Multiscreen serum analysis of highly sensitized renal dialysis patients for antibodies toward public and private class I HLA determinants: Implications for computer-predicted acceptable and unacceptable donor mismatches in kidney transplantation [PDF]

, 1990
A multiscreen serum analysis program has been developed that permits a determination of antibody specificity for the vast majority of highly sensitized patients awaiting transplantation.

Geometry Controls Confined Water Dynamics in Lipidic Mesophases

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.
An archaeal‐inspired lipidic mesophase allows precise control of interfacial curvature and water‐channel connectivity. Combining structural, thermodynamic, and ultrafast spectroscopies, we reveal that curvature governs the structure and reorientation dynamics of confined water, establishing a molecular‐level link between topology and dynamics in soft ...

Elastoplastic Fracture Analysis of the P91 Steel Welded Joint under Repair Welding Thermal Shock Based on XFEM

Metals, 2020
P91 steel is a typical steel used in the manufacture of boilers in ultra-supercritical power plants and heat exchangers in nuclear power plants. For the long-term serviced P91 steel pressurized structures, the main failure mode is the welded joint ...

Creep crack growth behavior of P91 steel weldments

Thermal Science, 2019
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i.e. secondary creep process. Therefore, creep crack growth (CCG) tests were carried out on compact tension (CT) specimens machined from P91 weld joint at 600°C to determine its behaviour in realistic ...

Anchors or relational risks? Educator and psychologist narratives of attachment in child–robot relationships

British Journal of Educational Psychology, EarlyView.
Abstract Background As AI‐enabled social robots become more common in schools, children may form strong emotional bonds with them despite robots not being caregivers and lacking the capacities for “true” attachment. Given limited understanding of potential risks and safeguards, professional perspectives are needed to inform responsible design and ...

Applicability of the induction bending process to the P91 pipe of the PGSFR

Nuclear Engineering and Technology, 2021
The application of induction bending processes to industrial pipe production is increasing. The induction bending process has the effect of reducing the number of inspections and preventing leaks by reducing the weld of the pipe.
