Visioner på hällar : teorin om förändrat medvetandetillstånd på sydskandinaviska hällristningar under bronsåldern

In this paper I discuss the theory of altered states of consciousness. Some of the rock art of the san-people in southern Africa and the lakota people in South Dakota, USA have been inspired by experiences during trance. The question is if some of the rock art in southern Scandinavia also have been inspired by trance experiences, and if archaeological scientists by investigating this theoretical view might find a better understanding as far as the Bronze Age in Southern Scandinavia is concerned..

Musikfestivaler som turistiskt dragplåster : en fallstudie på Sweden Rock Festival

Cultural tourism and music tourism has developed into a significant and important part of the experience industry and it employs more and more people within the tourism industry. The purpose of this paper is to investigate which effects this can have on the local community.

Kartering och karaktärisering av bergmassor i Huddinge kommun : Utfört med RMRbas- och Qbas-systemet

Bergkaraktäriseringssystem såsom RMR och Q (Rock mass rating och Rock tunneling quality index) används ofta i förstadiet av ett byggprojekt för att ge en tidig uppfattning om bergmassans karaktär och kvalitet. Informationen underlättar planeringen och det fortsatta arbetet genom att påvisa korrekta arbetsmetoder och risker. De två vanligaste systemen för att karaktärisera berg är RMR och Q, vilka båda med hjälp av fältbedömningar och beräkning betygsätter den aktuella bergmassan. RMR och Q har här använts för att karaktärisera en bergmassa i Huddinge kommun inför en planerad byggnation. Resultaten av karaktäriseringen med de båda systemen skiljer sig åt på vissa platser vilket sannolikt kan förklaras med systemens olika tillvägagångssätt.

Att lyssna till det tysta : Fenomenologisk teori och hällbilder vid Motala ström

The survey takes its starting point in a critical evaluation of recent phenomenological approaches to rock art in landscape studies, foremost the works of Chris Tilley. The purpose is to present a phenomenological theory, based on the philosophy of Maurice Merleau-Ponty, which includes both motives, places and landscapes in a holistic interpretation. Bronze age rock art around Motala ström and the city of Norrköping is used to exemplify the theoretical discussion. When presenting the framework, emphasis is being laid on the bodily experience of rock art and place through the process of phenomenological intersubjectivity..

Klippbögar? : hällristningar ur ett LGBT- och queerperspektiv

The purpose of this thesis is to do an inventory of Swedish Bronze Age rock carvings depicting intercourse, and other sexual acts; applying gender traits on these in order to get a glimpse of what kind of normative outlook people at this time had upon sexuality. .

Fotogrammetrisk analys av kornstorleksfördelningeni erosionsskydd vid kraftverksdammar

This master thesis was made to investigate the possibilities of using the Matlab-basedsoftware Basegrain to determine grain size distributions of erosion protections onhydropower dams. Basegrain is a photogrammetric tool developed to generate grainsize distributions and other information about coarse flood sediments by analyzing adigital photo of the stone bed. The investigation was made by validating the ability forBasegrain to assess grain size distributions of various materials smaller than the blocksused in an erosion protection by comparing sieving results or manual measurementswith the results obtained by the program. A statistical comparison was then made bycomparing the results from sieving and the program. The possibilities of using thesame method on existing hydropower dams were then investigated by determiningwhether the method was practically viable or not.The results showed that Basegrain generated grain size distributions for coarse gravelthat were very close to the sieving results.

Stranderosion i Skåne

Erosion är en ständigt pågående process som formar om vårt landskap. Längs med kusten pågår ett samspel mellan vind, vågor, strömmar och sediment. Ett område kan sägas vara utsatt för erosion om mängden borttransporterat material är större än den mängd som avsätts. Det omvända kan också inträffa, det vill säga att stränder växer. Detta kallas för ackumulation.

Kunskap om dental erosion hos en grupp fotbollsspelare

Introduktion: Erosionsskador är ett växande problem bland barn, ungdomar och unga vuxna. Dental erosion har en multifaktoriell etiologi som består av endogena och exogena orsaker. Att erosionsskador på tänderna ökar kan bero på den höga konsumtionen av sura drycker bland barn, ungdomar och unga vuxna. Personer som idrottar kan löpa risk för dental erosion på grund av frekvent intag av sura sport/energidrycker men även till följd av påverkat salivflöde. Få studier har undersökt fotbollsspelares kunskap om dental erosion och dess konsumtion av sport/energidryck.Syfte: Att studera kunskapen om erosionsskador bland en grupp fotbollsspelande kvinnor och män.Frågeställningar: Vilken kunskap har fotbollsspelande kvinnor om erosionsskador? Vilken kunskap har fotbollsspelande män om erosionsskador? Vilken konsumtion har fotbollsspelarna av energi/sportdryck?Metod: Studien är en kvantitativ, empirisk, tvärsnittsstudie.Resultat: Totalt deltog 44 personer i studien, 29 kvinnor och 15 män.

How streaming media can be used in commercial mass
distribution

Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

Skydd mot yterosion i slänter av finmorän

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Lagring av kyla i bergrum : Undersökning av ett nedlagt oljebergrum

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

Fördelaktigt utrymme : ett försök till rekonstruktion av ett landskap och de attribut som kan utgöra det vid hällristningarna i Släbro, Nyköping Södermanlands län

In this paper I will attempt to recreate a prehistoric landscape surrounding the rock carving site of Släbro at Nyköping in Södermanlands län by using GIS. The main focus area is the river valley at Släbro and the six panels with rock carvings that have been dated to the Bronze Age. I?ll attempt to shed light on a long lost landscape. The shore line displacement have been extensive in this area a reconstruction will visualize the relationship between the panels, and their relationship to the surrounding landscape.

Erosionsskador hos barn och ungdomar

Aim: The aim of this study was to examine and explain the various methods available to rate the erosion damage, and on which teeth and tooth surfaces of erosion damage mostly occurs in children and adolescents.Method: A literature review was conducted, based on 15 scientific articles that have been reviewed, evaluated and analyzed. Articles were searched for in the database PubMed.Result: Six of the articles used the TWI (tooth wear index), which is an index to diagnose the tooth wear in the primary and permanent dentition. Eight articles used other indices as they considered that the TWI was not sufficiently developed to register the degree of tooth wear on some teeth. Tooth wear in the primary dentition occurs most often in the canines and incisors. Tooth wear in the permanent dentition was found in the literature to be mostly occurring on the occlusal / incisal surfaces of all teeth and tooth surfaces.LyssnaConclusion: There is no common index in the articles but many of them use the TWI.

Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.
