Rotor Dynamics of TurbineGenerator Shaft with Dampers During Subsynchronous Resonance Generated by Series Capacitors
Purpose In this paper, an electromechanical approach to study the turbinegenerator shaft stability with and without dampers is made. The shaft is subjected to electrical disturbances created by series capacitors. The high power capacitors help the electric power system to improve the reactive power in high voltage transmission lines. Methods Finite element method is used to study the stability of the shaft under subsynchronous resonance when compared to the traditional methods like eigenvalue analysis, frequency scanning method and digital time simulation techniques. At the same time, it leads to subsynchronous resonance. Results Electromechanical stress in the rotating shaft arises when the resonance is created in the system. Maximum stress and strain of the shaft are calculated with other necessary parameters to prove the system instability. In order to maintain stability, dampers are installed at an optimum location. Conclusion Best location of installing damper is found using ANSYS 16.0 by modal analysis, harmonic and phase response analysis. The damper installed at the point reduces the stress caused by subsynchronous resonance and maintains the stability of the system. 2021, Springer Nature Singapore Pte Ltd. -
Rough Set Based Ant-Lion Optimizer for Feature Selection
As the area of computational intelligence evolves, the dimensionality of any sort of data gets expanded. To solve this issue, Rough Set Theory (RST) has been successfully used for finding reducts as it requires only supplied data and no additional information. This paper investigates a novel search strategy for minimal attribute reduction based on rough sets and Ant Lion Optimization (ALO). ALO is a nature-inspired algorithm that mimics the hunting mechanism of ant lions, and this is inspired to find the minimum reducts. Datasets from the UCI repository are used in this paper. The experimental results show that the features selected by the proposed method are well classified with reasonable accuracy. 2020 IEEE. -
Routing Protocol for Low Power and Lossy Network Using Energy Efficient Priority Based Routing
Internet of Thing (IoT) collects huge amount of data from the surrounding by monitoring and sensing. Further, transferring these data from IoT devices to cloud environment seems is very challenging. Such that, this paper concentrates on energy consumption, in which the energy efficient routing and priority dependent techniques are proposed. This technique depends upon the RPL network (Routing Protocol for Low power and Lossy), which efficiently predicts routing over contents. Every network slot utilizes timing pattern while forwarding image data, audio data. The proposed method enhances the strength of routing protocol and also avoids congestion. The outcomes of the study illustrates that proposed Energy efficient priority based routing (EEPR) technique minimize overheads on mesh, energy consumption and end-end delay. Also, the proposed method outperforms the existing QRPL methods in IoT platform. 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -
Routing TQM through HR strategies to achieve organizational effectiveness: themediating role of HR outcomes in India
Purpose: The present research focuses on improving the awareness related to soft total quality management (TQM) practices by looking from the viewpoint of strategic human resources (HR). In addition, it is intended to reflect on the resulting soft TQM-HR outcomes and determine the mediating effect between soft TQM-HR strategies and organizational effectiveness (OE). Design/methodology/approach: An exploratory research methodology with an online survey technique was adopted for the study. Three hundred and three managerial-level personnel from nine large Indian manufacturing organizations participated in the research. A theoretical model is projected and verified using correlation and mediation analysis. Findings: The results show that commitment, reduced turnover intentions and satisfaction levels of employees mediate the relationship between resources, development and retention strategies and OE. However, the retention strategy has the strongest association with the OE of the three strategies. Also, of the three HR outcomes, satisfaction was strongly associated with OE. The analysis proved that the proposed model is an acceptable fit. Practical implications: Implementing HR-related TQM strategies will likely impact OE since it elicits positive HR outcomes such as commitment, reduced turnover intention and satisfaction. Recognizing human resources as a unique strategic asset will help HR managers devise adequate resourcing, development and retention strategies instrumental in executing TQM. Originality/value: The present micro study is unique in scrutinizing the influence of soft TQM-HR practices on organizational effectiveness by analysing the mediating effects of commitment, reduced turnover intention and satisfaction in Indian large-scale manufacturing organizations. The study is unique since no literature deciphers the linkages between HR strategies and organizational effectiveness in the Indian manufacturing sector. 2023, Emerald Publishing Limited. -

Roxburgh was right: Aponogeton microphyllus and Aponogeton undulatus are distinct species
Aponogeton microphyllus, previously placed under the synonymy of A. undulatus, is recognized here as a distinct species based on morphology, chromosome number, and molecular phylogenetics (nuclear ribosomal internal transcribed (ITS) spacer region). Observations on the type and live specimens revealed morphological differences between the two species. Aponogeton microphyllus flowered regularly and set seeds. Aponogeton undulatus flowered rarely, did not set seeds, but showed formation of young plantlets on the inflorescence axis. Similarly, different chromosome numbers were recorded in Aponogeton microphyllus and the two forms of A. undulatus, viz., AF1 and AF2, whichoccurin distinct populations. Aponogeton microphyllus exhibited polysomaty with root-tip cells showing 2n=40, 42, and 44 chromosomes. The two forms of A. undulatus, AF1 and AF2, showed 2n=84 and 86 chromosomes, respectively. Based on the ITS data, both speciesoccupiedtwo separate clades. Plastid trnK intron region indicated a close relationship between both species. Our study suggests the need for comprehensive phylogenetic analyses of A. undulatus across its distribution range based on more advanced techniques such as high-throughput sequencing data to understand the A. undulatus species complex and to detect natural hybrids of this species. 2023, Indian Academy of Sciences. -
