Global stability and Hopf bifurcation of a delayed computer virus propagation model with saturation incidence rate and temporary immunity
(World Scientific Publishing, 2016)
In this paper, a delayed computer virus propagation model with a saturation incidence rate and a time delay describing temporary immune period is proposed and its dynamical behaviors are studied. The threshold value ?0 is ...
Geospatial analyses in support of heavy metal contamination assessments of soil and grass along highways at Mafikeng, South Africa
(CONSAS, 2016)
Heavy metals in the environment are of concern due to detrimental effects, which include disturbance of plant physiology. This paper presents an exploratory assessment of heavy metal contamination along the main highways ...
Group classification and conservation laws of the generalized Klein-Gordon-Fock equation
(World Scientific Publishing, 2016)
In the present paper, we perform Lie and Noether symmetries of the generalized Klein-Gordon-Fock equation. It is shown that the principal Lie algebra, which is one-dimensional, has several possible extensions. It is further ...
Effect of extension service(s) and socio-economic characteristics on the livelihood of Nguni cattle development project beneficiaries in North West Province: a tobit-ols regression approach
(South African Society of Agricultural Extension (SASAE), 2017)
The place of extension and advisory service(s) in enhancing farmer's knowledge, skills, as well as technologies cannot be overemphasised. This study was carried out in the North West Province of South Africa, with the aim ...
Electrochemical detection of epinephrine using polyaniline nanocomposite films doped with TiO2 and RuO2 nanoparticles on multi-walled carbon nanotube
(Elsevier, 2017)
Electrochemical properties of functionalized MWCNT/polyaniline doped with metal oxide (TiO2, RuO2) nanoparticles were explored. Successful synthesis of MWCNT, TiO2, RuO2, PANI, MWCNT-PANI-TiO2, and MWCNT-PANI-RuO2 nano ...
Use of sediment source fingerprinting to assess the role of subsurface erosion in the supply of fine sediment in a degraded catchment in the Eastern Cape, South Africa
(Elsevier, 2017)
Sediment source fingerprinting has been successfully deployed to provide information on the surface and subsurface sources of sediment in many catchments around the world. However, there is still scope to re-examine some ...
Nature of the molecular interaction between 1-ethyl-3-methylimidazolium methylsulfate ionic liquid with higher chain alcohol through binary mixtures containing thermophysical properties
(Elsevier, 2017)
In this work, the sophisticated thermodynamic techniques: thermodynamic and thermophysical properties of binary mixtures of 1-ethyl-3-methylimidazolium [C2mim][MeSO4] with various organic solvents were determined at different ...
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 ...
Variational approach and exact solutions for a generalized coupled Zakharov-Kuznetsov system
(Elsevier, 2017)
In the present paper, we obtain a variational principle for a generalized coupled Zakharov-Kuznetsov system, which does not admit any Lagrangian formulation in its present form. The eminent Noether's theorem will then be ...
Trigonal curves and algebro-geometric solutions to soliton hierarchies II
(Royal Society, 2017)
This is a continuation of a study on Riemann theta function representations of algebro-geometric solutions to soliton hierarchies. In this part, we straighten out all flows in soliton hierarchies under the Abel-Jacobi ...
