Herein, we develop and assess a low-cost droplet simulation model using easily accessible materials, open-source software, and a smartphone-based cobalt blue light. Methods. The simulation model was developed using commercial-grade materials and fluorescein dye. A clear face shield was assessed ten times following a simulated cough using fluorescein dye. A conventional ultraviolet Woods lamp was compared to a smartphone-based cobalt blue light to detect fluorescein illumination. Results. The simulation platform and smartphone-based cobalt blue light cost $20.18. A Wilcoxon signed rank test revealed that the median droplet area of fluorescence under the UV Wood’s lamp was not significantly different than that of the smartphone-based cobalt blue light (2.89 vs 2.94, P = .386). Conclusions. This simulation model is inexpensive and easily reproducible. The smartphone application may be a convenient alter...

Therefore, the European Bank for Reconstruction and Development aims to provide support to the economy and households in the Republic of North Macedonia through loans and grants to increase the share of renewable energy sources, especially solar energy, reduce dependence on electricity imports, as well as reducing coal energy production. The Energy Strategy of the Republic of North Macedonia until 2040 defines the long-term goals for the development of individual energy activities in order to ensure security in the supply of different types of energy, while providing conditions and ways for environmental protection and measures for realization of protection. The strategy relies on green growth and offers solutions to tackle climate change, especially in the green scenario. The green scenario envisages achieving the share of renewable energy sources up to 44% in 2040 in the total final energy consumption. The role of the European Bank for Reconstruction and Development in the promotion of renewable energy sources is indisputable, as well as achieving the goals of the Energy Strategy and the green scenario, and the ultimate goal is nature protection and greater energy efficiency.
