In recent decades, evidence has continuously mounted regarding the myriad adverse health effects that environmental exposures exert on human health, yet little attention has been given to skeletal muscle-related outcomes. With its important metabolic, hormonal, and functional properties, skeletal muscle exerts a critical effect on human health and quality of life. The aim of this review was to survey the literature regarding potential impacts of environmental exposures on skeletal muscle health. The focus was on 10 substances atop the Agency for Toxic Substances and Disease Registry’s Substance Priority List including arsenic, lead, mercury, vinyl chloride, polychlorinated biphenyls, benzene, cadmium, benzo(a)pyrene, polycyclic aromatic hydrocarbons, and benzo(b)fluoranthene. In addition, per- and poly-fluoroalkyl compounds were included due to an increasing interest in the field of toxicology. Cell, animal, human, and population studies were all examined to determine toxicant effects on skeletal muscle, though the literature is scarce for many individual agents. Some commonalities, such as effects on mitochondrial function and sexually dimorphic consequences, were observed across compounds. Evidence indicates the need for further investigation of this important topic, with an emphasis on longitudinal large-scale population studies, and investigations which synthesize population and mechanistic research to interrogate causality.

Masculinities are social and cultural attributes, roles and performances typically associated with being men. Through ethnography, this article explores the complicated position of soft masculinity in mizo cultural space and nationalist discourse. It looks at tlawmngaihna ( mizo code of conduct) performances as hierarchies that are gendered and explains why men’s tlawmngaihna are considered to be more visible and valuable. Using hegemonic masculinity theory, this article argues that mizo nationalism is masculinised which is fuelled by homophobia and anti-femininity. Ultimately, it explains the complexity of soft mizo masculinity’s position and how they are involved but are non-visible in mi zo cultural space.

Gandhamardan has a rich heritage of floristic diversity with undocumented medicinal plants, called Anukta Dravya having immense pharmacological values. Among them, Pittosporum napaulense (DC.) Rehder & E. H. Wilson is an important medicinal plant with widespread pharmacological importance. The antioxidant potential, antibacterial and antibiofilm activities of P. napaulense (DC.) were evaluated. The ethanolic extract showed the highest share of phenolic and flavonoid contents responsible for DPPH and ABTS radical scavenging activity with an IC50 of 5.58 and 5.28 µg/ml, respectively. In addition, the extracts also showed antibacterial and antibiofilm properties against multidrug-resistant bacterial strains, Staphylococcus aureus and Shigella sp. The biological activities of P. napaulense (DC.) bark could be attributed to the presence of phytoconstituents such as Malabaricone C, Borapetoside B, Kanzonol R. as evident from UPLC-Q-TOF-MS analysis. Based on the bioactivities; this plant could be explored for the development of potential therapeutic drug candidates against severe bacterial diseases.

An adaptive neuro-fuzzy inference system (ANFIS) combines artificial neural networks (ANNs) with a Fuzzy Inference System (FIS) to predict the first three natural frequencies of basalt/carbon fiber (CF)-reinforced hybrid laminated composite face layers and Polyethylene Terephthalate (PET) foam-core skew sandwich plates. The ANFIS models are trained on large datasets, with accuracy validated through statistical methods. Elastic properties of the face layers and PET foam core are measured via uniaxial tensile and compression testing. Experimental modal analysis and numerical simulations in ABAQUS demonstrate that natural frequencies increase with skew angle and core thickness, but decrease with aspect ratios and fiber angles.

Composite double-leaf structures are widely used in aerospace and automotive components due to their low weight and high strength to weight ratio. During service, these structures are subjected to dynamic mechanical excitations and elevated temperature, which pose significant challenges to structural integrity, operational safety and acoustic insulation. Hence, the vibroacoustic energy transmission behavior of composite double-leaf structures in a thermal environment is investigated in the present research work. A coupled numerical framework is developed by integrating a non-linear strain-based finite element (FE) method with a direct boundary element (BE) approach for conducting the vibroacoustic analysis. Results indicate that the frequency shifts of structural panels due to thermal softening reach approximately 30–50% in different configurations, which enhances structural-acoustic coupling and thereby increases radiated sound energy by up to about 23% in certain cases. Furthermore, the incorporation of structural stiffeners on Panel I is shown to be an effective mitigation strategy, resulting in a reduction in radiated sound power of approximately 22% for unidirectional stiffener and up to 31% for bidirectional stiffener arrangements. In general, symmetric laminate configurations are found to provide better acoustic insulation. Moreover, symmetric cross-ply laminates show attenuated vibroacoustic response in the mid-frequency range (400–600 Hz).

This article intents to study the SH wave propagation in nano-structure solid composite having piezoelectric plate laying over elastic substrate. The piezoelectric layer is superimposed with viscous liquid. The constitutive equations involve the higher-order stress tensor that gives rise to micro-inertia effect. Dispersion and attenuation curve have been plotted to unravel the peculiarities of various parameters viz. , thickness of piezoelectric plate at nanoscale level, dimensionless heterogeneity of elastic half-space, gradient coefficient and micro-inertia component of both the piezoelectric and elastic medium, and viscosity coefficient of liquid layer. Also, the impact of plate thickness on the electromechanical coupling parameter is depicted. To highlight the differences between the dispersion relations of open and short circuit cases, curves have been plotted. Remarkable impact of these parameters has been observed and discussed extensively by using numerical example. This study finds its application in analyzing and designing of nanoscaled SAW devices most suitable for liquid sensing.

Stress analysis of contact zones in bearing is of paramount importance as it plays a crucial role in deciding its performance and durability. Operational issues such as misalignment, improper loading and lubrication failure often lead to surface defects such as spalling, which accelerate premature failure. This study analyses an NU356 cylindrical roller bearing to investigate spall-induced stress concentrations. The analysis demonstrates that changing the angular orientation of the notch significantly influences stress distribution in the bearing, with orientations near the vertical axis (0°–10°). Stress analysis is performed through Finite Element Analysis for notch locations ranging from 10° to 90°, considering the bearing’s horizontal and vertical symmetry. Numerical predictions are experimentally validated using photoelastic stress analysis, confirming the accuracy of the simulation approach and supporting improved bearing failure assessment.

This article presents a comprehensive analysis of doubly curved laminated composite shells, focusing on both static and free vibration behaviors. This study presents a novel finite element framework in Cartesian coordinates, formulated using the Carrera Unified Formulation (CUF), for the analysis of thin doubly curved laminated composite shells. The proposed method effectively accommodates complex boundary and loading conditions through a computationally efficient Equivalent Single Layer framework. By systematically investigating a wide range of geometric configurations and shear deformation orders, the study reveals structural response characteristics that are insufficiently characterized in the current literature. The study utilizes the Equivalent Single Layer approach within the framework of the CUF to evaluate displacement fields, stress distributions, and natural frequencies. In the static analysis, displacement and stress patterns are examined under specified loading conditions, while the free vibration analysis focuses on identifying the first two natural frequency modes. A major advantage of CUF is its capability to model thin to moderately thick doubly curved laminated composite shells by incorporating curvature effects into displacement and strain fields. Its flexibility, achieved through user-defined expansion orders or deformation theories, enables an accurate representation of structural behavior. The results show excellent agreement with benchmark solutions from the available literature, validating the proposed methodology. The computational efficiency of the proposed formulation is further demonstrated through CPU-time and GDOF comparisons with a Murakami zig-zag model. This study provides valuable insights into the mechanical response of doubly curved laminated composites under various practical boundary and loading conditions, examining the influence of geometric parameters and thereby contributing to the effective design and analysis of advanced structural systems.

This research paper utilizes second-order gradient electroelasticity theory to develop a theoretical model of Love-type surface wave transference considering strain and inertia gradient effects in a Kelvin–Voigt type viscoelastic lossy polymer-coated piezoelectric substrate. Non-classical constitutive equations derived from variational principles are used to obtain electromechanically coupled field equations. Using proper analytical techniques and non-classical boundary conditions, dispersion relations for electrically open and short cases are derived. Numerical example has been provided and graphs have been plotted to visualize the dependency of velocity and attenuation traits of Love-type waves on considered strain gradient, inertia gradient, and other relevant parameters like viscosity and layer width. It has been observed that the phase velocity of the fundamental mode of surface wave is highly affected by strain gradient elasticity and micro-inertia and high gradient elasticity helps to achieve high phase velocity. The investigation can provide proper guidelines to optimize biological or chemical surface acoustic wave (SAW) sensors with nanocoating. HighlightsNanoscale strain gradient elasticity and micro-inertia effect are considered in the shear wave propagation model. Non-conductive Kelvin–Voigt model-based viscoelasticity is assumed for coating polymer. Attenuation is also characterized along with phase velocity on a logarithmic scale. Dispersion characteristics are investigated for electrically open and short boundary types.
