To improve the productivity and efficient of modern large-scale open-cut mines, a number of technologies are developed and trialed, including new blasting equipment, larger blasting holes, high benches, air spacing, and short-delay blasting within holes.However, the relative blasting parameters need field calibration and further investigation of th
RADIX (Rapid Access Drilling and Ice eXtraction) Capsule Support Holder is a prospecting drilling system that has been designed, realized and tested on polar ice sheets.The goal of RADIX is to provide rapid, deep access for sampling of ice and downhole physical measurements that inform about ice sheet age and history and the integrity of layering.A
Time-dependent heat transfer in a dense gas between two parallel plates, which is initiated by an abrupt change in temperature of one plate, is numerically investigated on the basis of the Enskog equation under the diffuse reflection boundary condition.Numerical computation is carried out by a finite-difference scheme combined with the Fourier Inpu
Gelochelidon nilotica and Sterna hirundo are two sympatric breeding species.The mitogenomes of G.nilotica and S.hirundo are 16,748 bp and 16,707 bp in size.Both two mitogenomes reveal the same gene order and genomic organization to that of typical avian mtDNA.The first conserved blocks Hayward C-Spa XI Parts with a interrupted poly-C are present in
