Dinothrombium is a genus of mites belonging to the family Trombidiidae, which are commonly known as red velvet mites. As suggested by the name, Dinothrombium are covered in fine hairs and they are bright red, sometimes with markings in paler colors. Their bright colours appear to be aposematic, hinting at their unpleasant taste and smell. They are generally fairly large for their family and the African D. tinctorum, where adults typically are 12–14 mm (0.47–0.55 in), is one of the largest known species of red velvet mites. Dinothrombium are found in all the world's continents, except Antarctica, often in dry areas, where they spend most of the time underground in the soil or sand, emerging after heavy rain. During this time, they can be conspicuous and numerous.

The decans are 36 groups of stars used in the ancient Egyptian astronomy to conveniently divide the 360 degree ecliptic into 36 parts of 10 degrees each, both for theurgical and heliacal horological purposes. The decans each appeared, geocentrically, to rise consecutively on the horizon throughout each daily Earth rotation. The rising of each decan marked the beginning of a new decanal \"hour\" of the night for the ancient Egyptians, and they were used as a sidereal star clock beginning by at least the 9th or 10th Dynasty.

Barrotes is a computer virus, considered as the first of Spanish origin, which appeared in December 1992, and was programmed in assembly language for DOS-based systems. Initially, although to a lesser extent, it was also called Toledo by the press, due to the location in the homonymous city of its first discovery, and registered as Virus:DOS/Barrotes by Microsoft.
