Olfactory neuroblastoma is a peripheral primitive neuroectodermal tumor related to Ewing sarcoma.

Olfactory neuroblastoma (ONB) is a malignant tumor of the nasal mucosa whose histogenesis is unclear. A relationship to neuroblastoma (NB), a pediatric tumor of the sympathetic nervous system, is based on morphologic similarities and the expression of similar neural antigens. However, the clinical presentation of ONB differs from that of NB, and MYCN amplification characteristic of NB is not observed.

Idiopathic granulomatous mastitis. A report of three cases and review of the literature.

We report three cases of idiopathic granulomatous mastitis that occurred in women of reproductive age (range, 25 to 36 years). These patients presented with breast masses of 2.5, 7, and 10 cm.

Mount st. Helens eruption of 18 may 1980: air waves and explosive yield.

Strong atmospheric acoustic-gravity waves were recorded by sensitive microbarographs and seismographs at large distances from the Mount St. Helens eruption of 18 May 1980. Wave signatures were similar to those of waves from large nuclear explosions.

Concorde sonic booms as an atmospheric probe.

Infrasound generated by the sonic boom from the inbound Concorde supersonic transport is recorded at Palisades, New York (Lamont-Doherty Geological Observatory), as a series of impulses from distances varying from 165 to about 1000 kilometers. Refraction effects determined by temperature and wind conditions return the signal to the surface from both stratospheric (40 to 50 kilometers) and thermospheric (100 to 130 kilometers) levels. The frequency of the recorded signal is a function of the level of reflection; the frequency decreases from impulse stretching as the atmosphere becomes more rarified relative to the sound pressure.

Meteors and meteorites detected by infrasound.

The Lamont-Doherty tripartite array of microphones has detected acoustic signals from meteors. These signals yield trace velocities which vary rapidly from supersonic to nearly infinite values for successive waves or wave groups, indicating a rapidly moving source. The trajectory is constructed on the basis of an assumption of reasonable path elevations.

Sound from apollo rockets in space.

Low-frequency sound has been recorded on at least two occasions in Bermuda with the passage of Apollo rocket vehicles 188 kilometers aloft. The signals, which are reminiscent of N-waves from sonic booms, are (i) horizontally coherent; (ii) have extremely high (supersonic) trace velocities across the tripartite arrays; (iii) have nearly identical appearance and frequencies; (iv) have essentially identical arrival times after rocket launch; and (v) are the only coherent signals recorded over many hours. These observations seem to establish that the recorded sound comes from the rockets at high elevation.

Milankovitch radiation variations: a quantitative evaluation.

A quantitative determination of changes in the surface temperature caused by variations in insolation calculated by Milankovitch has been made through the use of the thermodynamic model of Adem. Under extreme conditions, mean coolings of 3.1 degrees and 2.

Infrasound at long range from saturn v, 1967.

Two distinct groups of infrasonic waves from Saturn V, 1967, were recorded at Palisades, New York, 1485 kilometers from the launch site. The first group, of 10-minute duration, began about 70 minutes after launch time; the second, having more than twice the amplitude and a duration of 9 minutes, commenced 81 minutes after launch time. From information on the Saturn V trajectory and analysis of recorded data, it is established that the first group represents sound emitted either by the first stage reentry or by the second stage when its elevation was above 120 kilometers.

Alaskan Earthquake of 27 March 1964: Remote Seiche Stimulation.

After the intense Alaskan earthquake of 27 March 1964, unusual waves up to 6 feet (about 2 meters) in height occurred at about the time of arrival of seismic waves at many localities along the coasts of Louisiana and Texas. The parameters of local channels at the tide gauge in Freeport, Texas (the only instrument to record significant waves) yield seiche periods close to those of the seismic surface waves suggesting that the water waves were generated by and in resonance with the seismic waves.

Sea Level and Climate of the Past Century.

During the past century global temperatures increased until about 1940, after which there was a decrease. Precipitation trends show a decrease from 1900 to 1940, and a definite global increase thereafter. Sea level trends for the eastern coast of the United States are parallel to, and presumably related to, the climatological changes.

On Pleistocene Surface Temperatures of the North Atlantic and Arctic Oceans.

Two additional interpretations are given for the important data of D. B. Ericson on the correlation of coiling directions of Globigerina pachyderma in late Pleistocene North Atlantic sediments with ocean surface temperatures.
