Dry mass input into fruits can be predicted by fine root morphology of pepper cultivars exposed to varied lighting spectra

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
Many pepper cultivars can be raised under artificial lighting in a plant factory. An easily measured parameter is needed to fast predict fruit loading in pepper cultivars.

Fine Spectra of Upper Triangular Triple-Band Matrices over the Sequence Space ()

open access: yesAbstract and Applied Analysis, 2013
The fine spectra of lower triangular triple-band matrices have been examined by several authors (e.g., Akhmedov (2006), Başar (2007), and Furken et al. (2010)). Here we determine the fine spectra of upper triangular triple-band matrices over the sequence

The Fine Structure of the Helium Arc Spectrum [PDF]

open access: yesProceedings of the National Academy of Sciences, 1927
Ever since its discovery the spectrum of helium has been thought to consist of singlets and doublets. Recently, however, spectroscopic theory has indicated that it should consist of singlets and triplets since helium is a two-electron system. Various attempts have been made to resolve the doublets into triplets,(1) but up to the present there have been
