  1. 1. Polymerized Tubular Silicates in Lower Cambrian Carbonates – Biology or Chemistry?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Scott Green; [2022]
    Keywords : biosignature; tubular structures; Lower Cambrian; silica precipitation; bifurcating; biosignatur; rörstrukturer; Kambrium Serie 3; kiseldioxid utfällning; förgrening;

    Abstract : Shallow marine environments from the Lower Cambrian period were very different to shallow marine environments of today. Tubes of what was thought to be silica recovered from a partly dolomitized carbonate sample collected form a site near Indian Springs, Nevada could help further understand the chemistry and characteristics of such environments.

  3. 2. Deformable image registration using anatomical landmarks in tubular structures

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jenny Wingqvist; [2021]
    Keywords : Medical image analysis; radiation therapy; deformable image registration; anatomical landmarks; bronchial tree; vascular tree;

    Abstract : Cancer is one of the leading causes of death in the world, but advances in research and development of treatment methods is constantly ongoing to reduce the number of deaths and the amount of suffering. One of many approaches is radiation therapy, which uses high doses of radiation to kill tumors. READ MORE

    Abstract : Akuta njurskador (AKI) är ett samlingsbegrepp för olika tillstånd som innebär skada på njurarna med akut uppkomst. Många olika etiologier kan ligga bakom AKI hos hund, exempelvis förgiftning, infektion, blödning och sepsis. Njurarnas anatomiska strukturer påverkas olika beroende på vilken eller vilka etiologier som är inblandade. READ MORE

  6. 5. Fabrication of a light-weight SOFC using ceramic fibre paper as substrate

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Philip Löfkvist; [2015]
    Keywords : inorganic chemistry; solid oxide fuel cell; unmanned aerial vehicle; high temperature heat treatment; yttria stabilized zirconia; ceramic fibre paper; catator; nickel oxide; impregnation; paste manufacturing; ultra-sonication; ball-milling; optical microscopy; materials chemistry; scanning electron microscopy; materialkemi; Technology and Engineering;

    Abstract : A novel method for the fabrication of a light-weight solid oxide fuel cell (SOFC) has been evaluated at Catator. This was conducted in order to lower the weight and thus cost of an unmanned aerial vehicle. The main aim for this thesis was to achieve a thin, dense and crack-free electrolyte using a ceramic fibre paper as substrate. READ MORE
