Lightweight Clay Aggregate (LWCA) is a kind of highly porous granular particle which often used as lightweight backfilling geomaterials. However, the easy breakage LWCA plays negative role in its geotechnical application. This study focuses on internal structure and compressive behavior single using experiments numerical simulations. The uniaxial strength loading stiffness attributed to special...

We have developed a process to incorporate an integral membrane protein, Photosystem I (PSI), into an organic thin film at an electrode surface and thereby insulate the protein complex on the surface while mimicking its natural environment. The PSI complex, which is primarily more hydrophobic on the exterior than interior, is hydrophobically confined in vivo within the thylakoid membrane. To mi...

INTRODUCTION Beijing subway line 14 includes four stations and approximately 2.8 km of tunnels between the Dongfengbeiqiao and Jingshunlu areas of the city. Due to the surface and underground space limitations of this section, a double-track running tunnel instead of two single-track running tunnels was adopted to connect the two stations. The double-track tunnels were excavated by a 10.22 m di...
