The COVID-19 outbreak has generated, in addition to the dramatic sanitary consequences, severe psychological repercussions for the populations affected by the pandemic. Simultaneously, these consequences can have related effects on the spread of the virus. Pandemic fatigue occurs when stress rises beyond a threshold, leading a person to feel demoti...

In this work we report for the first time a mathematical approach to model the behaviour of a single oleosome (oil body) within a seed cellular environment. To describe the behaviour of the oleosome membrane, we adopted a dynamical continuum model based on the principle of the virtual work where the intrinsic energy of the lipid membrane is assumed...
Article
Mathematical models for the growth of tumours in the presence of stem cells (CSCs) and differentiated tumour cells (CCs) are presented and discussed. The CSCs are assumed to be immortal and multipotent, i.e. capable of generating several possible lineages of CCs that may undergo ageing and apoptosis. Each CC is characterised by two indexes, related...

In this paper, we discuss the assumptions, the balances, and the constitutive relationships in order to provide a set of tools for the mathematical modeling of a geothermal system. In particular, we present a model for pressure and saturation supposing that: 1) the geothermal fluid flows in a porous medium, 2) it is composed of pure water, 3) the s...

This work consists in the presentation of a computational modelling approach to study normal and pathological behavior of red blood cells in slow transient processes that can not be accompanied by pure particle methods (which require very small time steps). The basic model, inspired by the best models currently available, considers the cytoskeleton...
Article
The paper presents a conceptual mathematical model for Alzheimer’s disease (AD). According to the so-called amyloid cascade hypothesis, we assume that the progression of AD is associated with the presence of soluble toxic oligomers of beta-amyloid. Monomers of this protein are produced normally throughout life, but a change in the metabolism may in...

Although two-dimensional (2D) parabolic integro-differential equations (PIDEs) arise in many physical contexts, there is no generally available software that is able to solve them numerically. To remedy this situation, in this article, we provide a compact implementation for solving 2D PIDEs using the finite element method (FEM) on unstructured gri...

A perda de peças metálicas por ação da corrosão tem sido objeto de estudo de engenheiros e metalúrgicos que procuram constantemente aperfeiçoar e desenvolver novos métodos de proteção que apresentem resistência à corrosão, uma maneira como isso pode ser alcançado é através do processo laser cladding. Nesse processo é depositado um metal de adição d...

An experience can be defined as the "the result of encountering, undergoing, or living through situations" and "triggered stimulations to the senses, the heart, and the mind". Senses play a central role in our perception of the surrounding world and in the experience process. According to this, the study of sensory dimension of tourist experiences...

— The evolution of a geothermal system is studied. A mathematical model is proposed and the corresponding free boundary problem is formulated in a one-dimensional geometry. A situation corresponding to the geothermal field in Larderello, Tuscany (Italy) is considered, showing that the problem has two characteristic time scales, related to the motio...

Many important microfluid applications require the control and transport of particles immersed in a fluid. We propose a model for automatically planning good trajectories from an arbitrary point to a target in the presence of obstacles. It can be used for the manipulation of particles using actuators of mechanical or electrical type. We present the...

An experience can be defined as the triggered stimulation of the senses, the heart, and the mind. Senses play a central role in our perception of the surrounding world. Therefore, the study of the sensory dimension of tourist experiences is pivotal to visitor management in the tourism industry. In particular, recent studies showed that a successful...

The paper deals with mathematical modelling of the growth of tumours characterized by the presence of cancer stem cells (CSC). These cells are assumed to be immortal and multi-potent, in the sense that they can generate either CSC or ordinary cancer cells (CC). We present a synthetic review of some models that have been proposed in the literature a...

In this paper, we present a study which is the completion of the problem left open in the appendix of the paper Nuño et al. (Eur J Appl Math 21:459–478, 2010). The goal of the paper is to offer a deeper analysis of the type of the ODE system featured in the paper above concerning the evolution of the total wealth and cheater population and, mainly,...

The purpose of this article is to publish a basket of diierent types of indicators (key performance indicators and key result indicators) related to the strategic objectives of common interest of local authorities. Keywords: strategic planning and monitoring, strategic objectives, performance measurement, key performance indicator (KPI)

In this article we consider a mathematical model for a low porosity porous medium saturated by water, present both as the liquid and the vapor phase. In the isothermal case we propose a new formulation using a single nonlinear parabolic–hyperbolic equation for the fluid mixture density XX. We present the derivation of the unified model and a number...

Conference Paper

In this paper, we study the dynamics of a population where the individuals can either be contributors (tax payers) or no contributors (tax evaders or cheaters). We introduce a 2D cellular automaton on which the probability of transition from one of the above states to the other is the sum of the local effect and of the global field effect. The mode...

In this paper we analyze the problem of glow discharge in low pressure plasma in industrial plant, for chambers of different shapes and various working parameters, like pressure and electric potential. The model described is based upon a static approximation of the AC configuration with two electrodes and a drift diffusion approximation for the cur...

The problem is to understand how a geother-mal field can evolve from a water dominated state (i.e. when the geothermal fluid is mainly in liquid phase) into a vapour dominated one. A first answer to this question is given by a semplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by p...
