The key issues in designing ballastless track for high-speed railway bridges are to reduce maintenance and improve track smoothness by understanding fatigue damage characteristics.This paper is based on the principle of bridge-rail interaction and train-track-bridge coupling dynamics, the refined simulation model of bridge-CRTS I Bi-block ballastle
DNA is considered as a useful building bio-material, and it serves as an efficient template to align functionalized nanomaterials.Riboflavin (RF)-doped synthetic double-crossover DNA (DX-DNA) lattices and natural salmon DNA (SDNA) thin films were constructed using substrate-assisted growth and drop-casting methods, respectively, and their topologic
In the present paper, results of the research on application of residual THYRO SENSE fine-grained, carbon-bearing materials as coke substitutes in the shaft process of copper matter smelting are discussed.The addition was introduced into the charge as a component of concentrate-made briquettes, then, its effects on properties of the obtained brique
Interpersonal communication has been severely affected during the COVID-19 pandemic.Protective measures, such as social distancing and face masks, are essential to mitigate efforts against the virus, but pose challenges on Gift Cards daily face-to-face communication.Face masks, particularly, muffle sounds and cover facial expressions that ease comp
