Analysis of nature-based treatment of surface water runoff from an informal settlement to irrigate vegetables
… analyse and make a comparative analysis of the physicochemistry of the soil, and nutrient concentration in crops following irrigation with biofiltration-treated surface runoff from IS. Municipal Treated Water (MTW) was used alongside Biofiltration-treated Water (BTW) to irrigate crops for nine …

Hydrochemical dynamics on sub-Antarctic Marion Island
… Cl⁻ , SO4²⁻, NO³⁻). In addition, stream water physicochemistry (pH, water temperature, dissolved oxygen and total dissolved solids) was monitored in situ at a single site in the stream at 5 minute resolution for the duration of the field campaign. Monthly precipitation δ²H and δ¹⁸O had mean …

The impact of silver nanoparticles on plant physiology
… of applications and products due to their novel physicochemistry. Hence it is inevitable that ENPs will enter the environment at an increasing rate over the coming years. The consequential impact following interaction between ENPs with plants and soil microbial communities is of great concern …

Recovery of southern Appalachian streams from historical agriculture
… catchments, but the other aspects of stream physicochemistry remained elevated or changed due to historical agriculture. I expected biological community structure and ecosystem processes to reflect these altered conditions in streams with current and historical agriculture. Higher …

Tin Sensitization For Electroless Plating
… reagent concentration, exposure time, substrate physicochemistry, and post-exposure conditions on surface tin(II) content were evaluated. Aqueous immersion post-reaction doubled tin(II) surface concentration compared to drying in nitrogen before a two-minute air exposure. In Chapter V the 2D …

Microbial nitrogen-cycling and cooperation in the terrestrial subsurface
… was prevalent regardless of site-specific physicochemistry, but pathway relative abundances differed. Anammox helps to drive N loss from aquatic systems, and is expected to be associated with low oxygen and carbon availability. While anammox-associated bacteria (class Brocadiae) diversity …

Características microbiológicas, físico-químicas e sensoriais de filés de tilápias (Oreochromis niloticus) conservados em atmosferas modificadas sob refrigeração
Estudou-se o efeito de diferentes atmosferas (vácuo, 100% CO + vácuo, 1% CO + 99% CO2) sobre a qualidade microbiológica, química, cor objetiva no sitema CIELab e sensorial de filés de tilápias (Oreochromis niloticus) estocados a 2 ± 1 ºC. Os resultados foram contrastados com aqueles de filés …
