Evaluation of total phenols and antibacterial activity of certain drug plants against some bacterial species

The present paper deals with antimicrobial activity of Glycyrrhiza glabra, Tinospora cordifolia, Tribulus terrestris, Thevetia peruviana, Adhatoda vasica, Vitex negungo, Apium graveolens and, Annona squamosa. It was studied against Bacillus cereus, Staphylococcus aureus, Salmonella typhy B (STB), Shigella dysenteriae using solvent (methanol and petroleum ether) extraction method. Methanol extract of all eight plants showed prominent inhibitory activity against S. dysenteriae and STB while G. glabra, V. negundo, and T. peruviana showed maximum zone of inhibition against four studied bacterial species. These results suggest that methanol extract is more effective than petroleum ether for the antimicrobial activity. Further total phenols were estimated and antibacterial activity of these plants in relation to total phenolic content is discussed

Installation, commissioning, and testing of the HB650 CM at PIP2IT

The Proton Improvement Plan-II (PIP-II) is a major upgrade to the Fermilab accelerator complex, featuring a new 800-MeV Superconducting Radio-Frequency (SRF) linear accelerator (LINAC) powering the accelerator complex to provide the world's most intense high-energy neutrino beam. This paper describes the conversion of the PIP-II Injector Test Facility (PIP2IT) cryogenic system into a test stand for PIP-II High-Beta 650 MHz (HB650) cryomodules at Fermilab's Cryomodule Test Facility (CMTF). A description of the associated mechanical, electrical, and controls modifications necessary for testing HB650 cryomodules are provided. The cooldown and warmup requirements, procedures and associated controls logic is described.Comment: 2023 Cryogenic Engineering Conference and International Cryogenic Materials Conference (CEC/ICMC
