Beyond the Surface, Delving into du?kha: Buddhist Insights into the Lives of Married Women in a South Indian Metropolis
The modern era has brought women unparalleled opportunities in various fields. However, they still encounter numerous challenges that impede their well-being. This qualitative study explores how Buddhist wisdom can be applied to understand the well-being challenges experienced by married women aged 2539years and residing in Bengaluru, a metropolitan city in India. The study involved conducting semi-structured interviews with eight married women. A thematic analysis of these interviews revealed three main themes, that is, my body, my mind, and my relationship, each with sub-themes falling under the overarching global theme, echoes of unease: unveiling du?khas reflections. The factors driving unsatisfactoriness among the participants were then analysed by applying the Buddhist doctrine of dependent arising to understand the origins of du?kha. This study suggests that Buddhist philosophy provides valuable insights for unravelling the intricacies of the modern womans du?kha and may serve as a potential pathway for women to tap into their inner reservoir of wisdom and compassion, enhancing their overall well-being.

Interaction of Nanomaterials with Plant Macromolecules: Nucleic Acid, Proteins and Hormones
Nanotechnology has the ability to change a wide range of industrial and agricultural operations. To harness these possibilities, it is essential to construct nano-materials that have minimum impact on the human body, plant systems as well as the environment. Using different materials can up-or down-regulate diverse genes of plants, create stimulating or stressful conditions and even cause production of metabolites that affect plant-associated microbes. The same nanoparticle can promote one plant species growth and be toxic to another. A small change in the concen-trations could cause either flourishment or senescence. It is crucial to understand how nanomaterials interact with nucleic acids, the most fundamental plant macro-molecule, as well as with the proteins and hormones made by biochemical processes. This chapter explores the basics of nanotechnology, with a brief classification and notes on some of the most recently used nanomaterials in agriculture such as metals and their oxides, quantum dots, graphene, arabinoxylan and chitosan nanoparticles, single and multi-walled carbon nanotubes. Interactions with these above-mentioned macromolecules are explored, along with futuristic applications in plants that are currently being tested, like nanocarriers and nanovalves. Through this work, it is hoped that the field will further be extended through proper understanding of the environmental implications of nanomaterials, and that green technology will become the norm.

SCSLnO-SqueezeNet: Sine Cosine-Sea Lion Optimization enabled SqueezeNet for intrusion detection in IoT
Security and privacy are regarded as the greatest priority in any real-world smart ecosystem built on the Internet of Things (IoT) paradigm. In this study, a SqueezeNet model for IoT threat detection is built using Sine Cosine Sea Lion Optimization (SCSLnO). The Base Station (BS) carries out intrusion detection. The Hausdorff distance is used to determine which features are important. Using the SqueezeNet model, attack detection is carried out, and the network classifier is trained using SCSLnO, which is developed by combining the Sine Cosine Algorithm (SCA) with Sea Lion Optimization (SLnO). BoT-IoT and NSL-KDD datasets are used for the analysis. In comparison to existing approaches, PSO-KNN/SVM, Voting Ensemble Classifier, Deep NN, and Deep learning, the accuracy value produced by devised method for the BoT-IoT dataset is 10.75%, 8.45%, 6.36%, and 3.51% higher when the training percentage is 90. 2023 Informa UK Limited, trading as Taylor & Francis Group. -
Impact of domestic investment, market size, and trade openness on outward fdi: A panel data analysis on brics
The recent phenomenal increase in the outward foreign direct investment (FDI) of emerging countries has raised concerns among policymakers. One school of thought argues that when multinational firms relocate production facilities abroad, it reduces the likelihood of concurrent investments in the home country, resulting in reduced domestic output. In this case, the outward FDI would harm the domestic investments. The other argues that the outward FDI would be more advantageous for the domestic investment when firms internationalize for entering into new markets and/or to import intermediate goods, wherein outward investments boost the returns in the home country, leading to a positive impact of outward FDI on domestic investment. The influence of the outward FDI on the domestic investment of any country or a region state cannot be generalized as each country is unique, and the drivers of investments would differ for different countries at the different development phases of each country. An attempt was made in this study to empirically trace the impact of the domestic investment, market size, and trade openness of the BRICS's members on the BRICS's outward FDI as a group. The results of the panel least square method highlighted that the variables - domestic investment and trade openness of BRICS had a positive effect on the outward FDI; whereas, the market size of BRICS was inversely related to outward FDI of BRICS. The data were tested for stationarity and Hausman test validated the results. 2019, Associated Management Consultants Pvt. Ltd.. All rights reserved. -

