Influence of SERPINA1 Gene Polymorphisms on Anemia and Chronic Obstructive Pulmonary Disease
Background. Anemia is one of the predominant hematological conditions, whereas chronic obstructive pulmonary disease (COPD) is a predominant respiratory disease. These two diseases were found to be interlinked, but the physiological pathways are still unclear. Aim. The current study has been aimed at analysing the genetic interrelationship between anemia and COPD in accordance with different altitudes. Methodology. The genetic analysis was performed in the SERPINA1 gene of anemia, COPD, and healthy individuals for the analysis of single nucleotide polymorphism at rs28949274 and rs17580 locations. Result and Discussion. The single nucleotide polymorphism at the locations rs28949274 and rs17580 was present in both anemic and COPD patients. The COPD patients were more prone to mutations (63% had rs28949274, and 11% had rs17580 polymorphisms) than the anemic patients (40% had rs28949274, and 1% had rs17580 polymorphisms). On the basis of altitude, high-altitude individuals were found to be more susceptible to both the polymorphisms. Conclusion. Based on the current findings, we suggest that the SERPINA1 gene has a positive correlation with anemia as well as COPD, and the increase in altitude also influences the diseased conditions in a positive manner. 2022, SAGE Publications Ltd.

Influence of Short Glass Fibre Reinforcement on Mechanical Properties of 3D Printed ABS-Based Polymer Composites
Fused deposition modelling; Polymer composite; Short glass fibre; Twin screw extrusion
One of the most promising and widely used additive manufacturing technologies, fused deposition modelling (FDM), is based on material extrusion and is most commonly used for producing thermoplastic parts for functional applications with the objectives of low cost, minimal waste and ease of material conversion. Considering that pure thermoplastic materials have a significantly poor mechanical performance, it is necessary to enhance the mechanical properties of thermoplastic parts generated using FDM technology. One of the conceivable techniques is to incorporate reinforcing materials such as short glass fibre (SGF) into the thermoplastic matrix in order to produce a polymer composite that can be used in engineering applications, such as structural applications. The morphological and mechanical properties of SGF (short glass fibre) reinforced ABS- (Acrylonitrile Butadiene Styrene) based polymer composites created via the method of FDM (fused deposition modelling) were investigated in this work. Properties were evaluated at three different weight percentages (0, 15 and 30 wt%). The composite filaments were developed using the process of twin screw extrusion. The comparison was made between ABS + SGF (short glass fibre) composites and pure ABS of mechanical properties that include surface roughness, tensile strength and low-velocity impact. The tests were carried out to analyze the properties as per ASTM standards. It has been found that the impact strength and tensile strength show an improvement in glass fibre inclusion; moreover, alongside the direction of build, the surface roughness had been reduced. The studies also focused on studying the dispersion characters of SGF in ABS matrix and its impact on the properties. Strength and modulus of SGF reinforced ABS composite has been significantly improved along with reduction of ductility. A 57% increase in tensile strength has been noted for 30 wt% addition of SGF to ABS in comparison to pure ABS. It was also interesting to note the reduction in surface roughness with every incremental addition of SGF to ABS. A 40% reduction in surface roughness has been observed with a 30 wt% addition of SGF to ABS in comparison to pure ABS. 2022 by the authors.Licensee MDPI, Basel, Switzerland.

Influence of shot peening on microstructure and electrochemical behavior of al-Cu alloy; [Influence du grenaillage sur la microstructure et le comportement.]
Al-Cu alloy; Corrosion; Microstructure evolution; Precipitation behavior; Shot peening
The current study explores the effects of shot peening on the microstructural evolution and corrosion behavior of precipitation-hardened Al-Cu alloy. Microstructural analysis revealed significant grain size reduction from 100 m to 6.5 m, and this process improves grain boundary density, reduces precipitate size from 2 m to 0.5 m, and ensures a uniform elemental distribution, effectively mitigating galvanic corrosion risks. Energy-dispersive spectroscopy (EDS) confirms the homogenisation of alloying elements. At the same time, X-ray diffraction (XRD) analysis highlights crystallographic modifications, including refined crystallite size, redistributed secondary phases, and compressive residual stresses, contributing to enhanced strength and fatigue resistance. Corrosion behavior studies reveal a dramatic reduction in weight loss from 0.09 mg to 0.03 mg and a corrosion rate decrease from 3.5 10?3 mpy to 1.5 10?3 mpy, along with a noble shift in corrosion potential from ?1150 mV to ?775 mV. As observed in optical microstructures, grain refinement, residual stress introduction, and uniform surface characteristics lead to a significant shift from severe to mild corrosion attacks. Impedance analysis demonstrated improved corrosion resistance in the shot-peened alloy, evidenced by higher charge transfer resistance (Rct) and lower double-layer capacitance (Cdl). 2025 Canadian Institute of Mining, Metallurgy and Petroleum.

