Comparative study of morphology, morphometrics, reproductive fitness on carrot discs and pathogenicity on musa genotypes of Radopholus Similis Philippine populations
(ISSAAS, 2019)Comparative studies were conducted on three Radopholus similis populations collected in Quezon, Laguna and Davao, Philippines from 2008 to 2010. For the first time, morphological and morphometrical characteristics of the ... -
Comparative study of the dissociative ionization of 1,1,1-trichloroethane using nanosecond and femtosecond laser pulses
(MDPI, 2010)Changes in the laser induced molecular dissociation of 1,1,1-trichloroethane (TCE) were studied using a range of intensities and standard laser wavelengths with nanosecond and femtosecond pulse durations. TCE contains ... -
A comparative study of the flora and soils of Great Duck and Little Duck Islands, Maine, USA
(New England Botanical Club, 2016)Strong environmental gradients and varied land-use practices have generated a mosaic of habitats harboring distinct plant communities on islands on the coast of Maine. Botanical studies of Maine's islands, however, are ... -
Comparative time-series analysis of MeV electron data by Ulysses and Pioneer 10/11 in the Jovian magnetosphere
(Copernicus Publications, 2013)The dynamics of the Jovian magnetosphere is dominated by the planet’s fast rotation with a period of 10 h.Within the magnetosphere, this periodicity can in particular be seen in the temporal variation of the spectral index ... -
Comparing algorithms to disaggregate complex soil polygons in contrasting environments
(Elsevier, 2019)In South Africa, the only soil resource available with full spatial coverage is the national resource inventory. Disaggregating this polygon-based inventory, is thus a logical step to create more detailed soil maps covering ... -
