Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

open access: yesStructural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.

Image Restoration Algorithm and Propagation Mechanism of Partial Discharge Streamer in Oil–Pressboard Insulation Needle–Plate Electrode

open access: yesHigh Voltage, EarlyView.
ABSTRACT Oil–pressboard system is the main insulation form of oil‐immersed transformers, which is prone to partial discharge (PD) and subsequent faults due to contamination or moisture ingress. To investigate the evolutionary characteristics of PD streamers under varying voltages and insulation dimensions, streamer images were captured using a high ...

The Effect of Crown Height and Retentive Height of Abutment on the Fracture Resistance of Fatigued Monolithic Zirconia Anterior Implant Crowns—An In Vitro Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This laboratory study investigated the effect of two different retentive heights of Ti‐base abutments (3.5 and 5.5 mm) and crown heights (13 and 16 mm) on the load at failure and survival of monolithic zirconia implant‐supported crowns replacing a maxillary central incisor.
