Dynamisk analys och utmattningskontroll med hjälp av fältmätningar och FEM : Fallstudie över SL:s Bro norr om Söderströmsbron

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Spolmaskangrepp är ett ökande problem hos värphöns

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

Screens : tävling om strandpromenaden i Helsingborg

The competition for the beach promenade in Helsingborg was announced in 2001 and was arranged by the city of Helsingborg. My contribution to the competition represents the main part of my thesis in the Landscape Architecture Programme. The competition entry is based on the concept of crossing screens of vertical elements which connect the pattern and structure of the city to the beach and the water. The different materials and designs of the screens relate to the various characters of the different parts of the area and they form a sequence and uniting theme along the beach. In addition to the competition entry which was made in 2001, the thesis contains a second part, made in the spring of 2006. It consists of an Introduction with the competition programme and a description of the starting points, a part called Method where the process is described, and the Conclusion with reflections on the competition entry and the process where I also introduce and comment on some other projects which in different ways have are connected to my concept. .

Frågan är - flera sanningar, en lögn? : en kartläggning av hur religion framställs i läromedel grundade på ett massmedialt flöde under 2000-talets första decennium

The purpose of this study is to examine how different religious traditions are portrayed in teaching materials based on news reports. The main question concerns the way in which religious practices and holidays are described and in which contexts religion is presented. The method includes a both quantitative and qualitative content analysis. The study concludes that certain religious practices are presented in a way that describes the practitioners as more faithful and homogenous than others. This was especially prominent among Muslims and to a certain extent Hindus.

Detaljerad FE-modellering

Detta examensarbete beskriver undersökningen av kärnmaterial i en sandwichpanel under belastning. Arbetet har utförts tillsammans med CCG i Laholm, Sverige. Kärnmaterialen lämpar sig vid design av sandwichpaneler på grund av sin låga vikt och sin förmåga att klara av högt tryck. Då materialet uppvisar ett ickelinjärt beteende skapar det problem vid design av sandwichpaneler och leder till att materialsammansättningarna tillverkas konservativa mot verkligheten. Projektet har gått ut på reducera designprocessen genom att bygga upp och simulera materialmodeller i programvaran ABAQUS för att kunna analysera och förutse materialets beteende.

När Hulken mötte Barbie : -Pedagogers förhållningssätt till könsstereotypa leksaker i förskolan

The aim of this study is to investigate how preschool teachers reason about gender stereotypical and gender neutral toys and other material. I would also like to see how the pedagogues reason about gender segregation when it comes to toys. To investigate the issue, I have interviewed three pedagogues from different preschools. The results showed that the work procedures differed a bit from school to school, although they all wanted to achieve the same goal. A goal that our curriculum mention as well: Not to make a difference between boys and girls.

Från alger till biodiesel - Den italienska drömmen?

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

A world of illustration - Ett utforskande projekt om Illustration som begrepp och koncept, dess gällande och möjliga användningsområden samt utformningen av en arbetsprocess

It is not about the perfect tune or pretty picture.It is always, always about the story. (Is or ought to be)When we release a new album, publish a book or show a brand newcollection of clothes or furniture etc. it is (or ought to be) because we havesomething to say (tell/share). The choice of language, in which we tell our stories,is vital for how they will be perceived.This is where illustration comes in. Illustration is a tool for storytelling, for contributingto the world in the most legible way.Illustration is legibility, it is the italic, the underline, the ?quotation mark?, the exclamation mark!It is not about the pretty picture.I want to talk about this.

Planerat kärnbränsleförvar i Forsmark : - med fokus på episyenit

It takes a very long time for ionizing radiation of used nuclear fuel toreturn to a natural background level, for this reason one of the requirements for theselection of the location of a repository was that the environment as well people'shealth would be protected from the harmful effect of radioactivity. This requirementmeans that the waste must be isolated in a geological formation. In Sweden therepository will be built in the crystalline bedrock. The location for the Swedish nuclearfuel repository at nearly 500 meters depth at Forsmark in Östhammar was decided 3June 2009. The repository will be located at Söderviken, close to the Forsmarknuclear power plant in a 1.90 billion year old bedrock that will accommodate 12,000tons of spent nuclear fuel.

Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.
