RESUMO
Self-assembled monolayer films based on iodobenzoyloxy-functionalized resorc[4]arenes were prepared on gold substrates to serve as model systems for future time-resolved studies of molecular recognition, a mechanism of outstanding importance in bioorganic systems. The film properties were tested using X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and imaging ellipsometry. An apparatus for time-resolved electron spectroscopy utilizing femtosecond soft X-ray pulses is capable of detecting iodine core-level photolines and the photoinduced dissociation after ultraviolet illumination. The developed technique holds promise for tracking the temporal evolution of chemical shifts of atomic markers as local probes for the dynamics of the guest-host interaction.

Starting from the general provisions of Section 24 federal law concerning nature conservation the essential contents of different provisions of land law about licence of animal preserves are summarized and cleared up. Sectors of priority are the interpretation and exact definition of the term "animal preserve", explanation of special licensing requirements of law concerning protection of animals (housing and feeding must be adequate to standards of conduct; rearing of animals must be competent), and considerations about lawful contents as well as legal investigations of the definitive administrative act.
