Measles, a highly contagious airborne disease, remains endemic in many developing countries with low vaccination basket coverage.In this paper, we present a deterministic mathematical compartmental model to analyze the dynamics of measles.We establish global stability conditions for both disease-free and endemic equilibria using the Lyapunov functi
The development of electronic technology has Nursing Pads accelerated in recent decades.Consequently, electronic wastes such as cathode ray tube (CRT) glass are accumulated, and hazardous wastes including heavy metals are generated.Simultaneously, natural resources are required to create concrete; however, they are already exhausted.Furthermore, he
To investigate the nutrient distribution characteristics and the eutrophication status of the main fishing ports in Hainan Province, this study analyzed the 2021 Nursery seawater quality indicators, including biochemical oxygen demand (BOD5), chemical oxygen demand (COD), chlorophyll a (Chl a), ammonia nitrogen (NH4-N), nitrite nitrogen (NO2-N), ni
Percutaneous replacement of the tricuspid valve with a bovine jugular venous valve (melody valve) was successfully undertaken in a 9-year-old boy.The patient had a previous history of Buffers bacterial endocarditis of the native tricuspid valve in infancy.Initially, a pericardial patch valve was created, followed by surgical replacement of the valv
