Salt-water recycling for brine production at road-salt-storage facilities

ENVIRONMENTAL PROGRESS & SUSTAINABLE ENERGY, Issue 4 2009
G. Michael Fitch
Abstract This research investigates the storm-water quality at road-salt-storage facilities located at Virginia Department of Transportation (VDOT) winter maintenance locations and investigates the feasibility of a sustainable solution to better manage the salt-contaminated storm-water runoff. Collection ponds are currently used at most salt-storage sites to contain highly saline runoff and prevent its release into the environment. During a synoptic, winter-time sampling, chloride-ion concentrations in these ponds were found to be significantly greater than state and federal regulatory guidelines for surface-water-quality criteria, with individual values exceeding 2000 mg/L. The pond water is currently treated as a waste product by VDOT, resulting in significant costs for disposal. However, this saline pond water can potentially be recycled to produce concentrated brine solutions, which can then be used by VDOT for either prewetting dry salt during application to roadways or for direct brine application. Laboratory and field tests have been performed using a bench-scale brine generation system to quantify the effects of hydraulic retention time, temperature, and influent-water quality on system performance. Results of these studies have found that the storm-water runoff captured in collection ponds requires no pretreatment before entering the brine generation system and can effectively produce brine at the target salt concentration. Results of a cost-benefit analysis indicate that it is possible under multiple scenarios to recover the investment capital of implementing brine generation at all VDOT winter maintenance locations, typically within a 4-year horizon. © 2009 American Institute of Chemical Engineers Environ Prog, 2009 [source]


Genetic quality of domesticated African tilapia populations

JOURNAL OF FISH BIOLOGY, Issue 2004
R. E. Brummett
Anecdotal and empirical evidence exists for substantial (up to 40%) declines in growth among Oreochromis populations domesticated in both large and small-scale fish farms in Africa. These declines are at least partly attributable to poor genetic management, including inadvertent selection, inbreeding, bottle-necks and founder effects. Due to restricted cash flow and investment capital, genetic management and selective breeding for the improvement of domesticate populations are difficult for small-scale farmers, but feasible on larger-scale farms. In managing domesticated gene pools, feral populations can serve as a broodstock reservoir, making the use of indigenous species advantageous. A development model of large-scale hatcheries producing selected lines of sex-reversed, indigenous tilapia for sale to smaller-scale farmers is proposed as a solution to the problems of poor genetic management in African aquaculture.

A Model of Community,Based Venture Capital Formation To Fund Early,Stage Technology,Based Firms

JOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 4 2002
Howard Van Auken
This paper suggests a model of capital formation that concurrently establishes a mechanism to fund early,stage technology,based firms and meets the economic development needs of rural communities. Investors in a community capital investment fund can gain high rates of return on investment while firms realize all of the benefits associated with the investment, community support, and expanded network. The model includes factors associated with the community environment (community,based factors that impact community members' participation) and external support environment (factors that facilitate the accumulation of investment capital within a community). The result of a community effort can be an environment in which members of the community contribute to an investment fund, cooperate in attracting firms, and provide networking assistance to new business owners. Communities benefit through job creation and economic stability. Community members benefit through wealth creation. [source]


2.,A New Framework for Macroeconomics

AMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY, Issue 4 2009
Achieving Full Employment by Increasing Capital Turnover
Most forms of macroeconomics today, whether Keynesian or monetarist, presuppose that problems of economic instability can be treated as errors in financial management. Neither fiscal nor monetary policy recognizes the existence of systemic faults in the real economy that result in overinvestment in durable capital that turns over slowly, in contrast to forms of capital that interact more frequently with land and labor. Only by removing serious distortions in microeconomic relations can macroeconomic problems be resolved. The current global economic crisis exemplifies the limitations of policies that ignore distortions in the rate of turnover of investment capital. [source]


Presidential Address: Asset Price Dynamics with Slow-Moving Capital

THE JOURNAL OF FINANCE, Issue 4 2010
DARRELL DUFFIE
ABSTRACT I describe asset price dynamics caused by the slow movement of investment capital to trading opportunities. The pattern of price responses to supply or demand shocks typically involves a sharp reaction to the shock and a subsequent and more extended reversal. The amplitude of the immediate price impact and the pattern of the subsequent recovery can reflect institutional impediments to immediate trade, such as search costs for trading counterparties or time to raise capital by intermediaries. I discuss special impediments to capital formation during the recent financial crisis that caused asset price distortions, which subsided afterward. After presenting examples of price reactions to supply shocks in normal market settings, I offer a simple illustrative model of price dynamics associated with slow-moving capital due to the presence of inattentive investors.
