Influence of Recycled Aggregate on Shear Behavior of Steel Fibrous SCC [PDF]

, 2018
Of all the different kinds of failures in concrete, shear failure is a sudden and brittle and occurs abruptly without any prior warning. To avoid these types of failures in concrete, beams are traditionally reinforced with stirrups at closer spacing ...

Superannuation Reimagined: Moving Beyond the Origins to an Indigenous Focus

Australian Journal of Social Issues, EarlyView.
ABSTRACT Retirement income systems, such as superannuation, are meant to be non‐discriminatory and consider disadvantage faced by members of society. There are significant differences between the life expectancies of Indigenous and non‐Indigenous peoples. The gap in life expectancies is not considered when determining when Indigenous peoples can retire.

Unlocking the Continuous Flow Asymmetric Hydrogenation of Olefins Through the Development of a Non‐Deactivating Immobilized Iridium Catalyst

Angewandte Chemie, EarlyView.
We have developed stable, robust, and reusable heterogeneous metal catalysts for an efficient continuous flow asymmetric hydrogenation (AH) of a variety of olefins, far beyond the typical benchmark AH. The products are produced continuously over long periods of time with high catalytic performance (up to 99% ee).
