Explicit scheme for solving variable-order time-fractional initial boundary value problems.

The creation of an explicit finite difference scheme with the express purpose of resolving initial boundary value issues with linear and semi-linear variable-order temporal fractional properties is presented in this study. The rationale behind the utilization of the Caputo derivative in this scheme stems from its known importance in fractional calculus, an area of study that has attracted significant interest in the mathematical sciences and physics. Because of its special capacity to accurately represent physical memory and inheritance, the Caputo derivative is a relevant and appropriate option for representing the fractional features present in the issues this study attempts to address. Moreover, a detailed Fourier analysis of the explicit finite difference scheme's stability is shown, demonstrating its conditional stability. Finally, certain numerical example solutions are reviewed and MATLAB-based graphic presentations are made.

Serum resistin and lipid profile in primigravida females with and without preeclampsia: An analytical cross-sectional study.

OBJECTIVE: To measure and compare the serum levels of resistin and lipid profile parameters in primigravida females with and without preeclampsia. Methods: The analytical cross-sectional study was conducted at the Department of Physiology and Cell Biology, University of Health Sciences, Lahore, Pakistan, from 2018 to 2020, and comprised primigravida females having gestational age 30-36 weeks. Those with preeclampsia constituted group 1, while normotensive females constituted group 2. All the participants were subjected to detailed history and general physical examination. Serum resistin levels were measured by enzymelinked immunosorbent assay, and lipid profile parameters were measured using the colorimetric method. Data was analysed using SPSS 20. RESULTS: Of the 80 women, 40(50%) were in group 1 with mean age 23.07±2.10 years and mean gestation age 33.45±2.30 weeks. There were 40(50%) women in group 2 with mean age 23.02±2.11 years and mean gestational age 34.45±1.75 weeks. Mean serum resistin was significantly higher in group 1 compared to group 2 (p<0.02). Mean levels of lipid parameters were significantly different between the groups (p˂0.05). Conclusion: Preeclampsia was found to be associated with higher levels of resistin and lipid parameters compared to normal pregnancy.
