| definition of buffer in biology: Watershed Management for Potable Water Supply National Research Council, Commission on Geosciences, Environment, and Resources, Water Science and Technology Board, Committee to Review the New York City Watershed Management Strategy, 2000-02-17 In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading. |

| definition of buffer in biology: Ionic Equilibrium James N. Butler, 1998-04-13 A celebrated classic in the field updated and expanded to includethe latest computerized calculation techniques In 1964, James N. Butler published a book in which he presentedsome simple graphical methods of performing acid-base, solubility,and complex formation equilibrium calculations. Today, both thebook and these methods have become standard for generations ofstudents and professionals in fields ranging from environmentalscience to analytical chemistry. Named a Citation Classic by theScience Citation Index in 1990, the book, Ionic Equilibrium,continues to be one of the most widely used texts on the subject.So why tamper with near-perfection by attempting a revision of thatclassic? The reason is simple-- the recent rapid development andwide availability of personal computers. In the revised Ionic Equilibrium, Dr. Butler updates his 1964 workby abandoning the slide rule and graph paper for the PCspreadsheet. He also expands the original coverage with extensivematerial on basic principles and recent research. The first part of Ionic Equilibrium is devoted to the fundamentalsof acid-base, solubility, and complex formation equilibria. In thesecond part, the author discusses oxidation-reduction equilibria,develops the principles of carbon dioxide equilibria, presents casestudies demonstrating the ways in which carbon dioxide equilibriaare used in physiology and oceanography, and explores thepossibility of a pH scale for brines. The concluding chapter,written by David R. Cogley, gives examples of general computerprograms that are capable of performing equilibrium calculations onsystems of many components. Replete with real-world examples, details of importantcalculations, and practical problems, Ionic Equilibrium is an idealcourse text for students of environmental chemistry, engineering,or health; analytical chemistry; oceanography; geochemistry;biochemistry; physical chemistry; and clinical chemistry. It isalso a valuable working resource for professionals in those fieldsas well as industrial chemists involved with solution chemistry. |
| definition of buffer in biology: Phosphate Metabolism Shaul Massry, 2013-11-21 We present to our readers the proceedings of the Second International Workshop on Phosphate. A short account of the history of the effort led to the Phosphate Workshops is appro priate and can be of interest to the reader. The idea for Phosphate Workshops was born in the early days of November, 1974. One of us (S. G. M. ) suggested the thought to a group of scientists gathered for a luncheon in one of the attrac tive small restaurants in Weisbaden, Germany. The purpose of the workshop was to bring together interested scientists to discuss the newer developments and the recent advances in the field of phosphate metabolism and the other related minerals. An Organizing Committee made of Shaul G. Massry (USA), Louis V. Avioli (USA), Philippe Bordier (France), Herbert Fleisch (Switzerland), and Eduardo Slatopolsky (USA) was formed. The First Workshop was held in Paris during June 5-6, 1975 and was hosted by Dr. Philippe Bordier. Its proceeding was already published. The Second Workshop took place in Heidelberg during June 28-30, 1976 and was hosted by Dr. Eberhard Ritz. Both of these workshops were extremely successful scientific endeavors, and the need for them was demonstrated by the great interest they generated among the scientific community. The Or ganizing Committee, therefore, decided to continue with the tradi tion to hold additional Workshops annually or every other year. |

| definition of buffer in biology: Communities in Action National Academies of Sciences, Engineering, and Medicine, Health and Medicine Division, Board on Population Health and Public Health Practice, Committee on Community-Based Solutions to Promote Health Equity in the United States, 2017-04-27 In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome. |

| definition of buffer in biology: Determination of PH Roger Gordon Bates, 1964 In portraying the rise and fall, in eighteenth century Ireland and England, of Barry Lyndon - an adventurer-gambler, a cad and a romantic idealist - Kubrick departs from Thackeray's picaresque novel in scope and tone. The first person narrator of the novel gives way in the film to the third person who assumes a good deal of the storytelling function, adding to the sense of detachment and abstraction typical of Kubrick. The way that this film polarised the critics suggests that it may hold a key to his oeuvre. Enervating pictorialism or a stately meditation upon the trappings of cultural ritual that we call civilisation? The painterly tableaux suggest the 'otherness' of a past era - a world as alien as that of 2001 - in a way matched by few other period films. |

| definition of buffer in biology: Deep Learning Ian Goodfellow, Yoshua Bengio, Aaron Courville, 2016-11-10 An introduction to a broad range of topics in deep learning, covering mathematical and conceptual background, deep learning techniques used in industry, and research perspectives. “Written by three experts in the field, Deep Learning is the only comprehensive book on the subject.” —Elon Musk, cochair of OpenAI; cofounder and CEO of Tesla and SpaceX Deep learning is a form of machine learning that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts. Because the computer gathers knowledge from experience, there is no need for a human computer operator to formally specify all the knowledge that the computer needs. The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning. The text offers mathematical and conceptual background, covering relevant concepts in linear algebra, probability theory and information theory, numerical computation, and machine learning. It describes deep learning techniques used by practitioners in industry, including deep feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling, and practical methodology; and it surveys such applications as natural language processing, speech recognition, computer vision, online recommendation systems, bioinformatics, and videogames. Finally, the book offers research perspectives, covering such theoretical topics as linear factor models, autoencoders, representation learning, structured probabilistic models, Monte Carlo methods, the partition function, approximate inference, and deep generative models. Deep Learning can be used by undergraduate or graduate students planning careers in either industry or research, and by software engineers who want to begin using deep learning in their products or platforms. A website offers supplementary material for both readers and instructors. |

| definition of buffer in biology: Misconceptions in Chemistry Hans-Dieter Barke, Al Hazari, Sileshi Yitbarek, 2008-11-18 Over the last decades several researchers discovered that children, pupils and even young adults develop their own understanding of how nature really works. These pre-concepts concerning combustion, gases or conservation of mass are brought into lectures and teachers have to diagnose and to reflect on them for better instruction. In addition, there are ‘school-made misconceptions’ concerning equilibrium, acid-base or redox reactions which originate from inappropriate curriculum and instruction materials. The primary goal of this monograph is to help teachers at universities, colleges and schools to diagnose and ‘cure’ the pre-concepts. In case of the school-made misconceptions it will help to prevent them from the very beginning through reflective teaching. The volume includes detailed descriptions of class-room experiments and structural models to cure and to prevent these misconceptions. |

| definition of buffer in biology: Buffers for pH and Metal Ion Control D. Perrin, 2012-12-06 This book is intended as a practical manual for chemists, biologists and others whose work requires the use of pH or metal-ion buffers. Much information on buffers is scattered throughout the literature and it has been our endeavour to select data and instructions likely to be helpful in the choice of suitable buffer substances and for the preparation of appropriate solutions. For details of pH measurement and the preparation of standard acid and alkali solutions the reader is referred to a companion volume, A. Albert and E. P. Serjeant's The Determination of Ionization Constants (1971). Although the aims of the book are essentially practical, it also deals in some detail with those theoretical aspects considered most helpful to an understanding of buffer applications. We have cast our net widely to include pH buffers for particular purposes and for measurements in non-aqueous and mixed solvent systems. In recent years there has been a significant expansion in the range of available buffers, particularly for biological studies, largely in conse quence of the development of many zwiUerionic buffers by Good et al. (1966). These are described in Chapter 3. |

These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish. |
