The diaphyses of the tubular bones of seven men aged 40-60 years without the bone pathology were studied. Porosity characteristics of the compact substance were measured in the tibia and the humerus bones by the method of centrifugal porometry. This method is based on the filling of the objects studied with the wetting fluid and sequential removal of it by the centrifugation at increasing values of the centrifugal acceleration; as a result, the values of the radii of the pores and the respective distribution function of the pore volume could be obtained. The individual features of the bone porosity in different persons were detected, as well as the similarity of porosity characteristics of the bones belonging to one person. Porosity individual features are demonstrated in the form of the distribution curve of pore size and the quantitative distribution of porosity volume according to the pore radii. These features allow to confidently detect the belonging of bones to one person.

Coal gangue (CG) is an industrial solid waste produced by coal mining and separation that is considered to have a significant effect on the soil or water environment when exposed to the air, exacerbating ecological pollution. The comprehensive utilization of CG has always been a difficult problem due to the complex mineralogical characteristics. Producing concrete aggregates with CG is an effective strategy for utilising CG resources synthetically.

Background And Objectives: The liver, a vital metabolic organ, is always susceptible to various diseases that ultimately lead to fibrosis, cirrhosis, acute liver failure, chronic liver failure, and even cancer. Optimal and specific medicine delivery in various diseases, hepatectomy, shunt placement, and other surgical interventions to reduce liver damage, transplantation, optimal preservation, and revival of the donated organ all rely on a complete understanding of perfusion and mass transfer in the liver. This study aims to simulate the computational fluid dynamics of perfusion and the temporal-spatial distribution of a medicine in a healthy liver to evaluate the hemodynamic characteristics of flow and medicine transport with the purpose of more effective liver treatment.

Clarifying the pore-throat size and pore size distribution of tight sandstone reservoirs, quantitatively characterizing the heterogeneity of pore-throat structures, is crucial for evaluating reservoir effectiveness and predicting productivity. Through a series of rock physics experiments including gas measurement of porosity and permeability, casting thin sections, scanning electron microscopy, and high-pressure mercury injection, the quality of reservoir properties and microscopic pore-throat structure characteristics were systematically studied. Combined with fractal geometry theory, the effects of different pore throat types, geometric shapes and scale sizes on the fractal characteristics and heterogeneity of sandstone pore throat structure are clarified.

Crown ether is widely used in water purification because of its ring structure and good selective adsorption of specific heavy metals. However, its high cost and difficulty in recycling limit the purification of heavy metals in water. The anisotropic [2,4]-dibenzo-18-crown-6-modified bamboo pulp aerogel (DB18C6/PA) is successfully synthesized by microwave irradiation and directional freezing technology.
