Há 8 horas · The report says changes to just three metrics would bring the gap down to 14%. “If First Nations adults were to have the same average levels as non-Indigenous adults on just 3 of these critical factors — that is, the same average equivalised household income, same average employment rate and hours worked, and same average smoking rate ...
Há 8 horas · A metal (from Ancient Greek μέταλλον (métallon) 'mine, quarry, metal') is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not. [1] : .
Há 1 dia · The Imperial Roman Army was the military land force of the Roman Empire from 27 BC to 476 AD, [1] and the final incarnation in the long history of the Roman army. This period is sometimes split into the Principate (27 BC – 284 AD) and the Dominate (284–476) periods. Under Augustus ( r. 27 BC – AD 14 ), the army consisted of legions ...
Há 8 horas · In the era of sleek, super slender suspension bridges, facing the issue of stability against dynamic wind actions represents an increasingly complex challenge. Despite the significant progress over the last decades, the impact of atmospheric turbulence on bridge stability remains partially not understood, evoking the need for innovative research approaches. This study aims to address a gap in ...
Há 8 horas · After examination of the obtained Tauc plots (Ahʋ) 2 vs. hʋ , the difference in the optical band gap is clear. If we exclude the 2% sample, it is noticeable that by increasing the copper doping percentage (the concentration of dopant) the optical band gap increases from 3.01 eV for undoped TiO 2 to 3.1 eV for 8% copper-doped TiO 2.
