1. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique
University essay from KTH/HållfasthetsläraAbstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

2. An Analysis of Growth and Aging in a Tyrannosaurus rex through Histology and Synchrotron Micro-Tomography
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Size comparisons, skeletochronological, and palaeohistological studies have been major contributors in the past decades to expand our knowledge on how dinosaurs, including Tyrannosaurus rex, lived and grew. Historically, size comparisons have been used to establish a relative order of age, and thin sections have been used to study the palaeohistology and skeletochronology, as well as establish growth curves, to construct more quantifiable age determinants.

3. Diversity and Evolution of Silurian Radiolarians
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The three approaches followed herein aim to improve our understanding of the paleobiodiversity andevolution of Silurian radiolarians. The first approach provides an exhaustive taxonomic description ofan entirely new radiolarian fauna recovered from two sections of the Cape Phillips Formation in theCanadian Arctic which accumulated in two different paleoenvironmental settings.

4. The Primitive Antiarch Yunnanolepis from China : A Microtomographic Study
University essay from Uppsala universitet/PaleobiologiAbstract : 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
