Secure access control for manufacturing sector with application of ethereum blockchain

Abstract: Past local and worldwide international logistic operations have been related with obscure data streams that have thwarted detectability and made obstacles in deregulation. Ethereum based Distributed Ledger Technology and unified advancements were explored for solving the issues looked of Cloud-Based Manufacturers. Nonetheless, past writing has zeroed in on restricted parts of a regular Cloud-Based Manufacturing chain, for example, checking resources and making sure about discernibility, which is generally dismissing information trustworthiness and information access. To conquer such disadvantages, the current study attempts to protected keen agreements dependent on ERC20 interface of controlled Ethereum based Distributed Ledger Technology with significant cycles and capacities to get an all encompassing structure for making sure about Cloud-Based Manufacturing activities. The adequacy was exhibited on the study. So, it was discovered that basic escape clauses in blockchain can be beaten utilizing the prototyped structure. Also, a few blueprints for future examination are plot.

Removal of toxic hexavalent chromium from aqueous solution by nickel ferrite-polyaniline nanocomposite

Abstract: Cr(III) and Cr(VI) are toxic metal ions and available in trace amounts in aquatic system. These ions can easily enter into the human body and particularly Cr(VI) can cause serious health problems. As per government regulations, it is necessary that all the industries, before discharging the effluents containing chromium, should reduce the level below the allowable limit. A number of methods have been developed to remove chromium ions particularly Cr(VI) from aqueous solutions. In this paper, we prepared NiFe2O4–PANi nanocomposite and used it for the removal of Cr(VI) from the aqueous solution of K2Cr2O7. The process of adsorption was studied by varying pH of the solution, adsorbent dose, metal ion concentration, and contact time. The adsorption studies were also made using PANi alone as an adsorbent. The results showed that the nanocomposite gave good results. The removal of Cr(VI) was maximum at pH ~2.0. The adsorption isotherm was verified on the basis of Langmuir, Freundlich, Temkin, and Dubini...

Functional Diversity of Quorum Sensing Receptors in Pathogenic Bacteria: Interspecies, Intraspecies and Interkingdom Level.

Abstract: The formation of biofilm by pathogenic bacteria is considered as one of the most powerful mechanisms/modes of resistance against the action of several antibiotics. Biofilm is formed as a structural adherent over the surfaces of host, food and equipments etc. and is further functionally coordinated by certain chemicals produced itself. These chemicals are known as quorum sensing (QS) signaling molecules and are involved in the cross talk at interspecies, intraspecies and interkingdom levels thus resulting in the production of virulence factors leading to pathogenesis. Bacteria possess receptors to sense these chemicals, which interact with the incoming QS molecules. It is followed by the secretion of virulence molecules, regulation of bioluminescence, biofilm formation, antibiotic resistance development and motility behavioral responses. In the natural environment, different bacterial species (Gram-positive and Gram-negative) produce QS signaling molecules that are structurally and functionally different. Recent and past research shows that various antagonistic molecules (naturally and chemically synthesized) are characterized to inhibit the formation of biofilm and attenuation of bacterial virulence by blocking the QS receptors. This review article describes about the diverse QS receptors at their structural, functional and production levels. Thus, by blocking these receptors with inhibitory molecules can be a potential therapeutic approach to control pathogenesis. Furthermore, these receptors can also be used as a structural platform to screen the most potent inhibitors with the help of bioinformatics approaches.

Design and Optimization of Microstrip Patch Antenna for UWB Applications Using Moth–Flame Optimization Algorithm

Abstract: The design of microstrip patch (MP) antenna using Moth–Flame optimization (MFO) algorithm for UWB applications is presented in this article. MP antennas are designed to operate in dual and multi-band application as it possess the following advantages such as low cost, light weight and easy installation. To reduce the microstrip patch cross-polarized radiation and to attain the essential radiation parameters, the MP antenna is designed with a defected ground structure. The substrate of liquid crystal polymer is used here to reduce the material cost and the applicable geometry parameters are used to improve antenna performance. The MFO optimized antenna represents 50 mm × 50 mm compact size, which improves the performance of antenna. However, the simulation procedure is done by the MATLAB tool along with high frequency structure simulator for parameter optimization and performance analysis respectively. The operational bandwidth of the antenna is 3.1 GHz and the return loss is − 20 dB that covers the UWB (3.1–10.6 GHz) applications. The simulation outcomes exhibit good impedance bandwidth, radiation pattern, directivity, and relatively constant gain over the entire band of frequency comparing with the earlier methods. Finally, the proposed system can be a better option for the design of microstrip antenna in the communication system, to cover Bluetooth operations, Wi-Fi, Wi-MAX, Telemedicine and UWB applications.
