    Studies in ancient Egyptian anatomical terminology

    No full text
    In the 19 chapters of this thesis, many ancient Egyptian anatomical terms are carefully analysed with the objective of discovering their true meaning. The various current translations for a term are discussed in the introduction to each chapter. Then the lexicographical features of the terms are analysed. A term's position and associations in the anatomical lists often provides useful information and this is elaborated in a separate section. Particular attention is paid to the occurrences of a term in the medical texts and most medical case-studies containing the term are thoroughly analysed. Enormously valuable information about an anatomical term is often obtainable from non-medical texts and these are discussed separately. The conclusion to each chapter draws together all the findings and a decision is made as to the most precise meaning and best translation for the terms under consideration. At the end of Vol. I, some general observations concerning ancient Egyptian perceptions about the human body are made. At the end of Vol. II, a Lexicon of Ancient Egyptian Anatomical Terms and an enumeration of the anatomical lists are given

    Table1_Evidence of the Storegga Tsunami 8200 BP? An Archaeological Review of Impact After a Large-Scale Marine Event in Mesolithic Northern Europe.xlsx

    Around 8,200 years ago, the Storegga tsunami hit the coasts of the Norwegian and North Seas. This event is well known from wide ranging geological and palaeobotanical work undertaken over the last 30 years. Outside of attempts at palaeodemographic models, however, exploration of the social impact of the wave on Mesolithic hunter-gatherer societies living on the coasts of west Norway, the north and east British Isles, and around the southern North Sea basin have been less common. It has been widely assumed that the tsunami was a disaster–but what constituted a disaster for the Mesolithic peoples who lived through this event? What can we learn about life after natural hazards by considering the archaeological material from regions with distinct Mesolithic histories? This paper presents a review of evidence of the Storegga tsunami at Mesolithic sites from western Norway, the Northeast UK, and elsewhere around the southern North Sea basin. We consider the ways in which the social impact of the Storegga tsunami has been studied up till now and suggest an alternative way forward.</p

    Sexual lineage specific DNA methylation regulates Arabidopsis meiosis

    No full text
    DNA methylation controls eukaryotic gene expression and is extensively reprogrammed to regulate animal development. However, whether developmental methylation reprogramming during the sporophytic life cycle of flowering plants regulates genes is presently unknown. Here we report a distinctive, gene-targeted RNA-directed DNA methylation (RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates gene expression in meiocytes. Loss of sexual lineage-specific RdDM causes mis-splicing of the MPS1/PRD2 gene, thereby disrupting meiosis. Our results establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific epigenetic signature that controls gene expression and contributes to cellular function in flowering plants

    <p>Here the new data points are classed according to a majority vote of their <i>k</i> nearest neighbours, so q1 is classed as red and q2 as blue. Two variables are used in this example, although the same approach may be used with <i>n</i> dimensional data such as tri-axial accelerometer data.</p
