Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Folkbibliotekens förmedling av Internetresurser: En undersökning av två mångkulturella länksamlingar.
The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.
Morfologisk och kemisk beskrivning av en svensk rabarbersamling (Rheum raponticum L.) :
SAMMANFATTNING
Mitt examensarbete utgör ett led i Nordiska Genbankens (NGB) uppgift att skapa en nordisk
s.k. ?core collection? av rabarber, Rheum rhabarbarum L. Samlingar finns även i våra
nordiska grannländer Norge, Finland, Danmark och Island. I Sverige har ett insamlingsarbete
av rabarber pågått under åren 2002 och 2003 för att komplettera en äldre samling.
Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :
The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking.
Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.
Folkbibliotekets pedagogiska uppgifter - en diskursanalys av fyra bibliotekstidskrifter
The aim of this Master's thesis is to examine the contemporary educational tasks of the Swedish public library as they manifest in Swedish library journals. Our main question at issue is: Which educational discourses are there? And in relation to our main question: how do the concepts of information literacy, lifelong learning and adult education relate to each other? Is there an antagonism between the public library's duty to supply fiction as opposed to non-fiction? and: What are the consequences of these discourses in the service provided by the library?Our theoretical starting-point is the discourse theory as proposed by Ernesto Laclau and Chantal Mouffe. We analyse 39 texts from four Swedish library journals: Ikoner, bis, DIK-forum and Biblioteksbladet. The analysis is done in two phases.
Utveckling av nytt koncept till processmaskin
Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.
Rhododendron ur undersläktet Vireya - något om dess karakteristika och användning i nordiska vinterträdgårdar :
Present essay aims to introduce the reader to central topics regarding Rhododendrons of subgenus Vireya. As a result of a donation, the Swedish University of Agricultural Sciences, received a collection of Vireya from a local amateur grower, Kurt Myllenberg. Since the subgenus Vireya is uncommon in Scandinavian horticulture, the study tries to establish conditions for successful growing.
The subgenus Vireya differ from the other Rhododendron species through mainly three characteristics: the presence of two tails, attached to each end of the seed; the ovary-style junction is tapering and the pedicels arises directly from a dome-like base and form an umbel and not a raceme. The subgenus is distributed mostly in the islands of Indonesia and New Guinea, but also from Malaysia to Nepal and in Australia.
Since Vireya species mainly grows as epiphytes in the tree canopies, they need high drainage and not too much water.
Urval vid digitalisering av affischer på Kungl. biblioteket
This thesis presents a study aiming to identify the selection criteria for the digitization of posters at the National Library of Sweden (Kungl. biblioteket). The theory is that cultural heritage institutions are empowered to decide how our cultural heritage is presented as they select what items (or, as in this study, posters) will be digitized. The poster is studied as it is an interesting media form which historically was an important means of communication. The poster can represent and reflect historical events and opinions in society.

The landscape architects are from the 18th century, the 19th century respectively the 20th century. The three persons are: Fredrik Magnus Piper, Knut Forsberg and Gunnar Martinsson. The landscape architects are brought up in chronological order in a chapter each where the person?s life, educations and work are described.
Medier på andra språk än svenska: En studie om det mångkulturella biblioteket
The purpose of this master?s thesis is to investigate how librarians approach to the multicultural collection development and which methods they use in providing library materials in minority languages. The questions to be answered are: which methods the libraries use when purchasing library materials in minority languages, how the respondents experience that the minority user groups needs are met in the library and how the multicultural competence of the staff is used in the libraries. For this purpose the qualitative interviews with 6 librarians in Gothenburg are conducted, mainly from the libraries in the immigrant-dense parts of the city, while the study being concentrated on 6 language groups of library users. The study?s theoretical framework is based on theories of multiculturalism, culture, identity and bilingualism.
Personas, en gökunge i användarcentrerad design : En undersökning av personas roll i samband med användarcentrerad design
The aim of this paper has been to examine personas role in the development phase and whether or not some of the criticism that have aroused against personas is valid or not. In this paper we examine the benefits as well as the downsides of working with personas both from a scientific point of view but also from the experiences of a small company located in the north of Sweden. Since personas much like many other powerful tools have pit falls aswell as do's and don'ts this paper looks to clarify what role personas should take aswell as how to minimize risk and maximize the usefulness of personas..

AbstractThe purpose of this essay was to determent if the authors? idea to replace a personal trainer with a training program, which is provided by software, is viable and if there is a market for such a product. The method that was used, included eight people who enrolled in a training program which were designed by the authors in Microsoft excel. The programs were based on principals of periodization, and included the phases: anatomic adaptation, hypertrophy, maximum strength and muscle definition. The training program was personal and based on individual goal setting.
Utfasning av farliga kemikalier - Vid Banverket och Vägverket
Large quantities of chemicals are used in all areas of society. The chemicals can be toxic and dangerous for the environment if used incorrectly. To protect people and the environment from dangerous chemicals, a good control of them and an active work to phase out hazardous substances in all areas where chemicals are present, are needed. Banverket and Vägverket handle in production a wide range of chemical products. Many of the products are dangerous to the environment, for those who work with them and to others who may come into contact with them.
Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid
Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).
