  1. 1. The functional anatomy of the crocodilian heart

    University essay from Linköpings universitet/Biologi

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Strukturkemi

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

    Abstract : 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

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Zahra Mohammadianrasnani; [2023]
    Keywords : GaN; Sputter epitaxy; Thin film;

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Wilma Sohlén; [2023]
    Keywords : Adaptation; Anatomy; Function; Haemodynamics; Muscular ridge; Reptiles; Shunting;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alina Orozco; [2020]
    Keywords : ;

    Abstract : 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. READ MORE
