A novel ultrasonic steel horn with a Bézier profile is developed. The first longitudinal displacement mode of the horn is exploited for high displacement amplification. An optimization scheme and finite element analyses are used to design the horn. The displacement amplification and stress distribution characteristics of the Bézier horn and catenoidal horn are examined. Prototypes of the horns ...

Rudimentary horn is an anatomic variant of unicornuate uterus which a mullerian duct anomaly resulting from the incomplete fusion ducts. The prevalence congenital uterine malformations about 3.2%Pregnancy in rudimentary extremely rare condition occurring 1 76,000 to 1,40,000 pregnancies. Unicornuate with maybe associated gynecological and obstetric complications like infertility, endometriosis,...

Horn players have observed that timpani strokes can interfere disruptively with their playing, especially when they are seated close to the timpani. Measuring the horn's transfer function in the bell-to-mouthpiece direction reveals that the horn behaves as an acoustic impedance matching device, capable of transmitting waves with pressure gains of at least 20 dB near horn playing resonances. Dur...

Resistance to insecticides remains a major problem for the successful control of the horn Xy, Haematobia irritans irritans (L.), one of the most important pests of cattle in many countries including the United States. The organophosphate (OP) insecticide diazinon has been used to control pyrethroid-resistant populations of the horn Xy. There are only a few reported cases of horn Xy resistance t...

Scarab beetles exhibit an astonishing variety of rigid exo-skeletal outgrowths, known as "horns". These traits are often sexually dimorphic and vary dramatically across species in size, shape, location, and allometry with body size. In many species, the horn exhibits disproportionate growth resulting in an exaggerated allometric relationship with body size, as compared to other traits, such as ...
