Influence of gravity on the collective molecular dynamics of liquid water: the case of the floating water bridge
Quantum electrodynamics (QED) produces a picture of liquid water as a mixture
of a low density coherent phase and an high density non-coherent phase.
Consequently, the Archimedes principle prescribes that, within a gravitational
field, liquid water should be made up, at surface, mainly of the coherent
fraction, which becomes a cage where the gas-like non-coherent fraction is
trapped, acquiring a non-vanishing pressure (vapor tension). Therefore, it is
possible to probe the QED picture by observing the behavior of liquid water
under reduced gravity conditions. The floating water bridge could be a useful
test model.Comment: 5 page
Italian Open End Mutual Fund Costs
We investigate the costs investors incur when they hold shares of Italian open end mutual funds. The overall explicit cost can range from less than 50 to well over 250 basis points in terms of assets under management. Nevertheless, mutual funds investors seem to be almost unaware of the importance of costs and tend to focus mainly on the net return when making their investment decisions. We measure the overall costs of a large sample of mutual funds managed by Italian intermediaries in the period 2000-2003 and also evaluate the determinants of cost efficiencies for the period 2000-2003.mutual fund expenses, total expense ratio, mutual fund transaction costs, economies of scale
DNA waves and water
Some bacterial and viral DNA sequences have been found to induce low
frequency electromagnetic waves in high aqueous dilutions. This phenomenon
appears to be triggered by the ambient electromagnetic background of very low
frequency. We discuss this phenomenon in the framework of quantum field theory.
A scheme able to account for the observations is proposed. The reported
phenomenon could allow to develop highly sensitive detection systems for
chronic bacterial and viral infections.Comment: Invited talk at the DICE2010 Conference, Castiglioncello, Italy

La vera storia dell'arresto di Giordano Bruno
L’indagine condotta su alcuni personaggi finora rimasti nell’ombra, ma che ebbero un peso notevole, se non determinante, sul destino del filosofo, permette di ricostruire il complotto ordito dall’Inquisizione Cattolica per arrivare a mettere le mani su Giordano Bruno. La minuziosa e circostanziata ricostruzione dei fatti si integra perfettamente con altre recenti ricerche dello stesso genere
