Download or read book Emissão de C-CO2 em amostras de latossolo tratadas com lodos de esgoto written by RITA CARLA BOEIRA Boeira and published by . This book was released on 2009 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lodos de esgoto possuem alto teor de carbono orgânico, porém, há um expressivo consumo de matéria orgânica logo após sua aplicação no solo, até que seja alcançado novo equilíbrio da relação C/N. Neste trabalho, apresentam- se resultados referentes à decomposição da fração orgânica de dois lodos de esgoto anaeróbios, provenientes das Estações de Tratamento de Esgoto de Franca/SP (esgoto doméstico) e de Barueri/SP (esgoto urbanoindustrial). Os tratamentos estudados foram de 1, 2, 4 e 8 vezes a aplicação da dose recomendada, com base no teor de N, de dois lodos de esgoto, as quais foram equivalentes à aplicação, numa camada de 0-20 cm de solo, de 3, 6, 12 e 24 Mg ha-1 (Franca) e 8, 16, 32 e 64 Mg ha-1 (Barueri). Avaliou-se o efeito dos tratamentos sobre a emissão de carbono na forma de CO2, em câmaras sem circulação forçada de ar, após 57 dias de incubação de misturas de amostras de um Latossolo Vermelho distroférrico com as doses dos lodos de esgoto. O padrão de emissão de C-CO2 foi semelhante nos dois tipos de lodos de esgoto. Houve aumento da liberação de C-CO2 com o aumento das doses dos dois lodos de esgoto. A taxa respiratória foi maior no início da incubação, observando-se 50% ou mais da decomposição total da matéria orgânica dos lodos de esgoto nos primeiros 15 dias. A biodecomposição estimada da matéria orgânica aplicada ao solo via lodos de esgoto foi de 15%.
Book Synopsis Caracterizacao da materia organica nos perfis de latossolo do Distrito Federal by : E. J. Corazza
Download or read book Caracterizacao da materia organica nos perfis de latossolo do Distrito Federal written by E. J. Corazza and published by . This book was released on 1997 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: O presente estudo teve como objetivo verificar o efeito dos seis sistemas de manejo: plantio direto (PD), preparo com arado de discos (AD) e grade pesada (GP), pastagem cultivada (PA), reflorestamento de eucalipto (EU) e cerrado virgem (CE), sobre a distribuicao e acumulacao do carbono organico (C) e nitrogenio (N) no perfil de latossolo vermelho-escuro; a comparacao dos estoques de C em relacao ao CE foi utilizada para analisar o comportamento do solo como fonte ou dreno de CO2 da atmosfera. Estudou-se tambem o efeito dos sistemas de manejo sobre conteudo de carboidratos (CHT) e seus componentes, os carboidratos celulosicos (CHC) e nao celulosicos (CNC), diretamente relacionados com os processos de agregacao. Por ultimo, foi estudado a distribuicao do C e do N nas fracoes granulometricas (212-2000, 53-212, 20-53, 2-20 e 0-2 um), atraves do processo de fracionamento fisico com resina, para melhor entendimento da dinamica do C e N entre os diversos sistemas de manejo. Em relacao ao sistema natural (CE), verificou-se que a acumulacao de C foi maior nos sistemas sem perturbacao do solo (PD, PA, EU) e menor nos sistemas perturbados (AD e GP), sendo que, os solos sob PD, PA e EU, funcionaram como dreno e os solos sob GP e AD como fonte de CO2. A relacao C/N do solo foi praticamente a mesma em todos os sistemas de manejo, variando de 10,6 em GP a 12,6 em PD e EU. De mode geral, a acumulacao dos carboidratos (CHT) seguiu a do C para os diferentes sistemas e correspondeu a 43,5% +- 4,5 do C, sendo que, dentro de CHT a fracao CNC foi de 4,4 a 6,4 vezes maior do que a CHC. Em todos os sistemas a acumulacao de C na fracao argila (0-2um) variou de 66 a 78% do C, no PD a CE, respectivamente e as diferencas entre as quantidades acumuladas na fracao argila entre os sistemas PD, AD e GP sugerem que o manejo do solo influenciou a acumulacao do C naquela fracao. A relacao C/N nas classes de particulas, decresceu da maior para a menor fracao granulometrica, com taxa de queda mais intensa nos sistemas perenes do nos anuais.

