We propose that several short-duration events observed in past stellar occultations by Chiron were produced by ring material. Some similarities between these events and the characteristics of Chariklo’s rings could indicate common mechanisms around centaurs. From a reanalysis of the stellar occultation data in the literature, we determined two possible orientations of the pole of Chiron’s rings...

it to 680•Ž in flowing nitrogen (PV-7). Four samples having different pre-heat-treatment conditions were selected; the original coke PV-7 , the second one prepared from PV-7 by the heat treatment at 1500•Ž for 60 min (PV-15) , the third also from PV-7 by the treatment at 2060•Ž for 60 min (PV-7-20) , and the fourth by the heat treatment of PV-15 at 2060•Ž for 60 min (PV-15-20). Each sample was ...

Focus particles interact with the focused constituent in a sentence. The particle only presents a challenge to formalizing this relationship as while it commonly precedes the focused constituent, only can also follow it. A syntactic account of these constructions is presented that captures the unique properties of only’s distribution within the framework presented in Kayne (1998) and offers sup...

The process-based forest growth model 4C (FORESEE FORESt Ecosystems in a Changing Environment) was used to analyze the growth of a mixed oak-pine stand [Quercus petraea (Mattuschka) Liebl., Pinus sylvestris L.]. The oak-pine stand is typical for the ongoing forest transformation in the north-eastern lowlands. The pine and the oak trees are 104 and 9 years old, respectively. Three different mana...
