Affärsupplägg biobränsle Västerbotten : en undersökning av större biobränsleanvändares syn på biobränslemarknaden i Västerbotten
The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.
Inkludering kontra utanförskap inom Idrott & hälsa : En kvalitativ studie gällande hur elever med funktionsnedsättning upplever ämnet
The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
Effekter av fysisk aktivitet på recept
En litteraturstudie om effekter av fysisk aktivitet på recept av Anneli Björk-Andersson och Jenny Bylund, Institutionen för hälsovetenskap Luleå tekniska universitet. Tanken med studien var att ta reda på effekterna av fysisk aktivitet, hur man arbetar med fysisk aktivitet på recept i Norrbotten samt hur det ser ut i övriga landet. En litteratursökning som innefattade 45 artiklar, rapporter och uppsatser samt fem olika läns landstings webbsidor genomfördes. Några av landstingen har kommit långt i sitt arbete med fysisk aktivitet på recept och eftersom det var lättast att hitta material om dessa valdes de ut. Resultatet var tydligt, man har mycket att vinna på att vara fysiskt aktiv.
Integrering av kommunikation i ingenjörsutbildningar : Ett underlag för kompetensutveckling för universitetslärare vid KTH
The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.
Optimering av realtids-PCR för identifiering och kvantifiering av Humant T-lymfotropt virus
Human T-lymfotropt virus (HTLV) är ett C-typ onkovirus som tillhör familjen Retroviridae som huvudsakligen angriper T-lymfocyter och orsakar leukemi och andra autoimmuna sjukdomar. I den nuvarande kliniska diagnostiken används Enzyme-linked immunosorbent assay och ibland vid screeningsmetoden uppträder ospecifika reaktioner. På senare tid har flera metoder baserade på real-tids PCR utvecklats för att bestämma halten av virala genom i patienter. Syftet med denna studie var att sätta upp och optimera en realtids-PCR för detektion av humant T-lymfotropt virus typ-1 och 2. Inför optimering av realtids-PCR extraherades DNA från MT-4 och MO-T cellinjer. Under optimering av realtids-PCR användes SYBR Green och smältpunktsanalys där flera komponenter bl.a.

Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem
During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.
Integrering av ekosystemtjänsbegreppet i LCA-metodik : Kartläggning av möjligheter genom en fallstudie på pelletsproduktion
De nyttor som människan får direkt och indirekt från ekosystemen kallas ekosystemtjänster. Mänsklighetens påverkan på ekosystemen idag leder till degradering av tjänsterna och då mänskligheten ytterst är beroende av vad de tillför, är bevarandet av dessa tjänster viktig. Livscykelanalys, LCA, är ett väletablerat verktyg som används för att fastställa miljöpåverkan från olika produktprocesser men få ekosystemtjänster beaktas i LCA. Det finns därför ett behov av att vidare undersöka och utveckla möjligheterna att med livscykelbaserade metoder analysera påverkan på ekosystemtjänster.Huvudsyftet med denna studie har varit att undersöka om det är möjligt att integrera ekosystemtjänstbegreppet i LCA-metodik. Detta har kartlagts med hjälp av en fallstudie på pelletsproduktion, som bl.a.

Förslag till förnyelse av en villaträdgård i Limhamn, inspirerat av egnahemsrörelsens trädgårdar :
The population growth in Europe and with that in Sweden was enormous
under 18th century. The results became housing shortage in large part
of Europe.
Tight residency/ inhabited, poverty and emigration were series of social
questions in Sweden.
Private house (egnahem) as in the beginning was an idea from England and
Germany became a political measure and the answer at those miserable
social circumstances in Sweden.
The purpose with the private house (egnahem) was to help those new
people moved in to towns with place to live and counteract movers to
towns and emigration. With the governmental loan and land availability
that some municipalities and wealthy people contributed with, could
people get a place to live with the small garden.
The city garden (trädgårdstaden) with their future idealistic idea/utopia,
English gardens, ideas with roots in the old-fashioned gardens (allmogeträdgårdar)
and lots of books and periodicals were the source of inspirations.
From these the private house gardens (egnahemsträdgårdar) were
born.
Object for my study is my and my family?s own house in Limhamn,
south west of Malmö which was built in 1912 under private house gardens
era. The garden and the building have still trace and element from
the time of private house.
My suggestion is inspired by the private home style with a new thinking
design that answers to daily need and the busy life style; a rather easy to
maintain for green environment.
A more relaxing and peaceful garden with simple design, a garden
despite that it is surrounded by neighbours and streets invites in harmony
and dreams..
Offentlig upphandling av ekologiskt producerade livsmedel : Ludvika kommuns, Borlänge kommuns respektive Smedjebacken kommuns erfarenheter av gruppcertifiering enligt KRAV
The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.
Optimering av ett småskaligtvattenkraftsystem
This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.
