Endophytic colonization of Vicia faba and Phaseolus vulgaris (Fabaceae) by fungal pathogens and their effects on the lifehistory parameters of Liriomyza huidobrensis (Diptera: Agromyzidae)
(ELSEVIER, 2013)Ten fungal isolates belonging to the genera Beauveria (3), Hypocrea (1), Gibberella (1), Metarhizium (2), Trichoderma (1) and Fusarium (2) were evaluated in the laboratory to determine whether they could become endophytic ... -
Energy intake and energy expenditure of preprofessional female contemporary dancers
(PLoS, 2017)Many athletes in aesthetic and weight dependent sports are at risk of energy imbalance. However little is known about the exercise and eating behaviours of highly trained dance populations. This investigation sought to ... -
Energy loss in intergalactic pair beams: particle-in-cell simulation
(EDP Sciences, 2016)Aims. The change in the distribution function of electron-positron pair beams determines whether GeV photons can be produced as secondary radiation from TeV photons. We will discuss the instabilities driven by pair ... -
Energy policy, air quality, and climate mitigation in South Africa: the case for integrated assessment
(Springer, 2018)Background and significance: South Africa reports approximately 20,000 premature deaths due to air pollution annually. Policy in South Africa has typically addressed greenhouse gas emissions, energy supply, and air quality ... -
Energy spectra of carbon and oxygen with HELIOS E6: radial gradients of anomalous cosmic ray oxygen within 1 AU
(EDP Sciences, 2018)Context. Anomalous cosmic rays (ACRs) are well-suited to probe the transport conditions of cosmic rays in the inner heliosphere.We revisit the HELIOS data not only in view of the upcoming Solar Orbiter experiment but also ... -
Energy spectrum of cosmic-ray electrons at TeV energies
(APS, 2008)The very large collection area of ground-based γ-ray telescopes gives them a substantial advantage over balloon or satellite based instruments in the detection of very-high-energy (>600 GeV) cosmic-ray electrons. Here we ... -
Engineering and expression of a human rotavirus candidate vaccine in Nicotiana benthamiana
(BioMed Central, 2015)Background: Human rotaviruses are the main cause of severe gastroenteritis in children and are responsible for over 500 000 deaths annually. There are two live rotavirus vaccines currently available, one based on ... -
Engineering semantic web services for government business processes automation
(Springer, 2015)Web Services (WS) technology does not allow automatic discovery and execution of services in the current distributed and complex business environments. Semantic Web Services (SWS) overcome this limitation by adding semantic ... -
Engineering students at the Vaal University of Technology : Analysing learning style preferences
(IBIMA, 2010)What are the different learning style preferences of students at the Vaal University of Technology,and how is it possible to address all the learning styles simultaneously? Each individual has a distinctive preference ... -
Enhanced corticospinal excitability and volitional drive in response to shortening and lengthening strength training and changes following detraining
(Frontiers Media, 2017)There is a limited understanding of the neurological adaptations responsible for changes in strength following shortening and lengthening resistance training and subsequent detraining. The aim of the study was to investigate ... -
Enhanced H I profile asymmetries in close galaxy pairs
(Oxford Univ Press, 2019)Analysing the quantified H I profile asymmetries of galaxies in different environments, we explore not only the prevalence of asymmetry in H I profiles, but also the possibility of using H I profile asymmetries to trace ... -
Enhanced microbial hydrocarbon biodegradation as stimulated during field-scale landfarming of crude oil-impacted soil
(Elsevier, 2019)The study investigated microbial population dynamics and petroleum hydrocarbon degradation during 56-day landfarming bioremediation of crude oil-polluted soil at a Community in Niger Delta Nigeria. Landfarming involved the ... -
Enhanced oral bioavailability of the antiretroviral efavirenz encapsulated in poly(epsilon–caprolactone) nanoparticles by a spray–drying method
(NCBI, 2014)AIM: To encapsulate efavirenz (EFV) within poly(epsilon-caprolactone) (PCL) nanoparticles (NPs) and compare the oral pharmacokinetics with that of EFV-loaded micelles and pure EFV NPs. MATERIALS & METHODS: EFV-loaded ... -
Enhancing charge separation and photocatalytic activity of cubic SrTiO3 with Perovskite-type materials MTaO3 (M=Na, K) for environmental remediation: a first-principles study
(Wiley, 2017)Due to increasingly global environmental and energy crises, visible light semiconductor photocatalyst with a tunable bandgap and optical properties have received attention. This study aid in the design of bifunctional ... -
Enhancing EIA systems in developing countries: a focus on capacity development in the case of Iran
(Elsevier, 2019)Sensitivity to an Environmental Impact Assessment (EIA) system's context is a precondition for being able to suggest recommendation to improving that system. Most recommendations for developing countries take inspiration ... -
Enhancing participatory evaluation of land management through photo elicitation and photovoice
(Taylor & Francis, 2015)Land management evaluation can be made more relevant and holistic by incorporating local knowledge and perspectives. We examined whether photo elicitation and photovoice could enhance semi-structured interviews in capturing ... -
