The final BGE consisted of 20 mM phosphoric acid, 40 mM SDS and 12 mM -cyclodextrin (pH 2.2) using reverse polarity with a voltage of −17.5 kV. Samples were injected electrokinetically at −5 kV for 3 s for the qualitative analysis and hydrodynamically at 20 mbar for 0.6 s for the quantitative assay.

Results of the investigation indicated that the microheterotrophs represented the most important consumers of bacteria and chlorophyll (chl)-a <5.0 μm. The low impact of the mesozooplankton on the bacteria and chl-a <5.0 μm during the study appeared to be related to the inability of the larger zooplankton to feed efficiently on small particles. During those periods when total chl-a concentration was dominated by picophytoplankton (<2.0 μm) and microphytoplankton (>20 μm), mesozooplankton were unable to feed efficiently on the chl-a due to feeding constraints. In response to the unfavorable size structure of the phytoplankton assemblages, mesozooplankton appeared to consume the microheterotrophs. The negative impact of the mesozooplankton on the microheterotrophs resulted in a decrease in the impact of these organisms on the bacteria and the chl-a <5.0 μm. This result is consistent with the predator-prey cascades. On the other hand, when the total chl-a was dominated by nanophytoplankton (2–20 μm), mesozooplankton were able to feed directly on the phytoplankton. Results of the study indicate that size structure of the phytoplankton assemblages within estuaries plays an important role in mediating the trophic interactions between the various components of the plankton food web.]]> Thu 25 Apr 2024 15:44:49 SAST ]]> Comparison of satellite rainfall data with observations from gauging station networks https://commons.ru.ac.za/vital/access/manager/Repository/vital:7079 Thu 16 May 2024 08:33:43 SAST ]]> A generic database and spatial interface for the application of hydrological and water resource models https://commons.ru.ac.za/vital/access/manager/Repository/vital:7080 Thu 16 May 2024 08:33:04 SAST ]]> Oceanographic environment of the Sodwana Bay coelacanths (Latimeria chalumnae), South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7156 Thu 15 Jul 2021 21:37:35 SAST ]]> African Coelacanth Ecosystem Programme: An overview of the conference contributions https://commons.ru.ac.za/vital/access/manager/Repository/vital:7127 Thu 15 Jul 2021 21:37:33 SAST ]]> Language and learning science in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7023 Thu 13 May 2021 06:50:26 SAST ]]> Commentary: Negotiating distant influences: globalization and broadcasting policy reforms in Zambia and South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:6325 Thu 13 May 2021 06:42:43 SAST ]]> Lattice-valued continuous convergence is induced by a lattice-valued uniform convergence structure https://commons.ru.ac.za/vital/access/manager/Repository/vital:6824 Thu 13 May 2021 06:39:33 SAST ]]> Alternative media: a viable option for Southern Africa? https://commons.ru.ac.za/vital/access/manager/Repository/vital:6328 Thu 13 May 2021 06:22:20 SAST ]]> Study South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:28754 Thu 13 May 2021 04:19:32 SAST ]]> The South African coelacanths — an account of what is known after three submersible expeditions https://commons.ru.ac.za/vital/access/manager/Repository/vital:7131 Thu 13 May 2021 04:10:36 SAST ]]> Interactions of fishes with particular reference to coelacanths in the canyons at Sodwana Bay and the St Lucia Marine Protected Area of South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:7130 Thu 13 May 2021 03:38:40 SAST ]]> Fishes of the deep demersal habitat at Ngazidja (Grand Comoro) Island, Western Indian Ocean https://commons.ru.ac.za/vital/access/manager/Repository/vital:7128 Thu 13 May 2021 03:09:03 SAST ]]> Critical media literacy: a design for the future https://commons.ru.ac.za/vital/access/manager/Repository/vital:6331 Thu 13 May 2021 01:34:41 SAST ]]> Rhodes University Graduation Ceremony 2006 https://commons.ru.ac.za/vital/access/manager/Repository/vital:8141 Thu 13 May 2021 00:20:32 SAST ]]> The effect of Ge, Si and Sn phthalocyanine photosensitizers on cell proliferation and viability of human oesophageal carcinoma cells https://commons.ru.ac.za/vital/access/manager/Repository/vital:56241 Thu 08 Sep 2022 22:05:35 SAST ]]> Electropolymerizable iron (III) and cobalt (II) dicyanophenoxy tetraphenylporphyrin complexes https://commons.ru.ac.za/vital/access/manager/Repository/vital:56236 Thu 08 Sep 2022 21:56:50 SAST ]]> Comparative electrochemistry and electrocatalytic activities of cobalt, iron and manganese phthalocyanine complexes axially co-ordinated to mercaptopyridine self-assembled monolayer at gold electrodes https://commons.ru.ac.za/vital/access/manager/Repository/vital:56234 MnPc > CoPc. This finding is remarkable as it suggests that the success of using this method of self-assembling of MPc onto gold electrode is largely dependent on the bond distance between the pyridine linker and the central metal of the MPc; the shorter the distance, the faster the co-ordination and the better the electrocatalytic properties towards L-cysteine and thiocyanate. Thus, the superiority of FePc-based SAM over those of the MnPc and CoPc, has been proposed to be the result of the more favorable axial co-ordination properties of FePc with pyridine (i.e. shorter Fe–N(pyridine) bond length.]]> Thu 08 Sep 2022 21:51:41 SAST ]]> Comparative efficiency of immobilized non-transition metal phthalocyanine photosensitizers for the visible light transformation of chlorophenols https://commons.ru.ac.za/vital/access/manager/Repository/vital:56233 SiPcSmix > SnPcSmix > ZnPcSmix > GePcSmix > ZnPcS4 > AlPcSmix > AlOCPc > AlPcS4.
