The effective field theory (EFT) for a toy model of nucleons interacting via a short range and a long range Yukawa potential is presented. The scattering amplitude in the S0 channel is calculated up to next-to-next-to-leading order (NNLO) using the Kaplan-Savage-Wise (KSW) power counting scheme. A particular expansion of the amplitude about the pole at low (imaginary) momentum is used to derive...

In recent years, considerable research has they take as evidence for a bank lending explored the role played by bank lending in channel. the transmission of monetary shocks. In conWe reexamine KSW's analysis. In contrast trast to the traditional Keynesian transmission to KSW's use of aggregate data, we analyze mechanism that operates strictly through inthe mix of bank and nonbank debt separatel...

The mechanism of the fluorescence quenching of aqueous thionine by various metal ions (Ce3+_, Fe2+, Mn2+, Mg2+, Cs+ and Na+) was studied at pn = 2.5. The following Stern-Volmer constants (K s v) were determined: XSv(Fe2+) == 1.13 dm3 mol -1 , Ksw(Mn2+) = 0.24 dm3 mol"1, Ksv(Ce3+) = 0.24 dm3 mol -1, i£sv(Cs~) — 0.03 dm3 mol -1 . At concentrations below 1 mol.dm -3 Na2S04 and MgS04 are very weak ...
