The impact of slip mechanisms on the flow of hybrid nanofluid past a wedge subjected to thermal and solutal stratification
This investigation aims to inspect the flow and thermal characteristics of hybrid nanoparticles under the effect of thermophoresis and Brownian motion. The hybrid nanofluid is formed by dispersing the silver nanoparticles into the base fluid composed of tungsten oxide and water. The resulting hybrid nanofluid is assumed to flow over a moving wedge. The wedge is a geometry that can be commonly seen in many manufacturing industries, moulding industries, etc., where friction creates more heat and cooling becomes a necessary process. This study currently focuses on such areas of the industries. In this regard, the flow expressions in the form of Partial Differential Equations (PDEs) are obtained by incorporating the modified Buongiorno's model and using boundary layer approximations. The modified Buongiorno model helps us analyze the impact of volume fraction along with the slip mechanisms. Suitable transformations are used to achieve the nondimensional form of governing equations, and further, it transforms the PDE to Ordinary Differential Equation (ODE). The RKF-45 is used to solve the obtained ODE and the boundary conditions. Furthermore, graphic analysis of the solutions for fluid velocity, energy distributions and dimensionless concentration is provided. It was noted that the behavior of the Nusselt and Sherwood numbers was determined by analyzing numerous parameters. The conclusions show that they decrease with greater values of the stratification factors. Additionally, with higher values of the wedge parameter, the magnitude of the velocity field and the thermal boundary layer diminish. 2023 World Scientific Publishing Company. -
Adopting Metaverse as a Pedagogy in Problem-Based Learning
Pedagogical practices vary from time to time based on the requirement of various academic disciplines. Course instructors are constantly searching for inclusive and innovative pedagogies to enhance learning experiences. The introduction of Metaverse can be observed as an opportunity to enable the course instructors to combine virtual reality with augmented reality to enable immersive learning. The scope of immersive learning experience with Metaverse attracted many major universities in the world to try Metaverse as a pedagogy in fields such as management studies, medical education, and architecture. Adopting Metaverse as a pedagogy for problem-based learning enables the course instructors to create an active learning space that tackles the physical barriers of traditional pedagogical practices of case-based learning facilitating collaborative learning. Metaverse, as an established virtual learning platform, is provided by Meta Inc., providing the company a monopoly over the VR-based pedagogy. Entry of other tech firms into similar or collaborative ventures would open up a wide array of virtual reality-based platforms, eliminating the monopoly and subsequent dependency on a singular platform. The findings of the study indicate that, currently, the engagements on Metaverse are limited to tier 1 educational institutions worldwide due to the initial investment requirements. The wide adoption of the Metaverse platform in future depends on the ability of the platform providers to bridge the digital gap and facilitate curricula development. 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG. -
Pemetrexed loaded gold nanoparticles as cytotoxic and apoptosis inducers in lung cancer cells through ROS generation and mitochondrial dysfunction pathway
Supramolecular nanoparticles containing peptides and drugs have recently gained recognition as an effective tumor treatment drug delivery system. A multitarget drug termed pemetrexed is effective against various cancers, including nonsmall cell lung cancer. The work aims to establish the capability of pemetrexed gold nanoparticles (PEM-AuNPs) to induce apoptosis and explore molecular changes. X-ray diffraction, Fourier-transform infrared spectroscopy, ultravioletvisible spectroscopy, scanning electron microscope, and transmission electron microscope were used to investigate the synthesized nanoparticles. The MTT assay was utilized to investigate the anticancer properties of PEM-AuNPs at varying concentrations (50, 100, and 200M). PEM-AuNPs demonstrated a decrease in cell viability with 55.87%, 43.04%, and 25.59% for A549 cells and 54.31%, 37.40%, and 25.84% for H1299 cells at the respective concentrations. To assess apoptosis and perform morphological analysis, diverse biochemical staining techniques, including acridine orange-ethidium bromide and 4?,6-diamidino-2-phenylindole nuclear staining assays, were employed. Additionally, 2?,7?-dichlorofluorescein diacetate staining confirmed the induction of reactive oxygen species generation, while JC-1 staining validated the impact on the mitochondrial membrane at the IC50 concentration of PEM-AuNPs. Thus, the study demonstrated that the synthesized PEM-AuNPs exhibited enhanced anticancer activity against both A549 and H1299 cells. 2024 International Union of Biochemistry and Molecular Biology, Inc. -

Rayleigh-benard and benard-marangoni convection in micropolar fluid
