A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.
The initial shipment, in 1665, consisted of two stallions and twenty mares from the Royal Stables in Normandy and Brittany, the centre of French horse breeding.[7] Only 12 of the 20 mares survived the trip. Two more shipments followed, one in 1667 of 14 horses (mostly mares, but with at least one stallion), and one in 1670 of 11 mares and a ...
A performance test for mares or geldings is either a one-day "Field Test" or 2- to 5-week "Station Test". A stallion performance test (German: Hengsteigenleistungsprüfung) is either a 30-day "suitability test", or a "station test" lasting 70, 100, or even 300 days. Today, only young stallions owned by the State Stud of Celle attend the 300-Day ...

The practice of breeding a mare through human assisted means, with no contact between the stallion and mare. It is done for many reasons, including to protect the two animals, to allow a mare to be bred to a stallion a long distance away, [1]: 11 or to allow a stallion to be bred to a larger number of mares than would be possible via natural cover.
A stallion standing up. A stallion is a male horse that has not been gelded ().Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.
A plate-fin heat exchanger is made of layers of corrugated sheets separated by flat metal plates, typically aluminium, to create a series of finned chambers. Separate hot and cold fluid streams flow through alternating layers of the heat exchanger and are enclosed at the edges by side bars. Principal Components of a Plate Fin Heat Exchanger
Two stallions and a mare in heat are brought into the ring by human handlers. The mare is then removed, but kept in the vicinity so that her scent lingers, although in some fights she is tethered to a pole at the center of the ring. At this point, the stallions will often spontaneously attack each other.
