Study on pore structure and fractal characteristics of middle rank coal reservoir in Longtan Formation of Panguan syncline
Published 2025-06-01“…The results show that: there are mainly five types of microscopic pores in the middle rank coal of Longtan Formation in Panguan syncline; the pore morphology of the piezoelectric mercury curve is divided into three types; the seepage fractal dimensions are smaller than the diffusion fractal dimensions, and the comprehensive fractal dimensions mainly reflect the complexity of the diffusion pores; the seepage fractal dimensions are negatively correlated with the vitrinite reflectance, the ash, the mineral mass fraction, the porosity, the average pore size, the total pore volume, and the permeability, and positively correlated with the moisture; and the diffusion fractal dimensions are negatively correlated with the ash, the mineral mass fraction, the average pore size, and the total pore volume. …”

La sátira de costumbres como artefacto ideológico. En torno a un opúsculo de 1808
Published 2015-03-01“…The invasion of Spain by France in 1808 was followed by the diffusion of many pamphlets and press articles. Among this extensive literature, a brochure entitled Higiene política de la España is worth mentioning: it has not drawn much attention from the commentators probably because it is a literary composition of a poor quality, but it exemplifies in a tellingly manner the political methods that the conservatives used to resort to in order to foster a reading of patriotic resistance that would fit into their ideological frame of interpretation. …”

Analytical review of the wear resistance of CBN tools in face milling of hardened steels
Published 2024-12-01“…Adhesive wear happens due to the sticking of tool and workpiece materials, resulting in micro-welds and subsequent particle detachment. Diffusion wear is caused by high temperatures in the cutting zone, leading to atom diffusion between the tool and workpiece, changing the chemical composition and structure of the tool. …”
