Drinking Water Optimum Supply System (Dwoss) Through The Application Of Advanced Technologies, Praveen Jha Dr
Drinking Water Optimum Supply System (Dwoss) Through The Application Of Advanced Technologies, Praveen Jha Dr
Praveen Jha Dr
Paradigm shift in the approach for planning regarding supply of drinking water is mandatory since the current DPRs are unscientific and expensive. Planning for an optimum Drinking Water Supply System (ODWSS) that includes - optimization of Water Source Point (WSP), Water Treatment System (WTS), Water Storage Systems (WSSs), Water Distribution Points (WDP) and Water Supply Network (WSN); scientific estimation of long term demand of drinking water; minimization of physical and financial resources required for the plan implementation; water conservation and sanitation – could be done by applying several state-of-art geo-spatial programs developed by the author. Three programs - Multi-Algorithm Automation …

The presentation is devoted to the development of the new catalytic process for oxidation of SO2 to SO3 on the base of the novel Pt-containing catalyst with Zr-Si fiber-glass support. It was demonstrated that such catalyst reveals excellent low-temperature activity and unique long-term operation stability. The process may be applied for production of SO3 for conditioning of flue gases from coal-fired powerplants.
New Generation Of Catalytic Technologies For Environmental Protection On The Base Of Fiber-Glass Catalysts, Bair S. Balzhinimaev, Andrey N. Zagoruiko
New Generation Of Catalytic Technologies For Environmental Protection On The Base Of Fiber-Glass Catalysts, Bair S. Balzhinimaev, Andrey N. Zagoruiko
Andrey N Zagoruiko
Novel glass-fiber based catalysts containing extra-low amounts of noble metals (0.01-0.02% mass of Pt or Pd) demonstrate unique performance in many catalytic reactions, resulted from the ability of the glass fibers to stabilize the transient metals in the glass bulk in a highly-dispersed form. Moreover, specific heat/mass transfer properties, original geometry, high flexibility and high mechanical strength of such catalysts give the way to develop really new catalytic processes and novel reactor designs. The paper is dedicated to the successful research and development (from fundamental research issues to pilot and semi-industrial tests) of different catalytic oxidation processes based on application …
The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher
The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher
Lee J Florea, PhD, P.G.
Florida enjoys the highest density of large springs in North America (Scott et al., 2004); Silver Springs is just one of the 33 first-magnitude springs (mean flow greater than 100 cfs (2.8 m3/s), and there are hundreds of smaller springs (Fig. 6.2; see Meinzer, 1927, and Scott et al., 2004). They are supplied by spectacular underwater caves that are internationally recognized in the cave-diving community. Less well known are the many air-filled caves of the region (see Florea, 2006; Moore, 2006; Lane 1986). Though generally smaller than their aquatic counterparts, their beauty can rival the world’s best show caves. This …
The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea
The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea
Lee J Florea, PhD, P.G.
Eastern Kentucky contains almost the same Mississippian limestones that appear at Mammoth Cave in south-central Kentucky (Chapter 3). To the east these strata dip below the Appalachian Basin and reappear as the Greenbrier Group in the Virginias. The limestone outcrop in eastern Kentucky follows the western margin of the Cumberland Plateau and forms a ragged ribbon of karst that is continuous from southeastern Ohio through Kentucky and Tennessee and into northern Alabama. There are more than 2,000 documented caves comprising over 470 km of surveyed passage in the Kentucky segment of the Cumberland Plateau (Fig. 2.115). At least 14 are …
Caves And Karst Of West-Central Florida, Lee J. Florea, David Budd, Robert Brinkmann
Caves And Karst Of West-Central Florida, Lee J. Florea, David Budd, Robert Brinkmann
Lee J Florea, PhD, P.G.
The real west-central Florida is far from the “Sunshine State” image of white sand beaches and palm trees. Gently rolling hills, dense jungle-like forests, pine and palmetto scrublands, impenetrable cypress swamps, and alligator-laden rivers are more common. Numerous crystal-clear springs offer a glimpse of the hidden world below – a world that could challenge the most imaginative Disney artists (Fig. 6.17).
Incorporating Fairness Motives Into The Impulse Balance Equilibrium And Quantal Response Equilibrium Concepts: An Application To 2x2 Games, Alessandro Tavoni
Incorporating Fairness Motives Into The Impulse Balance Equilibrium And Quantal Response Equilibrium Concepts: An Application To 2x2 Games, Alessandro Tavoni
Alessandro Tavoni
Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts which perform better empirically; one such example is the impulse balance equilibrium (Selten, Chmura, 2008), which introduces a psychological reference point to which players compare the available payoff allocations. This paper is concerned with advancing two new, empirically sound, concepts: equity-driven impulse balance equilibrium (EIBE) and equity-driven quantal response equilibrium (EQRE): both introduce a distributive reference point to …

