(excerpt)
The evaluations of residues on foodstuffs contained in these monographs were prepared by a joint meeting of an FA0 expert committee and a WHO expert committee on pesticide residues that met in Geneva and produced its report Pesticide Residues in Food published as WHO Technical Report Series No. 545 and FA0 Agricultural Studies No. 92 in 1974.

Multifractality and Conformal Invariance at 2D Metal-Insulator Transition in the Spin-Orbit Symmetry Class
We study the multifractality (MF) of critical wave functions at boundaries
and corners at the metal-insulator transition (MIT) for noninteracting
electrons in the two-dimensional (2D) spin-orbit (symplectic) universality
class. We find that the MF exponents near a boundary are different from those
in the bulk. The exponents at a corner are found to be directly related to
those at a straight boundary through a relation arising from conformal
invariance. This provides direct numerical evidence for conformal invariance at
the 2D spin-orbit MIT. The presence of boundaries modifies the MF of the whole
sample even in the thermodynamic limit.Comment: 5 pages, 4 figure
Strange particle production in a single-freeze-out model
The transverse-momentum spectra and elliptic flow of strange particles are
calculated in the framework of the single-freeze-out model and compared with
the recent RHIC data. An overall very good agreement between the model
predictions and the data is obtained.Comment: talk presented by WF during the VIIIth Int. Conf. on Strangeness in

Weak Deeply Virtual Compton Scattering
We extend the analysis of the deeply virtual Compton scattering process to
the weak interaction sector in the generalized Bjorken limit. The virtual
Compton scattering amplitudes for the weak neutral and charged currents are
calculated at the leading twist within the framework of the nonlocal light-cone
expansion via coordinate space QCD string operators. Using a simple model, we
estimate cross sections for neutrino scattering off the nucleon, relevant for
future high intensity neutrino beam facilities.Comment: 30 pages, 11 figure
