Enabling a More Externally Focused and Operational PLA – 2020 PLA Conference Papers

Although the People’s Liberation Army is not yet a global expeditionary force on par with the US military, the former has nevertheless significantly expanded its ability to operate abroad. Through enhanced technological capabilities, robust relationships with foreign militaries, increased access to overseas military bases and dual-use facilities, and the implementation of major structural reforms, the People’s Liberation Army has built a more integrated joint force capable of conducting a wider and more complex array of missions. This volume advances the understanding of the People’s Liberation Army’s capability to conduct overseas missions by examining China’s military relations with Europe, Africa, and Latin America; the country’s military activities in the Indian Ocean, polar regions, and Pacific Island countries; and the emerging roles of the People’s Liberation Army Rocket Force and the Joint Logistic Support Force. This volume finds the People’s Liberation Army is engaged in a wide range of activities throughout the world, including port calls, joint exercises, seminars, and personnel exchanges. China sells weapons to some parts of the world and seeks to acquire military and dual-use technology from others. In addition, the People’s Liberation Army seeks to increase its capability to operate in parts of the world, such as the Indian Ocean, Pacific Island countries, and polar regions, where the organization has only had a minimal presence in the past.https://press.armywarcollege.edu/monographs/1947/thumbnail.jp

Antimicrobial particulate silver coatings on stainless steel implants for fracture management

We have used particulate silver coating on stainless steel to prevent in vivo bacterial infection. Stainless steel is commonly used as an implant material for fracture management. The antimicrobial use of silver has been well documented and studied, therefore the novelty of this research is the use of a particulate coating as well as facing the real world challenges of a fracture repair implant. The variable parameters for applying the coating were time of deposition, silver solution concentration, voltage applied, heat treatment temperature between 400 to 500 °C and time. The resultant coating is shown to be non-toxic to human osteoblasts using an MTT assay for proliferation and SEM images for morphology. In vitro silver release studies of various treatments were done using simulated body fluid. The bactericidal effects were tested by challenging the coatings with P. aeruginosa in a bioreactor and compared against uncoated stainless steel. A 13-fold reduction in bacteria was observed at 24 hours and proved to be statistically significant
