Media Ethics in Times of Demonetization: Framing Debates in English News Channels
Objectivity has been a traditional ideal for journalism. Journalists are trained to be objective; they do not frame stories by themselves????or do they? Faced with the pressure of deadlines, strained resources and the perception that audience prefer reportorial style, journalists resort to amusement or conflict based reporting positioning one side against the other and often aggravating facts and issues. The public today expresses disappointment with current media practices. Media watchers argue that instead of improving the quality of programming, competition has resulted in a race to the bottom, where news channels have conveniently forgotten basic ethical norms. This study is an attempt at re-visioning media ethics. It is believed that ethical journalism is never more important than in the time of crises. Taking India???s recent economic crisis, demonetization, this research aims to answer what makes it difficult for journalists to adhere to ethics especially during crises? With emphasis on situation faced by reporters, pressure imposed on them by various sources and ethical dilemma, this study provides answers to the questions posed on the work of journalists. Content analysis of demonetization debates broadcasted on two popular English news channels and interview responses of experienced journalists of Indian news media goes to explain how demonetization was represented by Indian news channels and to what extent journalistic ethics was reflected in their content. -

Optimization of Abrasive Wear Parameters of Halloysite Nanotubes Reinforced Silk/Basalt Hybrid Epoxy Composites using Taguchi Approach
The demand for environmentally friendly and sustainable materials for nonstructural and structural applications grows by the day. Polymeric composites reinforced with fillers and fibres are considered to have increased strength and desirable wear resistance. Abrasive wear of industrial and agricultural based components are currently one of the most serious issue. Therefore, the current research reports on the influence of Halloysite-Nanotubes (HNTs) loading on the three body abrasive behavior of bi-directional silk fibre (SF) and basalt fibre (BF) reinforced epoxy (Ep) composites. Rubber wheel with dry sand abrasion testing in accordance with ASTM G65-16e1 was performed with four control parameters such as filler content, load, abrading distance and silica sand size. The tests were planned as per orthogonal array of Taguchi (L27). Significant impact of control factors were identified using ANOVA (Analysis of variance). The results demonstrated that adding HNTs to SF-BF/Ep nanocomposites significantly improved the wear resistance and the combination of A2, B1, C3 and D1 control factors yields the lower specific wear rate (SWR). Findings exhibit that the load and abrading distance were the most significant parameters affecting the abrasive wear of SF-BF/Ep nanocomposites followed by filler content and silica sand size. Microstructural features were observed via scanning-electron-microscopy (SEM). 2022 Published by Faculty of Engineering. -
Mechanical and Wear Behavior of Halloysite Nanotubes Filled Silk/Basalt Hybrid Composites Using Response Surface Methodology
The aim of this study is to develop bio-friendly light weight polymer nanocomposites for load bearing applications and to evaluate the influence of halloysite nanotubes (HNTs) on mechanical as well as wear behavior of silk fiber (SF) and basalt fiber (BF) reinforced epoxy (Ep) composites. HNT filled biocomposites were fabricated using vacuum bagging technique. The Box-Behnken design (BBD) of experiment with Response surface methodology (RSM) was used to conduct the dry-sliding wear tests on a pin on disc apparatus. Tribo-mechanical properties and worn surface micrographs of hybrid composite samples were analyzed. Hardness, tensile strength and wear resistance behavior of SF + BF/Ep hybrid composites were substantially improved with the incorporation of HNTs. It was observed from the confirmation test that there is a strong agreement between the experimental findings as well as the predicted values, with a minimum reported error of <5% for HNT-SF + BF/Ep hybrid nanocomposites. SEM micrographs of the worn-out surface of HNT filled SF + BF/Ep composite exhibited fiber breakage, pulverized matrix, good interfacial bonding and fractured fibers. The novelty of the current research work is the development of eco-friendly polymeric composites for wear resistant and structural applications. The effect of hybridization (fiberssilk and basalt, fillersHNTs) on the tribo-mechanical properties of polymeric composites were investigated for the first time. The study showed that the mechanical as well as the tribological properties of SF and BF reinforced epoxy composites were enhanced with the addition of nanofiller.

