Novel ionic liquid-infused PVA-based anion exchange membranes boosting bioelectricity yield from microbial fuel cells.

The goal of this research is to develop and characterize low-cost NHI doped polyvinyl alcohol (PVA)-4-ethyl-4-methylmorpholiniumbromide (ionic liquid) anion exchange membranes (AEM) and its application for membrane cathode assembly. Physical characterization like FTIR, POM, and XRD notified the functional groups, basic structure, and amorphosity of the produced membrane, and it was employed in single-chambered microbial fuel cells (sMFCs) as a separator. The membranes in terms of oxygen diffusion, proton conductivity, and ion exchange capabilities were evaluated.

Insights into parental perspectives: Children's eye care in Saudi Arabia.

Purpose: Despite the concerning growth in the number of children with preventable or treatable causes of blindness, parents and/or children often do not notice many eye problems due to the lack of adequate knowledge about them. Considering the lack of updated relevant literature on this topic, this study aimed to gain insights into parental perspectives regarding children's eye health and the barriers that prevent them from promptly addressing these issues.

Methods: A cross-sectional online survey was randomly distributed to Saudi parents of children aged 0-18 years from February 2022 to April 2022.

Optimizing Linezolid: Transforming It into a Selective MAO-B Inhibitor via a Toxicity-to-Activity Optimization Approach.

Linezolid, a widely used oxazolidinone antibiotic, exhibits potent activity against resistant bacterial infections but is associated with serotonergic toxicity, primarily due to its inhibition of monoamine oxidase (MAO). MAOs, consisting of MAO-A and MAO-B isoforms, play crucial roles in neurotransmitter metabolism, with implications for neurodegenerative disorders like Parkinson's and Alzheimer's diseases. This study aims to optimize Linezolid's structure to transform it into a selective MAO-B inhibitor.

Lilobot: A Cognitive Conversational Agent to Train Counsellors at Children's Helplines : Design and Initial Evaluation.

To equip new counsellors at a Dutch child helpline with the needed counselling skills, the helpline uses role-playing, a form of learning through simulation in which one counsellor-in-training portrays a child seeking help and the other portrays a counsellor. However, this process is time-intensive and logistically challenging-issues that a conversational agent could help address. In this paper, we propose an initial design for a computer agent that acts as a child help-seeker to be used in a role-play setting.
