  1. 1. Dealing With Reservoir Effects in Human and Faunal Skeletal Remains : Understanding the radiocarbon dating of aquatic samples

    Författare :Jack Dury; Gunilla Eriksson; Kerstin Lidén; Peter Jordan; Johannes van der Plicht; Philippa Ascough; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Radiocarbon Dating; Reservoir Effects; Bayesian; Modelling; Palaeodiet; Stable Isotopes; Skeletal Remains; Collagen; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Sammanfattning : Archaeology relies on the ordering of past events to study cultural developments. This has traditionally been achieved by looking at the stratigraphic depths of materials relative to one another. In this way, chronologies of past technological progressions and stylistic changes can be built. LÄS MER

  3. 2. Silverberg i Järnbärarland. Bergshanteringens begynnelse i ljuset av Schmidt Testhammardateringar

    Författare :Richard Meurman; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; relative dating; Schmidt s Testhhammer; Differential test; Sala Silvermine; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Sammanfattning : This dissertation describes the development of a new method for relative datings of mines and quarrries ofpreviously unknown age. The method is known as the Testhammer dating method, and uses an instrument,Schmidt's Testhammer, originally invented in 1948 for measuring the solidity of concrete. LÄS MER

  4. 3. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

    Författare :Božo Frajman; Bengt Oxelman; Mats Thulin; Christian Brochmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

  5. 4. The crown of Arsinoë II. The creation and development of an imagery of authority

    Författare :Maria Nilsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Arsinoë; crowns; Ptolemaic; reliefs; Egyptian art; Egyptian religion; symbolism; female pharaohs; Hathor; God s wife; Edfu; Philae; Dendera; relative scaling; relative placement; concepts of time; post-colonial theory;

    Sammanfattning : This study deals with a unique crown that was created for Queen Arsinoë II. The aim is to identify and understand the symbolism that is embedded in each pictorial detail that together form the crown and how this reflects the wearer’s socio-political and religious positions.

  7. 5. Systematics in Sileneae (Caryophyllaceae) – Taxonomy and Phylogenetic patterns

    Författare :Frida Eggens; Bengt Oxelman; Magnus Lidén; Susan R. Kephart; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; RNAP; psbE-petG; ITS; rps16; relative dating; Rigidulae; Heliosperma; Arenosae; phylogeny; homoploid reticulate evolution; Silene linearis Decne.; Silene polyphylla L.; Hawaiian Silene; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : The focus for the first part of the thesis is on the systematics of species belonging to Silene subgenus Silene. Phylogenetic relationships are inferred from DNA sequences from both the plastid (the rps16 intron) and the nuclear (ITS, intron of the RPB2 gene) genomes. LÄS MER