Bacterial diversity of geochemically distinct hot springs located in Maharashtra, India
Bacterial diversity of four thermally different hot springs of Ratnagiri district, Maharashtra, India, was investigated using culture-dependent and culture-independent approaches. A total of 144 bacterial cultures were isolated and identified using MALDI-TOF MS (matrix-assisted laser desorption ionization-time of flight mass spectrometry) and 16S rRNA gene sequencing. Culture-independent analysis by Ion Torrent sequencing targeting the V3 region of the 16S rRNA gene revealed the predominance of Firmicutes across all the hot springs, followed by Chloroflexi, Bacteroidetes, Cyanobacteria, Proteobacteria, Armatimonadetes, Actinobacteria, Nitrospirae, Acidobacteria, and DeinococcusThermus, with subtle differences in their abundance. At the lower taxonomic rank of genus, we noted the prevalence of Acinetobacter followed by Clostridium, Planomicrobium, Bacillus, Streptomyces, and Leptolyngbya. Metagenomics imputation using in silico approach revealed divergence in the metabolic capabilities of bacterial communities along the thermal gradient of host springs, with site TS (63C) featuring the abundant functional gene families. 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -
Global stability analysis of thermofluid convection in an inclined porous layer with viscous dissipation, throughflow, and local thermal non-equilibrium effects
The onset of thermal convection in an inclined porous medium under the effect of viscous dissipation with throughflow, using a local thermal non-equilibrium model, is investigated. Darcy's law is used to describe the flow. The stability of the flow is analyzed through linear and nonlinear analyses. A linear instability analysis of disturbances in the form of rolls is performed through the normal mode technique, while the energy method is applied for nonlinear stability analysis by defining an energy functional. The boundary eigenvalue problem that emerges in the two analyses is solved using the boundary value problem solver (bvp4c) in MATLAB R2023a. The impact of the inter-phase heat transfer parameter, H, the porosity-modified conductivity ratio, ? , inclination angle, ? , and the stability parameter, ? ? , on the critical Rayleigh value, R a c ? , is systematically analyzed. The accuracy of the linear instability thresholds are validated with those reported in the existing literature. The results of linear and nonlinear theories have been compared. The study reveals that the inter-phase heat transfer parameter enhances flow stability, while the inclination angle serves as a stabilizing factor in the linear analysis but as a destabilizing factor in the nonlinear analysis, indicating the possibility of sub-critical motion. The stability across all inclination angles depends on ? ? ; specifically, ? ? acts as a stabilizing influence at smaller inclinations but exhibits a monotonic destabilizing effect at larger inclination angles. 2025 Author(s). -

