Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

Small, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

A Cytoplasmic pH Sensor Redefines Gating in Bacterial Urea Channels and Acid Resistance

Small, EarlyView.
Bacterial survival in acidic environments requires pH‐gated urea channels. Utilizing complementary approaches, we identify a conserved cytoplasmic glutamic acid residue as a pH sensor in UreI channels. Whereas Gram‐positive bacteria rely solely on this sensor, Gram‐negative bacteria employ a dual‐sensor mechanism with periplasmic residues, revealing a ...

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

steel 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

steel 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

Safety 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.

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

Veterinary 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.

The Fibula Free Flap as Used for Reconstruction in Patients With Oral Cavity Malignancy: A Systematic Review

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives The fibula free flap is a widely used means of reconstructing the maxilla and mandible. It is used for a variety of indications, including for reconstruction after resection of a benign or malignant tumor, osteoradionecrosis, or trauma.

Individualism Without Individuality: Friedrich Hayek and the Neoliberal Citizen

Constellations, 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

Journal 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.

Syphilis and ‘Sons of Empire’: The ‘Prostitute’ and Britain's Fighting Arm in Nineteenth ̵ Century Colonial Punjab

Gender &History, EarlyView.
ABSTRACT The British army in India took great care to provide European troops with facilities for sexual relations while anxiously managing venereal disease. Examining archival evidence, political debates and medical discourse from the nineteenth century, this article examines the colonial military enterprise of regulated prostitution in colonial ...
