Isotenulin, C17H22O5, is a sesquiterpene lactone isolated from sneezeweed Helenium amarum.It crystallizes with two independent molecules in the Brushes asymmetric unit.In each molecule, two five-membered rings (cyclopentenone and lactone) are trans-fused to the central seven-membered ring.The five-membered rings each adopt envelope conformations.Th
Oil projects in the province of Basrah are Brushes widely spread and remarkably increasing as they are considered to be of a significant impact on the environment of this region in elements of air, water and soil.This is due to the presence of toxic elements in the air as a result of fuel, or waste thrown into the water.So, this research addresses
We present a population-level view of volatile gas species (H _2 , He, H _2 O, O _2 , CO, CO _2 , CH _4 ) distribution during the sub-Neptune to rocky planet transition, revealing in detail the dynamic nature of small planet atmospheric compositions.Our novel model couples the atmospheric escape model IsoFATE with the magma ocean-atmosphere 7 equil
The aim of this research is to distinguish business risks that affect natural gas trading companies operating in the liberalized natural gas market and to assess them according to the potential impact on the aforementioned gas trading companies.To achieve this, a study of international scientific literature and empirical research was conducted, as
This research presents a groundbreaking approach in virus-related research, addressing challenges in electron microscopy (EM).This imaging technique has been crucial in exploring virus structures; however, traditional methods involve complex sample preparations and the risk of contamination.Herein, we introduce Jigsaw Puzzle an approach that overco
