Dietary Selection Pressures and Their Impact on the Gut Microbiome [PDF]
Cellular and Molecular Gastroenterology and Hepatology, 2022 The human gut microbiota harbors a heterogeneous and dynamic community of microorganisms that coexist with the host to exert a marked influence on human physiology and health. Throughout the lifespan, diet can shape the composition and diversity of the members of the gut microbiota by determining the microorganisms that will colonize, persist, or ...

Engineering Applications of Computational Fluid Mechanics, 2022 This research describes the dynamic behavior of an isolated slug driven by pressurized air in a voided line with an end orifice. A three-dimensional (3D) computational-fluid-dynamics (CFD) model is used to simulate the rapid propulsion and impact at the ...

Pressure Sensor Drifts in Argo and Their Impacts [PDF]
Journal of Atmospheric and Oceanic Technology, 2011 Abstract In recent years, autonomous profiling floats have become the prime component of the in situ ocean observing system through the implementation of the Argo program. These data are now the dominant input to estimates of the evolution of the global ocean heat content and associated thermosteric sea level rise.
