Effect of Indium-Manganese (In-Mn) substitution on the structural electrical and dielectric properties of Ca0.5-x Ba0.5InxMnyFe12-yO19 (x = 0.00–0.10; y= 0.00–1.00) hexaferrites prepared by sol–gel auto combustion method was reported. As-synthesized samples were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrical and dielectric properties (resistivity and conductivity). The X-ray diffraction analysis confirmed the formation of M-type hexaferrite structure. A slight enhancement was found in the in-plane lattice constant a, while the lattice constant c was suppressed with the increasing concentration of In and Mn. The results of SEM images show that the grain size decreases with increase of In-Mn substitution from 10μm to 1μm. The increased dielectric properties and fine particle sizes are useful for many applications, such as cores of inductors, transformers, isolators and magnetic memory devices.

This article has explored the significance of artificial intelligence in business management and accounting over a period of 15 years from “2008 to 2022”. Artificial Intelligence is an emerging field of study for students and it is playing a pivotal role in the courses of business management and accounting. This article guides the students in using new innovations, techniques, methods, software’s etc. which are extremely helpful for our daily tasks. A scientometric approach is used to analyse the statistical-historical study of Artificial Intelligence in the field of business and accounting. The data is taken from the renowned and important data base “Scopus”. A study sample comprises 1608 documents covers the field of Business management and Accounting. Secondary documents were 440,652 with the keyword “Artificial Intelligence”. To find out the quality results, this study uses different statistical software’s like R-tool, R-Package, Bibliometrix, VOSviewer, and Biblioshiny. The findings show the result of top countries that have worked on artificial intelligence. USA has the top rank in all over the world in research work with the publication of 88,679. USA, China, UK, India and Germany are the top five most prominent and struggling countries that have worked on the keyword “artificial intelligence” respectively.

Aims: This study was aimed to screen indigenous medicinal plants for their antibacterial potential against methicillinresistant Staphylococcus aureus (MRSA). Methodology and results: Three indigenous plants (Nigella sativa, Zingiber officinale and Calotropis procera) and thymoquinone were screened for antibacterial activity against MRSA, isolated from septic wounds of patients admitted to Mayo Hospital Lahore, Pakistan. Isolated bacteria were screened for methicillin and cefoxitin resistance by the Kirby-Bauer method, followed by mecA gene-specific polymerase chain reaction (PCR). Confirmed MRSA was processed for antibacterial activity of plant extracts and thymoquinone followed by cytotoxicity assay of plant extract having least minimum inhibitory concentration (MIC) value. Out of total samples (n=100), S. aureus (29%), MRSA (26%) and vancomycin-resistant S. aureus (VRSA) (21.7%) isolates were recovered based on morphology, biochemical profile and antibiotic susceptibility testing. Nigella sativa showed the highest antibacterial activity (10.06 ± 6.53 mm) against MRSA followed by Z. officinale (4.06 ± 3.72 mm) and C. procera (3.65 ± 3.33 mm) in comparison to standard thymoquinone (17.93 ± 10.14 mm). The least MIC value recorded was for Z. officinale at 36.89 ± 3.75 µg/mL. Zingiber officinale was the most effective antibacterial agent, followed by N. sativa and C. procera and non-toxic for eukaryotic cells at all tested concentrations (1500 μg/mL to 2.92 μg/mL). Conclusion, significance and impact of study: It was concluded that Z. officinale may be used as an effective alternative for treating septic wound infection in local or topical preparations. As pathogenic S. aureus is becoming lifethreatening among antibiotic-resistant bacteria and traditional plants are in used for centuries to treat septic wound infections.
