Microfiltration of Synthetic Metal Working Fluids Using Aluminum Oxide Membranes
… by the rate of contaminant build-up in the MWF. Microbiological population growth can grow to potentially hazardous levels in extremely short time-scales. Membrane filtration systems designed to control microbial populations must remove microbes from the MWF at a rate faster than population …

Justificación del empleo de nuevos indicadores biológicos en relación con la calidad de las aguas
… be reused once it was subject to treatment. The microbiological parameters are of particular importance in the current regulations, but they may not assure the quality of treated residual waters. The present work is driven by the necessity of proposing new biological bacterial indicators to be …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
… into soil altered the chemical, physical, and microbiological parameters of the pasture. Notably, Pseudomonas community composition (species richness and diversity), soil organic matter content, and carbon recalcitrance were associated with enhanced suppression of damping-off disease. …

Rooftop Collected Rainwater Quality and Vegetation Impact: Field Work in Lagos, Nigeria, and the Related Experimental and Numerical Studies
Water scarcity is a significant issue in the underdeveloped and developing countries, and harvested rainwater has the potential of being an improved source of water for consumption. Since many residents in both rural and urban settings in Nigeria rely on harvested rainwater as a source of water for …
