描述Modern liquid column chromatography (LC) has developed rapidly since 1969 to become a standard method of separation. If the statisticians are to be believed, the recent growth of LC has been the most specta­ cular development in analytical chemistry and has not yet abated be­ cause its vast potential for application remains to be fully exploit­ ed. Significant factors contributing to this continued rise are the simplicity and low cost of the required basic equipment and the rela­ tive ease of acquiring and interpreting the data. Unfortunately, in LC, as so often in the field of analytical chemistry, the available commercial instruments are frequently far more complicated - and consequently far more expensive - than is nec­ essary for routine application. Therein also lies the risk of propa­ gating a "black box" philosophy that would be particularly detrimen­ tal to chromatography. Moreover, it appears to have been forgotten, as was done previously with gas chromatography, that inadequate sep­ aration by a column can be remedied only with great difficulty, if at all, by electronic means. Also, whether the capillary columns recent­ ly advocated with great enthusiasm for LC will fulfi

Farmers have built a strong knowledge base from practical experiences (Balasubramanian et al. 1998) gained over generations and this knowledge has to be valued for potential gain in farming.

Heinz Engelhardtoolean algebras in modeling and simplifying switching or relay circuits. This application will be described in §1. It should be noted that the algebra of switching circuits is not described because of its primary importance today but rather for historical reasons since it represented one of the firs

Heinz Engelhardt, pointing out the special low-frequency problem. The following Chaps. 4–9 present an up-to-date overview of different effects and designs of state-of-the-art as well as some novel marketable airborne sound absorbers, focusing on classifying and describing the physical damping mechanisms, which diff
