Digitalisering av bilder vid två museer

The aim of this thesis is to describe digitization of images in two Swedish museums. We want to examine their reasons to digitalize; the administrative and organizational aspects of their work and how they handle the problems of preservation and access to the digitalized images. These problems will be examined through our main questions: Why do the museums choose to digitize their image collections? How are their work organized in terms of staff and economical matters? What kind of software do they use, and which technical solutions do they choose? Which preservation and access strategies for ensuring long-term preservation and access of the digital images do the museums work with? How do the museums select material for digitization? How do they handle the matter of discarding of materials? The study was conducted both by reading text material and interviewing personnel at the two museums. The museums? main reasons for digitization seem to be to protect fragile materials from deterioration and provide greater access to the collections.

Ett tillgängligt och användarvänligt boende : Anpassningsmöjligheter för människor med rörelsehinder och nedsatt rörelseförmåga

In this paper we have theoretically built a house designed for people with impaired mobility. Theessay begins with an introduction in which the purpose of the work, the methodology and thedepth-research part is presented. Then the layout that explains how we intend to adapt the housefor the demands detailed in the depth-research part is presented. In the same chapter variousstructural components, such as different floors and walls, are specified.In the selection of materials we have taken into account the criteria of our specialization andadaptation to the aesthetic aspects, where we evaluate materials based upon our wishes regardingtechnique and form. There are also other aspects that are important in the selection of materials,including that these are adapted to technical traits of the construction elements and installations.In a later chapter the technical installations such as ventilation systems, heating systems,electricity and sanitation are presented, where both technical and financial aspects are describedin detail.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.

Effects of peat and wood shavings as bedding on the faecal microflora of horses

The main purpose of this study was to determine the impact of bedding material on the faecal microflora of horses. Another objective was to investigate the hygienic and physical qualities of the bedding materials used and how these may change in the course of the trial period. The bedding materials used were sphagnum peat and wood shavings. Six horses had each material as bedding for a three week period in a change?over experiment.

Omkonstruktion av testrigg för småskalig ångsmotor

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

Internationell Upphandling av Byggmaterial : En studie över materialimportens potentiella tillämpning hos medelstora och stora byggentreprenörer

High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.

Krishantering : Granskning av krisarbete i grundskolan

My purpose in this paper is to study teachers' work in reading and writing in primary school and special school. I want to find out if they use the same methods, strategies and materials to help students learn to read and write. I will find out the answer to my purpose by performing two qualitative observation and two qualitative interviews. Lundberg (2010) is the researcher I relate to during my study. Through observation, I see how teachers work with students in the classroom during a lesson in the Swedish language. During the interviews, I received answers to how teachers work with language, the materials, methods and strategies they use. I found out that teachers use specific strategies when they help their students. They use a work material that is tailored to curriculum in Swedish language and it is based on the phonics method. .

Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök

In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

Återföring av växtnäringsämnen från avloppsvatten till åkermark : en bedömning av intresset för nya näringsrika produkter

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

Så funkar avdelning C: en kvalitativ undersökning av användbarheten av SAB-systemets religionsavdelning i dagens svenska samhälle

The purpose of this thesis was to find out whether the main class C (religion) in the Swedish classification system Klassifikationssystem för svenska bibliotek is well adapted to classify materials published in or imported to Sweden, and handled by Swedish libraries today. The questions we put to ourselves were:1. How easy to understand, and how useful is the main class C religion today?2. What, in the main class C, is satisfactory?3. What, in the main class C, is inconsistent, anachronistic or incorrect?4. What, in the main class C, is in need of change or renewal?The method that was used was a number of interviews with librarians and cataloguers. We have interviewed eight librarians from six different libraries, of different types, but all with a relatively large collection of religious materials.Though all of our respondents have expressed a feeling that all the major religions deserve equal treatment in the classification system and a similar division of space, after some pondering on the subject, our respondents have agreed that a larger space for Christianity is warranted considering the composition of the current collections and publication. Our respondents have in some cases expressed that there is a lack of instructions as to how the subdivisions of the main class C (religion) is meant to be used.
