Tetra acetyl ethylene diamine (TAED) was used as an activator in H2O2 bleaching to improve bleaching efficiency. The present work was aimed at confirming different activations for various H2O2/TAED bleaching processes, including the addition of acetic anhydride and the stepaddition of sodium hydroxide. The results showed that an acetic anhydride dosage of 1%, an acetic anhydride treatment time ...

BACKGROUND This study addresses the efficacy of an automated decontamination protocol using the germicide 'tetra acetyl ethylene diamine (TAED) perborate' (Farmec SpA, Italy). The germicide TAED perborate protocol is used in the Castellini Dental Units fitted with an Autosteril unit (an automated device that can cycle 0.26% TAED perborate solution and sterile water for cleaning the water system...

Error correction codes are used in semiconductor memories to protect information against soft and hard errors. Soft error is a major concern for memory reliability especially for memories that are used in space applications. Hamming codes are attractive as they are simple to construct for any word length and encoding / decoding can be done with low latency. In this paper, the design of Single E...

Received Nov 21, 2017 Revised Jan 26, 2018 Accepted Feb 12, 2018 In the OFDM communication system channel encoder and decoder is the part of the architecture. OFDM channel is mostly affected by Additive White Gaussian Noise (AWGN) in which bit flipping of original information leads to fault transmission in the channel. To overcome this problem by using hamming code for error detection and corre...

This work investigated the efficiency of a tetraacetylethylenediamine/ hydrogen peroxide/triethanolamine (TAED/H2O2/TEA) system for lowtemperature bleaching of cotton fabric, with and without ultrasonic assistance. The low-temperature bleaching results were compared to those obtained from a conventional H2O2 bleaching system. The application of TAED/H2O2/TEA without ultrasonic assistance to gre...

The high level of security and the fast hardware and software implementation of the Advanced Standard Encryption (AES) have made it in the first choice for many critical applications. Advanced Encryption Standard (AES) is the self-determining hardware architecture for producing crypto mechanism. In a secure transmission system, Content Addressable Memory (CAM) based transmissions always provide...

From 138,662 embryophyte (higher plant) and 348,142 chordate genes, 4216 embryophyte and 15,452 chordate gene families were generated. For each of these gene families, multiple sequence alignments, phylogenetic trees, ratios of non-synonymous to synonymous nucleotide substitution rates (K(a)/K(s)), mappings from gene trees to the NCBI taxonomy and structural links to solved three-dimensional pr...

background. this study evaluated the antimicrobial activity of tetraacetylethylenediamine-sodium perborate (taed-sp) in comparison to 2.5% and 5% sodium hypochlorite (naocl) against enterococcus faecalis. methods. a standard suspension of e. faecalis was inoculated on 60 plates containing mueller-hinton agar culture medium. four sterile disks of beckman filtration paper were placed on each plat...
