Massive elliptical galaxies are typically observed to have central cores in their projected radial light profiles. Such long been thought form through `binary scouring' as supermassive black holes (SMBHs), brought mergers, a hard binary and eject stars from the galactic centre. However, most massive cores, like ~3kpc core A2261-BCG, remain challenging explain this way. In paper, we run suite of...

Abstract Egyptian Chorisia hollow fibers have been blended with cotton waste, polyester and raw bamboo at various ratios weft counts using open-end spinning. The fabrics of hybrid composites were subjected to atmospheric plasma, pectinase, lipase enzyme treatments, as well the substitution all hazardous chemicals, sustainable alternatives traditional alkaline scouring. impacts treatments on hol...

In recent years, the water–sand composition of Yangtze River channel has changed due to influence human factors, especially construction water reservoirs such as Three Gorges Project. Changing conditions have a long-term impact on shaping river morphology in middle and lower reaches River, erosion retreat local sections caused great harm embankment projects. This paper focuses evolution mechani...

An electron microprobe (EMP) analysis of silica (SiO,) deposition in the epidermis of developing internodes of the perennial scouring rush (Equisetum hyemale var. affine) indicates that SiO, is first detected in the stomata1 apparatus beginning with internode 3, then the epidermal papillae (internode 8), and finally in radial cell walls of the long epidermal cells (internode 10). This process i...
