  1. 1. Grain growth by Ordered Coalescence of crystallites in Ceramics : Grain Growth Mechanisms, Microstructure Evolution and Sintering

    Författare :Jianfeng Hu; Zhijian James Shen; Jekabs Grins; Viveka Alfredsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Grain growth and densification process play the two most crucial roles on the microstructure evolution and the achieved performances during sintering of ceramics. In this thesis, the grain growth of SrTiO3, BaTiO3-SrTiO3 solid solutions and Si3N4 ceramics during spark plasma sintering (SPS) were investigated by electron microscopy. LÄS MER

  2. 2. Endogenous Retroviral RNA Expression in Humans

    Författare :Lijuan Hu; Jonas Blomberg; Göran Friman; Francois Mallet; Uppsala universitet; []
    Nyckelord :Microbiology; Human endogenous retrovirus HERV ; HERVE; HERVW; betaretrovirus; gammaretrovirus; RNA expression; real time PCR; endometrium; endometriosis; brain tissue; reproductive tissue; ovarian cancer; ovary; neuroblastoma cell line; Mikrobiologi;

    Sammanfattning : Human endogenous retroviruses (HERVs) constitute about 8% of the human genome. There are around 4000 pol-containing retroviral integrations in the human genome, which makes it impractical to measure each of them separately. LÄS MER

  3. 3. Large-Scale Multi-Source Satellite Data for Wildfire Detection and Assessment Using Deep Learning

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wildfire; Remote Sensing; Active Fire Detection; Burned Area Mapping; Burn Severity Assessment; Sentinel-2; Landsat; Sentinel-1; Deep Learning; Semantic Segmentation; Image Translation; Skogsbrand; fjärranalys; aktiv branddetektering; kartläggning av bränt område; bedömning av brännskador; Sentinel-2; Landsat; Sentinel-1; djupinlärning; semantisk segmentering; bildöversättning.; Geoinformatik; Geoinformatics;

    Sammanfattning : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

  4. 4. Ideology and Symbolism in the Novels of Cormac McCarthy

    Författare :Fredrik Svensson; Magnus Ullén; Maria Holmgren Troy; Nicholas Monk; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Cormac McCarthy; Pierre Macherey; Marxism; ideology; affordances; symbolism; ecocriticism; English; Engelska;

    Sammanfattning : This study homes in on the ideological significance of American author Cormac McCarthy’s literary symbolism. Focusing in particular on the author’s tendency to merge hu­manity and the environment by way of metaphor, simile, and personifica­tion, the study demonstrates how the ethical and political import of this aesthetic is open to dispute.

  5. 5. Decoding the fossil record of early lophophorates : Systematics and phylogeny of problematic Cambrian Lophotrochozoa

    Författare :Aodhán D. Butler; Michael Streng; Lars E. Holmer; Russell Garwood; Maggie Cusack; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Chengjiang; Lagerstätte; Cambrian Explosion; palaeobiology; stem-group; entoproct; phoronid; tommotiid; exceptional preservation; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Sammanfattning : The evolutionary origins of animal phyla are intimately linked with the Cambrian explosion, a period of radical ecological and evolutionary innovation that begins approximately 540 Mya and continues for some 20 million years, during which most major animal groups appear. Lophotrochozoa, a major group of protostome animals that includes molluscs, annelids and brachiopods, represent a significant component of the oldest known fossil records of biomineralised animals, as disclosed by the enigmatic ‘small shelly fossil’ faunas of the early Cambrian.
