FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard
In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.
Europa som begrepp - då och nu : En komparativ studie av läroböcker
I started this project with the understandning that European hisory has become more important in government documents as a part in a larger European discourse, and that this fact is likely to be reflected in the chools textbooks. Therefore this essay deals with the task of comparing history textbooks over time trying to find changes. Firstly to find out how much space European history is afforded in the textbooks, and secondly how Europe is described and used in the textbooks. In my first task I will use a content analysis and in my second a conceptual analysis. My material consists of eight books and I have three pieces of older educational materials from the years 1949, 1954 and 1962.
Kreativitet som konkurrensfördel
Syftet med uppsatsen är att utreda hur en organisation kan främja och tillvarata sin kreativa potential. För att finna svar på frågeställningen tog vi till en början till oss litteratur inom kreativitets-, organisations- och förändringsområdena och identifierade därigenom åtta viktiga, återkommande faktorer för att främja och tillvarata kreativitet. Dessa är vision, kontinuitet, delaktighet, mångfald, öppenhet, resurser, kunskapsförvaltning och motivation. Litteraturstudierna gav oss underlag för en kompletterande empirisk studie. I ett andra led gjorde vi alltså en kvalitativ studie för att visa på en praktisk lösning av problemet.
Tv-spel ? självklart: Hermeneutisk studie om inställningen till tv-spel på fyra svenska folkbibliotek
The purpose of this thesis is to attain a deepened understanding concerning views on videogames at four Swedish public libraries, especially in relation to library practice and how videogames fit within this context. It also aims to provide insight as to why these libraries have included videogames in their collections and what thoughts were behind it. To fulfill this aim we conducted a qualitative hermeneutic study, using interviews as the main source of research material, but also written materials and a lecture on the city library of Malmö and how they work with videogames. The theoretical framework of the study is founded on Dorte Skot-Hansen?s and Douglas Raber?s theories on the values, roles and functions of public libraries.

Värmeväxlare med luftkonditionering för tvättstugor
The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.
Kvinnor som objekt, män som subjekt : En genusanalys av hur manliga respektive kvinnliga författare beskrivs i läroböcker avsedda för litteraturundervisning i ämnet svenska.
ABSTRACTIn this study I have analyzed, throughout a gender perspective, two textbooks Den levandelitteraturen and Upplev litteraturen which are purposed to be used as teaching materials inSwedish schools in the subject of Swedish when teaching the history of literature. The intentof this study was to provide a gender analysis of two textbooks and the focus was on thepresentations of female and male writers, because they have not been studied earlier. In thisstudy, a qualitative text analytic method was used to achieve the best results as possible.Theories used in this study were Yvonne Hirdman?s and Raewyn Connell?s theories. Hirdmanclaims that there are differences between men and women at different levels in the societywhile Connell believes that this is a myth because, according to her, men and women arepsychologically alike.
Vad händer i gränslandet? Människor, föremål och identitet i TV-programmet Gränsbevakarna Australien
The purpose of this paper is to study how the TV program Border Security: Australia?s FrontLine (Gränsbevakarna Australien) can be seen to reproduce networks of human and non-human actors. The aim is thus to investigate how boundaries between nations are upheld and how people, as a consequence, are discoursively categorized and what preconditions this create for people?sidentity- and meaning-making practices.The theoretical and methodical framework is built upon Bruno Latour?s work on Actor-Network-Theory, and discourse analysis inspired by Michel Foucault. The empirical material consists of two episodes of the TV program.
En sjuksköterskas följsamhet till basala hygienrutiner : En studie utifrån Theory of Planned Behaviour
Background: Nosocomial infections pose a big threat to patient safety and increased costs for society. An effective way of preventing cross-infections is to apply hygiene routines. Studies show that compliance to hygiene routines is low while there's a lack of knowledge about the best way of improving it. Aim: To investigate whether a conversation based on the Theory of Planned Behaviour (TPB) could influence a nurse's compliance to hygiene routines and whether it could benefit the understanding of a nurse's compliance. Method: A quantitative and qualitative method was used in the study and included one nurse.
