(2021), Thermal Characteristics of Forced Convection in Combined Pressure and Shear Driven Flow of a Non-Newtonian Third Grade Fluid Through Parallel Plates, Heat Transfer-Wiley, DOI: https://doi.org/10.1002/htj.22201 Abstract: Heat transfer in a non-Newtonian third-grade fluid, flowing under the action of pressure gradient and shear, through two parallel plates, is considered. The upper plate moves with a constant velocity. Constant wall heat fluxes are applied to the plates. Effects of viscous dissipation are also included in the flow field. The governing equations are non-linear and are solved semi-analytically by the Least Square Method (LSM). Further, approximate analytical solutions are obtained by the perturbation method which validates the results generated by the LSM. The effects of the third-grade fluid parameters on the velocity and temperature and Nusselt’s number are discussed.

1. Behera, M., Tiwari, N., Basu, A., Mishra, S. R., Banerjee, S., Chakrabortty, S., & Tripathy, S. K. (2021), Maghemite/ZnO nanocomposites: A highly efficient, reusable and non-noble metal catalyst for reduction of 4-nitrophenol, Advanced Powder Technology, accepted. DOI: 10.1016/j.apt.2021.06.005 (IF: 4.8)
Heterogeneously catalyzed reactions are considered to be the cornerstone for numerous chemical processes and employed extensively for production of a large number of consumer products. However, the proliferating cost of Noble metals and limited resources of catalytically active metals have urged researchers to explore alternative candidates for industrial applications. In the present work, Maghemite/ZnO nanocomposites was processed by a two-step process and utilized successfully as a non-Noble metal catalyst for hydrogenation of p-nitrophenol. As this innovative material could be recycled with no significant decline in its catalytic efficacy, it may find its application in large scale chemical process industries.

(2021), Treatment of arsenic sludge generated from groundwater treatment plant: A review towards a sustainable solution, South African Journal of Chemical Engineering, vol. 37, pp 214–226. https://doi.org/10.1016/j.sajce.2021.06.003. Cite score: 6.2
Arsenic pollution in groundwater that exceeds the permitted limit has been identified as a serious threat that has raised the alarm in a number of developing countries. Though a variety of technologies have been used to remove arsenic from water, little effort has been made to ensure that the generated sludge from arsenic-removing groundwater treatment plants is properly stabilised to prevent leaching. This research examines the possibilities of stabilising arsenic resistant sludge by forming bricks and cement blocks, based on a thorough analysis of known technologies for safe arsenic sludge disposal.
3. Newar, J., Verma, S., Ghatak, A. (2021), Effect of Metals on Underwater Adhesion of Gastropod Adhesive Mucus, ACS Omega, Vol. 6, No. 24, pp. 15580-15589, DOI: 10.1021/acsomega.0c06132 (IF: 3.512).
Many gastropods release adhesive mucus, which help them to remain attached to different substrates. We investigated the role of metals in improving the underwater adhesive property of the mucus from the slug Laevicaulis alte. We found that adhesive function of the mucus could be improved by treatments with salts of metals, namely, Ca, Mg, Cu, or Zn. Treatment with Cu²⁺ and Zn²⁺ increased its strength and underwater stability almost threefold. Our study showed that treatment with Zn²⁺ is the best choice for improvement of the underwater adhesive property. Overall, this work presents a novel biological underwater adhesive with a dynamic behavior in a versatile metal-rich environment.

Glaucoma is a progressive and irreversible eye disorder that ultimately leads to loss of vision. In glaucoma, primary site of injury is the trabecular meshwork, TM, which contains collagen beams and endothelial cells with extracellular matrix (ECM). Mass spectrometry analysis revealed that Autophagy related proteins are predominant over apoptosis in ex-vivo dissected TM specimens from patients with severe adult primary open-angle (POAG) or angle-closure glaucoma (PACG) compared to controls (cadaver donor cornea). We conclude a preference of autophagy over apoptosis may underlie stage transition from moderate to severe glaucoma that is tightly regulated by epigenetic modulators.

