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.

Implementering av miljökvalitetsmål i mindre kommuner : - En fallstudie av Torsby kommuns arbete med att implementera delmålet Planeringsunderlag

The aim of this dissertation is to examine why smaller municipalities[1] in Sweden experience difficulties when implementing the 16 environmental objectives that are designed to solve Sweden's environmental problems.The theoretical framework used for this dissertation is implementation theory which provides three conditions that need to be met in order to have a successful implementation.  These three conditions have shaped the research questions that examine if Torsby municipality has the "understanding," "ability" and "will" needed to implement the decision correctly.  The dissertation employs a case study method to examine why Torsby municipality has experienced difficulties implementating the target: programmes and strategies for planning, which is an interim target to environmental objective number 15: A good built environment.  Qualitative text analysis and interviews with politicians and civil servants from Torsby municipality and the county administration board of Värmland have been conducted in order to answer the research questions.   The material used for this dissertation is mostly from the government bills that are the foundation of the Swedish environmental policy and the documents and reports about the environmental objectives that the National Board of Housing, Building and Planning (Boverket), the Swedish Environmental protection agency (Naturvårdsverket), and the Environmental objectives council (Miljörådet) have released.The result of this dissertation supports previous research which has shown that smaller municipalities have problems implementating the environmental objectives due to a lack of financial resources. This dissertation also shows that the problems can be due to a lack of understanding the purpose of the objectives.  This leads to a lack of political will to implement the objectives.  Since the municipalities do not have the political will to implement the objectives the appropriate resources needed for a successful implementation are not appointed and therefore the municipalities are not able to fully implement the environmental objectives. [1] Municipalities with less than 20 000 inhabitants..

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.

OneCore

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

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.

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.
