Wide mediastinum is caused by aortic rupture or mediastinal hematoma, but poor radiographic technique can lead to a mistaken diagnosis. The plain chest film and the aortogram are essential for the proper diagnosis of widened mediastinum in trauma.
1 Temperature: Chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal). 2  Avoid temperatures outside the 97â103 Â°F (36â39 Â°C). 3  range. 4  If the temperature remains beyond either extreme for several days, hatchability may be severely reduced.
The correct chicken cooking temperature is critical to destroying pathogens such as Salmonella, which is extremely heat-resistant and can cause severe illness. To safely destroy dangerous bacteria the internal temperature of cooked chicken should reach no less than 165 degrees Fahrenheit. This is the minimum temperature for safe cooking, however, for maximum safety a higher chicken cooking temperature may be preferable, particularly for breast meat and whole chickens. For whole chickens 180 degrees is a safe temperature, and 170 degrees Fahrenheit is safest for chicken breasts.
