Piezoresistive response of carbon nanotube and carbon fiber/epoxy composites under cyclic loading (2023)

Maintaining the mechanical properties and long-term operational safety is considered the main challenge for composite materials under cyclic loading. This work presents mechanical performance of tri-component composites based on multiwall carbon nanotubes (MWCNTs), carbon fibres (CFs) and epoxy resin, and their electrical conductance property for applications like strain gauges. As a result of incorporation of MWCNTs into the epoxy resin in the composite’s morphology, their electrical, mechanic

Experimental Investigation of the Fatigue Behavior of Fiber-Reinforced Composites under Cyclic Loading Conditions (2024)

The research presented here aims to conduct a performance assessment of fiber-reinforced composites (FRC) under cyclic loading with emphasis on Glass fiber-reinforced polymer (GFRP) & Carbon fiber-reinforced polymers (CFRP). FRCs’ use in engineering applications is occasioned by the high strength-to-weight ratios despite the poor performance under cyclic loads. In the experiments conducted CFRP was found to more than double the fatigue life for similar applied stress compared to GFRP. The st

Genetic Risk Factors for Postoperative Atrial Fibrillation – a Nationwide Genome-Wide Association Study (GWAS) (2022)

Abstract Background Atrial fibrillation (AF) is a major cause of morbidity with a high prevalence among the elderly and has an established genetic disposition. Surgery is a well-known risk factor for AF; however, it is currently not recognized how much common genetic variants influence the postoperative risk. The purpose of this study was to identify Single Nucleotide Polymorphisms associated with postoperative AF.

Genome-wide association studies (GWAS) for orthopedic diseases: a systematic review (2023)

Background and Objective: The objective of this review is to examine genome-wide association studies (GWAS) and whether they have helped treat orthopedic diseases in general and in the Middle East in particular. Methods: Between 2005 and May 2022, we searched MEDLINE, Scopus, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials and Cochrane Database of Systemat

deMeta: Removing sub-studies from meta-analysis of genome wide association studies (GWAS) (2020)

ABSTRACT Summary Post-GWAS studies using the results from large consortium meta-analysis often need to correctly take care of the overlapping sample issue. The gold standard approach for resolving this issue is to reperform the GWAS or meta-analysis excluding the overlapped participants. However, such approach is time-consuming and, sometimes, restricted by the available data. deMeta

Power from the People (2023)

Maritime archaeologists have long recognized the value of volunteers to further research and management goals. Opportunities in maritime archaeological training, research, and fieldwork are growing for non-divers as well as those certified to scuba dive, and archaeologists generally are grateful to work with anyone who wants to learn more about and engage with maritime cultural heritage. Anyone with an interest in our maritime past may be enlisted as citizen scientists because not everything mar
