Iodine status assessment in South African adults according to spot urinary iodine concentrations, prediction equations, and measured 24-h iodine excretion
(MDPI, 2018)The iodine status of populations is conventionally assessed using spot urinary samples to obtain a median urinary iodine concentration (UIC) value, which is assessed against standard reference cut-offs. The assumption that ... -

Ion selectivity and membrane potential effects of two scorpion pore-forming peptides
(North-West University, 2005)Parabutoporin (PP) and opistoporin 1 (OP1) are cation, a-helical antimicrobial peptides isolated from the southern African scorpion species, Parabuthus schlechteri and Opistophthalmus carinatus, respectively. Along with ... -
Ionic conductivity of alkali halides across a polyaniline-zirconium (iv)-arsenate membrane
(CEE, 2013)In continuation to our previous work with composite polyaniline-zirconium (IV)-arsenate (PZA), we further extended with the conductivity measurements in this report. All the calculations reported in here were extracted ... -
Ionic liquids as green and sustainable corrosion inhibitors for metals and alloys: an overview
(Elsevier, 2017)Development of green and sustainable technologies for the corrosion prevention is highly desirable due to increasing ecological awareness and strict environmental regulations. In the last decade, metallic corrosion inhibition ... -
Ionic liquids as Green Solvents for Cellulose Chemistry
(North-West University (South Africa), 2019)Cellulose is a polymer that lacks solubility in many conventional solvents and this limits its applications. Recently ionic liquids (ILs) have been reported to be good and green solvents for the cellulose processing. ... -
Ionic salt (4-ethoxybenzyl)-triphenylphosphonium bromide as a green corrosion inhibitor on mild steel in acidic medium: experimental and theoretical evaluation
(Royal Society of Chemistry, 2017)A new phosphonium salt (4-ethoxybenzyl)-triphenylphosphonium bromide (EBTPPB), having different substituents attached to phosphorous and having different anions, is investigated as an inhibitor for mild steel (MS) corrosion ... -
Ionization rates in the heliosheath and in astrosheaths: spatial dependence and dynamical relevance
(EDP Sciences, 2014)Context. In the heliosphere, especially in the inner heliosheath, mass-, momentum-, and energy-loading induced by the ionization of neutral interstellar species plays an important, but for some species, especially helium, ... -
Ionizing radiation as imaging tool for coal characterization and gasification research
(North-West University, 2012)In this study, imaging with ionizing radiation was evaluated as a research technique in coal research. Part of the evaluation was to conduct a thorough literature survey as well as a preliminary investigation into coal ... -
Ionospheric electron number densities from CUTLASS dual-frequency velocity measurements using artificial backscatter over EISCAT
(American Geophysical Union, 2016)Using quasi-simultaneous line-of-sight velocity measurements at multiple frequencies from the Hankasalmi Cooperative UK Twin Auroral Sounding System (CUTLASS) on the Super Dual Auroral Radar Network (SuperDARN), we calculate ... -

(1997)According to present provincial division Schweizer-Reneke, of which Ipelegeng forms part, is in the North-West Province. Neighbouring towns are Delareyville, Bloemhof en Christiana. SchweizerReneke is 322 kilometres from ... -
Ipsilateral corticomotor responses are confined to the homologous muscle following cross-education of muscular strength
(Canadian Science Publishing, 2018)Cross-education of strength occurs when strength-training 1 limb increases the strength of the untrained limb and is restricted to the untrained homologous muscle. Cortical circuits located ipsilateral to the trained limb ... -
Iranian Cunaxidae (Acari: Prostigmata: Bdelloidea). Part 3. Subfamily Cunaxoidinae
