Clean Soil and Safe Water (NATO Science for Peace and Security Series C: Environmental Security)
by Dragana Vidojevic Francesca F. QuerciaThis book addresses questions of relevance to governments and industry in many countries around the world, in particular concerning the link between contaminated-land-management programs and the protection of drinking water resources and the potential effects of climate changes on the availability of these same resources. On the "problem" side, it reports and analyzes methodologies and experiences in monitoring and characterization of drinking water resources (at basin, country and continental scales), pollution prevention, assessment of background quality and of impacts on safety and public health from land and water contamination and impacts of climate change. On the "solution" side, the book presents results from national cleanup programs, recent advances in research into groundwater and soil remediation techniques, treatment technologies, research needs and information sources, land and wastewater management approaches aimed at the protection of drinking water.
Clean Sweep! Frank Zamboni's Ice Machine: Great Idea Series (Great Idea Series #8)
by Monica KullingWhen Frank Zamboni, along with his brother and cousin, opened their own skating rink in 1940 in Paramount, California, it could take an hour and a half for a crew to resurface the ice. They had to level the surface by shaving down the pits and grooves with a tractor, remove the shavings, wash the ice and find a way to give the rink its shining finish. Skaters became exasperated with the wait, so Frank was determined to do something about it. Could he turn a ninety-minute job for five men into a ten-minute task for only one? Working in the shed behind his ice rink, Frank drew designs and built models of machines he hoped would do the job. For nine years, he worked on his invention, each model an improvement on the one before. Finally, in 1949, Frank tested the Model A, which "cleaned the ice in one sweep around the rink." The rest is history.
The Clean Tech Revolution: The Next Big Growth and Investment Opportunity
by Ron Pernick Clint WilderWhen industry giants such as GE, Toyota, and Sharp and investment firms such as Goldman Sachs are making multibillion-dollar investments in clean technology, the message is clear. Developing clean technologies is no longer a social issue championed by environmentalists; it's a moneymaking enterprise moving solidly into the business mainstream. In fact, as the economy faces unprecedented challenges from high energy prices, resource shortages, and global environmental and security threats, clean tech—technologies designed to provide superior performance at a lower cost while creating significantly less waste than conventional offerings—promises to be the next engine of economic growth.In The Clean Tech Revolution, authors Ron Pernick and Clint Wilder identify the major forces that have pushed clean tech from back-to-the-earth utopian dream to its current revolution among the inner circles of corporate boardrooms, on Wall Street trading floors, and in government offices around the globe. By highlighting eight major clean-tech sectors—solar energy, wind power, biofuels and biomaterials, green buildings, personal transportation, the smart grid, mobile applications, and water filtration—they uncover how investors, entrepreneurs, and individuals can profit from this next wave of technological innovation. Pernick and Wilder shine the spotlight on the winners among technologies, companies, and regions that are likely to reap the greatest benefits from clean tech—and they show you why the time to act is now.Groundbreaking and authoritative, The Clean Tech Revolution is the must-read book to understand and profit from the clean technologies that are reshaping our fast-changing world.
Clean Water and Sanitation (Encyclopedia of the UN Sustainable Development Goals)
by Walter Leal Filho Anabela Marisa Azul Luciana Brandli Amanda Lange Salvia Tony WallThe problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each devoted to one of the 17 SDGs. This volume is dedicated to SDG 6 "Ensure availability and sustainable management of water and sanitation for all". Water and sanitation are fundamental to human well-being. Integrated water resources management is essential to ensure availability and sustainable management of water and sanitation for all and to the realization of Sustainable Development.Concretely, the defined targets are:Achieve universal and equitable access to safe and affordable drinking water for allAchieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situationsImprove water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globallySubstantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity Implement integrated water resources management at all levels, including through transboundary cooperation as appropriateProtect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes Expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes, including water harvesting, desalination, water efficiency, wastewater treatment, recycling and reuse technologiesSupport and strengthen the participation of local communities in improving Uwater and sanitation managementEditorial BoardUlisses M.

Cleaner Combustion: Developing Detailed Chemical Kinetic Models (Green Energy and Technology)
by Edward Blurock Frédérique Battin-Leclerc John M. SimmieThis overview compiles the on-going research in Europe to enlarge and deepen the understanding of the reaction mechanisms and pathways associated with the combustion of an increased range of fuels. Focus is given to the formation of a large number of hazardous minor pollutants and the inability of current combustion models to predict the formation of minor products such as alkenes, dienes, aromatics, aldehydes and soot nano-particles which have a deleterious impact on both the environment and on human health. Cleaner Combustion describes, at a fundamental level, the reactive chemistry of minor pollutants within extensively validated detailed mechanisms for traditional fuels, but also innovative surrogates, describing the complex chemistry of new environmentally important bio-fuels. Divided into five sections, a broad yet detailed coverage of related research is provided. Beginning with the development of detailed kinetic mechanisms, chapters go on to explore techniques to obtain reliable experimental data, soot and polycyclic aromatic hydrocarbons, mechanism reduction and uncertainty analysis, and elementary reactions. This comprehensive coverage of current research provides a solid foundation for researchers, managers, policy makers and industry operators working in or developing this innovative and globally relevant field.

