Comparative Radioactivities from Nuclear Excavation
The chief potential value of nuclear excavation is in reduced initial cost. In addition to economic factors, however, practicality and safety of the nuclear method must be assessed for...

Aquatic Plants in Maryland - A Growing Menace
The rapid increase in the population of the Chesapeake Bay Area coupled with the almost explosive increase in tidewater-oriented pursuits has resulted in intensive development of waterfront...

Information Retrieval for Soil Engineers
Authors of soil mechanics literature must facilitate the transfer of information to others by using concise titles, writing informative abstracts giving results and conclusions, and providing...

Mud Floods Related to the Irazu Volcano Eruptions
The ash erupted by the Irazu Volcano in Costa Rica during its period of explosive activity, 1963–65, destroyed the vegetation of the Reventado River upper basin* The direct consequence...

Boiler Column Straightening Upper Load Conditions (1965 Power Division Specialty Conference, in Denver Colorado)
An accidental boiler explosion that occurred at Southern California Edison Company's Alamitos Steam Station provided engineers with an opportunity to test their design under...

Particle-in-Cell Method in Shock Propagation Problems
The paper considers a particle-in-cell approach for the analysis of high velocity impact problems in which large motions preclude the practical use of either a purely Lagrangian or purely...

Soil Surface Compaction with a Foam-Type Explosive
A proposed new method for soil surface compaction based on the principle of pressure waves as a source of energy is described. This method, which has been termed the foamed propellant...

Water Waves Generated by Underwater Explosions

Boiler Column Straightening Under Load Conditions

Educational Requirements for Water Resources Engineers
Water resource development is the provision of an ample supply for all purpose of high quality water at a reasonable price. The explosion in water use and population is demanding the continued...

Nuclear Excavation of a Sea-Level Isthmian Canal
Data on high-explosive and nuclear cratering events are combined with 1947 Route Surveys (Panama Canal Company) to estimate the number and yield of the nuclear devices required to excavate...

Densification of Soils by Explosive Vibration
Densification is compaction applied to unlimited depths from the surface. Densification allows building on granular soils with original bearing values below minimum, reduces or eliminates...

Model Predictions of Fracture Due to Explosions
Evidence indicates that small model systems using the same material, same explosive, and similar geometry give good quantitative predictions of strains in a number of rocks, but only qualitative...

Yielding at Varying Loads Rates
Yield strength of several aluminum alloys were determined experimentally under rates of stress application ranging from 4×105 psi/sec to 19×106...

Landing Area Planning: Aircraft Runway Arresting Barriers (Increasing Airport Capacity An ASCE-AOC Joint Conference 1961)
Barriers are used as emergency devices by Air Force; they consist of engaging device and energy absorbed; 3 types of engaging devices and 4 types of energy absorbers are described; quantitative...

Fundamentals of Arctic Blasting
Materials, according to their behavior in blasting, may be classified into shock type, shear type, or viscous damping type; blast effects are determined by relation between energy of explosion...

Meeting USAF Blast Fence Requirements
Advent of B-52 heavy bomber with 8 jet engines operating in unison under full power has created new requirements for deflecting aircraft blast at both military and civil airports; Air...

Trombay Power Station: Cooling Water System
Station on shore of Bombay Harbor, India; condensing water system and intake conduits; embankment jetty and intake structure....

Behavior of Shock Waves Entering Model Bomb Shelters
Spark shadowgraph with effective exposure time of fraction of microsecond has enabled very sharp pictures to be obtained of time sequence of shock wave advance, reflection, diffraction,...
