AI Article Synopsis

  • Gamma-ray computed tomography (CT) was used to analyze soil clod samples and study their porosity (ϕ).
  • Samples collected from the soil surface varied in volume from 50 to 100 cm³ and were imaged in 2D with high resolution.
  • The study revealed insights into the internal structure of soil clods that traditional methods could not provide, highlighting the significant variability in soil quality.

Article Abstract

Gamma-ray computed tomography (CT) was employed to study the soil quality of clod samples used to investigate porosity (ϕ). Samples with volumes varying from 50 to 100cm(3) were collected from the soil surface. 2D CT images were obtained with millimetric resolution. Porosity distribution analyses were carried out to infer the soil clod structure. Results obtained provided a new insight on the variability of internal clod structure due to the large amount of data analyzed, information that is not provided by traditional methods used in physics applied to soil.

Self-organization under out-of-equilibrium conditions is ubiquitous in natural systems for the generation of hierarchical solid-state patterns of complex structures with intricate properties. Efforts in applying this strategy to synthetic materials that mimic biological function have resulted in remarkable demonstrations of programmable self-healing and adaptive materials. However, the extension of these efforts to multifunctional stimuli-responsive solid-state materials across defined spatial distributions remains an unrealized technological opportunity.

In this work, taking wells LD1, LD2, and LY2 in the Laifeng-Xianfeng area as the research target, through core description, intensive core sampling, experimental analysis, imaging logging and other methods, the characteristics of graptolite zone development, organic carbon content, mineral composition, shale reservoir properties and the gas-bearing properties of the Wufeng-Longmaxi Formation shale are systematically analyzed. The main factors affecting the gas-bearing capacity of the Wufeng-Longmaxi Formation shale are extensively evaluated. The results reveal the following: ① The Wufeng-Longmaxi Formation shale, which was deposited in a deep-water shelf environment, has a large thickness (50-60 m) and a stable distribution.

Three-dimensional printed Ti-6Al-4V hemipelvic prosthesis has become a current popular method for pelvic defect reconstruction. This paper presents a novel biomimetic hemipelvic prosthesis design that utilises patient-specific anatomical data in conjunction with the Voronoi diagram algorithm. Unlike traditional design methods that rely on fixed, homogeneous unit cell, the Voronoi diagram enables to create imitation of trabecular structure (ITS).

Faculty of Chemical & Petroleum Engineering, University of Tabriz, Tabriz, Iran. Electronic address:

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.
