“…22,23 High salt content reduces the efficiency of conditioners, while high organic content increases the viscosity of the digestate, complicating the dewatering process. 24,25 Although some studies have shown that advanced oxidation 26 and hydrothermal 27 conditioning methods can improve the dewatering performance of food waste digestate, the applicability and efficiency of these techniques, primarily developed for municipal sludge dewatering, have not been fully validated for food waste digestate. 4,6 Therefore, there is an urgent need for focused research on the deep-watering of food waste digestate.…”

“…30,28 Given the high salt and organic content of food waste digestate, conditioning methods based on skeleton construction are more suitable for its deep dewatering. 25 Industrial-grade composite basic aluminum chloride (BAC) with its high charge density and stable alumina network structure, effectively promotes flocculation and forms a skeletal structure conducive to pressure transmission. 31 These properties make BAC an excellent alternative to quicklime, offering superior dewatering performance and environmental benefits.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