Influence of Sinusoidal and Non-Sinusoidal Two-Frequency Gravity Modulation in Viscoelastic Fluids Driven by Triple Diffusivity
gravity modulation; nusselt number; sherwood number; triple diffusive convection; viscoelastic fluid
This study focuses on understanding the system's response to gravity modulation with two frequency components, characterized by both sinusoidal (sine wave) and non-sinusoidal (square, triangular, and sawtooth) waveforms, on three-component convection, considering a viscoelastic fluid modelled using an Oldroyd-B fluid. We apply the Venezian approach to evaluate the Rayleigh number, its corrected form, and the wave number by deriving a five-mode Lorenz model to investigate the onset of convection. A nonlinear analysis is conducted to investigate the dynamics of heat and mass transfer by solving an extended eight-mode Lorenz model, capturing higher order interactions. The onset of convection and the transport properties were observed to be influenced by combinations of sinusoidal and non-sinusoidal waveforms. This study optimizes convection-driven systems subjected to external periodic forcing by offering a more comprehensive understanding of convective instabilities in viscoelastic fluids. 2025 Wiley Periodicals LLC.

Influence of Social Media Marketing on Student Decision-Making in Higher Education
This present study looks into the role of social media marketing as an important tool that helps organizations achieve their goals, bearing in mind the rapid spread in the modern digital world. Higher education institutions, such as colleges and universities, are making use of these social media channels: Facebook, Instagram, LinkedIn, and YouTube to share information regarding their academic programs, campus life, and even success stories. These websites have helped institutions to increase their access and engagement at the grass-roots level. It, thus, has also become an excellent tool to enroll prospective students. College or university search methods have undergone many significant changes in the present day. Over the centuries, students relied mainly on familial and social connections along with printed sources of information, to guide choices. Today, however, they increasingly use social media sites to research available choices, read reviews, watch multimedia and communicate with educational institutions. 2026 by IGI Global Scientific Publishing.

Influence of Solvent Environment on the Photophysical Properties of Maleamic Acid and Maleimide Derivatives
B3LYP; Dipole moment; Solutesolvent interactions; Solvatochromic shift method; Stokes shift
Absorption and fluorescence spectra of novel maleamic acid (E)-4-oxo-4-(4-((2-oxooxazolidin-4-yl)methyl)phenylamino)but-2-enoic acid (OMPBA) and its maleimide derivative 1-(4-((2-oxooxazolidin-4-yl)methyl)phenyl)-1H-pyrrole-2,5-dione (OMPPD) were recorded in a series of eighteen solvents of increasing polarity at room temperature (25C). A large Stokes shift indicates a bathochromic fluorescence band shift for both molecules. The photoluminescence properties and intramolecular charge transfer (ICT) behavior of OMPBA and OMPPD were analyzed. In the case of OMPPD, ICT contributes to a larger extent towards positive solvatochromism compared to OMPBA. Ground-state and singlet excited-state dipole moments of OMPBA and OMPPD were calculated using solvatochromic methods proposed by Bilot and Kawski, Lippert and Mataga, Bakhshiev, Kawskii and Chamma and Viallet, and also Reichardt. The ground state dipole moment was found to be larger than for the singlet excited state for both molecules. Optimized geometry and HOMOLUMO energies of OMPBA and OMPPD have been determined by DFT and TDDFT/B3LYP/6-311G (d, p). The HOMOLUMO energy gap was calculated from cyclic voltammetry and compared with theoretical values with good agreement. GCRD parameters such as ionization potential (IP), electron affinity (EA), electronegativity ?, chemical potential (?), chemical hardness (?), chemical softness (s) and electrophilicity (?) were calculated for OMPBA and OMPPD. 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Influence of symmetric/asymmetric boundaries on axisymmetric convection in a cylindrical enclosure in the presence of a weak vertical throughflow
Axisymmetric convection; Chaos; Cylindrical enclosure; Newtonian-Boussinesq fluid; RayleighBard convection; Throughflow
The linear and nonlinear stability of axisymmetric convection of a viscous fluid in a cylindrical enclosure heated from below is investigated for various radius to height ratios. A weak vertical throughflow is imposed in a gravity-aligned or a gravity-opposing manner. Symmetric and asymmetric boundaries of free-free, rigid-rigid and rigid-free types are considered for lower and upper boundaries with isothermal temperature boundary condition. The side-walls are assumed to be rigid and adiabatic. A convergent Maclaurin series representation is considered for the finding of axial trial eigenfunctions. In order to corroborate the results of the present study with those of a previous investigation, the critical Rayleigh number and the number of radial rolls manifesting for any given aspect ratio are determined in the case of no throughflow and an exact match is found. Further, the influence of boundaries and the effect of throughflow on chaotic and periodic regimes of motion are studied with the help of a time series solution and the largest Lyapunov exponent as indicators of chaos. The novelty of the present study is the use of a Maclaurin series representation for the eigenfunctions of the linear problem and using the same in determining the solution with the convective mode. 2023 Elsevier B.V.

