• Sommario/riassunto: New nanomaterials are leading to a range of emerging dental treatments that utilize more biomimetic materials that more closely duplicate natural tooth structure (or bone, in the case of implants). The use of nanostructures that will work in harmony with the body's own regenerative processes (eg, to restore tooth structure or alveolar bone) are moving into clinical practice. This book brings together an international team of experts from the fields of nanomaterials, biomedical engineering and dentistry, to cover the new materials and techniques with potential for use intra-orally or extra-o

• Sommario/riassunto: The emigrant ship William and Mary departed from Liverpool with 208 British, Irish, and Dutch emigrants in early 1853. Captained by young American Timothy Stinson, the vessel was sailing for New Orleans when the ship wrecked in the Bahamas in mysterious circumstances. Instead of grounding the ship on a nearby shore or building rafts for the passengers, Stinson and the majority of his crew sneaked away in lifeboats - murdering at least two of the emigrants with a hatchet as they did so - and reported the ship sunk with all on board lost. But the passengers kept the ship afloat and two days later were rescued by heroic wreckers as the ship went down. Now, over 160 years on, the tale of the two murdered in Bahamian waters and the hundreds who escaped thanks to kindly wreckers can finally be told. Stinson is no longer getting away with murder.

• Sommario/riassunto: Tracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree. It explores a series of broad but linked themes, providing for the first time a detailed and coherent view of the taxa of the early monocot lineages, how they diversified and their importance in monocots as a whole. Featuring contributions from leaders in the field, the chapters trace the evolution of the monocots from largely aquatic ancestors. Topics covered include the rapidly advancing field of monocot fossils, aquatic adaptations in pollen and anther structure and pollination strategies and floral developmental morphology. The book also presents a new plastid sequence analysis of early monocots and a review of monocot phylogeny as a whole, placing in an evolutionary context a plant group of major ecological, economic and horticultural importance.
