Sounding Ground

The fundamentals of methods in nuclear geophysics and their practical applications in engineering geology, hydrology, hydrogeology, agriculture and environmental science are discussed in this book. The methods and apparatus based on absorption and scattering of gamma and neutron radiation for determination of density and soil moisture in natural conditions are presented in Chapters 2, 3, and 4. The theoretical fundamentals and installations of the penetration logging techniques where gamma, gamma-gamma and neutron logging in combination with static penetration form common complexes for engineering geology and hydrogeology exploration without boring holes are described. The developed constructions and practical use penetration logging installations for applications on land and marine shelves are described in Chapters 5, 6, 7, and 8. The physical fundamentals for the use of the natural stable and radioactive isotopes for study of the global hydrological cycle are provided. The experimental data, origin and distribution of cosmogenic and radiogenic isotopes in the oceans, atmospheric moisture, surface and underground waters are presented in Chapters 9, 10, and 11. The sources and conditions of the radioactive contamination of the natural waters are discussed in Chapters 12 and 13. This book will be of interest to scientists and researchers who use nuclear geophysics methods in engineering geology, hydrology, hydrogeology and hydrogeoecology. Lecturers, students, and postgraduates in these subjects will also find it useful.

Winner of: 2015 OCM Bocas Prize for Caribbean Literature Vladimir Lucien is a young poet with so many gifts; his poetry is intelligent, musical, gritty in observation, graceful in method. His poems contain stories of ancestors, immediate family, the history embedded in his language choices as a St Lucian writer, and heroes such as Walter Rodney, C. L. R. James, Kamau Brathwaite, and a local steelbandsman. Although never overtly political, there's an oblique and often witty politics embedded in the poems, as where observing the rise of a grandfather out of rural poverty into the style of colonial respectability, he writes of the man "who eat his farine and fish / and avocado in a civilize fight between / knife and fork and etiquette on his plate." This is a collection that is alive with its conscious tensions both in subject matter and form. There's a tension between the vision of ancestors, family, and of the poet himself as being engaged in the business of acting in the world and building on the past, and a sharp awareness of the inescapability of age's frailty, the decay of memory and of death.