New Observations Of Gas-Phase Expansion Above A Dense Non-Aqueous Phase Liquid Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson
New Observations Of Gas-Phase Expansion Above A Dense Non-Aqueous Phase Liquid Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson
Sarah E Dickson
The partitioning of volatile dense nonaqueous phase liquid (DNAPL) compounds to a discontinuous gas phase results in the repeated expansion, fragmentation, and vertical mobilization of gas clusters. This process has the potential to significantly affect the dissolution of DNAPL source zones and the characterization of DNAPL-contaminated sites, but has not been included in common conceptual models. This study presents new observations of discontinuous gas-phase growth above a 1,1,1-trichloroethane pool in a two-dimensional flow cell packed with 1.1-mm diameter sand. In contrast to the behavior observed in coarse glass beads, these visualization results show that the gas phase evolves as a …
Uncontrolled Combustion Of Household Wastes And Vegetation Remains In A Rural Community – Questionnaire Results, Robert Oleniacz, Anna Tomkowicz
Uncontrolled Combustion Of Household Wastes And Vegetation Remains In A Rural Community – Questionnaire Results, Robert Oleniacz, Anna Tomkowicz
Robert Oleniacz
Uncontrolled combustion of household wastes and vegetation remains makes a serious problem referring to the emission of many substances polluting atmosphere, including polychlorinated dibenzo-p-dioxins and dibenzofurans. Combustion of post-use wastes or garbage and burning grasses are also seen as one of the causes of air pollution in larger and larger number of communities in Poland. The awareness of the Polish society referring to this problem and related appearance of different air pollutants, including dioxins and furans, has still been low. It was studied in one of Polish rural communities, based on the results of the questionnaires. In the questionnaire studies …

Potential Of Spent Mushroom Substrate In Vermicomposting, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood
Adi Ainurzaman Jamaludin
The potential of spent mushroom substrate from saw dust in vermicomposting were found out through the growth and reproduction of earthworms including the nutrient elements of vermicompost produced at the end of vermicomposting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 80:20 (T1), 60:40 (T2), 50:50 (T3), 40:60 (T4) and 20:80 (T5). After 3 weeks of pre-composting followed by 7 weeks of vermicomposting, T4 showed the highest percentage of growth and reproduction where mean of earthworms’ numbers increases (M = 295.00, SD = 17.32, …

Soumyadeep Mukhopadhyay Dr
This report describes a simple chemical free method that was successfully used by a team of European and Indian scientists (www.qub.ac.uk/tipot) to remove arsenic (As) from groundwater in a village in West Bengal, India. Six such plants are now in operation and are being used to supply water to the local population (www.insituarsenic.org). The study was conducted in Kasimpore, a village in North 24 Parganas District, approximately 25 km from Kolkata. In all cases, total As in treated water was less than the WHO guideline value of 10 mg/L. The plant produces no sludge and the operation cost is 1.0 …
Influence Of Aperture Field Heterogeneity And Anisotropy On Dispersion Regimes And Dispersivity In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
Influence Of Aperture Field Heterogeneity And Anisotropy On Dispersion Regimes And Dispersivity In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
Sarah E Dickson
A 33 factorial experimental design was implemented to numerically investigate the interactive effect of the mean (μ b ), standard deviation (σ b ), and anisotropic ratio (AR) (λ b x /λ b y ) of single-fracture apertures on dispersion regimes (specifically Taylor dispersion and geometric dispersion) and dispersivity. The Reynolds equation was solved to obtain the flow fields in each computer-generated fracture, and the random walk particle tracking method was used to simulate solute transport. The simulation results show that (1) for a fixed hydraulic gradient, the dominant dispersion regime is controlled by μ b , and to a …
Differential Transport And Dispersion Of Colloids Relative To Solutes In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
Differential Transport And Dispersion Of Colloids Relative To Solutes In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
Sarah E Dickson
This work employed numerical experiments simulating colloid and solute transport in single parallelplate fractures, using the random walk particle tracking method, to demonstrate that (1) there exists an aspect ratio of the colloid radius to half the fracture aperture, do, where the average velocities of colloids and solutes are similar. When d > do, the velocity distribution assumption is satisfied, and the fact that the ratio of the colloid transport velocity to the solute transport velocity, sp, decreases as d increases is well documented in the literature. However, when d < do, the velocity distribution assumption is violated, and sp increases as d increases and (2) the Taylor dispersion coefficient and its extension by James and Chrysikopoulos [S.C. James, C. V. Chrysikopoulos, J. Colloid Interface Sci. 263 (2003) 288] will overestimate the colloid dispersion coefficient significantly. Additionally, numerical experiments simulating colloid and solute transport in variable-aperture fractures demonstrated that sp and DL,coll /DL,solute decrease with increasing CoV, and the anisotropy ratio only plays a minor role compared to the CoV. These observations have important implications towards the interpretation of colloid transport in both porous and fractured media.

Review Essay: Disagreeing About The Climate, Donald Nordberg
Review Essay: Disagreeing About The Climate, Donald Nordberg
Donald Nordberg
This paper is an early draft of a review essay that subsequently appeared in the journal Business and Society in 2010. The science concerning climate change is clear, both sides of the argument agree. What they don't agree about is what that clarity means. Each side considers the matter settled, and their points of view unsettle each attempt to make public policy. Mike Hulme, director of the Tyndall Centre for Climate Change Research at the University of East Anglia, thinks the reasons for the persistent differences lies in the complex ways we see and use climate change as a totem …

Dr. Fanan Ujoh
This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …
