Radiography is of importance in the diagnosis of atlantoaxial dislocation (AAD), and it is the basic imaging technique. However, it should not be the sole diagnostic modality, especially in complex or unclear cases. Conventional X-ray includes an open-mouth odontoid view and a cross-table lateral vi...

Food is essential for sustaining human life. While people love delicious food, they often neglect the care for it. One of the most commonly wasted foods is bread. There has not been much research on bread waste. Carbon emissions from bread are not less than those from meat products. Therefore, it is...

ABSTRACT Corrosion‐resistant reinforcements in coral aggregate concrete (CAC) do not adequately prevent matrix corrosion due to the high porosity of CAC. Here, the corrosion of CAC in marine environments was systematically reviewed, and methods to enhance its corrosion resistance were discussed. The...

Phosphorus (P) is a limiting nutrient element for crop. To obtain maximum crop yield, P fertilizer is often over-applied, which leads to accelerating exhaustion of phosphate resources and serious environmental problems. Reducing the application of P fertilizer and enhancing the P utilization efficie...

In this paper, a wideband circularly polarized folded reflectarray antenna (CPFRA) based on a transmissive linear-to-circular polarization converter is proposed. The CPFRA consists of a primary reflector and a sub-reflector. To achieve broadband performance, a metasurface-based RA element on the pri...
