A recent study conducted by researchers at the University of Technology-Iraq explores the design and manufacturing of custom 3D printed bone implants for medical surgery. The study investigates the use of additive manufacturing, specifically 3D printing, to create customized implants that meet surgical requirements. The research utilizes CT scans to capture implant shape data, which is then processed using a systematic approach to generate the final design of the implants. The study concludes that this approach enables the creation of complex implant geometries that would otherwise be challenging to manufacture. The technique shows promise for the future of medical surgery and orthopedics, provided that biocompatible materials are used. [Extracted from the article]

Researchers from Universite de Carthage in Tunisia have conducted a study on the reliability of dialysis machines in a stochastic environment. The study focused on the effect of uncertainties in the Weibull parameters on the reliability of the machines. The researchers estimated the shape and scale parameters through analytical and graphical methods based on the failure history of the devices. The study also examined the random failure rate, reliability, and the potential for an efficient preventive maintenance program. This research provides valuable insights into improving the reliability of dialysis machines. [Extracted from the article]

Researchers from the University of Technology-Iraq have published a study on the use of composite bone plates in healing long-bone fractures. The study explores the use of bio-composites made from Ultra High Molecular Polyethylene (UHMWPE) reinforced with Nano Hydroxyapatite (n-HA) and Nano Titanium Dioxide (n-TiO2) particles, as well as carbon and Kevlar fibers. The researchers conducted compression tests, hardness tests, and density measurements on the specimens and found that UHMWPE+4.5%n-HA+CF hybrid biocomposite had the highest compressive strength and hardness properties. The study suggests that bio-composites with different fiber reinforcements can be used to create internal fixation devices with improved performance. [Extracted from the article]

Researchers at the University of Baghdad have conducted a study on the effect of the Pierce parameter on the output of the free electron laser system. The Pierce parameter is an important factor in measuring the performance quality of the laser system. The simulation results showed that the values of the Pierce parameter varied depending on the wavelength of the laser beam, with higher values leading to increased efficiency of the laser system. The study also found a direct relationship between the Pierce parameter and the small signal gain per unit length. For more information, readers can refer to the Engineering and Technology Journal article by Thair Al-Aish and Hanady Kamil. [Extracted from the article]
