  • They were in the garden. "Now, Zoe," said Zenia Hawkins to her nineyear-old daughter, "quit fluttering around, and papa will tell you a story." Zoe settled down in the hammock. "A true story, papa?" "It all happened exactly like I'm going to tell you," said Drake Hawkins, pinching Zoe's rosy cheek. "Now: two thousand and eleven years ago in 1985, figuring by the earthly calendar of that time, a tribe of beings from the Dog-star Sirius invaded the earth." "And what did these beings look like, father?" "Like humans in many, many respects. They each had two arms, two legs...

  • Palpitations may be reported by patients as sensations of flipping, stopping, pounding, or fluttering of their heart. Abrupt onset and offset of rapid, sustained palpitations suggests supraventricular or ventricular tachycardia. If the sensation associated with the palpitations is accompanied by dizziness, presyncope, or syncope, then ventricular tachycardia needs to be excluded.

  • The trap had closed at sundown. In the last red light, the rabbit had battered himself against its walls until fear and numbness ached home and he crouched shaken by the flutterings of his heart. Otherwise there was no movement in him as night and the stars came. But when the moon rose, its light was caught icily in his great eyes, and he looked through shadows to the forest.

  • A butterfly is a mainly day-flying insect of the order Lepidoptera, which includes the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of four parts: egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). All the many other families within the Lepidoptera are referred to as moths.

  • A senior-level undergraduate course entitled “Vibration and Flutter” was taught for many years at Georgia Tech under the quarter system. This course dealt with elementary topics involving the static and/or dynamic behavior of structural ele- ments, both without and with the influence of a flowing fluid. The course did not discuss the static behavior of structures in the absence of fluid flow because this is typically considered in courses in structural mechanics.

  • The stem, which connects the actuator and disk, is responsible for positioning the disk. Stems are typically forged and connected to the disk by threaded or welded joints. For valve designs requiring stem packing or sealing to prevent leakage, a fine surface finish of the stem in the area of the seal is necessary. Typically, a stem is not considered a pressure boundary part. Connection of the disk to the stem can allow some rocking or rotation to ease the positioning of the disk on the seat. Alternately, the stem may be flexible enough to let the disk position itself against the seat.
