On the molecular basis of fouling resistance
Web3.1.1.2 Membrane resistance. The membrane resistance (Rm) or its inverse quantity, the membrane conductance ( Gm ), reflects the ion’s ability to penetrate the membrane. When there is no potential difference across the membrane, or the membrane is said to be short-circuited, the ionic flux occurs exclusively by diffusion, so the membrane ... WebThe Concept of Fouling. James G. Speight PhD, DSc, in Fouling in Refineries, 2015 1.4.3 Corrosion Fouling. Corrosion fouling is fouling deposit formation as a result of the corrosion of the substrate metal of heat transfer surfaces or reactor surfaces. In this type of fouling, corrosion occurs first and initiates fouling whereas under-deposit corrosion …

WebThe cost-effective and stable operation of an anaerobic ceramic membrane bioreactor (AnCMBR) depends on operational strategies to minimize membrane fouling. A novel strategy for backwashing, filtration and relaxation was optimized for stable operation of a side stream tubular AnCMBR treating domestic wastewater at the ambient temperature. … WebThe fouling propensity of single molecules, as opposed to bulk protein solution or bacterial culture, is assessed. This method allows for the interrogation of molecular interaction …

In this study, it was found that, the supernatant of sludge suspension in a membrane bioreactor (MBR) for wastewater …
Web13 de out. de 2024 · Effector recognition is mediated by nucleotide-binding, leucine-rich repeat (NLR) proteins encoded in the plant genome, and this recognition initiates defence responses by the plant. This recognition-based resistance can be very effective, but it can also rapidly be overcome if the pathogen evolves to lose or modify the recognised effector. WebIt is also described that HTLV-2 infection appears as a coinfection with HIV-1. We have selected samples corresponding to 583 IDUs infected with HIV and screened for the presence of HTLV-1/2 antibodies. We have performed the molecular characterization of HTLV-2 in three confirmed positive cases on the basis of the long terminal repeat region.