Effect of basalt fiber hybridization on mechanical properties of silk fiber reinforced epoxy composites
Poor mechanical properties and constraints on production presently limit the utilization of bio-based reinforcing agents to non-structural and structural automotive elements. The conjugation of natural fibre with volcanic rock fibre provides a way to improve the mechanical properties of composites over natural fibre alone. In this study, physico-mechanical properties of hybrid fibre (silk and basalt) reinforced epoxy composites were found by experimentation following acceptable ASTM standards. Hybrid composites were produced by combining silk/basalt fibres in the ratio of 50:0, 25:25 and 30:20, whereas overall weight fraction was maintained at 0.5. The experimental results showed that the performance of combined fibres were superior compared to that of silk fibre bolstered epoxy composites. Among the 2 varieties of hybrids, the silk/basalt (25:25 by weight ratio) combination offered the very best hardness, strength, modulus, and toughness to the epoxy matrix owing to the similar modulus and synergistic interaction between the two reinforcing fibres. The results also steered that the morphology and surface adhesion affected the strength of the hybrid composites. These observations give insight into the advantages of various fibre reinforcements to the mechanical performance of epoxy matrix which is considered to be brittle. The failure mechanisms and the adhesion between fibres and matrix were studied by analysing the photomicrographs of broken coupons. 2020 Elsevier Ltd. -
Effect of Halloysite Nanotubes on Physico-Mechanical Properties of Silk/Basalt Fabric Reinforced Epoxy Composites
Natural fiber reinforced polymer composites have become more attractive due to their high specific strength, light weight and environmental concern. However, some limitations such as low modulus and poor moisture resistance were reported. This paper presents the role of halloysite nanotubes (HNTs) on physico-mechanical properties of bidirectional silk and basalt fiber reinforced epoxy (SF-BF/Ep) hybrid composites. Vacuum bagging and ultra-sonication method were used for the fabrication of hybrid composite slabs. The effect of HNT loadings (1.5, 3 and 4.5 wt. %) on physico-mechanical characteristics like density, hardness, flexural and impact properties of SF-BF/Ep composites were determined according to ASTM standards. Experimental results revealed that the incorporation of HNTs improves the mechanical properties. The impact strength of SF-BF/Ep is predominant at 3 wt. % HNT loading where the impact strength surges to 568.67 J/m, which may render HNT filled SF-BF/Ep desirable for various toughness-critical structural applications. The test results demonstrated that SF-BF/Ep-3HNT coded composites exhibited improved mechanical properties among the all composites. 2022 Trans Tech Publications Ltd, Switzerland. -
Role of Silk Fiber Loading on Physico-Mechanical Properties of Epoxy Composites
Researchers have suggested the usage of lightweight materials in the automotive and other engineering components which has proven to be one of the potential ways to meet demand for fuel efficiency and eliminate greenhouse gas emissions generated by the manufacturing industries. In this study, silk fiber (Bombyx-mori) reinforced epoxy biocomposites were fabricated by hand layup method with different loadings of fiber and their physico-mechanical properties were studied following acceptable ASTM standards. The properties of the epoxy matrix were significantly enhanced with the silk fiber loading, displaying optimum properties at 50wt. % silk fiber loading. The findings also led that morphology of silk fiber and surface adhesion with the epoxy matrix affects the properties of biocomposites. Such findings provide perspective into the benefits of fiber reinforcements to the physio-mechanical performance of the epoxy resin. The mechanism of failure and consequently the adhesion between fibers and matrix were analyzed by observing the photomicrographs of the damaged coupons. 2021 Taylor & Francis. -

Machine Learning and Word Representation Techniques in Medical Transcription Data Analysis
Dermatology is the branch of medicine that deals with the diagnosis, treatment, and prevention of skin diseases. Dermatological diseases can be difficult to diagnose, treat, and manage because there are several skin conditions, each with its unique set of symptoms and causes. Underlying medical conditions, environmental causes, or hereditary characteristics can cause complex skin problems. Furthermore, because skin problems can present in a variety of ways, obtaining an appropriate diagnosis and efficient treatment may be difficult. Treating dermatological disorders is a difficult endeavor. This article proposes an integrated model to assist people in understanding and discussing the nature of dermatology. This model's capabilities include text pre-processing, audio-to-text translation, named entity recognition (NER) for extracting crucial information, and text clustering and classification based on content. The necessity for precise and efficient analysis of large amounts of text data, notably the identification and standardisation of abbreviations and the extraction of relevant information, has been identified as a problem in dermatology and medical transcription. By grouping similar cases, clustering can make it easier to spot patterns and trends in dermatological disorders. However, classification can help automatically group text data into pre-established categories, such as various kinds of skin conditions or treatments. These methods simplify data analysis, increase accuracy, and assist healthcare professionals in reaching accurate conclusions regarding patient care. This article explores the partitioning algorithm for clustering, while logistic regression is used in classification. The model analysed in this article helps dermatologists and patients understand and manage skin problems. 2025 IEEE. -

