Fireball 2 : Energieffektiv fiber produktion
The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.
Utomhuspedagogik : En studie om lärares uppfattningar av utomhuspedagogik
In previous contact with secondary schools, we have noticed a dull setting for friluftsliv among teachers in Physical Education and Health. We suspected that both teaching and assessment are sometimes conducted in error. Under the provisions of Skolverket the teacher must involve all elements mentioned in the core content of the curriculum and the assessment of students' knowledge may be based only on what is expressed in the syllabus for each course. Research shows that the implementation of the curriculum have failed in the subjects investigated (Skolinspektionen, 2013:22). We have identified a gap of knowledge regarding the situation of friluftsliv in the course physical education 1.
Sjukgymnastik i skolan - behövs det?: en kvalitativ studie
The aim of this study was to investigate physical education teachers (PET) view of the needs of physiotherapy in compulsory school. Semi structured interviews were conducted with five PET. The study was carried out as a qualitative content analyse study. The interviews were coded in categories independently by the two authors. The categories were then brought together in four major categories: PET work situation, pupil health, physiotherapy and cooperation.
Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?
This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
Transporttider för vatten i närområdet till en vattentäkt : spårämnesförsök i en isälvsavlagring
When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.
"När katten är borta..." : En studie kring pedagogiskt ledarskap på distans

Karakterisering av bioslam för modellering av biogasproduktion
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood
Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

FysiskLojalitet vs CyberLojalitet? : Hur lojal är konsumenten mot den fysiska butiken då de väljer att övergå till e-handel av dagligvaror?
Background: Recently, the Swedish food culture has expanded by leaps and bounds. Interest in food and cooking has taken more space in the Swedish welfare state. Products and icons, such as organic free range chicken or Per Moberg have had greater impact on the way we consume food. Consumers have become increasingly aware of what they should and should not be eating. With an increased interest in food, supply and distribution channels have become increasingly important for the major grocery retailers (Board of Agriculture 2011).
