  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. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Björn Walter; Stefan Piiroinen; [2021]
    Keywords : Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Abstract : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

  4. 3. Cardiovascular effects of exposure to biodiesel exhaust

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Youna Marc-Derrien; [2021]
    Keywords : photoplethysmography; electrocardiography; signal processing; pulse decomposition analysis; heart rate variability; pulse transit time; biodiesel; arterial stiffness; Technology and Engineering;

    Abstract : Context: Urban air pollution is considered a significant factor contributing to increased respiratory and cardiovascular mortality in cities. Many studies focused on the relationship between exposure to diesel exhaust and human health effects, demonstrating the toxicity of such gases. READ MORE

  5. 4. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jesper Hägglund; [2021]
    Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

    Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

  6. 5. Software Platform for Design and Management of Real-time Data from Microneedle-based Wearable Sensors : A front-end (iOS) and a server-side (Node.js) implementation for an IoT system

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Arasp Keighobad; Faruk Bugra Demirel; [2021]
    Keywords : Microneedle-based sensors; IoT; REST; MVVM; Mikronålsbaserade kliniska sensorer; IoT; REST; MVVM;

    Abstract : Wearable Microneedle (MN)-based sensors have been developed in a joint collaboration between KTH and KI in order to potentially replace invasive clinical tests such as arterial blood gas measurement. For research purposes, an IoT software platform is needed for convenient real- time observation/calibration of raw data, and observation of calibrated concentrations. READ MORE
