Equal-thickness screening is a critical part of mineral processing; recently, the multistage variable-inclination equal-thickness screen (MSVIETS) has been utilized in the mining industry across the world. In this work, a model of the collision mechanics between particles and the multistage variable-inclination screen surface was established. The maximum collision force ( ) was found to be closely related to amplitude, frequency, screen surface inclination, and number of stages.

In this study, waste printed circuit boards were treated by alkaline immersion to enhance the flotation efficiency. Firstly, the SEM-EDS analysis of the crushed products shown that metal and nonmetal were completely liberated in the -0.

By comparing the applicability of different constitutive models, the reasonable parameters of the proposed Money-Revlon constitutive model were determined by rubber compression test and least square method. Considering the structural characteristics and complex constraints of the isolator, a step-by-step analysis method is described, based on the rigid-flexible coupling theory and the contact cutting algorithm.

- - A study investigates the prevalence and risk factors of nontraumatic osteonecrosis of the femoral head (NONFH) in China, revealing that about 8.12 million individuals aged 15 and over are affected, with a higher prevalence in males and residents of northern regions.
- - The research involved over 30,000 participants, who underwent various tests and questionnaires to explore the link between NONFH and factors like cholesterol levels, demographic elements, and lifestyle choices.
- - Key risk factors identified include high triglyceride and cholesterol levels, male gender, urban living, family history, heavy smoking, alcohol abuse, glucocorticoid use, and obesity, emphasizing the need for public health policies to address this issue.
