Regulation and characterization of the nitrogen assimilatory gene cluster in Clostridium acetobutylicum P262 by Stutz, Helen

“…The identity of the gltA and gltB genes were functionally confirmed by complementation studies involving their co-expression from separate constructs in an E. coli glutamate auxotroph (strain: Mx:3004), which restored the ability of this mutant to grow with ammonia as the sole source of nitrogen. …”

Exploring the factors at play to make wastewater biorefineries a reality by Verster, Bernelle

“…Each reactor group is considered in detail and evaluated with regards to its suitability to the wastewater biorefinery, leading to selection of appropriate reactor designs. Stoichiometric mass balances of all unit operations are established, showing the material value flows, and combined to model this multi-bioreactor approach. …”

Elephant space use in relation to ephemeral surface water availability in the eastern Okavango Panhandle, Botswana by Makati, Anastacia

“…Mean daily distances were computed to investigate the effect of season on elephant daily distances and the distances ranged between 5km and 6.8km in the late wet and in the early wet and late dry season respectively. The Resource Selection Function (RSF) analysis shows that water adjacent sites are preferred over distant ones and both sexes prefer areas with high NDVI, with this preference being more pronounced in males. …”

A geochemical and stable isotope study of some rocks from the Bandelierkop formation, southern marginal zone of the Limpopo Belt, South Africa( vol.1 Text) by Vennemann, Torsten Walter

“…Peak metamorphic conditions of 730°C + 65°C at pressures of 6.1 ± 1.5 kbars may be deduced from a careful application of several cation thermometers and barometers on selected mineral analyses. A rigorous application of garnet-biotite thermometry to the pelitic rocks indicates that the transition from orthoamphibole gneisses in the south to orthopyroxene-bearing rocks in the north of the SMZ terrane, is a function of changing biotite composition and/or decreasing water activities rather than an increase in metamorphic temperatures. …”