Inphase and outphase concentration modulation on the onset of magneto-convection and mass transfer in weak electrically conducting micropolar fluids
The paper analyses the effect of concentration modulation at the onset of solute magneto-convection and heat transfer in a weak electrically conducting fluid by carrying out a linear and non-linear analysis. The Venezian approach is assented encompassing the correction Solute Rayleigh number and wave numbers for meagre amplitude concentration modulation. A multiscale method is applied to convert the analytically untraceable Lorenz model to an analytically traceable Ginzburg-Landau equation which is solved to quantify mass transfer through Sherwood number. It is observed that concentration modulation results in sub-critical motion however out-of-phase concentration modulation is more stable compare to others. 2019 Author(s). -
Investigating the contrast diurnal relationship of land surface temperatures with various surface parameters represent vegetation, soil, water, and urbanization over Ahmedabad city in India
Many climatic problems have arisen due to congested and inefficient planning, reduced vegetation cover, and increased pollution from factories and vehicles. One such primary concern is increased land surface temperature (LST) contributes to the urban heat island (UHI) occurrence. This research aims to understand better the UHI effect in the region neighbouring the Indian city of Ahmedabad. MODIS sensor data (onboard Aqua and Terra platforms) and Landsat data were used for the study. The research was done for the summer, monsoon, and winter seasons in the research region, using data from thirteen years between 2003 and 2015. The current study looked at LSTs' spatial and temporal differences to assess the SUHI effect over Ahmedabad city. The association between diurnal LST and various surface variables such as vegetation, built-up, soil, water, and so on has also been examined. A variety of land surfaces influences the diurnal variations of LSTs. The diurnal associations of LST with vegetation, urbanization, soil, and water factors have been studied. The overall study of LST' relationship with all of the various parameters reveals a very significant dynamic relationship. 2022 The Author(s) -
In-phase, out-of-phase, bottom-wall two-frequency boundary temperature modulations on the onset of Rayleigh-Bard convection
The onset of convection in a Newtonian liquid-containing system is investigated using a two-frequency boundary temperature. The consequences of three types of two-frequency boundary temperature modulations have been thoroughly investigated: (i) in-phase, (ii) out-of-phase, and(iii) bottom-wall. The combined effect of two frequencies with sinusoidal and nonsinusoidal wave types is also documented under these various types of boundary temperature modulations. To facilitate the study, the Venezian method is approvedand the critical Rayleigh number and its correction are calculated. The parameters resulting from the study's two frequencies of modulation are the mixing angle, (Formula presented.), the amplitudes, (Formula presented.), and the set of coprime integers, (Formula presented.). The system's thermodynamics determines the range of these parameters. The research discovered that out-of-phase two-frequency boundary temperature modulation is the most stable, while in-phase is the least stable. Besides that, any combination of wave type with square wave type yields the most excellent stability. Furthermore, the two-frequency boundary temperature modulation is more stable than the single-frequency and no-modulation cases. 2022 Wiley Periodicals LLC. -
Comparative study of sinusoidal and non-sinusoidal two-frequency internal heat modulation in a Rayleigh-Bard system
A linear stability analysis is assented to investigate the effect of two-frequency internal heat modulation at the onset of convection in a Newtonian liquid. The correction Rayleigh number and wave number for small amplitudes is calculated using the Venezian approach. Under two-frequency internal heat modulation, the motion is found to be subcritical. To quantify heat transfer in the system, the three-mode Lorenz model is solved numerically. Various combinations of sinusoidal and non-sinusoidal waveforms influence the onset of convection and heat transfer in the system due to two-frequency internal heat modulation. The parameters' influence on heat transfer is seen to be dependent on the presence of a heat source or sink. 2021 Wiley Periodicals LLC. -
The onset of RayleighBard convection and heat transfer under two-frequency rotation modulation
The impact of 16 combinations of sinusoidal (sine) and nonsinusoidal (square, triangular, and sawtooth) time-periodic Coriolis force (rotation modulation) on RayleighBard convection in a Newtonian liquid is studied in this paper. This consideration is made to capture the possible effects of two-frequency rotation modulation on stability, that is, the onset of convection and the simultaneous amount of heat transfer in the system. The Venezian approach has been asserted on the linearized Lorenz model to derive the correction Rayleigh number as a function of the two frequencies. The Lorenz model with nonlinearities is evaluated numerically to assess the quantity of heat transfer in the system. The present study states that in comparison with existing studies of no-modulation and single-frequency rotation modulation, two-frequency rotation modulation yields higher stability bounds and thus diminishes the heat transfer. Heat transfer is found to be enhanced by a pair of coprime integers associated with the harmonics in the system. 2021 Wiley Periodicals LLC -

