Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde
The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..
Hur tre epistemologiska diskurser och hur synen på kunskapsorganisation inom dem manifesteras i text
Our purpose is to analyse three different epistemological discourses that exist in the social practice, Library and Information Science LIS, using the strategy for interpretation from the mimesis model by Paul Ricoeur and the terms from the critical discourse analysis by Norman Fairclough. The aim is also to explore there different views of knowledge organisation. We review previous research involving epistemology, knowledge organisation and discourse analysis in LIS. These show that there are many different epistemological standpoints and that later research has shown a more critical and sceptical state of knowledge organisation than earlier traditional positivist ideals. Discourse analysis is described as an important theory and method in LIS.
Centrum för lättläst : Ur ett domänanalytiskt perspektiv
The aim of this two years master thesis in Library and information science is to study the foundation Centrum för lättläst and its work regarding information use with focus on information structures and information needs. The aim is also to examine how Centrum för lättläst cooperate with Swedish libraries to promote the work concerning people with reading disabilities. This master thesis applies a domain analytic theory and method inspired by Birger Hjørland. The domain analysis is confined to examine ontology, epistemology, sociology, empirical user studies, document and genre studies and studies of structures and institutions in scientific communication. The main source material consists of information from the homepage of Centrum för lättläst.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
Nä?r ä?ldreomsorgen blev galleria och den ä?ldre kund : En kritisk diskursanalys av informationsbroschyrer om ä?ldreomsorg
The purpose of this bachelor thesis is to examine the views of the elderly and the caregivers that appear in brochures for the elderly and the discourses that can be found within. The data that the study is based on was collected and analysed using content analysis and Faircloughs (1992) critical discourse analysis. The theoretical frameworks that have been used are social constructionism, critical discourse analysis, assortment and protest, and New Public Management. The results showed two images of older people (I) the elderly as active and autonomous and (II) the elderly as passive and in need of help. The results also showed two pictures of the caregiver (III) the caregiver and NPM, and (IV), the non-profit care provider as a complement.
Igenkänning, lånat gods och minnesfragment : En tematisk studie av de narrativa egenskaperna i tre bilder av Karin Mamma Andersson
The purpose of this thesis is to examine the narrative elements in three of the Swedish artist Karin Mamma Anderssons paintings and try to see what kind of stories that might be hidden in these paintings. I have chosen three different themes as tools for this study. They are: the meaning or the importance of the titles, painting as a medium and the narrative elements or components in the paintings. Furthermore I also use the semiotic method in my analysis based on the ideas of Roland Barthes combined with a feminist theoretical standpoint with a gender perspective. This means my study is based on the reception of these images and what kind of message they might carry.
Betavärdet som riskestimat
As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.
"Om jag kunde drömma, skulle jag drömma om dig" : En genusstudie av Stephenie Meyers Twilight-karaktärer
One task of school is to counteract traditional gender patterns. Literature is an actor which can affect people?s perceptions of what is feminine and what is masculine. It can therefore be worth looking at the works of fiction that are available for pupils in school. A book that is popular among children and adolescents is Twilight (2007).
XRF-analys av förorenad mark : undersökning av felkällor och lämplig provbearbetning
X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to affect the results of measurements.The purpose of this thesis is to bring a deeper understanding of how different factors affect the results of XRF-analysis. A large number of measurements have been made with the instruments Niton XLt 700 and Niton Xli 700. Results from measurements of lead, zinc and copper have been analysed.This study has shown that a greater moisture content will give a lower measured concentration for the same sample.

Rekgrupperna i de svenska ingenjörbataljonerna : Är de bara ögon i terrängen eller har de möjlighet att bita ifrån?
This paper describes the Swedish reconnaissance squads in the engineer battalions, their equipment, tasks and organization. An analysis is made to compare the present weapons and fire power of the reconnaissance squad with an extended weapon alternative. The analysis focuses on the abilities effect, protection and movement in different situations typical of a reconnaissance squad.The facts that are presented in this paper are mostly founded on the new field manual FältarbR Dyktjänst 2007, which regulates much of the reconnaissance activities. The aim of this paper is the making of a contribution in the developing progress of the new field manual and the reconnaissance squads in Swedish engineer battalions.The result of the analysis shows that the extended weapon alternative would be an asset..
FEM?modeller för expansionsanalys av piplines
REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.
Introduktion till Socialkonsekvensbeskrivning - SKB, samt metod vilken kan användas inom SKB
Often, the green is handled as an opposite to the built, but if it could be seen as a part of the built and the society, the planning will be easier to handle. The thesis work wants to create a method that treats villages in an analytic way in a context; with green, blur, grey and all the other colors that together are the completeness.This master's thesis is made to be used as foundation in detail plannng in the municipality of Örkelljunga. Target audience is on one hand those who work with planning and green matters in Örkelljunga municipality, but also other planners who work with landscape.Literature in the field of green city planning has been studied and 30 methods for analysis have been valued. The method for analysis that has been used in this work is a merging of ten different methods and has included literature studies, sketches, interviews and work on spot. The ten methods are consciously chosen to together make one comprehensive and true image of the village, as far as it is possible.
Multikriterieanalys av potentiella konflikter vid markanvändningsplanering - Naturstenbrytning i Lysekils kommun
The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.
Södras gröna skogsbruksplaner ur ett landskapsperspektiv :
The aim of the "Green forest management plans" is to help forest owners to reach the
environmental goal of the forestry act. But are they able to do that? Is it possible to plan preservation of species on single estates? How do single-estate-plans differ from a landscape analysis and how can the landscape approach be used in operative planning? This work was initiated to give an answer to these questions.
This study was made in a landscape of 4200 ha in Östergötland county, south-eastern Sweden. A lanscape analysis was made and then compared to the Green forest management plans in the same area. The nature conservation areas (areas that were set aside to be managed with environmenatl goals) differed quite a lot between the two alternatives.
