Study on damage deterioration law of slate under the action of freeze-thaw cycle

Meikuang Anquan
Aiming at the problem of damage and deterioration of slate on the slopes of open-pit mines in cold regions under freeze-thaw conditions, various types of slate samples from a typical open-pit mine in Inner Mongolia were subjected to laboratory tests ...

Study on mechanical properties and air-void structure characteristics of hybrid fiber fly ash concrete under sulfate attack

Materials Research Express, 2021
Sulfate attack is one of the common durability problems of concrete. The concrete structure in saline soil is particularly susceptible to sulfate attack. The aim of this paper was to investigate the effect of fly ash on the mechanical properties and pore

Fracture mode of glass plate subject to low-velocity impact: experimental investigation and finite element simulation

Mechanical Engineering Journal, 2019
An understanding of the impact response of glass plates is important to protect people from injury. We investigated the fracture mode of a float glass plate that fractured under a low-velocity impact and conducted a numerical simulation. First, an impact

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Constitutive Modeling and Numerical Simulation of Frp Confined Concrete Specimens

Slovak Journal of Civil Engineering, 2014
Fiber-reinforced polymer (FRP) composites are generally used for the seismic retrofit of concrete members to enhance their strength and ductility. In the present work, the confining effect of Carbon Fiber-Reinforced Polymer (CFRP) composite layers has ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...
