Amelioration of iron mine soils with biosolids: effects on plant tissue metal content and earthworms
(Springer, 2016)The achievement of environmentally sound and economically feasible disposal strategies for biosolids is a major issue in the wastewater treatment industry around the world, including Swaziland. Currently, an iron ore mine ... -
An amended description of two Gyrodactylus species (Platyhelminthes: Monogenea) parasitizing Antarctic Notothenioid fish
(Cambridge Univ Press, 2020)Species identification based on the morphometry of opisthaptoral hard parts, in combination with internal transcribed spacer ribosomal DNA (ITS rDNA) region sequences, confirmed the presence of four viviparous Gyrodactylus ... -
"America's Mandela": South African responses to the rise of Barack Obama
(Institute for Contemporary History: Sabinet, 2013)In this article reactions in the South African media to the emergence of Barack Obama as contender in the 2008 US presidential election, then as official Democratic Party presidential candidate and then as US President-elect ... -
American Christians for and against Parsifal: Debating the Holy Grail Opera in New York
(AOSIS, 2017)The appropriateness of Christian themes in the performing arts has often been debated. Defenders have argued that various media, including drama, can serve as instruments of spiritual edification, while critics have contended ... -
Amino acid based imidazolium zwitterions as novel and green corrosion inhibitors for mild steel: experimental, DFT and MD studies
(Elsevier, 2017)Three novel amino acids based corrosion inhibitors namely 2-(3-(carboxymethyl)-1H-imidazol-3-ium-1-yl)acetate (AIZ-1), 2-(3-(1-carboxyethyl)-1H-imidazol-3-ium-1-yl)propanoate (AIZ-2) and 2-(3-(1-carboxy-2-phenylethyl)-1H ... -
Ammonia gas sensing characteristics of V2O5 nanostructures: a combined experimental and ab initio density functional theory approach
(Elsevier, 2020)A combined experimental and density functional theory of α-V2O5 for ammonia gas sensing have been investigated. The material was synthesized from hydrated NH4VO3 in CVD at 400 °C in N2 atmosphere for different time (12 h ... -
Ammonia-oxidizing microorganisms: key players in the promotion of plant growth
(Instituto de Agroindustria, 2017)Nitrogen (N) is the most important mineral nutrient required by plants. Although some plants can directly utilize N, ammonium (NH4+) and nitrate (NO3-) are the only forms of N that are usable to most plants. Ammonia-oxidizing ... -
Ammonium sulphate and/or ammonium bisulphate as extracting agents for the recovery of aluminium from ultrafine coal fly ash
(Elsevier, 2017)We recently showed that the selective extraction of aluminium from the amorphous phase of a South African ultrafine coal fly ash can be achieved via thermochemical treatment with ammonium sulphate for 1 h followed by aqueous ... -
Amorphous azithromycin with improved aqueous solubility and intestinal membrane permeability
(Taylor & Francis, 2015)Azithromycin (AZM) is a poorly soluble macrolide antibacterial agent. Its low solubility is considered as the major contributing factor to its relatively low oral bioavailability. The aim of this study was to improve the ... -
Amorphous sulfadoxine: a physical stability and crystallization kinetics study
(Springer Nature, 2016)Poor aqueous solubility of drugs and the improvement thereof has always been a challenge for the pharmaceutical industry.With this, one of the focuses of the pharmaceutical research scientist involves investigating ... -
The ampakine, Org 26576, bolsters early spatial reference learning and retrieval in the Morris water maze: a subchronic, dose-ranging study in rats
(Wolters Kluwer, 2009)Ampakines have shown beneficial effects on cognition in selected animal models of learning. However, their ability to modify long-term spatial memory tasks has not been studied yet. This would lend credence to their possible ... -
Amphibian chytrid fungus in Africa – realigning hypotheses and the research paradigm
(Wiley, 2020)The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), responsible for numerous amphibian declines and extinctions, was previously thought to originate from the African continent. This was based on infected ... -
Amphibian fungal panzootic causes catastrophic and ongoing loss of biodiversity
(AAAS, 2019)Rapid spread of disease is a hazard in our interconnected world. The chytrid fungus Batrachochytrium dendrobatidis was identified in amphibian populations about 20 years ago and has caused death and species extinction at ... -
Amphibian skin defences show variation in ability to inhibit growth of Batrachochytrium dendrobatidis isolates from the Global Panzootic Lineage
(Microbiology Society, 2017)The fungal pathogen Batrachochytrium dendrobatidis has caused declines and extinctions in hundreds of amphibian species across the world. Virulence varies among and within lineages; the Global Panzootic Lineage (GPL) is ... -
Amphibian survey and current absence of Batrachochytrium dendrobatidis (Bd) in Ivoloina Park, Toamasina (eastern Madagascar)
(Taylor & Francis, 2014)Amphibians are threatened globally by the chytridiomycete fungus Batrachochytrium dendrobatidis (Bd), which is still expanding in range. Madagascar, rich in amphibian diversity, remains one of the few places that the fungus ... -
Amphibian symbiotic bacteria do not show a universal ability to inhibit growth of the global panzootic lineage of Batrachochytrium dendrobatidis
(Amer Soc Microbiology, 2015)Microbiomes associated with multicellular organisms influence the disease susceptibility of hosts. The potential exists for such bacteria to protect wildlife from infectious diseases, particularly in the case of the globally ... -
Amphibiophilus mooiensis n. sp. (Nematoda: Amphibiophilidae), a parasite of Amietia delalandii (Duméril & Bibron) (Amphibia: Pyxicephalidae) from South Africa
(Springer, 2018)Four species of the genus Amphibiophilus Skrjabin, 1916 from pyxycephalid frogs in southern and central Africa are currently recognised as valid. Several specimens of Amphibiophilus were found in material from the common ... -
An amplified description for the elusive Cordylogyne argillicola (Apocynaceae-Asclepiadoideae) from Namibia
(Magnolia Press, 2017)Owing to the brief description, and in the absence of any known type collection of Cordylogyne argillicola, the application of the name remained unresolved for over a century. Type material that was recently discovered in ... -
