Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

Structural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Light transmittance through resin-matrix composite onlays adhered to resin-matrix cements or flowable composites

Journal of the Mechanical Behavior of Biomedical Materials
The aim of this study was to evaluate the influence of the thickness of resin-matrix composite blocks manufactured by CAD-CAM on the light transmittance towards different resin-matrix cements or flowable composites.Sixty specimens of resin-matrix composite CAD-CAM blocks reinforced with 89 wt% inorganic fillers were cross-sectioned with 2 or 3 mm ...

A Randomised Controlled Trial Comparing a One‐Piece Zirconia Tissue‐Level Implant and Two‐Piece Titanium Bone‐Level Implant for Maxillary Single Tooth Replacement—3 year Results

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This RCT evaluated and compared the clinical performance of zirconia and titanium dental implants placed in the maxillary premolar region. Outcomes were assessed 3 years after prosthetic loading and included marginal bone level (MBL) changes, clinical parameters, aesthetic outcomes, and patient related outcome measures (PROMs ...

Effect of Implant Design on Fracture Resistance, Mode, and Crystal Structure of One‐ and Two‐Piece Zirconia Implants With Ceramic or Titanium Abutment Screws: An In Vitro Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the fracture resistance, fracture modes, and crystalline phase changes of zirconia one‐piece implants (OPI) and bone‐level (BLTPI) or tissue‐level, two‐piece implants (TLTPI), with ceramic (C) or titanium (T) abutment screws after dynamic preloading in a moist environment.

Occupational Contact Allergy to Components of Epoxy Resin Systems: Descriptive and Comparative Epidemiological Analyses Based on IVDK Data 2008–2022

Contact Dermatitis, EarlyView.
This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

Adhesion of Newly Developed Composite Resin Splinting Materials to Enamel: Effect of Enamel Surface Treatment

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim To evaluate the shear bond strength (SBS) of newly developed composite resin materials intended for dental splinting to enamel and to determine whether phosphoric acid etching alone provides reliable adhesion. Material and Methods Four experimental materials (G‐Fix, Light Fix, Ortho Connect, and Ortho Connect Flow) were compared
