Tropospheric ozone is a regionally distributed air pollutant that adversely affects both humans and vegetation. Surface-Level Ozone Exposures and Their Effects on Vegetation focuses on the formation, distribution, and transport of surface-level ozone; the characterization of its exposures; the mechanisms and processes involved in its deposition and uptake by plants; and its effects on the growth of crops and forest trees. State-of-the-art information is presented and the methodology for studying its effects on vegetation is critically reviewed. This background material leads to a discussion of the approaches for developing an air quality standard that will provide protection from the adverse effects of ozone, as well as suggestions for future research directions. Researchers and professionals in the utility industry, oil industry, and government environmental agencies; university instructors; and students will find that this book is filled with information that can be used on a daily basis in their work and studies.

Early Flowers And Angiosperm Evolution

The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

This definitive reference book, designed for use at all levels, explains both current and historical methods of naming chemical compounds. It explains and provides a rationale for the methods used in chemical nomenclature. Terms are defined, and numerous examples add clarification. The 16 chapters proceed from elementary substances to nonstoichiometric and molecular compounds, gradually building a coherent system for communicating information about chemical entities. Among the specific topics discussed are homoatomic and heteroatomic species, coordination compounds, polymeric compounds, nonmetal hydrides and their derivatives, polyboron hydrides, chain and ring compounds, organometallic compounds, nonstoichiometric species, isotopically modified species, and stereoisomers.

Ultrasound technology is enabling anesthesiologists to perform regional anesthetic procedures with greater confidence in accuracy and precision. With improvements in visualizing neural anatomy and needle movement, ultrasound guidance improves patient safety and operating room efficiency. This book offers a detailed, stepwise approach to this technique, identifying pearls and pitfalls to ensure success. Topics are organized into four chapters. The first chapter provides the basic principles behind ultrasound guided regional anesthesia, setting a strong context for the rest of the book. The last three cover the nerve blocks: upper extremity, lower extremity, and chest, trunk and spine. Each nerve block is comprehensively explained, divided up by introduction, anatomy, clinical applications, technique, alternate techniques, complications, and pearls. This new edition includes discussions of 6 new blocks: the suprascapular block, axillary nerve block for shoulder surgery, fascia iliaca block, lateral femoral cutaneous block, and the adductor canal block. This edition also contains over 40 new procedural and imaging figures, an appendix on what blocks to perform for specific surgeries, and new information on choice of local anesthetic agent, types of catheters and practical ultrasound physics to help improve scanning. Ultrasound Guided Regional Anesthesia provides authoritative, in-depth coverage of ultrasound guided regional anesthesia for the anesthesiologist beginning to use ultrasound and makes a great reference for the more seasoned physician.

De Agricultura

The introduction places the man and his work in context and discusses specific problems of textural arrangement and organization and agricultural practice. There are several drawings to aid appreciation of Cato’s descriptions of buildings and equipment. A book of instruction about the cultivation of vines, olives and fruit, the management of slaves and contract labour, the rituals consequent on ownership and even cookery for humans and the pharmacy. Because of its date, the 2nd century BC, it is a particularly important resource for students of Latin and of early Roman society.
