In this manuscript a comparative study on Bi2O3/polystyrene and Bi2O3/PVDF composites has been executed via analysis of structural, bonding, surface morphology and dielectric response of composites for energy storage. The composites have been synthesized using solution cast method by varying concentrations of Bi2O3 (BO = 1 - 5 mw%) into polystyrene (PS) and polyvinylidene fluoride (PVDF) polymers respectively. X-ray diffraction confirms the generation of crystallinity, Fourier transform infrared (FT-IR) spectroscopy confirms bonding behavior and scanning electron microscopy (SEM) confirms uniform distribution of Bi2O3 (BO) in PS and PVDF polymers. Impedance spectroscopy has been employed for determination of dielectric response of the fabricated composites. The dielectric constant has been found to be increased as 1.4 times of pristine PS to BO5%PS95% composites and 1.8 times of pristine PVDF to BO5%PVDF95% composites respectively. These high dielectric composite electrodes are useful for flexible energy storage devices.

Objective: The main aim of the survey was to assess diabetes treatment-related myths prevalent in the Indian population and if COVID-19 pandemic improved their knowledge about diabetes. Results: The survey was completed by 309 participants;66% did not have diabetes. The responses of people with diabetes and those without diabetes were similar. Survey results of the total population showed that the majority believed that diabetes treatment should start early (92.6%);87.4% believed that the treatment should start within three months of diagnosis with modern medicines;67.3% of the participants felt that allopathic medicines for diabetes were safe, 69.6% believed that if started these medications continue lifelong, and 40.5% thought they damaged all major organs. Insulin was thought to be safe by 65% of the surveyed population;60.8% believed that if they started insulin, they would need it life-long;51.5% thought that insulin was started at the last stage of diabetes;and 58.6% believed that insulin caused kidney damage. A total of 58.6% believed that herbal medicines for diabetes were safer than allopathic;76.4% did not believe that the “diabetic cure” shown through television/newspapers was safe and effective;67.3% did not believe that ayurvedic medicines cured diabetes. Of the surveyed population, 67% felt that their knowledge about diabetes improved during the pandemic and 89.3% knew that PWDs have more serious problems with covid infection. Conclusions: Our survey shows that many diabetes treatment-related myths are prevalent in the Indian population even though the COVID-19 pandemic improved their knowledge about diabetes.

Bianchi type-I massive string cosmological model with magnetic field of barotropic perfect fluid distribution through the techniques used by Latelier and Stachel is investigated. To obtain the deterministic model of the universe, it is assumed that the universe is filled with barotropic perfect fluid distribution. The magnetic field is due to electric current produced Mong the x-axis with infinite electrical conduictivity. The behaviour of the model in the presence and absence of magnetic field together with other physical aspects is further discussed.

Abstract Aim: To evaluate the antifertility effect ofAlstonia scholaris bark extract in male rats. Methods: In male Wistar rats Alstonia scholaris bark extract was given by oral route at a dose of 200 mg/day for 60 days. The fertility and testicular function were assessed by mating tests, sperm motility, sperm concentration, biochemical indices and testicular cell population dynamics. Results: Oral feeding with the extract at a dose of 200 mg/day for the period of 60 days did not cause body weight loss, while the weights of testes, epididymides, seminal vesicle and ventral prostate were significantly reduced. The production of step-19 spermatids was reduced by 79.6% in treated rats. The population of preleptotene and pachytene spermatocytes were decreased by 61.9% and 60.1%, respectively. Spermatogonia and Sertoli cell population were also affected. The seminiferous tubule and Leydig cell nuclear area were reduced significantly (P<0.01) when compared to the controls. Reduced sperm count and motility resulted in a total suppression of fertility. A significant fall in the protein and sialic acid content of the testes, epididymides, seminal vesicle and ventral prostate as well as glycogen content of testes were also noticed. The fructose content in the seminal vesicle was lowered whereas the testicular cholesterol was elevated as compared with the controls. The following compounds were obtained from the extract with chromatographic separation over Si-gel column: α-amyrin, β-amyrin, lupiol acetate, venenative, rhazine and yohimbine. Conclusion: At the dose level employed, Alstonia scholaris bark extract has a significant antifertility effect in male rats; the primary site of action may be post meiotic germ cells (Step 19 spermatids).
