Application Of Colloidal Gas Aphron Suspensions Produced From Sapindus Mukorossi For Arsenic Removal From Contaminated Soil, Soumyadeep Mukhopadhyay Dr 2015 SelectedWorks

Application Of Colloidal Gas Aphron Suspensions Produced From Sapindus Mukorossi For Arsenic Removal From Contaminated Soil, Soumyadeep Mukhopadhyay Dr

Soumyadeep Mukhopadhyay Dr

Colloidal gas aphron dispersions (CGAs) can be described as a system of microbubbles suspended homogenously in a liquid matrix. This work examines the performance of CGAs in comparison to surfactant solutions for washing low levels of arsenic from an iron rich soil. Sodium Dodecyl Sulfate (SDS) and saponin, a biodegradable surfactant, obtained from Sapindus mukorossi or soapnut fruit were used for generating CGAs and solutions for soil washing. Column washing experiments were performed in down-flow and up flow modes at a soil pH of 5 and 6 using varying concentration of SDS and soapnut solutions as well as CGAs. Soapnut ...


Trophic Status Of Conesus Lake 2014: Long-Term Trends In Lake Chemistry And The Plankton Community, Joseph C. Makarewicz, Theodore W. Lewis 2014 The College at Brockport: State University of New York

Trophic Status Of Conesus Lake 2014: Long-Term Trends In Lake Chemistry And The Plankton Community, Joseph C. Makarewicz, Theodore W. Lewis

Technical Reports

Conesus Lake, considered a eutrophic lake in the late 1960s (Mills, 1975) and one of the smaller of the Finger Lakes of western New York, is used for recreation and fishing and is a source of municipal water for several local communities. The shoreline area is densely populated with residences, primarily year-round homes. The upstream area is a mixture of agricultural land and mixed deciduous hardwood forests encompassing an area of 16,714 ha. In 1999 about half of the entire land use within the Conesus Lake watershed was and continues to be in agriculture. Much of the agriculture (~70 ...


No More Hidden Secrets: Human Rights Violations And Remote Sensing, Tommy O'Connell, Dr. Stephen Young 2014 University of South Florida

No More Hidden Secrets: Human Rights Violations And Remote Sensing, Tommy O'Connell, Dr. Stephen Young

Genocide Studies and Prevention: An International Journal

Aim: This study used both high resolution and medium resolution satellite imagery to test three semi-automated remote sensing methods, in an attempt to identify useful tools to support eye-witness testimony and reports on human rights violations. As huts are routinely burned down during attacks on a village, particularly in Sudan, the number of huts and villages burned can be used to corroborate on-the-ground reports.

Methods: Three remote sensing methods (Supervised Classification, Change Detection, and Feature Extraction) were performed on imagery from both before the attacks in February 2006 and after the attacks to examine any useful trends that could be ...


Making Water Resource Decisions More "Informationally" Efficient: Development Of A Geospatial Water Rights Decision Support System For Kittitas County, Washington, Michael Pease, Jeremy Murray 2014 University of Wisconsin Milwaukee

Making Water Resource Decisions More "Informationally" Efficient: Development Of A Geospatial Water Rights Decision Support System For Kittitas County, Washington, Michael Pease, Jeremy Murray

International Journal of Geospatial and Environmental Research

In semi-arid river basins like the Yakima River Basin in central Washington State, United States of America, water demand can exceed available supply on an annual basis. More informed decisions about water supply and current allocation have the potential to improve water management. This research created a geospatial water rights database for the Yakima River Basin. The creation of a publicly available decision support system mapping water rights can provide water managers another tool to help achieve this goal. This paper describes the creation of the Decision Support System. In addition it looks at the current utility of the system ...