RP-HPLC METHOD FOR QUANTITATIVE ESTIMATION OF NAFTIFINE HYDROCHLORIDE IN FORMULATED PRODUCTS: DEVELOPMENT AND VALIDATION
Background: Naftifine hydrochloride is an allylamine antifungal agent commonly used to treat dermatophyte infections. It inhibits squalene epoxidase, a key enzyme in ergosterol biosynthesis, thereby disrupting the integrity of the fungal cell membrane. It exhibits broad-spectrum activity against dermatophytes, yeasts, and molds, and is typically formulated as a 1% topical cream or gel. Methodology: A rapid and robust reverse-phase high-performance liquid chromatography (RP-HPLC) method was developed and validated for the estimation of naftifine hydrochloride in a topical cream formulation (2% Naftifast, Zydus), in accordance with ICH and FDA guidelines. Chromatographic separation was achieved on an Inertsil ODS column using an isocratic mobile phase consisting of 35% acetonitrile, 40% methanol, 25% water, and 0.8% triethylamine (pH adjusted to 5.5 with acetic acid) at a flow rate of 1.4 mL/min. Detection was performed at 265 nm. Results and Discussion: Naftifine hydrochloride showed a retention time of approximately 4.0 minutes with a total run time of 6.0 minutes. The method displayed excellent linearity over a concentration range of 20120 g/mL (R > 0.999). Recovery studies indicated a mean recovery of 100.4%. Precision was confirmed by relative standard deviation (RSD) values of less than 2%, demonstrating the methods reproducibility. Conclusion: The proposed RP-HPLC method is simple, precise, and time-efficient. It is suitable for routine quality control of naftifine hydrochloride in pharmaceutical dosage forms due to its short analysis time and strong validation performance. 2025 The authors. -
RPA Revolution in the Healthcare Industry During COVID-19
Over the last year, the evolution in Robotic Process Automation (RPA) has been staggering. The automation it brings to applications has yielded efficiency, reduced operating costs, and decreased the time of research, development, and production. Industries have already integrated RPA into their workflow and are profoundly transforming into an intelligent automated industry with minimum human intervention, calling this the fourth industrial revolution. In this race of transformation, the healthcare industry is quite ahead of many other industries. It stood the test of time when COVID-19 was spreading rapidly and was also resilient against all odds. The system did experience an unprecedented crisis that depicted its weakness, fragility, and unpreparedness. The healthcare system was forced to adapt to a new paradigm. And though there was the loss of life and economy, we learned to evolve as a community to tackle this crisis. This chapter sheds light on the role of RPA and covers how these technologies can assist healthcare workers in their day-to-today activities, reviewing what the fourth industrial revolution would look like in the healthcare sector. The intelligent, automated system would provide a seamless experience of gathering information by various means, processing, and assisting healthcare workers to deliver quality treatment. 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. -
Rubitics: The Smarter GCMS for Mars
A GCMS stands for a Gas Chromatograph and Mass Spectrometer. These two instruments are used to identify compounds from both soil and atmospheric samples. The GCMS usually has a mass of around 40 kilograms and is the size of a microwave oven, but what if we could downsize it? Downsizing the GCMS means that the number of equipment and instruments that can be used and carried by a rover can drastically increase. Rubitics is essentially a GCMS, only smaller and more efficient. This paper discusses the way Rubitics functions and how a GCMS can be remodeled and used to its fullest potential. The column of the Gas Chromatograph is replaced with composite materials to increase the flexibility of the tube, thereby increasing the number of columns along with finger-like projections on the interiors, which will aid in a much more precise separation of compounds. The inert carrier gas container is changed with a more durable, strong composite that will be instrumental in reducing the mass of the cylinder, and a safer chemically unreactive material will ensure complete pure storage. Rubitics will also contain a cooling system so as to be more power-efficient and aid in obtaining precise results. The material of the oven used in the gas chromatograph will be of much more insulating capacity (thermal resistance), lighter in mass, and smaller in size. Rubitics maintains the optimum shape to provide the most temperature and energy-efficient GCMS ever. Rubitics houses a compact electronic bay with sensors and a microprocessor for analysing the different components. The detectors' values are processed in the onboard microprocessor with the help of TinyML. This light algorithm can help in reducing the bandwidth consumed in transmitting unnecessary data to the ground station through providing in-situ data filtration. The paper also contemplates using such an algorithm to improve the efficiency of GCMS. In conclusion, Rubitics will be the future of GCMS technologies and sample analysis on different planetary terrains. Due to its re-engineered structure, it occupies lesser weight, size, and space. Rubitics thereby changes the number and quality of experiments that can be performed on Mars, leading to better insights for successful future habitation. Copyright 2022 by Ms. Harshini K Balaji.

