Plutonium is much rarer in nature than uranium and is more commonly used for bombs rather than as reactor fuel. Like uranium, it comes in various isotope forms, with plutonium 239 the most commonly used. It is mixed with the much more unstable plutonium 240 to generate power.
It's my understanding that a horse's knees close around age 2- 2 1/2. My gelding JUST turned 3. A couple days ago in fact. Will a horse's knees almost certainly be closed by that age?
Most of us know that horses can suffer from equine gastric ulcers syndrome (EGUS), a condition where horses develop ulcers in their stomachs. Horses can also develop ulcers in their large intestines. This condition is referred to as colonic ulcers or right dorsal colitis (RDC). In a recent study of 545 horses tested for RDC, 44% of nonperformance horses and 65% of performance horses had colonic ulcers. Although they are not as prevalent as gastric ulcers, colonic ulcers are still a significant problem, especially in performance horses. RDC seems to be closely associated with stress.
