A gut microbiome‐lipid axis in early pregnancy is associated with metabolic dysregulation and diabetes risk

iMeta, EarlyView.
Early‐pregnancy microbiome and lipidome profiling identified a microbiome‐glycosphingolipid axis associated with later gestational diabetes mellitus (GDM) risk. In the prospective pregnancy cohort, women who later developed GDM showed altered gut microbial composition, enriched microbial lipid biosynthesis pathways, and broad plasma lipidomic changes ...

Power Swing Generated in Francis Turbines by Part Load and Overload Instabilities

Energies, 2017
Hydropower plays a key role in the actual energy market due to its fast response and regulation capacity. In that way, hydraulic turbines are increasingly demanded to work at off-design conditions, where complex flow patterns and cavitation appear ...

Experimental investigation of pressure fluctuations caused by a vortex rope in a draft tube

IOP Conference Series: Earth and Environmental Science, 2012
In the last years hydro power plants have taken the task of power-frequency control for the electrical grid. Therefore turbines in storage hydro power plants often operate outside their optimum. If Francis-turbines and pump-turbines operate at off-design conditions, a vortex rope in the draft tube can develop.

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...
