In-Process Machining Distortion Prediction Method Based on Bulk Residual Stresses Estimation from Reduced Layer Removal
(MDPI, 2024-01-03)
Manufacturing structural monolithic components for the aerospace market often involves machining distortion, which entails high costs and material and energy waste in industry. Despite the development of distortion calculation ...
Fatigue Life Estimation Model of Repaired Components with the Expanded Stop-Hole Technique
(MDPI, 2024-02-01)
Fatigue crack growth tests are conducted to assess the efficacy of the stop-hole crack repair method. This straightforward and widely adopted technique involves drilling a hole at the crack tip and subsequently enlarging ...
Examining the Effect of Freezing Temperatures on the Survival Rate of Micro-Encapsulated Probiotic Lactobacillus acidophilus LA5 Using the Flash Freeze-Drying (FFD) Strategy
(MDPI, 2024-03-01)
This work proposes a novel drying method suitable for probiotic bacteria, called flash freeze-drying (FFD), which consists of a cyclic variation in pressure (up-down) in a very short time and is applied during primary ...
Indirect Adaptive Control Using Neural Network and Discrete Extended Kalman Filter for Wheeled Mobile Robot
(MDPI, 2024-01-30)
This paper presents a novel approach to address the challenges associated with the trajectory tracking control of wheeled mobile robots (WMRs). The proposed control approach is based on an indirect adaptive control PID ...
Membrane Interaction Characteristics of the RTX Toxins and the Cholesterol-Dependence of Their Cytolytic/Cytotoxic Activity
(MDPI, 2024-03-08)
RTX toxins are important virulence factors produced by a wide range of Gram-negative bacteria. They are secreted as water-soluble proteins that are able to bind to the host cell membrane and insert hydrophobic segments ...
Emotions of Educators Conducting Emergency Remote Teaching during COVID-19 Confinement
(MDPI, 2024-02-08)
The home confinement of the population in Spain caused by the COVID-19 pandemic interrupted face-to-face teaching and led teachers of all educational levels to perform their activities remotely. This represented a radical ...
Toxicogenomics of the Freshwater Oligochaete, Tubifex tubifex (Annelida, Clitellata), in Acute Water-Only Exposure to Arsenic
(MDPI, 2024-03-16)
A toxicogenomic approach was used for toxicity evaluation of arsenic in the aquatic environment, and differential gene expression was investigated from 24 h and 96 h water-only acute toxicity tests with the aquatic ...
URB447 Is Neuroprotective in Both Male and Female Rats after Neonatal Hypoxia–Ischemia and Enhances Neurogenesis in Females
(MDPI, 2024-01-28)
The need for new and effective treatments for neonates suffering from hypoxia–ischemia is urgent, as the only implemented therapy in clinics is therapeutic hypothermia, only effective in 50% of cases. Cannabinoids ...
Valorisation of Sub-Products from Pyrolysis of Carbon Fibre-Reinforced Plastic Waste: Catalytic Recovery of Chemicals from Liquid and Gas Phases
(MDPI, 2024-02-21)
Waste carbon fibre-reinforced plastics were recycled by pyrolysis followed by a thermo-catalytic treatment in order to achieve both fibre and resin recovery. The conventional pyrolysis of this waste produced unusable gas ...
The Influence of Lipid Electric Charge on the Binding of Aβ(1–42) Amyloid Peptide to Bilayers in the Liquid-Ordered State
(MDPI, 2024-03-01)
The amyloidogenic Aβ peptides are widely considered as a pathogenic agent in Alzheimer’s disease. Aβ(1-42) would form aggregates of amyloid fibrils on the neuron plasma membranes, thus perturbing neuronal functionality. ...
