Critical-Angle Differential Refractometry of Lossy Media: A Theoretical Study and Practical Design Issues

Instruments, 2019
At a critical angle of incidence, Fresnel reflectance at an interface between a fronttransparent and a rear lossy medium exhibits sensitive dependencies on the complex refractiveindex of the latter.

Comparison of the effects of high and low milk-replacer feeding regimens on health and growth of crossbred dairy heifers [PDF]

, 2019
Context: Pre-weaning growth in dairy heifers is highly dependent on the amount of milk fed. Both milk replacer (MR) and associated labour are costly, encouraging restricted milk rations and once-a-day feeding.
