‘Turnaround’ of Indian Railways: Increasing the Axle Loading [PDF]

Vikalpa: The Journal for Decision Makers, 2008
Axle loading had contributed significantly to the ‘turnaround’ of the Indian Railways (IR) in the two years 2004-06. As the Minister of Railways (MR) stated, “A one ton extra loading per wagon implied additional revenue of Rs 500 crore per annum for IR.” The axle loading initiative was a significant step by IR, though sustainability was a concern.

Impact of Threading State on the Mechanics of γ‐Cyclodextrin–Pyrene Gels

Angewandte Chemie International Edition, EarlyView.
Tuning the threading state of discrete γ‐cyclodextrin (γ‐CD)–pyrene pseudorotaxane crosslinkers controls gel topology and ring mobility. The resulting doubly threaded slide‐ring networks exhibit solvent‐switchable dissipative dynamics, high extensibility, rate‐dependent mechanics, and low hysteresis, revealing how crosslink topology governs macroscopic