Influence of Synthesis Temperature on the Structural, Morphological and Optical Properties of MoO3 Nanorods
Luminescence; Phosphor; Refractive index; Wide bandgap
Molybdenum trioxide nanomaterials have attained notable attention in the recent past and are used in various optoelectronic and biomedical applications. Here blue and purple blue light emitting MoO3 nanophosphors were synthesized using the simple hydrothermal method at three different temperatures 100C, 150C, and 200C. Structural characterization using XRD along with Raman spectroscopy confirms the formation of a highly stable orthorhombic phase. Micro strain effects have been analyzed by employing the Williamson-Hall method using a uniform deformation model. Nanorod like morphology was obtained from FESEM. Optical analysis, using Tauc plot shows a decreasing trend in bandgap value with increasing temperature. Emission peaks in the photoluminescence spectrum are associated with the transition between the sub-bands of the Mo5+ defect state. From CIE coordinates it is confirmed that the characteristic light from the samples is blue and purple-blue. Being an excellent blue and purple blue light emitting phosphor, MoO3 is a suitable material for future LED and fluorescence imaging applications.

Influence of Te doping on the dielectric and optical properties of InBi crystals grown by directional freezing
Crystals; Dielectric properties; Doping; Indium bismuthide; Optical properties; Phase transitions; Tellurium
Stoichiometric pure and tellurium (Te) doped indium bismuthide (InBi) were grown using the directional freezing technique in a fabricated furnace. The X-ray diffraction profiles identified the crystallinity and phase composition. The surface topographical features were observed by scanning electron microscopy and atomic force microscopy. The energy dispersive analysis by X-rays was performed to identify the atomic proportion of elements. Studies on the temperature dependence of dielectric constant (?), loss tangent (tan?), and AC conductivity (?ac) reveal the existence of a ferroelectric phase transition in the doped material at 403 K. When InBi is doped with tellurium (4.04 at%), a band gap of 0.20 eV can be achieved, and this is confirmed using Fourier transform infrared studies. The results thus show the conversion of semimetallic InBi to a semiconductor with the optical properties suitable for use in infrared detectors. 2014 University of Science and Technology Beijing and Springer-Verlag Berlin Heidelberg.

Influence of Two-Frequency Rotational Modulation on the Dynamics of the Rayleigh-Bard Convection in Water-Based Nanoliquids with Either AA7072 or AA7075 Nanoparticles
Aluminum alloy; nanoliquid; Rayleigh-Bard convection; rotation modulation; two-frequency modulation
The effect of time-periodic two-frequency rotation modulation on Rayleigh-Bard convection in water with either AA7072 or AA7075 nanoparticles is investigated. The single-phase description of the Khanafer-Vafai-Lightstone model is used for modeling the nanoliquids. An asymptotic expansion procedure is adopted in the case of the linear stability to obtain the correction (due to modulation) to the Rayleigh number at marginal stability of unmodulated convection. A nonlinear regime of convection is considered with a nonautonomous generalized Lorenz model as the governing equation. The method of multiscales is then employed to obtain the coupled nonautonomous Ginzburg-Landau equations with cubic nonlinearity from the Lorenz model. These equations are presented in the phase-amplitude form and the amplitude is used to quantify the heat transport. The modulation amplitude is considered to be small (of order less than unity) and moderate frequencies of modulation are considered. We found that there is a threshold frequency beyond which the system behavior reverses. At frequencies below the threshold, the mean Nusselt number increases with an increase in the amplitude of modulation while an opposite influence is seen for values above the threshold. Such a behavior is a consequence of what is analogously seen in the case of the critical Rayleigh number. The influence of two-frequency modulation is more pronounced on the results of the linear and nonlinear regimes compared to that of the single-frequency one. The heat transport is enhanced due to the presence of dilute concentration of suspended nanoparticles (either AA7072 or AA7075 nanoalloys) in water. The influence of nanoparticles is to modify the threshold values generating chaos but it does not qualitatively alter the dynamical behavior of the system. The plots of Lyapunov exponents reveal that there is no possibility of hyper-chaos in the generalized Lorenz model when there is a rotational modulation. 2024 World Scientific Publishing Company.
