandet av VT i sina dagliga aktiviteter. Dock finns inga studier som visar relevans och svårigheter med VT för yngre vuxna utan kognitiv funktionsnedsättning. Därför vill vi med den här studien beskriva relevans och svårigheter i användandet av VT hos yngre vuxna utan kända kognitiva funktionsnedsättningar.
En IT-forensikers kamp mot IT-brottsligheten : En studie om arbetssätt hos polisens IT-forensiker
The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

Lärare, digitalteknik och motivation : En studie om vilka aspekter som påverkar lärares motivation att använda digitalteknik i undervisningen
Studiens syfte är att utveckla kunskap om lärares motivation till användning av digitalteknik i undervisningen. Ämnet belyses genom frågeställningarna; Vilken förståelse har lärare för den digitala teknikens roll i undervisningen? och Vilka aspekter påverkar lärarnas motivation till användning av digitalteknik i undervisningen? I studien deltar fem verksamma lärare som undervisar i årskurs 1-6. Utifrån semistrukturerade kvalitativa intervjuer beskrivs och kategoriseras aspekter som påverkar lärarnas motivation till att använda digitalteknik i undervisningen. Studien visar att tvetydighet präglar lärarnas förståelse för den digitala tekniken. Lärarna uppvisar en förståelse för teknikens möjligheter och utnyttjar den för personlig utveckling och som informationsbank.Det framkommer dock inte lika frekvent att den digitala tekniken används i undervisningssituationen. Det är flera aspekter som påverkar lärarnas drivkraft att använda digitalteknik i undervisningen.
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.
Könsselektering av spermier från lantbrukets husdjur
Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.
Datahantering vid dynamiska webbteknologier : PHP eller ASP?
The last couple of years the use of Internet has changed in the way that the web pages can be affected of the person that uses them. Because of this dynamic Internet technology has emerged that makes it possible for a web page to receive information from a web browser. This information can then be used to affect the appearance of the page. PHP and ASP are two dynamic Internet technologies. They are integrated in HTML and are executed on the web server.

Dark Side of Wonderland - en kort 2D-animation med syfte att väcka intresse för en online serietidning
My objective for this project was to create a short but thrilling 2D-animation
intended as promotion for an online comic book. The purpose of the project was
to learn more about animation and graphics, to further my artistic skills and
to learn how to work in Adobe After Effects. I also wanted to learn more about
scheduling, project methods and how to handle stress. During the ten weeks of
the project I have created the story, the storyboard, the character design, the
backgrounds and the animation. The voice over was recorded with the help of a
fellow student who also made the music and the sound effects.
Lärande med Teknik : Användning (och Icke-användning) av IT i Skolan
For a long period of time there have been discussions about the need to modernize, to keep up with the changes in our society. The schools as a result have to keep up and adapt in order for the education to be up-to-date. This includes the technological developments. Many steps have been taken and mighty sums have been invested in order to keep up the pace ? but are there any consequences from these kinds of investments? In this report I?m going to take a closer look on a recent addition to this phenomenon that were installed by means of a top-down approach and study the teachers and how they have adapted and view the change in their environment ? namely the newly installed interactive writing-boards.The questions I will study include how the teachers express their view about the installation of the interactive writing-boards.
Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation
The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas
digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards
to relevant system parameters. The purpose was to evaluate if the technology is a possible solution
to reduce deforestation and support Malawi in climate change mitigation and adaptation.
The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine
which one was best suited to utilise as a digester substrate. After the installation, measurements of
temperature, pH, biogas production, biogas composition and system functionality were made.
The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

H2 För racing
AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.
Brand: "Øresund" - analys av regionen som territorialiserad simulering
The topic of this thesis interest is the relation between branding as a place making/marketing technology and the process of regionalization. The main proposition advocated is that the officially communicated image of the Øresund Region, as a cohesive place and community, is a space that has been configured with branding and can be described as a territorial simulation. The concept of territorial simulation consists of two conjoined terms: simulation which aim at explaining the idiosyncratic brand image, as a social formation, which does not represent the place it imitates but commoditise it; and territorial which seeks to visualize the process of the unfolding of this image as a territory. The main argument is made in the third chapter, which traces the process of actualization of the brand image as a territory: ?Øresund?.