Effect of salt fingers on heat transfer for different non-uniform concentration profiles in a micropolar liquid
This paper discusses the theoretical aspects of the effect of salt fingers on heat transfer for different non-uniform concentration profiles in a micropolar liquid layer kept between two parallel plates of infinite extent separated by a thin layer, heated and soluted from above. The onset of salt finger convection (convection due to the salt finger process) is studied through the linear stability analysis theory. The system of partial differential equations is solved numerically using the normal mode analysis method and the required solution is found by applying the Galerkin method. The effect of heat transfer and concentration of micropolar liquid is obtained for (i) freefree, (ii) rigidrigid, and (iii) rigidfree isothermal, permeable with no-spin boundary conditions. The effect of different micropolar parameters (i.e.,coupling parameter, micropolar heat conduction parameter, couple stress parameter, and inertia parameter) has been analyzed on the onset of stationary convection, and the results are depicted graphically. It is shown that different non-uniform concentration gradients, diffusivity ratio, coupling parameter, and solutal Rayleigh number influence the heat transfer in the system. The phase of concentration flow for different boundary conditions is compared and analyzed. 2022 Wiley Periodicals LLC. -
Evaluating the effect of different ligands on the supercapacitance and hydrogen evolution reaction studies of Zn-Co MOF
Metal-Organic Frameworks (MOFs) have recently attracted a lot of interest because of their potential uses in energy storage and catalysis. In this study, we investigate the impact of various ligands on the electrochemical performance of Zn-Co MOFs for both energy storage and hydrogen evolution reaction (HER) studies. Specifically, Zn-Co MOFs are synthesized using different ligands, and their structural and electrochemical properties are characterized by a range of analytical techniques. 2,5-dihydroxybenzoic acid (DBA) and benzene-1,2,4,5-tetracarboxylic acid (BTC) are employed due to their distinct structural features and potential effects on MOF performance. Subsequently, electrochemical studies are conducted to assess the supercapattery performance and HER activity of these MOFs. The specific capacitance and overpotential value at 10 mA/cm2 of Zn-Co/DBA MOF is observed to be 1775.3 F/g and 186 mV, whereas that of Zn-Co/BTC MOF is found to be 136.6 F/g and 279 mV. The MOF synthesis using DBA as a ligand is more effective for energy-related applications. This study aims to report a multifunctional MOF composite for energy and environmental applications with better efficiency than other reported systems. Our findings provide insights into how the choice of ligand influences the structural properties and electrochemical behavior of Zn-Co MOFs, shedding light on the potential of these MOFs as versatile materials for energy storage and HER applications. 2024 Elsevier B.V. -
An In-Depth Analysis of Collision Avoidance Path Planning Algorithms in Autonomous Vehicles
Path planning is a way to define the motion of an autonomous surface vehicle (ASV) in any existing obstacle environment to enable the vehicle's movement by setting directions to avoid that can react to the obstacles in the vehicle's path. A good, planned path perceives the environment to the extent of uncertainty and tries to build or adapt its change in the path of motion. Efficient path planning algorithms are needed to alleviate deficiencies, that are to be modified using the deterministic path that leads the ASV to reach a goal or a desired location while finding optimal solution has become a challenge in the field of optimization along with a collision-free path, making path planning a critical thinker. The traditional algorithms have a lot of training and computation, making it difficult in a realistic environment. This review paper explores the different techniques available in path planning and collision avoidance of ASV in a dynamic environment. The objective of good path planning and collision avoidance for a dynamic environment is compared effectively with the existing obstacles movement of different vehicles. Different path planning technical approaches are compared with their performance and collision avoidance for unmanned vehicles in marine environments by early researchers. This paper gives us a clear idea for developing an effective path planning technique to overcome marine accidents in the dynamic ocean environment while choosing the shortest, obstacle-free path for Autonomous Surface Vehicles that can reduce risk and enhance the safety of unmanned vehicle movement in a harsh ocean environment. 2024 Bentham Science Publishers.
