Item Unravelling the potential of 2-(Bromo/polybromophenylamino) substituted-4-arylthiazoles: Synthesis, characterization, anticancer, antimicrobial, molecular docking, and ADMET studies(2026) Kumar, AmanA total of twenty-four 2-(bromo/dibromo/tribromophenylamino)-4-arylthiazole derivatives (3a-x) were pre pared to explore their biological potential, particularly to evaluate the effect of bromine substituent(s) on the phenylamino group attached at position-2 of the thiazole nucleus. The reaction of α-bromoacetophenones with different N-bromoarylthioureas at room temperature in alcohol afforded the target products in good yields. Their structures were established based on analysis of spectroscopic data and results of single-crystal X-ray diffraction technique. The anticancer evaluation revealed that compound 3p exhibited excellent selectivity (SI =8.86) with an IC50 value of 129.37 ±8.0 μM toward lung cancer cells (A549), surpassing the standard drug, Carboplatin (IC50 =128.83 ±2.0 μM, SI =1.21). It was observed that compounds possessing a 2,4-dibromophenylamino moiety linked at position-2 of the thiazole ring demonstrated the highest selectivity for A549 cells and the lowest cytotoxicity against Vero cells. Antimicrobial screening revealed that compounds 3g and 3h were highly effective against the bacterial strain, Staphylococcus aureus, and the fungal strain Candida albicans, with MIC values of 0.038 μg/mL (Ampicillin =1 μg/ml) and 0.021 μg/ml (Fluconazole =0.31 μg/ml), respectively. Furthermore, molecular docking studies were conducted on the newly synthesized candidates, which support their potential as effective biological agents. ADMET analysis for key pharmacokinetic and toxicological prop erties of these compounds was also conducted to assess their drug-likeness nature.Item Two-walled phthalimide extended calix[4]pyrrole: Experimental and computational anion binding investigations(2026) Ahmed, MukhtarIn this study, a two-walled phthalimide extended C4P (11) was probed as an anion receptor for tetrabuty lammonium (TBA) salts of spherical halides, trigonal/tetrahedral oxoanions and linear anions with the aid of DFT/TD-DFT calculations and UV-vis spectroscopy. Optimized geometries indicate the non-covalent interaction present between the guest and host. Interestingly, anion receptor complex (11@F ) has been found more reactive among various studied anion receptor complexes. Furthermore, TD-DFT analyses provided insights into elec tronic transitions within the studied species and found the absorption spectra in the range of 180 nm to 400 nm. UV-vis absorbance titrations of receptor 11 with various anions in CH 3 CN have revealed 1:1 binding stoichi Oxoanions ometry and considerably higher binding affinities with F‾, Cl‾, CH 3 COO‾, and SCN‾ as compared to the one- walled phthalimide C4P (13) and simple C4P (1) existing in the literature. Notably, higher anion binding af f inities of the receptor 11 as compare to the C4Ps 1 and 13 certifies the contribution of weaker anion in teractions from phthalimide subunits as well as the CH–anion interactions from the aliphatic methylene (CH protons besides primary hydrogen bonding of the pyrrolic NHs-anions as observed from 1 π H NMR studies.Item Tuning electrochemical properties of Ni–Co MOF/MWCNTs composite via electrolyte optimization(2026) Singh, PratapIn pursuit of global energy demand the advancement of effective and eco-friendly electrode material is needed. In this study Ni–Co MOF/ MWCNTs composite was synthesized by solvothermal approach and was studied in various electrolytes (6 M KOH, 6 M LiCl, and 1 M Na2SO4) and their assessment was done via electrochemical approach using Cyclic Voltammetry (CV) for finding specific capacitance, Galvanostatic Charge Discharge (GCD) for determining energy density and power density, and Electrochemical Impedance Spectroscopy (EIS) studies to find solution and charge transfer resistance. GCD studies revealed the distinct behaviors based on ion properties, with KOH showing the highest ionic conductivity and capacitance retention (87.3 % at 4 Ag 1). The specific capacitances (F g 1), at 2 mVs 1, were 1157.4 (KOH), 1022.3 (LiCl), and 736.5 (Na2SO4). The energy density and power density, at a current density of 0.5 A g 1, were 205.90 Wh kg 1 and 249.2 W kg 1, respectively (in 6 M KOH). The capacitive retention of the composite Ni–Co MOF/MWCNT material is 87.3 % in 6 M KOH over 10,000 cycles The study align with sustainable development goals (SDG7), focused on affordable, clean energy production and storage.Item Thermoelectric Performance of CrSSe and CrSeTe Janus Monolayers(2026) Srivastava, SunitaIn this work, density functional theory-based simulation is used for investigating the structural and electronic properties of Janus monolayers CrSSe and CrSeTe. Electronic bandgap values of 0.85 eV and 0.62 eV are obtained for CrSSe and CrSeTe, respectively. Further, the semiclassical Boltzmann theory is used for assessing the thermoelectric parameters including the Seebeck coefficient, electrical and thermal conductivity, and thermoelectric performance (ZT) of the monolayers. The values of Seebeck coefficient and lattice thermal conductivity for (n-type) p-type Janus monolayers CrSSe and CrSeTe are (1340) 1390 µV K−1, (971) 1010 µV K−1, and (11.01) 0.25 W/K, respectively. The ZT values for (n-type) p-type Janus monolay ers CrSSe and CrSeTe are (0.92) 0.93 and (0.95) 0.96, respectively, at room temperature. The thermoelectric performance of these monolayers is higher than for the homogeneous CrSe2 monolayer due to their unique structural and compositional characteristics. These results contribute valuable insights for the design and optimization of Janus monolayers for advanced thermoelectric applications, and pave the way for promising advancements in sustainable energy harvesting.Item Structural and photophysical investigation of gadolinium based Eu3 + doped Gd3GaO6 phosphor: A red emitter with high color purity for WLEDs application(2026) Kumar, HarishTo understand different properties of Eu3+ions in inorganic phosphors, a series of red emitting Gd3GaO6:Eu3+ was synthesized via solution combustion method. XRD patterns supported by Rietveld refinement revealed successful formation of crystalline sample with orthorhombic structure and Cmc21 space group. Microstructural features and elemental mapping of samples were examined by means of FE-SEM and EDX techniques. Photo luminescence spectra of Eu3+-activated Gd3GaO6 revealed red emission at 612 nm due to the 5D0→7F2 transition under excitation at 261 nm. A decrease in emission intensity was observed after doping levels exceed 4 mol% indicating energy transfer between activator ions results in concentrating quenching governed via dipole-dipole interactions. The intensity parameters Ω2 and Ω4 defined by Judd Ofelt theory were calculated utilizing emission spectra to investigate coordination symmetry around Eu3+ions. The photoluminescence decay profile was well described by bi-exponential decay function. The activation energy 0.19873 eV suggests good thermal stability of GGO:4 mol% Eu3+phosphor. The high color purity (98.15 %) inferred from CIE coordinates revealed their applicability in white light emitting diodes.Item Stimuli-responsive supramolecular gels from fatty acid amides for theophylline delivery and anticancer applications ☆(2026) Babu, Yangala SudheerSupramolecular gels derived from low-molecular-weight gelators (LMWGs) uniquely combine features of both homogeneous and heterogeneous systems, making them highly valuable in synthetic and medicinal chemistry. Their rising prominence in cancer therapy is attributed to their excellent biocompatibility, stimuli-responsive behavior, and ability to deliver anticancer drugs directly to tumor sites-reducing systemic side effects and improving treatment efficacy. In this study, a series of fatty acid amide-based gelators (3a-3h) were synthesized through a one-step amidation of 4-aminopyridine, with alkyl chain lengths varying from C 6 to C 22 . These gelators formed stable organo/hydrogels in DMSO/water at low minimum gelation concentrations (1 % w/v), qualifying as supergelators. Longer alkyl chains enhanced gelation and thermal stability due to synergistic interactions between amide groups and hydrophobic segments. Specifically, gelators 3e and 3h demonstrated effective encapsulation of the hydrophilic drug theophylline, facilitating controlled, pH-responsive release at physiological temperature without compromising drug integrity. Cytotoxicity assays of these gelators demonstrated promising anticancer activity against A549 lung cancer cells, along with low toxicity in normal Vero cells. Furthermore, the synergistic anticancer efficacy of the theophylline-loaded gel formulations (3e + Th and 3h + Th) showed enhanced potency, with IC 50 values of 12.89 ± 0.4 and 21.50 ± 2.8 potential as advanced drug delivery systems for cancer therapy. μ g/mL, respectively, highlighting theirItem Simulation based evaluation of neutrosophic exponential imputations of population mean using neutrosophic ranked set sampling(2026) Kumar, AnoopThe prevalence of missing values and uncertainty in real-world dataset often hinders