Structural testing and analytical model of Reinforced Concrete (RC) prisms with 3D‐printed concrete permanent formwork under compressive loading

Structural Concrete, EarlyView.
Abstract The implementation of traditional steel reinforcement in 3D concrete printed structures is a major challenge. Although 3D‐printed structures may be used as formwork, the knowledge about their structural contribution is limited. This research aims to experimentally evaluate the structural performance of reinforced concrete prisms with 3D ...

Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

Seismic Performance of Concrete Square Column Confined by Five-Spiral Composite Stirrups

In order to solve the problem of inadequate confinement provided by traditional rectangular stirrups in concrete square columns under stringent seismic fortification requirements, a spiral stirrup with a better constraint effect was used in the square ...

Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Numerical investigation of the behavior of concrete beams reinforced with FRP polymer stirrups in the form of straps

In reinforced concrete structures that are in corrosive environmental conditions, there is always a discussion of reinforcement corrosion. Therefore, because of the smaller diameter compared to longitudinal rebars and closer to the surface and ...

Anatomical Characteristics of the Facial Nerve in Patients With Cochlear Hypoplasia

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To quantitatively characterize the spatial relationships between intratemporal facial nerve segments and key cochlear implantation (CI) landmarks in cochlear hypoplasia (CH), and to compare these features with age‐matched CI recipients with normal inner ear anatomy, thereby informing preoperative planning and facial nerve ...

Toward implementation of lactate compared with pH in fetal scalp blood sampling during labor: A clinical comparative single‐center study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Lactate and pH in fetal blood samples are moderately correlated (r = −0.53). For the StatStrip® Lactate 2, we propose a lactate cutoff value of ≥5.6 mmol/L based on the most optimal balance between sensitivity (78.1% [60.0–90.7%]) and specificity (79.2% [73.4–84.3%]).
