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.
The eggs in the following pictures are chicken eggs. Chicks develop and hatch in 21 days, whereas keets take 26-28 days. Humidity is a constant 60%. Raise to 80% the last 3 days of incubation, which would be on day 23 for guinea eggs.In most home incubators for hobbyists, this is accomplished by adding water to the second water trough in the bottom of the incubator.hicks develop and hatch in 21 days, whereas keets take 26-28 days.
