A mother's worst fears are almost always centered on her children. Gifts Of Grace is the compelling and true story of Deb Marcotte's worst nightmare becoming an unimaginable reality. As Deb anxiously awaited the results of the CT scan, she had almost convinced herself that her four-year-old daughter, Allie, was fine. A glance at the medical chart showed otherwise. Deb's heart sank as reality was confirmed by the doctor with words that sent her world spiraling - "It looks like she has had a stroke. But there are older strokes that are present as well." Guilt, fear, panic and an avalanche of other emotions erupted as Deb began to tearfully attempt some level of control. As she had done so many other times, Deb turned to God. Deb prayed for strength and understanding. She prayed that her faith would overcome her questions. This was the beginning of countless medical procedures in hospitals around the country. Allie would endure multiple brain surgeries and endless tests as medical experts worked to find a cure. Deb remained strong in prayer and even stronger as Allie's advocate. Gifts Of Grace is an unforgettable story of a young girl's inspiring strength, a mother's unbreakable faith and indomitable spirit, and a loving God's everlasting gifts.
NAMED A BEST BOOK OF 2023 BY PUBLISHERS WEEKLY "Revelatory, superbly written, and pulsing with wisdom and humanity, How Infrastructure Works is a masterpiece.” —Ed Yong, author of An Immense World A new way of seeing the essential systems hidden inside our walls, under our streets, and all around us Infrastructure is a marvel, meeting our basic needs and enabling lives of astounding ease and productivity that would have been unimaginable just a century ago. It is the physical manifestation of our social contract—of our ability to work collectively for the public good—and it consists of the most complex and vast technological systems ever created by humans. A soaring bridge is an obvious infrastructural feat, but so are the mostly hidden reservoirs, transformers, sewers, cables, and pipes that deliver water, energy, and information to wherever we need it. When these systems work well, they hide in plain sight. Engineer and materials scientist Deb Chachra takes readers on a fascinating tour of these essential utilities, revealing how they work, what it takes to keep them running, just how much we rely on them—but also whom they work well for, and who pays the costs. Across the U.S. and elsewhere, these systems are suffering from systemic neglect and the effects of climate change, becoming unavoidably visible when they break down. Communities that are already marginalized often bear the brunt of these failures. But Chachra maps out a path for transforming and rebuilding our shared infrastructure to be not just functional but also equitable, resilient, and sustainable. The cost of not being able to rely on these systems is unthinkably high. We need to learn how to see them—and fix them, together—before it’s too late.
This study collected information on valves, valve maintenance, and management, and developed a software modeling program for water utilities to develop cost-effective valve management plans. The model can find weaknesses in valve systems, identify critical valves and locations for the addition of new valves, and assess the impacts of the reliability of valves on customer outage. Using this model, it is possible to improve the performance of valve systems cost effectively by adding more valves in the system and improving the maintenance program, and thus, the reliability of valves. Includes CD-ROM with the Strategic Valve Management Model.
