An Investigation of Efficiency Issues in a Low-Pressure Steam Turbine Using Neural Modelling.

This study utilizes neural networks to detect and locate thermal anomalies in low-pressure steam turbines, some of which experienced a drop in efficiency. Standard approaches relying on expert knowledge or statistical methods struggled to identify the anomalous steam line due to difficulty in capturing nonlinear and weak relations in the presence of linear and strong ones. In this research, some inputs that linearly relate to outputs have been intentionally neglected.

Valeriana officinalis root extracts have potent anxiolytic effects in laboratory rats.

Valerian root (Valeriana officinalis) is a popular and widely available herbal supplement, primarily used to treat insomnia and anxiety. Until recently, its mechanism of action has remained unknown. Neurobiological research has begun to show that the herb, with its active valerenic acid, interacts with the GABA(A)-ergic system, a mechanism of action similar to the benzodiazepine drugs.
