The Fluoride Deception
by Theo Colborn Christopher BrysonWith the narrative punch of Jonathan Harr's A Civil Action and the commitment to environmental truth-telling of Erin Brockovich, The Fluoride Deception documents a powerful connection between big corporations, the U.S. military, and the historic reassurances of fluoride safety provided by the nation's public health establishment. The Fluoride Deception reads like a thriller, but one supported by two hundred pages of source notes, years of investigative reporting, scores of scientist interviews, and archival research in places such as the newly opened files of the Manhattan Project and the Atomic Energy Commission. The book is nothing less than an exhumation of one of the great secret narratives of the industrial era: how a grim workplace poison and the most damaging environmental pollutant of the cold war was added to our drinking water and toothpaste.
Fluoride Removal from Groundwater by Adsorption Technology
by Abdulai SalifuIn the Eastern corridor of Northern region of Ghana, presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is, however, known about the factors contributing to the occurrence of high fluoride in this part of Ghana and it’s spatial distribution. Treatment of the fluoride-contaminated groundwater by adsorption is also hampered by the lack of suitable adsorbents that are locally available. Based on principal component analysis, and saturation indices calculations, this thesis highlights that, the predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, both of which deplete Ca from the groundwater, and promote the dissolution of fluorite. The mechanisms also include F-/OH- anion exchange processes, as well as evapotranspiration processes which concentrate the fluoride ions, hence increasing its concentration in the groundwater. Spatial mapping showed that the high fluoride groundwaters occur predominantly in the Saboba, Cheriponi and Yendi districts. The thesis further highlights that, modifying the surface of indigenous materials by an aluminium coating process, is a very promising approach to develop a suitable fluoride adsorbent. Aluminum oxide coated media reduced fluoride in water from 5. 0 ± 0.2 mg/L to ≤ 1.5 mg/L (which is the WHO health based guideline for fluoride), in both batch and continuous flow column experiments in the laboratory. Kinetic and isotherm studies, thermodynamic calculations, as well as analytical results from Fourier Transform Infrared Spectroscopy and Raman spectroscopy, suggest the mechanism of fluoride adsorption onto aluminium oxide coated media involved both physisorption and chemisorption processes. Field testing in a fluoritic community in Northern Ghana showed that the adsorbent is also capable of treating fluoride-contaminated groundwater in field conditions, suggesting it is a promising defluoridation adsorbent. The adsorbent also showed good regenerability potential that would allow re-use, which could make it practically and economically viable. Additional research is, however, required to further increase the fluoride adsorption capacity of developed adsorbent.
Fluoride Toxicity in Animals
by Rakesh Ranjan Amita RanjanThis book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.

Flush: The Remarkable Science of an Unlikely Treasure
by Bryn NelsonFor readers of Giulia Enders&’ Gut and Bill Bryson&’s The Body, a surprising, witty and sparkling exploration of the teeming microbiome of possibility in human feces from microbiologist and science journalist Bryn Nelson.The future is sh*t: the literal kind. For most of human history we&’ve been, well, disinclined to take a closer look at our body&’s natural product—the complex antihero of this story—save for gleaning some prophecy of our own health. But if we were to take more than a passing look at our poop, we would spy a veritable cornucopia of possibilities. We would see potent medicine, sustainable power, and natural fertilizer to restore the world&’s depleted lands. We would spy a time capsule of evidence for understanding past lives and murderous ends. We would glimpse effective ways of measuring and improving human health from the cradle to the grave, early warnings of community outbreaks like Covid-19, and new means of identifying environmental harm—and then reversing it.Flush is both an urgent exploration of the world&’s single most squandered natural resource, and a cri de coeur (or cri de colon?) for the vast, hidden value in our &“waste.&” Award-winning journalist and microbiologist Bryn Nelson, PhD, leads readers through the colon and beyond with infectious enthusiasm, helping to usher in a necessary mental shift that could restore our balance with the rest of the planet and save us from ourselves. Unlocking poop&’s enormous potential will require us to overcome our shame and disgust and embrace our role as the producers and architects of a more circular economy in which lowly byproducts become our species&’ salvation. Locked within you is a medicine cabinet, a biogas pipeline, a glass of drinking water, a mound of fuel briquettes; it&’s time to open the doors (carefully!). A dose of medicine, a glass of water, a gallon of rocket fuel, an acre of soil: sometimes hope arrives in surprising packages.

