NUMERICAL ANALYSIS OF FACTORS AFFECTING THE BURDEN SURFACE AND POROSITY DISTRIBUTION IN THE UPPER PART OF THE BLAST FURNACE

Numerical Analysis of Factors Affecting the Burden Surface and Porosity Distribution in the Upper Part of the Blast Furnace

A proper burden and porosity distribution of the bed in the upper shaft are important prerequisites for realizing a stable and efficient operation of the ironmaking blast furnace.The discrete element method was used to investigate the effects of the static friction coefficient corky lala between burden particles and shaft angle on the burden profil

Recurrent Nevus Phenomenon Developing within a Keloid

The recurrent nevus phenomenon represents the persistence of a nevus within a scar from a prior biopsy site, with the acquisition of clinical and histologic features frequently overlapping with those of melanoma, posing relevant diagnostic challenges.Similar features are recognized in nevi that have undergone recent or chronic trauma and in scleros

Ion Mobility-Mass Spectrometry-Based Measurements of Collision Cross Section Values for Metabolites and Related Databases

Metabolomics aims to systematically profile various small molecules (i.e., metabolites and lipids) in biological samples.Compared with genomics, transcriptomics and proteomics, metabolomics locates in the downstream of omics technologies, which links genotype with phenotype.Metabolomics is an important part of system biology.It has been widely appl
