Effect of Rock Joint on Boreability of TBM at Northern Section of Kerman Water Conveyance Tunnel [PDF]
International Journal of Mining and Geo-Engineering, 2021 Nowadays, Tunnel Boring Machines (TBM) are widely used around the world on account of their high rate of excavation, little impact on the surrounding rock and their high safety standards.

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)].

Penetrance rate estimation in autosomal dominant conditions [PDF]
Genetics and Molecular Biology, 2012 Accurate estimates of the penetrance rate of autosomal dominant conditions are important, among other issues, for optimizing recurrence risks in genetic counseling. The present work on penetrance rate estimation from pedigree data considers the following situations: 1) estimation of the penetrance rate K (brief review of the method); 2) construction of

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.
