Reinforced concrete (RC) columns, being axial-bearing components in buildings, are susceptible to damage and failure when subjected to blast loading. The failure of these columns can trigger a progressive collapse in targeted buildings. The primary objec...

Although mangrove forests occupy only 0.5% of the global coastal area, they account for 10?15% of coastal organic carbon (OC) storage, and 49?98% of OC is stored in sediments. The biogeochemistry of iron minerals and OC in marine sediments is closely rel...

An asteroid impact can potentially destroy life on this planet. Therefore, asteroids should be prevented from impacting the Earth to impede severe disasters. Nuclear explosions are currently the only option to prevent an incoming asteroid impact when the...
