Comparison of the penetration, development and reproduction of Meloidogyne graminicola, and analysis of lignin and total phenolic content in partially resistant and resistant recombinant inbred lines of Oryza sativa
(Springer, 2019)The mechanism of resistance of selected recombinant Oryza sativa inbred lines (RILs) resistant and partially resistant to Meloidogyne graminicola, and their resistant (IR78877–208-B-1-2) and susceptible (IR64, Dinorado) ... -
Comparison of the penetration, development and reproduction of Meloidogyne javanica and M. graminicola on partially resistant Oryza sativa cultivars from East Africa
(Brill, 2020)The host response to Meloidogyne javanica infection of selected Oryza sativa and NERICA (New Rice for Africa) genotypes that are commonly grown in Tanzania and East Africa was examined. The O. sativa genotypes ‘Komboka’ ... -
Comparison of the performance and durability of PEM fuel cells with different Pt-activated microporous layers
(Elsevier, 2020)We report on a comparative study of the performance level of H2/O2 PEM fuel cells in which the catalytic layers containing Pt nanoparticles were deposited on the microporous layer side of gas diffusion electrodes, using ... -

(ANSINET, 2018)Background and Objectives: The epidemic of obesity is frequently prevailing, certainly am ong pediatric inhabitants and could be influenced by environmental and heritable factors. So, the aim of this study was to ... -
A comparison of the traditional and simplified methods for water poverty index calculation
(Mediterranean Center of Social and Educational Research (MCSER), 2013)The aim of this research is to quantify the difference in the water poverty index when calculated with the traditional method, compared to the new and simplified water poverty indices. It is calculated and compared for the ... -
A comparison of the witchcraft is poison metaphor in Soweto and selected Old Testament passages
(Department of Biblical and Ancient Studies University of South Africa, 2011)African Old Testament interpretation has been asserting itself against mainstream Euro-American biblical scholarship. In doing so, various tools have been crafted, mostly in accordance with the goal of addressing the life ... -
Comparison of trauma on survivors of sexual assault and intimate partner violence in Limpopo
(AOSIS, 2014)Background: Gender-based violence is a challenge in South Africa, despite available interventions. Caring for the survivors of both forms of violence is critical for ensuring their speedy recovery. Objectives: To compare ... -
