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.

The increase of women's labor force participation, the diversity of family constellations, many men's increased participation in childcare, and the development of flexible working arrangements have stimulated research on the relationship between work and non-work. In this thesis, the interaction between work and non-work is examined in the case of home-based telework, an example of flexible working arrangement. Because of the disappearance or blurring of the traditional boundaries in time and space, the consequences of these working conditions for individuals need to be analyzed. The overall aim of this thesis was to study the interaction between work and non-work in home-based telework and to analyze the following issues: - conflict versus facilitation as related to the segmentation and integration of work/non-work domains - the nature and role of boundaries - the physical and mental aspects of work activities within the domains. The results show the importance of boundaries, as they are needed in order to bring structure and legitimacy to the work (carried out in the home/private domain) and to detach from work.
