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].
Some metals melt at lower temps than others. Tin becomes liquid at 231.8ËC (447.8Ë F); at the other end of the spectrum, tungsten has the highest melting point of any metal: 3,422Ë C (6,192Ë F). Somewhere in the middle is mercury, which stays in a liquid state until its temperature drops to -40Â°. âA metal is full of bonds between the atoms that make it up,â explains Carter. âWhat determines a materialâs melting point has everything to do with the energy associated with the bonds.
