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?
Nine to 12 months. Your horse has injured one of the major tendons in his leg, and that`s how long your veterinarian says he`ll be laid up. As you shelve your training and competition plans for the coming year, it sounds more like a prison sentence than a prognosis.
