Runstenar i kyrkomiljö, en länk mellan hednisk tradition och kristen tro? : En studie av senvikingatida runstenar anknutna till kyrkor i Jönköpings län.
The connection between rune stones and churches is a known phenomenon. Unfortunately, very little is known about the previous function of the church sites, and consequently very little is known about what the connection between rune stones and churches means. The purpose of this study is to examine the rune stones connected to churches in the administrative province of Jönköping, in an effort to ascertain their purpose, symbolism and function. The aim is to find out if the rune stones connected to churches were primarily or secondarily placed on the site where the church was later built, and why some rune stones were built into the churches. Further, the inscriptions and iconography of rune stones have been analysed, and also their relation to their immediate surroundings.
Förekomst av ultra-fina partiklar och partiklar ?10µm vid diatermianvändning med mobilt rökutsug : Jämförelse av partikelnivåer centralt och perifert på operationssal
Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland annat mutagena och carcinogena partiklar i inhalerbar storlek (partiklar ? 10µm).Ett första syfte med denna studie var att kvantifiera den mängd ultra-fina partiklar (UFP) och partiklar ? 10µm som operationspersonal exponeras för i operationsrummet, vid användande av diatermi med mobilt rökutsug.
Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests
Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.
?Det som skvalper omkring i hjärnan är det som kommer ut.? : En intervjustudie av kompositionsprocessen i folkmusik.
Syftet med denna studie är att ta reda på hur kompositörer inom genren svensk folkmusik idag går till väga när de komponerar ny musik, hur deras arbetsprocess ser ut och vilka arbetssätt de använder sig av. Det teoretiska perspektivet är hämtat från Stan Bennet och Max Grafs tidigare forskning om hur kompositionsprocessen ser ut för kompositörer inom konstmusikgenren. Ett didaktiskt perspektiv används också som utgångspunkt. Bakgrunden till arbetet baserar jag på tidigare forskning om kompositionsprocessen, forskning om gehörsmusik och kreativitet och idé-skapande. Jag ser även till vikten av att tränas i sitt divergenta tänkande som komponerande innebär.
Grodsamhällen längs vattendrag på Borneo : En identifiering av habitatkaraktärer viktiga för diversitet och abundans av grodor i tropisk regnskog
The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment
This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
"BÄTTRE BALANS I BOENDESAMMANSÄTTNINGEN" - FÖR VEM? : En studie om boendes upplevelser av social mixing i tre bostadsområden i Köpenhamn
Social mixing går ut på att ?mixa? befolkning av olika klasser i ett bostadsområde med syfte att förändra områdets sociala sammansättning. Syftet med uppsatsen är att undersöka social mixing som urban utvecklingsstrategi i Köpenhamn utifrån boendes egna upplevelser av sina bostadsområden. I Danmark definieras 29 bostadsområden som ?ghetton? utifrån kriterier rörande de boendes anknytning till arbetsmarknaden, ?icke-västliga? härkomst samt kriminalitet.
Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring
The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.
Det behornade ansiktet En transtextuell analys mellan Hjalmar Söderbergs Jahves eld och andra Moseboken
The aim of this study was to analyze the transtextual relationship between Hjalmar Söderberg's Jahves eld (The Fire of Yahweh, 1918) and the Book of Exodus. A limitation was set to just focus on the theme regarding the horned face of Moses, which Söderberg extensively discussed in his book, both through narrative and commentary. The methodological and theoretical approach could best be described as a qualitative text analysis where Gérard Genette's model of five types of transtextual relationships (intertextuality, paratextuality, metatextuality, architextuality and hypertextuality) was used in order to systematically classify the various relationships and in a thorough way relate the texts to each other.The analysis shows that the transtextual relationships are many and varied, and some appears to be more relevant to the study than others. Due to the composition of Jahves eld, its first part (?I österland, i fjärran tid?, most easily described as a paraphrase and pastiche of the Book of Exodus) can be identified as a hypertext to the Book of Exodus, while the second part (?Markels försvar?) is rather a metatext to both the first part and the Book of Exodus.
Religionsundervisning : - Genom vilka pedagogiska metoder
AbstractMy feature career as a teacher, for the early years of compulsory school, makes it interesting to finding out of how teaching religion can be donned. I am interested in what methods can be used for teaching religion That?s why my purpose aims to find out how five different teachers, of the early ages, works and what methods they use while teaching religion. My issue for this composition is: what methods, or to a point - methods supported by different teaching models, can be used for studying religion in compulsory school? Empirical and specialized literature points in the direction fore methods like storytelling, load reading, drama, group works, independent searching of information, working books and so on.
Inventering av vecklare i Svenska äppelodlingar
Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.
Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland
Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.
Good girls go to heaven, bad girls go everywhere- a qualitative thesis about the organization Empower and their sex working women in Thailand.
This thesis examines the organization Empower and their members, who consist of sex working women in Thailand. The purpose is to explore the more liberal point of view of prostitution and how the female members perceive Empower. Furthermore the study investigates if the organization can improve the sex workers empowerment. The study also delineates how these women reflect on their professional role as a sex working woman and whether the women relate to feminine discourses. The study is implemented in Chiang Mai, Thailand during the fall of the year 2010 and is based on qualitative methods like interview, focus group, observations and text analysis.
Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi
AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.
