Preparation Process of In Situ MgB Material with Ex Situ MgB Barrier to Obtain Long Sections of Superconducting Multicore Wires.

In the present study, our emphasis was directed towards the fabrication process of long multi-core superconducting wires, each spanning several hundred meters. These wires feature an in situ MgB core, an ex situ MgB barrier, and a copper shield. The cost-effectiveness of these constituent materials, coupled with a judicious arrangement of internal components, facilitates the utilization of an economical shielding material for the resulting wire.

The description of vascular variations in three-dimensional space: a novel method of spatial cerebral arteries evaluation.

Background: Anatomical and clinical descriptions of variations in arteries are based solely on anatomical terminology. New diagnostic techniques depend on terms such as the anterior, posterior, superior, inferior, medial, and lateral location of arteries and their branches or bifurcations, trifurcations, and fenestrations. However, these methods may be obsolete and such a simplistic approach is inadequate, especially for procedures that require precise morphological and morphometrical descriptions in 3D space.

Digital analysis of the dynamics of the arterial supply to the human foetal kidneys.

Variations in the renal arteries in human individuals and foetuses have already been well studied. Contemporary trends in visualisation techniques focus on the evaluation of the dynamic parameters of blood flow in the vessels (speed, pulsatility, resistance). Most of these data have been obtained by the means of Doppler ultrasound (Fig.
