Tourism is a major economic activity with significant social, political and environmental repercussions that affect people and places in virtually every corner of the contemporary world. This study focuses on tourism ...

This study provides a review of methods used for stability monitoring in two different fields, electrical power systems and vibration analysis, with the aim of increasing awareness of and highlighting opportunities for ...

For a quantum system governed by a non-Hermitian Hamiltonian, we studied the problem of obtaining an optimum Hamiltonian that generates nonunitary transformations of a given initial state into a certain final state in the ...

In this paper an artificial neural network is developed to model a new depollution process that uses sequential cultures of anaerobic bacteria and yeasts to efficiently remove both carbon and nitrogen from wastewaters. A ...

Objective: The aim of the study was to investigate the blood pressure variability during 24 h by using ambulatory blood pressure monitoring (ABPM) in a group of obese and non-obese female adolescents with breast development ...

Previous work has shown that the carotid body glomus cells can function as glucose sensors. The activation of these chemoreceptors, and of its afferent nucleus in the brainstem (solitary tract nucleus - STn), induces rapid ...

In this work, a mathematical model to describe the dynamics of a glucose fermentation process to produce ethanol is proposed. This process is carried out using immobilized yeast in a fluidized bed bioreactor. The model is ...
