This book was released on 2015 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Sediment core archives provide a history of data useful for serving as a long-term monitoring reserve to evaluate chronological events of contamination to lake systems. This could be an effective tool for continual environmental management, monitoring and potential restoration efforts. This method is also very cost-effective without the addition of a water quality monitoring station on site. Taking 3 sediment cores from Punderson Lake Ohio for analysis has allowed associating variations in select metals to anthropogenic events or activities; we can determine a time frame with limited uncertainty and resolve the intensity of anthropogenic contamination to the lake starting with post World War II contamination till the present. We used sedimentation rate in conjunction with radiometric dating methods of 137Cs to establish a timeline through the cores. Applying mass depth g/cm2 (Matisoff and Whiting, 2011) and core segmentation intervals (1cm) we can remove issue of porosity and compaction. Selected trace elements (As, Cu, Mn and Pb) were studied in these sediment cores. We can parse natural crustal sources of sediment input from anthropogenic sources using a method known as enrichment factor (EF) (Feng et al., 2004). This method requires the normalization of trace metal concentration against Al into an index/dimensionless data form (Essien et al. 2009). EF index implies a severity of contamination in a sediment interval allowing for the consideration of environmental impact, status of pollution and possibly source the contamination of the select trace metal. We can then plot EF over time to obtain relative burial times of the excess trace metals. We can then make a comparison to other regional lakes to see how anthropogenic source contamination appears in other systems. We used diatoms as a biological component as they are sensitive to ecosystem/environmental changes and preserve well in buried sediment. Therefore; diatoms can be seen as responding to possible human influences that are changing the habitat or quality of the lake. We found correlations within the core showing trace element pollution related to anthropogenic activities. Primarily we can see strong signals of Pb and As in earlier portions of the core indicative of industrialization and fossil fuel burning of the time. We also see a rise in Cu enrichment at the top of the core which, is linked to CuSO4 additions to the lake. Diatoms confirm that the CuSO4 is having an impact on biotic components of the lake particularly changing their community structures. It is important to consider the benefits of this type of study. Future benefits such as building and periodically updating a data base that can be used to track a lake systems contamination levels and provide invaluable insight into remediation and site maintenance efforts.
Download or read book Water Quality Monitoring and Assessment written by Stephanie Fraser and published by . This book was released on 2020-09-08 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological, radiological, chemical and physical traits of water are known as water quality. It is a measure of the water condition related to the requirements of biotic species and to human need. The health of ecosystems, safety of human contact, and drinking water are the most common standards used to measure water quality. Water quality parameters can be categorized into human consumption, environmental water quality, and industrial and domestic use. The measurement of water quality includes the process of sample collection, chemical analysis, real-time monitoring and testing in response to natural disasters. Various environmental indicators such as physical, chemical and biological indicators are also observed and used for the monitoring of water quality. This book explores all the important aspects of water quality in the present day scenario. It elucidates new techniques and their applications in a multidisciplinary manner. It will prove to be immensely beneficial to students and researchers in this field.
Download or read book Walking to Listen written by Andrew Forsthoefel and published by Bloomsbury Publishing USA. This book was released on 2017-03-07 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: A memoir of one young man’s coming of age on a journey across America--told through the stories of the people of all ages, races, and inclinations he meets along the way. Life is fast, and I’ve found it’s easy to confuse the miraculous for the mundane, so I’m slowing down, way down, in order to give my full presence to the extraordinary that infuses each moment and resides in every one of us. At 23, Andrew Forsthoefel headed out the back door of his home in Chadds Ford, Pennsylvania, with a backpack, an audio recorder, his copies of Whitman and Rilke, and a sign that read "Walking to Listen." He had just graduated from Middlebury College and was ready to begin his adult life, but he didn’t know how. So he decided to take a cross-country quest for guidance, one where everyone he met would be his guide. In the year that followed, he faced an Appalachian winter and a Mojave summer. He met beasts inside: fear, loneliness, doubt. But he also encountered incredible kindness from strangers. Thousands shared their stories with him, sometimes confiding their prejudices, too. Often he didn’t know how to respond. How to find unity in diversity? How to stay connected, even as fear works to tear us apart? He listened for answers to these questions, and to the existential questions every human must face, and began to find that the answer might be in listening itself. Ultimately, it’s the stories of others living all along the roads of America that carry this journey and sing out in a hopeful, heartfelt book about how a life is made, and how our nation defines itself on the most human level.
Download or read book Y Origami written by David C. Morgan and published by American Mathematical Soc.. This book was released on 2017-12-06 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: When origami met the worlds of design and engineering, both fields embraced the ancient art form, using its principles and practices to discover new problems and to generate inventive solutions. This book demonstrates the potential of folding to improve the way things work, simplify how products are produced, and make possible new objects otherwise impossible. The solar collector, the felt stool, and the surgery tool have all been influenced in some way by folding paper. The example section is organized to show the folded figure next to the product prototype that was inspired by that work of origami. We have included models made from an array of materials over a range of sizes. This includes everything from a microscopic mechanism to huge solar panels designed to unfold in outer space. Most entries are at the prototype phase—meaning that physical hardware has been built to demonstrate the concept, but that the examples are not necessarily available commercially. Y Origami? also includes brief learning activities related to paper folding, such as a discussion of Euler's formula, angular measurements, and developable surfaces, along with more advanced topics. Throughout the book many diagrams and photographs illustrate the advancing concepts and methods of origami as an art form and a problem-solving strategy.
