Novel Ultrafiltration Polyethersulfone Membranes Blended with Carrageenan.

The development of ultrafiltration (UF) polymeric membranes with high flux and enhanced antifouling properties bridges a critical gap in the polymeric membrane fabrication research field. In the present work, the preparation of novel PES membranes incorporated with carrageenan (CAR), which is a natural polymer derived from edible red seaweed, is reported for the first time. The PES/CAR membranes were prepared by using the nonsolvent-induced phase separation (NIPS) method at 0.

Nickel removal from synthetic wastewater by novel zeolite-doped magnesium- iron- and zinc-oxide nanocomposites by hydrothermal-calcination technique.

This study aims to modify raw zeolite with metal oxide nanocomposites to remove nickel (Ni) ions from synthetic wastewater. Novel zeolite-doped magnesium oxide (MgO), iron oxide (FeO), and zinc oxide (ZnO) nanocomposites were synthesized by hydrothermal-calcination methods. The novel zeolite-doped metal oxide nanocomposites were used as adsorbents to remove Ni (II) ions from synthetic wastewater.

Enhancing Special Pathogen Preparedness Through Exercises: Navigating Dual Quarantine Activations.

This case study describes findings from an exercise conducted in April 2023 to assess the readiness of the National Quarantine Unit (NQU) and identify opportunities for improvement. The exercise is part of a multiyear effort to assess the readiness of quarantine and transport capabilities at the NQU through annual workshops, discussion-based exercises, and functional and full-scale exercises. The April 2023 exercise tested interagency coordination and decisionmaking, transport of individuals for monitoring, quarantine unit operations, and escalation of care for symptomatic individuals out of quarantine to high-level isolation units in the United States.

Neighborhood assets, parenting, and child disruptive behavior in low-income Black families.

Neighborhood assets, such as access to recreational facilities, density of residence, and safety, were examined in relation to parenting and disruptive behavior in early childhood. Examining data from a low-income Black preschool sample, this study investigated how self-reported neighborhood assets and observed parenting behaviors interactively predict observed disruptive behavior in children. Findings revealed a significant relationship between parenting and child behavior, where parenting with high sensitivity and engagement and parenting with less verbal and physical interference and intrusiveness predicted fewer child disruptive behaviors.

Frailties of Memory: Implications for Therapists Treating Gender Dysphoric Youth.

Therapists working with gender-questioning teens often encounter disparate narratives. Teens typically report memories consistent with their transgender identity, often recounting specific childhood events. Many parents, however, have different recollections of their teen's childhood.
