The analysis of an ammonia/water hybrid heat pump in the ethanol production process
(North-West University, 2008)Ethanol is a renewable energy source that could decrease society's dependence on fossil fuels, while reducing greenhouse gas emissions. Producing ethanol on a small scale on South African farms could provide farmers with ... -
Artemisinin quinoline hybrid-dimers: synthesis and in vitro antiplasmodial activity
(Elsevier, 2010)Novel artemisinin–quinoline hybrid-dimers were synthesized from dihydroartemisinin and different aminoquinolines at elevated temperatures (90–110 °C). All compounds were obtained as the β-isomers and were tested against ... -
Artemisinin–quinoline hybrids : design, synthesis and antimalarial activity
(North-West University, 2013)Introduction - Malaria is a major global health problem, with more than 500 million reported cases and at least 1 million deaths each year. The main problem with malaria control is the emerging drug resistance. Plasmodium ... -
In vitro efficacy of synthesized artemisinin derivatives against Leishmania promastigotes
(Elsevier, 2020)Leishmaniasis is a neglected tropical disease affecting thousands worldwide, especially in developing countries where it co-exists with malaria. Only a handful of drugs are clinically available to treat the disease, but ... -
Polyphonic conversations between novel and film : Heart of darkness and Apocalypse now ; Na die geliefde land and Promised land
(North-West University, 2006)This dissertation attempts a Bakhtinian analysis of the polyphonic dialogue between Joseph Conrad's Heart of Darkness, Francis Ford Coppola's Apocalypse Now, Karel Schoeman's Na die Geliefde Land and Jason Xenopoulos' ... -
Synthesis, in vitro antimalarial activities and cytotoxicities of amino-artemisinin-ferrocene derivatives
(Elsevier, 2018)Novel derivatives bearing a ferrocene attached via a piperazine linker to C-10 of the artemisinin nucleus were prepared from dihydroartemisinin and screened against chloroquine (CQ) sensitive NF54 and CQ resistant K1 and ... -
Synthesis, in vitro antiplasmodial activity and cytotoxicity of a series of artemisininetriazine hybrids and hybrid-dimers
(Elsevier, 2014)A series of artemisininetriazine hybrids and hybrid-dimers were synthesized and their in vitro antimalarial activity against the chloroquine sensitive (CQS), the gametocytocidal (NF54) and the choroquine resistant (CQR) ...
