Contending with unequal and privileged access to natural resources and land in the Okavango Delta, Botswana
(Blackwell http://www.wiley.com/10.1111/j.1467-9493.2008.00332.x, 2008)
This paper reviews how state policy and regulatory instruments, including protected area alienations
and concessions, have altered or denied the access to land and natural livelihood resources
of the indigenous Basarwa ...
Gravity anomaly patterns in the south-central Zimbabwe Archaean craton and their geological interpretation
(Elsevier Science Ltd. www.elsevier.com/locate/jafrearsci, 2008)
The granite-greenstone terrain of south-central Zimbabwe, encompassing the Belingwe (Mberengwa) greenstone belt and sections of
the Great Dyke, provides important constraints on models for the evolution of the Zimbabwe ...
Phase segregation in Pb:GeSbTe chalcogenide system
(EDP Sciences. http://www.epjap.org/, 2008)
Effect of Pb substitution on the amorphous-crystalline transformation temperature, optical band
gap and crystalline structure of Ge2Sb2Te5 has been studied. In Pb:GeSbTe chalcogenide films prepared by
thermal evaporation, ...
Electron-LO-phonon scattering near a current-carrying core
(Elsevier Science Ltd. http://www.elsevier.com/wps/find/journaldescription.cws_home/622948/description#description, 2008)
A calculation is presented on the scattering rates of electrons via the bulk spectrum of longitudinal
optical phonons near a current-carrying core of radius R employing the Frohlich interaction Hamiltonian.
The electrons ...
Mycoflora and natural occurrence of aflatoxins and fumonisin B1 in cassava and yam chips from Benin, West Africa
(Elsevier B.V. www.elsevier.com/locate/ijfoodmicro, 2008)
The presence of fungi, aflatoxins and fumonisin B1 in cassava and yam chips (during 28 processing and storage) were evaluated during two
consecutive seasons in two agroecological zones of Benin (Northern Guinea Savannah, ...
Aeromagnetic and Landsat TM structural interpretation for identifying regional groundwater exploration targets, south-central Zimbabwe Craton
(Elsevier Science Ltd. www.elsevier.com/locate/jappgeo, 2008)
Aeromagnetic (AM) and Landsat Thematic Mapper (TM) data from the south-central Zimbabwe Craton have
been processed for the purpose of regional structural mapping and thereby to develop strategic models for
groundwater ...
Reaction of a bulky phosphite with [Ru3(CO)12]: the molecular structure of one of the decomposition products
(Elsevier B.V. www.elsevier.com/locate/ica, 2008)
Mono- and bis-substituted phosphite complexes [Ru3(CO)12 x Lx] (L = tris(2,4-di-tert-butylphenyl) phosphite; x = 1, 2) were synthesized
by simple substitution reactions, and were characterized by spectroscopic methods. ...
Effect of annealing on the structural, optical and electrical properties of ITO films by RF sputtering under low vacuum level
(Elsevier Ltd, 2008)
Indium tin oxide (ITO) thin films were prepared by RF sputtering of ceramic ITO target in pure argon
atmosphere at a high base pressure of 3 10 4mbar without substrate heating and oxygen admittance.
The use of pure argon ...
Decrease in hydraulic conductivity in saturated soil columns and particle release associated with self-filtration in saturated soil columns
(Elsevier http://www.linkinghub.elsevier.com/retrieve/pii/S0016706108001365, 2008)
The dynamics of the process of self-filtration in soil columns have been evaluated for two soils with different
structural cohesion (Balkuling agricultural soil and a mining residue) by carrying out experiments focusing
on ...
Using a pore-scale model to quantify the effect of particle re-arrangement on pore structure and hydraulic properties
(Wiley http://www.interscience.doi.wiley.com/10.1002/hyp.6299, 2008)
A pore-scale model based on measured particle size distributions has been used to quantify the changes in pore space geometry
of packed soil columns resulting from a dilution in electrolyte concentration from 500 to 1 ...
