Supernova nucleosynthesis. Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes. Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.
While the AKC requires poodles competing in the standard class to be over 15 inches at the shoulder, most average around 22 to 26 inches. Dogs marketed as royal or giant run from 25 to 31 inches tall at the shoulder. While some breeders charge a premium for larger dogs, they are registered with the AKC as a standard poodle. There is no advantage to their size in the show ring.
Goldendoodles currently come in several varieties, none of which are universally recognized. The Standard Goldendoodle is the largest and most common variety, being over 21 inches in height and typically weighing over 50 pounds. The Medium variety ranges from 17 to 21 inches at the shoulder and normally weighs between 35 and 50 pounds. The Miniature Goldendoodle is between 14 and 17 inches in height and weighs from 25 to 35 pounds. The Petite variety should be less than 14 inches tall and weigh less than 25 pounds.
