This book is the second of two volumes that deal with discovery of chemical pathways of biosynthesis of natural products (secondary metabolites). The first volume covered the use of isotopes in biosynthetic research and the formation of enzyme cofactors and reduced polyketides. This second volume describes biosynthesis of aromatic (unreduced) polyketides, enzymes responsible for cyclization of terpenoids (isoprenoids), and biochemical generation of selected classes of alkaloids (prenylated tryptophan, tropane, pyrrolizidine). Knowledge of the pathways and the techniques to elucidate them opens the door to combinatorial biosynthesis as well as to the production of targeted pharmaceutical agents utilizing a combination of chemistry, molecular biology and protein biochemistry.

Many people know that Einstein invented the theory of relativity, but only few have more than a superficial idea of its content. This book aims to explain the basic features of relativity in detail, emphasising the geometrical aspects by using a large number of diagrams, and assuming no knowledge of higher level mathematics.

Ten years ago, Rosavine fell, and the age of Kinetic Soldiers began. They were once known as Avyars, a subspecies of humans with advantageous genetic trademarks: pupilless eyes, massive feathered wings, hollow bones, and, most importantly, a selective form of telekinesis. But ten years of torture and training have turned the survivors of Rosavine into the deadliest weapons in the world. They are now super soldiers with super powers, and every single one of them is under the command of Dr. James Traytitar. Arariel is one of Traytitar's finest specimens. Born with both aero- and hydrokinesis and now one of the most powerful Soldiers ever documented, she has etched her name across the New City in blood and destruction, but it has all been done at the bidding of others. Above all else, Arariel aims to protect those closest to her?the teammates who have become her surrogate family?and she will stop at nothing to keep them safe and secure.
