The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

This joint study has researched the use of non-European history in a Swedish textbook for the High School course History 1a1 as well as internet based material regarding the same issue. The aim of this study was to clarify the use of non-European history in regards to the Eurocentric theory.As for the textbook analysis the purpose was to research what non-European history was mentioned in the material with regards to geographical location and the events that were mentioned, as well as to study how much non-European history was included in the material compared to European or Western history.The study of internet based material aimed to show what kind of teaching material could be found on internet based databases by and for teachers. The study aimed to show how well the material handled non-European history, as well as to what degree the material used European perspectives when dealing with non-European events and geographical areas.In our thesis we have created our own definition of the theory regarding eurocentrism. The method used was a combination of a quantitative and a qualitative discourse analysis of the texts.Our results showed that the textbook was overwhelmingly Eurocentric, not only giving vastly more focus to the European parts of world history, but also using European perspectives and ideals to describe non-European events and areas. The internet based material, on the other hand, proved more diverse and less biased, but also more difficult to find and less plentiful.Our conclusion, then, is that teachers have to choose between the risk of letting their students develop a severely limited and heavily Eurocentric view of the world, and the additional workload required to find and organize non-textbook material to broaden their students horizons.We hope our study will contribute to the discussion of the place of Eurocentrism in today?s global and multicultural society..

Shopping for groceries often means that, as consumers, we travel to the grocery store ourselves, by ear, bike or on foot. At the store we pick out the groceries that we want, go the register and pay for them. During the last couple of years consumers in Sweden have been given the opportunity to let someone else select and transport the groceries to their home instead, so called home shopping. As this report is being written, the possibility to buy groceries this way is somewhat limited, but many forecasters believe that in the near future it will increase immensely. Because of the large volumes of groceries that are being transported, there is great transport work being done in the supply chain.

I denna studie undersöker vi inomhusmiljö och material i två Montessoriförskolor. Våra frågeställningar handlar om hur inomhusmiljön är utformad och hur materialet är placerat i två Montessoriförskolor, samt hur två pedagoger i två Montessoriförskolor ser på miljö och material utifrån följande nyckelbegrepp från läroplanen för förskolan: utmaning och stimulans, initiativ och självständighet samt demokrati och medinflytande. I vår studie utgår vi främst från Maria Montessoris teorier angående miljö, material och självständighet, men tar också upp andra teorier kring miljö. Vi använder oss av observationer och kvalitativa intervjuer, som grundar sig på en pilotstudie som vi genomförde i en traditionell förskola. Resultatet visar på att miljön och materialet i de två Montessoriförskolorna tillåter barnen att ta egna initiativ och vara självständiga.

The intent with this paper is to investigate the medieval habitation in central Old Uppsala. This time-period has over the years been neglected. Therefore I wish to summarize and ana-lyze the medieval habitation to see what can be said about its continuity, and also to investi-gate why it is located in certain areas.Due to the amount of source material I have limited my investigation area to the central Old Uppsala. It is possible that this limitation will affect the result of the research but without the limitations the investigation area would have been too large to handle.The source material has been collected from excavation reports and the summarized. My theory is material culture and material agency.

The healing process of human bone can be aided by the presence of differentmaterials. A material that is transformed into bone when in contact with bone iscalled a boneconductive material. By transforming into bone the material reduces thetime that it takes to heal a fracture. This report is a study of existing boneconductivematerials on the market to see if there is a material available that would be suitable totest on larger fractures. The wanted application is to be able to heal fractures up to50 mm which is a fracture too big for the body to heal on its own.The healing process of human bone can be aided by the presence of differentmaterials.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

This essay studies the funnel-beaker ceramic in connection with the megalith graves in South Scandinavia. In my work I have described the nature of ceramics and looked on the crockery types and ornamentation and then discussed the use of the material in a ritual perspective. In the first part I have focused on the critical aspects you have to think about when you do a study like this one. In the second part of this essay I have done a case study, with the ceramic material, in three passages graves in the area of Falbygden, Western Sweden and studied the ceramic material and the nature of it in South Scandinavia as well. Then in the third I discussed the potential use, there is two, of the ceramic material in general of South Scandinavia and looked at it in a ritual perspective..

This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.

The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

The purpose of this work is to investigate how 4-5 year olds perceptions of materials and material properties can be developed through an educational activity. The study is based on two interviews with eight children in that age category. The interviews were conducted before and after an activity where the children were first introduced to the subject by the tale of The three little pigs (Harris, 2009) and then given the opportunity to explore various materials related to the book. The kids got to experiment and explore how water affected materials and to compare different materials properties. The children were also attracted to build and create the material that was offered during the activity.

Detta examensarbete visar resultatet av en undersökning om hur språklärare i engelska, franska och tyska på gymnasieskolan använder sig av autentiskt material i undervisningen och hur de tror att detta påverkar eleverna.En kvalitativ forskningsmetod har använts och därefter har resultaten analyserats med ad hoc-metoden.Resultaten visade att nästan samtliga lärare blandade läroböcker och autentiskt material i sin undervisning för att ge variation. Den främsta anledningen till detta var att lärarna upplever att elevernas motivation ökar dåundervisningen varieras och om eleverna kan se en viss verklighetsanknytning. Vissa skillnader mellan språken påvisades, då engelsklärarna i större grad uppgav att de använde autentiskt material i undervisningen. Lärare ityska och franska menade oftare att brist på material och elevernas kunskapsnivå förhindrade arbetet med autentiskt material. Lärarna påpekade även att kursplanen inte hade någon påverkan gällande materialet, utan attdet var varje lärares beslut att ta..
