The effects of gravity on rock fractures caused by PDC bits [PDF]
Scientific ReportsTo understand the crack propagation and chip formation mechanism caused by a PDC bit for various gravity values, a numerical study using particle flow code in 2 dimensions (PFC 2D) is performed.

Local unitarity: cutting raised propagators and localising renormalisation
Journal of High Energy Physics, 2022 Abstract The Local Unitarity (LU) representation of differential cross-sections locally realises the cancellations of infrared singularities predicted by the Kinoshita-Lee-Nauenberg theorem. In this work we solve the two remaining challenges to enable practical higher-loop computations within the LU formalism.

PROPAGATION OF PECAN BY STEM AND ROOT CUTTINGS [PDF]
HortScience, 1992 Certain key experiments on the clonal propagation of pecan by stem and root cuttings are described. Juvenile cuttings of pecan cv. `Stuart' produced more roots and a larger percentage of rooted cuttings than adult cuttings when treated with 1% solution of (IBA) in Feb. and Aug.

Effect of terms and conditions of cutting propagation on the rooting of coniferous trees [PDF]
E3S Web of Conferences, 2023 The Irkutsk region has large forests. They occupy 83% of the territory and amount to more than 11% of the total Russian forests. The active production growth has a negative impact on the environment.
