From Semi-Infinite to Thin-Layer Diffusion─Effects of Finite Mass Transport on the Electrochemical Response of Redox Probes: Implications for Electroanalytical Measurements.

Electrochemistry in confined environments, that is, involving experimental configurations with spatial restrictions that affect the overall mass transport, is becoming a very attractive way of carrying out electroanalytical measurements for sensing, especially for the so-called thin-layer (TL) configuration, which ideally allows the complete conversion of the analytes under study in small volumes and short times. To improve the understanding of this kind of situation, general expressions for the current-potential-time and charge-potential-time responses of charge transfer processes taking place under finite diffusion conditions with two different configurations (no mass renovation, bounded diffusion; and effective mass renovation, unbounded diffusion) are discussed in this work. By using these expressions, it is possible to establish accurate limits for the attainment of TL conditions and to conclude that for bounded conditions, the charge is a more adequate quantity for electroanalytical purposes.

Adherence to a telehealth program for older adults with dementia and their caregivers: A mixed-methods study.

The objectives were to analyze the association between the cognitive performance of older adults/caregivers, adherence to a telehealth program and investigate reasons for dropouts, retention and adherence. A mixed-methods study was conducted involving 41 older adults diagnosed with dementia who participated in a 12-week telehealth program that offered physical exercises for the older adults and psychoeducation for the caregivers. Cognitive performance, adherence rates, benefits and reasons for withdrawal, retention and adherence were determined with the aid of questionnaires, field records, and focus groups.

Smart interfaces to assist the operator in the context of industry 4.0 with a 5S human-centric approach.

This paper explores the integration of haptic gloves and virtual reality (VR) environments to enhance industrial training and operational efficiency within the framework of Industry 4.0 and Industry 5.0.

Genomic-Inbreeding Landscape and Selection Signatures in the Polo Argentino Horse Breed.

Analyzing genetic variability and inbreeding trends is essential for effective breed management in animal populations. To this, the characterization of runs of homozygosity (ROH) provides a good genomic approach to study the phenomena. The Polo Argentino (PA) breed, globally recognized as the best adapted to playing polo, is known for its strong influence of Thoroughbreds, intense selective breeding, and extensive use of reproductive biotechnologies.

Ancient DNA Reveals the Earliest Evidence of Sheep Flocks During the Late Fourth and Third Millennia BC in Southern Iberia.

The Spanish Merino is the most significant sheep breed globally due to its economic and cultural importance in human history. It has also had a substantial influence on the development of other Merino and Merino-derived breeds. Historical sources indicate that crossbreeding to produce finer, higher-quality wool was already taking place in the south of the Iberian Peninsula during the Roman era.
