Root growth and soil nitrogen depletion by onion, lettuce, early cabbage and carrot [PDF]
, 2001 Experiments examining root growth, the utilization of N and the effect of green manures were carried out on four vegetable crops. Large differences were observed both in rooting depth penetration rates, and in final rooting depth and distribution.

Role of Air in Granular Jet Formation [PDF]
, 2007 A steel ball impacting on a bed of very loose, fine sand results in a surprisingly vigorous jet which shoots up from the surface of the sand [D. Lohse et al., Phys. Rev. Lett. 93, 198003 (2004)].

Penetration Rates of Formaldehyde [PDF]
Microscopy Today, 2002 Abstract Formaldehyde is one of the most rapidly penetrating fixatives used. Unfortunately, it is one of the slowest to fix tissue. This paradox was finally explained by Burnett in 1982. An fine description of the properties of formaldehyde may be found in John Kiernan's book.

Prediction of penetration Rate and cost with Artificial Neural Network for Alhafaya Oil Field
Iraqi Journal of Chemical and Petroleum Engineering, 2018 Prediction of penetration rate (ROP) is important process in optimization of drilling due to its crucial role in lowering drilling operation costs. This process has complex nature due to too many interrelated factors that affected the rate of penetration,
