Summary : Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report outlines the HITEC Technical Evaluation Plan for large seismic isolator and energy dissipation devices. The plan is designed to characterize the fundamental properties and performance characteritics of a wide range of devices produced by U.S. and overseas manufacturers. It describes a program of full-scale dynamic tests, the results of which should provide guidance to the transportation-engineering community regarding the performance of large seismic devices.

Summary : Papers from the June 1995 symposium describe recent discoveries in the genetics, biochemistry, biology, pharmacology, and clinical aspects of neuropeptide research. After a history of the field, coverage includes the use of transgenic and knockout mice in neuropeptide research; CRF- receptor subtypes; individual differences in responses to the behavioral actions of peptides; new peptide-processing enzymes; neuropeptidase gene regulation; interactions and coexistance of neuropeptides and serotonin in spinal autonomic systems; and peptide modulators of serotonin pathways.

Summary : Prepared by the Environmental Technology Evaluation Center (EvTEC), a service center of CERF/IIEC. This Technology Verification report describes the nature and scope of the environmental evaluation of the performance of the Plasma Enhanced Melter? (PEM?) system for waste treatment. The evaluation was conducted through a cooperative program established in 1998 between the Washington State Department of Ecology, Integrated Environmental Technology Inc., Allied Technology Group, and the Civil Engineering Research Foundation. The goal of this report is to provide potential users and purchasers of the PEM? system with information they need to make more informed decisions regarding the performance of PEM? as an equivalent or alternative to incineration for treating hazardous waste.

Summary : Prepared by the Highway Innovative Technology Evaluation Center, a CERF/IIEC Innovation Center. This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the Tricon System for use as a technically viable, precast, mechanically stabilized earth-retaining wall system. The evaluation considered material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol.

Summary : Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF/IIEC Innovation Center This report describes a HITEC evaluation designed to determine the basic capabilites and limitations of the Geo-Con VERT Wall for use as a technically viable permanent excavation support retaining wall system. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Geo-Con VERT Wall System is an in-situ retaining wall system intended as an alternative to other types of cut walls such as soldier pile and anchored retaining walls. Geo-Con VERT Wall System is comprised of: deep soil mix columns consisting of overlapping or tangent soil-cement columns along the front face backed up by tangent rows of overlapping soil-cement columns; a soil-cement relieving platform overtop the columns; steel beams embedded in the front face soil-cement columns for support of the permanent facing; and permanent facing consisting of precast, reinforced concrete panels or reinforced cast-in-place concrete. The relieving platform is intended to provide internal stability by typing the soil-mix columns together and transferring the load to the bottom of the columns.
