Two-pion exchange NN potential from Lorentz-invariant EFT
We outline the progress made in the past five years by the S\~ao Paulo group
in the development of a two-pion exchange nucleon-nucleon potential within a
Lorentz-invariant framework of (baryon) chiral perturbation theory.Comment: 5 pages, Talk given at the 18th International IUPAP Conference on

Spiraled channels improve heat transfer between fluids
Spiral flow channels increase heat transfer between two fluids in a countercurrent heat exchanger of given volume. The heat exchanger is constructed by connecting a spiraled bellows-shaped ducting between two concentric cylindrical tubes

Scalar form factors and nuclear interactions
The scalar-isoscalar term in the two-pion exchange potential is
abnormally large and does not respect the hierarchy of effects predicted by
chiral perturbation theory. We argue that this anomaly is associated with
non-perturbative effects, which are also present in the scalar form
factor.Comment: Talk given at the 20EFB, Pisa, Italy, September 2007. 3 pages and 4
