[1] While similar to dwarf elliptical galaxies in appearance and properties, dwarf
spheroidal galaxies are in general approximately spherical in shape and have a lower luminosity.
The three-dimensional scattered magnetic and electric fields for each n = 0,1,2,3 admit closed-type forms via infinite series expansions in view of
spheroidal eigenfunctions [14,15].
The shape varies from prolate
spheroidal, subprolate to prolate.
Heart-shaped leaves are 5 cm diameter with palmate venation; staminate flowers show 2 or 3 individual flowers in the apical bud (Dehgan & Webster, 1979), and the pollen grains are
spheroidal of 58 [micro]m in diameter inaperturate (Bahadur et al., 2013).
Considering a representative elastic solid cube with
spheroidal microvoids and circular microcracks, see Figure 3.
The pollen shape of Cornaceae changes between
spheroidal and prolate (Erdtman, 1952; Stafford and Heath, 1991; Perveen and Qaiser, 2002), and its aperture type is tricolporate (Chao, 1954; Wodehouse, 1959).
The proposed approximation is based on Prolate
Spheroidal Wave Functions (PSWF) of order zero.
In polar view, they were semi-angular, prolate and
spheroidal (Plate 1f, 1g).
