 | Carbon reinforced polymer composites are extensively used in aerospace and marine applications. Carbon fibers in carbon reinforced composites, being electrically conductive, form galvanic couples when they come into contact with most metals in the presence of an electrolyte. Carbon is a noble material and becomes a cathode in the galvanic couples with steel, aluminum, etc. The galvanic couple resulted in blistering of these composites whereas uncoupled samples did not show ... |

| The electrochemical nature of blistering in carbon vinyl ester composites in sea water and saline solution was confirmed. Carbon fiber/ polyester composites also blistered. It was therefore shown that blistering is a generic degradation phenomena for many carbon containing polymer composites. The location of the fluid filled blisters in the composites was detailed. The aqueous blister liquid contains organic species and has a pH greater than 10. Blisters formed on ... |

|
 | Two bedrock valleys, filled with glacial outwash material, were investigated with Schlumberger resistivity soundings. Aquifer electrical resistivities were determined for 6 vertical electrical soundings at seven sites in southern Rhode Island where pumping tests had been run previously. Resistivities for the different aquifer materials were derived with boring log control. The auxiliary point methods were used to reduce the aquifer layering to a single representative resistivity value. Relationships between the ... |

|
| The geometric and kinematic modes of material removal have been determined for four types of aluminas under differing environmental conditions and for various system parameters. The effect of various liquid environments on the force levels generated in single point diamond grinding of three alumina ceramics has been determined. The liquids used were water, n-alkanes, n-alcohols, toluene and carbon tetrachloride. The effects of these liquids were compared with the dry environment ... |

|
| The vertical breakout behavior of the hydrostatic anchor depends greatly upon the anchor geometry including anchor diameter and skirt length, the soil strength properties, and the pressure difference between the ambient pressure and that underneath the porous stone. For the range of conditions studied, the anchor capacity increased linearly with increasing pressure difference provided that the anchor skirt length based upon the Coulomb failure theory resulted in an equation which ... |
