Characterising four Sarconesiopsis magellanica (Diptera: Calliphoridae) larval fat body-derived antimicrobial peptides

Mem. Inst. Oswaldo Cruz; 116 (), 2021
BACKGROUND The inappropriate use of antibiotics has led to the accelerated growth of resistance to antibiotics. The search for new therapeutic strategies (i.e., antimicrobial peptides-AMPs) has thus become a pressing need. OBJECTIVE Characterising and evaluating Sarconesiopsis magellanica larval fat b...

Real Power Loss Reduction by Melon Fly Optimization and Spontaneous Process Algorithm's

Abstract In this work Melon Fly Optimization (MFO) Algorithm and Spontaneous Process Algorithm (SPA) is designed to reduce the Real power loss, voltage stability enhancement and reducing the Voltage deviation. In this work real power loss measured and how much loss has been reduced is also identified by ...
