This comment analyses the results of the fixed-bed column modeling from the studies published by Gupta and Garg (2019), and Das et al. (2020), which are the last two papers on this topic published in this journal.

The questions, whether mathematical modelling can be learnt and what we know from empirical research, are highly relevant not only for the current research on modelling, but they are as well essential for curricular changes ...

Extraction-transformation-loading (ETL) processes play an important role in a data warehouse (DW) architecture because they are responsible of integrating data from heterogeneous data sources into the DW repository. ...

Abstract Despite the increasing body of evidences on the factors influencing leisure-time physical activity, our understanding of the mechanisms and interactions that lead to the formation and evolution of ...

Physical activity has been scientifically discussed as fundamental in the process of healthy ageing. Hence, this study aimed at determining the factors that influence older people to perform physical activities. The complete ...

This paper presents a brief discussion with regard to the fixed-bed modeling results of a recent paper by Li et al. published in this journal.

The need to relate the various architectural domains captured in partial descriptions of an enterprise is addressed in virtually all enterprise modeling approaches. One of these domains, namely that of organizational ...

The aim of this study is to analyze a mathematical modeling task developed by students in the sixth grade of primary education (11-12 years old) based on a model-eliciting activity with real statistical data about COVID-19, ...
