Heritage without people, heritage without time: The preservation paradigm in contemporary Egypt

This article situates the current Egyptian regime’s de facto rejection of adaptive reuse or participatory preservation projects within the lineage of colonial notions of heritage. Much like its colonial predecessors, the regime deals with heritage as its private property, deployi...

Wounds that parent: Emotion regulation difficulties as pathways for the intergenerational continuity of harsh discipline

Background Harsh discipline (HD) remains common across cultural contexts and is often transmitted intergenerationally. However, the mechanisms underlying this continuity remain underexplored in non-Western contexts. Objective This study examined whether parents' recollections of...

Green synthesis of CuO nanoparticles using mangrove leaves for targeted delivery of platinum (II) therapeutics

Abstract Copper oxide nanoparticles (CuO NPs) synthesized via green chemistry using Avicennia marina mangrove leaf extract represent an environmentally sustainable approach to generating biocompatible nanomaterials for pharmaceutical applications. This study utilized the phytoche...

Nano-enabled delivery of natural products and combinatorial chemotherapy for triple-negative breast cancers: mechanisms, synergy, and translational challenges

Among breast cancer subtypes, Triple-negative breast cancer (TNBC) is recognized for its aggressive behavior and is characterized by the absence of hormone receptors (estrogen and progesterone) and HER2 overexpression. This absence results in fewer treatment options and less favo...

The Corrupted Save File: A Poster Series on Data Loss Stories

What did you lose? A wedding photo album when a hard drive failed. Ten years of emails when a provider shut down. A novel draft, half-finished, to a corrupted USB stick. A child's first words, recorded on a phone that never synced. These stories are everywhere—yet rarely spoken a...

Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

CatalyticPerformance and Reaction Mechanism of Coand Zn-Codoped Fe Catalysts on Different Supports for CO2 Hydrogenation

Abstract Metal oxides are commonly used as supports for catalysts for CO2 hydrogenation. However, systematic studies on the influence of different metal oxide supports on the catalytic performance of catalysts for light olefin production remain limited. Therefore, a series of cob...
