Ferromagnetism is a form of magnetism that can be acquired in an external magnetic field and usually retained in its absence, so that ferromagnetic materials are used to make permanent magnets. A ferromagnetic material may therefore be said to have a high magnetic permeability and susceptibility (which depends upon temperature). Examples are iron, cobalt, nickel, and their alloys. Ultimately, ferromagnetism is caused by spinning electrons in the atoms of the material, which act as tiny weak magnets. They align parallel to each other within small regions of the material to form domains, or areas of stronger magnetism. In an unmagnetised material, the domains are aligned at random so there is no overall magnetic effect. If a magnetic field is applied to that material, the domains align to point in the same direction, producing a strong overall magnetic effect. Permanent magnetism arises if the domains remain aligned after the external field is removed. Ferromagnetic materials exhibit hysteresis. In 2004, it was discovered that a certain allotrope of carbon, nanofoam , exhibited ferromagnetism. The effect dissipates after a few hours at room temperature, but lasts longer at cold temperatures. The material is also a semiconductor. It is thought that other similarly formed materials, of boron and nitrogen, may also be ferromagnetic. This new book rings together leading research from throughout the world.
There’s a new, mysterious flight of stairs outside 14-year-old Carol Tanner’s bedroom. It goes up and up and up, into the realms of sheer impossibility — just as stairs in a three-bedroomed semi-detached house on Willow Drive shouldn’t. And it’s not there all the time… One day, Carol decides to escape up those stairs, leaving her difficult life in this world for just the sort of fantasy land she so loves to read about. The trouble is, that land is dying. The Princess, who sings the sun to new life each day, has been kidnapped by the evil Necromancer, and all the heroes sent to rescue her have not come back. The days are getting darker. Can Carol, and her doleful young companion, the Dolorous Lord, do something to save this world when so many heroes have failed?
The Aboriginal Australians first arrived on the continent at least 60,000 years ago, occupying and adapting to a range of environmental conditions—from tropical estuarine habitats, densely forested regions, open plains, and arid desert country to cold, mountainous, and often wet and snowy high country. Cultures adapted according to the different conditions and adapted again to environmental changes brought about by rising sea levels at the end of the last ice age. European colonization of the island continent in 1788 not only introduced diseases to which Aborigines had no immunity but also began an enduring and at times violent conflict over land and resources. Reconciliation between Aborigines and the settler population remains unresolved. This second edition of the Historical Dictionary of Australian Aborigines contains a chronology, an introduction, an extensive bibliography, and more than 300 cross-referenced entries on the politics, economy, foreign relations, religion, and culture of the Aborigines. This book is an excellent resource for students, researchers, and anyone wanting to know more about the indigenous people of Australia.

Born in Argentina, Kenelm Murray tells the story of four Anglo-Argentines who volunteered in WWII to support the Allies. Three of those, like hundreds of others, never returned. Growing up on the pampas, the author chronicles experiences in the Argentine army, he recounts cycling across Argentina and Uruguay in the 1960s, and tells of his life on three continents, with its many twists and turns, and talks about the life and times of his extraordinary family in Europe, Chile and Argentina. His career in microelectronics in the UK, culminating with eight years as a Design Engineering Manager in Silicon Valley, is portrayed with some amusing moments, with an account of a sudden medical crisis and stories which tell of moments of euphoria when visited, fortunately, by a great deal of success.

Elizabeth Taylor's electrifying performance in Who's Afraid of Virginia Woolf? The milkshake scene in There Will be Blood. Leonardo DiCaprio's turn as Arnie in What's Eating Gilbert Grape? What makes these performances so special? Eloquently written and engagingly laid out, Murray Pomerance answers the tough question as to what makes an exceptional, or virtuosic performance. Pomerance intensively explores virtuosic performance in film, ranging from classical works through to contemporary production, and gives serious consideration to structural problems of dramatization and production, actorial methods and tricks, and contingencies that befall performers giving stand-out moments. Looking at more than 40 aspects of the virtuosic act, and using an approach based in careful meditation and discursion, Virtuoso moves through such themes as showing off, effacement, self-consciousness, performative collapse, spontaneity, acting as dream, acting and femininity, virtuosity and torture, secrecy, improvisation, virtuosic silence, and others; giving special attention to the labors of such figures as Fred Astaire, Johnny Depp, Marlene Dietrich, Basil Rathbone, Christopher Plummer, Leonardo DiCaprio, Alice Brady, Ethel Waters, James Mason, and dozens more. Numerous scenic virtuosities are examined in depth, from films as far-ranging as Singin' in the Rain and The Bridge on the River Kwai, and My Man Godfrey. As the first book about virtuosity in film performance, Virtuoso offers exciting new angles from which to view film both classical and contemporary.
Since the earliest days of British television drama, scriptwriter Nigel Kneale has been a seminal figure. His Quatermass serials for the BBC were a seismic event in the 1950s, before finding international success when adapted by Hammer Films for the big screen. Later TV plays, such as The Road, The Stone Tape and The Year of the Sex Olympics, skilfully blend elements of science fiction and the ghost story. They remain classics and Kneale himself a great influence on popular culture. Revised and updated, this new edition of Into the Unknown charts Nigel Kneale's extraordinary career, from his childhood on the Isle of Man, to his fraught days at the BBC, strange adventures in Hollywood, and his status as legend to legions of fans. It draws on a wealth of research and many hours of interviews with Kneale himself, as well as prominent admirers. These include John Carpenter, Ramsey Campbell, Grant Morrison, Russell T Davies, and Mark Gatiss and Jeremy Dyson of the League of Gentlemen.

Hanover's history is deeply intertwined with Hanover College's beginnings. Both grew from a tiny band of determined pioneers under the leadership of Williamson Dunn, who set out from Catnip Hill Road near Lexington, Kentucky, in 1809 with his wife, two children, and three slaves. Upon crossing the Ohio River, Dunn freed the slaves and founded Hanover, which was first called Dunn's Settlement. Presbyterians and Methodists played prominent roles in the fledgling community, and local historians recall a log cabin that served as an Indian trading post. At least two houses are reported to be haunted, and three others have secret hiding places, which used to lead to caves. The reader is invited to Hanover--where home seems just around the corner, and where Midwestern values of unhurried thoughtfulness set each day's pace.
Despite many years of development, risk management remains problematic for the majority of organizations. One common challenge is the human dimension, in other words, the way people perceive risk and risk management. Risk management processes and techniques are operated by people, each of whom is a complex individual, influenced by many different factors. And the problem is compounded by the fact that most risk management involves people working in groups. This introduces further layers of complexity through relationships and group dynamics. David Hillson's and Ruth Murray-Webster's Understanding and Managing Risk Attitude will help you understand the human aspects of risk management and to manage proactively the influence of human behaviour on the risk process. The authors introduce a range of models, perspectives and examples to define and detail the range of possible risk attitudes; looking both at individuals and groups. Using leading-edge thinking on self-awareness and emotional literacy, they develop a powerful approach to address the most common shortfall in current risk management: the failure to manage the human aspects of the process. All this is presented in a practical and applied framework, rather than as a theoretical or academic treatise, based on the authors' shared experiences and expertise, rather than empirical research. Anyone involved in implementing risk management will benefit from this book, including risk practitioners, senior managers and directors responsible for corporate governance, project managers and their teams. It is also essential reading for HR professionals and others interested in organizational or behavioural psychology. This second edition is updated to strengthen the understanding of individual risk attitudes and reinforce what individuals can do to manage those risk attitudes that are leading them away from their objectives. For people who want to embrace this subject, the book highlights ways forward that are proven and practical.
