Mantle structure and composition to 800-km depth beneath southern Africa and surrounding oceans from broadband body waves
(Elsevier Science Ltd. www.elsevier.com/locate/lithos, 2003)
Average one-dimensional P and S wavespeed models from the surface to depths of 800 km were derived for the southern
African region using travel times and waveforms from earthquakes recorded at stations of the Kaapvaal and ...
Pn arrivals and lateral variations of Moho geometry beneath the Kaapvaal craton
(Elsevier Science Ltd. www.elsevier.com/locate/lithos, 2003)
Pn arrivals from mining-induced earthquakes on the edge of the Witwatersrand basin show that the P wavespeeds in the
uppermost mantle are almost constant throughout most of the Kaapvaal craton. The presence of only small ...
Optimising growth conditions for the pectinolytic activity of Kluyveromyces wickerhamii by using response surface methodology
(Elsevier / www.elsevier.com/locate/ijfoodmicro, 2003)
This present study was undertaken to find optimum conditions of pH, temperature and, period of incubation for the
pectinolytic activity of Kluyveromyces wickerhamii isolated from rotting fruits and to assess the effect ...
The influence of the Tbetta level upon fluorescence and laser properties of aromatic compounds
(Elsevier Science Ltd http:www.elsevier.com/locate/saa, 2003)
Please refer to the attached article for an ABSTRACT. The abstract was not uploaded here due to formula appearance problem in UBRISA.
Comprehensive study of solar conditions in Mozambique: the effect of trade winds on solar components
(Elsevier Science Ltd. www.elsevier.com/locate/renene, 2003)
A new algorithm to simulate all solar components and optimum slopes, Bopt, based on new
models for direct normal beam and diffuse radiation and an analytical model to predict Bopt,
developed at the University of Botswana ...
Influence of weak and strong donor groups on the fluorescence parameters and the intersystem crossing rate constant
(Elsevier Science Ltd. www.elsevier.com/locate/saa, 2003)
Please refer to the attached article for an ABSTRACT. The abstract was not uploaded here due to formula appearance problem in UBRISA.
Bivarate models: relationships between solar irradiation and either sunshine duration or extremum temperatures
(Elsevier Science Ltd. www.elsevier.com/locate/renene, 2003)
The Republic of Botswana is one of the sunniest countries in Southern Africa. It has very little cloud cover, insufficient rainfall, very low humidity, and very low wind speed throughout the year for most parts of the ...
Antioxidant activity of prenylated flavonoids from the West African medicinal plant Dorstenia mannii
(Elsevier Science Ireland Ltd. www.elsevier.com/locate/jethpharm, 2003)
The antioxidant activities of three prenylated flavonoids from Dorstenia mannii (6,8-diprenyleriodictyol, dorsmanin C and dorsmanin F)
were compared to the common, non-prenylated flavonoid, quercetin. The prenylated ...
Phenylpropanoid glycosides of Gnidia polycephala
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2003)
Two phenylpropanoid glucosides, 2-O-b-d-glucosyloxy-4-methoxybenzenepropanoic acid and its methyl ester, together with
syringin and adicardin were isolated from the stem of Gnidia polycephala and characterized by physical ...
Influence of seasonal flooding on soil total nitrogen, organic phosphorus and microbial populations in the Okavango Delta, Botswana
(Journal of Arid Environments. http://www.elsevier.com/wps/find/journaldescription.cws_home/622855/description#description, 2003)
The effect of flooding on soil total nitrogen, phosphorus and microbial
population in different vegetation zones (floodplain, island and woodland)
and profile depth (0?1, 0?5, 2?0, 3?0, 4?0 and 5?0m) of the Okavango ...
