A hydrogeomorphological approach to quantification of groundwater discharge to streams in South Africa
(Water Research Commission, 2002)
In South Africa, the flow requirements for maintaining the normal functioning of aquatic ecosystems is termed the “ecological
reserve”, and these should be determined when a licence application for water allocation is ...
Capture zone simulation for boreholes located in fractured dykes using the linesink concept
(Water Research Commission, 2002)
Delineation of capture zones for groundwater source protection is normally performed by using numerical codes which are based
on the porous medium flow equation. However, boreholes are often sited in or along permeable ...
Efficient molecular cloning of environmental DNA from geothermal sediments
(Kluwer Academic Publishers, 2002)
An efficient and simple method for constructing an environmental library using mechanically sheared DNA obtained
directly from geothermal sediments is presented. The method is based on blunt-end modification of DNA
fragments ...
The search for the ideal biocatalyst
(Nature Publishing Group, 2002)
While the use of enzymes as biocatalysts to assist in the industrial manufacture of fine chemicals and pharmaceuticals has enormous potential, application is frequently limited by evolution-led catalyst traits. The advent ...
SoftBridge: an architecture for building IP-based bridges over the digital divide
(Telkom, 2002)
Users and computing equipment have varying capabilities that include the abilities to exchange text and audio, engage in high bandwidth communication, etc. As the technological options increase, e ective communication ...
Telgo323: an H.323 Bridge for deaf telephony
(Telkom, 2002)
We have developed a prototype bridge that relays text and speech between Teldem, a text telephone for the Deaf, and a standard telephone or H.323 endpoint. Telgo323 uses modified H.323 media gateways and open source Text ...
Antarctic Dry Valley mineral soils contain unexpectedly high levels of microbial biomass
(Springer Verlag, 2002)
We have applied bioluminescent ATP detection
methods to microbial enumeration in Antarctic Dry Valley
mineral soils, and validated our ATP data by two independent
methods. We have demonstrated that ATP measurement
is ...
Biodegradation of high-concentration isopropanol by a solvent-tolerant thermophile, Bacillus pallidus
(Springer Verlag, 2002)
The aerobic biodegradation of high-concentration,
to 24 g l
–1
, 2-propanol (IPA) by a thermophilic isolate
ST3, identified as
Bacillus pallidus
, was successfully carried
out for the first time. This solvent-tolerant
B. ...
The genetic organisation of a 2,966 basepair DNA fragment of a Single Capsid Nucleopolyhedrovirus isolated from Trichoplusia ni
(Springer Verlag, 2002)
In order to investiagte the genomic organization of the Trichoplusia ni Single Capsid Nucleoplyhedrovirus (TnSNPV) , a 2,966 base pairs (bp) genomic fragment was sequenced. The fragment was found to contain five open reading ...
Development of infectious transcripts and genome manipulation of black queen-cell virus of honey bees
(Microbiology Society, 2002)
The South African isolate of Black queen-cell virus (BQCV), a honey bee virus, was previously found
to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a
5«-proximal ORF encoding ...
