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.

The initial aim of the roll out of smart electricity meters in Sweden was to allow remote readings of the households? monthly electricity consumption for billing purposes. Since then the transition towards a smart grid has become a more prioritized matter. In the roll out of next generation smart meters more attention is therefore given to how the Distribution System Operator (DSO) can benefit from the meter through different smart grid applications. This study uses a qualitative research method to identify three general fields of application and 15 specific concepts corresponding to ways in which the DSO can create added value from the information provided by the smart meter.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.

Syftet med denna studie är att få större kunskap om NT-projektet, vilket är en kommunalsatsning på naturvetenskap och teknik, och om denna satsning gjort någon skillnad när det kommer till pedagogernas arbete med kemi i kommunens förskolor. Vidare kommer det också undersökas om de som arbetar med NT-projektet har någon särskild utbildning. Detta då det finns intresse att utvärdera NT-projektet och deras ?NT-lådor? samt införskaffa kunskap inom detta område inför framtida arbete inom kommunen ifråga. Kvalitativ- och kvantitativforskningsmetod har använts för att nå fram till frågeställningen.

The gender theory of Judith Butler is based on both philosophical and psychoanalytic notions of the self. Although greatly inspired by both early and contemporary psychoanalytic thinking, Butler has also questioned some of its core notions such as the meaning of gender complementarity and conceptions of desire. In a dialogue in Studies in Gender and Sexuality she discusses these and other theoretical and ethical issues with the influential psychoanalyst and gender theorist Jessica Benjamin. The exchange is a unique example of an attempt at dialogue and theoretical reflection between a prominent contemporary gender theorist and psychoanalyst. It reveals disagreements and theoretical difficulties I will show to be directly attributable to radical differences between Butler's and Benjamin's conceptions of the self.

In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.

Denna uppsats utgörs av en jämförande studie vars mål var att utröna huruvida åtta stycken utvalda investmentbolag på Stockholmsbörsen hade varit ett konkurrenskraftigt alternativ som sparform eller inte med avseende på risk och avkastning. Detta jämfört med SIX Return Index och den riskfria räntan under en tidsperiod på tio år, 2001-01-01 till 2010-12-31.Syftet med undersökningen var att den i slutändan skulle mynna ut i generella slutsatser kring investmentbolag som sparform utifrån de data som hämtats in från de berörda investmentbolagens hemsidor.Författarna kunde efter avslutad undersökning dra slutsatsen att investmentbolagen historiskt sett hade klarat sig mycket bra och kunnat uppvisa resultat som varken marknaden eller den riskfria räntan var i närheten av. Även om vissa av investmentbolagen hade presterat sämre än jämförelsemåtten så var dock den samlade bilden att de som grupp hade varit ett mycket fördelaktigt investeringsalternativ. Detta med en genomsnittlig totalavkastning som överträffade index med drygt åtta procent.  .

A speech-based material that early can assess a child's hearing is needed to provide an indication of a hearing impaired child's language development. Being able to identify and discriminate between different sounds is a requirement for interpreting speech. Hearing assessments that examine speech perception can therefore, unlike, for example, pure tone audiometry, examine a hearing impaired child's perceptual language skills and provide a basis for intervention.The purpose of this work is to evaluate a new auditory material on 3-year-old children. The auditory material is based on the Ling-6-sounds and the main question was which of the sounds in the test were adequate for test of discrimination. Furthermore, it was investigated how the test works with children aged 3:0?3:11 years and how age and gender affect the result.Twenty-four children aged 3:0?3:11 years were tested using a computer based test.

This essay set out to propose a problematic interpretation of the socio-cultural perspective on learning. Its purpose is to show how the socio-cultural perspective on learning defines the concept of knowledge in an incomplete way. The aim becomes then that of giving a more comprehensive description of this concept, and, to this end, to construct a new, broader pedagogic discourse. The investigation starts with a deconstructive analysis of Roger Säljö?s socio-cultural text in order to point out the incompleteness of the concept of knowledge.

The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.

ABSTRACT Our main objective with this essay is to provide a description of old people?s stories about aging. The essay is based on the empirical source of four qualitative interviews with older people over the age of eighty years young. The main goal is to inquire answers about; their time in the workforce; retirements; healthissues; media/advertisements; adolescence/youthfulness and attitudes. The following main questions have been dealt with: What do the elderly emphasize when they describe ageing? Are healthissues the prime subjects the elderly talk about? Do the elderly experience positive or negative attitudes towards ageing? What is their point of view of younger generations? In what way do they describe their years as workers? In what way do they describe aspects about their retirement? We reserved to consider the opinion of their own, to be the most valuable source in our study.

By exploring different forms of urban cultivation and looking into future gains of sustainability, I want to focus on unconventional and perhaps necessary ways of building, living and making a living. This will be made through study of literature on the topic.Urban cultivation could be anything from a pot of basil in the kitchen window to a city farm. The core of the concept is that the food is produced where it is eaten, in or in direct vicinity to the city and that it is produced ecologically. There will be many benefits, ecological, economical and social.The world is at a turning point right now where consumption patterns and the industry processed food are questioned and it is important that the things we consume are genuineand authentic. We want food that is locally and ecologically produced; food that we can trust.
