There is a paucity of information on the dynamics of Ascorbic Acid (AA) turnover in relation to germination, metabolism, growth, differentiation and development of a plant and in those undergoing stress of various types. in presowing treatment of seeds etc. The turnover of AA plays an important role during the juvenile phase of growth of a plant and has a significant bearing on its subsequent growth, development and maturation. The beneficial effect of presowing treatment of seed with Ascorbic Acid (AA) + H2 O highlights the validity of the AA-nucleic acid 2 protein metabolism concept of growth and development of plan ts. During the course of the last 30 years, work has been undertaken by the author and his collaborators on the meta bolic drifts of regulatory substances during juvenile, vegetative, reproductive and senescent phases. The most important of these growth regulatory substances was found to be Ascorbic Acid. The dynamiC role of AA turnover is revealed by its control of rates of metabolic processes as well as those of enzymic reactions which paves the way to "New Genetics".
This well-illustrated textbook is the first comprehensive and authoritative source of information on minimally invasive lateral access spine surgery. It covers all aspects of the subject, including patient selection, approach and monitoring techniques, soft tissue management, application in a variety of pathologies, technical nuances, and the prevention and management of complications. In addition, current controversies in the field are discussed and the biomechanics of lateral spinal reconstruction, the physiologic benefits, and cost implications are explained. As use of the lateral approach in spinal surgery has become more popular, so its diversity and complexity have increased. Nevertheless, publications devoted entirely to the technique are lacking, and Lateral Access Minimally Invasive Spine Surgery is designed to fill this vacuum. Written by the world’s experts on the topic, it will be an excellent resource for both beginning and experienced surgeons.

Edited by Drs. Todd J. Albert and Thomas A. Zdeblick, this fully revised edition presents the preferred techniques of surgical masters, illustrated with sequential, surgeon’s-eye view intraoperative photographs, as well as superb drawings by noted medical illustrators. New contributing authors and new and rewritten chapters keep you fully up to date with recent changes in the field.
This book explores the use of nanomaterials as diesel fuel additives. It extensively reviews the diesel engine characteristics and the most frequently used nanomaterials and nanofuels and discusses the practical issues regarding the viability of nanomaterials as fuel additives from technical, environmental, and human health viewpoints. Special attention is focused on questions related to the short-term use of nanomaterials in diesel engines, such as: · What are the most important nanomaterial activities in diesel engines? · What happens to nanomaterials at various stages, from the fuel tank to exhaust? · What are the effects of nanofuel usage on diesel engine characteristics? and · What are the effects of nanomaterials on diesel engine parts and systems? Given its scope, this book is a valuable resource for researchers and engineers in environmental science, mechanical engineering, and chemical engineering fields, as well as for advanced undergraduate and postgraduate students.
Soil is not only a fundamental source for all living organisms but also impacts non-living factors (water, air, minerals, etc.) making it an invaluable and finite resource. The importance of soil expands from agronomy through to industrialization, thus, it is crucial to understand the impact of human activity on soil quality. To address several global issues related to pollution, food security, and health, the United Nations promotes the Sustainable Development Goals (SDGs) with targets to ‘save soil’ by minimizing nutrient loss and pollution load from the soil. Due to increasing anthropogenic pollution load, many soil pollution control measures are failing, therefore, new technologies a...
