The phenomenon of catalysis is found in many homogeneous and
heterogeneous systems undergoing chemical change, where it effects
the rates of approach to the equilibrium state in processes as
diverse as those found in the stars, the earth's mantle, living
organisms, and the various chemistries utilized by industry. The
economies and the living standards of both developed and developing
countries depend to varying degrees upon the efficacy of their
chemical industries. Con sequently, this century has seen a wide
exploration and expansion of catalytic chemistry together with an
intensive investigation of specific, essential processes like those
contributing to life-supporting agricultures. Prime among the
latter must surely be the "fixation" of atmospheric nitrogen by
catalytic hydrogenation to anhydrous ammonia, still the preferred
synthetic precursor of the nitrogenous components of fertilizers.
In each decade contemporary concepts and techniques have been used
to further the understanding, as yet incomplete, of the catalyst,
the adsorbates, the surface reactions, and the technology of
large-scale operation. The contributors to the present volume
review the state of the art, the science, and the technology; they
reveal existing lacunae, and suggest ways forward. Around the turn
of the century, Sabatier's school was extending the descriptive
catalytic chemistry of hydrogenation by metals to include almost
all types of multiple bond. The triple bond of dinitrogen, which
continued to be more resistant than the somewhat similar bonds in
carbon monoxide and ethyne, defied their efforts."

The ability of pathogenic bacteria to adapt to various chemical,
biochemical and physical conditions within the human host and their
ability to respond to stresses generated in these environments is a
central feature of infectious diseases and the outcome of bacterial
infection. This book covers the key aspects of this rapidly
developing field, including the generation of stresses by the host
immune system, bacterial response to reactive chemicals, and
adaptation to environmental conditions of anatomical niches such as
the gut, mouth and urogenital tract. It also addresses the
increasing importance of different metal ions in the pathogenesis
and survival of specific bacteria. With chapters by active research
experts in the field, the book provides a comprehensive outline of
the current understanding of this field, the latest developments
and where future research is likely to be directed.
About the Contributor(s): Herry M. Mukdani (PhD, Chicago
Theological Seminary) is an ordained minister in the United Church
of Christ (UCC). He has recently been working on research projects
in promoting critical literacy supports, especially to Christian
leaders living in Asian countries and searching for new spaces in
order to speak their voices, naming the others theologically.
