Theoretical investigations into the bonding and separation properties of non-rigid, partially rigid, and rigid ligands derived from Et-Tol-PTA with trivalent lanthanides and actinides.

The separation of trivalent actinide elements from lanthanide elements represents one of the most formidable challenges within the context of nuclear waste partitioning and transmutation (P&T) processes. Consequently, we embarked on a systematic investigation aimed at elucidating the bonding properties and thermodynamic behavior of a -ethyl--tolyl-2-amide-1,10-phenanthroline (Et-Tol-PTA) ligand in conjunction with trivalent actinide and lanthanide elements. This investigation involved the utilization of various density functional theory (DFT) methods and a comparative analysis between small-core pseudopotential basis sets and all-electron basis sets.

Prevalence of sexually transmitted infections among long-distance truck drivers in Tongling, China.

Little is known about sexually transmitted infections (STIs), including HIV, among truck drivers in China. A cross-sectional study was conducted among truck drivers in Tongling of Anhui Province. A total of 550 truck drivers were interviewed with a structured questionnaire, and blood samples were collected and tested for HIV, syphilis, and herpes simplex virus 2 (HSV-2), and urine specimens for Neisseria gonorrhoeae and Chlamydia trachomatis.
