The tail-sitter Vertical Takeoff and Landing (VTOL) Unmanned Aerial Vehicle(UAV), flying in a fixed-wing model, overcomes many shortcomings of traditional fixed-wing UAVs, and inherits the advantage of high overall efficiency, which means it has great development potential and very Pet Edible broad application prospects.The attitude of tail-sitter
Food security will be a substantial issue in the near future due to the expeditiously growing global population.The current trend in the agriculture industry entails the extravagant use of synthesized pesticides and fertilizers, making sustainability a difficult challenge.Land degradation, lower production, and vulnerability to both abiotic and bio
Biofuels from algae are highly interesting as renewable energy sources to replace, at least partially, fossil fuels, but great research efforts are still needed to optimize growth parameters to develop competitive large-scale cultivation systems.One factor with a seminal influence Pates on productivity is light availability.Light energy fully suppo
