  1. 1. Evolution of the Vascular Pattern in Mammals : Using Synchrotron Imaging to Visualise Hidden 3D Structures

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jasper Ponstein; [2017]
    Keywords : Secondary ossification centres; Mammalia; vascularity; limb-bone evolution; Sekundära ossifieringscentra; däggdjur; vaskuläritet; lembensutveckling;

    Abstract : The morphology and histology of long bones are important tools for understanding tetrapod locomotion and growth. In mammals, the epiphyses of long bones ossify from a secondary centre of ossification. The consensus is that vascular canals are closely tied to the formation of these centres. READ MORE

  3. 2. Segmentation, Analysis, and Modelling of Microstructure in Cortical Bone, based on X-ray Microtomography

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Elin Törnquist; [2017]
    Keywords : Cortical bone; Biomechanics; Segmentation; K-mean clustering; Microstructure; X-ray Microtomography; Mathematics and Statistics; Medicine and Health Sciences; Technology and Engineering;

    Abstract : The microstructure in cortical bone greatly affect the toughness of the bone and the crack propagation during fracture. The two main structural features, Haversian canals and osteons, have been previously studied in order to increase the knowledge of the biomechanics of bone. READ MORE

  4. 3. Classification of Drill Core Textures for Process Simulation in Geometallurgy : Aitik Mine, Sweden

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Glacialle Tiu; [2017]
    Keywords : ore texture; texture classification; Machine Learning; drill core photography; scanning electron microscope; X-ray microtomography; mineral mapping; stereology;

    Abstract : This thesis study employs textural classification techniques applied to four different data groups: (1) visible light photography, (2) high-resolution drill core line scan imaging (3) scanning electron microscopy backscattered electron (SEM-BSE) images, and (4) 3D data from X-ray microtomography (μXCT). Eleven textural classes from Aitik ores were identified and characterized. READ MORE

  5. 4. Morphological differences in the apposition eyes found in different species of stingless bees (Meliponnini: Apidae: Hymenpotera) with X-ray microtomography

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Viktor Håkansson; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : As the most diverse group of animals in the world with more than a million describes species, insects varies in many aspects of their ecology. Bees are insects that can be found in many different habitats across the world. READ MORE

  6. 5. The Primitive Antiarch Yunnanolepis from China : A Microtomographic Study

    University essay from Uppsala universitet/Paleobiologi

    Author : Jessica Grahn; [2016]
    Keywords : placodermi; microtomography; 3D model; mikrotomografi; 3D-modell;

    Abstract : Placoderms appeared in the Silurian period and rapidly evolved and dominated the waters during the Devonian period. Among the earliest of the placoderms are yunnanolepids, a primitive form of antiarch from the Early Devonian of China and Vietnam. READ MORE
