Hace 1 día · Double-heading, the practice of using two steam locomotives to pull a single train, was a common sight on railroads during the age of steam. This method was employed to manage heavy loads, navigate steep gradients, or improve reliability and efficiency. Although double-heading may seem like a straightforward practice, it involved meticulous ...
Hace 16 horas · Basing on this coupling interaction and characteristics of MHBS, environmental factors (i.e., temperature, pore water pressure and salinity) calculated by T + H and mechanical property (porosity) calculated by PFC are chosen here as exchange data for coupling simulation here. The detailed architecture is shown in Fig. 2.

Hace 16 horas · Summary. The understanding of past changes in climate and ocean circulation is to a large extent based on information from marine sediments. Marine deposits contain a variety of microfossils, which archive (paleo)-environmental information, both in their floral and faunal assemblages and in their stable isotope and trace element compositions.
