Core bacterial community of soy-daddawa: insights from high-throughput DNA metabarcoding
(Elsevier, 2018)High-throughput sequence analysis of microbial communities in food matrices provides unprecedented insights into species richness and potential safety of foods. Here, the bacterial community of soy-daddawa, a fermented ... -
Corn biomass, uptake and fractionation of soil phosphorus in five soils amended with organic wastes as P fertilizers
(Taylor & Francis, 2020)Sustainable food production includes mitigating environmental pollution and avoiding unnecessary use of non-renewable mineral phosphate resources. Efficient phosphorus (P) utilization from organic wastes is crucial for ... -
Corn yield, phosphorus uptake and soil quality as affected by the application of anaerobically digested dairy manure and composted chicken manure
(Taylor & Francis, 2020)The excessive accumulation of animal manure in livestock production units has made manure a valuable phosphorus (P) source that if used efficiently can be a sustainable alternative to mineral P fertilizer. A two-year field ... -
Correction for a measurement artifact of the Multi-Angle Absorption Photometer (MAAP) at high black carbon mass concentration levels
(EGU, 2013)The Multi-Angle Absorption Photometer (MAAP) is a widely-used instrument for aerosol black carbon (BC) measurements. In this paper, we show correction methods for an artifact found to affect the instrument accuracy in ... -
Correction to the type locality of Tomopterna ahli (Deckert, 1938) (Anura: Pyxicephalidae), with the designation of a neotype
(Magnolia Press, 2019)Deckert described a Tomopterna as Arthroleptella ahli from South Africa in 1938. We demonstrate that the type of Tomopterna ahli (Deckert, 1938) was actually collected in Namibia, and that this nomen is a senior synonym ... -
Correction to: The use of OJIP fluorescence transients to monitor the effect of elevated ozone on biomass of canola plants
(Springer, 2019)In the original publication’s Fig. 1b, the labels J and I, should be placed at approximately 2 ms and 30 ms respectively. Also, Fig. 3C y-axis title should be written as ψEo /(1- ψEo). The corrected Figs. 1 and 3 are provided here -
Correlating early evolution of parasitic platyhelminths to Gondwana breakup
(Oxford University Press / Society of Systematic Biologists, 2011)Investigating patterns and processes of parasite diversification over ancient geological periods should involve comparisons of host and parasite phylogenies in a biogeographic context. It has been shown previously that the ... -
Correlation between rapid learnability and user preference in IVR systems for developing regions
(iIST-Africa, 2013)Access to information and communication is one of the most important needs in any population group. It is generally challenging for people in the developing world to access information because the tools and the technologies ... -
Correlation of long-term cosmic-ray modulation with solar activity parameters
(IOP Publishing, 2019)In this work, we analyze the long-term cosmic-ray modulation observed by the Hermanus neutron monitor, which is the detector with the longest cosmic-ray record, from 1957 July. For our study we use the force-field approximation ... -
Corrosion Inhibition of Aluminium Alloy in Alkaline Media by Neolamarkia Cadamba Bark Extract as a Green Inhibitor
(ESG, 2015)The aqueous extract of Neolamarkia Cadamba (NC) bark was investigated as corrosion inhibitor for aluminium alloy (AA) in 1 M NaOH solution. The techniques employed for corrosion inhibition are weight loss, polarization ... -
Corrosion Inhibition of Al–alloy in 3.5% NaCl Solution by a Natural Inhibitor: An Electrochemical and Surface Study
(ESG, 2014)Root extract of Copt is chinensis (CCR) was used and its inhibition efficiency on corrosion of Al alloy in 3.5 wt.% NaCl was investigated through surface morphology and electrochemical techniques. The Nyquist ... -
Corrosion inhibition of mild steel in 1M HCl by D-glucose derivatives of dihydropyrido [2,3-d:6,5-d'] dipyrimidine-2, 4, 6, 8(1H,3H, 5H,7H)-tetraone
(Nature Publishing Group, 2017)D-glucose derivatives of dihydropyrido-[2,3-d:6,5-d′]-dipyrimidine-2, 4, 6, 8(1H,3H, 5H,7H)-tetraone (GPHs) have been synthesized and investigated as corrosion inhibitors for mild steel in 1M HCl solution using gravimetric, ... -
Corrosion Inhibition of Steel in HCl by 2–Aminoethyl diphenylborinate
(International Journal Of Electrochemical Science, 2014)The corrosion behavior of C38 steel in HCl solution with different concentration of 2-Aminoethyl diphenylborinate C14H16BNO(DDB) was investigated by weight loss and electrochemical measurements. ... -
Corrosion inhibitors for ferrous and non-ferrous metals and alloys in ionic sodium chloride solutions: a review
(Elsevier, 2017)Metallic materials have been extensively used in marine environments particularly in production, processing and transport industries for the construction of pipelines, households, fuel tanks, oil lines, power lines, heat ... -
Corrosion mechanism of steels in MDEA solution and material selection of the Desulfurizing equipment
(ESG, 2017)In the present study, the corrosion properties of three steel were evaluated in 45 wt.% Methyldiethanolamine (MDEA) solution, saturated to the hydrogen sulfide (H2S) and carbon dioxide (CO2) as in the oilfields. Corrosion ... -
Corticospinal excitability during shortening and lengthening actions with incremental torque output
(Wiley, 2018)The modulation of motor evoked potentials (MEPs), an index of corticospinal excitability, has been shown to increase during isometric contractions with incremental torque output in accordance with the contribution between ... -
Corticospinal responses following strength training: a systematic review and meta‐analysis
(Wiley, 2017)Strength training results in changes in skeletal muscle; however, changes in the central nervous system also occur. Over the last 15 years, non‐invasive brain stimulation techniques, such as transcranial magnetic stimulation, ... -