accurate analysis and reliable conclusions. Existing approaches often struggle to effectively address both aspects simultaneously. To handle both these aspects simultaneously, this paper proposes an approach that combines neutrosophic theory with exponential imputation and provides neutrosophic exponential imputations for estimating population mean using neutrosophic ranked set sampling (NRSS) framework. Neutrosophic imputation structures utilize the strengths of neutrosophic logic to manage uncertainty inherent in the data and incorporates NRSS to improve the efficiency of the imputation process. The mathematical properties such as bias and mean square error (MSE) of the proposed neutrosophic exponential estimators are obtained. The proposed neutrosophic exponential imputations are compared with some adapted prominent neutrosophic imputations. A thorough simulation study demonstrates that neutrosophic exponential imputations outperform the adapted prominent imputation structures in terms of both accuracy and robustness in handling datasets characterized by both missingness and uncertainty. A real data application of the proposed imputation structures is also presented in support of the mathematical results as well as simulation findings.Item Risk assessment of uranium in groundwater surrounding the Greater Noida industrial area, Uttar Pradesh, India(2026) Kumar, SuneelGroundwater quality is an important concern for public health, particularly with respect to uranium contami nation, which may contribute to radiation dose and chemical toxicity when used for drinking. An analysis of radiation levels in groundwater has been undertaken around Noida, Uttar Pradesh, India, using the LED Fluo rimetry Technique. The concentration of uranium (U-238) in water samples obtained from submersible pumps, tube wells, and hand pumps in Noida is determined. The uranium concentration, averaging 10.62 with the annual effective dose of 1.77 μ Sv y 1 μ g L 1 , along , falls within the safety thresholds recommended by the World Health Organization (2004) and the Atomic Energy Regulatory Board (2004). The chemical toxicity and radiological impact of uranium in water have been assessed. To estimate radiation risks from natural radionu clides in groundwater, radiological health parameters were determined. Elevated activity levels of natural ra dionuclides in certain areas are attributed to factors such as regional geology, hydrology, and the nature of local industries.Item Neutrosophic imputation: a novel approach to population mean estimation under indeterminacy(2026) Kumar, AnoopAccurate population mean estimation is crucial in survey sampling, particularly when dealing with missing or partial data. The intrinsic uncertainty and indeterminacy found in these datasets frequently pose challenges for computational impu tation approaches. In this article, by including neutrosophic logic into the imputation process, some novel neutrosophic imputation approaches and their corresponding resultant neutrosophic estimators for population mean estimation are pre sented along with their properties under simple random sampling (SRS). Neutrosophic logic offers a strong foundation for overcoming the drawbacks of conventional approaches because of its capacity to handle indeterminate and uncertain data. We show that the proposed novel neutrosophic imputation performs better than the conventional neutrosophic imputation approaches through comprehensive simulations and practical experiments. The simulation and practical results demon strate how the proposed approaches may be used to increase the precision of statistical studies, particularly in domains where ambiguity and partial data are common.Item IR radiated Upconversion in Ho & Yb doped MgO-Y for security ink application: Temperature sensing and laser-induced thermal effects(2026) Vij, AnkushThis study presents a comprehensive analysis of the novel composition of Ho (0.1–1 mol%) and Yb (0.5–20 mol %) co-doped MgO-Y₂O₃ nanocomposites for upconversion (UC) and downconversion (DC) luminescence appli cations. The nanocomposites were synthesized using a cost-efficient combustion method. X-ray diffraction (XRD) confirmed stable MgO and Y₂O₃ phases, with peak shifts and unit cell parameter variations correlating with increased dopant (Ho, Yb) concentrations. Transmission electron microscopy (TEM) revealed particle agglom eration along with clear lattice fringes, while selected area electron diffraction (SAED) confirmed well-defined ring patterns characteristic of MgO and Y₂O₃ crystals. Photoluminescence (PL) spectroscopy revealed strong