Background: Diagnosis and management of pre-rupture stage of the pregnant horn are difficult and usually missed on a routine ultrasound scan. Furthermore, most cases are detected after rupture of pregnant horn. Case: We presented a 28-year-oldG2 L1 woman with diagnosis of RHP at 14 weeks of gestation. She was initially diagnosed with a normal intrauterine pregnancy, whereas a pregnancy in a rig...

We introduce a Horn description logic called Horn-DL, which is strictly and essentially richer than Horn-Reg , Horn-SHIQ and Horn-SROIQ, while still has PTime data complexity. In comparison with Horn-SROIQ, Horn-DL additionally allows the universal role and assertions of the form irreflexive(s), ¬s(a, b), a 6 . = b. More importantly, in contrast to all the well-known Horn fragments EL, DL-Lite,...

Horn-to-Horn belief revision asks for the revision of a Horn knowledge base such that the revised knowledge base is also Horn. Horn knowledge bases are important whenever one is concerned with efficiency—of computing inferences, of knowledge acquisition, etc. Horn-to-Horn belief revision could be of interest, in particular, as a component of any efficient system requiring large commonsense know...

Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by...

The tendency for flower longevity to increase with altitude is believed by many alpine ecologists to play an important role in compensating for low pollination rates at high altitudes due to cold and variable weather conditions. However, current studies documenting an altitudinal increase in flower longevity in the alpine habitat derive principally from studies on open-pollinated flowers where ...

A new horn with high displacement amplification for ultrasonic welding is developed. The profile of the horn is a nonrational B-spline curve with an open uniform knot vector. The ultrasonic actuation of the horn exploits the first longitudinal displacement mode of the horn. The horn is designed by an optimization scheme and finite element analyses. Performances of the proposed horn have been ev...

Abortion in an attached rndimentary uterine horn, followed by a normal intrauterine pregnancy.  Pregnancy in an rudimentary uterus has been occured in many forms, and up to now about 350 cases have been reported in medical journals. Most of these malforma­tions accompanied with other malformations in urinary tract.  A case of pregnancy and abortion in an attached rudi­mentary uterine horn is ...

Resting cyst and motile thecate cell stages of three heterotrophic Protoperidinium oblongum, Protoperidinium sp < b> and Protoperidinium claudicans were assessed. Cysts were isolated from sediment collected from southeast coast of Iran. Individual live cysts were incubated under optimal conditions for germination. Results showed that Protoperidinium oblongum cysts were pentagonal smooth walled ...

Purpose: To evaluate the phytochemical profile as well as in vitro antioxidant, iron-chelating, and antiglucosidase activities of Typha domingensis Pers. (Typhaceae) Methods: Total polyphenols, flavonoids, hydroxycinnamic acids, and pro-anthocyanidins in the respective aqueous extracts of male and female flowers, and fruit of T. domingensis were determined by established procedures. Antioxidant...
