Luminescence-laser classification of heteroaromatic and aromatic compounds
(Elsevier Science BV; www.elsevier.com/locate/saa, 2002-01-15)
[Please note that the mathematical symbols have not transposed into this abstact].The luminescent and laser properties of heteroaromatic and aromatic compounds are reviewed and discussed on the basis of all possible mutual ...
Renewable energy education in Botswana: needs, status and proposed training programs
(Elsevier Science Ltd. http://www.sciencedirect.com/science/journal/09601481, 2002-01)
Lack of trained manpower for repair and maintenance of solar energy devices in Botswana
has resulted in failure of devices, loss of revenue, and dwindling of consumer faith in solar
technologies. The government of Botswana ...
Origin and palaeo-environments of calcareous sediments' in the Moshaweng dry valley, Southeast Botswana
(John Wiley & Sons, Ltd. http://www3.interscience.wiley.com/journal/117935722/grouphome/home.html, 2002)
Quaternary sedimentation in the Moshaweng dry valley of southeastern Botswana is evaluated on the basis of geomorphological evolution and sedimentological analyses. Stratigraphic evidence reveals an 'upper surface (1095 ...
The current-induced critical field of a type II superconducting cylindrical filament
(Elsevier Science Ltd. www.elsevier.com/locate/physc, 2002-08-15)
The azimuthal surface nucleation field of an infinitely long type II superconducting cylindrical filament is calculated
from the linearized Ginzburg-Landau equation for the order parameter. A current is thought to be ...
Stochastic models for sunshine duration and solar irradiation
(Elsevier Science Ltd: http://www.elsevier.com/wps/find/journaldescription.cws_home/969/description#description, 2002)
Abstract
Harmonic analysis of sunshine duration and solar irradiation measured at Sebele, Botswana is carried out. The data used consists of the monthly averages and the Julian-days averages of sunshine duration and solar ...
The theory of attenuated total reflection by surface polaritons on corrugated semi-infinite media
(Elsevier Science Ltd. www.elsevier.com/locate/physb, 2002-02)
The experimental techniques of attenuated total reflection and grating-coupling were originally employed separately
as probes for surface polaritons. However, as far back as the mid-1970s, some value was found in actually ...
Gravity evidence for a larger Limpopo Belt in southern Africa and geodynamic implications
(Royal Astronomical Society. http://www.wiley.com/bw/journal.asp?ref=0956-540X&site=1, 2002)
The Limpopo Belt of southern Africa is a Neoarchean orogenic belt located between two older Archean provinces, the Zimbabwe craton to the north and the Kaapvaal craton to the south. Previous studies considered the Limpopo ...
The P wavespeed structure below and around the Kaapvaal craton to depths of 800 km, from traveltimes and waveforms of local and regional earthquakes and mining-induced tremors
(Oxford University Press, https://academic.oup.com/gji, 2002-10-01)
An average P-wavespeed model from the surface to depths of 800 km was derived for southern Africa using traveltimes and waveforms from earthquakes recorded at stations of the Kaapvaal and South African National networks. ...
