A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Structural Concrete, EarlyView.Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Structural Concrete, EarlyView.Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found

Structural Concrete, EarlyView.Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa
Structural Concrete, EarlyView.Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950
Gender &History, EarlyView.ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Evaluating the efficacy of tagging adhesives for insect tracking
Agricultural and Forest Entomology, EarlyView.Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

Boreas, EarlyView.We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Delipidisation of wool fibres and the subsequent beneficial properties of delipidised wool fibres
Coloration Technology, EarlyView.Abstract Wool fibres are complex matrices of proteins and fatty acids/lipids found both internally and externally. 18‐methyleicosanoic acid (18‐MEA) is covalently bound to the surface of the fibre via a thio‐ester link, and is considered one of the most important lipids as it is responsible for the hydrophobic properties of wool fibres.

Compatibility of personal care thickening polymers in sulphate‐free surfactants
International Journal of Cosmetic Science, EarlyView.Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘
