Throughout the Late Neogene, the Black Sea experienced large paleoenvironmental changes, switching between (anoxic) marine conditions when connected to the Mediterranean Sea and (oxic) freshwater conditions at times of isolation. We create a magnetostratigraphic time frame for three sites drilled during Deep Sea Drilling Project (DSDP) Leg 42B to the Black Sea (drilled in 1975). At the time, ma...

BACKGROUND Intrauterine contraception is a first-line option for young women, yet relatively few prospective studies have been performed in nulliparous women using currently available devices, and many providers are still reluctant to provide this option. METHODS Between January 2012 and June 2014, 109 nulliparous women, aged 18-30 years, who had an intrauterine device (IUD) placed at a stude...

The Intrauterine Device (IUD) is the second most common contraceptive method used throughout the world after sterilization. Usage is estimated at 15% of reproductive women worldwide (160 million women) (1). The Copper (Cu) T 380A, which is one of the latest generation copper IUDs, provides significant contraception (99%) for 10 years with a very low expulsion rate (2). Recent studies have shown...

We report hyperfine-resolved scalar polarizabilities for cesium’s 8s S1/2 and 9s S1/2 states using resonant two-photon spectroscopy in both an effusive beam and a vapor cell. Electric-field strengths are measured in situ, and the frequency scale is directly referenced to the ground-state hyperfine splitting of atomic rubidium. The measured 8s S1/2 scalar polarizability is 38 370± 380a 0 , which...