Fluvial Hydrodynamics
by Subhasish DeyThe state-of-the-art in fluvial hydrodynamics can be examined only through a careful exploration of the theoretical development and applied engineering technology. The book is primarily focused, since most up-to-date research findings in the field are presented, on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows. It begins with the fundamentals of hydrodynamics and particle motion followed by turbulence characteristics related to sediment motion. Then, the sediment dynamics is analysed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and scale models. It is intended to design as a course textbook in graduate / research level and a guide for the field engineers as well, keeping up with modern technological developments. Therefore, as a simple prerequisite, the background of the readers should have a basic knowledge in hydraulics in undergraduate level and an understanding of fundamentals of calculus.
Fluvial Processes: 2nd Edition (IAHR Monographs)
by Ana Maria da Silva M. Selim YalinA stream flowing in alluvium deforms its bed surface, forming ripples, dunes, bars, etc., and, in many instances, it deforms its channel entirely, thereby creating meandering or braiding patterns. It could be said that, in general, an alluvial stream and its deformable boundary undergo a variety of fluvial processes leading to the emergence of a multitude of alluvial forms. This book concerns the physics and analytical treatment of various fluvial processes and the associated alluvial bed and plan forms listed above. Following an introductory chapter on the basics of turbulent flow and sediment transport, the book covers the origin, geometric characteristics and effects of bed forms, from small- to meso-scale (ripples, dunes, alternate and multiple bars); the initiation, geometry and mechanics of meandering streams; the computation of flow, bed deformation and the planimetric evolution of meandering streams; and braiding and delta formation. The book also covers the regime concept, the time-development of a stream towards its regime state, and the formulation of stable, or equilibrium, morphology. The book distinguishes itself by its comprehensive analysis and discussion of key processes involved in large-scale river morphodynamics. The book was written primarily for researchers and graduate students of hydraulic engineering, water resources and related branches of earth sciences, but it will also prove useful for river engineers and managers.
Fluvial Systems in the Anthropocene: Process, Response and Modelling
by Aznarul Islam Prakriti Das Sandipan Ghosh Abarna Mukhopadhyay Ayan Das Gupta Arun Kumar SinghThis book addresses the various factors affecting fluvial systems, the processes governing them, system responses arising from human-nature interventions, and geospatial and geo-ecological modeling to understand system behaviour better and restore degraded ecosystems around the globe. Thanks to their hydrological and agro-ecological advantages, humans have settled along riverbanks since the dawn of civilization. Thus, the ancient "ecumene" (settlements) were located near major rivers worldwide. This legacy of river-based civilizations continues to this day in many forms. However, in the course of the 'Anthropocene' era, countless fluvial systems have been altered by human interventions in the form of large-scale dams and barrages, changes in land use and land cover, road-stream crossings, mining of sand and gravel, mushrooming of brickfield, expansion of modern agriculture, industrial growth, and urbanization. Thus, the present-day development pattern threatens fluvial systems, especially riverine morphology and ecosystems. In brief, human-induced morphological changes, water pollution, eutrophication, and related damages to aquatic organisms are the major threats to fluvial systems. Thus, maintaining the 'environmental flow' of the world's major rivers to preserve the proper functioning of riverine ecosystems and promote sustainable development is a global challenge.
Flux-Corrected Transport
by Dmitri Kuzmin Rainald Löhner Stefan TurekAddressing students and researchers as well as Computational Fluid Dynamics practitioners, this book is the most comprehensive review of high-resolution schemes based on the principle of Flux-Corrected Transport (FCT). The foreword by J.P. Boris and historical note by D.L. Book describe the development of the classical FCT methodology for convection-dominated transport problems, while the design philosophy behind modern FCT schemes is explained by S.T. Zalesak. The subsequent chapters present various improvements and generalizations proposed over the past three decades. In this new edition, recent results are integrated into existing chapters in order to describe significant advances since the publication of the first edition. Also, 3 new chapters were added in order to cover the following topics: algebraic flux correction for finite elements, iterative and linearized FCT schemes, TVD-like flux limiters, acceleration of explicit and implicit solvers, mesh adaptation, failsafe limiting for systems of conservation laws, flux-corrected interpolation (remapping), positivity preservation in RANS turbulence models, and the use of FCT as an implicit subgrid scale model for large eddy simulations.
Flux Pinning in Superconductors (Springer Series in Solid-State Sciences #198)
by Teruo MatsushitaThis book covers the flux pinning mechanisms and properties and the electromagnetic phenomena caused by the flux pinning common for metallic, high-Tc and MgB2 superconductors. The condensation energy interaction known for normal precipitates or grain boundaries and the kinetic energy interaction proposed for artificial Nb pins in Nb-Ti, etc., are introduced for the pinning mechanism. Summation theories to derive the critical current density are discussed in detail. Irreversible magnetization and AC loss caused by the flux pinning are also discussed. The loss originally stems from the ohmic dissipation of normal electrons in the normal core driven by the electric field induced by the flux motion.The influence of the flux pinning on the vortex phase diagram in high Tc superconductors is discussed, and the dependencies of the irreversibility field are also described on other quantities such as anisotropy of superconductor, specimen size and electric field strength. Recent developments of critical current properties in various high-Tc superconductors and MgB2 are introduced.The 3rd edition has been thoroughly updated, with a new chapter on critical state model. The mechanism of irreversible properties is discussed in detail. The author provides calculations of pinning loss by the equation of motion of flux lines in the pinning potential and hysteresis loss. The readers will learn why the resultant loss is of hysteresis type in spite of such mechanism. This book aims for graduate students and researchers studying superconductivity as well as engineers working in electric utility industry.

