Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

open access: yessteel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

A Semi‐Quantitative Methodology for Chemical Process Resilience Assessment

open access: yesSafety Science and Technology, EarlyView.
A new semi‐quantitative framework is proposed for process resilience assessment. Safety/security, productivity, and quality are integrated into the resilience evaluation. Dynamic simulations are used to quantify resilience as a time‐dependent system response.

Imaging in gynecological disease (32): clinical and ultrasound characteristics of early abdominal ectopic pregnancy

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives To compare clinical and sonographic characteristics of first‐trimester abdominal ectopic pregnancy (AEP) with those of tubal ectopic pregnancy (TEP), and to define ultrasound‐based diagnostic criteria for AEP. Methods This was a retrospective case–control study comparing cases of AEP diagnosed at four centers with controls diagnosed

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

open access: yesVeterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.

Individualism Without Individuality: Friedrich Hayek and the Neoliberal Citizen

open access: yesConstellations, EarlyView.
ABSTRACT Critics of neoliberalism increasingly examine its corrosive effects on democracy. Scholars often turn to Friedrich Hayek's political theory, arguing that it produces citizens who passively conform to spontaneous social orders. Yet insufficient attention has been paid to the normative conception of the human individual underlying his ...

Divine Self‐Placement, Sacred Placemaking: The Virgin of El Rocío and Territorial Custodianship in Early Modern Spain

open access: yesJournal of Religious History, EarlyView.
This essay argues that the Rocío hallazgo legend employs divine self‐placement to turn territorial uncertainty into sacred stewardship. The Virgin's miraculous refusal to move establishes the marshlands of Las Rocinas as a communal religious site, transforming a marginal and legally ambiguous area.
