The effects of the target material properties and layering on the crater chronology: the case of Raditladi and Rachmaninoff basins on Mercury

, 2011
In this paper we present a crater age determination of several terrains associated with the Raditladi and Rachmaninoff basins. These basins were discovered during the first and third MESSENGER flybys of Mercury, respectively.

Depigmented wing patch size is a condition-dependent indicator of viability in male collared flycatchers [PDF]

, 2003
Honesty of sexual advertisement is thought to be the result of signalling costs. Because production costs of depigmented plumage patches are probably very low, their role as honest signals of individual quality has been questioned. Costs of bearing these

Ages of LMC Star Clusters using ASAD$_2$

, 2016
We use ASAD$_2$, the new version of ASAD (Analyzer of Spectra for Age Determination), to obtain the age and reddening of 27 LMC clusters from full fitting of integrated spectra using different statistical methods ($\chi^{2}$ and K-S test) and a set of ...

Age Determination of Bovine Foetuses [PDF]

Acta Veterinaria Scandinavica, 1969
The need for methods for age determination of foetuses is defined. X-ray examination of the foetal head is recommended as the surest basis for age determination. Calculations are made concerning the correlation between cranial length and foetal age, and the methods used for measurements are described in detail.