Pseudoexfoliation (PXF) is a unique form of glaucoma characterized by accumulation of exfoliative material in the eyes. We performed Multiplex ELISA of tears, aqueous humor (AH) and serum samples and immunohistochemical analysis of tenon’s capsule of patients with PXF stages. We found that TGFβ1, MMP-9 and FN1 protein expression were upregulated in Pseudoexfoliation glaucoma (PXG) compared to PXF. Interestingly gelatin zymography showed that MMP-9 protein activity was downregulated in PXG compared with control or PXF.
We have observed downregulation of differential expression of different growth factors in these samples in correlation of disease progression.

Pani, A., and Singh, S. P. (2021), Reclamation of Sedimented Ash Deposit by Chemical Columns, Journal of Hazardous, Toxic, and Radioactive Waste, ASCE (IF – 1.44) (Accepted)
Abstract: This research focuses on the potentiality of Ca(OH)2 and NaOH columns in augmenting the geoengineering and geo-environmental properties of sedimented ash beds. Model ash beds were stabilized with NaOH and Ca(OH)2 of 9 M concentration. The magnitude of strength development around Ca(OH)2 column is found to be relatively insignificant and limited to column periphery whereas NaOH treatment shows significant improvement. Calcium-based hydration compounds are found in Ca(OH)2 treated ash bed whereas NaOH treatment displays both geo-polymeric/calcium based hydration compounds. Encapsulation of leached-elements in the reaction matrix reduces their concentrations in leachate which was identified to be influenced by pH value.

The energies sector relies heavily on critical infrastructure and cloud usage. Hence, there is a simultaneous increase in the insecurities prevailing in both environments. Smart grids are vulnerable to cyber insecurities due to immense networking and data delivery. In this paper, we propose some of these insecurities that prevail in the cloud computing environment (Trustworthy Space) and the energy sector for smart grids. The insecurities are classified based on the motivation behind them. We rely on the Multi-Criteria Decision Making (MCDM) tool, Analytic Hierarchy Process (AHP) to determine how these insecurities affect smart grids.

(2021), Improving ductal carcinoma in situ classification by convolutional neural network with exponential linear unit and rank-based weighted pooling, Complex and Intelligent System, Vol. 7, pp. 1295–1310, (IF: 3.717).
Ductal carcinoma in situ is a pre-cancerous lesion in the ducts of the breast, and early diagnosis is crucial for optimal therapeutic intervention. Thermography imaging I.s a non-invasive imaging tool that can be utilized for detection of DCIS and although it has high accuracy (~ 88%), it is sensitivity can still be improved. Hence, we aimed to develop an automated artificial intelligence-based system for improved detection of DCIS in thermographs. This study proposed a novel artificial intelligence based system based on convolutional neural network termed CNN-BDER on a multisource dataset containing 240 DCIS images and 240 healthy breast images.

Abstract: In the competitive energy market, ensuring a reliable power supply becomes a major concern and accordingly, the distribution system must be equipped with protective devices to reduce frequency and duration of fault. In addition, large-scale integration of renewable energy sources (RES) is required because of the enormous load growth. In case of any fault, these devices can improve overall reliability by continuing power supply to the isolated loads. Accordingly, this study introduces a bi-level planning model where the optimal integration of RES and DSTATCOM is determined in upper-level planning and the protective devices are incorporated in lower-level planning.

This paper proposes a bidirectional DC–DC converter with soft-switching capabilities. The main characteristic of this converter is that it can be operated in both boost and buck modes. The major advantages of this converter are high efficiency and reduced switching loss in high-power and high-voltage applications. The soft-switching capability is obtained by additional dual auxiliary resonant circuits connected to the conventional non-isolated bidirectional DC–DC converter. Except for the auxiliary switches, all main switches turn on with zero-voltage switching in this proposed bidirectional DC–DC converter. The auxiliary switches turn off with zero current transition.

The data transmission in a multi-hop network, as used for military purposes, follows a many-to-one pattern resulting in a heavier traffic load for nodes near to sink. Hence, thesenodes deplete energy very soon resulting in a vacuum of energy and breakage of the network. This article aims to mitigate the EHP by implementing a corona-based model in a clustered network. Here the CH selection is regularized by preferring the outer corona nodes over the inner ones. The proposed model is implemented in both homogeneous and heterogeneous networks and better network performance is observed.

