Sura Gamla Kyrka : analys av patologiska och skeletala förändringar hos sju individer
Seven individuals from Surahammar in Västmanland Sweden are analyzed for the appearance of pathological and skeletal changes. The graves, all from within the walls of a fourteenth century church, are dated from the Viking age to late eighteenth century. The aim of this scientific essay is to find pathological conditions by doing an osteological analyze, x-ray analysis, an osteoporosis measurement and letting orthopedists assess the individuals. The aim is also to say something about the individuals? general health and how they experience the changes they have in the skeleton.
Fornlämningskategori: : Fornborg - en diskussion om terminologi, forskningstradition och variation med fokus på de gotländska höjdanläggningarna
This thesis concerns the Gotlandic hill-forts (sw. fornborg) situated on a cliff or in an elevated position and which traditionally have been referred to as cliff-forts (sw. klintborg/höjdborg). The study derives from the notion that these monuments, diverse in size and shape, by archaeologists have been viewed and treated as a homogeneous category of ancient remains. The author?s key aim is to challenge this perception by identifying various subcategories from the 28 cliff-forts on the island.Ever since the archaeological discipline initiated the study of cliff-forts in the late 1800s and more or less to present day, the interpretations have been almost solely dominated by explanations of the military and defendable nature of them.
Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Ensamgravar och gravfält : olika begravningsmönster under romersk järnålder på Gotland
The aim of this thesis is to make a comparison between solitary graves and graves in grave fields from the Roman Iron Age on Gotland, Sweden. Differences in burial customs, morphology, dating, gender, age, grave-goods and social status are compared between 19 solitary graves and graves in three different grave fields in different parts of Gotland. An attempt is made to explain these differences and to discuss which functions the solitary graves had. Discussions about whether it is possible to distinguish social status and gender with the help of grave-goods are also made in connection to the determination of status and sex..
"Fallbacks" - betydelsen av vandringstid för Atlantlax (Salmo salar L.) som faller nedströms vandringshinder
In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.
Genus på menyn : Analyser av stabila kol- och kväveisotoper på skelettmaterial från Bjärbygravfältet från äldre romersk järnålder i Kastlösa på Öland
This paper deals with diet and gender in the early roman iron age in Sweden. Human bone and tooth material from the Iron Age cemetery at Bjärby in Kastlösa parish on the island of Öland have been analysed for stable carbon and nitrogen isotopes. 21 individuals were sampled. Where possible 4 samples were taken from each individual, from the first, second and third molar respectively and from one compact bone. By doing so it is possible, at least in theory, to trace intra-individual diets throughout life.
LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar
The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.
Aktivt Pansar : Att nå verkan med dagens vapensystem i morgondagens pansar
Då dagens vapensystem blir allt effektivare med högre penetration och större verkan är det inte längre möjligt att endast lägga på mer pansar för att få tillräckligt skydd. Fordonen blir för tunga och rörligheten påverkas negativt i allt för stor grad, därför börjar nu system för aktivt skydd slå sig in på marknaden. Dessa system söker aktivt av fordonets omgivning och skjuter ner inkommande hot såsom raketer och robotar och finns redan implementerade i en rad länder i vårt närområde. Infanteriets huvudbeväpning, som mot bepansrade hot traditionellt sett varit just robotar, raketer och granater, är i många fall verkanslös i mötet med aktivt pansar.Uppsatsen undersöker vilka möjligheter som finns att med den utrustning som dagens svenska försvarsmakt är utrustad med nå verkan i mål som är skyddade av aktivt pansar. De befintliga systemen för aktivt pansar Trophy, Iron Curtain och Arena har valts som exempelsystem.
Påverkar tidighetstyp fiberhalten hos rödklöver?
The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.
Graffiti i Karlstad : En konstform som väcker starka reaktioner
Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.
Kusten är klar : en undersökning av Gotlands bronsåldersstrandlinje i GIS
In this bachelor thesis an attempt is made to recreate the shoreline of Gotland during the Bronze Age. This has been done with the help of GIS to analyze remains dated to different periods of the Bronze Age that have been situated close to the coast. Case studies of three areas of the island have been made where dated remains together with typical Bronze Age remains like cairns and ship settings are analyzed with variables such as height over sea level and geological and topographical information. Contemporary datings from each case study have been compared to find a possible shoreline for both early and late Bronze Age. Two shorelines, one for the early Bronze Age and one for the late Bronze Age, have been created and tested on the three areas to see the placement of the remains in relation to these coastlines..

Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Som om min kropp inte är min...: Bilden av unga kvinnors sexualitet i svensk ungdomslitteratur
The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.
Västerbottens färgrika stenskatter : spatiala presentationer och analyser av skifferfynd i Västerbottens län
ästerbottens färgrika stenskatter - Spatiala presentationer och analyser av skifferfynd i Västerbottens län(The colorful stone treasures of Västerbotten ? Spatial presentations and analysis of slate artefacts in Västerbotten County)This essay pertains to the spatial distributions and analysis of slate artefacts in Västerbotten County, Sweden. The authors aim is to give answers the issues of what the distribution patterns of slate artefacts can tell us about the prehistoric humans in this area. By using GIS software and geospatial analysis the author strengthens the theories about separate interior and coastal economies, as well as the theory that the main share of production of slate artifacts are linked in the interior of the County, the author also refers to earlier research, both domestic and international. The theories of non-pragmatic preferences by the late Mesolithic and Neolithic people for red colored slate are also added to.