Fluorescent PVDF dots: from synthesis to biocidal activity
Infection by microorganisms is a serious concern in food storage, water purification, drugs, and particularly in biomedical devices. Long-term use of permanent implants often leads to its contamination due to pathogens. Timely tracking of bacterial activity and its interaction with antibodies are crucial for overcoming these infections. In this work, fluorescent polymeric biocides are obtained from a non-conjugated polymer polyvinylidene fluoride (PVDF), which is neither emissive nor known for its antibacterial activity. PVDF dot was synthesized via hydrothermal treatment eliminating the need for complicated and toxic preparation strategies. PVDF-based dot exhibits high fluorescence aroused from the carbogenic core due to the carbonization of the hydrocarbon chain. It is found that the dots were semiconducting contrary to the bulk form of PVDF. The photoluminescent polymer dots also exhibited an excellent antibacterial activity toward Escherichia coli (E.coli) and Streptococcus bacteria. This luminescence and biocidal activity of PVDF-derived dots have attractive applications in the field of fluorescent diagnostics and therapeutics.

A Review on Recent Trends in Biological Applications of Non-conjugated Polymer Dots
With the advancement of zero-dimensional carbon materials, carbon dots (CDs) have received immense attention owing to their exceptional optical properties, tailoring of size, and ease of functionalization. They have wide applications in fluorescent sensing, chemical sensing, bioimaging, photocatalysis, etc. Zero-dimensional polymer nanoparticles are called polymer dots (PDs) and are classified into conjugated and non-conjugated PDs based on their conjugated system. Non-conjugated polymer dots (NCPDs) do not have specific conjugated fluorophore groups, but they have superior chemical stability and water solubility than the conjugated PDs. The carbon core of NCPDs is surrounded by polymer chains containing ample functional groups such as C=O, N=O, and C=N, which are responsible for the luminescent PDs. NCPDs are less toxic, photostable, and biocompatible and are relevant in biological explorations in bioimaging, drug delivery, biosensing, etc. This mini-review provides a systematic overview of the inherent properties and the biological applications of NCPDs. It also emphasises the synergistic impacts on the optical performance of modified PDs and significant future research concerns.

Antimicrobial resistance (AMR) rising from nosocomial infections is an escalating threat to human life nowadays due to the overuse of drugs. The multidrug-resistant pathogenic bacteria have increased morbidity and mortality rates, becoming a crucial global clinical challenge. Gram-positive Staphylococcus aureus bacteria is one of the nosocomial pathogens that cause severe invasive diseases and skin infections to human health worldwide. Herein, a non-conjugated polymer dot (NCPD) was synthesized from less toxic and biocompatible polyvinyl alcohol (PVA) via hydrothermal treatment. The fluorescence of the polymer dots was enhanced by nitrogen doping. The as-synthesized nitrogen-doped polymer dots (PDs) exhibit excitation-dependent luminescence emission and show green color fluorescence under UV light. The average size of the synthesized functionalized non-conjugated polymer dot is obtained as 4.08nm, and they exhibit an amorphous structure. No antibacterial property was observed for bulk polymer, but the doped polymer dots showed antibacterial activity against Gram-positive Staphylococcus aureus bacteria.

Exploring the anti-inflammatory activities, mechanism of action and prospective drug delivery systems of tocotrienol to target neurodegenerative diseases
A major cause of death in the elderly worldwide is attributed to neurodegenerative diseases, such as AD (Alzheimers disease), PD (Parkinsons disease), ALS (Amyotrophic lateral sclerosis), FRDA (Friedreichs ataxia), VaD (Vascular dementia) etc. These can be caused due to multiple factors such as genetic, physiological problems like stroke or tumor, or even external causes like viruses, toxins, or chemicals. T3s (tocotrienols) exhibit various bioactive properties where it acts as an antioxidant, anti-inflammatory, anti-tumorigenic, and cholesterol lowering agent. Since T3 interferes with and influences several anti-inflammatory mechanisms, it aids in combating inflammatory responses that lead to disease progression. T3s are found to have a profound neuroprotective ability, however, due to their poor oral bioavailability, their full potential could not be exploited. Hence there is a need to explore other drug delivery techniques, especially focusing on aspects of nanotechnology. In this review paper we explore the anti-inflammatory mechanisms of T3 to apply it in the treatment of neurodegenerative diseases and also discusses the possibilities of nano methods of administering tocotrienols to target neurodegenerative diseases.
