Microbial community structure and relationship with physicochemical properties of soil stockpiles in selected South African opencast coal mines
(Taylor & Francis, 2019)At present, there is no comprehensive soil quality assessment practice for soil stockpiles in the South African coal mining industry. Soil microorganisms and enzymes are suitable indicators for soil quality monitoring. ... -
Microbial metabolomics: essential definitions and the importance of cultivation conditions for utilizing Bacillus species as bionematicides
(Wiley, 2019)Root‐knot nematodes are destructive phytopathogens that damage agricultural crops globally, and there is growing interest in the use of biocontrol based on rhizobacteria such as Bacillus to combat Meloidogyne species. It ... -
Microbial phosphorus solubilization and Its potential for use in sustainable agriculture
(Frontiers Media, 2017)The use of excess conventional Phosphorus (P) fertilizers to improve agricultural productivity, in order to meet constantly increasing global food demand, potentially causes surface and ground water pollution, waterway ... -
Microbial signature lipid biomarker analysis: an approach that is still preferred, even amid various method modifications
(Wiley, 2015)The lipid composition of microbial communities can indicate their response to changes in the surrounding environment induced by anthropogenic practices, chemical contamination or climatic conditions. A considerable number ... -
Microbiological safety of ready‐to‐eat foods in low‐ and middle‐income countries: a comprehensive 10‐year (2009 to 2018) review
(Wiley, 2020)Ready‐to‐eat foods (RTEs) are foods consumed without any further processing. They are widely consumed as choice meals especially by school‐aged children and the fast‐paced working class in most low‐ and middle‐income ... -
Microbiomics of Namib Desert habitats
(Springer, 2020)The Namib Desert is one of the world’s only truly coastal desert ecosystem. Until the end of the 1st decade of the twenty-first century, very little was known of the microbiology of this southwestern African desert, with ... -
Micronutrients (B, Co, Cu, Fe, Mn, Mo, and Zn) content in made tea (Camellia sinensis L.) and tea infusion with health prospect: a critical review
(Taylor & Francis, 2017)Tea (Camellia sinensis L.) is a perennial acidophilic crop, and known to be a nonalcoholic stimulating beverage that is most widely consumed after water. The aim of this review paper is to provide a detailed documentation ... -
Micropredation by gnathiid isopods on settlement-stage reef fish in the eastern Caribbean Sea
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2015)The transition from a planktonic larval stage to a benthic or demersal juvenile stage is a crucial event in the life history of coral reef fishes, and recruitment success has a strong influence on reef-fish population ... -
Millimeter-wave monitoring of active galactic nuclei with the Africa millimetre telescope
(MDPI, 2019)Active galactic nuclei are the dominant sources of gamma rays outside our galaxy and are also candidates for the source of ultra-high energy cosmic rays. In addition to being emitters of broad-band non-thermal radiation ... -
The millisecond pulsar contribution to the rising positron fraction
(Sissa Medialab, 2016)Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed by PAMELA and AMS−02. The Fermi Large ... -
Mineral concentration and standing crop yield dynamics of forages in semi-arid communal grazing lands of South Africa: effect of landscape and season
(Animal Nutrition Association, 2016)Semi-arid African rangelands are characterized by heterogeneous topography and distribution of grazing forages. In these ecosystems, grasses are the main sources of livestock feed with few species contributing to the bulk ... -
Mineralogical, chemical, and petrographic properties of selected South African power stations’ feed coals and their corresponding density separated fractions using float-sink and reflux classification methods
(Taylor & Francis, 2019)Three South African feed coal samples for the combustion process were beneficiated to produce carbon-rich and mineral-rich fractions. The mineralogical, petrographical, and chemical properties of these feed coals and ... -
Mineralogy and bioavailability of Selected Heavy Metals in Agricultural Soils
(ResearchGate, 2014)Contamination of soils with heavy metals from agrochemicals presents a threat to food security and safety in communities depending on these soils for subsistence. Knowledge of the various factors and properties dictating ... -
Mineralogy and petrology of chars produced by South African caking coals and density-separated fractions during pyrolysis and their effects on caking propensity
(ACS, 2019)Thermochemical processes use low-rank bituminous coal to produce steam and synthetic gas. Caking coal particles can soften, swell, and coalesce in the South African boilers and fixed-bed gasifiers during pyrolysis and have ... -
Mineralogy of furnace deposits produced by South African coals during pulverized-fuel combustion tests
(ACS, 2015)Pilot-scale combustion tests were carried out on coals with low (13.5%) and high (39.6%) ash percentages from the Highveld Coalfield of South Africa, using the ALS-ACIRL 100–200 kW Combustion Test Facility. The mineral ... -
Minerals, trace elements and antioxidant phytochemicals in wild African dark-green leafy vegetables (morogo)
(ASSAf, 2009)Wild African dark-green leafy vegetables (morogo) are an important constituent of the traditional starch-based African diet. Three wild morogo types were sampled from different geographical regions in South Africa to ... -
The mini-neutron monitor: a new approach in neutron monitor design
(EDP, 2020)The near-Earth cosmic ray flux has been monitored for more than 70 years by a network of ground-based neutron monitors (NMs). With the ever-increasing importance of quantifying the radiation risk and effects of cosmic rays ... -
