With the security requirements of networks, biometrics authenticated schemes which are applied in the multi-server environment come to be more crucial and widely deployed. In this paper, we propose a novel biometric-based multi-server authentication and key agreement scheme which is based on the cryptanalysis of Mishra et al.'s scheme. The informal and(More)
To identify genes essential to biofilm formation in Pseudomonas putida KT2440, 12 mutants defective in oxidative stress-related or metabolic pathway-related genes were evaluated. Of them, only the dsbA mutant lacking the disulfide bond isomerase exhibited significantly increased attachment to the polystyrene surface. Visual evaluation by extracellular(More)
The ability of ferrate (Fe(VI)) to oxidize phenolic endocrine-disrupting chemicals (EDCs) and phenols during water treatment was examined by determining the apparent second-order rate constants (k(app0) for the reaction of Fe(VI) with selected environmentally relevant phenolic EDCs (17alpha-ethinylestradiol, beta-estradiol, and bisphenol A) and 10(More)
Various oxidants such as chlorine, chlorine dioxide, ferrate(VI), ozone, and hydroxyl radicals can be applied for eliminating organic micropollutant by oxidative transformation during water treatment in systems such as drinking water, wastewater, and water reuse. Over the last decades, many second-order rate constants (k) have been determined for the(More)

Similarly, a diverse collection of smartphone(More)
Fenton chemistry, which is known to play an effective role in degrading toxic chemicals, is difficult to apply to disinfection in water treatment, since its reaction is effective only at the acidic pH of 3. The presence of oxalate ions and UV-visible light, which is known as a photoferrioxalate system, allows the Fe(III) to be dissolved at slightly acidic(More)
In Escherichia coli, the SoxR regulon orchestrates genes for defense against certain types of oxidative stress through the SoxR-regulated synthesis of the SoxS transcription activator. The Pseudomonas putida genome did not reveal a clear soxS homolog. The P. putida SoxR protein appears to be functional: its expression in an E. coli DeltasoxR strain restored(More)
The ferredoxin-NADP+ reductase (fpr) participates in cellular defense against oxidative damage. The fpr expression in Pseudomonas putida KT2440 is induced by oxidative and osmotic stresses. FinR, a LysR-type transcriptional factor near the fpr gene in the P. putida KT2440 genome, is required for induction of the fpr under both conditions. We have shown that(More)
