Crushing mathematical modeling using particles population balance method is a fundamental tool for process analysis, optimization and design. This paper deals with the evaluation of the fracture events and process in cone and rolls crushers. For that proposes, is taken as reference Whiten (1972) structural model modifying fragmentation distribution function. This function was replaced by Austin and Luckie (1972) expression. For model development, was created an algorithm using Matlab 13a like determining resource of fractures parameters. Model estimated error for evaluated crushers established the viability of its use for modelling and simulation, particularly for rolls crushers that even before were simulated by simple fragmentation models. Classification and fragmentation distribution functions obtained, describe the events and process fracture essentials that take place in both crushers. [ABSTRACT FROM AUTHOR]

Professionals from Medical Sciences need to analyze and interpret biomedical phenomena modeled by elementary functions as well as the information processing and interpretation of optimization processes through the working methods of Superior Mathematics, leading to the need of establishing the essential traits of the systematization of mathematical contents integrated into biomedical contents within the curricular diversity in the major of Medicine, from the academic, labor and research components. The article aims at showing how to benefit from the teaching - learning process of the biomedical subjects as a basis of the model of systematization of mathematical contents, integrated into biomedical contents, in the major of Medicine and its methodology. Finally, in the article, the use of mathematical contents in the description of behavior of the dengue, starting july 1st till september 30 2015 in Holguín. [ABSTRACT FROM AUTHOR]