A Fly For The Prosecution: How Insect Evidence Helps Solve Crimes
by M. Lee GoffThe forensic entomologist turns a dispassionate, analytic eye on scenes from which most people would recoil--human corpses in various stages of decay, usually the remains of people who have met a premature end through accident or mayhem. To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers. Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death. An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.
Fly Girls Young Readers’ Edition: How Five Daring Women Defied All Odds and Made Aviation History
by Keith O'BrienFrom NPR correspondent Keith O’ Brien comes this thrilling Young Readers' edition of the untold story about pioneering women, including Amelia Earhart, who fought to compete against men in the high-stakes national air races of the 1920s and 1930s—and won. In the years between World War I and World War II, airplane racing was one of the most popular sports in America. Thousands of fans flocked to multiday events, and the pilots who competed in these races were hailed as heroes. Well, the male pilots were hailed. Women who flew planes were often ridiculed by the press, and initially they weren’t invited to race. Yet a group of women were determined to take to the sky—no matter what. With guts and grit, they overcame incredible odds both on the ground and in the air to pursue their dreams of flying and racing planes.Fly Girls follows the stories of five remarkable women: Florence Klingensmith, a high‑school dropout from North Dakota; Ruth Elder, an Alabama housewife; Amelia Earhart, the most famous, but not necessarily the most skilled; Ruth Nichols, a daughter of Wall Street wealth who longed to live a life of her own; and Louise Thaden, who got her start selling coal in Wichita. Together, they fought for the chance to race against the men—and in 1936 one of them would triumph in the toughest race of all. Complete with photographs and a glossary, Fly Girls celebrates a little-known slice of history wherein tenacious, trail-blazing women braved all obstacles to achieve greatness.

Fly Me to the Moon: An Insider's Guide to the New Science of Space Travel
by Edward BelbrunoWhen a leaf falls on a windy day, it drifts and tumbles, tossed every which way on the breeze. This is chaos in action. In Fly Me to the Moon, Edward Belbruno shows how to harness the same principle for low-fuel space travel--or, as he puts it, "surfing the gravitational field." Belbruno devised one of the most exciting concepts now being used in space flight, that of swinging through the cosmos on the subtle fluctuations of the planets' gravitational pulls. His idea was met with skepticism until 1991, when he used it to get a stray Japanese satellite back on course to the Moon. The successful rescue represented the first application of chaos to space travel and ushered in an emerging new field. Part memoir, part scientific adventure story, Fly Me to the Moon gives a gripping insider's account of that mission and of Belbruno's personal struggles with the science establishment. Along the way, Belbruno introduces readers to recent breathtaking advances in American space exploration. He discusses ways to capture and redirect asteroids; presents new research on the origin of the Moon; weighs in on discoveries like 2003 UB313 (now named Eris), a dwarf planet detected in the far outer reaches of our solar system--and much more. Grounded in Belbruno's own rigorous theoretical research but written for a general audience, Fly Me to the Moon is for anybody who has ever felt moved by the spirit of discovery.
Flying Blind
by Don MitchellWhen Middlebury writing professor Don Mitchell was approached by a biologist with the Vermont Fish and Wildlife Department about tracking endangered Indiana bats on his 150-acre farm in Vermonts picturesque Champlain Valley, Mitchells relationship with bats--and with government--could be characterized as distrustful, at best. But the flying rats, as Mitchell initially thinks of them, launched him on a series of "improvements" to his land that would provide a more welcoming habitat for the bats--and a modest tax break for himself and his family. Whether persuading his neighbors to join him on a "silent meditation," pulling invasive garlic mustard out of the ground by hand, navigating the tacit ground rules of buying an ATV off Craigslist, or leaving just enough honeysuckle to give government inspectors "something to find," Mitchells tale is as profound as it is funny--a journey that changes Mitchells relationship with Chiroptera, the land, and, ultimately, his understanding of his own past. Ruminating on the nature of authority, the purview of the state, and the value of inhabiting ones niche--Mitchell reveals much about our inner and outer landscape, in this perfectly paced and skilled story of place.
Flying Cars: The True Story
