چکیده
sex once a week or more often, as compared with 56% of the older women.4 In addition, adolescents practicing serial monogamy may use oral contraceptives effectively during a relationship and then discontinue use when it ends; when a new relationship begins, they may be unprepared and use no method.5 Adolescents may also experience more frequent condom breakage or slippage and higher rates of missed pills than older women because of their inexperience with contraceptive use.6 The most common method of emergency contraception used in the United States is the “Yuzpe” method, an oral regimen of 200 mcg of ethinyl estradiol and 1.0 mg of dlnorgestrel. Women take half of the dose within 72 hours of unprotected intercourse and the rest 12 hours later.*7 The Yuzpe method reduces the risk of pregnancy after unprotected intercourse by 75% and could decrease the need for abortion by 50%.8 Other methods also are used for emergency contraception: a copper IUD inserted within 5–7 days of unprotected intercourse, high-dose estrogen, high-dose progestin, danazol and mifepristone.9

Structures and relative stability of neutral gold clusters: Aun (n=15-19).
We performed a global-minimum search for low-lying neutral clusters (Au(n)) in the size range of n=15-19 by means of basin-hopping method coupled with density functional theory calculation. Leading candidates for the lowest-energy clusters are identified, including four for Au(15), two for Au(16), three for Au(17), five for Au(18), and one for Au(19). For Au(15) and Au(16) we find that the shel...

Calcium phosphate cement (CPC) is used in bone repair because of its biocompatibility. However, high similarity between CPC and the natural osseous phase results in poor image contrast in most of the available in vivo imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI). For accurate identification and localization during and after implantation in vivo, a com...
