The EAHWM was developed to help Army decision makers find and evaluate viable minimization alternatives to current hazardous waste management practices. This tool has been widely accepted throughout the Army and is being assessed by the US. Navy and the Department of Defense General Supply Center. Law and policy makers in the government and private industry can also use the model to compare min...

In this paper, we propose toll-setting as an alternative policy tool to regulate the use of roads for dangerous goods shipments. We propose a mathematical formulation as well as a solution method for the hazardous materials tool problem. Based on a comparative analysis of proposed mathematical models, we show that toll policies can be more effective than the popular network design policies that...

This study was undertaken to investigate whether certain hazardous chemicals were present as components in new carpets, and if so, in what quantities. The study included analysis of eight new carpet samples that were available for retail in the UK. Some of the carpet samples contained high levels of organotins, in particular TBT (up to 47,500 ppb). One sample contained high levels (1600 ppb) of...

Current hazardous waste disposal policies in the Home Health Care setting were evaluated as it related to the need for better regulation of hazardous materials entering residential waste streams. It was found that all waste materials from home care visits with the exception of “sharps,” were placed directly into residential waste streams. Therefore, large volumes of potentially hazardous waste ...

Decision making in environmental problems is a complex task due to multiple and often conflicting criteria, varying measurements, qualitative and quantitative input parameters, and lack of exact data. In this paper, we propose a multi-criteria decision making (MCDM) model based on an integrated fuzzy approach in the context of Hazardous Waste Recycling (HWR). The proposed method: (a) takes into...

We present a new sum-of-product-based asynchronous architecture, called the N-SHOT architecture, that operates correctly under internal hazardous responses and guarantees hazard-freeness at the observable noninput signals. We formally prove that within this architecture, a very wide class of semimodular state graphs with input choices (either distributive or nondistributive) that satisfy the co...

INTRODUCTION Postmortem studies suggest that fibrillar brain amyloid places people at higher risk for hazardous driving in the preclinical stage of Alzheimer's disease (AD). METHODS We administered driving questionnaires to 104 older drivers (19 AD, 24 mild cognitive impairment, and 61 cognitive normal) who had a recent 18F-florbetapir positron emission tomography scan. We examined associatio...

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and universities completed measures of behavioral accul...

As do many industries, colleges and universities encounter thorny problems in dealing with hazardous wastes. Industry and academia alike are saddled with the rising cost of waste management and face perpetual liability for costs of waste cleanup. Unlike many industries, however, colleges and universities generate small amounts of waste, most, but by no means all of which is generated in laborat...

It has been transferred to an electronic format to allow faster and broader access to important information and data. While the Center makes every effort to maintain a level of quality during the transfer from print to digital format, it is possible that minor formatting and typographical inconsistencies will still exist in this document. Additionally, due to the constraints of the electronic f...
