An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Production of recombinant human granulocyte‐macrophage colony‐stimulating factor in thermoinducible E. coli: Tuning inclusion body architecture and protein yield via dissolved oxygen control

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Recombinant protein expression in Escherichia coli frequently results in the formation of inclusion bodies (IBs), which provide high protein accumulation but often require additional steps to recover functional protein. Although culture conditions strongly influence IB physicochemical and structural characteristics, the impact of ...

Posthumanism and Cybernetic Art: An Esthetic Exploration of Technology and Human Identity

Sociology Lens, EarlyView.
ABSTRACT Posthumanism is a contemporary intellectual movement that redefines the relationship between humans, technology, biology, and culture. While questioning the traditional humanist perspective that places humans at the center of the universe, it also examines the transformative effects of technology on human identity.

Physiological and Sleep Profiles in Insomnia, OSA and COMISA: A Comparative Study in Portugal and Spain

Journal of Sleep Research, EarlyView.
ABSTRACT Insomnia and obstructive sleep apnea (OSA) are common sleep disorders that often co‐occur as comorbid insomnia and sleep apnea (COMISA), worsening health outcomes. This study characterized and compared the physiological and sleep profiles of insomnia, OSA and COMISA in population‐based datasets from Portugal (n = 147) and Spain (n = 264 ...

Sundman‐Like Transformations and the NRT Nonlinear Schrödinger Equation

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14791-14810, 15 September 2026.
ABSTRACT We present a new generalization of the well‐known power‐type Sundman transformation, involving not only powers of the function but also of its derivative, along with its inverse. Our aim is to explore the use of such transformations in the derivation of solutions of ordinary differential equations and in the study of their properties.
