2. 1. Promise, Protection, and Prosperity. Aspects of the "Shield" as a Religious Relational Metaphor in an Ancient Near Eastern Perspective. An Iconographical and Textual Analysis

   Author : Arne Wiig; Centrum för teologi och religionsvetenskap; []
   Keywords : HUMANIORA; HUMANITIES; Theology; Assyria; Egypt; Hebrew Bible; Ancient Near East; relational metaphor; shield metaphor; Metaphor theory; shield; Teologi;

   Abstract : This thesis discusses the religious metaphorical use of different words for "shield" in the Hebrew Bible and Egyptian and Assyrian literature. The literary contexts in the analysis are delimited based on the observation that they share a similar view of divine intervention in war and an analogous view of the enemy. READ MORE

4. 2. Crustal evolution of the Arabian–Nubian Shield : Insights from zircon geochronology and Nd–Hf–O isotopes

   Author : Fitsum Girum Yeshanew; Victoria Pease; Martin J. Whitehouse; Robert J. Stern; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gondwana; Arabian–Nubian Shield; Azania; zircon U–Pb–O–Hf isotopes; Nd isotopes; Cambrian Sandstones; juvenile; pre–Neoproterozoic; reworking; Geology; geologi;

   Abstract : The Arabian–Nubian Shield (ANS) represents a major site of juvenile Neoproterozoic crustal addition on Earth and documents Neoproterozoic tectonics bracketed by two supercontinent cycles, namely the fragmentation of Rodinia and the amalgamation of Gondwana. There is general consensus that the ANS formed by juvenile magmatic arc accretion and subsequent shield–wide post–tectonic magmatism. READ MORE

5. 3. End-Shield Bridges for High-Speed Railway : Full scale dynamic testing and numerical simulations

   Author : Hesham Elgazzar; Jean-Marc Battini; Mahir Ülker-Kaustell; Morgan Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.

6. 4. The Mesoproterozoic Hallandian event - a region-scale orogenic event in the Fennoscandian Shield

   Author : Linus Brander; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fennoscandian Shield; Hallandian orogeny; Eastern Segment; Protogine Zone; U-Pb geochronology; zircon; baddeleyite; Nd-isotopes; Hf-isotopes; tectonic model;

   Abstract : The Sveconorwegian Province occupies the southwestern part of the Fennoscandian Shield. The easternmost tectonic unit of the Province is the 1710-1660 Ma parautochthonous Eastern Segment, which bears the imprint of at least two metamorphic events; the 1460-1380 Ma Hallandian and the 1150-970 Ma Sveconorwegian.

7. 5. Analyses of Seismic Wave Conversion in the Crust and Upper Mantle beneath the Baltic Shield

   Author : Sverker Olsson; Roland Roberts; Hans Thybo; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; converted waves; Moho; upper mantle; Baltic Shield; tomography; anisotropy; receiver function; Geofysik;

   Abstract : Teleseismic data recorded by broad-band seismic stations in the Swedish National Seismic Network (SNSN) have been used in a suite of studies of seismic wave conversion in order to assess the structure of the crust and upper mantle beneath the Baltic Shield. Signals of seismic waves converted between P and S at seismic discontinuities within the Earth carry information on the velocity contrast at the converting interface, on the depth of conversion and on P and S velocities above this depth.
