Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen
Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The
dynamics and paths of losses of phosphorus from arable lands are not fully understood.
It is known that phosphorus can be lost directly from plant material to water.
In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted
under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials.
In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
Drömmar om Glas : En skildring av skapandeprocessen av en kulturell mötesplats
Introduction: How to implement and integrate cultural aspects in strategy making and planning in order for cities and regions to reap both social and economic benefits has been widely discussed in recent years. This method of working with culture, both as an economic, as well as an identity strengthening tool has come to be labeled as cultural planning. But in order for these ideas about cultural projects and institutions to become a reality, something has to be done. This is where the entrepreneur enters.The Glass Factory, a newly opened cultural establishment in the heart of the Glass Kingdom in Småland, Sweden, became the subject of empirical investigation for this paper. As this originally was an initiative from Emmaboda municipality the planning and start-up procedure could be viewed as a cultural planning process.
Akustisk mätning av U-värde
This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions:
? Can U-value theory be combined with acoustic theories?
? Can the coefficient of heat be affirmed trough an acoustic measurement?
The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units.
The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory.
The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Att vara kvinna och styrelseproffs : En kvalitativ studie om kvinnor i svenska bolagsstyrelser
AbstractThe purpose of this thesis is to examine the professional female members of a board in listed companies. During the 21st century the issue of female quotation into the executive boards was discussed in both the media and politically due to womens underrepresentation in these contexts.The main purpose of this thesis is to examine the professional female members of boards stories of the role models they have, what characteristics have evolved, the views of others, and the self image. In addition, we want to investigate how women perceive themselves in a male-dominated field to identify how the female identity is created at work.Through a qualitative research in the form of personal interviews, we have gathered empirical material that forms the basis of our results. The answers from the interviews have been analyzed with the help of relevant theories and a social constructionist approach throughout the thesis. For our theoretical approach, we primarily chose symbolic interactionism, identity theories, and concepts such as the glass ceiling and gender strategies to analyze the data.The result of the survey shows that there are many elements that play into how women form their identities.
CFD-analys av flaskbottenkylning för glasformningsmaskin
Detta examensarbete har utförts på uppdrag av Emhart Glass Sweden AB i Sundsvall under vintern 2006/2007. Emhart Glass är en världsledande leverantör av utrustning, kontrollsystem och reservdelar för glasförpackningsindustrin, och företagets produkter har etablerats som världsstandard. Glasförpackningarna har en temperatur på 500-600 grader Celsius när de har formats. De hålls därför över en perforerad platta, kallad deadplate, för att kyla glasförpackningarnas bottnar så att deformation undviks när de sedan transporteras vidare för efterbehandling. Syftet med detta examensarbete är att utföra simuleringar av kylluftdistributionen för hålbilden i deadplate med hjälp av CFD ? Computational Fluid Dynamics.
Renovering av flerbostadshus - en studie om energieffektivisering och lönsamhet
In today?s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy system more energy efficient and consequently reduce the usage of energy resources. By 2020 the European Union should have reduced its energy consumption by 20 % compared to 1990?s level, and by 2050, 50%.
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
Effektivisering av materialflöde : En fallstudie vid Emhart Glass i Sundsvall
Patientövervakning och rondmöten är centrala aktiviteter i all sjukvård. Teknik som tagits fram för patientövervakning och rondmöten är relativt underutvecklad vad gäller överblick och mötesstöd. En fallstudie genomfördes med två observationer och en fokusgruppintervju på intensivvårdskliniken vid Linköpings universitetssjukhus. Syftet med fallstudien var att ta fram grundläggande informationskrav för att stödja sjukvårdspersonal vid möten och ronder i en intensivvårdssituation. Målet var att utveckla en övergripande design för ett digitalt arbetsbord.

Balancing packaging complexity by introducing platforms - A study at Carlsberg Breweries
Many consulting firms offer tailor-made solutions within complexity management, but these are not general frameworks built upon theories. Carlsberg are dealing with a large complexity within their one-way glass bottles, as they are growing by acquisitions, and are not attained enough economies of scale. This thesis balances the packaging complexity, with platform theory as a foundation. Twelve platforms were developed at Carlsberg, containing 21 bottles, and the calculated savings potential for applying these are EUR 28,9 million..
Burn-Out : En feministisk metod i glas
I work with and through glass and it´s from this field and tradition my work springs from. I am interested in how we look at and judge different expressions. I have been taught what visual expressions and shapes that are being appreciated and accepted and how to create objects like that. It should be clean, smooth, simplistic, and utterly pleasing. I recognize these attributes from what is being thought of as beautiful and desirable concerning the body.
Varför kommer inte fler kvinnor upp i hierarkin och gör karriär inom revision? Är det en tidsfråga eller finns det ett glastak?
The number of women in Swedish firms of accountant is not lower then the number of men, but when we compared the number of chartered auditors, the number of women are low compared to men. This is connected to the public debate that is mainly emphasising that there are no differences between men and women and therefore the sexes should be treated equal. The method used is a qualitative study and the primary data was collected through interviews. The respondents consist of members, women as well as men, from eighteen auditors in Malmö and Kristianstad. The result shows that both male and female characters are needed in the work on the firm of accountants.
