[1] We investigated whether one or a few coupling functions can represent best the interaction between the solar wind and the magnetosphere over a wide variety of magnetospheric activity. Ten variables which characterize the state of the magnetosphere were studied. Five indices from ground-based magnetometers were selected, namely Dst, Kp, AE, AU, and AL, and five from other sources, namely aur...

Introduction: Normal exposure to sunlight results in the production of vitamin D in human body, which happens because of the interaction between ultraviolet radiation and cholesterol in skin. Exposure to sunlight is responsible for 90 percent of vitamin D needed for the body. Studies show that Iran is a country with high percentage of lack of vitamin D (83 percent). Based on pr...

•Uranium(IV)-imido/-oxo complexes have been made by a disproportionation method•The imido and oxo show anomalously high low-temperature magnetic moments•The strong ligands generate pseudosymmetric electronic structures•The resulting pseudo-doublet ground states explain the anomalous magnetism Uranium (U) its derivatives play key roles in nuclear technologies; therefore, it is of interest to stu...
