Progress in Heterocyclic Chemistry (PHC), is an annual review series commissioned by the International Society of Heterocyclic Chemistry (ISHC). Heter Vol contain contain heter contain heter contain heter contain heter contain heter contain. Heterocyclic chemists. The highlight chapters in Volume 21 are all written in the literature. 'Biocatalytic approaches to chiral heterocycles' and 'Ring-expanded (' fat ') purines and their nucleoside / nucleotide analogues as broad-spectrum therapeutics'.
As with previous volumes in the series, Volume 21 will enable academic and industrial chemists, and advanced students, to keep abreast of developments in heterocyclic chemistry in a convenient way.
* Covers the heterocyclic literature published in 2008
* Includes specialized reviews
* Features contributions from leading researchers in their fields

The Clockwork Universe theory favored by 17th C deists held that the Earth and the heavens, and all their motions, were like a giant clock, with God as the Clockmaker. Newton\'s three laws of motion and the principle of universal gravitation were thought to be sufficient to explain phenomena of any kind, using mechanical conceptions. At Ugears we love mechanical conceptions! And so with a nod to Isaac Newton, we present the Sky Watcher Tourbillon Table Clock, a fascinating combination of imaginative celestial observatory and functional table clock! UGears 70162

The miniature digital potentiometer allows you to replace the analog potentiometer and control the resistance value using two buttons. The module contains inputs of the UP / DOWN buttons (for increasing and decreasing the resistance) and outputs in accordance with the analog potentiometer A, W, B (description on the circuit board).
