This work aimed to establish a numerical simulation of kerosene oil as a host Casson fluid flowing around a cylindrical shape with an applied magnetic field crossing through it, under constant wall temperature boundary conditions. Nanoparticles of zinc, aluminum, and titanium oxides were included to reinforce its thermal characteristics. The governing model was established based on the Tiwari and Das model. Graphical and numerical results for correlated physical quantities were gained through the Keller Box method, with the assistance of MATLAB software (9.2). The combined convection (λ>0 & λ<0), magnetic parameter (M>0), Casson parameter (β>0), and nanosolid volume fraction (0.1≤χ≤0.2) were the parameter ranges considered in this study. According to the current findings, the growth of mixed convection parameter or volume fraction of ultrafine particles contributes to boosting the rate of energy transport, skin friction, and velocity distribution. Zinc oxide–kerosene oil has the highest velocity and temperature, whatever the parameters influencing it.

A thorough investigation of MHD third‐grade differential‐type fluid flow over a heated stretching sheet is performed in this work. In particular, we analyze the film thinning process, when the thermal sensitive fluid parameters vary due to the effect of heat supplied to the stretching sheet. Starting with a two‐dimensional (2D) free surface boundary value problem of non‐Newtonian third‐grade fluid, we present a systematic derivation of a 1D transient thin‐film height equation using longwave analysis with respect to the small aspect ratio of the fluid domain. The derived model is used to study the impact of Newtonian and non‐Newtonian parameters with variable fluid properties on the thin film height. The model is discretized using an upwind discretization in space and implicit time integration to guarantee first‐order convergence. The model is analyzed thoroughly with the help of numeric computing software MATLAB. The existing findings for a Newtonian fluid are in excellent agreement with derived evidence. In comparison to Newtonian fluid, the study finds that the third‐grade parameter causes thinning under different parametric restrictions. Simulations on the coupling effect explain that, the film thickness can be reduced with a high Marangoni number for highly viscous fluids. Also, since the effect of the conductivity parameter can be reduced at a low Prandtl number, the fluid shows a thinning effect. The film thinning rate, on the other hand, is reduced by the magnetic field.

This study attempts to find out the curative effects of Allium siculum (A. siculum) on ethylene glycol (EG) induced kidney stone in male albino rats. Throughout this study, twenty-two male albino rats were taken and divided into four experimental groups. Group A is a control group, while the rest of the groups, namely group B, C, and D animals, received 1% EG in water for 14 days, then from day 15 to day 28, the treatment of EG stopped and group C and D animals from day 15 to day 28 received A. siculum (5g of dried powder in 100 ml water and 950 g standard diet) and cystone (2.5 tablets in water and standard diet) respectively. Serum uric acid, creatinine, urea, lipid profile measurements, and glucose were evaluated besides the kidneys' weight and body weight gain. Allium siculum and cystone treatments indicated a significant reduction in serum uric acid, creatinine, urea, glucose, very low-density lipoprotein, and triglyceride compared to EG-treated rats. The kidneys' weight and body weight gains significantly increased in group B compared with A, C, and D. In conclusion: A. siculum has curative effects on ethylene glycol induced kidney stone which resembled the cystone drug.
