Hi,
I'm writing a Master's thesis on superhydrophobic surfaces aimed at preventing ice accumulation, and I'm looking for an appropriate quote to include in my introduction. Any suggestions?
Is it correct to say that a water droplet on a surface freezes by heat transfer from the droplet through the water-substrate interface, and a subsequent nucleation process whereby minute particles on the surface (or the surface roughness) acts as nucleation centers?
Do you know of a...

In this system, a single-span beam is exposed to the following stresses:
\sigma_{max}= 255 Mpa at F_{max} = 50 kN and
\sigma_{min}= 102 MPa at F_{min} = 20 kN
The stress range is accordingly \Delta\sigma =...
The current banking system allows the banks to lend out their money up to (approximately) ten times, while still allowing all deposits to be withdrawn upon demand. This is called http://en.wikipedia.org/wiki/Fractional-reserve_banking" [Broken] (FRB). One consequence of FRB is that the money...
