n. 1. (Crytallog.) A plane of an orthorhombic crystal which is parallel both to the vertical axis and to the shorter lateral (brachydiagonal) axis.

Order in the Triclinic System: In designating forms in the Triclinic System, most crystallographers use 1st through 4th order labels. 1st, 2nd, and 3rd order labels are applied to pinacoids that intercept two of the axes and are parallel to the third axis. 1st order denotes forms parallel to the a-axis. 2nd order is parallel to the b-axis. 3rd ...

viewed through the brachy pinacoid (a) they are grayish blue and yellow; viewed through the macro pinacoid (b) they are blue and yellow. What one sees without the dichroscope are called the "face colors. The color transmitted by. the basal plane will be a blue which is a mixture of the two axial colors belonging to the macro and brachy diagonals.

The Brachy Pinacoid. The Macro Pinacoid. The Basic Pinacoid. From the brachydomes (~a : b : mc) (or from the primary brachydome (~a : b : c), for that matter), we can derive the brachy pinacoid (~a : b : ~c) ({010}), by letting m (which equals 1 in the primary brachydome) become infinite.

pinacoid. pinacoid Applied to a crystal face which cuts the vertical c (or z) crystallographic axis and is parallel to the horizontal a (or x) and b (or y) axes. A horizontal plane of symmetry (see CRYSTAL SYMMETRY) repeats the face at the opposite end of the crystal. The resulting form is a pair of parallel faces with the index (001). pinacoid ...

In any crystal class, the general form contains the maximum number of faces that can be related by class symmetry. Figure 11.69: Some orthorhombic forms in crystal class 2/m2/m2/m. In contrast with general forms, special forms are parallel to one or two crystal axes. This means they are parallel or perpendicular to rotation axes or mirror planes.

(ii) Side or b-pinacoid (010) 2: It is an open form having two rectangular faces each of which intersects b-crystallographic axis remain parallel with the other two crystallographic axes. The symbol is (010) 2 and two faces are 010 and 010. Its old name is brachypinacoid, as both the faces are parallel with brachy- (a) axis.

Use a harness instead of a neck collar to avoid pressure on your dog's airway. Teach your dog to have self-control, keep him calm, and train him to settle down. Excitement can worsen symptoms. Avoid overfeeding to maintain a lean body condition. In general, there are no medications deemed effective in treating brachycephalic syndrome.

Minerals belong to all seven crystal systems. About 10% of the common minerals are cubic, 10% are tetragonal, 10% are triclinic, 20% are hexagonal or rhombohedral; the remainder are 25% orthorhombic and 25% monoclinic. Within each system, different point groups have different amounts of symmetry. Most natural crystals fall into the point group ...
