Silicate Effects on Iron Treatability in Sequestration

Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...

An Expert System for Diagnosing and Repairing Cracks in Cast-in-Place Concrete Structures

McNary Powerhouse Generating Unit 14 Stator Core and Winding Replacement
The powerhouse contains 14 main generating Kaplan-blade units, each rated at 73,684 kVA at 0. 95 power factor. In early 1985 the decision to rewind and uprate Unit 14 was being finalized....

The Use of Restrained Joint Ductile Iron Pipe
This paper addresses some of the problems we at U. S. Pipe have observed from restrained joint installations during the past several years and the solutions devised. The restrained joints...

Thrust Restraint of Buried Ductile Iron Pipe
It is the intent of this paper to present current state of the art thrust restraint design, present a basis for calculating required lengths of restraint, and to offer some practical suggestions...

Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...

Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...

Effects of Ground Failure on Ductile Iron Pipe
The design studies and procedures outlined in this paper for pipelines that must cross earthquake fault zones are also applicable to similar ground disturbances resulting from landslides,...

Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Feo...

Building Bridges the Old Way
Cast-in-place concrete bridges built on falsework, particularly post-tensioned box girders, are California's dominant structure type. Factors which have led to the popularity...

The Great Highway Coverup
Public opinion has forced changes in highway design since the first ones were built 30 years ago. In the Seattle area, this environmental sensitivity led to federal court action and to...
