These should be cooked quickly over a high heat. As Cerberus has suggested, if you are cooking something else in the same pan, take the beef out and re-add it later; don't boil it in a sauce. Stewing beef needs some fat and cartilage which breaks down during slow cooking and tenderises the meat.
Missing from the table (which will be corrected in the next edition) is the incubation period of Ebola virus, which is 2 to 21 days. I would also argue that the incubation period of HIV is not 1-10 years, but 2-4 weeks, the time until the prodromal symptoms occur.
Hatching can take place over several days. For chickens, run the incubator for 24 days (3 days more than normal hatch time). For ducks and turkeys run the incubator for 32 days (4 days more than normal hatch time).
