BOLIDE PHYSICAL THEORY WITH APPLICATION TO PN AND EN FIREBALLS. [PDF]
, 2001 Using data on 22 'precise bolides' with up to 882 individual points on their trajectories and using data on 29 'bright bolides' and on 10 artificial meteors, we tried to derive dependence of ablation and shape-density coefficients, and of luminous ...

Automated Software for the Detection of Bolide Events [PDF]
, 2018 The proper detection and analysis of bolide events ensures that we will once day be prepared for a big, catastrophic impact by a meteor. The data obtained from the analysis of these detected smaller events will provide important information about the ...

A search for hydroacoustic signals from bolides
IcarusHere we present a survey aimed at detecting hydroacoustic signals from fireballs using the six hydrophone stations operated as part of the Comprehensive Test Ban Treaty Organisation (CTBTO) International Monitoring System. We identified 30 fireballs where propagation paths to stations exist.

New insights into the evolutionary history of biological nitrogen fixation
Frontiers in Microbiology, 2013 Nitrogenase, which catalyzes the ATP-dependent reduction of dinitrogen (N2) to ammonia (NH3), accounts for roughly half of the bioavailable nitrogen supporting extant life.
