A crystal system is described by three basis vectors. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system. In addition, the angles between these vectors must all be different and may not include 90°. The triclinic lattice is the least symmetric of the 14 three-dimensional Bravais ...
Severe gingivitis in dogs can further advance into periodontal disease in which the periodontal tissues begin to degrade and, if left untreated, can lead to tooth loss. [11] Studies have also shown that periodontal disease can negatively affect systemic health which impacts the overall health of the dog, therefore exhibiting the importance of ...
Rhodonite is a manganese inosilicate, with the formula (Mn, Fe, Mg, Ca)SiO 3, and member of the pyroxenoid group of minerals, crystallizing in the triclinic system. It commonly occurs as cleavable to compact masses with a rose-red color (its name comes from Ancient Greek ῥόδον (rhódon) 'rose'), often tending to brown due to surface oxidation.

The 1981 investigations of ajoite were done on a sample from the New Cornelia Mine, Ajo, with tiny crystals averaging 0.01×0.1×0.4 mm. The mineral was shown to belong to the triclinic system, but it was not clear whether the crystal class was 1 or 1.
One Kansas-area veterinarian with the Hoisington Veterinary Hospital posted about the problem on Facebook along with a disturbing photo showing a number of the tiny black-spotted insects attached ...
Calculus formation in other animals is less well studied than in humans, but it is known to form in a wide range of species. Domestic pets, such as dogs and cats, frequently accumulate large calculus deposits. [30]