Book Synopsis Dams and Development by : Sanjeev Khagram
Download or read book Dams and Development written by Sanjeev Khagram and published by Cornell University Press. This book was released on 2018-08-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big dams built for irrigation, power, water supply, and other purposes were among the most potent symbols of economic development for much of the twentieth century. Of late they have become a lightning rod for challenges to this vision of development as something planned by elites with scant regard for environmental and social consequences—especially for the populations that are displaced as their homelands are flooded. In this book, Sanjeev Khagram traces changes in our ideas of what constitutes appropriate development through the shifting transnational dynamics of big dam construction. Khagram tells the story of a growing, but contentious, world society that features novel and increasingly efficacious norms of appropriate behavior in such areas as human rights and environmental protection. The transnational coalitions and networks led by nongovernmental groups that espouse such norms may seem weak in comparison with states, corporations, and such international agencies as the World Bank. Yet they became progressively more effective at altering the policies and practices of these historically more powerful actors and organizations from the 1970s on. Khagram develops these claims in a detailed ethnographic account of the transnational struggles around the Narmada River Valley Dam Projects in central India, a huge complex of thirty large and more than three thousand small dams. He offers further substantiation through a comparative historical analysis of the political economy of big dam projects in India, Brazil, South Africa, and China as well as by examining the changing behavior of international agencies and global companies. The author concludes with a discussion of the World Commission on Dams, an innovative attempt in the late 1990s to generate new norms among conflicting stakeholders.

Book Synopsis Teacher Education to Enhance Diversity in STEM by : A. Anthony Ash II
Download or read book Teacher Education to Enhance Diversity in STEM written by A. Anthony Ash II and published by Routledge. This book was released on 2020-12-29 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing underlying issues in science education and teacher training, which contribute to continued underrepresentation of racial and ethnic minority students in STEM and STEAM subjects and careers, this timely volume illustrates how a critical postmodern science pedagogy (CPSP) can be used effectively to raise awareness of diversity issues amongst preservice teachers. Using a case study design consisting of class observations, interviews, content analysis, questionnaires, and instructional interventions in preservice teacher training, the volume bridges science and multicultural education and investigates how curricular development and teacher preparation can be used to ensure that science education itself promotes diversity within STEM, and throughout education. Chapters also examine the intersections of science education and science literacy for both students and teachers and, in doing so, promote the importance of positive and accurate representation of diversity within science and research discourse. The book attempts to raise awareness regarding the need for meaningful curricular reform that creates real opportunities to address historical and scientific misinformation, while increasing diversity and inclusion in schools and society. This important text will be of interest to postgraduate students, researchers, scholars, and preservice teachers in the fields of science and mathematics education, STEM, multicultural education, teacher education, urban education, and the sociology of education.
Book Synopsis Soil Quality for Crop Production and Ecosystem Health by : E.G. Gregorich
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Book Synopsis Sampling for Analytical Purposes by : Pierre Gy
Download or read book Sampling for Analytical Purposes written by Pierre Gy and published by John Wiley & Sons. This book was released on 1998-06-29 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Gy, a pioneer in every sense of the word, has spent 50 years studying the best way to take a truly representative sample. His greatest achievement perhaps has been to introduce science into the black art of sampling. The now famous and widely used formula bearing his name means that sampling is no longer a lottery but an essential analytical tool. This very readable and practical book, written by Pierre Gy himself, is the first simple guide to Pierre Gy s method to be translated into English. Although Dr Gy s formula was originally developed for the sampling of solid material in mines, etc., the theoretical arguments are equally valid for the sampling of liquids and multi-phase media. This book is as interesting as a historical perspective as it is useful for the practising modern day analyst.
