Ultrasonic Characterization of Nickel-Chromium-Base Anticorrosive Coatings

One of the most important applications of anticorrosive coatings is the protection of structural components of conventional power generating plants. In particular, nickel- chromium based coatings have been used at the Instituto de Investigaciones Eléctricas in México for their application in boiler tubes and turbine blades of power plants [1]. However, there are not well-established NDE methods to characterize the bonding between the metal base and the coating.</p

A New Automated System for Boreside Ultrasonic Inspection of Power Plant Turbine Rotors

Among the concerns of the electric power generation industry is that related to the structural integrity of their equipment; in particular, the turbine due to the involved costs in case of failure. Although different parts of a turbine may fail, the rotor is the component to care about since, on one hand, it is subject to large stresses and, on the other, its failure may lead to severe damages; therefore, various tools have been developed to provide information for its safe operation [1].</p

Electrostatic Fermentation: Molecular Response Insights for Tailored Beer Production

Electrostatic fermentation avoids the cellular redox imbalance of traditional fermentation, but knowledge gaps exist. This study explores the impact of electrostatic fermentation on the growth, volatile profile, and genetic response of Saccharomyces pastorianus Saflager S-23. The applied voltage (15 and 30 V) in the electrostatic fermentation system increased the growth and substrate utilization of S. pastorianus while decreasing ethanol production. The aromas typically associated with traditional fermentation, such as alcoholic, grape, apple, and sweet notes, were diminished, while aromas like roses, fruits, flowers, and bananas were augmented in electrostatic fermentation. RNA-seq analysis revealed upregulation of genes involved in cell wall structure, oxidoreductase activity, and iron ion binding, while genes associated with protein synthesis, growth control, homeostasis, and membrane function were downregulated under the influence of applied voltage. The electrostatic fermentation system modulates genetic responses and metabolic pathways in yeast, rendering it a promising method for tailored beer production. Demonstrating feasibility under industrial-scale and realistic conditions is crucial for advancing towards commercialization

Social and Structural Challenges to Drug Cessation Among Couples in Northern Mexico: Implications for Drug Treatment in Underserved Communities

BACKGROUND: Available drug treatment modalities may inadequately address social and structural contexts surrounding recovery efforts. METHODS: This mixed methods analysis drew on (1) surveys with female sex workers and their intimate male partners and (2) semi-structured interviews with a subsample of 41 couples (n = 82 individuals, 123 total interviews) in Northern Mexico. Descriptive and content analyses examined drug cessation and treatment experiences. RESULTS: Perceived need for drug treatment was high, yet only 35% had ever accessed services. Financial and institutional barriers (childcare needs, sex-segregated facilities) prevented partners from enrolling in residential programs together or simultaneously, leading to self-treatment attempts. Outpatient methadone was experienced more positively, yet financial constraints limited access and treatment duration. Relapse was common, particularly when one partner enrolled alone while the other continued using drugs. CONCLUSIONS: Affordable, accessible, evidence-based drug treatment and recovery services that acknowledge social and structural contexts surrounding recovery are urgently needed for drug-involved couples
