The aims of the present article are twofold. First, it attempts to theorise the thematic and ontological intersection between phenomenological and black bioethics and proposes 'Ontic-Black Bioethics', a neologism to evince how the corporeal misconceptions (such as race construct, bodily othering and colourism) become the cultural impediment for black women healthcare professionals. The article draws specific insights from the philosophical anthropology of race, ranging from Richard Polt to Sarah Ahmed, to understand the epistemic structures of scientific racism.

The bulk magnetization and neutron diffraction suggest a ferrimagnetic order (TC∼49 K) between between Mnand Crspins. Due to the non-equivalent Mn atoms (labelled as Mn(1) and Mn(2) which have tetrahedral and planar oxygen coordinations, respectively) and the Cr atom in the centre of distorted oxygen octahedron in the unit cell, the exchange interactions are more complex than that expected from a two sublattice magnetic system.

The design of a high-speed and energy-efficient adder is thus useful and important for practical applications. In this context, this paper presents the designs of novel asynchronous carry look-ahead adders (CLAs) viz.

For each of the three possible Cr/Ti cationic arrangements in the unit cell, considered in this work, the non-magnetic band structure shows distinct traits with significant flat-band regions leading to largedensity of states around the Fermi energy. The Crion in SrCrTiO, which is asystem, shows a reverse splitting of theorbitals.

The 2p x-ray absorption spectra show that Mn and Ni are in 4+ and 2+ states respectively. Based on charge transfer multiplet analysis of the 2p XPS spectra of both ions, we find charge transfer energies [Formula: see text] of 3.
