Shearographic and holographic assessment of defective laminates with bond-lines of different elasticities
Article Abstract:
The size and depth of the defects in laminates having adhesive layers of different elasticities are determined by a mathematical method based on the theory of thin plates supported by a Winkler type elastic foundation. For this method, the current elasticity of the adhesive layer is not to be pre-determined. The defects of the laminates possessing a thick and highly elastic bond-line present in foam-adhesive bonded metal laminates and laminates constituting a thin and brittle bond-line present in multi-layered glass-fiber reinforced plastic plates are observed.

An abridged life-cycle assessment of electric vehicle batteries
Article Abstract:
An abridged life-cycle assessment of electric vehicle batteries revealed that nickel-metal hydride batteries pose the least risk to the environment. There is no infrastructure, however, available to recycle these batteries. Sodium-sulfur batteries have low toxicity but still pose problems because they are not recyclable. Lead-acid and nickel-cadmuim batteries, on the other hand, are highly recyclable but their toxicity is not yet fully determined.

ORI's self-assessment: a batting average of .920?
Article Abstract:
The Office of Research Integrity has made substantial progress towards reducing its backlog of cases. It also claims that it has improved its success rate for guilty findings to 92%, but some outside experts say the agency is still plagued by problems and spends too much time on small cases.