Water Scarcity In The Jordan River Basin, Matthew Cook 2014 University of Minnesota Morris Digital Well

Water Scarcity In The Jordan River Basin, Matthew Cook

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

The watershed of the Jordan River stretches over four countries – Jordan, Syria, Israel, and Lebanon – and includes the region of Palestine. With the land and its resources hotly contested by all parties involved, the dwindling supply of drinking and irrigation water from viable sources has led to scrambling exploitation, leaving the river and its connected lakes in an ever-worsening state of deterioration. Increased suspended solids, presence of toxin-producing cyanobacteria, and accelerated evapotranspiration have led to a slower, shallower, murkier, and lower health quality trickle taking the place of the once-revered River Jordan (Comair et al., “Watershed Delineation” 4285; Hadas et ...


Vernal Pool: A Participatory Art Project About Place + Precipitation, Karen Abel, Jessica Marion Barr 2014 Wilfrid Laurier University

Vernal Pool: A Participatory Art Project About Place + Precipitation, Karen Abel, Jessica Marion Barr

The Goose

Produced by Karen Abel with Jessica Marion Barr, Vernal Pool is an immersive, elemental water installation created as a participatory, contemplative inquiry into our transitory interrelationships with water and landscape. From November 2013 to April 2014, 114 individuals across Canada and abroad gathered snow samples as a form of extrinsic artistic practice about place and precipitation. With the arrival of spring, the reservoir of melted snow was convened for four days at Toronto’s historic Gladstone Hotel to create Vernal Pool.


A Methodology For Near-Field Tsunami Inundation Forecasting: Application To The 2011 Tohoku Tsunami, Aditya Riadi Gusman, Yuichiro Tanioka, Breanyn MacInnes, Hiroaki Tsushima 2014 Central Washington University

A Methodology For Near-Field Tsunami Inundation Forecasting: Application To The 2011 Tohoku Tsunami, Aditya Riadi Gusman, Yuichiro Tanioka, Breanyn Macinnes, Hiroaki Tsushima

All Faculty Scholarship (COTS)

Existing tsunami early warning systems in the world can give either one or a combination of estimated tsunami arrival times, heights, or qualitative tsunami forecasts before the tsunami hits near-field coastlines. A future tsunami early warning system should be able to provide a reliable near-field tsunami inundation forecast on high-resolution topography within a short time period. Here we describe a new methodology for near-field tsunami inundation forecasting. In this method, a precomputed tsunami inundation and precomputed tsunami waveform database is required. After information about a tsunami source is estimated, tsunami waveforms at nearshore points can be simulated in real time ...


Trading Fat For Forests: On Palm Oil, Tropical Forest Conservation, And Rational Consumption, Cindy Isenhour 2014 The University of Maine

Trading Fat For Forests: On Palm Oil, Tropical Forest Conservation, And Rational Consumption, Cindy Isenhour

Anthropology Faculty Scholarship

The longstanding butter vs margarine debate has recently become more complex as the links between margarine, industrial palm oil plantations, and tropical deforestation are made increasingly clear. Yet despite calls for consumers to get informed and take responsibility for tropical deforestation by boycotting margarine or purchasing buttery spreads made with sustainably-sourced palm oil, research in multiple contexts demonstrates that even the most aware, engaged, and rational consumers run into significant barriers when trying to reduce their environmental impacts. This paper supplements important critiques of neoliberal conservation at the site of extraction or intended conservation (Carrier and West 2009; Igoe and ...


Potential Effects Of Changing Climate On The Physical, Chemical, And Biological Characteristics Of Alpine Lakes, Uinta Mountains, Utah, Usa, Shirley Ngai 2014 Western University

Potential Effects Of Changing Climate On The Physical, Chemical, And Biological Characteristics Of Alpine Lakes, Uinta Mountains, Utah, Usa, Shirley Ngai

University of Western Ontario - Electronic Thesis and Dissertation Repository

Relationships between climate variables, lake characteristics and diatom community composition were determined for five lakes in the Uinta Mountains, Utah (USA) from spring 2010 to autumn 2013 to provide information to help predict the effects of climate change on lake ecosystems. Surface water temperatures increased with decreasing elevation although microclimates affected this relationship. Deeper water temperatures increased or stayed the same with increasing elevation, probably due to greater transparency or convective heating. Total phosphorus (TP) and chl a concentrations decreased in the spring/summer with warmer fall/winter temperatures, and nitrates in the spring increased with increased fall/winter precipitation ...


