Evolutionary processes involved in the diversification of chelonian and mammal polystomatid parasites (Platyhelminthes, Monogenea, Polystomatidae) revealed by palaeoecology of their hosts
(Elsevier, 2015)Polystomatid flatworms (Platyhelminthes) are monogenean parasites that infect exclusively aquatic or semi-aquatic sarcopterygians such as the Australian lungfish, amphibians, freshwater turtles and the African common ... -
An exact algorithm for the N-sheet two dimensional single stock-size cutting stock problem
(ORSSA (Operations Research Society of South Africa), 2015)The method introduced in this paper extends the trim-loss problem or also known as 2D rect- angular SLOPP to the multiple sheet situation where N same size two-dimensional sheets have to be cut optimally producing demand ... -
Exact Solitary Wave and Periodic Wave Solutions of a Class of Higher–Order Nonlinear Wave Equations
(Hindawi Publishing Corporation, 2015)We study the exact traveling wave solutions of a general fifth-order nonlinear wave equation and a generalized sixth-order KdV equation. We find the solvable lower-order subequations of a general related fourth-order ... -
Exact Solutions and Conservation Laws for a Generalized Double Combined sinh-cosh-Gordon Equation
(Springer, 2016)In this paper we study a generalized double combined sinh-cosh-Gordon equation, which appears in a wide range of physical applications. It admits geometric interpretation as the differential equation which determines ... -

Exact solutions and Conservation Laws of the Drinfel’d-Sokolov-Wilson System
(Hindawi Publishing Corporation, 2014)We study the Drinfel'd-Sokolov-Wilson system, which was introduced as a model of water waves. Firstly we obtain exact solutions of this system using the G'/G-expansion method. In addition to exact solutions we also construct ... -
Exact solutions for Stokes' Flow of a non-Newtonian nanofluid model: a Lie Similarity approach
(De Gruyter, 2016)The fully developed time-dependent flow of an incompressible, thermodynamically compatible non-Newtonian third-grade nanofluid is investigated. The classical Stokes model is considered in which the flow is generated due ... -
Exact Solutions of Fragmentation Equations with General Fragmentation Rates and Separable Particles Distribution Kernels
(Hindawi Publishing Corporation, 2014)We make use of Laplace transform techniques and the method of characteristics to solve fragmentation equations explicitly. Our result is a breakthrough in the analysis of pure fragmentation equations as this is the first ... -
Exact solutions of the symmetric regularized long wave equation and the Klein–Gordan–Zakharov equations
(Hindawi Publishing Corporation, 2014)We study two nonlinear partial differential equations, namely, the symmetric regularized long wave equation and the Klein-Gordon-Zakharov equations. The Lie symmetry approach along with the simplest equation and exp-function ... -
Examine medicinal plants from South Africa for suppression of Meloidogyne incognita under glasshouse conditions
(Society of Nematologists, 2020)The nematicidal activity of crudely milled powders of stems, leaves, and bulbs of Cassia abbreviata, Cissus cactiformis, Euphorbia ingens, Ipomoea kituiensis, Synadenium cupulare, Senna petersiana, Urigenia sanguinea, ... -
Examining the influence of the wine festival experience on tourists' quality of life
(Springer Verlag, 2013)Hosting events and festivals is the best way of providing the wine tourism experience. Wine festivals offer a wide range of experiences that are different from day-today living, offer a lifestyle package and are an indicator ... -

Examining the relationship between job security, compensation and training among professional sport coaches in South Africa
(LAM Publications; AJOL; Sabinet, 2013)Sport organizations are mainly in the business of providing a service - for example sport coaching. For coaches to perform at the optimal level they need, among other things, to be provided with appropriate training and ... -
Exceptional enlargement of the mitochondrial genome results from distinct causes in different rain frogs (Anura: Brevicipitidae: Breviceps)
(Hindawi, 2020)The mitochondrial (mt) genome of the bushveld rain frog (Breviceps adspersus, Brevicipitidae, Afrobatrachia) is the largest (28.8 kbp) among the vertebrates investigated to date. The major cause of genome size enlargement ... -
The exceptional VHE gamma-ray outburst of PKS 1510-089 in May 2016
(PoS, 2017)PKS 1510-089 (z=0.361) is one of only a handful of flat spectrum radio quasars that have been detected at very high energy (VHE, E > 100GeV) gamma rays. It is a very active source across the entire electromagnetic spectrum. ... -
The exceptionally powerful TeV y-ray emitters in the Large Magellanic Cloud
(AAAS, 2015)The Large Magellanic Cloud, a satellite galaxy of the Milky Way, has been observed with the High Energy Stereoscopic System (H.E.S.S.) above an energy of 100 billion electron volts for a deep exposure of 210 hours. Three ... -
Excretion of polycyclic aromatic hydrocarbon metabolites (OH-PAHs) in cattle urine in Ghana
(Elsevier, 2016)Previous studies of polycyclic aromatic hydrocarbons (PAHs) in particulate matter, soils and livers of wild rats indicated that the city centre of Kumasi, Ghana has been severely polluted with high cancer potency. Cattle ... -
Exercise increases hyper-acetylation of histones on the Cis-element of NRF-1 binding to the Mef2a promoter: implications on type 2 diabetes
(Elsevier, 2017)Exercise brings changes on the chromatin ensuing the upregulation of many genes that confer protection from type 2 diabetes. In type-2 diabetes, critical genes are down-regulated such as those involved in glucose transport ... -
Exercise-induced muscle damage: what is it, what causes it and what are the nutritional solutions?
(Taylor & Francis, 2019)Exercise-induced muscle damage (EIMD) is characterized by symptoms that present both immediately and for up to 14 days after the initial exercise bout. The main consequence of EIMD for the athlete is the loss of skeletal ... -
