The University of North Dakota is developing a plasma reactor system for use in closed-loop processing which includes biological, materials, manufacturing, and waste processing. Direct-current,...
Space Construction Animator: Functional Requirements
This paper explores the idea of developing integrated design/construction tools. In order to develop suitable computer graphics integrated tools for space construction operations, the...
Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...
Probabilistic Methods in Civil Engineering
This book contains extended abstracts of papers presented at the ASCE Specialty Conerence on probabilistic methods held in Blacksburg, Virginia on May 25-27, 1988. The field of probabilistic...
Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...
Out of the Mainstream
By treating only part of the wastewater stream, a biological/chemical phosphorus removal system also reduces chemical costs and sludge production. The system consists of two 60 ft dia...
Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....
Asphalt Pavements of the Future
There will be major changes in the Hot Mix Asphalt Industry throughout the next decade and into the 21st century. Acquisitions, diversification, SHRP, the emergence of new technologies...
New Concrete and Asphalt Mixes on the Horizon
Significant research is currently 'in progress' which is intended to develop modified or new design methodologies that will result in improved pavement performance....
Recovery Efficiency From Single-Well Injection/Recovery Tests in a Limestone Aquifer of High Secondary Porosity
An analytical advection-diffusion model was developed to assess the feasibility of injecting and recovering water in a limestone aquifer of high secondary porosity. The model was calibrated...
Artificial Recharge of Ground Water
A need for international and interdisciplinary technology transfer on the subject of artificial recharge resulted in the American Society of Civil Engineers' (ASCE) Irrigation...
The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...
Managing Dioxin
Dioxins, among the most toxic compounds known to man, are by-products from production of other chemical products. There are currently about 5000 metric tons of dioxin-containing wastes...
Biological Treatment of Trichloroethylene
Trichloroethylene and related compounds such as cis- and trans-1,2-dichloroethylene and vinyl chloride are common contaminants of ground water in industrial areas. In oxygenated ground...
Physical and Chemical Treatment of Contaminated Groundwater at Hazardous Waste Sites
In selecting an appropriate groundwater treatment system, three steps are normally followed. 1. A groundwater investigation is performed to determine the types and concentrations of contaminants...
Malaysian National Coastal Erosion Study
This paper presents an overview discussion of the National Coastal Erosion Study for the Southeast Asian country of Malaysia which was conducted over a 15-month period ending in January...
Optimal Process of the Development of the Residential Area on the Coastal Zone
The concentration of population and assets through various types of development in the coastal zone in Japan is progressing rapidly at present. The conditions of the sea environment are...
The Canadian Experience with Coastal Zone Management
The concept of coastal zone management (CZM) emerged in Canada as a recognizable entity over 15 years ago. Today, the original goal of a national CZM program in Canada is generally considered...
The Location Study for Sea City as Residential Quarters
The objective of this study is to understand the spatial expansion created by community activities in the urban community, as a prior stage to calculate the off-shore distance in the location...
NOAA Weather Radio: The Source of Weather Information 24 Hours a Day
Weather plays an important role in the day to day affairs of coastal communities. The timely and accurate receipt of weather information is critical, especially during inclement conditions....
