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 ... -
High-sensitivity c-reactive protein among people living with hiv on highly active antiretroviral therapy: a systemic review and meta-analysis
(BioMed Central Ltd, 2024)The pathological consequences of inflammation persist in people living with the human immunodeficiency virus (PLWH), regardless of the positive outcomes of highly active antiretroviral therapy (HAART). The current systematic ... -
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 ... -
