Theoretical study of properties of Cs2Cl+, CsCl2−, Cs3Cl2+, and Cs2Cl3− ions: Effect of Basis set and Computation Method
(Rwanda Journal, 2012-07)
Theoretical study of properties of Cs2Cl+, CsCl2−, Cs3Cl2+ and Cs2Cl3− ions has been performed using the density functional theory (DFT/B3LYP) and the second order Møller-Plesset perturbation theory (MP2). Two triple-zeta ...
The Last Will Be First: Water Transfers from Agriculture to Cities in the Pangani River Basin, Tanzania
(Water Alternatives, 2012-10)
Water transfers to growing cities in sub-Sahara Africa, as elsewhere, seem inevitable. But absolute
water entitlements in basins with variable supply may seriously affect many water users in times of water scarcity.
This ...
The Role of Statutory and Local Rules in Allocating Water between Large- and Small-Scale Irrigators in an African River Catchment
(Elsevier, 2012-01)
This paper presents a case study of large- and small-scale irrigators negotiating for access to water from Nduruma River in the Pangani River Basin, Tanzania. The paper shows that despite the existence of a formal statutory ...
The dynamics between water asymmetry, inequality and heterogeneity sustaining canal institutions in the Makanya catchment, Tanzania
(IWA Publishing, 2012-10-01)
It has been suggested that the collective action needed for integrated water management at larger spatial scales could be more effective and sustainable if it were built, bottom-up, on the nested arrangements by which local ...
Synthesis and characterization of micrometer-sized silica aerogel nanoporous beads
(Elsevier, 2012-08-15)
Here we report the preparation of micrometer-sized highly nanoporous, relatively trasperant silica aerogel beads with high surface area as well as large pore volume with sizes ranging from 165 to 395 μm. The wet micrometer-sized ...
Synthesis of mesoporous silica with superior properties suitable for green tire
(Elsevier, 2012-09-25)
In this article we report synthesis of mesoporous silica with superior properties for application in green tire (environmentally friendly tire) as filler. The synthesis was done using a newly innovated apparatus which ...
Biodiesel production by sulfated mesoporous titania–silica catalysts synthesized by the sol–gel process from less expensive precursors
(Elsevier, 2012-11-21)
A sulfated titania–silica composite (S-TSC) was obtained through surface modification of mesoporous
titania–silica composite synthesized using less expensive precursors; titanium oxychloride and sodium
silicate as titania ...
Win-win-win wastewater treatment: affordable hygienic solutions that enable reuse of water and nutrients to sustain food security and support mitigation of climate change.
(International Conference on Water Management Issues in Africa, At Mauritius, 2012-03)
The lack of access to safe drinking water and hygienic sanitation is still a major health treat
for many Africans. Especially in poor communities the situation is threatening as these
vulnerable communities are often ...
