Objective: The oral health of HIV positive patients may be compromised because of their depressed immunity and may increase their risk of developing some oral lesions.This study was carried out to assess the relationship of the oral hygiene status and practices with oral lesions in HIV positive patients at a dedicated HIV clinic in Nigeria.Method:
This paper proposes a control scheme to force homogeneity for heterogenous network of the grid-forming (GFM) inverters in power electronics dominated grid (PEDG) to enable their aggregation and coherent dynamic interaction.Increased penetration of the renewable energy in distributed generation (DG) fashion is moving traditional power system to a hi
The photochromic properties of oxygen-containing yttrium hydride Cutting Board thin films are directly dependent on the oxygen concentration in the material.We use 16O/18O labelling to study oxidation of YH2 films.Oxygen penetrates the film through grain boundaries and intercolumnar voids oxidising the whole film thickness, without pronounced surfa
The silicification Accessories mechanism in sponges is a biologically controlled process where the complex and amazing shape of spicules is the result of the hierarchical assembly of silicon particles to form a composite structure with organic compounds, mainly constituted by proteins.In this work, using an integrated approach of transcriptomic and
Underwater radiated noise is part of the anthropogenic emissions into the environment and as such a pressing problem for the preservation of the marine ecosystem.In order to direct Collections attention to the most relevant noise sources associated with ships it is crucial to precisely determine the local origins of the acoustic emissions.As acoust
