Structures for Heat Treatment Assembled from Cast Elements

Regenerative Heat Treatment of Low Alloy Cast Steel

Prediction of Heat Treatment Distortion of Cast Steel C-rings

Navy C-Ring test parts were made of AISI 1022, 4320, 8625, and CF8M steels and heat treated in a designed experiment to evaluate the commercial heat treatment distortion simulation software DANTE. The parts were machined and then measured with a CMM for original dimensions. The parts were then heated and subsequently quenched in two different immersion orientations in agitated water. Temperatur...

Nonlinear lap joint interface modeling and updating strategies for assembled structures

A comparison between two known strategies of modeling lap joint interfaces, namely, zero-thickness and thin layer interface theories and their associated updating procedures, is made. Finite element...

Loop Structures and Barrier Elements from D. melanogaster 87А7 Heat Shock Locus

The three-dimensional organization of the genome is closely related to its functioning. Interactions between parts of the genome located at large distances from each other have been detected within the chromosomes of different organisms, which led to the discovery of topologically associated domains (TADs). Methods that reveal such interactions between chromosomal loci imply detection of both p...

Self-assembled microspheres from f-block elements and nucleoamphiphiles.

Hollow microspheres featuring a hybrid lipid-cation multilamellar shell are prepared by hydration of a nucleoside based amphiphile with an aqueous solution containing either actinide or lanthanide salts. The physico-chemical data collected clearly indicate that the formation of these microspheres is a consequence of the following concomitant stabilizing factors: (i) hydrophobic interactions, (i...
