A Quasicrystal for Denmark's Coast
The first true quasicrystal structure will have been built in the fall of 1993 at COAST (The Center for Art, Science, and Technology at the Danish Technical University). With 600 aluminum...

Characterisation of Anhydrous Cement Clinker by Backscattered Electron Imaging and Energy Dispersive X-Ray Analysis

Analysis of Sand Movement on Noto Coast by Geochemical Method
The analysis of sand samples by X - ray fluorescent spectroscopy (abbreviated by XRF) gives the ratio of the geochemical elements to construct the sand samples. This shows the geochemical...

Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...

Heavy Metal Pollution of Santa Catarina Island, Brazil
On Santa Catarina Island, Brazil, mangrove ecosystems although considered by present legislation as 'Areas of Permanent Preservation', have been undergoing progressive elimination for...

Radiographic Visualization in Experimental Soil Mechanics
A summary of the principles of such methods is presented, i.e. stereophotogrammetry, infrared thermography and radiography and their respective ranges of applicability are discussed. Then,...

Alkali Activation of Class C Fly Ash

Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
