Abstract Background Metabolomics is a promising molecular tool for identifying novel etiological pathways leading to cancer.In an earlier prospective study among pre- and postmenopausal women not using exogenous hormones, we observed a higher risk of breast cancer associated with higher blood concentrations of one metabolite (acetylcarnitine) and a
Significant amounts of unconventional oil and gas resources have been discovered in the Yanchang Formation of Ordos Basin.Shale layers deposited in Chang 7 member (divided into Chang 7-2 submember (C7-2SM) and Chang 7-3 submember (C7-3SM) and Chang 9 member (C9M)) are the main source rocks.Based on the comparison of mineralogical and geochemical ch
Soil quality assessment research has progressively developed over four decades through sustained methodological advancements.However, the multifaceted nature of soil functions and complexity of assessment objectives and scales continue to pose significant challenges.In this study, bibliometric analysis was applied to systematically present the deve
In this paper,the research of the scraper conveyor is carried out,the force analysis of the adjacent middle pan group and the dumbbell pin is carried out,and the dumbbell pin load data is obtained by the dumbbell pin load test system.The ANSYS/ls-dyna software is used to simulate the nonlinear contact dynamics of the middle pan group and the dumbbe
