Abstract Density-wave fronts in a vibrofluidized wet granular layer undergoing a gas-liquid-like transition are investigated experimentally.The threshold of the instability is governed Portable Sinks by the amplitude of the vertical vibrations.Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of the container
Cunninghamia lanceolata (Lamb.) Hook.has been widely planted in subtropical China to meet increasing timber demands, leading to short-rotation practices that deplete soil nutrients.However, increased nitrogen (N) deposition offsets soil N depletion.While long-term experimental data investigating the coupled effects related to short rotation practic
School vandalism is a serious problem as it places a heavy burden on education budgets and can cause teaching and learning to collapse.Learners have the right to be taught in neat, clean school Portable Sinks buildings and grounds, to play and to develop their full potential.It is therefore important to find ways of preventing school vandalism.Agai
Background: Hepatocellular carcinoma (HCC) pathogenesis involves the alteration of multiple liver-specific metabolic pathways.We systematically profiled cancer- and liver-related classes of metabolites in HCC and adjacent liver tissues and applied supervised machine learning to compare their potential yield for HCC biomarkers.Methods: Tumor and cor
