High 16S rDNA bacterial diversity in glacial meltwater lake sediment, Bratina Island, Antarctica
(Springer Verlag, 2003)
The microbial diversity in maritime meltwater
pond sediments from Bratina Island, Ross Sea, Antarctica
was investigated by 16S rDNA-dependent
molecular phylogeny. Investigations of the vertical
distribution, phylogenetic ...
A CHANDRA STUDY OF TEMPERATURE SUBSTRUCTURES IN INTERMEDIATE-REDSHIFT GALAXY CLUSTERS
(2009)
By analyzing the gas temperature maps created from the Chandra archive data, we reveal the prevailing existence of temperature substructures on ∼ 100 h −1 70 kpc scales in the central regions of nine intermediate-redshift ...
Asynchronous video telephony for the Deaf
(Telkom, 2007)
The South African Deaf community has very limited telephony options. They prefer to communicate in sign language, a visual medium. Realtime video over Internet Protocol is a promising option, but in reality, the quality ...
Telecommunications bridging between deaf and hearing users in South Africa
(2004)
This paper presents a description of telecommunications for Deaf people in South Africa by contrasting the situation in the developed world. We explain the main motivations for providing a locally appropriate solution. ...
Using voice over IP to bridge the digital divide: a critical action research approach
(Telkom, 2003)
There is a great disparity between those who have access to Information and Communication Technologies (ICTs) and those that do not. This phenomenon forms part of the Digital Divide. Many ICTs may be used to help overcome ...
SoftBridge in action: the first Deaf telephony pilot
(Telkom, 2003)
Following on several partial prototypes, we built an automated Deaf Telephony bridging application with the SoftBridge platform. The SoftBridge performs multi-modal bridging in real-time using Text-to-Speech (TTS) and ...
The role of Outcome Mapping in developing a rural telemedicine system
(International Information Management Corporation, 2008)
We describe the use of Outcome Mapping to guide the design of a rural telemedicine consultation system in South Africa. While Outcome Mapping was not primarily intended to guide design, we show that it tied in well with a ...
Video observations on the habitat association of demersal nekton in the mid-shelf benthic environment off the Orange River mouth
(NISC and Taylor & Francis, 2000)
A semi-quantitative assessment is made of the animals observed in archived videotapes taken from the research submersible Jago, during diamond mining and exploratory surveys off the mouth of the Orange River on the west ...
Growth of market-size abalone (Haliotis midae) fed kelp (Ecklonia maxima) versus a low-protein commercial feed
(Taylor & Francis, 2008)
The growth of grow-out abalone fed on kelp, with ca. 10 % dry weight protein
content, was compared with that of those fed a new ,ca. 26 % protein, commercial
feed in a flow-through system on a South African west coast ...
Observations on the ecology of Pleurobrachia pileus (Ctenophora) in the southern Benguela ecosystem
(NISC (Pty) Ltd and Taylor & Francis, 2003)
The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995. The population was ...
