The non-Cu critical current density of Nb3Sn strands has been pushed towards 3000 A/mm2 (12 T, 4.2 K) by increasing the Sn content and reducing the interfilamentary Cu. We compare the susceptibility to A15 filament breakage (under 0.5% bend strain) of the new high-Jc internal Sn conductor geometries with both high-Jc Powder-in-Tube (PIT) and low hysteresis loss distributed filament ITER designs...

Whereas most plants are flexible structures that undergo large deformations under flow, another process can occur when the plant is broken by heavy fluid-loading. We investigate here the mechanism of such possible breakage, focusing on the flow-induced pruning that can be observed in plants or aquatic vegetation when parts of the structure break under flow. By computation on an actual tree geom...

The use of composite structures in engineering applications has proliferated over the past few decades. This is mainly due to their distinct advantages of high structural performance, high corrosion resistance, high strength and weight ratio. They are however prone to fiber breakage, matrix cracking and delaminations which are often invisible. Although there are systems to detect such damage, t...

Nijmegen breakage syndrome (NBS) is a rare autosomal recessive syndrome of chromosomal instability mainly characterized by microcephaly at birth, combined immunodeficiency and predisposition to malignancies. Due to a founder mutation in the underlying NBN gene (c.657_661del5) the disease is encountered most frequently among Slavic populations. The principal clinical manifestations of the syndro...
