This emission, which was unlike that characteristic of any known element, had previously been attributed to a hypothetical element, "nebulium".
Although germanium was not discovered until 1886 by Clemens Winkler, a German chemist, its existence, properties, and position in the periodic system had been predicted in 1871 by the Russian chemist Dmitry Ivanovich Mendeleyev, who called the hypothetical element ekasilicon.
There is a tendency in school science to present the evidence for evolution as uniformly convincing and all-encompassing, failing to distinguish between what is directly observable – such as change and adaptation over time through natural selection – and the more hypothetical elements, like the descent of all living things from a common ancestor.
By performing hypothetical element-exchange reactions between the system and an external element-bath, chemical potential Δμ of chain-elements, measured from its topological equilibrium value, is computed numerically as a function of condensation ratio χ of LKs.
Goethe's influence and Neurath's romantic inheritance are manifest in two areas, morphology and historiography: holism, historical conditioning, role of pictures and metaphorical language in carrying physical theory and argument (ON 1973, 102-3), rofe of language, and thereby hypothetical elements, in establishing facts (Zemplen 2006).
Those genes having a putative ortholog in the sporopollenin pathway of Arabidopsis and others showing LTP or GRP domains (Table 1) have been placed on a schematic picture depicting the hypothetical elements of this pathway in peach.
He gave these still-hypothetical elements names like "ekasilicon," "ekaaluminum" and "ekaboron," based on their expected similarities to known substances; the spaces were filled by germanium, gallium and scandium, respectively.
At the conclusion of this study, 65 coding elements including ten hypothetical genes/coding elements, nine snoRNAs and one microRNA were identified as mapping within Skts5 (see Additional file 1).
Nebulium, hypothetical chemical element whose existence was suggested in 1868 by the English astronomer Sir William Huggins as one possible explanation for the presence of unidentified (forbidden) lines (at 3,726, 3,729, 4,959, and 5,007 angstroms wavelength) in the spectra of gaseous nebulae.
The formulation has two unique aspects: First, the theory is mathematically rigorous since no assumptions are made regarding the physical behavior at a damage location, therefore there is no need to substitute the damage with a hypothetical elastic element such as a spring.
Hypothetical transposable element proteins were identified by BLASTX algorithm against TREP hypothetical protein and NCBI non-redundant protein databases.
