62 90. TheModeling of Various Contraceptives and its Effect on theMenstrual Cycle This project investigates the mechanisms that promote drug delivery fromamodel implantable device and examines its effects on the menstrual cycle through mathematical modelling and simulation. The model demonstrates how follicle-stimulating hormone, luteinizing hormone, oestrogen, and progesterone fluctuate and interact. It also considers factors such as the remaining API in the device, the solubility of the API in the polymeric matrix, the degradation rate, concentration gradients, and other variables. These elements enable the comparison and evaluation of different implant configurations and their efficiency in API delivery, taking into account both short- and long-term effects. Additionally, the model compares the impact of biodegradable and semi-permanent methods on hormone levels during use and potentially after removal.

It focuses on refiningmaterial selection, infill structures, and digital workflows to improve printability and functional performance. The project will utilise CAD software such as SolidWorks and WrapStyler for modelling and simulation, along with PrusaSlicer for slicing optimisation. This research aims to contribute to the development of more customisable, sustainable, and accessible seating solutions through innovative digital manufacturing techniques.

As industries embrace sustainability, Closed-Loop Supply Chains (CLSCs) are vital for resource efficiency and waste reduction. CLSCs integrate forward and reverse logistics, enabling recycling, remanufacturing, and product recovery. This project analyses CLSC functionality, challenges, and optimisation opportunities through a simulatedmodel evaluating cost, efficiency, and environmental impact. Challenges like reverse logistics and remanufacturing costs will be addressed. Optimisation strategies will enhance sustainability and profitability, with a theoretical case study validating findings. The project aims to develop economically viable and environmentally sustainable supply chain models.
