Charge and mass transfer in ice-ice collisions: Experimental observations of a mechanism in thunderstorm electrification
A microphysical mechanism that may be important in the electrification of thunderstorms is probed in an experimental study of collisional charging of ice surfaces. The study examined mass and charge transfer in single collisions between two ice samples and their dependence on growth, temperature, impact strength, and time delay between impacts. The polarity is consistent with earlier esults in ...
متن کاملThe reversal sign.
To cite: Gaete D, LopezRueda A. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204419 DESCRIPTION A 75-year-old man with a history of chronic obstructive pulmonary disease was found in cardiopulmonary arrest. After successful resuscitation the patient was transferred to our institution. On arrival, a non-enhanced brain CTwas performed to assess brain damage, ...
متن کاملA possible new molecular mechanism of thundercloud electrification
It is well established that electrification occurs when charge is transferred between small and large ice particles colliding in a thundercloud that contains strong updrafts. The small ice particles rise with one type of charge and the large ice particles (graupels) fall and carry with them downward the other type of charge, which is most often negative, so that normally lightning lowers negati...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملThe Reversal of the Sign of the Charge of Collodion Membranes by Trivalent
The reversal of the sign of charge of collodion membranes (treated previously with a protein) by hydrogen ions has been discussed in a preceding paper 1 and in this paper the influence of trivalent cations on the reversal will be considered. We shall omit the discussion of the action of tetravalent cations (e.g. ThC14) since their soiutions have so high a concentration of hydrogen ions that thi...