Reversible circuits have been extensively investigated because of their applications in areas of quantum computing or low-power design. This paper introduces a design for testability (DFT) technique for reversible circuits where the gates of a circuit are clustered into different sets and the gates from each cluster are then connected to an additional input line. Such arrangement makes it possible to achieve 100% fault detection in any reversible circuit with a small increase in quantum cost. Experimental evaluations confirm that the proposed DFT technique incurs less quantum cost overhead with 100% fault detection compared to the existing DFT techniques.

A comprehensive risk assessment framework has been proposed in this article for three types of Synchrophasor Communication Networks (SCNs), The proposed framework uses hardware reliability as well as data reliability to evaluate the associated risk. A simplified hardware reliability model has been proposed for each of these networks, based on failure probability to assess risk associated with hardware failures. Furthermore, the packet delivery ratio (PDR) metric is considered for measuring risk associated with data reliability. To mimic practical shared and hybrid SCNs, the risk associated with data reliability is evaluated for different background traffics. The analytical results are meticulously validated by considering a case study of West Bengal’s (a state in India) power grid.

This paper presents an optimized algorithm for event-triggered control (ETC) of networked control systems (NCS). Initially, the traditional back stepping controller is designed for a generalized nonlinear plant in strict-feedback form that is subsequently extended to the ETC. In the NCS, the controller and the plant communicate with each other using a communication network. In order to minimize the bandwidth required, the number of samples to be sent over the communication channel should be reduced. This can be achieved using the non-uniform sampling of data. However, the implementation of non-uniform sampling without a proper event triggering rule might lead the closed-loop system towards instability. Therefore, an optimized event triggering algorithm has been designed such that the system states are always forced to remain in stable trajectory.

Ray, S., Rout, A.K., Sahoo, A.K.(2021),A comparative analysis of the abrasion wear characteristics of industrial wastes filled glass/polyester composites based on the design of experiment and neural network,Polymer Composites, Vol. 42, No. 1, pp. 424-438, DOI: 10.1002/pc.25836. DOI: 10.1002/pc.25836(I.F: 3.171).
This article presents the abrasion wear behaviour of different industrial wastes filled glass/polyester composites. Two types of fillers such as fly ash and granite dust are chosen with different weight proportions along with polyester and glass fiber for fabricating the composite using hand layup route. Abrasion wear properties of the developed composites are studied in the dry sand abrasion wear test rig as per the ASTM-G-65 standard. The experiments were conducted based on Taguchi design. Between the two fillers, granite filled composite showed better abrasion resistance property as compared with fly ash. The results are predicted using neural network and also compared with the experimental and regression model data. Abraded surfaces are examined by the SEM to ascertain the different wear mechanisms responsible for abrasion loss of material.

The present study was aimed to evaluate the ergonomic risks in the agricultural sectors that may lead to mental stresses as well as musculoskeletal disorders among farmers. This study was carried out by considering 149 farmers from the states of “Chhattisgarh and Odisha” in India. The ergonomic tool such as “Rapid Entire Body Assessment” was used to analyze the working postures of farm workers. Further based on the objective function as minimization of mental stresses on farmers, the “Particle Swarm Optimization and Simulated Annealing” algorithms were used to find the best fitness values. Based on the findings, suitable ergonomic-solutions may be undertaken for the design and development of proper farm-related as well as farmers’ protective tools for their benefits.

Farmers are dependent upon various exceptional work-related stressors, a significant number of which have been exasperated as of late by changes in cultivating practice and by other factors. The present was based on in-depth review of literature and analysis of works based on the mental workloads and stresses of framers. The risks associated with the Indian agricultural sectors were identified. And then SWARA method was used for calculating the weights and corresponding ranking of the criterion/ parameter along with sub-criteria/sub-parameters were done accordingly. Then, the QFD technique was used to suggest the design parameters so as to minimize the work stress on farmers.

Current work utilizes PVDcoated (TiAlN) carbide insert in dry hard turning of AISI D2 steel. The multi-responses like tool-flank wear, chip morphology, and chip reduction coefficient are considered. To achieve the best combination of input cutting terms, grey-fuzzy hybrid optimization (Type I and Type II) is utilized considering the Gaussian membership function. The optimal combination of input terms is found as t-1 (0.15 mm), s-4 (0.25 mm/rev) and is Vc-2 (100 m/min) which is comparable to the results obtained under spray impingement cooling using CVD tool in the literature. Further, six different types of cascade-forward-back propagation neural network modelling is accomplished. Among all models, CFBNN-4 model exhibited the best prediction results with a mean absolute error of 2.278% for flank wear (VBc) and 0.112% for the chip reduction coefficient (CRC).

