?Båtnitar? : Analys och konservering av järnnitar från Birkas garnison
The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.
Att dela och sprida information. En studie med fokus på litteraturforskare.
The aim of this Bachelor?s thesis is to obtain understanding and knowledge about how literary scholars collaborate regarding information. Seven scholars have been studied in the aim to find out social and cultural elements which create particular prerequisites for their practice, with focus on information sharing. The method used has consisted of semi-structured interviews. The informants have been studied from a socio cultural and domain analysis starting point, which means that they are studied in the light of being members in their practice.
Äga rum: Offentliga rum betraktade i ett politiskt perspektiv, fallet Pristina
In order to fully grasp the phenomena 'City' we must understand its political structure as an integrated part of its physical structure and vice versa. This thesis focuses on one crucial element of the City, the public space, and discusses it in relation to the public realm, or sphere, of the City. The aim is to see if it is possible to conceive public space as a spatial dimension of power, and if so, how to analyse this. With the help of the theoretical tool of two ideal types of the configuration of public space, "The city as civic public life" and "The city as authoritarian control" an empirical study is carried out on the case of Prishtina, capital of Kosovo.Conclusions made are that function and use of a city's public spaces can be understood in relation to changes in the political climate of the society. Furthermore, a void in the asset of concepts offered by the ideal types is found ? and therefore also need for new concepts to describe and understand a public space undergoing a dynamic transformation, as being a part of a city in political transition..
?R KUSTN?RA ALK?RR I BOHUSL?N ETT ?BLUE CARBON? HABITAT?
In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
137Cesium i myrsamhällen i Gävleborgs län 24 årefter Tjernobylolyckan
24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.
Undersökning av självspridning av contortatallen i norra Sverige
Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions.
A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
Utvinning och analys av positionsdatafrån GPS-enheter : Jämförelse av metoder och program
In the field of IT-forensics you may often get to analyze different types of digital devices. One ofthese devices is the GPS navigation system. Nowadays GPS technology is getting more and morepopular and is included more frequently in different types of devices. With this article we want topresent the differenent obstacles and possibilites that a forensic investigator is presented with in thistype of investigation. We will be comparing different software suites and make use of forensic toolssuch as EnCase.The reader should get some understanding of the methods there are for analyzing one of these devicesand what problems that may occur in the investigation process.The article presents how the investigator can use different methods to gain information such as recentroutes, favourite destinations and other information that may be stored on the device.
Passage Retrieval: en litteraturstudie av ett forskningsområde inom information retrieval
The aim of this thesis is to describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How well do the approaches work in experimental information retrieval (IR)? PR is a research topic in information retrieval, which instead of retrieving the fulltext of documents, that can lead to information overload for the user, tries to retrieve the most relevant passages in the documents. This technique was investigated studying a number of central articles in the research field. PR can be divided into three different types of approaches based on the segmentation of the documents.
Webb 2.0-relaterad marknadsföring - Möjligheter och risker med marknadsföring i webb 2.0- relaterade webbtjänster
The purpose of this master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.
Standardiserad tillverkning av nätstationer
AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.
Sida vid sida för rättvisans skull : En studie av Sveriges främsta journalister på film ur ett genusperspektiv
The last ten years two major movies about journalists have been made in Sweden; Sprängaren and Män som hatar kvinnor. This study has looked closer at the heroine Annika Bengtsson and the hero Mikael Blomkvist from these two movies. Since movies do have great influence on how we see the world it is important to find out how these characters are being portrayed. Also, in a time when journalism is about to become a female dominant occupation it is relevant to see how the female journalist compares to the male. It is important to ensure that the films do not give a wrongful picture of male and female journalists.
Tilläggsisolering - lönsamt enligt en livscykelkostnadsmodell?
It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.
Kristinehamns provisoriska generalplan : En idéanalys av den lokala fysiska planeringen, åren 1940-43
The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.
Undersökning av titanföreningar för tillverkning av standarder vid användning av röntgenfluorescens
SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.
