This book was released on 1978 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A lake restoration project involving surface and hypolim-netic application of 936 metric tons of liquid aluminum sulfate (alum) was carried out on Medical Lake, Washington in the summer of 1977. Previous investigation has shown that the eutrophic condition of the lake is primarily the result of internal phosphorus cycling (Bauman and Soltero, In press). Goals of the restoration project were to disrupt the phosphorus cycling and reduce phosphorus concentrations, to reduce phytoplankton production and eliminate blue-green algae blooms, to reduce ammonia concentrations and improve dissolved oxygen levels in the hypolimnion, and to improve water clarity. Preliminary results indicate that mean concentrations of total and total soluble phosphate in the water column just after spring overturn in 1978 were approximately 20 percent of those concentrations existing in the spring of 1977. Orthophosphate concentrations at spring overturn in 1978 have also been reduced to approximately 5 percent of spring 1977 levels. Water clarity improved markedly during alum application due to removal of algal cells and particulate matter by the aluminum hydroxide floc formed when alum was added. Following treatment, reduced phytoplankton standing crops as measured by cell volume and chlorophyll a concentrations also contributed to increased water clarity. A shift in the species composition of the phytoplankton community occurred. A community dominated by Cyanophyceae existed before treatment while a more diverse community of Chlorophyceae, cryptophyceae, and Chrysophyceae existed tollowing treatment. The nutrient limiting to phytoplankton growth changed from nitrogen to phosphorus following treatment as indicated by algal assay. Yields of Selenastrum capricornutum Printz in the controls also suggested that the potential for algal growth in Medical Lake was high prior to alum treatment but only moderate following treatment"--Document.

Download or read book The Effect of Decreased Phosphorus Loading on the Phytoplankton Dynamics of Eutrophic Long Lake Washington written by Gwen Pebles Burr and published by . This book was released on 1979 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Previous investigations of eutrophic Long Lake, Washington have shown the major source of algal nutrients to be the city of Spokane's primary sewage treatment effluent. Excess nutrients have promoted large algal standing crops that ultimately decomposed creating extensive hypolimnetic anoxia. To address the problem of excess nutrient loading, an advanced wastewater treatment facility was built by the city of Spokane to remove at least 85 percent of the phosphorus from municipal wastewater. The facility began operation 22 August 1977 and phosphorus removal was initiated 15 December 1977. This investigation has revealed an 80 percent decline in orthophosphate concentrations throughout the reservoir since the initiation of advance wastewater treatment. Orthophosphate concentrations at spring overturn (0.02 mg 1−1) were 20 percent of 1977 spring concentrations. Overall hypolimnetic anoxia has declined by 75 percent. Phytoplankton species composition and seasonal succession showed little change. Although decreased phytoplankton biovolume was exhibited early in the 1978 growing season as a result of decreased nutrient loading to the reservoir, an overall increase was observed due to an isolated bloom of Microcystis aeruginosa Kutz. in September. This resulted in a shift in class dominance from the Bacillariophyceae, seen in all previous years of study, to the Cyanophyceae in 1978. It appeared that a change in nutrient limitation from nitrogen to phosphorus, as determined by algal assay, and decreased heavy metal toxicityto the test alga, Selenastrum capricornutum, may be in part responsible for the predominance of M. aeruginosa. Mean chlorophyll aö concentrations and primary productivity were not distorted by the impact of the M. aeruginosa bloom. Mean annual chlorophyll concentrations have declined significantly from 14.12 mg m−3 in 1977 to 8.79 mg m−3 in 1978. The correlation between chlorophyll aö concentration and phytoplankton biovolume remained positive in spite of the high biovolume observed in September of 1978. Primary productivity also showed a significant decline from 1.45 g C m−2 day−1 in 1977 to 0.88 g C m−2 day−1 in 1978. Fluctuations in phytoplankton standing crop during 1978 appeared to be affected by zooplankton grazing as well as nutrient concentrations. A good correlation existed between decreased phosphorus loading and mean annual chlorophyll aö concentration. This indicated that phosphorus loading gave a reasonable estimate of chlorophyll aö standing crop. Decreases in phosphorus loading, chlorophyll aö concentrations, primary productivity, orthophosphate concentrations and hypolimnetic anoxia indicate the reversion of eutrophic Long Lake, Washington to more mesotrophic conditions"--Document.

