(University of the Western Cape, 2021)Historically, Morocco experienced widespread political repression during the 1970s through to the early 1990s. Through its exploitations, the monarchy regime repressed any claims aimed at challenging its authoritarian form ... -
Effect of the annealing atmosphere on the layer interdiffusion in Pd/Ti/Pd multilayer stacks deposited on pure Ti and Ti-alloy substrates
(University of the Western Cape, 2019)Pd(50 nm)/Ti(25 nm)/Pd(50 nm) multilayer stack has been deposited on Ti and Ti6Al4V substrates; we have studied the intermixing of layers upon annealing at the hydrogenation temperature of 550 °C, under vacuum, H/Ar gas ... -
Effect of the COVID-19 pandemic response on intrapartum care, stillbirth, and neonatal mortality outcomes in Nepal: a prospective observational study
(Elsevier, 2020)Background: The COVID-19 pandemic response is affecting maternal and neonatal health services all over the world. We aimed to assess the number of institutional births, their outcomes (institutional stillbirth and neonatal ... -
Effect of the environment on star formation activity and stellar mass for star-forming galaxies in the COSMOS field
(2020-11)We investigate the relationship between the environment and the galaxy main sequence (the relationship between stellar mass and star formation rate), as well as the relationship between the environment and radio luminosity ... -
Effect of the metabolic syndrome on male reproductive function: a case-controlled pilot study
(Wiley, 2014)The metabolic syndrome (MetS) is a constellation of various risk factors. This study aimed to investigate the effect of MetS on testosterone and progesterone, and semen parameters, in a case-controlled pilot study. Male ... -
Effect of the structure of Ni nanoparticles on the electrocatalytic activity of Ni@Pd/C for formic acid oxidation
(Elsevier, 2013)Ni@Pd/C catalysts were synthesized, using Ni/C with different crystalline structures prepared with various ligands. A series of characterizations were performed by transmission electron microscopy, X-ray diffraction, X-ray ... -
Effect of various tooth-whitening products on enamel microhardness
(South African Dental Association, 2009)Objectives: The purpose was to evaluate the effect of various tooth-whitening products on the South African market, containing carbamide peroxide (CP) or hydrogen peroxide (HP), on enamel microhardness. Methods: Enamel ... -
The effect of varying dietary nutrient densities on the relative growth of ostrich body components
(OpenJournals Publishing AOSIS (Pty) Ltd, 2020)The influence of varying dietary protein and energy levels on the relative growth of body components of ostriches was evaluated over a 244-day growth period. One hundred twenty 1-day-old ostrich chicks were randomly ... -
The effect of weak lensing on distance estimates from supernovae
(American Astronomical Society, 2013)Using a sample of 608 Type Ia supernovae from the SDSS-II and BOSS surveys, combined with a sample of foreground galaxies from SDSS-II, we estimate the weak lensing convergence for each supernova line of sight. We find ... -
