Oxygen Mass Transfer to Flowing Ground Water Using Oxygen Microbubbles
Mass balance and transfer of oxygen has been studied from oxygen microbubbles to low dissolved oxygen ground water passing through variously configured pilot scale vertical slice test...

Steady Turbulent Gas Desorption in Surface Condenser Tubes
A one-dimensional steady two-phase separated flow model in conjunction with the energy and mass transfer equations and an associated turbulent mass transfer coefficient model are utilized...

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...

Rehab Roundup
The concrete exterior of San Franciso's Coit Tower was damaged and the murals were being destroyed by water infiltrating the structure. Interactive Resources, Inc., Point...

Taller Tunnels
Between 1984 and 1991, Shannon & Wilson, Inc., Seattle, designed renovation programs for more than 25 mi of tunnels for four western railroads. We performed all of this work under...

Avoiding Defective Specifications
Despite everyone's best efforts, the design intent as portrayed in the contract documents is rarely crystal clear. As a result, the owner and the project team often find themselves...

Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...

Jointless Redecking
If you're redecking a bridge, why not eliminate a major cause of its corrosion at the same time? Why not remove the expansion joints? The Department of Public Works in Steuben...

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...

Update: Bridge Scour
Nearly 500 bridges have failed because of hydraulic conditions�primarily scour�since 1950, but the collapse of the Route 90 bridge over Schoharie Creek in April 1987 focused national attention...

Rehabbing the U.S.
When it comes to protecting its $1.4 trillion investment in public-works infrastructure, the U.S. has been like a homeowner who puts off fixing a leak until the ceiling lands on his head....

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...

Quake-Safe Housing, Again
Because so little data exist about earthquake behavior of buildings that have been strengthened to meet seismic codes, many engineers are curious about the Hotel Oakland in California...

Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....
