Buch. Condición: Neu. Neuware - In the 50 years since the first volume of Progress in Optics was published, optics has become one of the most dynamic fields of science. The volumes in this series that have appeared up to now contain more than 300 review articles by distinguished research workers, which have become permanent records for many important developments, helping optical scientists and optical engineers stay abreast of their fields. Comprehensive, in-depth reviews Edited by the leading authority in the field. …

Buch. Condición: Neu. Neuware - New developments in mass spectrometry have allowed routine identification and lowered limits of detection at levels only imagined a decade ago. Thousands of contaminants and residues in the food supply and the environment are now being reported. Between 2005 and 2010, more than 5,000 publications covering TOF-MS and environmental and food analysis were published, showing the importance of the technique in these applications. This book covers the basic principles of method development in GC- and LC-TOF-MS as well as the main operational parameters related to TOF-MS. The second part focuses on the relevant environmental applications, including quality control aspects as well as data collection. The third part is devoted to relevant applications in food analysis, including validation procedures for screening analysis as well as relevant databases. …

Buch. Condición: Neu. Neuware - Innovation and creativity are two of the key characteristics that distinguish cultural transmission from biological transmission. This book explores a number of questions concerning the nature and timing of the origins of human creativity. What were the driving factors in the development of new technologies What caused the stasis in stone tool technological innovation in the Early Pleistocene Were there specific regions and episodes of enhanced technological development, or did it occur at a steady pace where ancestral humans lived The authors are archaeologists who address these questions, armed with data from ancient artefacts such as shell beads used as jewelry, primitive musical instruments, and sophisticated techniques required to fashion certain kinds of stone into tools. Providing 'state of art' discussions that step back from the usual archaeological publications that focus mainly on individual site discoveries, this book presents the full picture on how and why creativity in Middle to Late Pleistocene archeology/anthropology evolved.…
