Why are Jupiter-family comets active and asteroids in cometary-like orbits inactive? [PDF]
, 2016 Context: Surveys in the visible and near-infrared spectral range have revealed the presence of low-albedo asteroids in cometary like orbits (ACOs). In contrast to Jupiter family comets (JFCs), ACOs are inactive, but possess similar orbital parameters ...

Meteoritics &Planetary Science, Volume 59, Issue 6, Page 1236-1257, June 2024.Abstract Cosmic dust particles originate from a wide variety of solar system and interstellar objects, including sources not identified among meteorite collections. Particles that survive atmospheric entry are retrieved on the Earth's surface as micrometeorites. The recovery of these micrometeorites has recently advanced to rooftop sites.

A survey of selected coastal vegetation communities of Florida [PDF]
, 1977 A survey of coastal vegetation around Florida was conducted during 1973 and 1974. Seventeen sites were selected and sampled using the transect method to determine species occurrence, relative densities, and habitat development and structure.
