Nutrient Loadings Into Conesus Lake
… the results of measurements for stream nutrient loadings, effects of the Inlet wetland on nutrient dynamics and road salt loadings. N0 3 -N loading upstream of the Conesus Inlet Wetland that was consistently about 2.5 times higher than downstream suggests nitrogen removal by denitrification in …

Aesthetic pollutant loadings in upstream combined sewers.
An improvement to the standard of discharges from combined sewer overflows is necessary to meet the challenges set by the EC Urban Waste Water Treatment Directive (1991). To prevent aesthetic pollutants being discharged from a CSO, it is first necessary to gain an understanding of the quantity and …

Pore-water pressure accumulation under dynamic loadings
The primary objective of this dissertation is to study the impact of closely spaced low-magnitude earthquakes or other dynamic events on the stability of upstream raised tailings dam. For this purpose, a series of numerical analyses were conducted and the level of excess pore-water pressure …

The Fatigue of Weldments Subjected to Complex Loadings
Cruciform and double-strap lap weldments were fatigue tested under constant amplitude axial load and SAE Bracket Spectrum load conditions. For the cruciform weldments, fatigue cracks generally initiate at the root but may initiated the toe if higher bending stresses are induced by joint distortion. …

Comparing the responses of nitrifiers to differing ammonia loadings
Return active sludge from the Danville Sanitary plant (Danville, IL) was fed 10 mg NH3-N/L per cycle of separated swine manure to allow the biomass to adapt to a new influent in a sequencing batch reactor. The biomass was then separated into three reactors. A control reactor was exposed to 10 mg …

Estimating Bacterial Loadings to Surface Waters from Agricultural Watersheds
Fecal bacteria and pathogens are a major source of surface water impairment. In Virginia alone, approximately 73% of impaired waters are impaired due to fecal coliforms (FC). Because bacteria are a significant cause of water body impairment and existing bacterial models are predominantly based upon …

Modeling the hydrologic and particulate loadings from paved urban surfaces
This dissertation details the results of recent investigations concerning non-colloidal particulate matter found in urban rainfall-runoff and urban snowmelt. Three forms of the power law model (PLM) were used to model particle number density. It was found that significant model error could be …

Optimum Design of Composite Wing Spar Subjected to Fatigue Loadings
<p>Composites are now being incorporated into aircraft designs because of their high strength to weight ratio compared to traditional metal materials. Due to the complexity of the material, composite parts are presently being over designed to satisfy static and fatigue requirements. A greater …

A study of the effects of differential loadings on cofferdams
Conventional design of cellular cofferdams is largely based upon semi-empirical concepts derived from classical earth pressure theories. Recent studies have suggested that most existing design methods are excessively conservative. In part, this derives from an inability to fully describe the true, …

The response of a suction anchor group to various applied loadings.
The results of a study of the behaviour of buried suction anchors tested singly and in a group arrangement are presented and discussed. The tests were conducted in saturated granular soil, contained in a 1.8 m diameter tank, in both loose and dense states. The model anchors and the test apparatus …

Procedure to Quantify Environmental Risk of Nutrient Loadings to Surface Waters
… to quantify environmental risk of nutrient loadings to surface waters and to demonstrate the procedure on a watershed. A procedure to quantify environmental risk of nutrient loadings to surface waters was developed. The risk is identified as the probability of occurrence of a nonpoint source …

Vibrations of and sound radiation from some periodic structures under convected loadings
… cylindrical shells excited by random convected loadings. The sound power radiated under these conditions is also dealt with. The stiffened structures are represented by uniform beams, plates or shells on periodically spaced elastic supports which represent stiffener-skin interaction forces and …

Response of grooved composites to transversely distributed and localized spherical contact loadings
The response of a grooved composite specimen to two contact loading situations is studied; load applied via a transversely oriented cylindrical indenter and via a localized spherical ball-ended indenter. The philosophy of the Building Block Approach is used to develop these tests in the current …
