There are multiple definitions:
Transcatheter Hartklep Interventie(Dutch)
temperature–humidity index(English)
- thermal method to assess heat stress adaptations and performance in animals, notably cattle, by measuring changes in core body temperature (e.g., rectal, vaginal, rumen temperature, etc.). Identifying specific genetic variants that increase tolerance to heat may help to improve dairy breeding programs in addition to improving our knowledge of the thermal biology in other mammals. However, except for mutations in the SLICK locus11, the identification of the specific genetic variants for heat tolerance in cattle and other species has, in most cases, remained elusive
