Dynamics of meteor streams [PDF]
The overwhelming majority of meteor streams are generally assumed to be formed due to the decay of comets. The most effective process of the release of solid particles from a cometary nucleus is their ejection by sublimating gases when the comet ...

Noûs, EarlyView.ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

New approaches to some methodological problems of meteor science [PDF]
Several low cost approaches to continuous radioscatter monitoring of the incoming meteor flux are described. Preliminary experiments were attempted using standard time frequency stations WWVH and CHU (on frequencies near 15 MHz) during nighttime hours ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees
Plant, Cell &Environment, EarlyView.ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Meteor Radar for Investigation of the MLT Region: A Review
AtmosphereThis is an introductory review of modern meteor radar and its application to the measurement of the dynamical parameters of the Mesosphere Lower Thermosphere (MLT) Region within the altitude range of around 70 to 110 km, which is where most meteors are ...

On the spatial structure of the Perseids meteor stream [PDF]
The analysis of radar observations of the Perseid meteor stream conducted in an ionospherical laboratory in the period from 1964 to 1981 is presented. The Perseids meteor rates were determined by the fluctuation method.
