Well-defined zigzag-shaped ramp-type Josephson junctions between YBa2Cu3O7 and Nb have been studied. The magnetic field dependencies of the critical currents provide evidence for d-wave--induced alternations in the direction of the Josephson current between neighboring sides of the zigzag structure. The arrays present controllable model systems to study the influences of pi facets in high-angle...

Today’s super zoom cameras offer a large optical zoom range of over 30x. It is easy to take a wide angle photograph of the scene together with a few zoomed in high resolution crops. Only little work has been done to appropriately display the high resolution photo as an inset. Usually, to hide the resolution transition, alpha blending is used. Visible transition boundaries or ghosting artifacts ...

1. Depth: Angle formed between the ankle knee and hip while squatting 2. Stance: distance between feet and center of mass over your ankles 3. Back-Hip Angle: Angle formed between the knees hips and back throughout the squat 4. Knee-Toe Alignment: Location and movement of knees throughout the squat • Certain components, such as required depth, stance and the angle at the hip, are fairly well-def...

The deformation and crack initiation mechanisms were analyzed in a textured AZ31B-O Mg alloy subjected to fully-reversed, strain-controlled cyclic along the rolling direction after 50 cycles (approximately 33% of fatigue life). Distinct bands corresponding pyramidal slip or tensile twins found 538 grains out 2100 grains. Slip trace analysis showed that 72.3% 18.4% twin boundaries. Both twinning...

Grain boundary engineered (GBE) materials have improved properties that are associated with the high fraction special Σ3 n boundaries in the microstructure, where n = 1, 2, or 3. Previous experimental studies with high purity nickel before and after GBE thermomechanical processing have shown that the fraction of Σ3 boundaries increased by at least factor of two [1]. Electron backscatter diffrac...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

The evolution of the microstructure changes during hot deformation high-chromium content stainless steels (martensitic steels) is reviewed. microstructural taking place under high-temperature conditions and associated mechanical behaviors are presented. During continuous dynamic recrystallization (cDRX), new grains nucleate growth in materials with high stacking fault energies (SFE). On other h...

316L stainless steel samples were prepared by selective laser melting (SLM) and annealed at 1000 °C for durations of between 1 6 h to investigate both the kinetics microstructural evolution during heat treatment effect annealing on mechanical properties. The as-printed materials contain a high density oxide particles dislocations, forming dislocation cell substructure that shows thermal stabili...
