  1. 1. The functional anatomy of the crocodilian heart

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Jennifer Karlsson; [2023]
    Nyckelord :Anatomy; Cardiac right-to-left shunt; Cog-teeth-like valves; Crocodilian heart; Foramen of Panizza; Hemodynamics; Left aorta;

    Sammanfattning : Crocodiles are ectothermic, intermittent breathing reptiles with low metabolic rates. Additionally, they are diving animals that can stay submerged for long periods, which poses special demands on their cardiovascular system. The crocodilian heart is four-chambered with completely separated ventricles, making it unique among other reptiles. LÄS MER

  3. 2. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ismail Yussuf Hassan; [2023]
    Nyckelord :graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Sammanfattning : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  4. 3. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Zahra Mohammadianrasnani; [2023]
    Nyckelord :GaN; Sputter epitaxy; Thin film;

    Sammanfattning : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. LÄS MER

  5. 4. Morphological characterization of the muscular ridge in non-crocodilian reptiles

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Wilma Sohlén; [2023]
    Nyckelord :Adaptation; Anatomy; Function; Haemodynamics; Muscular ridge; Reptiles; Shunting;

    Sammanfattning : The cardiovascular systems in ectothermic reptiles have long been studied and its development represent a transition state between a single- and a double circulation. This literature review focus on the typical-reptilian heart and therefore distinguishes between orders within the class of Reptilia. LÄS MER

  7. 5. A spatial analysis of Norwegian spruce cone developmental stages

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Alina Orozco; [2020]
    Nyckelord :;

    Sammanfattning : The Norway spruce Picea abies is an economically important export to the Swedish economy. There are a number of environmental and endogenous factors that impact the generation time of this species meaning that it can take 20-25 years for a tree to mature. LÄS MER
