Abstract

A thin Nb target on a Pb backing was fabricated using the rolling technique. In the present work, the characterization of the sample has been carried out using various techniques to study the surface morphology, crystallography, elemental analysis, thickness and electrical conductivity useful for the intended use of the target prepared. The thin Nb target was analyzed using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and Rutherford back-scattering spectroscopy (RBS) techniques. The uniform and smooth surface of the sample was confirmed by SEM imaging. The presence of oxygen in the EDS spectra and peaks corresponding to crystal planes of PbO2 in the XRD spectrum confirms the oxidation of Pb foil. The XRD spectrum shows clear peaks corresponding to (011), (002), (112) crystal planes of pure Nb. The thickness of the thin Nb foil measured using the RBS techniques was found to be 0.8 mg/cm2. The current(I)-voltage(V) curve (relationship between the current flowing through an electronic device and the applied voltage across its terminals) at room temperature for the Pb and Nb/Pb foils was plotted and showed linear relationship between applied voltage and current flowing through the target foil. The measured electrical conductivity indicates an enhancement of 35.9 % for Nb/Pb foil relative to the conductivity measured for the Pb foil.

Abstract

Abstract Background Domestic violence during pregnancy is especially concerning due to its significant detrimental impact on a woman’s health and that of her unborn child. The study aims to evaluate the effects of a behavioural intervention package (BIP) delivered during pregnancy on the quality of life (QOL), domestic violence (DV), and reproductive and child health (RCH) of women experiencing DV. Methods A randomised controlled trial was conducted on 211 pregnant women recruited between 18 and 20 weeks of pregnancy and randomly assigned to one of two groups: intervention (n = 105) or control (n = 106). The intervention group received BIP and standard care, while the control group received only standard care for 28 weeks. Study tools included socio-demographic variables, a short-form health survey, an abuse assessment screening tool, and an RCH checklist. The tools were completed once before the intervention and again at 6 weeks postnatal. The tools and their subscales were compared pre- and post-intervention using a paired t-test, or Wilcoxon signed test as appropriate to estimate the effect size at baseline and post-intervention. Results Post-intervention, the QOL scores were found to be significant, with a positive effect favouring the intervention as compared to the control group. The BIP intervention, which was found to be significantly effective (P ≤ 0.001) in reducing DV for pregnant women experiencing DV, was higher in the intervention group than in the control group. Conclusion The BIP may be an appropriate method for treating pregnant women experiencing DV from low socioeconomic strata who attend public hospitals in India to improve their QOL. The approach may offer an intervention that healthcare institutions or other organizations in contact with women at risk of violence can implement. Trial registration Indian Registry of Clinical Trials CTRI/2019/01/017009. Registered on 09/01/2019.