DOI: 10.1007/s40799-020-00429-x (IF: 1.167).
In this paper 0.8, 1.2, 1.6 and 2 wt.% of submicron-TiB2 particulate reinforced Al 7075 metal matrix composites (MMCs) were fabricated following a modified liquid metallurgy technique, which included ball milling, semi-solid stirring and ultrasonic agitation assisted squeeze casting method. Results revealed excellent incorporation and dispersion uniformity of the reinforcements in the matrix phase. Occasional formation of reaction by-products (Al4C3) was observed at the interface of 1.2 wt.% TiB2 reinforced MMC. Reduction of precipitates and large grain refinements were observed for the MMC containing 1.6 wt.% of TiB2. In the microstructure of Al 7075/2 wt.% TiB2 MMC, superior dispersion of reinforcements at grain boundaries and inter-dendritic regions, along with presence of metastable η-MgZn2 phases was identified. Crystalline phase identification of all the composite samples was also performed through XRD analysis, which validated the elemental phase distribution results of EDS.

Considering performance and emission characteristics calophyllum inophyllum oil methyl ester and pentanol blend (CIME20–P20) depicts a higher brake specific fuel consumption of 3.41% while lower exhaust gas temperature and brake thermal efficiency of 13.46% and 1.18% in contrast to diesel fuel. Carbon dioxide, hydrocarbon, oxides of nitrogen and smoke opacity for CIME20–P20 were 57.02%, 59.37%, 17.39% and 41.53% lower than conventional diesel fuel. CIME20–P20 depicts better performance and diminished exhaust emission thereby making it more potential to substitute the conventional fuel without any engine alteration for better environmental sustainability and energy security.

The objective of the present work is to analyze the consequences of the sonication period on the colloidal stability and thermal conductivity of SiO2–water nanofluid. The obtained results indicate that increasing sonication time is crucial for the enhancement in stability and thermal conductivity of nanofluid. With increasing temperature, the thermal conductivity of nanofluids also increased. Moreover, at lower temperature, sonication plays a dominant role on thermal conductivity enhancement in nanofluids. The investigation concludes that a minimum 2.5 h of sonication is required for the better performance of nanofluids.

Stable suspensions of aqueous Al2O3 and TiO2 nanofluids at two different concentrations of 0.01 and 0.1 wt% were prepared and allowed to flow through a horizontal annulus under varying heat flux from 26,140.132 to 53,573.503 W⋅m‒2 and varying flow rates from 3 to 6 L⋅min‒1. A maximum of 2.4 times enhancement in HTC relative to water was observed. Highest pressure drop of 33.33 % was registered with nanofluids at 0.1 wt%. Figure of merit showed that nanofluids are better alternatives to their basefluids for superior heat transfer.

Stable nanofluids were prepared by dispersing dry SiO2 particles directly in water using sonication. The thermal conductivity of nanofluid with mass concentrations of 0.01 % to 1 % was estimated using a unique ultrasonic velocity measurement technique at various temperatures over 25 °C to 65 °C for every 10 °C rise. Experimental data are analyzed through statistical method and a simple linear regression model (with R2 > 0.99) of thermal conductivity is presented. Further, pricewise performance of nanofluids is performed to obtain the economic feasibility of SiO2–water nanofluids in heat transfer applications.

Blockchain technology has gained increasing attention as it ensures transparency, trust, privacy, and security. However, the critical factors affecting efficiency require further study. Here, we define the critical factors that affect blockchain implementation in the healthcare industry. We extracted such factors from the literature and from experts, then used interpretive structural modeling to define the interrelationships among these factors and classify them according to driving and dependence forces. This identified key drivers of the desired objectives. Regulatory clarity and governance (F2), immature technology (F3), high investment cost (F6), blockchain developers (F9), and trust among stakeholders (F12) are key factors to consider when seeking to implement blockchain technology in healthcare. Our analysis will allow managers to understand the requirements for successful implementation.
