Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

A N,N′‐p‐Tolyl Substituted Diazadiene Ligand with a Dithienylethane Backbone in Hexacoordinated Group IV Tetrachlorido Complexes—Steric Repulsions Govern the Axial Chirality Mode

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The chelating imino groups in [MCl4(DADDTEthane)] (M = Ti, Zr, Hf) give rise to a planar five‐membered (‐N=C‐C=N‐)M metallacycle. The two thiophene rings of the ligand backbone reside in a noncoplanar arrangement concerning the metallacycle, giving rise to two chiral C–C axes in the ligand backbone.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Deciphering unusually large modulations in two related organic hydroxy channel structures

Acta Crystallographica Section B, EarlyView.
Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

Axial muscle‐fibre orientations in larval zebrafish

Journal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.
