We report two ground-level observations, of geomagnetic storms of different origins; they are among the highest geomagnetic storms, in the solar Cycle 24. The first is St. Patrick’s Day storm on March 17, 2015, originated by the impact on Earth’s atmosphere of coronal mass ejections (CMEs), the storm reaching the condition of G4 (severe) level, in the NOAA geomagnetic scale. The second incl…
During the last years of his life, Poggio Bracciolini (1380-1459), former Apostolic Secretary and Chancellor of Florence, was working on a long text that he characterized, in a letter written in 1458, as lacking a well-defined structure. This was most probably his history of the people of Florence (Historiae Florentini populi, the title given in Jacopo’s dedication copy to Frederick of Montef…
Cellular plasticity is modulated by protein posttranslational modifications, which act on most intracellular pathways. Ubiquitination is a versatile posttranslational modification (PTM) that influences protein fate, controlling their degradation or modulating their activity and subcellular localization. The ubiquitin proteasome system, UPS, and the autophagic pathway are the main degradative in…

Defenders and critics of divine simplicity rightly look to Thomas Aquinas's important contributions to this pillar of classical theism (=CT). But few contemporary discussions notice the way Aquinas employs pseudo-Dionysius's triplex via as a principled heuristic that governs and organizes his theological enquiries concerning divine simplicity. This oversight has led to misinterpretations of Aqu…
Rivers and their watersheds constitute some of the most dynamic and complex landscapes. Rivers have sustained human communities, and human societies have utilized and altered river flows in a number of ways for millennia. However, the level of human impact on rivers, and on watershed environments, has become acute during the last hundred years or so. This book brings together empirical research…
This volume is an interdisciplinary attempt to insert a broader, historically informed perspective into current political and academic debates on the issue of evidence and the reliability of scientific knowledge. The tensions between competing paradigms, different bodies of knowledge and the relative hierarchies between them are a crucial element of the historical and contemporary dynamics of s…

In the geophysics of oil exploration and reservoir studies, the surface seismic method is the most commonly used method to obtain a subsurface model in 2 or 3 dimensions. This method plays an increasingly important role in soil investigations for geotechnical, hydrogeological and site characterization studies regarding seismic hazard issues. The goal of this book is to provide a practical guide…
Pierre-Sylvain Régis’s Cartesianism is quite singular in seventeenth-century French philosophy. Though, can we speak of a form of experimental science in Régis’s work? After exploring his notions of ‘system’ and ‘hypothesis’, I will define his position in relation to Claude Perrault, Jacques Rohault, and the Royal Society. I argue, first, that the contrasts which traverse French s…
