Rekreationsanpassade skogsskötselplaner för friluftsområdena Mellsta och Skräddarbacken i Borlänge :
This Master thesis is performed at the request of the forest company Mellanskog and the local municipality of Borlänge in Sweden and aims to establish recreational adjusted forest management plan for the areas of Mellsta and Skräddarbacken in Borlänge.
In all types of urban forestry it is very important that the management plan are accepted by the general public. To make sure that also these plans of future measures, pass in the public, interview studies have been performed in which the public wishes and interests have been examined and applied in the management plan.
To make sure that future measures in the forest may be accepted by the public when the forest harvester enters the woods, it is very important that a well functional work of information has been made. The people living close by the forest shall have been informed a couple of weeks before the time of measures and it must also be good information available that explains what is to be done and why.
Staden i ord och handling :
What is a city? What do we mean when we describe something as urban? In what way should we build the city so that we can achieve a good environment for our own generation and for generations to come? These questions are constantly of interest and they are frequently discussed. It is also important to have considered these questions when working with city-planning.
This essay contains a description of and reflections about the recurrent questions in today?s debate about the city and city-planning.
Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik
This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.
Berättelsens labyrinter : Interaktiv fiktion och dess narrativa aspekter
This essay examines the narrative aspect of interactive fiction. The study uses Janet H. Murrays analysis of the digital environment and the properties of it as procedural, participatory, spatial and encyclopedic. From this, her three characteristic pleasures in digital narratives - immersion, agency and transformation - are examined from the perspective of interactive fiction. The study also examines Nick Montforts analysis of interactive fiction as a potential narrative and a simulated world or environment.
Projektledares psykosociala arbetsmiljö inom offentlig verksamhet : En kvalitativ studie i Värmlands landsting
Thesis in project management, D-level by Chris Baldebo & Anders Persson spring semester2011. Tutor: Lennart Ljung. ?Project Manager's Psychosocial Work Environment in thePublic Sector ? A Qualitative Study in the Värmland County Council?.The purpose of this study is to examine how project managers in the public sector perceivetheir psychosocial work environment in a public organization. Therefore we have formulateda hypothesis based on the assumption that there exist differences in how project managersperceive their psychosocial work environment, depending on whether they work in public orprivate sector.Based on the objective, one research question has been formulated: How do projectmanagers active in the Pegasus program experience their psychosocial work environment? Tobe able to say something characteristic about the project managers psychosocial workenvironment our approach has been to interview five project managers.
Lost in translation : Bibliometrisk domänanalys av translation studies
The aim of this thesis is to analyze the academic discipline translation studies; the analysis centers upon bibliometric aspects, and is carried out chiefly by means of quantitative methods, enabled by the databases Web of Science and Scopus as well as by the corpus-linguistic software Wordsmith; however, this quantitative focus is complemented by auxiliary qualitative means of investigation, i.e. a discourse-analytically oriented study of a corpus of domain-endemic reviews.A number of core journals are analyzed in order to show what and whom are cited in translation studies, and, furthermore, what adjacent domains hold sway over it; attention is also given to influential authors, regions and languages operating within the domain. It is shown that the domain under scrutiny is quite differentiated, even fragmentary; the term pluricentric is used to describe this tendency towards sprawling. No superior authors (in terms of publication frequency) emerge, which arouses the suspicion that the domain may be conditioned by a hierarchical divide between journals and monographs. Furthermore, it is clear that translation studies is a eurocentric domain: European languages dominate.
Undersökning av retrobulbärområdet på hund med hjälp av ultraljud :
This study was performed in order to investigate the difficulty in diagnosing retrobulbar disease with ultrasound.
A retrospective study was accomplished to investigate the use of ultrasound in patients with suspected retrobulbar problems, and how often the examination is diagnostic. The computer based patient files, at the University of Agricultural Science in Uppsala, were searched for dogs with suspected retrobulbar disease. During 1999-01-01-2004-04-14, 14 patients fulfilling the search criteria were found. The patient records were studied, and the written reports from the ultrasound examinations were compared with the printed pictures from the examinations.
Förpackningsdesign i en varumärkesstärkande process : En fallstudie av varumärket Coca-Cola
Nowadays, packaging design is seen as a competitive tool and its importance for corporations is becoming increasingly apparent. The rivalry within homogeneous markets puts high demands on differentiation and the ability to create something more than the product itself. With this fundamental question, the soft drink industry has been examined and a case study of the brand Coca-Cola has been performed. The aim is to investigate how packaging design is used as a tool for strengthening a brand and to explore which additional values this contributes. In addition, the study observes the most important factors in the development of packaging design.A theoretical work of reference, consisting primarily of theories related to branding, design development and visual identity, has been developed to support the study.
Effektiva gränsorganisationer: en fallstudie av regionkontoret North Sweden European Office
Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and Västerbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.
Att beskriva och jämföra en expertgrupp och intensivvårdssjuksköterskors överensstämmelse i att detektera delirium hos intuberade, respiratorbehandlade patienter med sedering/analgesi, före och efter en utbildningsintervention : En kvasiexperimentell stud
The aim: was to describe and compare a group of experts and critical care nurses' agreement in detecting delirium in intubated, ventilator treated patients with sedation / analgesia, before and after an in house training intervention with the instrument Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).Method: A quasi-experimental study, one group pretest - posttest design. A convenience sample of 17 critical care nurses in a general intensive care unit included. To detect delirium the instrument CAM-ICU was used, 21 paired tests before and 22 after an educational intervention.Main Results: The results showed that after an in house training intervention sensitivity and kappa coefficient improved of the characteristic 1 "acute onset and fluctuating course," an improvement that was significant. In other features, and overall values were signs of numerical improvement and deterioration in sensitivity, specificity and kappa coefficient but no significant change.Conclusion: Implementing a new instrument for detecting delirium in clinical practice requires education and follow-up. A small sample of critical care nurses with varying ability to use the new instrument and the fact that patients' status may change rapidly making it difficult to draw any conclusions from this study.
Natten är naken och månlös : Subjektsinversion i Marie Unders 20-talslyrik
Like several of her female peers, Marie Under (1883 - 1980) has been denied the international acclaim she deserves. The earliest text on Marie Under in swedish told of her greatness, but in classical fallic maner reduced her poetic production by marking it with pathological symtoms. Though latter texts by author Enel Melberg have put a feminist perspective on Unders work, the theoretical complexity of her poetic images and language, and its polemic relation to contemporary literary currents, has yet to be recognised. This study will seek to portrait Marie Under and her poetry in this new light.The study moves from an installation of Marie Under in the modern discourse she so far has been estranged from, to an analysis of her earlier works (in the 1910?s and 1920?s).

Mellanlitteratur på bibliotek och i recensioner
This thesis investigates the reception of middle literature novels among critics in Swedish newspapers and at Swedish libraries. Works by three authors were chosen as representatives for middle literature: Helen Fielding, Nick Hornby and Tony Parsons. The investigation is based on interviews with librarians at the Gothenburg City Library, the total purchased number of books at public libraries in Sweden and analysis of Swedish newspaper reviews. The result is compared with theories by literary sociologists as Jofrid Karner Smidt, Janice Radway, Erland Munch-Petersen and Staffan Bergsten among others. It was found out that literary scientists and critics had a different way of looking at middle literature.
Nya kvinnor och ny samhällskritik : en feministisk läsning av Anne Charlotte Lefflers Tre komedier
My essay is about the latter period of Anne Charlotte Leffler?s authorship. In Part I of my essay, I describe her path from the 1880s, where she described femininity as a shortcoming, as writes Ingeborg Nordin-Hennel, towards the 1890s and towards describing femininity as a possibility. This development took place on two levels ? on an outer level, where all the woman writers in the late 1880s were influenced and where they were pushed out by the male writers, and on an inner level with Leffler herself.Her late literary works depict new and more independent types of women, and eroticism is given a more prominent position.
