Review on Vibration Problems in Turbomachinery
Abstract: Vibration suppression of turbomachinery is an important engineering problem. Vibration caused by mass imbalance is a common problem in rotating the turbomachinery systems. Imbalance occurs if the principal axis of inertia of the rotor is not coincident with its geometric axis. Higher speeds cause much greater centrifugal imbalance forces, and the current trend of rotating equipment toward higher power density clearly leads to higher operational speeds. In this paper, a …

Cryogenic Electron Microscopy Reveals Conformational Dynamics and Catalytic Mechanisms of Human Fatty Acid Synthase in De Novo Lipid Biosynthesis
Abstract: Fatty acid synthase (FASN) is a multifunctional homodimeric enzyme central to de novo fatty acid synthesis in mammals. Recent cryogenic electron microscopy (cryo-EM) studies have illuminated the structural basis of FASN catalysis, revealing multiple conformational states throughout the synthesis cycle. These findings show that the acyl carrier protein (ACP) domain dynamically shuttles substrates between spatially separated active sites, while the condensing and modifying regions remain structurally stable. In contrast to …

Entropy-Based Damage Accumulation in Tribological Systems: A Comprehensive Review
Abstract: This paper reviews classical wear models and entropy-based degradation approaches used for predicting failure in tribological systems. Various wear models, thermodynamic frameworks, and applications of the Degradation Entropy Generation (DEG) theorem are discussed. Friction, which is the primary source of heat generation in tribological contacts, is responsible for material degradation through a variety of irreversible processes. While classical wear approaches have been widely used for wear prediction and life estimation, …