Reply To ‘Co2 Emissions From Crop Residue-Derived Biofuels’, Adam Liska, Haishun Yang, Matthew P. Pelton, Andrew E. Suyker 2014 University of Nebraska - Lincoln

Reply To ‘Co2 Emissions From Crop Residue-Derived Biofuels’, Adam Liska, Haishun Yang, Matthew P. Pelton, Andrew E. Suyker

Adam Liska Papers

The soil organic carbon (SOC) model that we used was parameterized with data from arable land under normal farming conditions in North America, Europe, Africa and Asia, but the equation is insensitive to changes in tillage, soil texture and moisture. The model has reasonable accuracy, however, in predicting changes in SOC, residue remaining and CO2 emissions from initial SOC, carbon inputs from residue, and daily temperature; the shoot-to-root ratio used in the geospatial simulation was 0.29 (that is, root carbon is 29% of total aboveground carbon), which did not underestimate carbon input to soil (Supplementary Figure 2 in ...


The Figure Of Bitu-Man, Paul Royster 2014 University of Nebraska - Lincoln

The Figure Of Bitu-Man, Paul Royster

Faculty Publications, UNL Libraries

The ominously imposing figure in the above illustration is “the Syncrude bird deterrent device, locally known as ‘Bitu-man’.” He stands (or stood—the original image was from the late 1970s) in the tailings pond of the Syncrude Canada Ltd. oil sands mining operation along the Athabasca River near Fort McMurray in northeastern Alberta. That operation surface mines (i.e., strip mines) bitumen-impregnated sand, processes it with hot water and steam, and discharges the liquid effluent or “tailings” into a pond covering roughly 3000 hectares (11 square miles). (Google Map coordinates: 56.9°N, -111.3° W). Residue bitumen collects on ...


The Status Of Fishes In The Missouri River, Nebraska: Lake Sturgeon (Acipenser Fulvescens), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman 2014 University of Nebraska - Lincoln

The Status Of Fishes In The Missouri River, Nebraska: Lake Sturgeon (Acipenser Fulvescens), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Lake Sturgeon (Acipenser fulvescens) occurrences in the Missouri River along Nebraska’s eastern border are historically sporadic and rare. Presently, the wild Lake Sturgeon population in this river reach may be extirpated. A Recovery Program initiated by the Missouri Department of Conservation (MDC) has stocked almost 150,000 hatchery-reared Lake Sturgeon into the lower Missouri River at several sites in Missouri. As a result, the number of Lake Sturgeon collected has increased. Since monitoring began in 2003, no Lake Sturgeon have been collected above Gavins Point Dam while 40 fish were collected downstream of Gavins Point Dam. The majority of ...


Conesus Lake Fish Stock Assessments 2001-2009, Matthew J. Sanderson 2014 The College at Brockport: State University of New York

Conesus Lake Fish Stock Assessments 2001-2009, Matthew J. Sanderson

Government Documents

Warm water fisheries assessments using standard gangs of gill nets were conducted in Conesus Lake in September of 2001, 2004, and 2009. The purpose of the surveys was to assess the fish community; the contribution of stocked fingerlings to the walleye (Sander vitreus) population; estimate population characteristics of walleye, smallmouth bass (Micropterus dolomieui), and northern pike (Esox lucius); compare fish community structure to previous surveys; and guide the development of appropriate management recommendations. From the 1990’s to the 2000’s, species dominance shifted from walleye to sunfish (Lepomis, sp.), and yellow perch (Perca flavescens) went from being a major ...
