Corrosion of embedded steel liners in nuclear containments threatens structural integrity and is challenging to detect. Acoustic emission (AE) and nonlinear ultrasonic cross-modulation were applied to monitor cracking in a concrete cube with an embedded steel plate under galvanostatic corrosion. AE showed intense early activity from rapid crack initiation. The modulation index (MI) dropped during
Energy efficiency is usually framed as a demand-side concern, yet the pace of renewable expansion increasingly depends on how efficiently supply-side systems integrate new capacity. This paper reframes efficiency as a governance question, examining how policy design, institutional coordination, and planning practices shape system-level efficiency outcomes during the rapid expansion of large-scale
INTRODUCTION: There are currently no colorectal cancer (CRC) screening recommendations specifically outlined for people with HIV (PWH). Screening measures used for people without HIV (PWoH) have been previously discussed as sufficient for use among PWH, despite observations of higher CRC prevalence and CRC reportedly appearing at earlier ages among PWH in comparison to PWoH. Machine learning (ML)
Agroecological approaches harnessing in-field biodiversity have been highlighted as a sustainable way to reduce yield gaps, but long-term assessments of their ability to buffer production from weather extremes and increasing interannual and intraseasonal climate variability are scarce. Here, we analyze a 12-year dataset from 642 control vs. push-pull maize field pairs in western Kenya, where long-
SUMMARY: Measurement errors play a critical role in the reliability of geophysical imaging techniques, particularly in ill-posed and bad conditioned problems such as Electrical Resistivity Tomography (ERT). Experimental errors—such as high contact resistance, low signal levels and electromagnetic interference—can significantly introduce random and coherent noise in measurements. Reciprocal measure
Hypothesis: Crystal properties are essential in determining the functionality of final products in pharmaceutical and food applications. This study hypothesizes that membrane-assisted antisolvent crystallization (MAAC) can regulate supersaturation profiles to influence polymorph selection and crystal growth kinetics in glycine crystallization. By using polyvinylidene fluoride (PVDF) membranes to c
The crystal morphology influences the properties of organic compounds, especially in pharmaceutics such as the dissolution and absorption of drugs in the human cells. In antisolvent crystallization, the crystal size and shape are tied to the degree of mixing and dosage of antisolvent, which could be controlled using membranes with specific morphology/surface properties. Little is known though on t
Antisolvent crystallization is commonly used in the formation of heat-sensitive compounds as it is the case for most active pharmaceutical ingredients. Membranes have the ability to control the antisolvent mass transfer to the reaction medium, providing excellent mixing that inhibits the formation of local supersaturations responsible for the undesired properties of the resulting crystals. Still,
Crystallization faces great challenges from the point of view of technology readiness, process economics, and energy consumption. Membranes are capable of controlling both energy and mass transfer, and they can lead to major improvements if integrated into antisolvent crystallization processes, for example, limiting unfavorable kinetics and thermodynamics that are responsible for undesired crystal
The production of dimethyl carbonate (DMC) from CO2 and methanol (MeOH) is an attractive route for CO2 capture and utilization. In this process, the separation of DMC from the reaction medium is critical to maximize the conversion of CO2. However, DMC and MeOH form an azeotropic mixture that is difficult to separate. This work investigates the possibility of using task-specific ionic liquids (TSIL
With the continuous pressure of water contamination caused by textile industry, loose nanofiltration (LNF) membranes prepared by green materials with an extraordinary water permeability are highly desirable for the recovery and purification of dyes and salts. In this work, low-pressure LNF membranes with ultrahigh permeability were fabricated via one-step interfacial polymerization (IP), in which
The separation of dimethyl carbonate (DMC) –an ecofriendly organic compound– from a reaction medium is oftentimes complicated due to the presence of other organic compounds, particularly when the mixture forms an azeotrope. To this end, pervaporation is proposed in this work as the perfect candidate to solve this separation puzzle, using novel membranes which flipped the ratio of the binary mixtur
Air pollutants, such as particulate matter, are known to contribute to disease in humans, but their impact on wildlife remains understudied. A contributing factor to this health impact is the fraction of inhaled particles depositing in the respiratory system. Compared to humans, birds are equipped with a very different respiratory system, which may render them more or less susceptible to air pollu
The final disappearance of the aurochs (Bos primigenius) from Poland in the 17th century marked the culmination of a decline that had begun as early as the Atlantic period. Although human activities primarily drove its extinction, the reasons for its earlier disappearance in Scandinavia remain uncertain. This study investigates the immigration and extinction dynamics of the Scandinavian aurochs duThe final disappearance of the aurochs (Bos primigenius) from Poland in the 17th century marked the culmination of a decline that had begun as early as the Atlantic period.

Aim: To investigate, analyse, and describe patients’ experiences of self-supervised training with the voice therapy app The Voice Assistant (Swedish: Rösthjälpen). Method: Semi-structured interviews were conducted with 12 participants who completed voice therapy using the app to support continued home training. Interviews were audio-recorded, transcribed, and analysed using systematic text condens
