Ett nytt pedagogiskt material! : 4DFrame, hur kan man arbeta praktiskt med det?

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Lågtempererad fjärrvärme i Umeå

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

Hästars aktivitet och liggtid på madrasserade gummimattor i box

Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with support against the ground for the head. The lying behavior can be affected by external stimuli such as age, food intake, bedding materials and if the horses feel safe or not. This study investigates the lying behavior of horses on different bedding materials; wood shavings and filled rubber mats (HIT SoftBed®).

Små barns lärande i skogsmiljö : En kvalitativ studie om hur pedagogerna inom I ur och skur arbetar med de yngsta barnens lärande i skogen

The purpose of the survey was to find out how early childhood teachers work with the curriculum of I Ur och Skur with children between 1-3 years in the forest and how such educators are using the outdoor pedagogy in the forest environment in preschool.In order to answer the study's aim and objectives interviews were performed with six teachers in I Ur och Skur kindergartens.What emerged from this study is that forest excursions are a central part of the curriculum and is seen as their educational place. The teachers are working to create a feeling of security among the youngest children of enjoying the woods and also to raise an interest in the children. Natural materials are used during the forest stay and no other toys or materials.The results reveal that educators work to get the smallest children to use and develop their imagination at play and at the same time they are involved with the children in their discovery of the woods. With the smallest children in kindergarten it involves being on the level of children and as a teacher to have the flexibility to change the forest stay environment if needed..

Förädling av textil- En studie om att skapa mervärde av skänkta kläder och textilier

Våren 2011 beslutade Röda Korset i Sverige att sluta skicka skänkta kläder som bistånd till katastrofområden. Röda Korset ställdes nu inför frågan vad de ska göra med de skänkta klä-derna för att omvandla dem till en resurs.Uppdraget var att i samarbete med Zäntrumprojektet och Röda Korsets secondhandbutik Ku-pan förädla de skänkta kläderna på ett miljövänligt sätt. Tanken är att Zäntrumprojektet ska sy om de skänkta kläderna till nya produkter som sedan ska säljas i secondhandbutiken Kupan.Syftet med den här uppsatsen är att finna ett sätt att förädla de skänkta kläderna och skapa nya produkter av dem. Vidare ska de skänkta kläderna skapa bättre resurser till Röda Korset som de kan tillgodogöra sig i sitt välgörenhetsarbete. Produkterna ska vara skapade på ett sådant sätt att de avger minsta möjliga avfallsmängd, främjar hållbar utveckling samt är attraktiva för Röda Korsets secondhandbutiks kunder.

Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Biblioteket bokskogen : Perspektiv på bibliotek för barn på sjukhus

The purpose of this study is to focus on library service for children in a hospital, which in turn is seen in relation to a traditional children s library. Four aspects of library work were investigated. These aspects were working methods, partners of co-operation for the libraries, media policy (acquisition, use of the collection and circulation procedures), as well as programme activities for children.The research method was qualitative and comparative in nature, consisting of case studies of two libraries : (1) the library in a children s hospital, known as Bokskogen at Astrid Lindgren s children s hospital in Stockholm and (2) a traditional children s library, the children s department at Eslövs city library. In each library interviews were conducted. The investigation shows that the librarians in the hospital library must be more outreaching and active in order to stimulate children to use library materials.

Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?

Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

Vakuumisolering ? Ekonomiskt försvarbart för småhus?

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

På vilka sätt kan bibliotek vara användarvänliga för människor med dyslexi?

The purpose of this study is to find out how libraries can be user-friendly to people with dyslexia by focusing on how adult dyslectics experience the library. Data were collected through literature and interviews with adult dyslectic students. Two different types of user studies served as a theoretical framework; one was an individual-related study by professor Wilson and the other was a system-related one from professor Buckland. The findings in this study shows that dyslectic library users often experience difficulties when seeking for materials in the library, due to the libraries organisation of material according to the written language. Through technical aid and a more user-friendly organisation of materials it may be easier to find relevant material for dyslectics.
