This paper is concerned with the existence of travelling wave solutions in a class of delayed reaction–diffusion systems without monotonicity, which concludes two-species diffusion–competition models with delays. Previous methods do not apply in solving these problems because the reaction terms do not satisfy either the so-called quasimonotonicity condition or non-quasimonotonicity condition. B...

The persuasive game, Travelling Rose, aims to enhance walking activities of elderly residents living in neighbourhoods characterized by a low socioeconomic status. The game consists of a wooden pass-on box containing user-reports and instructions on how to find a companion, how to generate a surprise together, how to give this surprise a fellow neighbourhood member, and how to pass on the Trave...

Our assumption is that the remarks made by Kant about “utility” of travel in preface Anthropology from a Pragmatic Point View fall within context modern theories, which find their point completion at end Eighteenth century. According to common sense, travelling abroad has indeed become privileged means any anthropological project; nevertheless, regards this practice useless for his own work: pa...

introduction: among the united arab emirates (uae) population more and more people now consider travelling abroad. this is potentially problematic because travelling enhances exposure between hosts and pathogens and so people that travel are putting their health at risk. this concern makes it necessary that public education is provided to inform people of the risks of travelling abroad so that ...

This paper is concerned with the asymptotic convergence of numerical solutions toward discrete travelling waves for a class of relaxation numerical schemes, approximating the scalar conservation law. It is shown that if the initial perturbations possess some algebraic decay in space, then the numerical solutions converge to the discrete travelling wave at a corresponding algebraic rate in time,...
