Unexpected pectus carinatum: Reverse bending of xiphisternal joint after modified Nuss procedure

Journal of Pediatric Surgery Case Reports, 2023
The pectus carinatum has been rarely reported as complication after Nuss procedure. The case we present here is that of a 14-year-old Chinese male who underwent modified Nuss procedure to correct pectus excavatum and presented a sudden pectus carinatum ...

Sparkling hot spots in perovskite solar cells under reverse bias

ChemPhysMater, 2022
Perovskite solar cells (PSCs) are attracting much attention and are on the way to commercialization. However, some modules are subject to reverse bias in actual fields, so it is meaningful to investigate the reverse-bias behavior of PSCs.

Study on the Effect of the Water Injection Rate on the Cavern Leaching Strings of Salt Cavern Gas Storages

Energies, 2022
In the early construction of cavern leaching in salt cavern gas storages, the inner leaching tubing is often blocked, frequently leading to the bending deformation phenomenon of the leaching strings, which can result in out-of-control cavity shapes.

A nonlocal sinusoidal shear deformation beam theory with application to bending, buckling, and vibration of nanobeams [PDF]

, 2012
This paper presents a nonlocal sinusoidal shear deformation beam theory for the bending, buckling, and vibration of nanobeams. The present model is capable of capturing both small scale effect and transverse shear deformation effects of nanobeams, and ...

Fatigue analysis on flax-epoxy composites: insights and implications

Acta Polytechnica CTU Proceedings
This study investigates the performance of flax fiber and epoxy resin composites, focusing on fatigue testing, which is scarcely reported in the literature. Fatigue behavior is evaluated under full reverse bending loading conditions: R = −1.

Calculations of the Strains and Thicknesses of Pipe Elbows on the Basis of Expressions Resulting from the EU Directive for the Case of Large Strains

Engineering Transactions, 2015
The relations to calculate the maximum value of relative strains, which occur in a process of bending of tubes on benders, in stretched layers of tubes, are presented in this work on the basis of the EU Directive concerning production of pressure ...

Research on Dynamic Response of Pipeline under the Reeling Process and Laying Process

Journal of Marine Science and Engineering, 2023
During the process of laying submarine pipelines using the R-lay (short for reel-lay) method, the interaction between the pipeline and the laying equipment undergoes continual fluctuations, leading to bending in the pipeline induced by the stochastic ...
