Semi-Molten Meteoric Iron Associated with a Crop Formation
We report the unusual discovery of a natural iron "glaze" composed of fused particles of meteoritic origin, concentrated entirely within a crop formation in England, appearing shortly after the intense Perseid meteor shower in August, 1993. Physical and chemical characteristics as well as spatial distributions indicated reheating to a semi-molten state at the time of crop impact, suggesting inv...
متن کاملVLF/LF Radio Sounding of Ionospheric Perturbations Associated with Earthquakes
It is recently recognized that the ionosphere is very sensitive to seismic effects, and the detection of ionospheric perturbations associated with earthquakes, seems to be very promising for short-term earthquake prediction. We have proposed a possible use of VLF/LF (very low frequency (3-30 kHz) /low frequency (30-300 kHz)) radio sounding of the seismo-ionospheric perturbations. A brief histor...
متن کاملZeta Measure Associated to lF,[T]
The object of this paper is to identify the divided power series corresponding to the zeta measure associated to f f ,,[ r]. The first section introduces the zeta function for JF4[ T] and describes some of its interesting properties. In the second section, we describe results on interpolations and measures and state our main result (Theorem VII). The third section summarizes various results abo...
متن کاملLF in LF: Mechanizing the Metatheory of LF in Twelf
We present a mechanized proof of the metatheory of LF, i.e. the decidability of typechecking and the existence and uniqueness of canonical forms. We use a syntactic approach in which we define a translation from LF to its canonical forms presentation (in which only beta-short, eta-long terms are well-formed) and prove soundness and completeness of the translation, establishing that definitional...
متن کاملBeam Cooling with ionisation losses
This novel type of particle “cooling”, called Ionization Cooling, is applicable to slow ( ) ions stored in a small ring. The many traversals through a thin foil enhance the nuclear reaction probability, in a steady configuration in which ionisation losses are recovered at each turn by a RF-cavity. For a uniform target “foil”, typically few hundred v ≈ 0.1c μg cm thick, transverse betatron oscil...
