All drinking water supplies contain some background NOM. In the early 1970s, NOM became a focus of concern as its central role in the formation of potentially carcinogenic disinfection by-products was recognized. DBPs, including the trihalomethanes (THMs) and haloacetic acids (HAAs), were found to result from the reaction of chlorine with NOM. Starting in the late 1970s, regulations were established by the USEPA with the intention of minimizing DBP exposure. These regulations stimulated the development of in-plant control strategies; however, far less attention has been paid to watershed management for precursor control. The research objectives of this study were to (1) to investigate the sources, nature, and long-term variability of natural organic matter (NOM) and biodegradable organic matter (BDOM) in source waters, and (2) evaluate their impact on the formation of disinfection by-products (DBPs). Relationship Between NOM and DBP Formation Laboratory experiments were performed on a wide range of raw waters and NOM isolates. Disinfection by-product yields were measured along with some key physico-chemical parameters. These data were blended with literature data and processed using classical power function models. The final product was a comprehensive assessment of DBP precursor densities in raw waters, and hydrophobic, mesophilic, and hydrophilic NOM fractions. Precursor Generation Laboratory tests were conducted on leachate from plant material and on pure solutions of lignin monomers. Using these data and a lignin degradation/characterization method, assessments were made of the role of lignin in DBP precursors and NOM. Other conclusions were drawn concerning the genesis of soluble precursors in forested watersheds. Modeling Synaptic surveys were conducted in watersheds from across the United States. Export modeling was conducted with the aim of attributing certain land use types or land cover to concentrations of specific DBP precursors.
This historic work reveals the inner spiritual life of one of the most beloved and important religious figures in history--Mother Teresa. During her lifelong service to the poorest of the poor, Mother Teresa became an icon of compassion to people of all religions; her extraordinary contributions to the care of the sick, the dying, and thousands of others nobody else was prepared to look after has been recognized and acclaimed throughout the world. Little is known, however, about her own spiritual heights or her struggles. This collection of her writing and reflections, almost all of which have never been made public before, sheds light on Mother Teresa's interior life in a way that reveals the depth and intensity of her holiness for the first time. Compiled and presented by Fr. Brian Kolodiejchuk, M.C., who knew Mother Teresa for twenty years and is the postulator for her cause for sainthood and director of the Mother Teresa Center, Mother Teresa brings together letters she wrote to her spiritual advisors over decades. A moving chronicle of her spiritual journey—including moments, indeed years, of utter desolation—these letters reveal the secrets she shared only with her closest confidants. She emerges as a classic mystic whose inner life burned with the fire of charity and whose heart was tested and purified by an intense trial of faith, a true dark night of the soul. "If I ever become a Saint-- I will surely be one of "darkness." I will continually be absent from Heaven-- to light the light of those in darkness on earth." --Mother Teresa
The saint wrote this luminous exposition of infused prayer in all its gradations and qualities, while she was suffering from a furious persecution. And yet it breathes that heavenly calmness peculiar to spirits dwelling in the loftier regions of heavenly peace. Like all of her writings she composed this one under a very stringent obedience from her confessor, at that time Canon Velasquez, afterwards Archbishop of Compostella. It is curiously allegorical in its framework; and yet the high topics are very plainly treated of, and they are made as intelligible to ordinary readers as is possible; all the more so, in fact, on account of the comparison she adopts between the stages of the soul's advancement in prayer, and the progress of a guest in a magnificent castle passing from its outer to its interior splendors. The style is familiar, yet the tone is stately, often even majestic. The author sheds a clear light, clear though dazzling, on the vague and distant and ravishingly beautiful states of contemplative prayer
Capturing the inner spiritual life of one of the twentieth century's most beloved religious figures, the private writings, reflections, and letters of Mother Teresa chronicle her spiritual journey, her dedication to charity, the trial of faith that tested and shaped her beliefs, and her contributions to the sick, the dying, and the forgotten. 60,000 first printing.
Experience the same Spirit-filled words that Mother Theresa shared with the poor, the dying, the hurting, and the skeptical. The quotes, stories, and prayers in this book are hers. Mother Teresa's work for -- and among -- the poor has become the yardstick by which millions measure compassion and generosity across religious and political divides. While Mother Theresa herself always stressed action over words, it is the latter that have provided solace and hope to those who never had the opportunity to meet her during her life. Though the world has lost one of its most admired women, Mother Theresa's words and her memory still serve to move men and women from every race and religious background to volunteer to help the poor. -- From publisher's description.