green, red, and near-infrared (NIR) emissions under both 448 nm (downconversion; DC) and 980 nm (upcon version; DC) excitations. Power-dependent PL studies indicated three-photon absorption for green and two- photon absorption for red/NIR emissions. Notably, the intensity of the green emission saturates rapidly at 5 mol% Yb 3+ and Yb 3+ , while red emission saturation occurs at 15 mol%, indicating efficient energy transfer between Ho 3+ ions. Power-dependent PL studies unveiled a three-photon absorption mechanism for green emissions and two-photon absorption for red and NIR emissions. Temperature-dependent UC was examined over a range of 298 K to 683 K, demonstrating promising optical temperature sensing capabilities, with maximum sensitivity recorded at 51.3 × 10 4 K 1 at 298 K. Moreover, the nanocomposites exhibited excellent stability under pro longed laser exposure, underscoring their potential for practical applications. Power-dependent tunable colori metric parameters further highlighted their suitability for warm and cool LED technologies. Finally, the successful demonstration of these nanophosphors as security inks for anticounterfeiting applications opens new possibilities for advanced security solutions.Item Investigating the photocatalytic performance of ternary nanocomposite Pd/ rGO/MoO₃ under visible light(2026) Kumar Yogesh, GauravTwo-dimensional (2D) ternary nanocomposites that integrate noble metal nanoparticles with semiconductor oxides on conductive carbon frameworks have emerged as efficient photocatalysts due to their enhanced charge separation, broad light absorption, and surface reactivity. In this work, a Pd/rGO/MoO₃ ternary nanocomposite was synthesized via a one-step hydrothermal method by anchoring palladium (Pd) nanoparticles and MoO₃ nanorods on reduced graphene oxide (rGO) sheets. Comprehensive structural, morphological, and chemical characterizations (UV–Vis spectroscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectros copy, Field-emission scanning electron microscopy, and transmission electron microscopy) confirmed the suc cessful integration and strong interfacial contact among the three components. Photocatalytic tests under visible light demonstrated that the Pd/rGO/MoO₃ nanocomposite exhibited significantly improved degradation of methylene blue (MB) dye (89 % within 60 min) compared with Pd (52 %), Pd/rGO (72 %), and rGO/MoO₃ (77 %) counterparts. This superior activity arises from the synergistic effects of Pd plasmonic enhancement and electron-trapping ability, rGO high conductivity and large surface area, and MoO₃ strong oxidative potential, which collectively promote efficient charge separation and reactive oxygen species generation. Moreover, the catalyst maintained an efficiency of 82–89 % over five reuse cycles, confirming its high stability and recycla bility. These findings emphasize the future promise of Pd/rGO/MoO₃ as a robust, visible-light-driven photo catalyst for real wastewater and dye degradation, as well as other environmental remediation applications.Item Investigating entrance channel effect through the measurement of neutron multiplicity in mass region a ≈200(2026) Agrawal, AviteshIn this study, we measured both the pre-scission and post-scission neutron multiplicities for the 31P + 170Er reaction at excitation energies in the range of 62-84 MeV, using the National Array of Neutron Detectors (NAND) at Inter University Accelerator Centre (IUAC), New Delhi. Theoretical calculations to reproduce the measured neutron multiplicities have been performed using the dynamical model code VECLAN. These calculations show that the dissipation strength parameter (𝛽) increases with excitation energy. Dynamical model calculations also have been performed using HICOL code to understand the fusion dynamics and formation time. It has been observed that transitioning from an asymmetric to a symmetric entrance channel leads to a gradual increase in the compounItem Inference on inverted exponentiated Rayleigh data from accelerated life testing with hybrid censoring(2026) Yadav, PriyaThis paper addresses the problem of estimating unknown parameters of the inverted exponentiated Rayleigh distribution within the context of accelerated life testing. We consider lifetime data observed through step- stress and type-I hybrid censoring, and incorporate the cumulative expo sure model assumptions to establish connections between the distribu tion at various stress levels. We then write the associated likelihood function based on the observed data and derive maximum likelihood estimators for the distribution’s