A. POLJAKOFF-MAYBER and J. GALE The response of plants to saline
environments is of interest to people of many disciplines. In
agriculture the problem of salinity becomes more severe every year
as the non-saline soils and the non-saline waters become more
intensively and more extensively exploited. Further expansion of
agriculture must consider the cultivation of saline soils and the
use of water with a relatively high content of soluble, salts.
Moreover, industrial development in many countries is causing
severe water pollution, especially of rivers, and mismanagement in
agriculture often induces secondary salinization of soils and
sources of irrigation water. From the point of view of agriculture
it is, therefore, of the utmost importance to know the various
responses of plants to salinity and to understand the nature of the
damage caused by salinity to agricultural crops. Botanists and
plant physiologists study plants, their form, growth, metabolism
and response to external stimuli. A challenging problem for them is
to understand the differences between glycophytes, plants growing
in a non-saline environment and halophytes, plants which normally
grow in salt marshes, in sea water or in saline soils. This
includes the elucidation of structural and functional adaptations
which enable halophytes to tolerate the saline environment, and
also questions as to whether they only tolerate the saline
environment or actually thrive in it. Ecologists and
environmentalists are interested in the interrelationships be tween
the organism, in this case the plant, and its environment, from the
climatic, edaphic and biotic points of view."

History of the Universal Grinding Machine
The universal grinding machine has had so great an influence on
modern machine shop methods, and has done so much to raise the
standard of workmanship and to increase the economy of production
that a few words relating to the history of the development of this
machine may be of interest.
The origin of the modern universal grinding machine is found in the
crude grinding lathes of the early sixties. Mr. Joseph R. Brown,
senior member of the firm now known as the Brown & Sharpe Mfg.
Co., was intimately connected with the development of these
grinding lathes into the universal grinding machine. The grinding
lathe, as first built at the Brown & Sharpe Mfg. Co.'s works,
was intended for the accurate and economical manufacture of the
company's own products, and there was no idea of putting the
machines on the market. In this respect the origin and development
of the grinding machine was very much like the origin and
development of the universal milling machine. The first work for
which the grinding machines were designed was for grinding needle
bars, foot bars and shafts of the Wilcox & Gibbs sewing
machines. The first machine was built in 1864 and 1865, and one of
these early machines is still in use in the Brown & Sharpe
works. Cylindrical grinding, however, was done at the Brown &
Sharpe works as early as 1862, this being indicated by the
existence of drawings of a back-rest, dated September 22, 1862,
which contains the essential features of a solid grinding machine
back-rest of to-day.
These early machines were not grinding machines in the present
meaning of the word, but were grinding lathes using, to a
considerable extent, the parts of a 14-inch Putnam lathe. A great
number of these were sold both in this country and abroad. Mr.
Brown, however, realized the need of building a new machine
designed especially for grinding, and in 1868 the design for such a
machine was made. This design shows a machine containing most of
the essential elements of the universal grinding machine of to-day.
None of these machines were built at this time, however, on account
of the pressure of other matters, and it was first in 1874 that
working drawings were made for a complete machine containing
practically all the features of the modern universal grinding
machine. The first of these machines was exhibited at the
Centennial Exposition in...

Windham Press is committed to bringing the lost cultural heritage
of ages past into the 21st century through high-quality
reproductions of original, classic printed works at affordable
prices.
This book has been carefully crafted to utilize the original images
of antique books rather than error-prone OCR text. This also
preserves the work of the original typesetters of these classics,
unknown craftsmen who laid out the text, often by hand, of each and
every page you will read. Their subtle art involving judgment and
interaction with the text is in many ways superior and more human
than the mechanical methods utilized today, and gave each book a
unique, hand-crafted feel in its text that connected the reader
organically to the art of bindery and book-making.
We think these benefits are worth the occasional imperfection
resulting from the age of these books at the time of scanning, and
their vintage feel provides a connection to the past that goes
beyond the mere words of the text.
This is the third edition of a book that came out originally under
the title, You Can Do This Divorce, Empowerment, and Attorneys-What
You Need to Know, a primer by Nadine Larsson. Now revised and
expanded, this book continues to be a refreshingly honest memoir
about surviving divorce. Divorce, Empowerment, and Attorneys-What
You Need to Know shares the tools Ms. Larsson used to heal and
thrive in her life. Packed with useful tips on how not to get
screwed over in a divorce (hint: pick your attorney very
carefully), the author also shares her experiences with bodywork
and her discoveries about replenishing the psyche and honoring the
soul. Writer's Digest had this to say about Ms. Larsson's second
edition: "The writing is compelling with this author's inner
strength and her honesty in discussing the ways of life and human
nature in adhering to one of these basic tenets, generously shares
her wisdom in the pages of this well-organized book, displaying an
inspiring courage in the face of a divorce. Ms. Larsson presents
her personal story and observations in a way that should inspire in
ways that can only benefit any woman willing to make the leap of
faith and accept and follow her example in any area of life's
endeavors. The writing is clear and concise so as to be accessible
to the experienced reader of such books also while remaining wholly
accessible to newcomers." Other comments: "Many women live their
lives walking on egg shells, waiting for the next 'misstep' that
gets them belittled, insulted, or worse. Nadine Larsson speaks up
for all of us who have found ourselves in places of danger and
vulnerability in our own homes. I love how she has transformed her
home, and her life, into one of deep spiritual meaning and beauty "
C. Simpson. View my artwork at: www.greyhorsedreaming.com "I
couldn't put the book down once I started reading. It spoke to me
in a way no other book on this subject has. I wish I had read this
book while I was going through divorce. It would have saved me
countless pain and sorrow as I tried to come through my divorce on
my own. I am still fighting creditors looking for my ex-husband. I
did not know at the time I needed to take my name off all the joint
accounts. Bless you Nadine for trying to get this information into
the hands of women going through divorce and separation." M.
Holbrook And, from the second edition: "From the tears and sorrow
in the beginning to the triumph in the end....full of wonderful
information, thoughts, emotions, and practicality that we can
identify with. I highly recommend this book to anyone looking for
information on how to thrive over adversity. It's a powerful story
of courage and tenacity, especially for anyone moving from
surviving to thriving." Carol Barbeau, www.carolbarbeau.com. Why is
it that many attorneys seem to be less than candid and complete
with their clients? Does it almost seem sometimes as though
everything has been decided in some back room and the client is
just a pawn in a never ending game of office or inter-office
politics amongst an elite group? This book helps you to take
control of your destiny. It may be only stopping and saying,
enough, I want to understand this now. Per Ms. Larsson, in
retrospect, "there seemed to be a 'don't ask, don't tell'
conversation going on between my attorney, my husband's attorney,
and the judge. Who was really protecting my interests?" Find out
how you can protect your own interests, how you can ask better
questions--how you can better protect yourself from yourself.
Especially if you have suffered from low self-esteem or if you have
experienced even one incident of domestic violence, Divorce,
Empowerment, and Attorneys-What You Need to Know will be helpful to
you. Learn how to ask the right questions. The credit you save may
be your own.
