X-rays for Archaeology
This book offers physicists, art historians, archaeologists, curators, and conservators a detailed overview via contributions written by leading scientists in the field. The book contains scientific data, i.e. in situ measurement data taken with portable XRF and XRD, and fine data taken with accelerating ion beams and synchrotron radiations, together with their explanations. Results obtained by traditional scientific methods are also reviewed. The broad data collection spans experimental data taken both from monuments in the field and exhibits in museums.Also included are data from glazes, ancient gold and silver coins, gold jewelleries, gold alloys, corroded metals, gemstones (ruby, emerald and garnet), painting pigments, pottery, bronze, obsidian, stucco, turquoise, and so on.
Re-Centring the City : Global Mutations of Socialist Modernity
What is the role of monumentality, verticality and centrality in the twenty-first century? Are palaces, skyscrapers and grand urban ensembles obsolete relics of twentieth-century modernity, inexorably giving way to a more humble and sustainable de-centred urban age? Or do the aesthetics and politics of pomp and grandiosity rather linger and even prosper in the cities of today and tomorrow? Re-Centring the City zooms in on these questions, taking as its point of departure the experience of Eurasian socialist cities, where twentieth-century high modernity arguably saw its most radical and furthest-reaching realisation.
Comets : Nature, Dynamics, Origin, and their Cosmogonical Relevance
The book covers the most recent ideas about the nature and dynamics of comets, including a thorough discussion on Oort cloud dynamics which has not received due attention in other books on the subject. It also discusses the most relevant aspects of the physics and chemistry of comet nuclei, highlighting their importance as relics of the protoplanetary disk and, perhaps, as carriers of water and organics that permitted the development of life on Earth. The book contains several tables with useful data, and an ample bibliography covering the most recent work as well as some historical key contributions to the subject. It may be suitable as a textbook for graduate students with some basic knowledge of celestial mechanics and astrophysics, as well as a consult book for comet researchers, or researchers from other related fields willing to start working on comets, or get an updated view of the subject.
Biogeography and Ecology of Bulgaria
The book includes 22 chapters by 28 authors united by the single theme: biogeography and ecology of Bulgaria. From the single-celled organisms in the Black Sea sand to the endemic cave crustaceans, from the mountain glacial relict insects to the most diverse bird fauna in Europe, the unique fauna of Bulgaria has been a subject of study of mostly Bulgarian zoologists for more than a century. This is the first monograph in English broadly addressing all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues are addressed by the experts on each group.
Biodiversity of angola : Science & conservation : A modern synthesis
The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems.