Available in PDF, EPUB and Kindle. Book excerpt: For several years, researchers have been reporting the effects of microwave radiation/heating on both the structure and function of DNA, RNA and proteins. For the most part, favourable accelerated biological functions are observed as microwave induced heating occurs, but other not-so favourable effects are also observed, such as denaturation, fragmentation and the so called and ill-explained, non-thermal microwave effects. This volume, the first of its kind, brings researchers together from around the world to discuss their current findings and thinking on the effects of Microwaves on Biological systems, particularly DNA, RNA and proteins, in the form of contributed edited chapters.
Download or read book Waste Biorefineries Future Energy Green Products and Waste Treatment written by Mohammad Rehan and published by Frontiers Media SA. This book was released on 2019-09-24 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy recovery from waste resources holds a significant role in the sustainable waste management hierarchy to support the concept of circular economies and to mitigate the challenges of waste originated problems of sanitation, environment, and public health. Today, waste disposal to landfills is the most widely used methodology, particularly in developing countries, because of limited budgets and lack of efficient infrastructure and facilities to maintain efficient and practical global standards. As a consequence, the dump-sites or non-sanitary landfills have become the significant sources of greenhouse gases emissions, soil and water contamination, unpleasant odors, leachate, and disease spreading vectors, flies, and rodents. However, waste can be utilized to produce a range of potential products such as energy, fuels and value-added products under waste biorefineries. A holistic and quantitative view, such as waste biorefinery, on waste management must be linked to the actual country, taking into account its socio-economic situation, local waste sources, and composition, as well as the available markets for the recovered energy and products. Therefore, it is critical to understand that solutions cannot be just copied from one region to the others. In fact, all waste handling, transportation, and treatment can represent a burden to the cities’ environment and macro and micro economics, except for the benefits obtained from recovered materials and energy. Equally significant is a clear and quantitative understanding of the industrial, and public potential of utilizing recovered materials and energy in the markets as these can be reached without exacerbating the environmental issues using excessive transport. The book explores new advancements and discoveries on the development of emerging waste-to-energy technologies, practical implementation, and lessons learned from sustainable wastemanagement practices under waste biorefinery concept, which will accelerate the growth of circular economies in the world. The articles presented in this book have been written by expert researchers and academics working in institutions at different countries across the world including Germany, Greece, Japan, South Korea, China, Saudi Arabia, Pakistan, Indonesia, Malaysia, Iran, and India. The research articles have been arranged into three main subject categories; 1) Resource recovery from waste, 2) Waste to energy technologies and 3) Waste biorefineries. This book will serve as an important resource for research students, academics, industry, policy makers, and government agencies working in the field of integrated waste management, energy and resource recovery, waste to energy technologies, waste biorefineries etc. The editorial team of this book is very grateful to all the authors for their excellent contributions and making the book successful.

Download or read book Environmental Concerns and Sustainable Development written by Vertika Shukla and published by Springer. This book was released on 2019-07-03 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prevailing global environmental crisis is primarily because of non-standardized parameters for environmental regulation. Unplanned expansion of economic activities, consideration for environmental conservation and several associated problems are emerging due to degradation in quality of ambient environment such as clean air, safe drinking water and quality of food, particularly in developing nations. Due to poor/casual execution of EIA protocol, newly developing countries are preferred destination for establishing pollution emitting industries, which results in degradation and depletion of natural resources. Lack of environmental policy intervention is another major attraction for establishing such industries in these nations. In order to ensure sustainable development, the highest priority issues include the monitoring and eradication of environmental problems which arise due to economic development. Initiation of any form of economic development primarily results in loss of forests and thus biodiversity, followed by deterioration in quality of air and contamination of natural resources. The worst impact of non-standardized economic development is the contamination of air, water and soil. Sustainable development ensures responsible interface with the environment to minimize the depletion or degradation of natural resources and ensure long term environmental quality. It involves integrated approaches in understanding the importance of environmental management systems and policy inventions leading to improved environmental performance. The present book is proposed to address the environmental concerns associated with economic development and approaches involved to attain sustainable economic development, which include monitoring of the quality of air, deforestation, quality of water resources, soil erosion and degradation of the natural environment.

Download or read book Eating Architecture written by Jamie Horwitz and published by MIT Press. This book was released on 2006-02-17 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: A highly original collection of essays that explore the relationship between food and architecture—the preparation of meals and the production of space. The contributors to this highly original collection of essays explore the relationship between food and architecture, asking what can be learned by examining the (often metaphorical) intersection of the preparation of meals and the production of space. In a culture that includes the Food Channel and the knife-juggling chefs of Benihana, food has become not only an obsession but an alternative art form. The nineteen essays and "Gallery of Recipes" in Eating Architecture seize this moment to investigate how art and architecture engage issues of identity, ideology, conviviality, memory, and loss that cookery evokes. This is a book for all those who opt for the "combination platter" of cultural inquiry as well as for the readers of M. F. K. Fisher and Ruth Reichl. The essays are organized into four sections that lead the reader from the landscape to the kitchen, the table, and finally the mouth. The essays in "Place Settings" examine the relationships between food and location that arise in culinary colonialism and the global economy of tourism. "Philosophy in the Kitchen" traces the routines that create a site for aesthetic experimentation, including an examination of gingerbread houses as art, food, and architectural space. The essays in "Table Rules" consider the spatial and performative aspects of eating and the ways in which shared meals are among the most perishable and preserved cultural artifacts. Finally, "Embodied Taste" considers the sensual apprehension of food and what it means to consume a work of art. The "Gallery of Recipes" contains images by contemporary architects on the subject of eating architecture.