Rumination, existential anxiety and professional quality of life among palliative care professionals in India
Objective: Palliative care enhances the quality of life for individuals with life-limiting illnesses, but frequent exposure to death and suffering poses emotional challenges for professionals. This study examines ruminations role in the relationship between existential anxiety (EA) and professional quality of life (ProQOL) among palliative care professionals in India. Methods: A mixed-method research design was employed. Quantitative data were collected from 500 palliative care professionals using the Event-Related Rumination Inventory, EA Questionnaire and ProQOL scale. In-depth interviews were conducted with 27 professionals with high rumination scores. Correlation and regression analyses were used for quantitative data, while thematic analysis was applied to qualitative data. Results: Persistent rumination heightened mortality awareness, exacerbated EA and negatively impacted ProQOL. Rumination partially mediated the relationship between EA and ProQOL. Four key themes emerged: (1) brooding rumination, (2) reflective rumination, (3) impact of rumination on ProQOL and (4) impact of rumination on EA. Individual differences in ruminations intensity and duration were notable. Conclusions: Findings highlight cultural and contextual challenges faced by Indian palliative care professionals, underscoring the need for targeted mental health interventions. This study supports Sustainable Development Goals 3, 8 and 4 by advocating for healthcare worker well-being, job satisfaction and improved mental health training.

Ruralurban financial inclusion: Implications on the cost sustainability of microfinance lenders
Despite the higher demand for credit among the rural poor, many commercial banks and microfinance institutions (MFIs) are averse towards microfinancing activities in rural areas due to their high-cost implication compared to urban areas. Therefore, this study empirically investigates the effect of rural and urban financial inclusion on the cost sustainability of MFIs. To this end, a globally representative sample of 1729 MFIs' data covering the period 20082018 were analyzed. Contrary to the orthodox perception, our overall result revealed that lending in rural areas is more cost-efficient than in urban areas, even after considering various proxies and endogeneity issues. 2021 John Wiley & Sons, Ltd. -
Ruthenium phosphate-embedded poly-(3,4 diaminobenzoic acid)-based electrode for enhanced sensing of 2,4-dichlorophenol in water samples
2,4-Dichlorophenol (2,4-DCP) is found to have a prevalent application in synthesizing many industrial materials, meanwhile leading to toxicological effects on human health and aquatic life. This work demonstrates the construction of a highly responsive electrochemical sensing platform for 2,4-DCP, based on ruthenium phosphate electrodeposited over poly-(3,4 diaminobenzoic acid)-loaded carbon fiber paper (Ru-Pi/PDABA/CFP). Surface modification of the conducting polymer with Ru-Pi improves electrocatalytic performance by enhancing available electrocatalytic sites and rapid charge transmission channels. The developed electrode was characterized using XRD, XPS, and SEM studies to substantiate the formation of Ru-Pi/PDABA/CFP hybrid material, and electrochemical studies further evidence the improved electrochemical performance upon electrode modification. Cyclic voltammetric studies showcased 2-fold enhanced catalytic activity of Ru-Pi/PDABA/CFP compared to the bare CFP. Differential pulse voltammetric outcome corroborated outstanding electroanalytical metrics towards 2,4-DCP, unveiling an appreciably minimal limit of detection (LOD) of 1.47 nM and a low quantification boundary (LOQ) of 4.37 nM in a wide concentration-response linearity of 5 450 nM. The interferences from foreign substances produced only negligible signal modulations (<4.6 %) on the current amplitude of 2,4-DCP, validating the sensor's excellent selectivity towards the target analyte. Further, the application of Ru-Pi/PDABA/CFP was extended for the 2,4-DCP assay in actual tap and lake water samples. 2025 -
Rv1899c, an HDAC1ZBTB25-Interacting Protein of Mycobacterium tuberculosis, Promotes Stress Resistance and Immune Evasion in Infected Macrophages
