(MDPI, 2021-09-03)This study fabricated and characterized a self-sustaining hydrogenous content claypolyethylene composite opted for ionizing radiation shielding. Composites designated A–G were fabricated each containing 0–30 wt% of ...
-
(University of Pretoria, 2020)The aim of the study is to synthesize and characterize high quality undoped, Ce doped, Sm doped, Ce and Sm co-doped, and Ce and Al co-doped ZnO thin films and nanorods for use in optoelectronic devices, using the low-cost ...
-
(Wiley, 2023-08)This work reports on the engineering and fabrication of transparent, conductive, and flexible films made as a composite of bacterial cellulose microfibers (BMF), a polymer (either PVA or PEO), and silver nanowires (AgNWs) ...

(BioMed Central, 2018-12-21)The relationship between facial cues and perceptions of health and attractiveness in others plays an influential role in our social interactions and mating behaviors. Several facial cues have historically been investigated ...
-
(Nature Publishing Group, 2017-08-07)Facial appearance is thought to indicate immunity in humans, but very few studies have tested this relationship directly. The aim of this study was to test the relationship between direct measures of immunity, perceived ...
-
(The Royal Society, 2013-08)Recent studies suggest that facial attractiveness indicates immune responsiveness in men and that this relationship is moderated by stress hormones which interact with testosterone levels. However, studies testing whether ...
-
(Frontiers Research Foundation, 2017-10-30)Facial cues contribute to attractiveness, including shape cues such as symmetry, averageness, and sexual dimorphism. These cues may represent cues to objective aspects of physiological health, thereby conferring an ...
