In pipelines used for petroleum production and transportation, sand particles may be present in the multi-phase flow of oil and gas and water. The Acoustic Emission (AE) measurement technique is used in the field of sand monitoring and detection in t

Almost two decades ago Ľ. Kresak (Bull. Astron. Inst. Czechoslov. 29, 129–134, 1978) suggested that the Tunguska bolide might be a fragment of comet Encke, a hypothesis that Z. Sekanina criticized in a publication a few years later (Astron. J. 88,

Photometry of near-Earth asteroid 1995 HM obtained in 1995 June is reported. This object has dimensions of at most a few hundred metres. The 85 observations result in a lightcurve with an amplitude of at least two magnitudes, indicating a highly elon

In this paper we describe a new technique for measuring the speeds of individual meteors based upon the variation of the phase received in specular reflections from the meteor train prior to the meteoroid reaching the point of closestapproach to the

Numerical integrations are performed on test-particle orbits similar to those of 2PlEncke and (6063) Jason. For purely gravitational integrations, or integrations with non-gravitational forces applied of a magnitude similar to those currently observe

If the Taurid Complex asteroids (plus 2PlEncke) are derived from the fragmentation of a giant comet over the past 20-30 kyr, as we have suggested elsewhere, then we need to identify some mechanism which could cause the observed dispersion in semimajo
