Produktionskalkyler för biobränslen :
This study is one of five that has been done based on Lunds Energi?s planned investment
in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be
supplied with biofuels.
In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage
sludge.
Generation Y - En kvalitativ stduie om hur generation Y hittar och bokar hotell med fokus på Sociala medier
AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA.

Utveckling av verktyg för jämförelse av kundanpassade och platsspecifika enskilda avloppssystem : Development of a comparative tool for custom-made and site-specific on-site sewage systems
REFERATÖvergödning är ett högst reellt hot mot många av Sveriges sjöar och vattendrag och inte minst mot Östersjön. Utsläpp av ej tillräckligt renat avloppsvatten och läckage av näringsämnen från jordbruksmarker är problem som länderna kring Östersjön måste lösa. Sverige arbetar både nationellt och internationellt med att förbättra Östersjöns ekologiska status. Riksdagen har satt upp flera miljökvalitetsmål som bland annat tydliggör att Sverige måste minska tillförseln av näringsämnen till sjöar och vattendrag. Orsaken är att dessa föroreningar är en bidragande orsak till övergödning.
Giftskåpet: Praktik och princip
The aim of this thesis is to examine the historical use of "poison cabinets", or restricted shelves, in Swedish libraries. Drawing upon the theories of Mary Douglas and Michel Foucault, it also seeks to sketch a cultural and ideological context of the practice; with the emphasis on social or mental hygiene, and disciplinary aspects. Through qualitative interviews as well as digitalized recordings of librarians active during the first half of the 20th century, actual examples of poison cabinets are presented. A closer examination is conducted of past collections at Lund University Library, and two large public libraries situated in Växjö and Sigtuna. The essay also investigates views on library censorship, controversial literature, and other related subjects reflected in th elibrary press during the period 1916-1979.
Urban kids- Funktionskläder för tuffa miljöer
Sammanfattning
Urban kids är ytterfunktionskläder för citybarn. Projektet har gått ut på att utveckla funktionskläder
för höst och vintersäsong som står i kontrast till outdoor- och sportföretagens estetiska värde. Målgruppen är modeintresserade stadsföräldrar som inte drar sig för att betala det lilla extra för att få en produkt som går i linje med deras livsstil. Syftet med arbetet var att ta fram underlag för att visa att det går att göra tekniskt funktionella ytterfunktionskläder för barn som inte klär sig sportigt.
Med hjälp av idégenereringar och en mood board, ett bildkollage för känslan som produkten ska utstråla, har ett koncept arbetats fram under stilnamnet ?rockig lekfullhet?.
Matarverk för Camcoil
By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.
Kvalitetssäkring av migreringsprocessen
I den här uppsatsen försöker vi författare reda ut problematiken med hur den s.k. migreringsprocessen kan kvalitetssäkras. Syftet är inte att nödvändigtvis komma fram till en fullständig lösning på problemet, utan att skapa ökad förståelse och förutsättningar för att lösa problemet. En migrering är, i arkiveringssammanhang, en flytt av data mellan lagringsmedium, filformat, systemmiljöer eller en kombination av dessa, för att kunna bevara ett digitalt material tillgängligt över generationer av datateknologi. Exempelvis en flytt av ett digitalt materials data från ett gammalt lagringsmedium till ett nyare, för att det gamla lagringsmediet är på väg att bli obrukbart.
Design av dörr till kaffeautomat : Designing a door to a coffee vending machine
This report was written as a result of a Bachelor Degree Project at the School of Technology and Society at University of Skövde spring 2007, together with Jede AB in Mariestad. The report covers the development of a door to a coffee vending machine that is under construction, and will in a chronological order describe the project from ideas to final product.The project started with a rather extensive feasibility study that thru market research and user tests sorted out the opinions of potential customers, concerning today?s available assortment. Technical areas concerning materials and manufacturing methods were also scrutinized for the consideration of the possibilities of a future production.The next step was to constructively generate ideas and thoughts that later on could grow to be potential solutions. After several weeks of hard work and pieces of good advice and recommendations from the assigner, four comprehensive concepts were built up.
Hantering av skadade styrstavar
The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.
Etnicitet och demokratisering i dagens Rwanda : En kvalitativ studie om etnicitet och demokratisering i Rwanda
The purpose of this study is to explain if the existence of ethnic groups in Rwanda has complicated its democratization and explain what opportunities Rwanda has to be democratized. To fulfill the purpose of the study, I intend to answer two questions: 1) Does the existence of ethnic groups obstructed democratization in Rwanda? and 2) What opportunities has Rwanda to be democratized? To answer the first research question Dahl's theory of subcultures and democratization is used and to answer the second research question van de Walle's theory of democratization is used in the region of sub-Saharan Africa. Literature used in the study are Dahl's Polyarchy and van de Walle Africa?s range of regimes and Freedom House annual reports.
FE-modellering av hjullast på sandwichpanel
This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.
Hallsta Pappersbruks virkesförsörjning
Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
