Opis:: Through taking the cold rolling process as the research object, the three-dimensional finite element model of the strip rolling process is established by using ANSYS/LS-DYNA software. The actual rolling product data has strong consistency with the finite element simulation results. The rolling process is dynamically simulated, and the distribution curves of important rolling parameters such as equivalent stress, control efficiency coefficient, transverse rolling pressure, lateral thickness and work roll deflection is obtained. Based on summarizing the influence of rolling parameters on rolling deformation, the research results of this paper can play an important role in the actual rolling process control. The research results have certain guiding significance for the development and optimization of the rolling control system.

Opis:: Objective: The current study aims to investigate, which of the factors are directly and indirectly associated with disordered eating in a non-clinical population of university students in Slovakia. Methods: 302 university students (52.3% female, M age=21) filled in a questionnaire assessing the perceived pressure to be thin, the internalization of appearance ideals, disordered eating, satisfaction of basic psychological needs and the regulation of exercise. The hypothesized model was tested with a parallel multiple mediation analysis using PROCESS macro. Results: The pressure to be thin from partner, the internalization of appearance ideals and the controlled regulation of exercise were directly associated with disordered eating. The pressure to be thin from media was indirectly associated with disordered eating through the internalization of appearance ideals. The pressure to be thin from partner and from family as well as satisfaction of the need for competence were indirectly associated with disordered eating through the controlled regulation of exercise. Conclusions: The results of the current study support the focus of the existing eating disorder interventions at decreasing the internalization of sociocultural appearance ideals. The results suggest the usefulness of incorporating the promotion of autonomous regulation of behaviour, especially with regard to exercising, within the prevention and intervention field.
