Reaction Mechanisms During Co2 Absorption In Ethanolamine Solutions, Teng Weiwei, Wu Yan, Fan Yuxin, Liao Tao, Wang Zicheng, Yu Hui, Li Meng, Xu Xiaoling

Coal Geology & Exploration

Objective Presently, CO2 capture technology based on the ethanolamine solutions suffers from drawbacks such as high energy consumption and elevated costs. A primary method to address these challenges is to construct blended amine solutions by synergistically integrating the absorption and desorption advantages of different types of ethanolamines. Hydroxyethyl ethylenediamine (AEEA) and N-methyldiethanolamine (MDEA) represent two major commonly used absorbents, and their blending necessitates an accurate understanding of their CO2 absorption patterns, including CO2 loading capacity, the ion-concentration distribution patterns of reaction products, and reaction orders. Currently, their absorption mechanisms remain poorly understood, and there is a lack …

Electoral Due Process, Michael S. Kang Jan 2026

Electoral Due Process, Michael S. Kang

Northwestern University Law Review

Hyperpartisanship has hit century-long highs in American politics and is emboldening state government attempts to undermine election outcomes by using control over state lawmaking structure to strip away authority, and sometimes outright unseat, partisan opponents after they win elected office. Even as traditional norms against such moves have eroded, the Supreme Court has taken a pro-partisanship turn in removing judicial checks against such moves under equal protection and constitutional structure. This Article proposes shifting from challenges under those doctrines to a new approach under electoral due process for confronting this new generation of antidemocracy. Federal due process law restricts the …

Insomnia, The Witch, And The Dark Passenger As Shadow Projections In Joharah Al-Remal's Al-Awsaj, Dr. Afaf Al-Enezi Jan 2026

Insomnia, The Witch, And The Dark Passenger As Shadow Projections In Joharah Al-Remal's Al-Awsaj, Dr. Afaf Al-Enezi

Journal of Arabic Sciences and Humanities

This study investigates how psychic repression and identity fragmentation are represented in Joharah Alremal’s Al-Awsaj (2023), asking how inherited trauma and the symbolic Dark Passenger shape the protagonist’s fractured selfhood. It aims to clarify the mechanisms through which insomnia, shadow projection, and the witch’s prophecies externalize unresolved familial wounds. Methodologically, the paper employs a psychoanalytic close reading informed by Jungian theory, situating the novel in comparative dialogue with Jeff Lindsay’s Darkly Dreaming Dexter (2004). The comparison examines both the universality of repressed destructive impulses and cultural trauma specific forms through which trauma manifests. The study finds that negotiations with the …

Semiological Analysis Of Visual Representations Of The Female Body On Instagram, Hassan Baha Jan 2026

Semiological Analysis Of Visual Representations Of The Female Body On Instagram, Hassan Baha

Faits de Langue et Société (FLS)

On digital social networks and Instagram in particular, female influencers mainly use images to communicate with their audience. A form of visual communication that allows them to enter a process of digital self-presentation. On Instagram, the female influencers in our sample are depicted as perfect, slim body and attractive. These images can impact women's perception of their own bodies and self-worth. A visual/virtual representation that can encourage women to seek an unrealistic physical perfection maintaining, in order to achieve this ideal, a set of stereotypes that persist in the social imaginary. In this present project, we will study the images …
