“…The shape and geometry of other components such as plates and screws were also adopted from other previous researchers [5], as shown in figure 1(b) and 1(c). Stainless steel material of type AISI 316 was chosen as the plate and screw material, with the mechanical properties shown in tabel 1 [6]. AISI 316 stainless steel is the most widely used material because it is IOP Publishing doi:10.1088/1742-6596/2739/1/012046 3 more economical in terms of cost, has high biocompatibility, and also has corrosion resistance to the physiological salt content in the human body [7].…”

The fibula is a bone with a small cross-sectional area that is located in the calf parallel to the tibia bone and includes part of the lower leg. Technically, this bone only receives a load of approximately 15% of the total load received by the lower leg. However, under certain conditions, the fibula can be broken and require medical attention to repair it. The most common medical solution to improve this condition is to install an internal fixation. The main function of internal fixation is to keep fractured bones stabilized and in alignment. When the internal fixation is in place, the internal fixation will receive tension, at least by the patient’s body weight while supporting the legs. The magnitude of the received stress value will certainly influence the strength of the material from the internal fixation. Experimental studies are very difficult to carry out. Therefore, in this study a numerical analysis of the stress distribution on the internal fixation of the fibula bone was carried out, using the finite element method. The influence of the contact model between the bones used, namely friction and bonding, on the results of the finite element analysis was studied before further research could be carried out. The load given is considered equivalent to the average body weight of the Indonesian population, which is around 63 kg. The material employed is AISI 316. Parameters for friction and bonded models used refer to previous researchers. The results of the analysis show significant differences in the distribution and magnitude of stress on the fixation plate due to the use of different contact models.

“…Ghany et al [30] estimated that in Egypt, the groundwater sector will experience a rapid decline in levels due to the decrease in water recharge in the renewable aquifers (Nile Valley and Delta aquifers). This decline is expected as a result of climate change and the construction of the GERD reservoir.…”

Over the past two decades, rapid climate change has severely impacted people’s lives globally, affecting their safety and sustainability. Water, a vital human resource, has been severely affected, with drought and high temperatures leading to desertification, the drying up of rivers and lakes, spontaneous fires in forests, and massive floods and torrents due to melting ice and rising sea and ocean surface water levels. The expected impacts of climate change on the Nile, Egypt’s primary water source, are significant. These impacts can vary across regions, depending on factors like local climate, socio-economic dynamics, topography, and environmental nature. Upper Egypt, characterized by arid and semi-arid regions, faces water scarcity and socio-economic development challenges. Climate change exacerbates these issues, posing significant threats to the region’s ecological sustainability and socio-economic development. Therefore, it is crucial to address these impacts to ensure the Nile’s continued vitality and sustainability. The study aims to analyze the climate change data over the past few decades, analyze its characteristics, and model its effects on Upper Egypt’s water sources. The study expected a big decrease in the water resources of the Nile. While what is currently occurring in terms of fluctuating rainfall rates between scarcity and severity contradicts the results of those studies, that is the best evidence of the need for further research and studies to obtain more reliable and consistent results with the reality that it may help decision-makers to develop scenarios to manage climate change effectively, preventing or reducing negative effects, and finding suitable alternatives. Studies predict a 10% decrease in Nile revenue at Aswan High Dam Lake by 2095, with some predicting a 30% increase. This lack of credibility underscores the need for more comprehensive studies.
