En fenomenologisk studie om hur ungdomar upplever sin tillvaro, relationer och framtidsvisioner.

This project aims to obtain a deeper understanding of what it is like to be young today, and of how young people experience their lives. Identifying and uncovering the process of meaning constitution concerning young people's thoughts and feelings within each subjective individual, and their visions about the future as well as how they experience relations to other people in their surrounding, was achieved with a phenomenological approach. The participants were asked to write a self-report in answer to a carefully formulated question.The received reports were analysed according to the method of Meaning Constitution Analysis and Sphinx Lexica. The result showed that young people's lives are both complex and unique. They rather write about friends than family and write less about the future than we first assumed.

Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro

Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.

Viskningar från en grav. Att se ett förhistoriskt samhälle via gravmaterialet

Since the down of archaeology much of the resurges has focused on graves andgrave materials. This essay is an attempt to interpret a grave material to the society of the living, to investigate what a megalithic grave material can tell us about the society that made them and the people that were buried in them. The study is focused upon two megalithic graves in Löderup; Ramshög and Carlshög. A study of the bone materiel, building construction and building material at Ramshög and Carlshög is done and then compared with different theories that are made of Ramshög and Carlshög and of other megalithic graves. By studying different theories of megalithic graves and comparing these with Ramshög and Carlshög I have tried to evaluate which ones that are relevant in this case.The megalithic graves primarily shows some kind of change, in society or in their way of looking at the dead or the life after this.

Torkat bioavfall som jordförbättringsmedel

The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

En studie av normerna kring fildelning och piratkopiering

In this paper I have focused on the underlying reasons for people and piracy. The paper starts with a presentation of the Swedish laws of copyright as they are constituted today and the new law that is supposedly being ordained the 1st of July, 2005, a brief summary of what its effects will be for the people, according to the authorities and the critisism that has developed around it from the net-pirats. Then follows a definition of the expression "norms" and what it means here in my paper.Now comes a presentation of the research I have been doing, in the form of a survey concerning why and how often people download copyrighted material from the net, and if they have ever sold any pirated copies to more than selfprice and, if so, to whom. The presentations shows that the majority of the people that are downloading copyrighted material from the Internet is doing it for the own personal use and not to make any money out of selling the material on, since most people consider it unfair to charge for something that they have got for free.The survey also shows that many of those who download copyrighted material also upload it because it gives them a satisfactory feeling of giving something in order to get something. The survey also shows that although most of the people taking the survey knows what the new law means it has not affected them in anyway.

Exkursion genom Sibirien : att representera den mänskliga upplevelsen av världens största landskap

Det här arbetet undersöker landskapsrepresentation med fokus på stora landskap. Under en resa längsmed transsibiriska järnvägen har vi, med hjälp av olika dokumentationstekniker, samlat in material i syfte att utforska för oss oprövade sätt att representera stora landskap. En metod för representation som skapar överblick och samtidigt fångar den mänskliga upplevelsen av landskapet eftersöks. Insamlingen som handling har varit central för projektet och det material som ligger till grund för arbetet är i huvudsak vårt egeninsamlade material från resan. Två olika förhållningssätt till insamlingen av material har tillämpats, ett intuitivt och ett utifrån förutbestämda regler. Inledningsvis för vi en teoretisk diskussion som problematiserar representation av stora landskap.

Gravritualer vid gånggrifterna på Falbygden : En undersökning av den materiella kulturen inne i och utanför graven

This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.

"Land skall med lag byggas" - en studie av policyprocessen kring ett lagförslag -

This thesis concerns the policy process of a proposed bill. The specific bill constitute a new penal law which is supposed to replace the old penal law from 1974.The questions asked considers what in the foregoing policy process that has proceeded, affected and also characterizes the proposed bill. In order to be able to produce a deep and reliable analysis to this question I use two different theories.The first theory being used consists of John W. Kingdons theory of ?multiple streams? which I use to answer the specific question ?what can be recognized to have proceeded and characterize the policy process that the penal law bill involve??.The second theory consists of Peter Santesson-Wilsons development of symbolic policy theories which is given a concrete form in the ?taxonomy of symbolic policy? which he presents.

Vad är det här för låda? En Balthazarlåda! : En intervjustudie om pedagogers uppfattningar kring arbetet med färdigdefinierat material innehållande kemiska experiment.

Syftet med denna studie är att undersöka pedagogers uppfattningar kring ett arbete med Balthazarlådan som ett färdigdefinierat material innehållande enkla kemiska experiment. Det färdigdefinierade materialet, Balthazarlådan innehåller experiment om vattnets aggregationsformer och ytspänning, material till experimenten samt förklaringar till experimenten. Genom individuella semistrukturerade intervjuer så har svar på följande frågor sökts: Vilka tankar har pedagoger kring att arbeta med ett färdigdefinierat material, en låda med enkla kemiska experiment? Vilka fördelar respektive nackdelar upplever pedagoger med att arbeta utifrån ett färdigdefinierat material i förskolan? Vilka tankar har pedagoger om det färdigdefinierade materialet som en inspirationskälla kring arbetet med kemi i förskolans verksamhet? Resultatet visar att pedagogerna har arbetat med Balthazarlådan på olika sätt, antingen genom barnens intressen eller för att få barnen intresserade av kemi. Alla pedagogerna ser många fördelar att arbeta med kemi i verksamheten utifrån Balthazarlådan.

Materialval vid nyutveckling av mixerkanna till Ankarsrums assistent

Syftet med studien var, att på uppdrag av Ankarsrum Assistent AB, dels välja ett nytt material som ersättning till Polykarbonat i deras mixerkanna, dels undersöka om det går att minska längden på mixerknivens blad för att förebygga överbelastning av köksassistenten. De två frågeställningar som projektet bygger på var: Vilket material är bäst lämpat att efterträda Polykarbonat i Ankarsrum Assistents mixerkanna? Den andra frågan var: Kommer en minskning av mixerknivens blad kunna minska tiden, innan överbelastningsskyddet stänger av maskinen, utan att försämra resultatet?För att få en grundförståelse för mixerkannor och vad de förväntas klara skapades en områdesanalys som senare användes för att sätta upp material- och knivtester. Områdesanalysen användes även som grund till en kravspecifikation. Aktuella plaster och dess egenskaper sammanställdes i en materialöversikt.
