Scheduling for Effectiveness
Telephone calls, drop-in visitors and the assorted instant crises that arise in the course of a busy workday can leave engineering and construction professionals feeling they have little...
Building Green
Some scientists say polystyrene insulation may be responsible for up to 40% of the ozone depletion caused by CFCs. That's only one reason why construction and design professionals...
Future Fill-Up
The car rental agencies at Phoenix Sky Harbor Airport have combined their service/filling facilities in the new terminal's parking garage. This permits customers to pick up...
Landfill Park: From Eyesore to Asset
By reclaiming a 50 acre landfill as a recreational area, Cambridge, Mass. increased its open space by 20%. The park includes three softball and three soccer fields, one multisport field,...
Regional Estimates of Gas Transfer Using an Airborne System
The aircraft-based eddy correlation technique was recently used to obtain regional observations of transfer processes of sensible and latent heat as well as carbon dioxide over wetlands...
Airborne Remote Sensing of Breaking Waves with Implications for Gas Exchange
It is shown that airborne remote sensing can potentially relate gas mixing effects within a temporally evolving breaking wave to relectivity changes, and can identify the intensity of...
Structure of the Drift Current Observed Below Capillary-Gravity Waves
Measurements by laser-Doppler velocimeter were performed in a wind-wave tank to investigate the structure of the water surface boundary layer under capillary-gravity wind waves in the...
Parameterization of Air-Ocean Gas Transfer
A renewal-type model, based on the physics of a molecular sublayer, allows the derivation of parameters to describe air-ocean gas transfer and the temperature difference across the cold...
Designing Better Hollow Fibre Contactors
In this paper we calculate optimum hollow fibre module designs for gas absorption by maximizing the mass transferred per unit cost. Two costs are considered; the membrane cost and the...

Kuwait: The Incredible Shrinking Rehab
With rehabilitation estimates now just 20% of what they first were, the liberation of Kuwait has not been a cure-all for the construction industry. Firms participating in the emergency...
Pounds, Kilos and Newtons
In the U.S., an aura of mystery, like the glamour afforded the medieval priest by his mastery of Latin, surrounds the Syst�me International. This unreasonable awe, largely generated by...
The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...
Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
Where Does Rock Begin for Three Highway Projects?
'Where does rock begin?' was a question raised on three large highway projects in the western United States. The question was successfully answered by a variety...
The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...
Yazoo River Basin a New Direction for the Corps
The paper presents the lessons learned from the past events in the Yazoo Basin. The Yazoo Basin project is the only mechanism available that can provide the flood control that is needed...
Recent Advances in Cone Penetrometer Measurements (Software and Hardware) and Its Application to Liquefaction Susceptibility
Some of the recent advances made in Cone Penetration Test (CPT) data acquisition system and real time processing of CPT data are presented. A key component of the new CPT data acquisition...
