Agrometeorological information has impact on grass ecology and management (e.g. Babushkin and Lebed 2002; Lebed et al. 2004) as well as fodder crops management (examples in Vilela et al. 2003 and Kleschenko et al. 2004).

Ion-Exchange Chromatography, anion exchangers. Substances that are at least partially ionic in strongly polar eluents can be separated by this method. Separation is based on the affinity differences of ions toward their counter-ions in the ion exchange matrix and those dissolved in the eluent.

Heinz Engelhardtd consulting engineers and architects to design current state-of-the-art noise control and room acoustic measures. Special emphasis is on damping at low frequencies and using fiber-free absorbers with smooth closed surfaces, innovative tools and devices to solve acute acoustical problems.
