APPLICATION OF ECOSYSTEM ENERGETIC INDICATORS FOR THE VALUATION OF ECOSYSTEM SERVICES AND HEALTH
(2014)
Ecosystems services are benefits that humans receive from ecosystem functions. Ecosystem health is a term that is commonly used in the literature to describe the state of an ecosystem. Ecologists and economists have stated ...
Using Physicochemical Properties Within a Discrete Element Modeling Framework and Fractal Geometry Theory to Understand Behavior of Unsaturated Expansive Clays
(2023-12-15)
The volumetric deformations associated with expansive soils pose a risk to infrastructure, costing billions in mitigation annually. Many engineering designs assume the soil is in either the dry state or fully saturated. ...
State-of-the-art of land treatment of corrosive and ignitable waste /
(1985)
This research was conducted to provide state-of-the-art information on land application of ignitable (D001) and corrosive (D002) waste (ICW). Land application is considered a relatively new technology and there is very ...
Augmenting the Applicability and Efficiency of Ecological Engineering Solutions for Water Quality Improvement
(2010)
The design options available to the ecological engineer were expanded by exploring new sustainable water quality improvement techniques, specifically the applicability of passive treatment of acid mine drainage (AMD) in ...
Computer design of onsite residential lagoons from demographic, hydraulic and hydrologic variables /
(1985)
An investigative field study of onsite residential lagoon systems was conducted to identify important demographic, hydraulic and hydrologic variables affecting components of lagoon water balances. The goal was development ...
Impacts of heterogeneous sedimentary organic matter on phenanthrene sorption and fate processes.
(1999)
Natural attenuation is currently one of the most important topics in groundwater management. Sorption and biodegradation are key processes impacting the efficiency of natural attenuation. Although extensive literature has ...
Effect of additives on surface free energy characteristics of aggregates and binders in hot mix asphalt.
(2007)
U.S. spends approximately $20 billion/year on asphalt pavements with disproportionately high maintenance costs of $9.3 billion/year. Better performance of asphalt pavements is crucial to reducing these maintenance costs. ...
EVALUATION OF RHEOLOGICAL PROPERTIES OF ASPHALT BINDERS FOR PAVEMENT DESIGN APPLICATIONS
(2011)
More that 90% of the total paved roadways in the U.S. are asphalt concrete (AC) pavements. The annual expenditures for construction and maintenance of these pavements exceed $10 billion. To reduce these maintenance costs, ...
The poromechanics of naturally fractured rock formations: A finite element approach.
(2003)
The mathematical models have been cast into finite element form and verified against analytical solutions for one-dimensional consolidation and an inclined wellbore in a fully saturated single-porosity formation subjected ...
Failure mechanisms of buried pipelines under fault movement and soil liquefaction /
(1983)
A simplified pipe model on a time dependent elastic foundation is proposed to stimulate a liquefaction situation of a liquefiable zone during earthquakes and the finite difference technique coupled with a time-increment ...
