One of the world's greatest fairy tales is re-told in a
graphic-novel format. In a far-away kingdom, there lives an Emperor
who prizes fancy clothes above all else. He buys suit after suit
made of the most expensive materials instead of tending to his
threadbare kingdom. Then, one day, two travelling merchants offer
to make the Emperor a special suit that has magical powers. The
merchants, however, are not who they claim to be, and the suit has
one major flaw, no one can see it!
Ligand-gated ion channels mediate fast synaptic transmission in the
central nervous s- tem (CNS) and at ganglionic and neuromuscular
synapses. The nicotinic acetylcholine - ceptor (nAChR) is a member
of the ligand-gated ion channel superfamily, which includes the
5-HT , glycine and GABA type A and C receptors. These receptors are
known as Cys- 3 loop receptors, as all of them have a conserved
sequence containing a pair of cysteines separated by 13 residues
and linked by a disulfide bridge. nAChRs can be divided into two
groups: muscle receptors, which are found at the skeletal
neuromuscular junction where they mediate neuromuscular
transmission, and neuronal receptors, which are found throughout
the peripheral and central nervous system. Many of the early
studies carried out on the subunit composition and structure of the
nAChRs were performed on receptors isolated from the electric organ
of Torpedo californica, as this tissue is very rich in nAChRs, and
they were found to have a high degree of homology with the
embryonic v- tebrate muscle type receptor. Muscle nAChRs are made
up of five subunits arranged around a central pore (Fig. 1A, B). In
Torpedo electric organ and vertebrate fetal muscle, the subunit
composition is (a1) b1gd, and in adult muscle the g subunit is
replaced by the e to give an (a1)b1ed 2 2 composition (Mishina et
al. 1986).
These exciting new companion handbooks are the only ones of their
kind devoted solely to the effects of environmental variables on
the physiology of the world's major fruit and nut crops. Their
cosmopolitan scope includes chapters on tropical and temperate zone
species written by scientists from several continents. The
influence of environmental factors, such as irradiance,
temperature, water and salinity on plant physiology and on
vegetative and reproductive growth, is comprehensively discussed
for each crop. In addition to being a thorough and up-to-date set
of textbooks, the organzation of the two volumes makes them an
excellent reference tool. Each chapter focuses on a single crop, or
a group of genetically or horticulturally related crop, and is
appropriately divided into subsections that address individual
environmental factors. Some chapters emphasize whole-plant
physiology and plant growth and development, while other chapters
feature theoretical aspects of plant physiology. Several chapters
provide botanical background discussions to enhance understanding
of the crop's response to its environment.
One of the world's greatest fairy tales is re-told in a
graphic-novel format. In a far-away land, perched upon her little
nest, Mother Duck waits for her last remaining egg to hatch. When
the odd little egg finally breaks open, Mother Duck is shocked to
see an ugly duckling staring up at her. Despite its homeliness,
Mother Duck adores her awkward child and does her best to protect
him. Unfortunately, no one else on the farm wants anything to do
with the Ugly Duckling, and he is driven from the farm to fend for
himself. Survival, however, takes more than good looks, and the
plucky little duck plods bravely into the wilderness.
Originally published in 1928, this book presents an account
regarding the formal qualities of poetry. The text begins with a
discussion of the fundamental nature of poetry, before moving into
a more detailed analysis of metrical and stylistic techniques.
Extensive quotation is used to back up all observations. This book
will be of value to anyone with an interest in poetic form and
method.
