Graphene-based 3 nef runes devices have important applications attributed to their superior performance and flexible tunability in practice.In this paper, a new kind of absorber with monolayer graphene sandwiched between two layers of dielectric rings is proposed.Two peaks with almost complete absorption are realized.The mechanism is that the doubl
Abstract Microbes live within complex communities of interacting populations, either free-living in waters and soils or symbionts of animals and plants.Their interactions include the production of antimicrobial peptides (bacteriocins) to antagonize competitors, and these producers must carry their own immunity gene for self-protection.Whether other
This study was carried out to investigate effects of microelements under water deficit stress at different growth stages on antioxidant enzyme alteration, chemical biomarker and grain yield of maize in the years 2007 and 2008.The experiment was conducted in a split plot factorial based on a randomized complete block design with four replications.Th
This paper suggests an enhanced control scheme for a four-leg battery energy storage systems (BESS) under unbalanced and nonlinear load conditions operating in the isolated microgrid.Simplicity, tiny steady-state error, fast transient response, and low total harmonic distortion (THD) are the main advantages of the method.Firstly, a new delta zeta j
