These explanations come from the ambiguous meaning of the word'week'in Hebrew, which means'a heptad', or a group of seven.
12.
Some other reasons can be stated for Ka'ba-ye Zartosht being a mausoleum; one is the triad and heptad units that are seen in the Achaemenid mausoleums.
13.
IF central rods contain heptad repeats ( repeating seven residue patterns ) of hydrophobic resides that allow two different IF proteins to intertwine into a coiled-coil formation via hydrophobic interactions.
14.
The doctrine also has a physical dimension, in that each of the heptad is linked to one of the seven creations, which in ancient philosophy were the foundation of the universe.
15.
In the second half of the 19th century, Martin Haug proposed that Zoroaster himself had viewed the Amesha Spenta as philosophical abstractions and that a personification of the heptad was really a later corruption.
16.
The origin of the spring-loaded mechanism lies within the exposed gp41, which contains two consecutive heptad repeats ( HR1 and HR2 ) following the fusion peptide at the N terminus of the protein.
17.
Studies in the hematopoietic system disclosed that during endothelial to hematopoietic stem cell transition, Gpr56 is a transcriptional target of the heptad complex of hematopoietic transcription factors, and is required for hematopoietic cluster formation.
18.
P62 is a serine / threonine rich protein of ~ 520 amino acids, with tetrapeptide repeats on the amino terminus and a series of alpha-helical regions with hydrophobic heptad repeats forming beta-propeller domain.
19.
Causeless cause is synonymous with'Triad / triple manifestation, and the heptad ( i . e . seven; prajapatis ( Devas ) or Elohim, ) which continue the cosmic chain of cause and effect.
20.
In addition, the first seven days of the month of the Zoroastrian calendar are dedicated to the great heptad and to creation, acknowledging the preeminence of the Amesha Spenta and so ensuring the inculcation of their doctrine.
