... of adequate field-based ecotoxicological data combined with well-designed and highly controlled laboratory studies, ultimately providing adequate lab-to-field extrapolation potential. Field-based ecotoxicological data can be collected using a combination in situ exposure and evaluation at various life...

... A novel portable/ in situ Stress-Strain Microprobe (SSM) system was used to measure true-stress/true-plastic-strain (σ t -ϵ p ) behavior of several met llic materials, welds, and their heat-affected-zones (HAZs) in various metallurgical and damage conditions. The SSM system utilized...

... in CMC and MMC. These techniques use longitudinal (bulk) wave and surface wave ultrasonic energy to interrogate the composite specimens, in situ , during mechanical testing. Changes in surface and longitudinal wave characteristics are compared with stiffness changes for extensometer measurements during...

... This paper discusses the use of an unique integrated Nondestructive Evaluation (NDE)/Mechanical test system to characterize the damage progression in a ceramic matrix composite (CMC) under tensile and fatigue loading conditions. During the tests, the effects of damage were characterized in situ...

... Coal tar contamination was encountered at a former coal gasification site in soils below the groundwater table, and in the sediments of the adjacent river. Ex situ remediation techniques at this site would be costly because of the need to dewater the impacted media. In situ solidification...

... field-scale in situ sealed double-ring infiltrometer block samples Craig H. Benson I, Fransiscus S. Hardianto 2, and E. Sabri Moran 3 REPRESENTATIVE SPECIMEN SIZE FOR HYDRAULIC CONDUCTIVITY ASSESSMENT OF COMPACTED SOIL LINERS REFERENCE: Benson, C. H., Hardianto, F. S., and Moran E. S...

... This paper presents the findings of laboratory and field studies undertaken to assess the feasibility of in situ management of contaminated sediments in Port Hope harbor. The contaminated sediments stem from historic releases from an adjacent radium and uranium refinery, and uranium, arsenic...

... New chemical measurement techniques are continually being developed to improve detection limits, accuracy, reliability, and to obtain data in situ or in real time. Recent work has been done in the development and application of fiber optics and fiber optic sensors (FOS) for the measurement...

... An effort was undertaken at the Environmental Protection Agency's (EPA) Environmental Research Laboratory, Narragansett (ERL-N), Rhode Island, to evaluate the integration of in situ biological monitoring with the blue mussel, Mytilus edulis L., into EPA's Complex Effluent Toxicity Testing...

... integrated packages: controller and data acquisition system, mechanical system, volume/pressure compensator, and power supply. This paper describes the ASSP system and presents results of in situ vane tests in a deep sea (5845 m) illitic clay and shallow water (60 m) clayey silty fine sand. The in-situ shear...

... This paper presents a review and analysis of a number of methods of correcting laboratory strength values to in-situ strengths. Methods presented are (1) utilization of an empirical correction factor, (2) use of an analytical model to extrapolate in-situ strength values from tests on disturbed...

... at points along the pile length. Most of the existing methods for obtaining P-y curves are highly empirical. Often little account is taken of the method of pile installation. The pressuremeter offers an almost ideal in-situ modelling tool for determining directly the P-y curves for a pile...
