The methylniobocene carbonyl (C 5 H 5 ) 2 Nb(CH 3 )(CO) shows an unexpected lack of reactivity with respect to ligand migration. Whereas (C 5 H 5 ) 2 V(CH 3 ) has been reported to react with CO to yield the acetyl derivative (C 5 H 5 ) 2 V(OC-CH 3 )(CO) immediately...

Formerly open ground, which accumulated considerable quantities of biomass during a fallow period of several years, developed into herb-rich dry grasslands through grazing. Depending on conservation targets, accompanying management measures such as tree and shrub felling are recom-mendable. The successful...
A tradeoff exists between increasing knowledge about internal forces on one side (e.g. by isometric testing) and increasing realism of the test setting on the other side (e.g. free dynamic tests). The usefulness of strength measurement devices for the estimation of forces that act on a ...
Objective To investigate the construction and clinical application of mini picture archiving and communication systems(PACS) based on Ian in the department of radiology in small hospitals.Methods First the LAN was built with many PC to realize the data interchanging and sharing.Then instaledl the ...
The bridge superstructure, including the concrete slab, was completely prefabricated and transported to the site in one piece on a low-boarding truck. It took a mobile crane only a few hours to heave the bridge onto its supports.doi:10.1002/stab.200590171Christoph Ackermann Dipl.-IngStahlbau...

This demonstrates that the influence of fertilizers on forest insects can not be evaluated reliably except on the basis of a sequence of infestation surveys including observations on the influence of (possibly) density governing factors.doi:10.1111/j.1439-0418.1964.tb02936.xWalter Thalenhorst...
