Rhombic

On the rhomboid fossa a series of six temporary furrows appears; these are termed the rhombic grooves. ❋ Unknown (1918)

By the fifth week the dorsal part of the alar lamina bends in a lateral direction along its entire length, to form what is termed the rhombic lip (Figs. 648, 649). ❋ Unknown (1918)

If one combines the vertices created by an Icosahedron and a Dodecahedron you end up with a figure called a rhombic Triacontahedron. ❋ By Michael Morley (2010)

[2] Depending on some specific conditions, sulfur's allotropes form several distinct crystal structures, which are known as rhombic and monoclinic S ❋ Unknown (2009)

It's a set of thirty magnetic rhombic pyramids that forms a rhombic triacontahedron — one of nature's most beautiful shape. ❋ Ann Althouse (2009)

It is constructed from 30 identical rhombic steel plates. ❋ Stephen D. Covey (2009)

Many designs have been proposed, and I, personally, like a rhombic triacontahedron. ❋ Stephen D. Covey (2009)

I realized that this much mass, spinning at one G along the periphery of a sphere which is close to a rhombic triacontahedron exerts an outward force entirely equivalent to a pressure vessel, whose characteristics are well known. ❋ Stephen D. Covey (2009)

The yellow, rhombic fenugreek seed is frequently used in the preparation of pickles, curry powders and pastes, and is often encountered in the cuisine of the Indian subcontinent and Thailand. ❋ Unknown (2006)

The Ball of Whacks is a d30 - a rhombic triacontahedron, to be precise - where each face is actually the base of a separable pyramid. ❋ Unknown (2007)

After lifting the centre of the grid to the required height, l m cane pieces are placed approximately diagonally to the rhombic grid sections, in the direction of slope, and firmly tied to the grid, giving it stability. ❋ Unknown (1988)

It was of rhombic shape, with the upper and lower points long and sharp. ❋ Howard, Robert E. (1968)

These crystals have so far only been obtained as extremely small rhombic dodecahedra; their habit and symmetry suggest that here six insulin dimers may be grouped in a larger aggregate, with symmetry 23, reminiscent of structures proposed for the smaller viruses 26. ❋ Unknown (1964)

Very recently a paper was read before the Mathematical Society of London by Mrs. Bryant, Sc. D., on the geometrical form of perfectly regular cell structure, illustrated by models of cube and rhombic dodecahedron. ❋ Annie H Ryder (N/A)

The garnet is usually in the form of a rhombic dodecahedron, or as a trisoctahedron (called also sometimes an icosatetrahedron), or a mixture of the two, though the stones appear in other cubic forms. ❋ John Mastin (N/A)

Thus calcspar is in the 2nd, or hexagonal, whilst aragonite is in the 4th, the rhombic, system, yet both are the same substance, viz.: -- carbonate of lime. ❋ John Mastin (N/A)

Those in a number of systems are polymorphous, and of these sulphur may be taken as an example, since it possesses thirty or more modifications of its crystalline structure, though some authorities eliminate nearly all these, and, since it is most frequently in either the 4th (rhombic) or the 5th (monoclinic) systems, consider it as an example of dimorphism, rather than polymorphism. ❋ John Mastin (N/A)

It crystallises in the 4th (rhombic) system; in lustre it is vitreous; it is transparent, or ranging from that to translucent; the streak is white or colourless. ❋ John Mastin (N/A)

If a little more ammonia is added, several varieties of rhombic octahedra appear; if a little nitric acid is added, the rectangular prism appears again. ❋ St. George Mivart (N/A)

The chloride crystallizes in colourless rhombic tables of specific gravity 3.0 and is readily soluble in water, but is almost insoluble in concentrated hydrochloric acid and in absolute alcohol. ❋ Various (N/A)
