In Unbonded POST tension girder beam with 250 cables stressed to 70% fu, if I've got the elongation of stressed cables, what this lead to ?

if I have the elongation for each cables, its correct that the average of the elongations will be considered as girder elongation value, then I can calculate the fps for the girder. I know that...

Comparing Liposome Size: DLS Measurement vs. SEM Observation with Air Drying ?

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.
