The study of the effects on living matter (or substances derived therefrom) of high-energy radiation extending from X-rays to gamma rays, including high energy beams of neutrons and charged particles, e.g., alpha particles, electrons, protons, deuterons. radio breakthrough The breakthrough of ...
Also it is possible using this rotation to find a universal mechanism for magnetic field generation, which can be applied for all cosmic objects from asteroids to magnetars and even galaxies, by simply assuming an excess in the positi...
The similarity of the cytoplasm to a polymer gel rather than an electrolyte liquid, has received increased attention (Pollack, 2001). Hydrogen ions in the form of protons or oxonium ions contribute to the DC conductivity of aqueous solutions by migration and hopping. Pure water exhibits a singl...
(Hint: Each of the ions has a different number of protons, but each has only one electron, so the Bohr model applies.) a. He+ with n = 5 b. F8+ with n = 2 Calculate the lattice energy for NaF (s) given the following sublimat...

Thermal diffusion of protons, deuterons and tritons forming OH, OD and OT radicals respectively was monitored by infrared absorption measurements in MgO, Al2O3, LiNbO3 and TiO2 single crystals. The electric charge and/or ionic radius is shown to be more important than mass in affecting the ...

Such a strong B→-field may be available in relativistic heavy-ion collisions, generated by the incoming protons at early times [8], [10]. Extensive theoretical and experimental efforts have been devoted to the search for the CME-induced charge separation along B→ in heavy-ion collisions [...
