Article Synopsis
- Real-time monitoring of early-age concrete strength using advanced nano-enhanced sensors is crucial for preventing unexpected fractures and ensuring structural integrity.
- This study introduces a hybrid method (NDT-LSTMs-ANN) that combines Non-Destructive Testing techniques with machine learning models to predict concrete strength based on various factors like water-to-cement ratio, temperature, and curing time.
- The results indicate that using piezoelectric-based electro-mechanical impedance technology with these advanced sensors significantly improves concrete strength estimation and enhances safety and efficiency in construction.
Article Synopsis
- - The study aimed to explore how statin use affects the severity of COVID-19 in hospitalized patients at a hospital in Riyadh from July to September 2020.
- - Researchers analyzed data from 689 COVID-19 patients, finding that a significant portion had comorbidities like hypertension and diabetes, and 155 used statins during their hospital stay.
- - Results indicated that patients on statins had higher risks of ICU admission, intubation, complications, and mortality compared to those not taking statins.
Presently, the main cause of pollution of natural water resources is heavy metal ions. The removal of metal ions such as nickel (Ni) and cadmium (Cd) has been given considerable attention due to their health and environmental risks. In this regard, for wastewater treatment containing heavy metal ions, graphene oxide (GO) nanocomposites with metal oxide nanoparticles (NPs) attained significant importance.

Methods: The buccal surface of 84 extracted maxillary premolars was grounded to create flat surface. The specimens were allocated into 3 groups (n = 28) depending upon the adhesive systems, then each group was divided into two sub-group (I, II) (n = 14).
