This study was conducted to assess the water quality affected by different land use patterns in U Minh Ha National Park, Ca Mau, Vietnam. determined characteristics three types (Acacia hybrid, planted melaleuca cajuputi, and natural cajuputi) at plant ages on two acid sulfate soil layers rainy season (8/2018) dry (4/2019) using nine parameters. Multivariate statistical analyses were applied eva...

We report two ESIPT active novel fluorescent probes, 1 and 2, based on benzoxazole benzimidazole units, respectively. Their sensing aptitude towards metal ions in aqueous media is reported. A specific response of to Al3+ and, a lesser extent, Zn2+, was found, while the emission 2 highly impacted by Al3+, Cu2+, Fe2+ Fe3+ either blue shift or quenching emission. Emission also shows relative sensi...

Abstract. The theoretical vibrational properties of a series Fe- and Al-bearing lizardite models have been determined at the density functional theory level. Each periodic model displays single cationic impurity substituted an octahedral or tetrahedral site supercell (Mg3Si2O5(OH)4) containing 162 atoms. isovalent Fe2+ for Mg2+ substitution has considered, as well heterovalent Fe3+ Al3+ Si4+. C...

Cu- and Pd-catalyzed arylation of aminocholanes has been described for the first time. While this Cu-catalyzed protocol provides high yields in reactions of aminocholanes with iodoarenes, Pd catalysis was found to be preferable for the reactions of aminocholanes with dichloroanthraquinones. UV-vis titration of bis(cholanylamino)anthraquinones with a series of cations demonstrated their high bin...

InthedecadesinceKenRobertswroteaboutanending to the30-year febrile infant odyssey,1 the quest for optimal management continues. A recent evidence report by the Agency for Healthcare Research and Quality leaves the question unanswered,2 and an American Academy of Pediatrics subcommittee is actively addressing this issue. The study by Byington et al3 in this issue of Pediatrics makes several impo...

PURPOSE The activity of Al3+, Ga3+, and Be2+ ions in the presence of NaF to directly activate G-proteins was investigated by their potentiative effect on forskolin (FSK)-activated adenylyl cyclase in rabbit ciliary process membranes and their effects on aqueous humor dynamics in vivo. METHODS Adenylyl cyclase (AC) was determined by radiometric conversion of ATP to cAMP by the particulate frac...
