Friction and Wear in Metals (Materials Horizons: From Nature to Nanomaterials)
by Yarub Al-Douri Riyadh A. Al-SamaraiThis book focuses on tribology in manufacturing processes from the viewpoint of sliding friction fundamentals, the use of lubricants to control friction processes such as machining, drawing, rolling, extrusion, abrasive processes, and processing at micro and nanoscales. To study tribological behavior, it is essential to know the methods of measuring and describing the surface shape and roughness. The friction and wear, their corresponding coefficients, and their main mechanisms are described, including stick-slip effects, adhesion, and plowing. Adhesive, abrasive, erosive, and erosion-corrosion wear mechanisms. Friction–wear relationships are elaborated, and wear maps are presented. Surface interactions depend on the contacting materials and surface shape. It is a function of the production process and nature of parent materials that are found to be rough, where roughness is characterized by asperities of varying amplitudes and spacing. Surface interactions are dependent both on thecontacting materials and the shape of the surface. The distribution of the asperities is directional when the finishing process is direction-dependent, such as turning, milling, etc., and homogeneous for a non-directional finishing process like lapping, electro-polishing.

Friction-Induced Vibration in Lead Screw Drives
by Farid Golnaraghi Orang Vahid-AraghiFriction-Induced Vibration in Lead Screw Drives covers the dynamics of lead screw drives with an emphasis on the role of friction. Friction-induced vibration in lead screws can be the cause of unacceptably high levels of audible noise as well as loss of operation accuracy and shortened life. Although lead screw drives have a long history and their mechanical design and manufacturing aspects are very well understood, the role of friction in their dynamical behavior has not been comprehensively treated. The book draws on the vast body of work on the subject of dynamical systems with friction (such as disk brake systems) and offers said treatment, along with: · Unique coverage of modeling of multi-DOF lead screw systems with friction · Detailed analysis of negative damping, mode coupling, and kinematic constraint instability mechanisms in lead screws drives · A practical parameter identification approach for the velocity dependent coefficient of friction in lead screw drives Friction-Induced Vibration in Lead Screw Drives serves as the definitive text on the friction-induced vibration of lead screws, and includes a practical case study where the developed methods are used to study the excessive noise problem of a lead screw drive system and to put forward design modifications that eliminate the friction-induced vibrations.
Friction-Induced Vibrations and Self-Organization: Mechanics and Non-Equilibrium Thermodynamics of Sliding Contact

Friend of Science, Friend of Faith: Listening to God in His Works and Word
by Gregg DavidsonA scientist explores the harmony between Christian faith and scienceThough some Christians and many skeptics see science and Christianity as locked in a never-ending battle, geologist Gregg Davidson contends that there is tremendous harmony between Scripture and modern science. Many apparent conflicts arise when the Bible is interpreted apart from its literary and historical contexts, but when these are taken into account, most alleged clashes resolve.Proceeding from a belief that Scripture is inspired and without error and that God's creation should inform how we interpret the Bible, Davidson shows that Scripture and science need not disagree on issues like the age of the earth, Adam and Eve, Noah's flood, the origin and development of life, and numerous related topics. Rather, Christians can rejoice at how God's glory is revealed in both the Bible and the natural world.
Friendfluence: The Surprising Ways Friends Make Us Who We Are
by Carlin FloraDiscover the unexpected ways friends influence our personalities, choices, emotions, and even physical health in this fun and compelling examination of friendship, based on the latest scientific research and ever-relatable anecdotes.Why is dinner with friends often more laughter filled and less fraught than a meal with family? Although some say it's because we choose our friends, it's also because we expect less of them than we do of relatives. While we're busy scrutinizing our romantic relationships and family dramas, our friends are quietly but strongly influencing everything from the articles we read to our weight fluctuations, from our sex lives to our overall happiness levels.Evolutionary psychologists have long theorized that friendship has roots in our early dependence on others for survival. These days, we still cherish friends but tend to undervalue their role in our lives. However, the skills one needs to make good friends are among the very skills that lead to success in life, and scientific research has recently exploded with insights about the meaningful and enduring ways friendships influence us. With people marrying later--and often not at all--and more families having just one child, these relationships may be gaining in importance. The evidence even suggests that at times friends have a greater hand in our development and well-being than do our romantic partners and relatives.Friends see each other through the process of growing up, shape each other's interests and outlooks, and, painful though it may be, expose each other's rough edges. Childhood and adolescence, in particular, are marked by the need to create distance between oneself and one's parents while forging a unique identity within a group of peers, but friends continue to influence us, in ways big and small, straight through old age.Perpetually busy parents who turn to friends--for intellectual stimulation, emotional support, and a good dose of merriment--find a perfect outlet to relieve the pressures of raising children. In the office setting, talking to a friend for just a few minutes can temporarily boost one's memory. While we romanticize the idea of the lone genius, friendship often spurs creativity in the arts and sciences. And in recent studies, having close friends was found to reduce a person's risk of death from breast cancer and coronary disease, while having a spouse was not.Friendfluence surveys online-only pals, friend breakups, the power of social networks, envy, peer pressure, the dark side of amicable ties, and many other varieties of friendship. Told with warmth, scientific rigor, and a dash of humor, Friendfluence not only illuminates and interprets the science but draws on clinical psychology and philosophy to help readers evaluate and navigate their own important friendships.
Friending the Past: The Sense of History in the Digital Age
by Alan LiuCan today’s society, increasingly captivated by a constant flow of information, share a sense of history? How did our media-making forebears balance the tension between the present and the absent, the individual and the collective, the static and the dynamic—and how do our current digital networks disrupt these same balances? Can our social media, with its fleeting nature, even be considered social at all? In Friending the Past, Alan Liu proposes fresh answers to these innovative questions of connection. He explores how we can learn from the relationship between past societies whose media forms fostered a communal and self-aware sense of history—such as prehistorical oral societies with robust storytelling cultures, or the great print works of nineteenth-century historicism—and our own instantaneous present. He concludes with a surprising look at how the sense of history exemplified in today’s JavaScript timelines compares to the temporality found in Romantic poetry. Interlaced among these inquiries, Liu shows how extensive “network archaeologies” can be constructed as novel ways of thinking about our affiliations with time and with each other. These conceptual architectures of period and age are also always media structures, scaffolded with the outlines of what we mean by history. Thinking about our own time, Liu wonders if the digital, networked future can sustain a similar sense of history.

