We investigate the feasibility of robust abundances for selected neutron-capture elements (Ge, Bi, Hf, U) from near-UV spectroscopy with CUBES instrument now in development Very Large Telescope. use end-to-end simulator to synthesise observations Ge I 3039 {\AA} and Hf II 3400 3719 lines a very metal-poor star, using well-studied star CS 31082-001 as template. From simulated 4 hr exposures, we ...

Introduction: Inappropriate management of mining activities may bring about water pollution and pose a heavy complication on aquatic ecosystem and humans. The study aimed to evaluate the effect of Qorveh gold mining activities on the quality of nearby groundwater. Materials and Methods: The concentration of seven eco-toxic metals along with some general hydrochemical parameters were investigat...

The spectrum of states in very heavy and super nuclei is the result a delicate balance between strong Coulomb repulsion numerous protons nucleus properties force acting many nucleons system. Fine-structure $$\alpha $$ decay combined with $$\gamma -ray internal-electron-conversion spectroscopy allows to identify sequence energies low-lying nuclear states. This information can then be used constr...

Recent dynamical analysis based on Gaia data have revealed major accretion events in Milky Way's history. Nevertheless, our understanding of the primordial Galaxy is hindered because bona fide identification most metal-poor and correspondently oldest accreted stars remains challenging. Contrary to alpha-elements, neutron-capture elements present unexplained large abundance spreads for low metal...

the study of world health organization (who) has shown that the use of herbal medicines has been increased dramatically around the world in recent years. with the expanding popularity and trade of medicinal plants, health, safety and quality of medicinal plant raw materials and processed products have become a major concern for world organizations. environmental pollutants, including heavy meta...