Clear Home, Clear Heart: Learn To Clear The Energy Of People And Places
by Jean HanerHave you ever entered a room and it just didn’t feel right, yet you couldn’t explain why? Do you sense a natural comfort with some people but are immediately stressed by others? The truth is that we’re all influenced far more than we realize by the invisible energy of the people and places around us. This, along with difficult experiences in your past that still weigh you down, can keep you from being a creative force in your life. Clearing is a gentle but powerful way to release the old stress you’re still carrying from your life history, as well as transform how you’re affected by the energy around you each day. Many people experience immediate shifts in their energy during a clearing, and significant change often unfolds in the days and weeks afterward. In fact, clearing has even been described as “accelerated meditation” because it can lead to a sense of calm and happiness that typically results only after years of a mindfulness practice. In this simple, elegant guide, Jean Haner teaches you, in easy-to-follow steps, how to clear your own energy or that of any person, as well as bring harmony to the energy of the spaces you inhabit, so you can reclaim your vitality and joy, and open up infinite new possibilities in life. Healers, intuitives, energy workers, highly sensitive people, and anyone who just wants to optimize their energy and live their best life will find this to be the perfect training. Jean refines energy clearing to its pure essence—the power of the compassionate heart!
Clear Skies
by Jessica Scott KerrinAs the US/Soviet Space Race heats up in 1961, eleven-year-old Arno finds his dreams of becoming an astronomer exploding like an extragalactic supernova. It is the summer of 1961, and eleven-year-old Arno Creelman wants nothing more than to be an astronomer. His claustrophobia rules out flying in a cramped space capsule, so instead, Arno dreams of exploring the galaxies with powerful telescopes back on Earth. Arno’s first move: Enter a local radio contest and win a visit to the new observatory that is about to open near his town. The ribbon will be cut by Arno’s idol, Jean Slayter-Appleton, a renowned astronomer whose weekly columns Arno clips for his own notebooks. When he finally manages to phone in and correctly answer the skill-testing astronomy question, Arno is thrilled. Then a new boy moves to the neighborhood, and he seems to challenge Arno in every way. Robert even believes in astrology, which Arno argues is not a science at all. Before long, Arno is feeling left behind, on the outs with his friends and even abandoned by his beloved dog, Comet. How did Arno’s dream become a cosmic nightmare?

Clearing the Air: Asthma and Indoor Air Exposures
by Institute of MedicineSince about 1980, asthma prevalence and asthma-related hospitalizations and deaths have increased substantially, especially among children. Of particular concern is the high mortality rate among African Americans with asthma. Recent studies have suggested that indoor exposures--to dust mites, cockroaches, mold, pet dander, tobacco smoke, and other biological and chemical pollutants--may influence the disease course of asthma. To ensure an appropriate response, public health and education officials have sought a science-based assessment of asthma and its relationship to indoor air exposures. Clearing the Air meets this need. This book examines how indoor pollutants contribute to asthma-- its causation, prevalence, triggering, and severity. The committee discusses asthma among the general population and in sensitive subpopulations including children, low-income individuals, and urban residents. Based on the most current findings, the book also evaluates the scientific basis for mitigating the effects of indoor air pollutants implicated in asthma. The committee identifies priorities for public health policy, public education outreach, preventive intervention, and further research.

Clearing the Fog: From Surviving to Thriving with Long Covid—A Practical Guide
by James C. Jackson&“An essential guide&” (Mark Hyman, author of Young Forever) to navigating life with the cognitive and mental health impairments that often accompany Long Covid. Early in the Covid-19 pandemic, the shocking mortality figures obscured the fact that death is not the only adverse outcome of the virus. Today, as many as 30 percent of Covid-19 survivors still experience symptoms long after their acute illness has passed, with cognitive and mental health problems especially prominent. For long haulers, this struggle with Long Covid has irrevocably changed their lives. Many have lost their ability to work, attend school, and look after their children. They often feel misunderstood and dismissed by others. Their once-full lives are now filled only with doctors' appointments that seem more and more futile. In Clearing the Fog, neuropsychologist Dr. James C. Jackson offers people suffering from Long Covid and their families a roadmap to help them manage their &“new normal.&” Focusing on cognitive impairment and mental health issues, he shows readers: The ways in which they can manifest and disrupt Suggestions for how and when to seek professional evaluations Science-based treatment options and strategies, Information on navigating health care systems and disability insurance Validation and hope as patients wrestle with their new diagnosis In addition, Dr. Jackson shares his own experience with chronic illness, relating to long haulers with vulnerability and compassion. Through moving stories as well as hands-on guidance, Clearing the Fog will help long haulers understand their current situation while offering multiple ways to address it, make sense of it, and move through it with the goal of thriving instead of merely surviving.
