Chytrid fungi and global amphibian declines
(Springer Nature, 2020)Discovering that chytrid fungi cause chytridiomycosis in amphibians represented a paradigm shift in our understanding of how emerging infectious diseases contribute to global patterns of biodiversity loss. In this Review ... -
Chytrid pathogen (Batrachochytrium dendrobatidis) in African amphibians: a continental analysis of occurrences and modeling of its potential distribution
(Herpetologists' League, 2020)The fungal pathogen Batrachochytrium dendrobatidis (Bd) is implicated in global declines of amphibian populations and has been documented in African specimens originally collected as far back as the 1930s. Numerous recent ... -
Cibulka correlation for ternary excess/deviation properties of C2mim EtSO4 (x1) + acetic or propionic acid (x2) + acetonitrile (x3) systems at different temperatures
(Elsevier, 2017)In this perspective, the main intention is to reveal the possible intra and inter molecular interactions between ternary ionic liquid systems. The excess molar volume (VE123), isentropic compressibility (ks) and deviation ... -
Circulating DNA: its origin and fluctuation
(Wiley, 2008)Circulating DNA is present in the blood of all individuals, but it has been found that cancer patients and patients with a variety of other conditions have increased amounts of these circulating DNA fragments in their ... -
Cirolana bambang, a distinctive new species of Cirolana Leach, 1818 (Crustacea: Isopoda: Cirolanidae) from Bitung, Indonesia
(Magnolia Press, 2018)Cirolana bambang sp. nov. from Bitung, North Sulawesi, Indonesia is described. The species can be recognised by generally smooth body with small, acute, submedian nodules on pleonites 4–5 and the anterior dorsal surface ... -
Cirolana phuketensis, a new species of marine isopod (Crustacea, Isopoda, Cirolanidae) from the Andaman Sea coast of Thailand
(Pensoft, 2017)Cirolana phuketensis sp. n. was collected from coral rubble from the Andaman sea coast of Thailand. C. phuketensis sp. n. is described and fully illustrated; C. phuketensis sp. n. can be recognized by the presence of ... -
Class II 6.7 GHz methanol maser association with young massive cores revealed by ALMA
(IOP, 2017)We explored the implication of the association (or lack of it) of 6.7 GHz class II methanol (CH3OH) masers with massive dense cores (MDCs) detected (within a sample of ATLASGAL selected infrared quiet massive clumps) at ... -
A class of goodness-of-fit tests based on a new characterization of the exponential distribution
(Taylor & Francis, 2008)A new characterisation of the exponential distribution in the class of new better than used in expectation (NBUE) life distributions is presented. Utilising this characterisation, a new class of goodness-of-fit tests for ... -
A class of goodness-of-fit tests for circular distributions based on trigonometric moments
(IDESCAT, 2019)We propose a class of goodness–of–fit test procedures for arbitrary parametric families of circular distributions with unknown parameters. The tests make use of the specific form of the characteristic function of the ... -
Class ranking of secondary schools in the North West province of South Africa
(ORSSA, 2016)The education system in South Africa finds itself in a dismal position. Existing research reports and general news bulletins suggest that schools in South Africa suffer from a general lack of efficiency measures and therefore ... -
Classes of sequentially limited operators
(Cambridge Univ Press, 2016)The purpose of this paper is to present a brief discussion of both the normed space of operator p-summable sequences in a Banach space and the normed space of sequentially p-limited operators. The focus is on proving that ... -
Classical and fractional analysis of the effects of silicosis in a mining community
(Elsevier, 2020)A mathematical model for the transmission dynamics of silicosis in a mining environment is designed and its qualitative analysis is given. The model takes into account the severity of silica dust exposure in a mining ... -
Classical model of Prandtl's boundary layer theory for radial viscous flow: application of (G'/G)- expansion method
(Eudoxus Press, 2017)In this paper, the exact closed-form solutions of the Prandtl's boundary layer equation for radial ow models with uniform or vanishing mainstream velocity are derived by using the (G'/G)-expansion method. Many new exact ... -
Classification and description of the vegetation in the Spitskop area in the proposed Highveld National Park, North West Province, South Africa
(AOSIS, 2012)The objective of the proposed Highveld National Park (HNP) is to conserve a considerable area of the poorly conserved Rocky Highveld Grassland and Dry Sandy Highveld Grassveld of the western Grassland Biome in South Africa. ... -
Classification and taxonomy of vegetable macergens
(Frontiers Media, 2015)Macergens are bacteria capable of releasing pectic enzymes (pectolytic bacteria). These enzymatic actions result in the separation of plant tissues leading to total plant destruction. This can be attributed to soft rot ... -
Classification of the Eastern Scarp Forests
(Springer, 2018)This chapter brings the first comprehensive classification of the Eastern Scarp Forest. These are very fragmented and relictual forests, structurally complex, rich in tropical elements as well as species of conservation ... -
Classifying aerosol type using in situ surface spectral aerosol optical properties
(EGU, 2017)Knowledge of aerosol size and composition is important for determining radiative forcing effects of aerosols, identifying aerosol sources and improving aerosol satellite retrieval algorithms. The ability to extrapolate ... -
Classifying bent radio galaxies from a mixture of point-like/extended images with machine learning
(IEEE, 2016)The hypothesis that bent radio sources are supposed to be found in rich, massive galaxy clusters and the avalibility of huge amount of data from radio surveys have fueled our motivation to use Machine Learning (ML) to ... -
Classifying bilinear differential equations by linear superposition principle
(World Scientific Publishing, 2016)In this paper, we investigate the linear superposition principle of exponential traveling waves to construct a sub-class of N-wave solutions of Hirota bilinear equations. A necessary and sufficient condition for Hirota ... -
Clifford-Fischer theory applied to a group of the form 2_1+6:((31+2:8):2)
(Iranian Mathematical Society (IMS), 2017)In our paper [A. B. M. Basheer and J. Moori, On a group of the form 210:(U5(2):2)] we calculated the inertia factors, Fischer matrices and the ordinary character table of the split extension 210:(U5(2):2) by ...