Synen på kristendom en analys av läromedel i religionskunskap
The purpose of this thesis is to analyze the perception of Christianity in nine textbooks andidentify changes in-between them and over time. The content of the textbooks will also bediscussed in relation to the steering documents connected to each book.I have chosen to focus on three curriculums, Lgy 70, Lpf 94 and Gy 11. My researchquestions are: how Christianity is treated in textbooks in religious studies in relation to theperception of Jesus, God and man? What are the differences/similarities across time andlearning materials? In what way does the textbooks change with the syllabuses?Text consumption and discursive practices is analyzed with the help of a set of tools thatare based on the critical discourse analysis and Fairclough's three-dimensional model. Theimage of Jesus, if described by a textbook, is also analysed.Three textbooks were chosen from each curricula.
Svamparnas roller i svenska barrskogsekosystem : hur ser kunskapsläget ut hos några olika grupper människor?
Fungi are everywhere around us and recently, there has been
an increased interest in their role and importance in the forest.
The fungi have several strategies to acquire energy and nutrition; one example is a mutual symbiosis with trees and plants - another being dissolving organic materials.
Attempts have been made to better understand the circulation of nutrition in coniferous forests, and how fungi cooperate.
Trees and plants have adapted with mycorrhizae and are now interdependent which is important to consider in forestry.
A great number of fungi depend on dead wood and old trees to set fruiting bodies and spread further. These fungi also create environments for other species, such as birds and insects.
The vegetation of a forest is determined by a series of factors; tree species, how old the forest is, soil type, as well as the ability of the fungal spores to spread and establish. Furthermore, in determining vegetation, the fungi?s ability to compete in the soil matters. These factors are nearly unexplored.
Researching fungi knowledge and interest, a survey was distributed to five groups of people.
The groups included forest owners, high school teachers, high school students, senior citizens, and a fifth group - ?o he ? - consisting of people of mixed ages and backgrounds.
"Det är mesigt att läsa om musik": En studie av musikintresserade människors informationsvanor
The aim of this thesis is to investigate what information needs arise from the interest in music, which sources are preferred, how this information is sought and what part does the public library play in providing music materials. Brenda Dervin`s Sense-Making theory is what serves as a theoretic framework for this study. A qualitative approach was undertaken in the investigation and nine interviews were conducted with people interested in music. Findings indicate that different ways of acquiring information are used depending on the situation in which the information is needed and also what kinds of music people prefer. The main findings of this study suggest that people interested in music are keen to constantly discover new music to perform or listen to.
Islandshästar med hosta och/eller prestationsnedsättning : skiljer de sig åt jämfört med andra raser?
The purpose of the study was to investigate whether or not Icelandic horses are
less severely affected in clinical symptoms of cough or decreased performance
than other breeds of horses. A breed variation in chronic respiratory disease
severity was suspected based on clinical experience at the Institution for surgery &
medicine, large animal, SLU Uppsala. A retrospective journal study of 17
Icelandic horses and 17 Swedish Standardbred horses with chronic problems with
cough and/or decreased performance compared several measurements of disease
severity.
The clinical signs, physical examination and laboratory testing results compared
were respiratory rate, abdominal breathing, lung auscultation, endoscopy results,
broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All
parameters were available for all 34 individuals except for the blood gases, which
were analysed, in only four Icelandic horses and four Swedish Standardbred
horses.
The only parameters that appeared different between the two groups were
respiratory rate and pO2. The four Icelandic horses, which had blood gases
analysed, had more severe hypoxemia.
Formgivning och konstruktion av larmsystem för marint bruk
Roland Öhrvall, VD för Ro Rollytech AB, hade en idé om ett båtskydd som med hjälp av GPS skulle kunna meddela båtägaren om oönskad aktivitet, såsom stöld eller inbrott. Genom projektet ?Ett entreprenöriellt universitet? förverkligades idéen vid Luleå tekniska universitet. Den systemtekniska utvecklingen av larmet påbörjades 2005 och utfördes av EISLAB (Embedded Internet System Laboratory) vid LTU. Efter två års arbete var det yttre höljet det enda som kvarstod mellan idé och verklig produkt.
