Beyond Accessibility: Evidence Centered Design For Learning (Ecdl) For Improving The Efficiency Of Instruction.
This paper illustrates how Evidence Centered Design (ECD) can be used to address the accessibility of learning-centered assessments, and how such efforts lay a critical foundation for improvements in other aspects of quality, particularly learning efficiency.

Equatorial Counter Electrojets and Polar Stratospheric Sudden Warmings – a Classical Example of High Latitude-Low Latitude Coupling?
It is observed that, the stratospheric temperature at ~30 km over Trivandrum shows a sudden cooling prior to the SSWs and the CEJs of maximum intensity which occurs around this time.

Petri Dish PCR: Laser-Heated Reactions in Nanoliter Droplet Arrays
We report high-speed real-time PCR performed on an unmodified disposable polystyrene Petri dish. The reaction cycle relies solely on an infrared laser for heating; no conventional heater is required.
