Myocardial Wall Stress: A Clinician's View
Definition of left ventricular (LV) wall stress is a parameter which has a valid application in clinical medicine. This paper discusses this application as it pertains to various cardiac...

Large Deformation Analysis of Cardiac Structures
The finite element technique can be used to simulate the response of the cardiac structures that have complex shape and geometry and nonlinear material properties. This paper enumerates...

Assessment of Left Ventricular Flow Dynamics Using the Finite Analytic Method: Potential for Clinical Applications
Left ventricular (LV) function is traditionally assessed from chamber wall motion, rheological properties of the myocardium, and invasive measurements of chamber pressure. In order to...

Spherical Shells with Nonuniform Rigidity
An iterative finite difference technique is presented in this paper for the analysis of axisymmetric spherical shells with variable wall thickness. The proposed method of solution is based...

A Particle Beam Simulation
A two-dimensional beam simulation is developed in which the beam is composed of uniform rectangular blocks. Internal forces in the beam are caused by relative motion between adjoining...

Inspection Goes High Tech
Many believe that rehabilitation of the existing infrastructure�not net construction�will dominate the 1990s. Therefore, accurate condition assessment is crucial, since public works agencies...

Hurricane Retrofit
Houston's Sheraton Hotel and Convention Center has been retrofitted to protect it from panel pop-out (separation from building curtain walls) and curtain-wall separation from...

Recapturing Boston's Heritage
Structural upgrading of Boston's Old State House and Faneuil Hall is part of an extensive restoration project undertaken by the National Park Service at a cost of $10.6 million...

Soil-Cement Mixed Wall Technique
This paper introduces the soil-cement mixed wall technique and its applications for the installation of cutoff walls, excavation support walls and soil-crete columns for soil stabilization....

Up and Down Construction of a 17-Story Building
The One Westwood Building is located on a small site in the Westwood district of Los Angeles. Construction of the 17-story building with 8 levels of subterranean parking was complicated...

Watertight and Earthquake Resistant Joints for Diaphragm Walls
Different types of joints were constructed and tested in the field to evaluate the bond between concrete and partition plate, the effect of tremie pipe location to the quality of concrete...

Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...

Masonry Performance in the Coastal Zone
Investigators from the National Concrete Masonry Association (NCMA) surveyed the coastal areas of South Carolina from Charleston to Myrtle Beach during a seven day period just after hurricane...

CZMA Consistency Opinions: An Undiscovered Body of Law
The Coastal Zone Management Act allows states to block the issuance of Federal licenses and permits if the permitted activity would be inconsistent with the state's Federally...

Induced Subsidence: Environmental and Legal Implications
Subsidence of coastal areas can be induced by withdrawal of fluids from shallow, unconsolidated horizons beneath the shore zone. In southern California, Huntington Beach, Torrance/Redondo...

Moored Systems for Time Series Observations of Bio-optical and Physical Variability in the Coastal Ocean
Recently, multivariable moored systems (MVMS) have been developed to study the ecology and physics of the upper ocean. Concurrent MVMS measurements provide time series of beam attenuation...

Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...

Sea Water Environmental Remote Sensing Application on Daya Bay Nuclear Power Station
Owing to its extensive and complete characterization, remote sensing investigations have a special ability to analyze seawater environments and to monitor pollution at coastal nuclear...

Increased Attention to Ocean and Coastal Protection Legislation in the 101st Congress
For all the grumbling about the ineffectiveness of Congress, the 101st Congress produced a surprising number of critical pieces of coastal- and ocean-related legislation, and began the...

Environmental Impact Assessment and the Conservation of Marine Biological Diversity
Legislation is pending to include assessment of biodiversity in the Environmental Impact Statement process and revise the National Environmental Policy Act to better address the conservation...
