Volume V deals with the problems of turnover in the nervous system.
"Turnover" is defined in different ways, and the term is used in
different contexts. It is used rather broadly in the present
volume, and intentionally so. The turnover of macromolecules is
only one aspect; here "turnover" in dicates the simultaneous and
coordinated formation and breakdown of macromolecular species. The
complexities of cerebral protein turnover are shown in aseparate
chapter dealing with the synthesis ofproteins, in another on
breakdown, and in still another on the relationship ofthese two
(showing how the two halves of turnover are controlled). The fact
that most likely the two halves of protein turnover, synthesis and
breakdown, are separated spatially and the mechanisms involved are
different further emphasizes the complexity of macromolecular
turnover. "Turnover" is used in a different context when the
turnover of a cycle is discussed; but he re again a number of
complex metabolic reactions have to be interrelated and controlled;
some such cycles are discussed briefly in this volume, additional
cycles have been discussed with metabolism, and some cycles still
await elucidation or discovery.
As far as the number of new results and quoted papers is concerned
the present book may be considered a monograph. However, it also
has some features of a textbook. Firstly, it proceeds from concrete
problems to abstract ones, and secondly, all considerations and
procedures are presented in much detail when met for the first time
(such very elementary expositions can be found especially at the
beginning of Chapters III and V). Finally, the authors focus their
attention on elementary problems which can be dealt with by
relatively simple methods. The authors hope that all this will make
it possible also for an applied or technical research worker with
some mathematical training to read this book. Naturally, the reader
is supposed to be familiar with some basic notions from
mathematical analysis, functional analysis and theory of partial
differential equations. Also, the arguments and procedures which
are repeated in the book are presented more briefly when met again,
the reader being expected to become gradually more thoroughly
acquainted with them. The authors have tried to provide a complete
bibliography of all relevant publications (their number reaches
about 500) from the theory of time-periodic solutions to non-linear
partial and abstract differential equations whose origin may be put
in the early thirties of this century.

Through a careful treatment of number theory and geometry, Number,
Shape, & Symmetry: An Introduction to Number Theory, Geometry,
and Group Theory helps readers understand serious mathematical
ideas and proofs. Classroom-tested, the book draws on the authors'
successful work with undergraduate students at the University of
Chicago, seventh to tenth grade mathematically talented students in
the University of Chicago's Young Scholars Program, and elementary
public school teachers in the Seminars for Endorsement in Science
and Mathematics Education (SESAME). The first half of the book
focuses on number theory, beginning with the rules of arithmetic
(axioms for the integers). The authors then present all the basic
ideas and applications of divisibility, primes, and modular
arithmetic. They also introduce the abstract notion of a group and
include numerous examples. The final topics on number theory
consist of rational numbers, real numbers, and ideas about
infinity. Moving on to geometry, the text covers polygons and
polyhedra, including the construction of regular polygons and
regular polyhedra. It studies tessellation by looking at patterns
in the plane, especially those made by regular polygons or sets of
regular polygons. The text also determines the symmetry groups of
these figures and patterns, demonstrating how groups arise in both
geometry and number theory. The book is suitable for pre-service or
in-service training for elementary school teachers, general
education mathematics or math for liberal arts undergraduate-level
courses, and enrichment activities for high school students or math
clubs.

"Prairies of Possibilities" is a mid-career survey of the poetic
output of a highly versatile writer whose work has been published
in more than a dozen countries in four languages. In addition to
poetry he has written histories, children's stories and memoirs. He
has received local, national, and international awards and
recognition for his work, the Robert Hayden Poetry Fellowship among
them.
Praise for his poetry has come from, among others, William
Stafford, one of America's premier poets of the twentieth century,
and fellow Kansan. "I prize your book ("Whispers Shouting Glory");
it reaches out for the elements of our lives and does so in a
context I know and cherish myself."--"Bill" Herrmann's poetry gives
an inside view of one who has overcome serious obstacles that have
defeated many others. These include the social isolation of a rural
farm, the challenges of dyslexia and ADD, and a traumatic
childhood. Despite all this, his love for God's world of nature and
the Divine shines through these poems in all their glorious beauty.
He interweaves the natural world with profound mystical
visions.
This is his ninth published collection of poems.
