Quotations have exercised a particular fascination for humanity since the birth of recorded language and their potency in the age of the soundbite is stronger than ever. We revel in quotations, compete to know them, love them, hate them and inscribe them in books and on buildings, and this freshly revised and updated dictionary includes a wealth of new material among its 13,000 familiar, serious, outrageous, witty and thought-provoking entries.The Wordsworth Dictionary of Quotations is an essential work of reference for every writer, journalist and speech-maker, as well as being a treasure-trove for the browser and the simply curious. From the Roman poet Ovid's observation that 'Judgement of beauty can er, what with the wine and the dark' to Oscar Wilde's that 'Experience is the name everyone gives to their mistakes', there is a wide diversity of sayings to add spice to our conversation and enrich our daily lives. The book is alphabetically arranged by author and indexed by keyword for ease of use.

Do you want to know what inherited defect causes thalassaemia? Do you understand the significance of "resistance" when applied to microbiology? Can you say what a "frozen section" really is? The Dictionary of Biomedical Sciences answers all these questions and more. This informative, practical guide contains over 8000 entries that define all the basic principles of biomedical sciences, together with a wealth of other information. It reflects current practice in all aspects of biomedical science and includes variant spellings, punctuation, abbreviations, acronyms, symbols, nomenclature, prefixes and suffixes and covers the field in a concise, clear and authoritative manner.

Like it or not, abbreviations and acronyms are now an essential ingredient of everyday life. Since the first edition of The Wordsworth Dictionary of Abbreviations & Acronyms was published in mid-1997, the compilers have been diligently collecting further examples from many walks of life

Although many books have been published on various aspects of human, animal, and plant parasitology, as well as the public health problems associated with parasites, none to date has offered a comprehensive glossary for those confronted with the discipline's exceptionally extensive terminology. To meet this need requires a dedicated text that can h

This dictionary contains over 45,000 informative and easy-to-use definitions. It includes examples of modern words, grammatical information and parts of speech and guidance on pronunciation.

The perfect reference book for everyday use, it provides definitions written in clear, jargon-free language readily accessible to every level of reader.

How kindness—and other prosocial behaviors toward others—can help us live longer and healthier lives. The science is in: being good is actually good for you. In this bracingly original book, The Biology of Kindness—the first in a trilogy on the topic of daily wellness—the science of mindfulness and the findings of biology come together to show how kindness and optimism improve overall well-being in profound, organic, and demonstrable ways. Daniel Lumera, an expert in meditation and mindfulness, and Immaculata De Vivo, a preeminent researcher in molecular epidemiology, outline a revolutionary approach to health, longevity, and quality of life—and explain the scientific evidence that supports their work. Identifying five fundamental values—kindness, optimism, forgiveness, gratitude, and happiness—and describing six essential strategies for cultivating these values—relationships, nutrition, physical activity, meditation, music, and connection with nature—De Vivo and Lumera chart a practical course for pursuing a long, healthy, and happy life. Along the way they provide the scientific data that reveal the impact such behavior has on biology, particularly on telomeres, the parts of DNA that serve as biomarkers of aging. While DNA is mostly immutable, telomeres are influenced by our choices, and The Biology of Kindness offers incontrovertible evidence that what is commonly ascribed to “spiritual” well-being has a clear and direct impact on physical health, helping to buffer premature aging and decrease the incidence of chronic disease. At a time when life seems to be ruled by a desire to get “everything and immediately,” Lumera observes, there is a compelling case to be made for the discipline of devotion, dedication, and passion—for the good of the body as well as the soul.

Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.
