PoliticsPolitics is the set of activities that are associated with the governance of a country, state or an area. It involves making decisions that apply to groups of members. It refers to achieving and exercising positions of governance—organized control over a human community, particularly a state.The academic study focusing on just politics, which is therefore more targeted than general political science, is sometimes referred to as politology (not to be confused with politicology, a synonym for political science). In modern nation-states, people often form political parties to represent their ideas. Members of a party often agree to take the same position on many issues and agree to support the same changes to law and the same leaders.By: Vijaya Super adminWednesday, May 12, 2021AGRI-FOOD SYSTEMS+3

chemistry grantsAbstract A new permanently positively charged stable isotope labeling (SIL) agent pair, 4-(((2,5-dioxopyrrolidin-1-yl)oxy)carbonyl)-N,N,N-trimethylbenzenaminium iodide(DPTBA) and its deuterated counterpart d3-DPTBA, was designed and synthesized. The SIL agents were applied to the liquid chromatography–tandem mass spectrometry analysis of alkylphenols. Light labeled standards and heavy labeled samples were mixed and analyzed simultaneously. Matrix effect which mainly occurred during the ionization process was minimized because of the identical ionization processes between samples and standards. Meanwhile, derivatization made alkylphenols be positively charged, and thus the sensitivity was enhanced. The limits of detection were in the range of 1.5–1.8 ng/L, and the limits of quantitation were in the range of 4.8–6.1 ng/L. The developed method was applied to analyze alkylphenols migrated from plastics to edible oils. The recoveries for all analytes were in the range of 88.6–95.3%, while the matrix effects for all analytes were in the range of 96.2–99.6%.By: AmeliyaWednesday, May 12, 2021HEALTH AND NUTRITION+2

NatureThe onion, known as the bulb onion or common onion, is not only a key ingredient in many tasty and healthy vegetarian meals but also many traditional medicines. Nine new flavonoids [cepaflavas A, B (5, 6), cepadials A–D (7–9 and 14), and cepabiflas A–C (10–12)] and six known compounds (1–4, 13, 15) were obtained from the outer skins of Allium cepa L. Among them, compounds 5, 6, and 9 might be artificial products formed during extraction and isolation. New compounds were structurally elucidated using various spectroscopy/spectrometry techniques, including NMR and HRMS, and computational methods.
