GALACTIC EVOLUTION SHOWING A CONSTANT CIRCULATING SPEED OF STARS IN A GALACTIC DISC WITHOUT REQUIRING DARK MATTER

Galactic Evolution Showing a Constant Circulating Speed of Stars in a Galactic Disc without Requiring Dark Matter

It is an unsolved mystery that the rotation velocity of a galactic disc is same at any radial distances.The presence of dark matter is expected, but not observed.Here we propose a Bodysuit novel scheme for the evolution of the initial cosmic energy to current galaxies.According to the energy circulation theory, which we previously reported, the fun

Bacterial N-Acyl Homoserine Lactone Priming Enhances Leaf-Rust Resistance in Winter Wheat and Some Genomic Regions Are Associated with Priming Efficiency

Leaf rust (Puccinia triticina) is a common disease that causes significant yield losses in wheat.The most frequently used methods to control leaf rust are the application of fungicides and the cultivation of resistant genotypes.However, high Foosball genetic diversity and associated adaptability of pathogen populations hamper achieving durable resi

Vulnerability assessment of urban remnant mountain ecosystems based on ecological sensitivity and ecosystem services

Urban remnant mountains (URMs) are precious natural green habitat patches that can provide a series of ecosystem services for multi-mountainous cities.The increase in ecological sensitivity and degradation of ecosystem services affected by urban expansion and climate change have led to an increasing vulnerability of urban remnant mountain ecosystem