unknown parameters. Furthermore, employing a Bayesian approach, we initially adopt gamma priors and compute posterior distributions for the parameters. These posterior dis tributions are then utilized to calculate Bayesian estimates using the squared error loss function. To assess the performance of maximum like lihood and Bayesian estimates, we conduct a simulation study under various scenarios, considering both non-informative and informative priors. We also evaluate interval estimates and coverage percentages under both classical and Bayesian approaches. Finally, for illustrative purposes, we analyze two real data sets, demonstrating the practical application of our proposed methodology.Item Impact of separator on the electrochemical performance of g-C3N4/Co3O4 nanohybrid symmetric supercapacitors(2026) Vij, AnkushThe present study aims to evaluate the influence of different separators on the electrochemical performance of a 2D g-C3N4 decorated Co3O4 symmetric supercapacitor. Exfoliated graphitic carbon nitride (ECN) was combined with Co3O4 to create nanocomposites in weight ratios of 1:0.01, 1:0.05, and 1:0.1 (COCN1, COCN2, COCN3). XRD analysis revealed that the ECN possesses a hexagonal structure, while Co3O4 exhibits a cubic spinel structure. COCN nanocomposites have been successfully synthesized, as confirmed by analyses using XRD and FTIR techniques. HR-TEM and SAED indicated that the CO3O4 adhered to the g-C3N4 matrix. The BET analysis revealed that the ECN and COCN2 show specific surface areas of 25 m2/g and 35 m2/g, respectively. The COCN2 nanocomposites attain a specific capacitance of 667.8 F/g at 1 A/g in 1.0 M KOH electrolyte, which is eight times more than ECN, due to the combined effects of the nitrogen content and cobalt oxidation states. The COCN2 exhibits an energy density of 45.45 Wh/kg at 218.75 W/kg power density, with 99.5 % capacitive retention. To explore the influence of different separators in symmetric devices, COCN2 was employed within the Swagelok assembly, featuring two separate types of separators: Whatman paper (COCN2/W/COCN2) and PVA-KOH gel electrolyte (COCN2/GE/COCN2). The COCN2/W/COCN2 device achieved a specific capacitance of 197.25 F/g at a current density of 1.0 A/g. Furthermore, it attained an energy density of 140.27 Wh/kg at a power density of 1600 W/kg, while retaining 94.23 % of its initial capacitance. In contrast, the COCN2/GE/COCN2 device showed a specific capacitance of 69.25 F/g and an energy density of 24.62 Wh/kg at 1600 W/kg, maintaining 95.4 % of its capacitance after 1000 cycles. The synergistic combination of Co3O4 and g-C3N4 offers a promising strategy for enhancing energy.Item DFT and TDDFT investigations of photovoltaic properties of triphenylamine based dyes: Impact of π based redox shuttle -spacer tuning for DSSC with iodine and copper(2026) Malhotra, Sumit SahilA series of dyes with a donor π-acceptor (D π-A) framework based on triphenylamine (TPA) were theoretically designed to enhance the photovoltaic performance of dye-sensitized solar cells (DSSCs). Based on an experi mentally reported TPA dye containing a benzo[c][1,2,5] thiadiazole(Dye1) modelled by including benzo[c]thiophene(Dye2), 4,4 ′ π-spacer, five new dyes were -bibenzo[c]thiophene(Dye3), 2H-benzo[d][1,2,3]triazole ′ H-4,4 ′ (Dye4), 2H,2 azole(Dye6) as π-bibenzo[d][1,2,3]triazole(Dye5), and 4-(benzo[c]thiophen-4-yl)-2H-benzo[d][1,2,3]tri--spacers. Density Functional Theory and Time-Dependent Density Functional Theory were employed to study their electronic structures, charge transfer properties, and photovoltaic performance. All dyes showed negative Gibbs free energy for electron injection into TiO 2 , signifying favourable charge transfer. The dye2 with benzo[c]thiophene spacer exhibited the highest open-circuit voltage, while those with dye5 and dye6 showed faster regeneration, particularly with copper-based redox shuttles. These candidates demonstrated high light-harvesting efficiency and ideal energy alignment, indicating their potential for high-efficiency DSSCs. These f indings show that the π-spacer tuning is an effective strategy for optimizing dye performance in DSSCs.Item CuO/NiO-doped ordered mesoporous carbon for high-performance photocatalytic degradation of dye and energy storage application(2026) Kumar, HarishAdvanced nanomaterials with optimized structures, surfaces, porous characteristics, optimum band gaps, and compositions are crucial for wastewater treatment and energy storage applications. Here, we report the soft- template synthesis of CuO/NiO-doped ordered mesoporous carbon (OMC/CuO/NiO), which