Fermatean fuzzy Einstein aggregation operators-based MULTIMOORA method for electric vehicle charging station selection

Abstract: The optimal location of electric vehicle charging station (EVCS) will promote the rapid development of the electric vehicle (EV) industry. Generally, EVCS location selection is treated as complex uncertain multi-criteria decision-making (MCDM) problem because of the existence of many quantitative and qualitative influencing factors. Moreover, uncertainty is usually occurred in EVCS location selection problem and Fermatean fuzzy set (FFS), as an expansion of Pythagorean fuzzy set, can effectively handle the ambiguity by reducing human intervention. Thus, the aim of the current study is to design an integrated decision making method for solving multi-criteria EVCS location selection problem under FFS context. This method is based on multi-objective optimization based on the ratio analysis with the full multiplicative form (MULTIMOORA) approach, maximizing deviation method and Einstein aggregation operators within Fermatean fuzzy environment. At the same time, the criteria weights are determined through the maximizing deviation method. For this, we introduce a divergence measure for FFSs. To aggregate the decision information, we propose some novel Einstein operations for FFS. In light of these operational laws, we further suggest some Fermatean fuzzy Einstein aggregation operators and their enviable characteristics. To illustrate the potentiality and usefulness of the present methodology, we carry out an illustrative study of EVCS location selection problem with FFS setting. Comparing the present MULTIMOORA framework with the extant methods confirms the strength of the obtained outcomes. The findings conclude that the introduced method is more useful and well-consistent with extant methods.

Wave propagation in thermally conducting linear fibre-reinforced composite materials

Abstract: The propagation of plane waves in a fibre-reinforced, anisotropic, generalized thermoelastic media is discussed. The governing equations in x–y plane are solved to obtain a cubic equation in phase velocity. Three coupled waves, namely quasi-P, quasi-SV and quasi-thermal waves are shown to exist. The propagation of Rayleigh waves in stress free thermally insulated and transversely isotropic fibre-reinforced thermoelastic solid half-space is also investigated. The frequency equation is obtained for these waves. The velocities of the plane waves are shown graphically with the angle of propagation. The numerical results are also compared to those without thermal disturbances and anisotropy parameters.

Endemic fluorosis in Rajasthan

Abstract: Chronic fluoride (F) toxicity in the form of osteo-dental fluorosis was observed in both sexes of children and adults from ten villages viz., Bhavanpura, Dovada, Genhuwara, Gokulpura, Hathai, Kahela, Mandav, Nalwara, Pratappura and Samota located in the vicinity of alive F mines of Dungarpur district (Rajasthan) where F concentration in drinking waters varied from 1.2 to 8.9 ppm. At 1.7 and 6.1 mean F concentrations, 70.6% and 100.0% of children ( 21 years) were showing evidence of skeletal fluorosis, respectively. Although, skeletal fluorosis was also found in children with low prevalence (5.2%) but at high F concentration (4.8 ppm). The prevalence of skeletal fluorosis was relatively higher in males and increased with higher F level and age. Deformities such as crippling, kyphosis, invalidism and genu-varum were observed frequently in higher age group subjects (> 48 years) at a F concentration of 3.3 ppm. None of fluorotic individuals revealed evidence of genu-valgum syndrome and goitre (thyroidism). Radiological findings of other deformities in fluorotic subjects were also found. The distribution of F and endemic fluorosis in different districts of Rajasthan state have also been reviewed.

Hepatoprotective Activity of Ficus carica Leaf Extract on Rifampicin-Induced Hepatic Damage in Rats.

Abstract: Shade dried leaves of Ficus carica were extracted using petroleum ether (60-80°) and tested for antihepatotoxic activity on rats treated with 50 mg/kg of rifampicin orally. The parameters assessed were serum levels of glutamic oxaloacetate transaminase, glutamic pyruvic transaminase, bilirubin and histological changes in liver. Liver weights and pentobarbitione sleeping time as a functional parameter were also monitored. There was significant reversal of biochemical, histological and functional changes induced by rifampicin treatment in rats by petroleum ether extract treatment, indicating promising hepatoprotective activity.