Friendship: A Natural History
by Lydia DenworthA Next Big Idea Club Must-Read Nonfiction Book of Winter 2020 A revelatory investigation of friendship, with profound implications for our understanding of what humans and animals alike need to thrive across a lifetime. The phenomenon of friendship is universal and elemental. Friends, after all, are the family we choose. But what makes these bonds not just pleasant but essential, and how do they affect our bodies and our minds? In Friendship, science journalist Lydia Denworth takes us in search of friendship’s biological, psychological, and evolutionary foundations. She finds friendship to be as old as early life on the African savannas—when tribes of people grew large enough for individuals to seek fulfillment of their social needs outside their immediate families. Denworth sees this urge to connect reflected in primates, too, taking us to a monkey sanctuary in Puerto Rico and a baboon colony in Kenya to examine social bonds that offer insight into our own. She meets scientists at the frontiers of brain and genetics research and discovers that friendship is reflected in our brain waves, our genomes, and our cardiovascular and immune systems; its opposite, loneliness, can kill. At long last, social connection is recognized as critical to wellness and longevity. With insight and warmth, Denworth weaves past and present, field biology and neuroscience, to show how our bodies and minds are designed for friendship across life stages, the processes by which healthy social bonds are developed and maintained, and how friendship is changing in the age of social media. Blending compelling science, storytelling, and a grand evolutionary perspective, Denworth delineates the essential role that cooperation and companionship play in creating human (and nonhuman) societies. Friendship illuminates the vital aspects of friendship, both visible and invisible, and offers a refreshingly optimistic vision of human nature. It is a clarion call for putting positive relationships at the center of our lives.

Frog Day: A Story of 24 Hours and 24 Amphibian Lives (Earth Day)
by Marty CrumpAn illustrated hourly guide that follows twenty-four frogs as they eat, find mates, care for their young, and survive our harsh and changing planet. In this short book, celebrated biologist Marty Crump leads readers on a worldwide field trip in search of frogs. Each chapter of Frog Day covers a single frog during a single hour, highlighting how twenty-four different species spend their time. Our day begins at midnight in Indonesia, with the rustle of leaves above. It’s not a bird, but Wallace’s flying frog, using its webbed feet and emerald-green skin flaps to glide through the forest canopy. In the early hours of the morning, we hear a horned marsupial frog “bopping” and a wood frog “quacking” to attract mates. At six o’clock in the morning, beneath a streetlight in Honolulu, we meet a corpulent, invasive cane toad slurping insects—and sometimes snakes, lizards, turtles, birds, and mice. At noon, we watch parenting in action as an African bullfrog bulldozes a path through the mud to free his tadpoles from a drying pond. At dusk, in a Peruvian rain forest, we observe “the ultimate odd couple”—a hairy tarantula and what looks like a tiny amphibian pet taking shelter in the spider’s burrow. Other frogs make a tasty meal for this tarantula, but the dotted humming frog is a friend, eating the ants that might otherwise make a meal of the tarantula’s eggs. For each hour in our Frog Day, award-winning artist Tony Angell has depicted these scenes with his signature pen and ink illustrations. Working closely together to narrate and illustrate these unique moments in time, Crump and Angell have created an engaging read that is a perfect way to spend an hour or two—and a true gift for readers, amateur scientists, and all frog fans.