exhibits a syner gistic enhancement in photocatalytic and electrochemical performance. The structure testing verified the crea tion of regular mesoporous and effective doping of CuO and NiO into the Carbon framework. The photocatalytic activity of the nanocomposite studied was determined by means of the degradation of methylene blue (MB) dye in the presence of UV–visible light. Light absorption and enhanced charge separation increased the degradation efficiency of the OMC/CuO/NiO nanocomposite to 96 % (improved compared to pure OMC of 55.07 %) and facilitated light absorption and charge separation, respectively. In addition to photocatalysis, OMC/CuO/NiO nanocomposite electrode shows excellent performance as a Supercapacitor with a specific capacitance of 564.2 F g-1 (at 5 mVs-1) and 559.1 F g-1 (at 0.9 Ag-1), which is 3.1-fold higher than undoped OMC (179.7 F g-1). Be sides, GCD profiles reveal the energy density of 49.6 Wh kg-1 and power density of 359.9 W kg-1, which confirms the potential of the material in the fast-charge-discharge processes. Mechanistic studies validate the fact that synergistic redox interactions between Cu and Ni species facilitate the separation of electrons and holes, the production of reactive oxygen species (ROS), and the enhanced photocatalytic activity. These findings make OMC/CuO/NiO a second-generation dual functional material in the form of sustainable wastewater treatment and superior energy storage technologies.Item Correlative analysis of electrical-structural properties of 60B2O3.15ZnO. xLi2O.(25-x)Bi2O3 glass system(2026) K. Yadav, JaswantThe electrical conductivity of 60B2O3.15ZnO.xLi2O.(25-x)Bi2O3 glass system has been measured by complex impedance spectroscopy in the frequency range from 100 Hz to 5 MHz and temperature range 623-723 K with varying Li2O concentration. Experimentally observed data of ac conductivity is fitted with Jonscher’s power law, and conductivity parameters viz. crossover frequency (ωH), frequency exponent (s), dc conductivity (σdc), enthalpy of formation (Hf), and migration (Hm) of the Li+ ion have been estimated. Quantum Mechanical Electron tunnelling theory of conduction mechanism is found applicable in these glasses. At a given temperature, conductivity increases with Li2O content. The stretch parameter ‘β’ is observed to be temperature-dependent, and its value increases with a rise in Li2O content (β is 0.829 for x=10 and 0.928 for x=25 at 663 K), which signifies increased structural homogeneity and a smaller distribution of relaxation times. Relaxation time estimated from both electric modulus (τM") and impedance (τZ") decreases with an increase in Li2O content. With Li2O content, experimental values of dc (Edc) and ac (Ez) activation energies of the studied glass system follow similar behaviour as the total concentration of tetrahedral BO4 units (N4). An increase in the N4 fraction signifies a decrease in the activation energy for ionic conductivity.Item Chitosan, conducting polymer, and metal oxide nanocomposites: Mechanistic insights and sustainable approaches for water treatment(2026) Tandwal, AartiThe role of nanomaterials in sustaining life and different environmental challenges related to water pollution needs to be addressed.

So, transforming it into a more efficient and environmentally sustainable sector is essential., where Public Private Partnerships (PPPs) could play a crucial role. To address modifica tion at the policy level in India, the current study examined how transport carbon emissions are influenced by PPP investment along with urbanization, economic growth, FDI, trade openness and environmental technology innovations. The Quan tile Autoregressive Distributed Lag Model (QARDL) has been used for the period 1998Q1-2022Q4. The key results highlights that PPP investment in long run is insignificant in most of the quantiles but significant and negative in the quantiles ranging from 0.6 to 0.9 in short run reflecting the impact of PPP investment in high er quantiles. The Environmental Kuznets Curve (EKC) hypothesis has also been established in the data, whereas urbanization associated with the reduced transport sector emission in 0.2 to 0.9 quantiles. The study also found environmental technol ogy innovation associated with reduced transport emissions. Trade openness found insignificant in long run but significant and adverse effect on the environment in the short run. FDI have adverse effect on transport emission in the long run in all quantiles (0.1–0.9). Finally, policy proposals have been made for transport sector to reduce transport CO2 emissions in India.
