R. P. PHARIS and D. M. REID The idea of a separate Encydopedia volume dealing with the "interrelations of plant hormones with factors in the environment of the plant, and its organs and tissues" originated with N. P. KEFFORD, and we are most appreciative of the help and advice provided by Prof. KEFFORD in the formative stages of this volume. We have thus interpreted "environment" very broadly to indude not only factors external to the plant, e. g. , gravity, light, temperature, wind, mechanieal wounding, water, organism s (induding pollen), and magnetic and electric stimuli, but internaI factors as well (e. g. , nutrients, both inorganic and photoassimilate, direction, and time). In our defi...
Oxidative Stress and Antioxidant Protection: The Science of Free Radical Biology and Disease Oxidative Stress and Antioxidant Protection begins with a historical perspective of pioneers in oxidative stress with an introductory section that explains the basic principles related to oxidative stress in biochemistry and molecular biology, demonstrating both pathways and biomarkers. This section also covers diagnostic imaging and differential diagnostics. The following section covers psychological, physiologic, pharmacologic and pathologic correlates. This section addresses inheritance, gender, nutrition, obesity, family history, behavior modification, natural herbal-botanical products, and suppl...
Agroforestry is an age old practice throughout the world, but its recognition as a science is nearly three decades old. The scientific and systematic research on tree-crop interactions, in India, started in late 1970's and got major support and impetus with the establishment of All India Coordinated Research Project (AICRP) on Agroforestry in 1983 by ICAR. Today AICRP on Agroforestry has its network through out the country. Under AICRP and through the individual efforts of State Agricultural Universities, location specific agroforestry systems has been recommended to suit agro-climatic zones, landholdings and economic status of the region. Though extensive research had been done till date, b...
The provision of optimal dialysis therapy to children requires a thorough understanding of the multi-disciplinary manner in which the pediatric patient is affected by renal insufficiency. Knowledge of the technical aspects of peritoneal dialysis, hemodialysis and continuous renal replacement therapy must be complemented by attention to issues such as anemia, renal osteodystrophy, hypertension, growth, cognitive development, nutrition, nursing care and the psychosocial adaptation of the child and family to chronic disease. The inaugural edition of Pediatric Dialysis provides a comprehensive review of these and other related topics with a singular emphasis on the unique aspects of their application to children. With authoritative, clinically relevant, well-referenced chapters written by a host of recognized international experts who emphasize key aspects of contemporary management, Pediatric Dialysis has been designed to serve as a primary resource to all clinicians involved in the care of the pediatric dialysis patient.
Temperate Horticulture Is A Very Important Component Of Horticulture As It Is Only Confined To The Hilly Regions Of A Country. For Fruit Crops, It Represents A Group, Which Is Physiologically Diverse From The Sub-Tropical And Tropical Fruit Crops Grown In Other Regions. For Vegetables And Floriculture It Has Immense Potential For The Keeping The Nation Well Supplied With Off-Season And Exotic Vegetables And Flowers All The Year Round.
What algorithms are tractable depends on the speed of the processor. Given the speed of digital computers, polynomial algorithms are considered tractable. But, a human can take several seconds to make one binary comparison between two pens. Given this slow speed, sublinear algorithms are considered tractable for an unaided human and this defines Simon's concept of bounded rationality.Humans make simplifications to solve the intractable consumer optimization problem. Consumers search for goods and services item-by-item, which greatly reduces the number of alternatives to consider. In addition, consumers have operators that can process a set in a single operation. Also, consumers budget by inc...
Rhizosphere biology is approaching a century of investigations wherein growth-promoting rhizomicroorganisms (PGPR) have attracted special attention for their ability to enhance productivity, profitability and sustainability at a time when food security and rural livelihood are a key priority. Bio-inputs - either directly in the form of microbes or their by-products - are gaining tremendous momentum and harnessing the potential of agriculturally important microorganisms could help in providing low-cost and environmentally safe technologies to farmers. One approach to such biologically-based strategies is the use of naturally occurring products such as PGPR. Written by an international team of experts, this book considers new concepts and global issues in biopesticide research and evaluates the implications for sustainable productivity. It is an invaluable resource for researchers in applied agricultural biotechnology, microbiology and soil science, and also for industry personnel in these areas.
