Small modular reactor (SMR) refers to a new generation of reactors with a unit power output of less than 300 MW.These reactors utilize innovative technologies for modular design and rapid on-site assembly.The assurance of structural seismic safety becomes a crucial prerequisite for the commercial application of SMR.Traditional seismic resistance th
The cost of reproduction hypothesis suggests that current reproduction has Refrigerators:Reach-In Refrigerators inherent tradeoffs with future reproduction.These tradeoffs can be both in the form of energy allocated to current offspring as opposed to somatic maintenance and future reproduction (allocation costs), or as an increase in mortality as a
To study the dynamic characteristics and microstructure of nano-CaCO3 remolded soft clay under cyclic loading, GDS dynamic triaxial and NMR tests were conducted to analyze its dynamic stress-strain, dynamic elastic modulus, damping ratio, and micro pore changes.The results show that as the content of nano-CaCO3 increases and Velcro rollers the conf
