(n.) An equilateral parallelogram, or quadrilateral figure whose sides are equal and the opposite sides parallel. The angles may be unequal, two being obtuse and two acute, as in the cut, or the angles may be equal, in which case it is usually called a square.
(n.) A rhombohedron.
Example Sentences:
(1) They rose steeply from DIV 3 to 8 in rhomb- and diencephalon but not in mesencephalon.
(2) Other membranes of the same cell or of other cells display either FCC only, aligned and occasionally ordered in "rhombs," "lines" only, with a similar pattern, or randomly distributed FCC.

(4) D. Perception of size: appreciation of shape in two dimentions: circle, triangle, square, cross, rhomb, appreciation of form in three dimensions: ball, column, cone, trignonal prism, cube.
(5) As models the square, the circle, the rhomb, and the equilateral triangle were used.
Rhombus
Definition:
(n.) Same as Rhomb, 1.
Example Sentences:
(1) The calculation has shown that the rounding of one of the angles of interference rhombus and its displacement towards the centre of the picture speak about either a functional deficiency of a muscle inserted into the eye ball in this place or about displacement of the point of its insertion from the limbus along the meridian of its action; displacement of one the angles of interference rhombus from the meridian speaks about displacement of the point of efforts exertion of the corresponding muscle into the same direction.
(2) Examination of eyes in a polarized light in 108 children and 24 adults with congenital concomitant convergent squint with a vertical component has shown displacement of internal angles of the rhombus of interference pictures from the horizontal axis, this speaking about anomaly of internal rectus muscles insertion.
(3) Antemolar rhombus (the anterior part of the intermolar palate) of adult Wistar rat was employed as experimental area.
(4) n. from Pungitius pungitius is near to M. paragasterostei but differs from it by the rhombus form of the spore, by less dimension of polar capsules.
(5) The figure of tetrahedron is formed in certain species of Plectus and in Tobrilus gracilis at the stage of 4 blastomeres rather than a rhombus which is formed in most highly organized nematodes.
(6) This result is taken to mean that the equilibrium constant between the two free enzyme forms (the 'circle' and the 'rhombus') is strongly dependent on temperature.
(7) If hexokinase is mixed at 4 degrees C with glucose 6-phosphate a slow increase in fluorescence of tryptophanyl residues is observed, which indicates that the 'rhombus' conformation accumulates under these conditions.
(8) Optical diffraction analysis revealed that the morphological units of both native and self-assembled S layer were essentially identical and composed of a rhombus possessing each side of 8.1 nm and interior angle of 88 degrees.
(9) Advisers to Thatcher suggested she carry a handbag and soften her voice, while Merkel got highlights, a more relaxed hairstyle and learned to deal with the issue of how to look in control by holding her hands in a rhombus shape in front of her stomach, now her trademark gesture.
(10) A rhombus-shaped skin incision around the thigh and calf, originally described by Kotz and Salzer, led to a significant discrepancy of the circumference of the proximal and distal skin borders.
(11) In the former one there are rhombus section files and triangular section files, both more flexible than old square section files.
(12) In the Mediterranean, the parasitic copepod Lepeophtheirus thompsoni Baird, 1850 specifically infests turbot (Psetta maxima L., 1758), whereas L. europaensis Zeddam, Berrebi, Renaud, Raibaut, and Gabrion, 1988 infests brill (Scophthalmus rhombus L., 1758) and flounder (Platichthys flesus L., 1758).
(13) The analysis of the Nematoda's embryogenesis allows to conclude that tetrahedron, rhombus as well as some other figures play the role of preblastula sustaining the most expedient disposition of the first blastomers for transition to the formation of the blastula.
(14) The most manifested changes in the sinus structure are noted in waterfowl and diving birds, that spend much time in flight, in dendrocolaptidae and in day predaceous birds; in them the longitudinal sinus forms a rhombus.
(15) In the most frequently observed projection form four intensity maxima were arranged at the corners of a rhombus; a cleft along the longitudinal axis of individual protomers could often be discerned.
