Advancement of Simulation-Based Medical Training: Design and Implementation of a Self-Healing Natural Rubber Dummy Hand for Improving Cannula Insertion Proficiency
The simulation-based medical training field has shown improvements in specialized applications with the advancements of new technologies. Currently, there have been developed training tools for practicing cannula insertion techniques. These existing methods have several drawbacks and limitations. These existing materials have not been implemented with self-healing properties which have limitations when it comes to repetitive use. To address this issue, the development of a self-healing natural rubber dummy hand is required. Thus, this research aims to design and implement a self-healing mechanism for a natural rubber dummy hand to improve cannula insertion proficiency. Furthermore, this study mainly explores the compounding formulations and mechanisms that can be applied to developing self-healing materials.
Enhancing Detection Efficiency of Scintillation Materials Through the Development of Advanced Reflective Coatings
To optimize the performance of a scintillation detector, all the secondary photons (IR, visible, UV) that are converted after gamma – radiation is absorbed by the scintillator crystal should be directed to the photo multiplier tube (PMT) or the sensor. Then the PMT will be able to produce an effective response to show the detection. Practically, removing propagation losses is difficult and should be considered to produce an effective response by minimizing propagation losses. This study is to enhance the overall performance of the scintillator material, by improving detection (photon collection) efficiency by minimizing propagation loses, introducing a reflective coating.

Study on Temperature Effects on Biogas Production of Barrel Digester
The research conducted by W.M.M.L. Gunaratna explores the impact of temperature on biogas production using a barrel digester. The research conducted experiments by gradually increasing the temperature within the digester to observe changes in biogas yield. Starting at an average temperature of around 31°C, the temperature was increased to 40°C and 50°C. The study found that higher temperatures significantly enhanced the activity of methanogenic bacteria, leading to increased biogas production. This suggests that controlling the temperature within optimal ranges can substantially improve the efficiency and output of biogas systems. The findings contribute to the understanding of how temperature influences biogas production and provide valuable insights for optimizing biogas systems for sustainable energy solutions.