Rv1899c, a previously identified HDAC1ZBTB25-interacting protein of Mycobacterium tuberculosis, plays a crucial role in bacterial adaptation and immune modulation. Recombinant M. smegmatis-expressing Rv1899c (MS_ Rv1899c) showed enhanced survival under acidic and oxidative stress compared to vector controls, along with improved early intracellular growth in THP1-derived macrophages. This was accompanied by reduced reactive oxygen species (ROS), diminished cytokines associated with inflammation and downregulation of autophagy proteins ATG5, Beclin, and LC3, which ultimately skewed the immune response, suppressing the pro-inflammatory M1 macrophage population. Targeting Rv1899c with 3-aminobenzamide (3-AB) impaired intracellular bacterial survival and restored IL-12B expression, while its combination with the HDAC inhibitor C1994 significantly enhanced bacterial clearance. Structural modelling confirmed the high stereochemical quality of the Rv1899c macrodomain, and computational studies identified 3-AB as the strongest ligand (?5.75 kcal/mol), stabilized through hydrogen bonding and hydrophobic interactions with key residues. Molecular dynamics simulations conducted for 200 ns demonstrated stable proteinligand interactions with consistent parameters, while MM/GBSA analysis indicated favourable binding energy (?G_bind = ?6.6 kcal/mol), largely influenced by van der Waals and electrostatic forces. Together, these findings highlight Rv1899c as a mediator of stress resistance and immune evasion and propose it as a potential therapeutic target against M. tuberculosis. 2025 by the authors. -
Ryu controller's scalability experiment on software defined networks
Software defined networks is the future of Computer networks which claims that traditional networks are getting replaced by SDN. Considering the number of nodes everyday connecting to the global village of internet, it becomes inevitable to adapt to any new technology before testing its scalability in presence of dynamic circumstances. While a lot of research is going on to provide solution as SDN to overcome the limitations of the traditional network, it gives a call to research community to test the applicability and caliber to withstand the fault tolerance of the provided solution in the form of SDN Controllers. Out of the existing multiple controllers providing the SDN functionalities to the network, one of the basic controllers is Ryu Controller. This paper is a contribution towards performance evaluation of scalability of the Ryu Controller by implementing multiple scenarios experimented on the simulation tool of Mininet, Ryu Controller and iPerf. Ryu Controller is tested in the simulation environment by observing throughput of the controller and checked its performance in dynamic networking conditions over Mesh topology by exponentially increasing the number of nodes until it supported tested on high end devices. 2018 IEEE. -

Saccharomyces - eukaryotic probiotic for human applications
Probiotics are viable microorganisms which are meant to confer health benefits to host after ingestion. Any probiotic strain has a special characteristic to survive in the extremely acidic and hostile conditions of stomach and intestine. Among all the commercially available probiotic strains, prokaryotes constitute the bulk of it, with quite a few belonging to eukaryotic yeasts. Eukaryotic probiotics are very limited and currently there are only two yeast strains (Saccharomyces boulardii and Kluyveromyces sp.), which are approved for human consumption and are available commercially in market. S. boulardii has been reported to have tremendous therapeutic potential. The main mechanism of action for S. boulardii includes strong antagonistic effect against a number of enteric pathogens, trophic effects on the intestinal mucosa, neutralisation of bacterial toxins as well as modification of host cell signaling pathways involved in inflammatory and non-inflammatory intestinal disease. Pertaining to these advantages, S. boulardii have been reported to be exceptionally effective against diarrheal diseases and intestinal inflammatory conditions including inflammatory bowel disease (IBD). Increasing scientific reports confirming the therapeutic potential of eukaryotic probiotics and their advantages over prokaryotic probiotic strains have dramatically increased the worldwide interest in these probiotics. 2019 Scrivener Publishing LLC. -
