Erosion rate and previous extent of interior layered deposits on Mars revealed by obstructed landslides [PDF]
We describe interior layered deposits on Mars that have obstructed landslides before undergoing retreat by as much as 2 km. These landslides differ from typical Martian examples in that their toe height increases by as much as 500 m in a distinctive ...

The Influence of Radiation on Confinement Properties of Nuclear Waste Glasses
Self-irradiation can affect durability of glasses used to immobilize high-level nuclear waste (HLW). The stability of glasses can also be indirectly affected by the radiolytic changes in contact water leading to decrease in its pH although this is ...
