  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Testing WHAM‐FTOX with laboratory toxicity data for mixtures of metals (Cu, Zn, Cd, Ag, Pb)

    The WHAM‐FTOX model describes cation toxicity to aquatic organisms in terms of (a) accumulation by the organism of metabolically‐active protons and metals at reversible binding sites, and (b) differing toxic potencies of the bound cations. Cation accumulation (νi in mol g‐1) is estimated through calculations with the WHAM chemical speciation model by assuming that organism binding sites can be ...

  • Evaluation of Metals, Metalloids, and Ash Mixture Toxicity Using Sediment Toxicity Testing

    In December 2008, a release of 4.1 million m3 of coal ash from the Tennessee Valley Authority Kingston Fossil plant occurred. Ash washed into the Emory River and migrated downstream into the Clinch and Tennessee Rivers. A Baseline Ecological Risk Assessment evaluated risks to ecological receptors from ash in the river system post‐dredging. This paper describes the approach used and results ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • Reinforcing Soil with Aligned and Randomly Oriented Metallic Fibers

    Laboratory direct shear box tests were used to evaluate the strength behavior of a reinforced uniform silty sand. The reinforcement elements consisted of flexible, semirigid, and rigid metallic fibers. The orientations of the fibers to the shear plane were varied and had a marked effect on the shear resistance. Increases in peak and residual strengths of 100 and 300%, respectively, were observed ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • Laboratory Investigation of Earth Walls Simultaneously Reinforced by Strips and Random Reinforcement

    The performance of reinforced earth structures depends, among other factors, on the shear strength of the backfill material used in construction. The shear strength can be enhanced by the use of random reinforcement. This paper presents the result of laboratory investigations concerning the effects of several types of random reinforcement on soil strength and, in particular, on the performance of ...

  • Application: heavy metals in industrial waste water

    Today heavy metals in waste water are seen as one of the biggest problems of pollution. The attention of local governments to decrease the concentration of heavy metals in waste water is continuously increasing. The Problem: The online measurement of Industrial Waste Water introduces two technical problems to be solved. First, the complex waste water matrix will interfere with any ...

  • Bringing powdered metal blending in-house, rotary-style

    When processing powdered metal compounds for products such as gyro rotors, flywheels, counterbalances, boring bars and grinding quills, the proportion of powdered metal ingredients must be precise, and the distribution of those ingredients 100 percent uniform. Mi-Tech Metals, Indianapolis, IN, has been manufacturing products from high-density tungsten-based alloys for more than 26 years, during ...

  • Environmental impacts of aquifer thermal energy storage investigated by field and laboratory experiments

    Aquifer thermal energy storage (ATES) uses groundwater to store energy for heating or cooling purposes in the built environment. This paper presents field and laboratory results aiming to elucidate the effects that ATES operation may have on chemical groundwater quality. Field data from an ATES site in the south of the Netherlands show that ATES results in chemical quality perturbations due to ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Demonstration of DeconGel at Oak Ridge National Laboratory building 2026

    Challenge In 2003 an area behind the hot cells in Building 2026 at the Oak Ridge National Laboratory (ORNL) was flooded with highly contaminated liquids when a liquid low level waste pipe became clogged. The main contaminants of concern are uranium and plutonium. Transferrable contamination levels are in the 1,000,000 disintegrations per minute range. The area is posted as an airborne ...

  • Sorption of heavy metals in the biomass of alga Palmaria palmata

    Sorption of heavy metals by the sea alga Palmaria palmata was investigated in laboratory conditions. The sorption process of the analytes was carried out with constant flow of the solutions through the algae samples. The Langmuir isotherm model was used to describe equilibria. The experiments confirmed that 50 min of exposure of algae with little heavy metal contamination in contaminated ...
