The high-ion content and kinematics of low-redshift lyman limit systems
(The American Astronomical Society, 2013)We study the high-ion content and kinematics of the circumgalactic medium around low-redshift galaxies using a sample of 23 Lyman limit systems (LLSs) at 0.08 < z < 0.93 observed with the Cosmic Origins Spectrograph on ... -
High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils
(American Society for Microbiology, 2014)The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded ... -
High-Precision Branching Ratio Measurement for the Superallowed + Emitter 74Rb
(American Physical Society, 2013)A high-precision branching-ratio measurement for the superallowed β + decay of 74Rb was performed at the TRIUMF Isotope Separator and Accelerator (ISAC) radioactive ion-beam facility. The scintillating electronpositron tagging ... -
High-precision half-life determination of 14O via direct β counting
(Springer, 2022)The half-life of the superallowed Fermi β+ emitter 14O was determined to high precision via a direct β counting experiment performed at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. The result, T1/2( 14O) ... -
High-resolution insights into the in vitro developing blood-brain barrier: Novel morphological features of endothelial nanotube function
(Frontiers Media, 2021)High-resolution electron microscopy (HREM) imaging of the in vitro blood-brain barrier (BBB), is a promising modality for investigating the dynamic morphological interplay underpinning BBB development. The successful ... -
Higher education funding crisis and access: Student protests, UWC#FMF, and social movements
(University of the Western Cape, 2022)Inadequate government funding for higher education, a higher education institutional funding crisis, and students’ individual financial crises provoked students in 2015 and 2016 to mobilise themselves to protest against ... -
Higher education research in African contexts: Reflections from fieldwork in flagship universities in South Africa, Mozambique and Ethiopia
(Taylor and Francis Group, 2022)This article is written with the recognition that, as higher education studies evolve as a multidisciplinary area of inquiry, there is a need to reflect on the theoretical and practical concerns emerging from conducting ... -
Higher education students’ perceptions of online learning during COVID-19 a comparative study
(MDPI Educ. Sci., 2021)The pandemic and subsequent ‘lockdowns’ dramatically changed the educational landscape of higher education institutions. Before-COVID-19, traditional universities had choices in pedagogical practice, which included a variety ... -

(Worlds J Mens Health, 2021)Purpose The objective of this scientometric analysis was to recognize the top 100 cited articles on ‘Male infertility and Antioxidants’ and analyze its publication characteristics. Materials and Methods The Scopus ... -
A highly responsive nh3 sensor based on pd-loaded zno nanoparticles prepared via a chemical precipitation approach
(ScienceDirect, 2019)The gas-detecting ability of nanostructured ZnO has led to significant attention being paid to the development of a unique and effective approach to its synthesis. However, its poor sensitivity, cross-sensitivity to humidity, ... -
Highly-dispersed vanadium nitride supported on porous nitrogen-doped carbon material as a high-performance cathode for lithium-sulfur batteries
(Wiley, 2022)Transition metals and their compounds supported on carbon materials are widely used as cathodes for lithium-sulfur batteries. Vanadium nitride is considered to be a promising cathode because of its good adsorption capacity ... -
