Järnets förekomst i grundvattnet i isälvsavlagringar i Dalarna : Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Indexering av humanistisk litteratur och humanistiska databaser ? exemplet MLA International Bibliography

This thesis aims to answer the following questions: What type of vocabulary is used in the humanities? What does this implicate when it comes to indexing in the humanities? How do humanities scholars seek information and what type of information do they need? What consequences does this have when it comes to the development of humanities databases? How is the MLA International Bibliography organized? How does its indexing system ? CIFT ? work? How does the MLA International Bibliography correspond with the needs of the humanities scholar? The study shows that the type of vocabulary used in the humanities differs significantly from that used in the sciences. Therefore, information retrieval is often said to be problematic in the humanities when compared to the sciences. This is, however, not completely true. If consideration is taken to the different type of vocabulary used in the humanities, subject access proves to be more straightforward than has been generally recognized.

Studenters användning av akademiska tidskrifter: en källanalys av BandI-studenters magisteruppsatser 1999-2001

Previous research indicates that the academic journal in many cases is the most valuable and important source of information in scientific work. The aim of this study is to investigate students usage of academic journals in comparison to their usage of other document types, as illustrated by the citations given in LIS students master theses 1999-2001. By comparing the students use of LIS journals with the use of LIS journals by international scholars we also wish to examine whether students and scholars use the same journals in their work. The international scholars are represented by references given in LIS journals 1999-2001, recorded by the citation index Journal Citation Reports. Questions: 1.

Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

Nya förutsättningar en jämförelse mellan traditionellt och elektroniskt referensarbete.

The purpose of this master thesis is to investigate the differences between the traditional way of conducting a reference interview and the electronic way. The main questions of this thesis are: How does the electronic reference interview appear in comparison to the traditional one? How do the librarians experience the differences? Is quality affected in the electronic reference interview? Examples from Fråga biblioteket Ask the Library have been used in this study. The method used in the investigation is based on qualitative interviews in combination with studies of relevant and recent literature. The librarians interviewed all have experience from both traditional and electronic reference work.

Lexikonbaserad Cross-Language Information Retrival: Utvärdering av queryeffektivitet

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Döden till mötes : kriterier för att lokalisera avrättningsplatser på Gotland

The aim of this thesis is to investigate which criteria that can be used to locate execution sites on the island of Gotland, Sweden. The execution sites, which are used to test the criteria against, range in date from early medieval period to 1876 when the last public execution in Sweden took place. Why these criteria can be used will be discussed along with attempts to explain why they have been used frequently or not so frequent. The results show that the execution sites are most commonly located in clear view, near roads, on heights and on unfertile soil. Other criteria that appears less frequent, but that still can be used in the process of locating execution sites, are graves, crossroads and boarders..

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

Högskolebibliotekariers informationssökning : en studie i hur högskolebibliotekarier söker information till sig själva och för andra

The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.

En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion :

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

Framtagning av ett dimensioneringsverktyg för balkonginfästningar enligt Eurocode och ETAG.

The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.
