“…provide safe and detailed mapping of geological structures, especially in inaccessible and hazardous areas, with the obtaining of a 3D image of the quarry edge from two parts: a 3D point cloud and a photograph. This combined image is then used for subsequent interpretation of geological and potentially hazardous structures in the quarry edge [6][7][8][9][10][11][12].…”

The article discusses the fundamental conceptual positions underlying the study of the significant impact of humanity on the lithosphere, which is approaching and may exceed its limits. It is noted that most surface layers of the Earth's crust are non-renewable, and the majority of chemical elements have found practical applications, yet only about oneseventh of the extracted minerals are used in the production of final products. One of the main challenges in developing open-pit mines is maintaining the stability of the pit walls. As the depth of the pit increases, this issue becomes increasingly critical. The article emphasizes the importance of enhanced study of the fundamentals of managing rock masses in mining operations and the practical application of this knowledge, as it significantly contributes to solving problems and examples related to assessing the stability of slope walls and pit benches.

Da mesma forma, a microCT é uma ferramenta importante na análise da dinâmica do ataque de fungos xilófagos na madeira associado com a avaliação das suas características anatômicas (Van den Bulcke et al, 2009b).…”

RESUMOA microtomografia computadorizada de raios X (microCT) é uma das mais avançadas técnicas de análise não destrutiva e possibilita a reconstrução da estrutura anatômica da madeira e de seus produtos. O trabalho aplicou a microCT na análise da anatomia da madeira de Amburana cearensis e de Pinus sp. A microCT possibilitou a obtenção de imagens da estrutura macro e microscópica da madeira das duas espécies, permitindo a sua caracterização, descrição e comparação com a da literatura. As vantagens da microCT, em relação à confecção de lâminas histológicas, mantendo a integridade das amostras de madeira, painéis, carvão, papéis, etc. são discutidas.Palavras-chave: microtomografia de raios X, Amburana cearensis, Pinus sp. X-ray Microtomography to Anatomical Characterization of Softwood and HardwoodABSTRACT X-ray computed microtomography (microCT) is one of the most advanced non-destructive techniques enabling the reconstruction of wood anatomical structure and its products. This work applied the microCT to the analysis of wood anatomy of Amburana cearensis and Pinus sp. Through microCT it was possible to obtain images of the macro and microscopic wood structure of the two species, followed by the characterization, description and comparison to the literature. The advantages of microCT are discussed in relation to the preparation of histological slides, providing the integrity of wood, panels, charcoal, paper samples, etc.

“…Moisture is a research focus in the field of wood materials, and a complete knowledge system of the relationship between matter and water has been formed (Skaar 1988;Wiberg 1995;Eriksson et al 2007;Wu and Peng 2007;Siau 2012;Huang et al 2017;Kang et al 2019). Moisture changes in the drying process are an important factor that affect the drying quality of round bamboo.…”

Characterized by its light weight, high strength, and good flexibility, round bamboo is a natural functional biomaterial with a multi-level structure. Cracking is a key factor hindering its wider application. Moisture changes cause cracking when the round bamboo is dried. Therefore, studying moisture variations in the drying process of round bamboo can effectively reduce or solve the cracking problem. In this study, microwave drying with computer tomography (CT) imaging technology was used to understand the distribution and migration of moisture in round bamboo in the course of drying. The results indicated that water content has a significant correlation with the CT value, which can be used to achieve rapid determination of water content. The radial water content of samples gradually decreased from bamboo green (outer) to bamboo yellow (inner). The axial water content was high in the middle and low on both ends. As the water content decreased, the axial moisture distribution was consistent. The internode moisture mainly moved from the junction of bamboo yellow and bamboo partition, entered the adjacent cavity, and then gradually moved outward. Thus, the microwave drying method can effectively achieve industrial drying of round bamboo and prevent cracking.
