Computational Mechanics Model to Evaluate the Structural Maintenance of Catenated Hydrogen‐Bonded Organic Frameworks

open access: yesSmall, EarlyView.
This study presents a computational framework treating crystalline HOFs as adaptive atomic‐scale interfaces. Catenated HOFs preserve lattice stability under load while enabling auxetic deformation and reversible nonlinearity. The results provide direct evidence that supramolecular interactions govern macroscopic resilience and structural adaptability ...

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

open access: yessteel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Design of finger milling cutter for precision machining of involute internal herringbone gear with short relief groove

open access: yesJixie chuandong
ObjectiveConventional disc-shaped milling cutters create excessively large relief grooves when machining internal herringbone gears, limiting their applicability, while finger milling cutters based on a simplified normal plane of the tooth space suffer ...

Opportunities for the Labour Party: Football, Class and Community Renewal

open access: yesThe Political Quarterly, EarlyView.
Abstract This article argues that football represents an underutilised opportunity for the Labour Party to anchor a wider programme of civic renewal. In many working‐class communities, the decline of trade unions, working men's clubs and other associational spaces has eroded collective life, leaving football clubs as rare institutions where dignity ...

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Short‐Term Surgical Outcomes: Modified Dorsal Inlay Graft Versus Tubularized Incised Plate Urethroplasty in Pediatric Hypospadias With Narrow Urethral Plates

open access: yesAndrology, EarlyView.
ABSTRACT Background Reconstructing the urethra presents in hypospadias surgery is difficult. Occasionally, the urethral plate (UP) may be quite narrow, necessitating augmentation or replacement to achieve additional tubularization. Objective The objective of this research was to assess the application of modified dorsal inlay graft (mDIG) and ...

Supporting Children With a Chronic Disease and Their Parents When Admitted to Hospital: A Scoping Review of Psychosocial Supports

open access: yesActa Paediatrica, EarlyView.
Importance of psychosocial support. ABSTRACT Aim The aim of this scoping review was to identify, examine, and summarize available evidence regarding psychosocial supports provided to children with a chronic disease when admitted to hospital and their parents. Method The JBI methodology for conducting and reporting scoping reviews was followed.

NUMERICAL STUDY OF GRADUAL CHANGE IN SHAFT DIAMETER AND RELIEF GROOVE RADIUS ON STRESS CONCENTRATION FACTOR

open access: yesEurasian Physical Technical Journal
The purpose of this work is to investigate the effect of relief groove radius and the taper in gradual diameter change of shaft on stress concentration factors. Finite element analysis was used to conduct theoretical research in order to reduce the maximum value of stress in stepped shafts. In comparison based on a straight shaft without relief groove,

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

open access: yesArchaeometry, EarlyView.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.