We study in this thesis, Rayleigh-Bard and Bard-Marangoni convection in a micropolar fluid. We study the effects of temperature modulation at the boundary and gravity modulation in the presence of porous medium. The effects of rotation and internal heat generation are also investigated and results are presented graphically and discussed qualitatively. The problem presented in this thesis throws light on externally controlled internal convection in a micropolar fluid. These problems have many possible applications in geophysics, astrophysics, oceanography engineering and in space situations with g-jitter connected with gravity stimulation study. With this motivation, we examine in this thesis five problems and their summary is given below one by one. (i) THE EFFECT OF IMPOSED TIME-PERIODIC BOUNDARY TEMPERATURE AND POROUS MEDIUM ON THE ONSET OF RAYLEIGH-BARD CONVECTION IN A MICROPOLAR FLUID The analysis of buoyancy driven convection in a micropolar fluid saturated porous layer heated from below and subject to temperature modulation is presented. In addition to a steady temperature difference between the walls of the porous layer, a time-dependent periodic perturbation is applied to the wall temperatures. The small amplitude of the modulation is used to compute the critical Rayleigh number and critical wave number. Three cases of the oscillating temperature field are examined: (a) symmetric, so that the wall temperatures are modulated in phase, (b) asymmetric, corresponding to out-of-phase modulation, and (c) only the bottom wall is modulated. Possibilities of the occurrence of subcritical instabilities are also discussed. The shift in the critical Rayleigh number is calculated as a function of frequency and it is found that it is possible to advance or delay the onset of convection by time modulation of the wall temperatures. (ii)LINEAR AND NON-LINEAR ANALYSES OF GRAVITY MODULATION ON THE ONSET OF RAYLEIGH-BARD CONVECTION IN A MICROPOLAR FLUID WITH POROUS MEDIUM. -

Determinants and Impacts of Mergers and Acquisitions in the Drugs and Pharmaceutical Industry in India
Mergers and Acquisitions (MandAs) are inorganic growth strategies adopted by firms for achieving the objective of long-term growth maximization. Compared to other inorganic growth strategies like joint ventures and strategic alliances, MandAs offer deeper restructuring opportunities and better control over business over a long-term newlinebasis. During the third wave of globalization which started in early 1990s, MandAs became a popular strategy for firms to expand their businesses beyond the national boundaries. newlineIndian economy has been witnessing buzzling activity in the MandA landscape. A sectoral analysis of MandA trends identifies pharmaceutical sector as one of the top 5 newlinesectors with the highest MandA deal values during the period 2013-2016. Though Pharma sector has witnessed a decline in deal values during few years in the recent past, the resilience of the sector is visible through its ability to bounce back with record newlinebreaking deal values. Due to the continuous regulatory changes occurring in the domestic and foreign markets, pharma companies have to constantly change their strategies to survive and grow in the industry. MandAs enable pharma companies to adapt to these changes quickly. This study explores how the firms in the pharmaceutical sector use MandA as a strategy to navigate through the dynamic competitive landscape. The objectives of this research are threefold developing an understanding of the motives behind MandA decisions of the pharma firms, identification of the firm level determinants of acquisition probability and assessment of impact of MandAs. This study newlineuses qualitative content analysis for identification of MandA motives. The firm level newlinedeterminants of acquisition probability have been explored using Random Effect Logistic (REL) regression using panel data. Case study approach has been employed to assess the MandA impact by comparing the MandA motives with the post MandA outcomes. -
Training multi-layer perceptron with enhanced brain storm optimization metaheuristics
In the domain of artificial neural networks, the learning process represents one of the most challenging tasks. Since the classification accuracy highly depends on the weights and biases, it is crucial to find its optimal or suboptimal values for the problem at hand. However, to a very large search space, it is very difficult to find the proper values of connection weights and biases. Employing traditional optimization algorithms for this issue leads to slow convergence and it is prone to get stuck in the local optima. Most commonly, back-propagation is used for multi-layer-perceptron training and it can lead to vanishing gradient issue. As an alternative approach, stochastic optimization algorithms, such as nature-inspired metaheuristics are more reliable for complex optimization tax, such as finding the proper values of weights and biases for neural network training. In this work, we propose an enhanced brain storm optimization-based algorithm for training neural networks. In the simulations, ten binary classification benchmark datasets with different difficulty levels are used to evaluate the efficiency of the proposed enhanced brain storm optimization algorithm. The results show that the proposed approach is very promising in this domain and it achieved better results than other state-of-the-art approaches on the majority of datasets in terms of classification accuracy and convergence speed, due to the capability of balancing the intensification and diversification and avoiding the local minima. The proposed approach obtained the best accuracy on eight out of ten observed dataset, outperforming all other algorithms by 1-2% on average. When mean accuracy is observed, the proposed algorithm dominated on nine out of ten datasets. 2022 Tech Science Press. All rights reserved. -
