Characterization of solid lipid dispersions prepared by hot fusion containing a double-fixed dose combination of artemether and lumefantrine
(Taylor & Francis, 2020)bjective The World Health Organization has called for the development of novel drug delivery systems to combat malaria – the fourth most prevalent cause of death globally. The plausibility of utilizing hot fusion to prepare ... -
Characterization of species differences in xenobiotic metabolism in non-experimental animals
(Pharmaceutical Society of Japan, 2017)The ability to metabolize xenobiotics in organisms has a wide degree of variation among organisms. This is caused by differences in the pattern of xenobiotic bioaccumulation among organisms, which affects their tolerance. ... -
Characterization of tabanid flies (Diptera: Tabanidae) in South Africa and Zambia and detection of protozoan parasites they are harbouring
(Cambridge Open, 2017)Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at ... -
Characterization of the cell-free DNA released by cultured cancer cells
(Elsevier, 2016)The most prominent factor that delays the translation of cell-free DNA (cfDNA) analyses to clinical practice is the lack of knowledge regarding its origin and composition. The elucidation of the former is complicated by ... -
Characterizations of multinormality and corresponding tests of fit, including for GARCH models
(Cambridge Univ Press, 2019)We provide novel characterizations of multivariate normality that incorporate both the characteristic function and the moment generating function, and we employ these results to construct a class of affine invariant, ... -
Characterizing light-absorbing aerosols in a low-income settlement in South Africa
(Taiwan Association for Aerosol Research, 2020)Light‑absorbing aerosols, particularly black carbon (BC), have significant impacts on human health and the climate. They are also the least‑studied fraction of atmospheric particles, particularly in residential areas of ... -
Characterizing the γ-ray long-term variability of PKS 2155-304 with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2017)Studying the temporal variability of BL Lac objects at the highest energies provides unique insights into the extreme physical processes occurring in relativistic jets and in the vicinity of super-massive black holes. To ... -
Charge transport, interfacial interactions and synergistic mechanisms in BiNbO4/MWO4 (M = Zn and Cd) heterostructures for hydrogen production: insights from a DFT+U study
(RSC, 2017)In the 21st century, the growing demand of global energy is one of the key challenges. The photocatalytic generation of hydrogen has attracted extensive attention to discuss the increasing global demand for sustainable and ... -
The charge-sign dependent effect in the solar modulation of cosmic rays
(Elsevier, 2014)The centennial anniversary of the discovery of cosmic rays was in 2012. Since this discovery considerable progress has been made on several aspects related to galactic cosmic rays in the heliosphere. It is known that they ... -
Charge-sign dependent modulation of cosmic ray electrons and positrons up to extreme solar maximum conditions
(PoS, 2017)The charge-sign dependent modulation of cosmic rays is an important topic in solar modulation studies, providing insights into gradient, curvature, and current sheet drifts. Such studies, at higher levels of solar activity, ... -
Charismatic appropriations of Edward W. Fasholé-Luke's Theologia Africana
(Equinox Publishing, 2016)Although scholarly literature about the theologies of newer Pentecostal and Charismatic movements (CMs) in Africa is growing, few attempts have been made to apply specific models proposed by the giants of African theology ... -
Charismatic movements, state relations and public governance in Sierra Leone
(Edinburgh University Press, 2017)Sierra Leone has seen the rise of Charismatic movements that are bringing about greater levels of co-operation with the state. This new church development aims at renewing the Christian faith and projecting a more proactive ... -
The charismatic praying mantid: a gateway for insect conservation
(Taylor & Francis, 2020)Praying mantids (Mantodea) are not only apex predators with a ‘mystical’ status, but are also regarded as a kind of oracle and, in some cultures, as omens associated with good or bad. In the future, the cultural, mystical ... -
Cheap 0.36 dB broadband multipath LNA
(Institution of Engineering and Technology (IET), 2012)A two-path low-noise amplifier (LNA) designed for the planned MeerKAT radio telescope is presented. The LNA has a noise figure (NF) of less than 0.36 dB and input return loss of less than 12 dB from 0.7 to 1.8 GHz. It ... -
Chebyshev collocation method for the solution of a system of second-order boundary value problems
(SAS International Publications, 2016)In this paper, we present a new numerical approach based on Chebyshev polynomials of the first kind for solving a system of second-order boundary value problems associated with obstacle, unilateral and contact problems. ... -
A checklist for testing measurement invariance
(Taylor & Francis, 2012)The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor ... -

(Taylor & Francis, 2012)The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor model ... -
Checklist of acanthocephalan parasites of South Africa
(Pensoft, 2018)Twenty-one species of acanthocephalans, representative of thirteen genera from ten families of seven orders and three classes, are included in this updated checklist of acanthocephalans in South Africa. Although South ... -
Chemical additives enhance the activity of a Bt‐based biopesticide targeting the beet webworm larvae
(Wiley, 2020)Spoladea recurvalis (Fbr.) (Lepidoptera: Crambidae) larvae can cause up to 100% foliage loss on amaranths during severe outbreaks. The Bacillus thuringiensis Subsp. kurstaki product Halt® is a biologically safe biopesticide ... -
Chemical and physical characterization of spent coffee ground biochar treated by a wet oxidation method for the production of a coke substitute
(Elsevier, 2020)Coke production relies on the availability, cost and quality of coking coal. Depleting coking coal resources and environmental pressure force the metallurgical industry to search for alternative methods to produce coke. ...
