Topics in calculus and geometry on metric spaces

2022

In this thesis we present an overview of some important known facts related to topology, geometry and calculus on metric spaces. We discuss the well known problem of the existence of a lipschitz equivalent metric to a given quasiultrametric, revisiting known results and counterexamples and providing some new theorems, in an unified approach. Also, in the general setting of a quasi-metric doubling space, suitable partition of unity lemmas allows us to obtain, in step two Carnot groups, the well known Whitney’s extension theorem for a given real function of class C^m defined on a closed subset of the whole space: this result relies on relevant properties of the symmetrized Taylor’s polynomial…

Applying health promoting sports club standards in the Netherlands

2014

This study explores health promotion activity of Dutch sports clubs by using the Health Promoting Sports Clubs (HPSC) standards, which are developed in Finland and here applied to the Dutch sports context. The standards consist of 23 items which cover different perspectives on health promotion. The standards form an overall HPSC index, which is used to create health promotion profiles for the sports clubs. 17 sports clubs from the municipality of ‘s-Hertogenbosch participated in this study, of which 42 club officials (1-6 per club) evaluated their own club on all HPSC standards on a five-point Likert scale. Per club, the average score on each standard was calculated. The average on the HPSC…

Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)

2021

International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …
