Dialysis technicians also clean the dialysis machines before and after use. The majority of dialysis technicians are employed in hospitals and work full time. Their schedule might consist of evening, night, weekend, and holiday hours because hospitals are open 24 hours a day, 7 days a week. Some dialysis technicians work in medical clinics that offer dialysis treatments.
One of the most consistently used facts by 9/11 conspiracy theorists is that the grade of steel used in the World Trade Center simply couldn't melt at the temperatures fires created when jetliners slammed into the structures. And they're right. Steel's melting point is 2,750 degrees Fahrenheit (1510 Celsius). Yet jet fuel only burns between 800 and 1500 degrees Fahrenheit (426.7 and 815.5 Celsius) [source: Popular Mechanics].
The steel is heated about 25oC above the upper critical temperature, held for a set time and then cooled slowly in the furnace. This process is used to remove internal stresses built up as a result of cold working and fabrication processes.
