Performance evolution and influencing factors of hold-down springs in nuclear reactor internals under high-temperature cyclic loading conditions

As a critical component in reactor internals, the performance of hold-down springs directly affects operational safety. However, most existing studies are conducted under room-temperature conditions, which is difficult to reflect the performance evolution law in actual high tempe...

GNSS monitoring and stability evolution mechanism of the S-J1 deformation body in the lower reaches of the Jinsha River

Catastrophic landslides triggered by reservoir impoundment represent one of the most destructive geohazards in the field of hydropower engineering, posing significant threats to human lives, property, and the long-term operational safety of critical infrastructure. A large hydrop...

How has Shanghai built a sustainable municipal solid waste management system through 30 years of socio-ecological practice?

Municipal waste management, widely recognized as a complex problem involving environmental, social, economic, and governance issues, has long received extensive attention from governments, academia, and the public. Since the late twentieth century, Shanghai has undergone a three-...

The efficacy of stem cell therapy: cells or their microenvironment?

The therapeutic outcomes of stem cell therapy are determined not solely by cellular potency alone, but also by the receptiveness of the host microenvironment. Despite continuous progress in stem cell quality control and functional optimization technologies, inconsistent outcomes...

Electrical conductivity models for bubble-bearing marine fine-grained sediments

Abstract Large sediment-displacing bubbles are widespread in seafloors and typically found in shallow and fine-grained sediments. These bubbles have significant environmental and engineering impacts. Acoustic methods are the most widely used geophysical investigation method for b...
